Abstract

The invention relates to the processing of metals by pressure and can be used in the preparation. talting industry for low-waste, high-performance separation of long products into workpieces of regular geometric shape with smooth ends. The goal is to increase productivity and improve the quality of cooking. The bar 9 is fed through the holes in the guide sleeve 4 and the fixed knives 2 to the stop 4, the cross is clamped by the clip 5 and the cutting of the waste part 10 is carried out using a blade 8 with the blade 8 to produce a rolled section that is a multiple of the length of the billet. The working part of the blade knife 8 is made in the form of an angular notch with a radius transition at the apex, so that when cutting waste in the area under the blade knife, the stress is compressed completely and compression is separated by plastic shear. The metal then moves both in the radial and axial directions, creating axial compression in the cut section of the rolling stock. Under these conditions, the rolled section enclosed between the anvil 3 and the blade knife 8 is cut into short blanks. 2 Il. in g Yu SO QD Yu

Description

" .one .

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for the separation of rods into blanks.

The purpose of the invention is to increase the productivity of the device for the separation of rods and to improve the quality of the obtained blanks.

FIG. I shows a device for dividing the rods at the moment I completes the cutting of the waste with a blade knife; FIG. 2 - blade knife.

I The device for separating the rods I consists of the base 1, on which the fixed knives 2, the front stop 3, the guide bushing 4 and the transverse clamp: 5 rods and the upper plate 6 with fixed on her movable knives 7 and blade knife 8.

The device is mounted on a press and operates as follows.

The bar 9 is fed through a hole in the guide sleeve 4 into the fixed knives 2 up to the front stop 3. A transverse bar clip is formed by the clip 5 (the clamp drive is not shown). When the press ram is lowered down, first with a blade knife 8, the cutting part of the GO is cut out, section I of the rod is cut 11 in length, I times the length of the workpiece 1 ,. When you cut: the waste part 10, a part of the metal under the influence of the blade knife 8 is displaced in the axial direction, which leads to a decrease in the waste volume and the axial compression in the cut section II. At the end of the cutting of the waste part, the blade knife acts as a predetermined stop that holds cut section 11 in the state of axial compression. Upon further downward movement of the press ram, section 1I is cut into short blanks under axial compression conditions. At the completion of the cutting, the front stop 3 is retracted and the blanks are removed from the working area of the device.
