Abstract

SUMMARY OF THE INVENTION: The stamp of a horizontal forging machine comprises a movable and fixed matrix with a closed molding creek. The creek is formed by the surfaces of the punch and inserts for trimming the end burr. The stamp is equipped with a cutting creek. The cutting stream contains a cone-shaped punch and inserts. The corresponding surfaces of the molding punch and inserts are made inclined with an inclination angle of 5-7 °. 1 zpf-ly, 1 silt

Description

The invention relates to the processing of metals by pressure and can be used in and / for stamping.

A closed landing stamp is known, consisting of matrices, poods of sleep and inserts, in (forgings are stamped with a face /; sits -m A face burr grinds-, "TJ r-ikdg.ch stone or on a mechanical- |, tznkeh during processing cutting, or

   it is called on the forging equipment, for the subsequent removal of cutting.

A disadvantage of such a stamp is the increased laboriousness of producing forgings associated with deburring on other equipment.

 The technical result obtained by using the invention lies in the possibility of trimming the end burr directly in the die of a horizontal forging machine.

The indicated result is achieved by that. The штамп stamp containing the movable and non т 1 «« «г матрицы die with a closed forming creek formed by the surfaces and / and ansone and inserts is equipped with a trimming p -: rye with a cone-shaped punch for sequential bending and trimming of the end burr, and the corresponding on top of the .locni molding punch and inserts, inclined at an angle of 5, .. 7 °.

The drawing shows the right part of the w 1amp with punches and inserts.

The stamp consists of a fixed 1 and a movable matrix, punches 2 and 3 and inserts 4 and 5.

The stamp works as follows.

Claims (1)

1. STAMP OF A HORIZONTAL FORGING MACHINE., Comprising a movable and fixed matrix with a closed molding creek formed by the working surfaces of the punch and inserts, characterized in that. that it is equipped with an edged stream with the corresponding punch and insert, while an edged 5 YU fifteen 0 fifty t 5 0 5 The workpiece 6 is placed in the matrix 1 and the insert 4 and clamped by a movable matrix, with the movement of the punch 2, deformation of the workpiece begins. The gap between the punch and the molding insert 4 is selected in the same way as in conventional punching with end burrs. Parts of the inner surface of the insert 4 and the corresponding outer surface of the punch 2 are made conical with a surface angle of 5 ... 7 °. In this way, the end burr 7 is conical. The stamped forgings with a burr are transferred to the trim insert 6. The burr is trimmed by a punch 3. The trimming punch 3 is cone-shaped, the angle of inclination of the cone is 45 °. When the conical surface of the punch comes into contact with the inner surface of the end burr, the burr is bent; during the further course of the punch, the burr is cut off. In the event that part of the burr is not trimmed, it is stamped with the end part of the punch. The use of a die design will reduce the cost of forgings by freeing up additional equipment necessary to remove the end burr and use normal precision for stamping. (56) Storozhev M.V. et al.
