Then perform a second extraction and scrubbing through corpsebride device with the aim of refining the side surfaces and increase the height of the housing container. In composeessay machine can be included odnoobrazie or svodoobrazuyuschih device. Metal body or container is pulled through corpsebride device using a punch or stamp. Proposed in the present invention instrumental batch device designed for use in combination with corpsebride device for producing two-part containers. In particular, it is proposed in the present invention instrumental batch device forms an inner annular housing, coaxially with the punch or stamp. It is important that the movable punch component moves smoothly through the inner case.

Instrumental batch device can have various combinations of components, including, for example, stamps for secondary hoods, single or double matrix kits, splitters and/or separators for cooler depending on size limitations or requirements to which the size and the desired processing or effects on the body of the container. For example, proposed in the present invention instrumental batch device may have a stamp holder for the secondary drawing, the element stamp for the secondary drawing, the first single modular matrix separation element, the second single modular matrix, the second separator element, separator element for cooler and third single modular matrix. Elements Toolkit, form a housing for the matrix sets used for thinning the side surfaces of metal containers. Matrix kit may include, for example, a die-holder and the stamp. With the case reported holes for coolant/lubricant through which to form the metal enters the cooler. In the forging process buildings of metal containers using instrumental devices and corpsebride device generates heat. In case of violation of the centering body of the container and/or excessive heating in corpsebride device problems arise in the production and quality assurance, i.e. the gap and re-melting. As a result of this you may need to stop corpsebride device to retrieve the damaged product(s), resulting in reduced productivity and efficiency. Thus, the advantage of this is subramania is instrumental in creating a batch device, minimizes the problems of production and quality assurance.

Modular matrix has a generally circular ring structure forming a housing for the die-holder and die, through which can pass the body of the container. Side entry modular matrix can be lubricating ring, which communicates with the holes for the coolant/lubricant and is used to evenly apply lubricant/coolant to the body of the container, to facilitate passage through the die and to prevent tearing and melted. On the output side of the modular matrix is a matrix set and provides a number of cavities with corners solution for springs that bias the stamp, thereby providing alignment of the housing container and the stamp. On the input surface of the support matrix provides air channels, which communicate with holes for air intake instrumental in the batch device. Since the matrix set has a tendency to stick to the body unit matrix in the process of forcing case of containers through the Toolkit and corpsebride device, the air flow passing through the channels, causes the Mat the ranks set to move from the surface of the module in mobile, re-centered position.

It is important that the installation of the matrix set at a desired radial position in the housing of the modular matrix provides improved shock absorbing means. Shock absorbing means includes a spring and interacting with it hard contact element or pin of a given shape. The spring is preferably made of elastic material, i.e. urethane or similar elastic compressible polymer or other material with memory and shock absorbing properties similar to urethane.

Description of the preferred embodiments of the invention

Proposed in the present invention instrumental batch device designed for use while drawing and drawing consisting of two parts of the buildings of metal containers. Proposed in the present invention Ann is rumentalnoe batch device designed for use in corpsebride device for the manufacture consisting of two parts of buildings containers. As proposed in the present invention instrumental batch device placed stamps, which form a part of the body of metal containers, as well as advanced single or dual modular matrix with improved cushioning means. Although instrumental batch device may have a different configuration and different interactive elements, below are the approximate instrumental batch device 10.

Figure 1 shows the instrumental batch device 10 with the holder 11 of the stamp for the secondary drawing, the bearing element 12 of the stamp for the secondary hood, single modular matrix 13, the separating element 14, a single modular matrix 15, the separating element 16, the separator element 17 for cooler and single modular matrix 18. Elements 11-18 form the inner housing 35 in which are placed the matrix sets and through which the punch pushes or presses stamped metallic element with the purpose of imparting a metallic container or part thereof. The holder 11 of the stamp for the secondary drawing, the bearing element 12, a single modular matrix 13, 15 and 18 fixed matrix set, namely the die-holder and the stamp. For example, it is shown that the die-holder 23 is adjacent to the receiving ledge 19 of the matrix and asaeda inside of the holder 11 of the stamp for the secondary hoods and support member 12. Similarly it is shown that the die 24, 25 and 26, respectively, adjacent to the receiving projections 20, 21 and 22 of the single matrix unit matrix 13, 15 and 18 and, therefore, are in a single modular matrices and the inner housing 35. Matrix kits are designed in such a way that the metal case is able to pass through the stamp 36 for secondary hoods and stamps 32-34. Shock absorbing means 59, which includes an elastic spring element 60 and a cooperating contact element or pin 65 are placed in the modular matrices, such as modular matrix 18.

