Device for continuous pressing of metals

The utility model relates to the processing of metals by pressure and can be used for the production of semi-finished products and products.

The closest technical solution is a device for continuous metal pressing, including two rolls, one of which is made with a stream, the other with a protrusion, forming a working gauge, the matrix 1 is installed at the output of which.

A disadvantage of the known device is the inability to adjust the distance between the rolls and the matrix, which often leads either to jamming of the rolls and the formation of scoring on their surface, or to the outflow of metal between the rolls and the matrix. In both cases, the process must be stopped.

The objective of the proposed utility model is to increase the reliability of the device by improving its design.

This object is achieved in that a device for continuous pressing of metals, including two rolls, one of which is made with a stream, and the other with a hood that form a working gauge, the matrix is installed at the output of it, is additionally equipped with an instrumental assembly consisting of a housing rigidly fixed on the bed, inside of which there is a matrix holder, with a matrix fixed on it, a clamping mechanism of coarse adjustment, consisting of a threaded sleeve resting on the matrix holder with its end surface a body, a flywheel mounted on a sleeve, a wedge-tight wedge mechanism of fine adjustment, consisting of a wedge entering the groove of the housing and contacting the working surfaces with a cutout in the matrix holder and the housing of the tool assembly. Between the matrix and the surface of the caliber rolls installed bronze liner.

Improving the design by installing the tool assembly and a bronze liner on the matrix allows you to adjust the gap between the rollers and the matrix, excluding jamming of the rollers, metal dropping between the rollers and the matrix and the formation of scoring on their surface, which increases the tool life and leads to uninterrupted operation of the device.

The proposed device is illustrated by drawings:

In FIG. 1 shows a General view of the device;

Figure 2 shows the matrix, with a fixed bronze insert.

The device comprises a roll 1 made with p) D1, a roll 2 with HIGH, forming a working gauge 3, at the output of which a matrix 4 is installed. The device is equipped with a tool assembly consisting of a housing 5, rigidly mounted on a frame 6. A matrix holder is located inside the housing 5 7, with the matrix fixed 4. The coarse adjustment clutch mechanism consists of a threaded sleeve 8, resting the end surface on the matrix holder 7, a flywheel 9 mounted on the sleeve 10, and a movable wedge fine adjustment mechanism, consisting th of the flywheel 11, the wedge 12 entering into the groove 13 of the housing 5 and contacting the working surfaces with a cutout 14 in the die 7 and the housing 5 of the tool unit. Between the matrix 4 and the surfaces of the rolls 1 and 2, a bronze insert 15 is installed.

The device operates as follows

The source material in the form of a rectangular billet is fed between the rotating rolls 1 and 2, forming a working gauge 3. The workpieces are crimped between the rollers 1 and 2, filling in gauge 3 and squeezed out into the hole of the die 4 installed at the outlet of gauge 3. Under pressure from the metal, die 4 moves away from the initial position, forming a gap between it and the rolls 1 and 2. The flywheel 9, rotating moves the threaded sleeve 10, which, resting on its end surface on the matrix holder 7, moves it and the matrix 4 in the direction of the rolls 1 and 2. For installation of wholesale mal gap between the rolls 1 and 2 and the die 4, a flywheel 11 driven wedge 12 which enters or exits the groove 13 in the die body 7 and CCRF worktops

on the walls of the matrix holder 7 makes it possible to increase or decrease the gap.

The proposed device due to precise adjustment allows you to avoid the penetration of metal between the rollers and the matrix, which increases the stability of the device, and the use of a bronze insert increases the tool life by 3-5 times.
