Description

one

The invention relates to the cold working of metals by pressure, in particular to devices for processing tubular parts.

The purpose of the invention is to expand the technological capabilities of the device by allowing the ends of tubular parts to be rolled.

The drawing shows the proposed device.

The device comprises a matrix 2 mounted in the housing 1 for rotation, and a mandrel 4 mounted on a vertical spindle 3 of the machine for rotation and reciprocating relative to the housing 1, while at the end of the mandrel 4 facing the matrix 2 and on the working the surface of the matrix 2 is made of shaped annular grooves 5 for accommodating the ends of the tubular parts 6, and the axis of the axis of the matrix 2 is located beneath the fragile surface. to the axis of rotation of the mandrel 4. In the upper part of the die 2 there is an annular shoulder 7, with which it rests on the upper bearing 8, on the lower part of the die 2 there is a thread on which the nut is screwed

9, abutting against the bottom bearing

10. Between the bearings 8 and 10, spacer sleeve 11 is installed. On top, the body 1 is closed by a cover 12, which is fastened to the body 1 with screws 13. In the lower part, the body 1 has a flange with grooves for securing; the body 1 on the frame (not shown),

The device works as follows.

The tubular part 6 is loaded into the working area of the device by any known method, so that the left part of its lower end enters the profile annular groove 5 of the matrix 2, and the plane of the lower section

was tilted to the upper plane of the matrix 2 at an angle of C / 2. The spindle 3 of the machine with the mandrel 4 moves down to the stop of its profile ring 5th groove 5 in the left part of the upper end of the part 6. The spindle 3 actuates. At the same time, it rotates the mandrel 4, and the latter rotates the part 6 about its axis. Detail 6 for

10, the friction force account synchronously rotates the matrix 2. Thus, as they press the outer and inner edges of the ends of the part 6 under the pressure of the plane of the profile annular grooves 5, they are rolled

15 and take the size and shape of these grooves. After obtaining the required profile of the ends of the part 6, the mandrel 4 with the help of the spindle 3 is retracted to the initial position, freeing the detal 6 that is moving, for unloading. Then the cycle is repeated.

Compared with the known, the proposed device provides wider technological capabilities.
