Background Art

[0002] The groove is a groove of a certain geometric shape that is processed and assembled at the part to be welded of the pipe fitting. Its main purpose is to weld the workpiece and ensure the welding quality.

[0003] Usually, the groove cut on the pipe fitting has a sharp edge, which can easily cut workers during welding. In addition, if the outer and inner sides of the welded part near the groove of the pipe fitting are not polished, the dirt on the outer and inner sides of the pipe fitting will dissolve into the welding position, resulting in reduced welding quality.

[0186] In this example, a blunt edge processing device 41 is provided to perform blunt edge grinding on the acute angle of the groove of the pipe 7 so that the acute angle forms a blunt edge.

[0187] By setting up the blunt edge moving device 42, the blunt edge processing device 41 has been moved, so as to achieve the technical effect of moving the blunt edge processing device 41 to the groove of the pipe fitting 7 to perform blunt edge processing on the groove; it is also used to achieve the technical effect of detaching the blunt edge processing device 41 from the groove of the pipe fitting 7 to end the blunt edge processing.

[0188] At the same time, the relative position of the blunt edge processing device 41 and the groove of the pipe fitting 7 can also be adjusted, thereby adjusting the position of the blunt edge processing device 41 for blunt edge processing on the groove, so as to avoid the situation where the blunt edge processing device 41 processes the groove at only one position, which causes the blunt edge processing device 41 to wear out quickly.

[0189] In this embodiment, the blunt edge processing device 41 includes: any one of an electric beveling machine, a chamfering machine, a special grinding device and a handheld grinding tool.

[0190] Electric beveling machine is a highly efficient beveling processing equipment, which uses the transmission of the motor to drive the tool to remove the workpiece, thereby realizing the flat, oblique, V-shaped and U-shaped beveling cutting of various materials.
