Clamp for cold-drawn bar machining

The invention relates to the technical field of profile clamping, in particular to a cold-drawn bar machining clamp which comprises a placing plate, a driving device, a clamping device, an adjusting device and a blocking device. The clamping device can clamp and limit a plurality of cold-drawn bars at the same time, the cold-drawn bars can be machined at the same time conveniently, a triangular structure is formed among the clamped cold-drawn bars, the stability of supporting the cold-drawn bars is improved, and the driving device, the clamping device, the adjusting device and the blocking device are matched with one another, so that the working efficiency is improved. The conveying length of the cold-drawn bar can be changed within a certain range, the use flexibility of the clamp is improved, the cold-drawn bar can be intermittently and automatically conveyed, an operator does not need to repeatedly clamp and disassemble the cold-drawn bar, the consumption of labor force is reduced, and the clamping and con
