Description

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for the separation of rolled metal into dimensional workpieces.

The purpose of the invention is to simplify the design of the device.

The drawing shows the proposed device, a General view.

The device comprises a support device 1. a movable plate 2, a breaker 3, a mechanism for moving the knife 4, containing a guide 5 mounted on a movable plate, a pusher 6s, a cam 7 mounted on a support device, a slider 8.

The device works as follows.

In the initial state of the device, the movable plate 2 is in the extreme position, the rod is inserted into the support device. During the working stroke, the plate 2 together with the bed 3, the guide 5 and the sliders 8 are lowered, the pusher 6 carries out the rolling of the knife 4. Having moved down by h (equal to the required depth of the concentrator), the half-poles begin to interact with

the inner wedge surface of the cam 7, therefore, under the action of the outer wedge surface of the pusher, the sliders are moved apart, and the insertion of the knife 4 is stopped. The angle of the kayin surface of the cam 7 relative to the vertical should not be less than the angle of inclination of the wedge surface of the pusher 6. With further movement of the plate 2 downwards, the breaker 3 breaks off the workpiece 10. During the return stroke, the plate together with the bed 3, the guide 5 and the sliders 8 return to their original state the The return of the pusher 6 (movement relative to the guide 5) is carried out under the action of a spring. Thereafter, the bar is fed into a step, and the cycle is repeated.

Adjusting the depth of the concentrator is carried out by changing the size of the knife exit from the pusher or by installing shims between the cam and the support device. To ensure the operability of the device, it is enough to have one slider; however, their symmetrical installation allows for a more rational distribution of forces in the structure.
