Abstract

The invention relates to the processing of metals by pressure, more specifically, to devices for face rolling of workpieces. The purpose of the invention is to increase productivity and increase reliability. The device comprises a head 2 mounted on the frame 1 with a 3 rotation drive, a hollow spindle (Ø) 6 located in it, a die 13 and an ejector 7. as well as a head with idle rolls 23. The head 2 is axially movable. The ejector 7 is made in the form of a spring-loaded stem, passing inside the hollow Ø 6 and cooperating on the one side with the workpiece 9, and on the other with the movable stop 10. The device is equipped with a friction coupling 14 and a brake 20 mounted on the floor Ø 6. The latter is spring-loaded is movable in the axial direction. Item 9 to be rolled is installed in the matrix 13 and head 2 rises to the roll roll 23. 1 sludge.

The invention relates to the processing of metals by pressure, in particular to devices for face rolling of axisymmetric products.

The purpose of the invention is to increase productivity and increase reliability.

The drawing shows the device, General view.

The device for face rolling of axisymmetric products comprises a frame 1, on which a head 2 with a rotation drive 3 is disposed, having a possibility of movement in the axial direction from the drive 4.

In the case of the head 2, on roller radial bearings 5 there is a hollow spindle 6, inside which the ejector 7 is placed, spring loaded 8 and cooperating on the one hand with the workpiece 9, and on the other hand with the stop 10. The latter can move in the guides 11 from the pneumatic - cylinder 12. For mounting the workpiece at the end of the hollow spindle 6 there is a matrix 13.

To transfer the rotation from the actuator 3 to the spindle 6, there is a friction clutch, which consists of a sleeve 14 connected via a key 15 with a hollow spindle 6, a gear wheel 16, freely mounted on the sleeve 14, at the ends of which the friction linings 17 of the support ring 18 are attached with a hollow spindle 6 key 15, springs 19, interacting with one end with the sleeve 14, and the other with the stop ring 18.

To stop the rotation of the spindle 6, it is equipped with a brake consisting of a brake disc 20 rigidly fixed on the hollow spindle 6 and a brake flange 21 installed with a gap relative to the brake disc 20 and rigidly fixed on the head housing 2. On the base 1 there is also a head 22 with a single roll roll 23.

The device works as follows.

The part 9 to be rolled is inserted into the matrix 13 fixed in the hollow spindle 6. The drive for moving the head 2 is turned on, and moving to the right, it lifts the part 9 to the rolling roll 23. The force of the rolling acting on the workpiece 9 is transferred to the hollow the spindle 6 and displaces it to the left along the rollers of the radial bearings 5, while the hollow spindle 6 with its shoulder presses the constantly rotating gear 16 with the friction linings 17 to the stop ring 18 connected by a key 15

with a hollow spindle 6. Thus, the rotation from the actuator 3 is transmitted to the spindle 6 and the workpiece 9.

At the same time, the brake disc

20 moves away from the brake flange 21 and the spindle 6 is released. Rolling occurs, and the greater the force of rolling, the greater the transmitted torque.

After the rolling is completed, the head 2 with the workpiece 9 moves to the left, moves away from the roll 23, the rolling force disappears, the springs 19 through the sleeve 14 displace the spindle 6 to the right, releasing the gear wheel 16, the rotational transmission to the spindle 6 stops, simultaneously rotating with the spindle 6 brake the disk 20 is pressed against the fixed brake flange 21 and the rotation of the spindle 6 ceases instantly.

The head 2 continues to move to the left, while the ejector 7, which is located inside the hollow spindle 6, abuts against the stop 10,

stops and, compressing the spring 8. pushes the finished part out of the matrix 13, continuing to move with the head 2. Then the head 2 stops, the pneumatic cylinder 12 and the stop 10,

moving downward along the guides 11, releases the ejector 7. The latter, under the action of the spring 8, moves to the left, freeing up space in the die for mounting the next part to be rolled.

The work cycle is terminated.
