DEVICE FOR

MANUFACTURING

CORRUGATED

lanes

The invention relates to the processing of metals by pressure.

Known devices for making corrugated strips are a stamp that has forming and pressure punches attached to the upper plate and a detachable die fixed to the lower plate, in which one part can be displaced in the feed direction.

The purpose of the invention is to improve the accuracy of the corrugations obtained.

This is achieved by the fact that the proposed device is equipped with a preliminary corrugation punch mounted together with a clamping punch on one side of the forming punch on a horizontally movable carriage springed to the upper plate, and mounted on the other side of the punch and spring-loaded to the upper plate with a calibrating punch and forming punch Corrugated vertices of elastic material. At the same time, the movable part of the die has pre-molding, pressing and molding of one side of the corrugation and is connected via columns to the carriage with the possibility of joint movement and with the braking unit provided on the bottom plate. The fixed part of the matrix has areas for molding the other side of the corrugation, calibrating and molding the corrugation lip. Knot

braking is made in the form of a rod mounted in the movable part of the matrix with the possibility of vertical movement and interacting with the bar fixed

on the bottom plate.

FIG. 1 shows a device in cross section; in fig. 2 - sectional brake mechanism; in fig. 3 is a diagram of the device at the initial moment; in fig. 4 - device, view

from above.

The strip is placed on the tray I, so that its end is on the edge a (see Fig. 3) of the die 2 and the first punch is struck. It consists of a punch 3 pre-forming clamp 4, a forming punch 5, a calibrating punch 6 and a punch 7 of the corrugation. A preliminary corrugation formed on the strip is installed in the cavity b of the matrix 2 and a second punch is struck. The second preformed corrugation is installed in the socket b and the next blow is made with a collective punch, in which the matrix 2 is compressed

the first preliminary corrugation and, falling under the punch 5, is finally formed in the nest in the dies formed by 8 k. 2. At the same time, the third preliminary corrugation is formed in the strip. Moreover, the strip at the time of forming is always pressed in the slot b by the clamp

4. Advance the strip by one pitch, the first formed corrugation, falls into the socket r of the matrix 8, is calibrated by the punch 6. With the next movement of the tape to the pitch, the first corrugation enters the socket n, in which the punch 7 forms stiffness bulges.

Then, after each stroke of the collecting punch, the strip advances a step and is fixed by the formed corrugation in the socket of the city.

The preformed punch 3 and the pressing 4 are fixedly mounted on the carriage 9, which moves along the roller guide 10 together with the die 2 fixed on the slide //, from the wedge pushers 12 mounted on the upper plate 13.

The forming punch 5 is fixedly mounted on the top plate 13. The sizing 6 and the elastic punch forming the tops of the corrugations 7 are fixedly mounted on the strap 14, which, like the carriage 9, is spring-loaded in relation to the top plate.

The braking unit (see Fig. 2) is designed for braking the movable matrix for the period of the punch 3 coming out and pressing 4 out of the formed corrugation zone. The braking assembly consists of a plaque 14 located on the bottom plate 15, and a rod 16, which, resting against the bar 14, brakes the matrix 2. The rod 16 moves in the sleeve 17 from the spring 18, and the sleeve 17 is fixed and slides in the hole of the slider 11 under the action of the spring 19.

The upper extreme positions of the sleeve 17 are limited by the stop bar 20, which rests against the shoulder of the removed bald faces on the sleeve 17. The springs 18 and 19 abut against the plug 21 screwed into the sleeve 17. At the upper end of this plug 21 as the assembly punch is pressed down, the stop 22 is pressed down. located on the top plate 13, and moves the sleeve 17 down. The spring 18 presses against the rod 16 and also forces it to move downward against the stop into the upper plane of the bar 14. As soon as the matrix 2 moves to the leftmost position, the lower rod 16 will come off the upper plane of the bar 14 and lock the matrix in its initial position.
