Description

(54) STAMP FOR PROCESSING PROFILES

one

The invention relates to the processing of metals by pressure, in particular, to universal dies for processing profiles such as angles and tavras.

A stamp is known for punching holes in hollow parts, containing a matrix mounted on the bottom plate and a punch mounted on the top plate and a clamp that is spring-loaded to the matrix 1.

The disadvantage of this stamp is that the clamp, already in contact with the workpiece while pressing it against the die, continues the downward movement necessary for punching the hole for some time.

Closest to the proposed stamp for processing profiles such as angles and t-shaped, containing a punch and a die for punching holes, installed respectively on the upper and lower plates, as well as a pressure device that interacts with the profile wall, presses the profile to the support mounted on the lower plate, and made in the form of a slider consisting of a body and 1 × 1 movably connected to it without the other element of the handpiece with its movement limiter relative to the body of the slider and connected with the upper

plate by the transforming mechanism of movement 2.

In this stamp, Lolzushka is installed on the bottom plate, which makes it impossible to automate the installation of a profile to a working position.

The purpose of the invention is to provide the possibility of automating the installation of a profile to a working position.

This goal is achieved by the fact that, in a strain for processing profiles such as angles and tees, containing a punch and a matrix for shaking a hole, mounted respectively on the top and bottom plate, the adjoining device, which interacts with the pressure wall, attaches the profile to the support mounted on the bottom plate and made in the form of a slider consisting of a body and

20 movably connected with it through an elastic element of the tip with a limiter of its movement relative to the body of the slider and connected with the upper plate by a transforming movement mechanism;

25 the transforming mechanism for moving the slider is made in the form of a glass mounted on the top plate, having two through-mutually perpendicular holes in the walls, one of which, with

30 axis perpendicular to the direction of displacement of the slider, made oval, with a larger axis of the oval, parallel to the direction of movement of the slider, and the stop, movably installed in the cavity of the glass with the ability to interact with the lower plate, slew spring, the force of which is set to the bottom, and having grooves, one of which is profiled, slider is installed in the holes of the walls of the glass and in the groove of the stop and is provided with a lip, located in the oval holes of the walls of the glass and looking at the sliding action | .

The piasAiep of the oval hole of the glass in the direction of the greater axis of the oval ino is at least equal to the distance between the extreme points of the pressure groove of the abutment in the same direction.

The limiter for moving the tip of a Lazulka is made in the form of a pin, mounted in the case of the slide, perpendicular to its axis, and the tip has a slot, and a pin is located in this slot.

FIG. 1 shows the general view of the 1Mpa at the end of the working stroke; in fig. 2 - section A-A of FIG. one; in fig. 3 - the clamping device with the retracted slide.

The stamp contains a bottom plate 1 on which a support 2, M1, 3, 3, a hard puller 4 and guides 5 are installed, and an upper plate 6 on which a ring holder 7 with punches S and 9 is installed and a clamping device containing a cup 10, an emphasis II , spring 12 and crawler 13.

In glass 10, through holes 14 and 15 are made. Hole 15 is oval.

Unnor 11 is made with grooves 16 and 17. The groove 17 is profile.

The slider 13 consists of a body 18 in which 19 and a handpiece 20 are mounted, which is connected to the body 18 by a limiter 21 and elastic elements 22.

The body 18 of the slider 13 is installed at the same time in the holes 14 and in the groove 16. The finger 19 of the body r is positioned adnodely in the holes 15 and in the groove 17.

The stamp works as follows. The workpiece 23 in the direction of 5 goes up to the stop in the puller 4. When the plate b is lowered, the stop 11 reaches the plate 1 and stops, la cup 10, continuing downward movement, moves the slider 13 towards the aperture 23, pressing it to the puller 4, due to displacements P1altsa 19 along the groove 17 of the stop M and in the oval hole 15 of the cup 10.

The elastic element 22 when clamping compensates for the errors of the workpiece.

With further lowering of the slab, the punches 8 and 9 perform their functions.

When lifting the plate 6, the spring 12 moves the stop 11 up, and for these reasons, the slide 13 moves back by an amount / defined by the profile of the groove 17 and the size of the large size of the oval hole 15.

At the extreme upper position. The plates 6 are free to remove the finished work piece 23 and install a new one.

The implementation of the invention will automate the process and ease labor conditions.
