Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamping devices, in particular to a clamping device for heat treatment of metal materials. Background Technique
[0002] At present, large metal materials need to use clamping devices to clamp them out of the heat treatment equipment after heat treatment. At present, there are still some problems in the use of traditional clamping devices. For example, the traditional clamping device for clamping large metal materials is generally a mechanical claw, which can generally only be used to clamp metal materials of the same shape, such as square materials. When clamping cylindrical materials, the contact area with the cylindrical materials is limited, and it is very easy to have an unstable clamping situation during clamping. At the same time, the traditional clamping device generally has only one clamping claw. When in use, the gap time between clamping and loading and clamping and unloading is relatively long, resulting in a relatively long time required for large-scale heat treatment of metal materials.
