The purpose of the invention is the expansion of technological capabilities through the processing of materials of different thickness. Ptamp contains in the movable part of the plate (P) 1 and 4. On P 1 there are installed punches (PI) 3 for punching. At P4, PN 5 is installed for forming recesses. P1 and 4 are interconnected by wedges 7 and 8 with openings of a thread of the same name, a pin 9 connecting them and 10,11,12,13. In the fixed part of the installed P19 with a matrix 2P. When working stroke, punching of the holes PN 3 occurs first, and then the recesses of the PN5 are formed.

Description

The invention relates to the processing of metals by pressure, in particular to stamps for processing sheet material.

The purpose of the invention is the expansion of technological capabilities through the processing of materials of different thickness.

FIG. 1 shows a stamp, a general view; in fig. 2 - the same plan view; in fig. 3 is a view along arrow A in FIG. in fig. 4 - section BB on Lig.1.

The stamp contains in the movable part a plate 1 with a shank 2 and punches 3 for punching and an additional plate 4 with punches 5 for forming recesses covering the punches 3. On the plate 1 there is also a plug 6

for cutting and bending. Plates 1 and 4 are interconnected by means of organizing a relative approach in the form of wedges 7 and 8, which are in contact with plates 1 and 4 and have threaded holes, one with the right, the other with left-handed, studs 9 with sections of the opposite thread, wedges 7 and 8, and so on 10,11,12,13,14,15, 16,17, pivotally connected with wedges 7 and 8 and plates 1 and 4. The file has locknuts 18.

In the fixed part of the stamp, a plate 19 is installed with a die 20 for punching and cutting, a die 21 for bending. The plate 19 also contains the puller 22, the ejector 23 and the stop 24.

Position 25 marked the workpiece, 26 - detail.

The stamp works as follows.

Before starting work, the required mutual arrangement of punches 3 and punches 5 is established. To do this, release the lock nuts T8 and rotate the stud 9, wedges 7 and 8 are pulled together or diluted, which changes the mutual arrangement of plates 1 and 4} carrying punches 3 and 5. Then lock-nuts 1– are tightened.

During the working stroke, holes are punched at the first position of the punch by punches 3 and the recesses are molded by punches 5. Then, at the next position, when the blank (strip) 25 is fed to the stop 24, the piece and the flexible part 26 are removed and removed by the ejector 23.

When the material thickness is changed or after re-grinding of the punches 3, the relative position of the punches 3 and 5 is changed by the previously specified adjustment.

The invention allows to expand the technological capabilities of the stamp.

Claims (1)

Claim A combined stamp of combined action, comprising in the movable part a plate with a punch punch rigidly fixed on it, an additional plate with a punch rigidly mounted on it to form a recess covering the punch punch, and means for limiting the relative proximity of the plates located between them with the possibility of interaction, and in the fixed part containing a matrix, characterized in that, in order to expand technological capabilities by processing materials of various thicknesses, the ogre The relative rapprochement of the plates is made in the form of two wedges, in one of which a hole with a right-hand thread is made, in the other - with a left, each of which is located with the possibility of interaction with plates, rods that articulate each wedge with each plate and studs with the right and left-hand thread connecting the wedges.
