Description

The invention relates to the processing of metals by pressure, in particular to the stamping of parts from pipes, and can be used in the aviation and related industries.

The aim of the invention is the expansion of technological capabilities by improving lubrication conditions and improving the reliability of the design of the device.

The drawing shows the diagram of the device (on the left - the initial position; on the right - the final moment of distribution).

A device for distributing billets includes a hollow punch 1 with a system of grooves a for supplying lubricant, which is mounted on the base 2, a rigidly fixed guide 3, a piston with a rod 4, made hollow and mounted with the possibility of mixing along the guide 3. In the profiled The piston is provided with a system of channels b with valves 5 coaxial with the main axis of the device.

The device also contains a clamp 6 of the workpiece in contact with the piston rod 4 during the process. The workpiece retainer has a channel system in to supply refrigerant. The preform 7 is heated by the inductor 8 during the deformation process.

The device works as follows.

Before operation, for example, graphite grease is fed through channel 9 in guide 3 into oil cavity B formed by guide 3 and piston. The billet 7 is put on the piston rod 4, mounted on the punch and pressed from above

sator 6, which centers the workpiece. When the lock moves down, the workpiece 7, together with the piston rod 4, moves along the guide 3 downwards. In this case, the workpiece is distributed, and graphite grease from cavity B under pressure through the system of channels and with opening valves 5 in the piston into the cavity A formed by the punch and stem piston. Next, the grease in the grooves and in the punch falls under the workpiece.
