(57) Abstract:

Usage: the equipment for sheet metal forming, in particular for cutting with die form articles of complex configuration. To the base form attached metal loop, made of cutting lines, and the formwork, which together with the contour fill of the solidified material. Leaves free from filling the cutting edge contour to a height of 2-10 mm To achieve a repetition accuracy of the configuration of the cut product contour set along the lines of the drawing, which is placed on the plate of the hard magnetic material providing a stable position of the contour on the stove, due to the magnetic forces of adhesion that simplifies the way. 1 C.p. f-crystals, 1 Il.

The invention relates to a sheet punching, in particular cutting with die form articles of complex shape, for example of cardboard packaging.

A known method of manufacturing a die shapes for cutting products offered by industrial group "RASTER-TECHNOLOGY", which is a laser treatment to obtain with high precision grooves along the contour of the cut item into which you insert the cutting line. This is to the invention is a method of manufacturing a die shape by attaching to the base form of a metallic circuit, performed configuration of manufactured products, and the subsequent consolidation of its hardening filler.with. The USSR 963621, the IPC 21 D 37/20, publ. 07.10.82 year).

This method is time-consuming, additionally, it has limited functionality.

The proposed invention is directed to a simplified method of manufacturing a die forms and expansion of their functionality, allowing cutting products.

This object is achieved by a method of manufacturing a die shape for cutting products by attaching to the base form of a metal loop that is executed on the configuration of the product, and the subsequent consolidation of its solidified filler, which in contrast to the prototype as the basis use a slab of hard magnetic material, on which is placed a drawing made on the configuration of the cut product lines which establish using magnetic force coupling the metal loop of the cutting lines, and the distance from the contour defined by the size of die form, install a metal casing, which solidified fill material thus to th die form is separated from the magnetic plate.

The height of the cutting edge of the circuit depending on the thickness of the cut item set in the range of 2-10 mm

Significant difference between the proposed method of manufacture of stamping molds for cutting products that improve the wear resistance of the cutting element, the durability of a stamp, to significantly reduce the complexity and cost of manufacture, is the method of fastening the cutting lines to the bottom of the stamp.

In the proposed method provides high accuracy observance of the sizes of harvested products, which is achieved by using, for example, laser processing methods grooves, in which are inserted with an interference fit, the cutting line. But the known laser processing methods are costly and complex, requiring special equipment. In addition, during operation of such stamps inevitably there is a loosening of the cutting lines in the grooves of the base form, which is excluded in die form, made by the proposed method.

Thus, the proposed set of essential features allows you to get a new above-mentioned properties.

The essence of the proposed invention is illustrated by the drawing, which shows: pH">

The method is as follows.

On the plate 1 is placed a drawing made on the configuration of the cut product, for example, on a sheet of paper. Then take a metal cutting line, bend them along the lines of the drawing, forming a loop 2, which is installed on this drawing. Magnetic adhesion forces acting at the same time, hold the loop on the plate 1. Then install on the same plate metal casing 3 at a distance from the contour defined by the required size of die form. It also uses a magnetic force of the clutch. Then it is filled with contour hardening material, for example epoxy resin, mixed with plasticizing substance. Leaves free cutting edge contour at height h=2-10 mm, which depends on the thickness of the cut item. After the hardening of the filler removed the formwork, and the resulting molded form is separated from the magnetic plate.

Obtained by the proposed method form with high accuracy can withstand the dimensions of the cut product is quite durable, cheap and convenient in operation.

1. A method of manufacturing a die shape for cutting products by joining what about the solidified filler, characterized in that as a reason to use a slab of hard magnetic material, on which is placed a drawing made on the configuration of the cut product lines which establish using magnetic force coupling the metal loop of the cutting lines, and the distance from the contour defined by the size of die form, install a metal casing, which solidified fill material so that it remains free software required for cutting products cutting edge contour, after which the formwork and the resulting molded form is separated from the magnetic plate.

2. The method according to p. 1, characterized in that the height of the cutting edge of the circuit depending on the thickness of the cut item set in the range of 2-10 mm

SUBSTANCE: invention relates to machine building and may be used for recess milling in the workpiece material for making parts. Recess in the part comprises angularly converging edges in the part angular area. During the recess milling, the angle cutter forms an enveloping surface, particularly a cylindrical surface with a side surface and an end surface. Angular area at first is carried out with the first orientation of the angle cutter corresponding to the longitudinal axis of the recess, using the section of the angle cutter making the side surface. Another option is formation of pointed angles in the second orientation of the angle cutter using the section which makes the end surface of the enveloping surface, the angular formation made between converging sections of the peripheral edges corresponds to junction between the end surface and the side surface. If necessary, a chamfer is formed directed across its longitudinal direction at the section of peripheral edge.

EFFECT: making parts with recess.
