Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a clamping device for straightening machines. Background Art

[0002] The straightening machine is an automatic detection and straightening device designed for shaft products that undergo bending deformation after heat treatment.

[0003] After the straightening machine has straightened the shaft and rod workpiece, one end of the shaft and rod workpiece automatically moves until it is completely out of the straightening machine. It is usually unloaded manually or the unloading machine automatically receives the material. Manual unloading has certain safety hazards and is time-consuming, labor-intensive and impractical. The unloading machine automatically receives the material, and most unloading machines do not have a clamping function. Shaft and rod workpieces are unloaded automatically, resulting in one end of the shaft and rod workpiece being in a free state during the straightening process, which has certain safety hazards and poor use effect. For this reason, we provide a clamping device for a straightening machine to solve this problem. Utility Model Content
