Description

Technical Field

[0001] The utility model relates to the technical field of chamfering processing, and more specifically, to an automatic chamfering machine applied to a cold heading machine. Background Art

[0002] Automatic chamfering machine is a kind of equipment used on cold heading machine, which is mainly used to chamfer metal workpieces after cold heading. During the cold heading process, there are usually sharp angles or burrs on the edge of the workpiece, which needs to be chamfered to improve the surface quality and safety of the workpiece.

[0003] When the existing chamfering machine processes tubular workpieces of various sizes, it is often necessary to use a clamping device to clamp the workpiece. The existing clamping method is mostly to clamp and fix the outer wall of the workpiece. However, in this process, since both ends of the tubular workpiece often need to be chamfered and polished from the center position, the existing clamping devices mostly simply clamp the workpiece. However, the center position heights of both ends of workpieces of various sizes are different, which brings many inconveniences to the actual chamfering and polishing. It is very easy to affect the accuracy of the chamfering and polishing of workpieces of various sizes due to the deviation of the polishing angle;

[0004] Moreover, in the process of chamfering and grinding the workpiece, the waste chips generated by the grinding are very likely to splash everywhere due to the inertia of rotating grinding, which is extremely inconvenient to collect. The splashing of waste chips may cause the operator to be hit or scratched, causing injury. Especially for high-speed rotating grinding equipment, the speed and force of the waste chips flying are relatively large. Once hitting the human body, it may cause serious injury, posing certain safety hazards to the use.

[0005] In view of this, we propose an automatic chamfering machine applied to cold heading machines. Utility Model Content
