The invention relates to a method for manufacturing pads for brake linings, in particular for disc brakes of the vehicle, strip or plate, the workpiece is subjected to deep drawing in the direction perpendicular to the plane of the workpiece. In addition, the invention relates to a pad for the brake pads, and processing unit, in particular a stamping instrument for the method.

Pad for brake lining is known, for example, in connection with disc brakes of vehicles and forms together with placed on it by the brake lining brake pad. Brake pad is designed for connection through the block for the brake pads from the caliper disk brake mechanism. Bracket disk brake mechanism has at least one piston, with which a brake pad is moved to the brake disk of the disk brake. During the process of braking pad to the brake pads is used for transmission with the brake pads on disc brake bracket mechanism of shear forces that are generated due to the contact between the brake lining and brake disc. On the basis of a large mass, in particular, vehicles for the transport of goods or passengers, such as, for example, trucks, and requires�IIR due to this, when large braking force of the braking to pads for brake linings, respectively, equipped with their brake pads must meet especially high requirements for rigidity of their form. Therefore, the pads for the brake pads must have, in particular, greater Flexural strength to protect against deformation and/or destruction.

Known manufacturer of brake pads for brake lining by way of casting, as shown, for example, in DE 195 32019 C1 and DE 103 50725 A1. Furthermore, from DE 10 2004 014858 A1 and DE 20 2005 011 660 U1 known stamped from steel sheet pads for brake linings and rolled pads for brake linings from DE 103 00585 v3.

From DE 10 2004 054012 A1 is known to strip for brake lining, which is made by deep drawing from sheet metal. Compared with the manufacture of foundry manufacturing method by means of deep drawing has the advantage that there is no need for post-treatment. In addition, manufactured by deep drawing pad for brake lining has a significantly lower weight than the ones made by foundry way pad for the brake pads. This weight reduction has a positive effect on the movement characteristics and the fuel consumption has such a block for the brake pads of the vehicle. In addition, it should be noted that manufactured by�m casting block for the brake pads has the worst properties of the material, than is made by deep drawing pad for the brake pads. The material manufactured by the method of casting brake pads for brake lining is fragile. Due to this, under extreme conditions for brake pad lining can break down.

Relatively used up to the present time pads for brake linings should be noted that they have a relatively large weight, which is associated with the above-mentioned disadvantages. In addition, to date the manufacture of brake pads for brake linings of steel, is macoeconomics, since it requires steel sheets with relatively large material thickness to provide the required and customary installation dimensions.

To ensure a sufficient holding force between the bracket disk brake mechanism in a modern design and a brake Shoe, it is expedient to provide on the side of the bracket disk brake mechanism of the protrusions of the material as elements fit in certain positions on the edge of the pads for brake linings. These protrusions interact with the material form of the bracket disk brake mechanism, so that the occurring during braking, lateral forces can be transmitted to the calliper disc brake mechanism. At the same time it must be drainage impact�following the brake pad shear forces in the pad for the brake pads. This turned out to be suitable, in particular, shaping block for brake lining, whereby to accommodate brake lining is formed of a fully edged recess on the block for the brake pads.

To date, the manufacture of brake pads for lining with the above features, i.e. arranged on the side of the bracket disk brake mechanism with the ridges of the material and edged on the side of the brake lining of the recess, was possible only by using a molding method.

With this in mind, the object of the invention is to provide a method of manufacturing brake pads for lining, which is economical and which prevents the disadvantages indicated above.

This problem is solved based on the method specified at the beginning of the form so that the workpiece to create at least one located on the edge of the thickening material is crimped transversely, in particular perpendicular to the direction of deep drawing, the thickness is designed so thickening of the material is greater than the thickness of the source material.

The invention is directed to the manufacture of brake pads for lining through deep drawing of a metal workpiece (e.g., steel sheet). The manufacturing method is as follows from the above, to create pads for the brake nakladka improved compared to the manufactured molding strip for brake lining material properties. In addition to this, should not be performed post-processing, which is inevitable when manufactured by molding the Shoe to the brake pads. Thus, the ability to manufacture pads for brake linings according to the invention, in a shorter time and thus more economical than custom molding pads for brake linings.

