Description
Technical Field
[0001] The utility model relates to the technical field of metal clamps, in particular to a combined clamp for heat treatment of metal parts. Background Art
[0002] Metal heat treatment is a process in which a metal or alloy workpiece is heated to a suitable temperature in a certain medium, kept at this temperature for a certain period of time, and then cooled at different speeds in different media to control its performance by changing the surface or internal microstructure of the metal material. Among them, the corresponding angle needs to be used during heat treatment of metal parts.
[0003] At present, existing clamps usually use a double-sided fixing method to clamp metal parts. However, due to the deformation interference during the heat treatment process, the metal parts are subjected to uneven force in the positions not in contact with the clamps, which may cause deformation and affect the overall structure of the metal parts.
