Abstract

The invention relates to the processing of metals by pressure and can be used for cutting round steel into chamfered blanks. The purpose of the invention is to increase the productivity of a device for separating rolled products of circular cross section. The tangential cutter 6 cuts a groove in the car, the conical surfaces of which form chamfers on the cut blanks. After the last cutting point of the profile of the cutter 6 comes out of contact with the car, the radial cutter 4 enters the work, which in the bottom of the already grooved groove forms an additional voltage concentrator groove. Simultaneously with the cutter 4, breaking rollers come into operation, which turn down the cut part of the rolled stock. After the workpiece has been separated, the slider 3 is retracted: the segments are returned to the initial position and the cycle is repeated to separate the next workpiece. The angle in the plan at the apex of the radial cutter is 60- 90. 1 Cp f-ly 4 Il. / f- with (L OO GS with to ate CX) srig.1 IT

Description

11323258

The invention relates to the processing of metals by pressure and can be used in the blank production of machine-building enterprises for the separation of rolled products of round cross-section.

The purpose of the invention is to increase the productivity of the device for the separation of rolled products of circular cross section, JO

Fig. 1 shows a device for the separation of rolled metal, plan view; in fig. 2 is a section A-A in FIG. I; FIG. 3 is a section BB in FIG. 2; on

The split rolling 2 is fastened with the clamp mechanism 1, after which the rolling clamp mechanism is rotated. Then the slider 3 is moved towards the rental 2, Tangential cutter 6 cuts through the groove grooves, the conical surfaces of which form chamfers on the cut blanks. After the last cutting point prof. Of the cutter 6 comes out of contact with the car, a radial cutter 4 enters the work, which in the bottom of the already grooved groove forms an additional groove - the concentrator

FIG. 4 - end face profile of cut-off-15 voltages. Simultaneously with the cutter 4 in cooking ,,

The rolling separation device comprises a rolling clamp mechanism 1, a driving slider 3, a radial cutter 4 and breaking rollers 5 mounted on a slider 3, In addition, a cutter b is mounted on the slider, which moves tangentially along the slider. with respect to the section of rolled. The tangential cutter 6 is mounted in such a way that the distance L in the direction of the working movement of the slide from the top of the radial cutter to the last cutting point of the tangential cutter profile is not less than half the diameter d of the weakened groove of the rolled section. The angle at the vertex in terms of the radial cutter 4 is made in the range of 60-90, and the radius of rounding of its vertex g is 0.3-0.5 mm. The angle at the apex in terms of the tangential cutter 6 is made in accordance with the specified dimensions of the chamfers on the plates of the workpiece to be separated.

The device works as follows.

Work comes breaking rollers 5, which bend the notched part of the car. After a small introduction of the cutter 4, the movement of the slide is stopped and after a certain number of revolutions, the workpiece is separated. The slider 3 is retracted to its original position, after which the cycle of segments is repeated to separate the next billet.

Claims (2)

1. A device for dividing rolled round cross section into chamfered workpieces, comprising a rolling clamp mechanism and a drive slider with a radial cutter mounted on it and rollers bending, which is equipped with a tangential cutter mounted on the slider . 2. The device according to claim 1, characterized in that the angle in the plan at the apex of the radial cutter is 60-90 °. The split rolling 2 is fastened with the clamp mechanism 1, after which the rolling clamp mechanism is rotated. Then the slider 3 is moved towards the rental 2, Tangential cutter 6 cuts through the groove grooves, the conical surfaces of which form chamfers on the cut blanks. After the last cutting point prof.
