Description

Technical Field

[0001] The invention relates to the technical field of chamfering machines, in particular to a pneumatic bidirectional chamfering machine. Background Art

[0002] Pneumatic bidirectional chamfering machine is a device that uses compressed air as a power source to drive. It is mainly used for chamfering the edges of metal pipes, flanges and other workpieces to remove burrs and sharp edges of the workpieces, so as to prepare for subsequent welding or assembly. The device is equipped with a control system to promote the chamfering process, and a power device to drive the blade for rotary cutting. It is also equipped with a clamping mechanism for fixing the workpiece and a feeding mechanism for loading the workpiece, etc., to finally complete the chamfering of both ends of the workpiece.

[0003] However, the existing pneumatic bidirectional chamfering machines lack an effective device for blocking and collecting material waste chips generated by cutting. During the chamfering process, the rotating cutting blade will cause a large amount of waste chips to be generated. These waste chips will splash in all directions due to inertia and scatter on mechanical equipment everywhere. They are difficult to clean up, affecting the operation of the equipment. In the process of splashing, they are easy to cause harm to the surrounding staff and affect the working environment. Finally, some of the waste chips will fall back and be adsorbed on the surface of the chamfered workpiece, causing cleaning troubles for the chamfered workpiece during subsequent processing and use. In any case, these waste chips will bring unnecessary troubles to production work and need to be effectively handled.

[0004] Therefore, in view of the fact that the above-mentioned existing pneumatic two-way chamfering machines lack an effective blocking and collecting device for material waste chips generated by cutting, during the chamfering process, the waste chips generated splash around and scatter everywhere in the equipment, which is difficult to clean up and affects the operation of the equipment. In addition, the splashed waste chips can easily cause harm to the staff and affect the working environment. The waste chips remaining adsorbed on the surface of the workpiece will also cause troublesome cleaning problems during subsequent processing and use. A pneumatic two-way chamfering machine can be designed to adapt the position of the cleaning brush two according to the pipe diameter of the workpiece to be processed. During the chamfering process of the workpiece, the material blocking tube is used to block the waste chips generated to prevent them from splashing out. At the same time, by controlling the rotation of the sealing ring, the sealing ring drives the N-shaped frame one and the N-shaped frame two to rotate synchronously. The cleaning brush one on the surface of the N-shaped frame one sweeps off the waste chips attached to the inner wall surface of the material blocking tube, and the cleaning brush two on the N-shaped frame two sweeps off the waste chips attached to the surface of the workpiece. The waste chips are swept into the drawer box in the material receiving box for unified cleaning and discharge. Summary of the invention

[0005] In order to overcome the lack of effective blocking and collecting devices for material waste generated by cutting in the existing pneumatic bidirectional chamfering machines, during the chamfering process, the waste generated splashes all around and scatters everywhere in the equipment, which is difficult to clean up and affects the operation of the equipment. The splashing waste can easily cause harm to the staff and affect the working environment. The waste remaining adsorbed on the surface of the workpiece will also cause troublesome cleaning problems during subsequent processing and use.

It solves the problem that the existing pneumatic two-way chamfering machine lacks an effective blocking and collecting device for material waste generated by cutting. During the chamfering process, the waste generated splashes all around and scatters everywhere in the equipment, which is difficult to clean and affects the operation of the equipment. The splashed waste can easily cause harm to the staff and affect the working environment. The waste remaining adsorbed on the surface of the workpiece will also cause cleaning troubles during subsequent processing and use.
