Abstract

Use: metal forming. In a turret punch press with two turrets 3 and 4, the slider 1 is placed in the head 3. With the slider 1, punch holders 9 are connected and on each concentrically with its tail part there is a pressure ring 15. Punch holders 10 and puller clamps 11 are placed. When the working stroke of the slide 1, the punch 10 is in contact with the workpiece 20. The puller 11 stops. The ring 15 comes into contact with the spring-loaded rods 17. They abut against the pushers 18, compress the springs 19 and transmit their forces through the ring 15. the guiding fingers 13 and the puller 11 to the workpiece 20. 1 sludge. L I O 00 o y

The invention relates to the processing of metal pressures, in particular, to the design of a turret of a coordinate-turret punching press.

A punching revolver press is known, containing a slider, a turret with punch blocks, a puller, made in the form of a sleeve, in which it is installed with possible interaction with the elastic element 10 with a wanson fixed in it.

The disadvantage of this press is that the number of plugging joints is increased in the design (a disk hub of a pinch-puller-punch holder), thereby increasing the total gap between the tools, which worsens the conditions of their work.

Also known is a punching revolver press containing a slider, a turret head in which a punch holder with a punch fixed in its lower part, a clamp-remover, an engaging punch, and spring-loaded rods supported on the stripper , and pressure ring, as well as containing a turret with dies placed in it.30

The disadvantage of this press is that the punching tool is made in the form of a three-block construction (punch with punch, pressure remover, die), which increases the time 35 of its changeover.

The purpose of the invention is to reduce the time for readjustment of the stamping tool.

The goal is achieved by the fact that a 40 punching turret press containing a crawler, two turrets, dies placed in one of them, a punch holder associated with the crawler, placed in another revolver head 45 and a bearing punch and a clamp-remover, and also containing guide pins, elastic elements, pressure ring and spring-loaded rods connecting the puller with a slide, the guide ring 50 is mounted on the punch holder concentrically with its tail part, in the punch holder the through holes are in place, and the guide fingers and elastic elements are placed in them. 55

The drawing schematically shows the proposed press.

Punching turret press contains a slider 1, placed in the bore of the bed 2, two turrets 3 and 4. In

lower revolving head 4 along the radius placed matrix holders 5 with dies, and in the bores of the disk of the upper revolving head 3 punch blocks 7, connected to the slider 1 by means of a T-shaped shank. Outside of the slider 1, the punching blocks 7 rest on the supporting disk 8.

The punch blocks 7 consist of the punch holder 9, the punch 10, the pressing puller 11 with the interchangeable insert 12, the guide fingers 13 arranged in a circle with elastic elements 14, the pressure ring 15 with the key 16.

In the slider 1, spring-loaded rods 17 are placed in contact with elastic elements consisting of pushers 18 and springs 19.

The workpiece 20 is located between the top 3 and bottom 4 turrets,

The device works as follows.

In the initial position, the slider 1 is in the upper dead center (TDC), and between the punch block 7 and the die 6 there is a gap in which the workpiece 20 is located, while the cutting edge of the punch 10 is slightly higher than the interchangeable insert 12 of the puller 11.

When the slider 1 makes a working stroke, the punch block 7 moves down to meet with the workpiece 20. From this point on, the puller 11 stops moving, pressing the workpiece 20 to the matrix b, and the punch 10 continues downward movement and punches the hole in the workpiece 20.

From the moment the puller 11 stops, the pressure ring 15 comes into contact With spring-loaded rods 17, which, pressing against the pusher 18, compress the springs 19. The force of the springs 19 is transmitted to the workpiece 20 through the pressure ring 15 and guide rings 13, the puller 11 with an insert 12. The preform 20 is in the pressed state until the punch 10 is completely out of it. When the TDC is reached, the slider 1 stops.

8, the proposed design reduces the tool changeover time by replacing the three-block design of the punch block with a double-block (punch holder with punch and clamp-remover, die).
