Manual forging clamping device for machining

Technical Field

The invention belongs to the technical field of machining, and particularly relates to a manual forging clamping device for machining.

Background

Forging is a processing method which utilizes forging machinery to apply pressure on a metal blank to cause the metal blank to generate plastic deformation so as to obtain a forged piece with certain mechanical property, certain shape and certain size. The defects of as-cast porosity and the like generated in the smelting process of metal can be eliminated through forging, the microstructure is optimized, and meanwhile, because the complete metal streamline is preserved, the mechanical property of the forging is generally superior to that of a casting made of the same material. At present, some high-precision forgings are forged by clamping high-temperature blanks by a worker through a clamp, the worker continuously overturns or rotates the blanks through the clamp in the forging process, however, the clamp is too simple in structure, particularly the clamping end of the clamp is small in contact area with the blanks in the blank clamping process, and the situation of slippage or insufficient overturning angle is easy to occur.