As shown in figures 1 and 2, in the upper part of the elements 13-17 are holes 27-31 inlet fluid. Holes 27-31 inlet fluid communicated with the inner housing 35. Holes 27, 29 and 31 to inlet fluid serve for the supply of lubricants or coolants into the housing and the die, and the holes 28 and 30 to inlet fluid serve to supply air into the case. With the aim of improving the quality of the metal housing and reduce damage to the goods, i.e. prevent separation and smelting, metal housing to flow through each stamp is preferably cooled. For example, in the process of applying a metal casing, moving through instrumental batch device 10, a push through a single modular matrix is 15, the die-holder 25 and the stamp 33. Directly after passing through the stamp 32 single modular matrix 13, the temperature of the metal housing increases. In this regard, to flow through the stamp 33 metal body is preferably cooled. Through the opening 29 to the metal may be filed a cooler and put into the lubrication ring (described later with reference to figure 4) single modular matrix 13. Because after jacking matrix kits can stick to the housings of the modules is provided by openings 28 and 30 for air intake, which communicate with the housing 35 and through which the air channel (described later with reference to Fig 3) single modular matrix enters the air, releasing or moving the matrix set relative to the unit matrix.

Shows the matrix modules, separators, coolers and holes for air intake are approximate and may have various configurations depending on operational requirements. For example, figure 1 shows that the modules 13 and 15 holes 27 and 29 for cooler located inside the modules together with means for supplying coolant into the housing 35 for cooling the supplied metal housings. Alternatively, a hole 31 for cooler can be located in the separation element 17 to cool the La and to communicate with a single modular matrix 18. Similarly it is shown that the holes 28 and 30 air inlet located in the separating elements 14 and 16, respectively, and are connected with the modular matrices 13 and 15. Lubricants and air flow can be enjoyed in the instrumental batch device using various tools. For example, the outlet openings of lubricants and air corpsebride device can be aligned with openings for inlet and lubricants air tool batch device. For the purpose of fulfilling requirements for the supply of lubricants and air flow at the tool batch device holes for inlet lubricants and openings for air intake can communicate with the lubricating ring, which is placed, for example, in the modular matrix and/or separating element. In addition, there may be provided a double modular matrix, which is discussed below and is used in instrumental batch device according to the present invention.

Figure 3 shows a single modular matrix 40 with the housing 41 with the wall 44 having radially spaced shaped cavity 45. Single modular matrix 40 is an example of a modular matrix used in the tool package device according to the present invention, for example the EP single modular matrices 13, 15 and 18 instrumental batch device 10. In the housing 41 with the wall 44 is placed matrix set, for example, a die-holder with a stamp. The housing 41 of the modular matrix has an outer surrounding wall 42 and the inner surrounding wall 43. As indicated above, on the surface of the single modular matrix 40 is an air channel 46 shown forms, including eight radially passing grooves 49, the inner annular groove 47 and the outer annular groove 48, all of which are communicated with each other, forming an air channel 46. In the shaped cavity 45 with sloping walls 96 and 97, which are additionally described below, are placed cushioning means, i.e. spring and the contact elements (described later with reference to Fig-10), moving the matrix set in such a way that pushed the punch corpsebride device metal casing, passing through instrumental batch device, combined with the stamp, thereby preventing separation and increases production efficiency and product quality. Shaped cavity 45 is shown generally evenly distributed on the wall 44, however, the present invention provides that shaped cavity 45 can be distributed over the wall 44 otherwise, taking into account, for example, the weight matrix of the set.

As shown at F. the D.3, along the outer surrounding wall 42 single modular matrix 40 are holes 54 to a control unit (not shown). Along the surrounding wall 42 are plate 53 of friction, fixed by means of fasteners 55, i.e. screws. As additionally shown in Fig.6 and 7, each plate 53 of friction there are openings 57 through which the fastening elements 55 are held in cooperating apertures (not shown)located in a single modular matrix 40. It is shown that the plate 53 of friction are outside single modular matrix 40 proposed in the present invention instrumental batch device in two positions, for example, the maximum contact each single modular matrix with rods contractible holder. Thus, the friction plate is designed to withstand high load and in case of wear they can be easily replaced by a more cost-effective and efficient way than when replacing or sanding the entire hull single modular matrix that is currently required in known prior art devices. Proposed in the present invention, the friction plate is preferably made of hard steel or similar material.

As shown in figure 4 and 5, the outer surrounding wall 42 and the inner surrounding wall 43 is the raised outer and inner boundaries of a single modular matrix 40. Shows the internal tapering cylindrical wall 56 communicates with the channel 50 for lubricants, in which the lubricating material is transported from the inlet device in the lubrication ring (not shown)located on the inner cylindrical wall 56. As shown in figure 4, the channel 50 for lubricants has a ring section 52 and eight radially passing sections 51. As described with reference to figures 1 and 2, in the tool package device can be introduced through holes for inlet liquid) refrigerant or lubricant, which (according to the channel for lubricants and internal tapering cylindrical wall 56) can flow in the lubricating ring for cooling and lubrication noise metal case.

On figa shows a view in cross section of a single modular matrix 40 by line 5-5 on figure 3. It is shown that the housing 41 with the wall 44, an inner surrounding wall 43 and the inner tapering cylindrical wall 56 forms a part of the inner casing instrumental batch device, when such single modular matrix is used in instrumental batch device in combination with other elements. As indicated with reference to figure 3, the cross section shown in figure 5, illustrates the inner ring 47 and the outer ring 48 of the air is on channel 46 and shaped cavity 45. As described above with reference to figure 4, the cross section shown in figure 5, the illustrated annular area 52 and one radially passing area 51 channel 50 for lubricants.