By creating, according to the invention, located at the edge thickening material of a given size, you can implement the forms and functions of the pads for the brake pads, which have so far only been achieved in custom molding pads for brake linings. Thickening of the material forms located on the side of the bracket (caliper) disc brake mechanism of the protrusion of material which, as indicated above, there is provided in a suitable position on the edge of the pads for brake linings. Thickening of the material increases the strength of the pads for the brake pads and extends its functionality. Thickening of the material forms an element of the fit, which interacts with the surfaces or functional surfaces of the bracket (caliper) disc brake mechanism. Through the element of the fit generated by braking lateral force can securely p�to radovatisia with pads for the brake pads to the calliper disc brake mechanism. According to the invention, of crucial importance is the fact that the thickness created by the thickening of the material is greater than the thickness of the starting material (e.g., steel sheet used). Thus, it is possible to apply the original material without negative effect on the dimensional stability of the finished product, much thinner than the total thickness of the finished pads for brake linings. Depending on application, the thickness of the thickening of the material may exceed 1.1-2.0 times the thickness of the starting material. Typically, the thickening material is 30-50% thicker than the original material. This significantly reduces the cost and weight. In addition, a significant advantage is the fact that intended for normal pads for brake pad bracket disc brake mechanism can remain without change for use with pads for brake linings according to the invention.

Using the method according to the invention, are preferably made by deep drawing pad for brake lining, which is on the side of the brake pads fully edged by deepening and elevation simultaneously located on the side of the bracket disk brake mechanism of the above-mentioned protrusions of the material.

Thus, according to the invention, the above p�of akusherstva made of sheet metal pads for brake linings namely their good properties of the material, combined with advantages of made molding pads for brake linings, namely, their optimal form.

Using the method according to the invention can be performed, for example, two or more, in particular four retaining tabs on the side of the bracket disk brake mechanism on the edge of the pads for the brake pads, which provide enough contact surface and thereby improves the retention pads for the brake pads on the corresponding bracket disk brake mechanism and create a stable mechanical connection between the bracket disk brake and pad for the brake pads. The corresponding two retaining tabs are used to transmit forces in circumferential and radial direction from the pads to the brake pads on disc brake bracket mechanism.

According to one preferred embodiment of the invention, in the workpiece are performed by deep drawing a landing in the form of a recess, the inside contour of which is compatible with the form to be installed on the block brake linings. The recess forms a lower edge of a recess contact surface for the brake pads. Thus, the creation deepened by deep drawing is used to�education of the receiving element for the brake pads. Border of the recess has an inner contour which is matched to the shape to be connection with the brake Shoe lining. Preferably facing the strip for the brake lining brake lining is made with the possibility of entering an interlocking in the groove. Due to this is an optimal connection between the pad and the brake lining, wherein, in particular, acting on a brake lining during braking, lateral forces are perceived, at least partially, surround the groove.

According to one preferred embodiment of the invention, the pad for the brake pads is located on the side of the brake lining surface edging at least one surrounding the recess completely or partially restrictive protrusion or guide groove. The task of restraining ledge or restrictive deepening is to limit the expansion of the brake lining in the direction parallel to the surface pads for brake linings. The edging of the recess serves to provide stability pads for brake linings and at the same time as the joint area for the tool by means of which the brake lining is applied to the pad for the brake pads. The brake lining material nano�is designed in the form of pulp in the plastic state with a tool on the block for the brake pads and then hardens. The material is made so the brake pads as a rule, to a certain extent, also covers the edge of the recess. In this case, there arises the problem of increase in the volume of the pulp (in particular, when it comes to dry pulp) during solidification. This means that changing the extension of the pulp and thereby the contour of the brake lining on the rim of the recess. To counteract this may be provided in the protruding lip or restrictive deepening. It is advisable, they form on the piping completely or partially surrounding the recess wall, respectively, of the groove as a means of form closure, which effectively limit undesirable expansion (increase in volume) brake lining in the direction parallel to the surface pads for brake linings. The protruding lip or bounding the recess can advantageously be created by deformation of a sheet or plate of the workpiece. Preferably, the protruding lip or restrictive recess having substantially V-shaped cross-section.

According to another preferred embodiment of the invention, the speaker after deep drawing-side edge of the material is removed by punching for the formation of a predetermined outer contour. Education topically�about the circuit through the stamping is advisable, since thereby for the manufacture by means of deformation (deep drawing, crimping and cutting (punching) requires only one tool. More detail is explained below.

It is also proposed that the workpiece during swage across the direction of deep drawing at the same time also deformed in the direction of deep drawing. Through active during deformation in the deep drawing direction of force the part is clamped and fixed. A simultaneous action of force in the deep drawing direction and in the direction perpendicular to it, generally results in the flow of the material of the workpiece to the desired (specified using the appropriate tool) form.

In another preferred embodiment of the invention provides that the workpiece before clamping or crimping is provided transversely, in particular perpendicular to the direction of deep drawing in preset locations of the holes and/or at least one provided in a specified location on the edge of the recess. The recess can be, for example, a hole in the block for brake linings for wear indicator. Thus, the working stroke of the creation of holes, respectively, the cut can be used to secure the workpiece on the tool during crimping.

