(54) DEVICE FOR SPRINGING CYLINDRICAL SPRINGS

The invention relates to mechanical engineering.

A device for winding coil springs is known, comprising a caliper, a hydraulic motor and a drive for rotating the mandrel tl 3.

A disadvantage of the known device is the complexity of the process of manufacturing the springs;

Closest to the present invention is a winding device for cnclrnc cvsk springs, comprising a caliper mounted on a frame that can be moved by means of a hydraulic cylinder, controlled by a valve, a mandrel, an axle, a ring, a connecting shank-lip and a rotation drive of the mandrel 2.

A disadvantage of the known device is the considerable labor intensity of manufacturing and the complexity of the process of manufacturing springs,

The purpose of the invention is to reduce the labor intensity of manufacturing and simplify the process of manufacturing cylindrical springs from blanks heated to 1000-1200C.

The goal is achieved by the fact that, in the known device for livelihood, ki cylindrical springs containing

,, axis, ring and connecting shank-floc, mandrel contains two segments with a gap between them.

The drawing shows the device, 6 (% view in two projections.

The device has two cylindrical segments 1, the shape of a cylindrical plate, with a gap S. One end of the mandrel is with the help of axis 2 on the hinge with a shank-flange 3, on which there is a stop 4. At the other end of the mandrel there is a safety ring 5. to set the diameter of the mandrel.

The device works as follows. .

A flux shank 3 of the device is installed in the chuck of the machine. Center tailstock of mandrel segment 1

20 are pulled apart until the safety ring 5 has been secured.

With the help of the speeding box of the turning machine, the springs are chosen with the need for springs k Turns on the spindle with the need-. 2 turns and at the same time serves the caliper of the workpiece for winding the ukha {1Y in a hot condition, the temperature of which is up to 1000-1200 ° C. To remove the finished spring with the required spacing from the mandrel 1, the tailstock with the center moves to the right, with this creates a gap between the finished spring and the mandrel 1, and the ready spring is removed with the necessary pitch. The proposed device makes it possible to reduce the laboriousness at the production of a research institute of a compression spring and expansion in the state of the workpiece and to improve its quality and reliability.
