SU916240A1 - Method of producing male and female dies for die assembly - Google Patents

Description

The invention relates to the manufacture of stamps.

Known methods of fabricating the punch and die to die, including the installation of the matrix (the punch) on the drive end and a divider ⁵ pos- been consistent processing of each groove of one base element divider [1].

The disadvantage of the known ways; ·. Their inadequate accuracy of the mirror matrix punch is insufficient.

The purpose of the invention is the provision of high precision mirror match the punch matrix.

To achieve the goal after processing and storing the finished die (punch on), the punch blank (die) is installed, to the end face of the dividing dis-20 ka, opposite to the fixing face of the die (punch), while marking the first groove on both blanks for their exact assembly,

FIG. 1 shows a device for carrying out the method; in figure 2 ^; , 'view along arrow A in FIG. one.

The device consists of a PLATE 1, made with an inclination, into which thickening 2 is freely inserted a finger 3 with a sleeve 4 mounted on it. A separating disk 5 with tapered holes 6 is installed on the board, and a workpiece 7. The initial position of the separating disk 5 is fixed by inserting a clamp rod 8 9 into that conical opening 6 of the dividing disk 5, which is marked by risks 10. The dividing disk 5 and the workpiece 7 are connected to each other by means of bolts 11 and with a finger 3 “by means of a nut 12.

Board 1 is installed on a conventional milling machine (not shown) with a horizontally moving cutter 13.

The method is as follows.

In the initial position of the dividing disk 5 in the workpiece 7 using

3 91

The mills 13 perform the first groove, which is marked and the bottom of which, due to the inclination of the board, is tilted to the end of the workpiece at the same angle, although during machining the milling cutter moves horizontally.

Then the rod 8 of the retainer 9 is removed from the hole 6 with the risks 10, turn the disk 5 with the workpiece 7 around the finger 3 to the next hole, about 6, not marked by the risks, enter the rod 8 into it and mill the second groove in the workpiece 7.

Then this operation is repeated in that. the same sequence, prior to the production of 15 all the slots in the blank, after which the bolts 11 and the nut 12 are unscrewed, and the finished punch is removed.

Next, the separating disk 5 is turned over to the other end, connected with 20 bolts 11 and a nut 12 with a new billet 7, and again the pin 8 of the retainer 9 is inserted into the hole 6, marked by risks 10.

E1

Then, similarly, the cutter 12 in the workpiece performs a predetermined number of slots and a matrix is obtained.

This ensures high accuracy of the mirror matching of the grooves of the punch and die, since the available sources (tolerances) of the location of the hole 6 in the separator

disk 5 around the circle relative to each other are transferred in the same way: on the punch, and on the matrix by fixing the initial position of the dividing disc and turning it to the other end after the manufacture of the punch.

Claims (1)

Claim A method of manufacturing a punch and die for a stamp, including installing a die (punch) on the end of a separating disc and sequential processing of each groove from one basic dividing element, characterized in that, in order to ensure high accuracy of the mirror match of the punch to the die, after processing and removing the finished die (punch) billet punch (matrix) set to the end of the separating disc, the opposite end of the mounting matrix (punch), while marking the first groove on both blanks for them exactly assembly.