In addition, it is proposed that prior to stamping, �on time stamping or during deep drawing, in the area create indentations on the side of the brake lining holding brake lining fingers. Holding brake lining fingers serve to further improve the retention between the pad for brake lining and brake lining. After the formation of the holding brake lining fingers in the area of the recess that holds the brake pad fingers are at least a predetermined located on the side of the brake lining surface pads for brake linings and at the location in accordance with the purpose of the brake pads on the strip for the brake pads are in the recesses on the brake pad. This results in fixing flush the brake pads on the block for the brake pads, in any case, in the circumferential direction. Holding brake lining fingers can have a circular or polygonal cross section. Preferably located on the side of the bracket disk brake mechanism of the surface of the recess formed by the indentation (indentation) in places where located on the side of the brake lining surface of the recess formed by the retaining brake lining fingers in the form of elevations. Holding brake lining fingers are preferably made in the form of single p�logo with the rest of the block for the brake pads and is formed by pushing the shaped body material in pads for brake linings in the area of the recess.

Specified latest variant of the invention serves primarily to provide improved retention of the brake pads on the block for the brake pads. In the prior art execution in the block for the brake pads holes, which are included in the corresponding fixing axle brake lining. At the same time the brake lining is glued to the strip for the brake pads. However, regarding the high braking temperatures can lead to combustion of the adhesive. In this case, the brake lining is held on the block for the brake pads only, with mounting pins. Due to this, the brake lining can be loosened and slightly lifted with pads for brake linings. In extreme case can occur then the tearing of the fastening pins generated by braking transverse forces. Furthermore, the known brake pads in pads for brake linings made of, for example, holes that are filled during the pressing weight of the brake pads. Furthermore, it is known formation on the surface of the pad to the brake pads of other holding members for holding the brake pads. The retaining elements are made pads for brake linings in the form of additional parts, for example, in the form �riverandah or sintered bars or pins. In contrast, forced, according to the invention, the shaped body into the material of the workpiece in the zone of the recesses for the formation of a holding brake lining toes provides much more simple, cheaper and yet efficient option for the connection pads and brake linings.

In addition, the subject invention is manufactured using the above method block for the brake pads. In this strip for the brake pads preferably are located at the edge of two or more retaining protrusions in the form of thickening material, wherein the retaining tabs provide retention pads for the brake pads on the caliper disk brake mechanism in the circumferential direction and possibly also in the radial direction. Is the performance consistent with the currently used clamps disk brake mechanism. The retaining protrusions formed according to the invention, in the form of a single whole with the rest of the block for the brake pads, with no increase for the expense of material, as required, for example, in the prior art. Due to the location of the four retention tabs is provided particularly good holding pads for brake pads currently used in most cases, the staples disk�about the brake system. Generated by braking lateral force may very well be transferred from the pads to the brake pads on disc brake bracket mechanism.

As an alternative solution, the invention relates to a pad for a brake lining, which is made by deformation and stamping of sheet or plate-like workpiece and is surrounded by fringing, located on the side of the brake lining the recess (disembark), the inner contour is consistent with the form to be connection with the brake Shoe lining. On the edge of the pads for the brake pads are holding projections which, as indicated above, provide retention and/or direction pads for the brake pads on the caliper disk brake mechanism, and welded, bolted or riveted with the workpiece. For this purpose, the retaining protrusions can be profiled elements or strips of steel, which are connected in the appropriate places subjected to deep drawing a blank.

In addition, the above problem is solved by using a processing device, which has a first work area for deep drawing of sheet or plate-like workpiece in a direction perpendicular to the plane of the workpiece, the second working portion for crimping at least one boundary zone zagotovka� to create a located on the side edges of the thickening of the material in a direction crosswise in particular, perpendicular to the direction of deep drawing, and the third work area for cutting punching subjected to deep drawing of the blank, while the work areas are located next to each other. Such machining device is also known as a progressive die. The workpiece passes successively through separate working areas, for example, during successive strokes of the respective stamping press, and the various sequences of the location of work stations in the manufacturing device. The processing device can work so that the work areas are active simultaneously and in parallel, so is simultaneous processing of multiple workpieces. It should be noted that the number of work stations handling device according to the invention is not limited to three sections. Depending on application it may be appropriate for more or fewer stages of processing, and thus the corresponding number of workstations.

In one preferred embodiment of the invention provides that the second portion has at least one running across the direction of deep drawing crimp pusher, and at least one pocket into which flows �icecreamy crimping pusher material of the workpiece. On the basis of crimping the formation of the desired located on the side edge of the thickened material. To control their size and shape is provided with the appropriate form pockets in the manufacturing unit.

Preferably, the second working portion includes means for the formation of holes and/or processing of the workpiece from the side edges. Processing from the side edges of the workpiece can be, for example, to create recesses, designed for positioning it in subsequent wear indicator disc brakes.

Preferably, the third working phase or the second working portion includes facilities for education are located on the side of the brake lining holding brake lining fingers. Thus, the second or the third work area can be simultaneously performed in a single step manufacture restraint brake lining fingers.
