Description

Technical Field

[0001] The utility model relates to the technical field related to forging processing, in particular to a large forging processing clamping device. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet. The difference in the complexity of the geometric structure of forgings determines that their die forging process and die design are significantly different. Clarifying the structural type of forgings is a necessary prerequisite for process design. In the processing of large forgings, clamping devices are required for clamping and fixing.

[0003] When working, the existing forging clamping device can often only clamp the two sides of the forging. The forging will still be offset during processing, and the clamping stability effect is not high, which affects the accuracy of forging processing. Therefore, this application provides a large forging processing clamping device to meet the needs. Utility Model Content
