Description

Technical Field

[0001] The invention relates to the technical field of forging machines, in particular to a clamping device for a forging table of a forging machine. Background Art

[0002] A forging machine is a machine that uses hammering and other methods to make metal materials in a plastic state become workpieces with a certain shape and size and change their physical properties. The forging hammer used in a forging machine is very similar to a press machine, especially a forging press, in terms of processing performance. However, as the forging hammer of the former, the reaction force generated by the processing is not borne by the bed, but by the foundation of the machine, which is fundamentally different from the latter press.

[0003] The forging machines currently in use often need to be combined with a clamping device for auxiliary forging. During the forging process, the fixing stability of the clamping device on the blank directly determines the forging accuracy of the blank. In the subsequent use process, the general clamping device often clamps the edge of the blank, and the part far away from the clamping drive device often shakes, which is not conducive to stable clamping. Secondly, the existing clamping device often takes a long time to calibrate for clamping blanks of different sizes, and the practicality of such clamping devices is poor. Summary of the invention
