Description

Technical Field

[0001] The invention relates to the technical field of flange processing, and in particular to an automatic flange processing device and a processing method thereof. Background Art

[0002] Flange is a part that connects pipes to each other and is used to connect pipe ends. That is, first fix two pipes on a flange plate respectively, add a flange gasket between the two flange plates, and fasten them together with bolts to complete the connection between the two pipes.

[0003] When drilling a large flange, the drill bit edge squeezes the material to generate shear stress. When the stress exceeds the yield strength of the material, the material at the edge of the hole is torn and curled to form burrs. Burrs not only affect product performance, but may also cause safety accidents and legal risks (seal failure, stress concentration, assembly interference, etc.). Therefore, it is very necessary to effectively deal with burrs. However, during the drilling process, debris will be generated, and some of the debris may remain in the hole or on the hole wall. If deburring is performed directly, these debris are easily crushed by the deburring milling cutter, forming scratches, which will affect the final quality of the flange. Summary of the invention