On Fig shows the enlarged view of the shaped cavity 45 in the case of single modular matrix 40. Into the shaped cavity 45 includes shock absorbing means 59, which includes the spring element 60 and the contact element 63. Shaped cavity 45 has sloping walls 96 and 97, which form an inclined hole that leads into the shaped cavity, and through which the surface 72 of the friction contact elements or pins 65. It is shown that the shaped cavity 45 additionally has a machined outer edge 69. As shown in Fig and 9, the spring element 60 has a body 61 in a generally elongated oval shape in cross section. On Fig and 9 shows that the housing 61 has a depressed section 62. Through the housing 61 are holes 64, improve functionality and increase the life of the body of elastic springs. As shown in figures 9 and 9a, the housing 61 of the elastic spring element 60 has an outer bottom tabs 70, mounted on a machined outer edge 69 of the fitting cavity 45. This design facilitates the fixation of the spring element and, thereby, cushioning means in the cavity 45. As shown in Fig and 10, the pin or contact ele is UNT 65 has a rigid truncated housing 66 in a generally trapezoidal shape in cross section. The housing 66 has a protruding rear section 67 which communicates with a depressed section 62 of element 60. Speaker rear section 67 additionally has a hole 68 located generally in the center section 67 and communicates with the tab 63 of the spring element 60.

It is important that the contact element 65 preferably has a rigid inclined element 66 of the housing with the adjacent surfaces 72, 73 and 74 of friction. Surfaces 72, 73 and 74 of friction are at an angle 71 of about 40 degrees to the radius of the unit matrix. The angle 71 may be in the range of about 25-55 degrees. As shown in Fig, the pin 65 is preferably departs from the shaped cavity 65, providing contact with the matrix set on the surface 72 of friction and moving it. Surfaces 73 and 74 of friction are generally the same angle and sloping walls 96 and 97 shaped cavity, thereby providing the maximum surface area of friction so that the pin came into contact with the die-holder.

In the present invention greatly strengthened and increased surface friction shock absorbing design in comparison with the constructions known from the prior art pins generally rounded shape, which, in particular, it is shown figure 11. Unlike all of the pins, for example, from the patent '815 improved pin or contact element has a generally t aparajito or truncated form with three friction surfaces, thereby increasing the contact area and the friction surface. The case of an improved spring element may have the pass-through channels or openings (holes 64, shown in Fig and 9), which provide improved parameters of compressibility and durability. The spring elements are preferably made of urethane or similar compressible elastic material with shock-absorbing properties similar to properties of urethane compounds, and set the desired parameters of elasticity and hardness, i.e. according to the testimony of a Durometer. Interactive pin or rigid elements of a truncated form preferably made of tool steel or similar rigid and durable material. In addition, in the present invention can also be applied to the spring element in the form of a cylindrical spring used in conjunction with a pin or the contact element 65, despite the fact that the elastic spring elements are preferred.

The present invention provides that in the tool package device can be used a compound or double modular matrix. Can be used dual modular matrix with a support ring or housing for the accommodation of two adjacent matrix sets. In the case of a double modular matrix also can according to what is proposed to be used in the invention shock-absorbing means to move the United dual matrix kit i.e. many of shaped cavities in which are placed the spring elements and the pins. Shaped cavity dual modular matrix have more depth than the cavity of the single modular matrix. Due to this, the pins used in dual modular matrix, increase the surface area to move two adjacent matrices, and the size of the spring elements is selected so as to correspond to the increased size of the pins.

Proposed in the present invention instrumental batch device may also include various combinations of exhaust and/or pulling items depending on operational requirements. For example, figure 11 shows known from the prior art tool package 75 with an alternative configuration. Instrumental batch device 75 includes a matrix set 76 for secondary hoods, single modular matrix 77, dual modular matrix 78, single modular matrix 79 and dividers 94 and 95. In single modular matrices 77 and 79 are placed matrix sets 80 and 83, respectively. Double modular matrix 78 inside of the bearing rings 87 are matrix sets 81 and 82. The above support ring serves to move the matrix sets in dual modular matrix in synchronous mode or as a whole. Inside the modular matrices 77, 78 e are cylindrical spring 84. It is shown that in a single modular matrix used is known from the prior art round pin 85, and dual modular matrix used is known from the prior art round pin 86, which communicates with both coil springs double modular matrix. As indicated above, when using the combination of a spring and pin shown on Fig-10, dual modular matrix can also be used one elongated pin and a cooperating spring element. It is shown that the modular matrices and matrix sets are communicated to the holes 88, 90 and 92 to the inlet of lubricants and holes 89, 91 and 93 for air intake.

The above configuration tool batch devices are exemplary, and the scope of the invention also includes the application of the proposed invention stamps for secondary hoods, dividers, single matrix sets and/or double matrix sets in any combination. In addition, any individual batch device, the lubricating ring (not shown), the holes for inlet lubricants and openings for air intake may be provided in different positions, for example in the separation element or unit matrix.
