Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotary forging machines, in particular to a rotary forging machine for precision parts processing. Background Art
[0002] Rotary forging, also known as radial forging, is a long shaft rolling forming process. It strikes the workpiece with high-frequency radial reciprocating motion. The workpiece rotates and moves axially. Under the impact of the hammer head, the workpiece is radially compressed and length-extended.
[0003] The existing patent application number is: 202222136131.5, and the patent name is: A precision parts processing rotary forging machine; the device can realize water spray cooling of the completed shaft parts by arranging a water storage box, an L-shaped rod, a vertical plate, a water pump, a water suction pipe, a water outlet pipe and a nozzle. By arranging a suction fan, a suction pipe, a suction hood and an air outlet pipe, when water is sprayed on the surface of the high-temperature shaft parts, a large amount of water vapor will be pumped into the water storage tank, which can save water resources. This cooling method has a high cooling efficiency, and the staff will not be scalded when taking it. When the device clamps and fixes the shaft parts, it clamps the shaft rod through the cooperation of two relative clamps and anti-slip rubber pads. The operation is convenient and quick, and the shaft parts can also be centered.
[0004] This solution has the following defects:
[0005] The device uses a bidirectional screw, a motor and a guide rod as the power to drive the two clamps to move relative to each other. Since the bidirectional screw and the guide rod are located in the middle of the clamp, the length of the two relative clamps for the shaft rod parts is fixed. After searching, it can be found that during the processing of the shaft rod parts, since the clamping distance at one end is shorter, it is easy to cause the axis centers of the two ends to be not in the same straight line, which can easily cause errors in the processing of the shaft rod parts.
