Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a forming spinning machine. Background Art

[0002] The spinning machine is a metal plastic forming machine tool. Its working principle is to fix the workpiece on a rotating table. While the circular turntable drives the workpiece to rotate, the spinning wheel applies pressure to the workpiece to cause continuous local deformation, thereby grinding and shaping its external shape.

[0003] An existing forming spinning machine (Announcement No.: CN220970510U) has at least the following disadvantages: the device starts the first hydraulic cylinder, and the telescopic shaft of the first hydraulic cylinder drives the fixed plate to move downward until the fixed plate fits with the upper surface of the workpiece, and then starts the first motor, and the output end of the first motor drives the disc to rotate, and the disc drives the workpiece to rotate. At the same time, the fixed plate and the first hydraulic cylinder rotate in the rotating assembly driven by the workpiece. This method can effectively solve the problem that the spinning machine in the prior art can only fix the workpiece with a hole in the middle and has a small range of use. However, the device can only adjust the height of the spinning device, and cannot adjust the pitch angle of the spinning device, so the applicable processing range is limited. In addition, the device uses multiple hydraulic cylinders to position the material, and the production cost is high. Utility Model Content
