Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe trimming, in particular to an automatic trimming mechanism for welding pipes. Background Art
[0002] Trimming welded pipe fittings involves trimming burrs and excess material to achieve the desired width or size. This process typically involves precise trimming of the pipe to ensure that its appearance and quality meet standards. Trimming improves the aesthetics and performance of welded pipe fittings, while also contributing to the overall quality and service life of the fittings.
[0003] Patent number CN220240160U discloses an automatic trimming machine for welding pipe fittings, comprising a base and a fixed base, a stand provided on the left side of the base, a linear slide installed on the stand, a cutting machine installed outside the linear slide, a cutting knife provided on the right side of the cutting machine, a handle fixedly connected to the left side of the stand, a fixed base provided on the right side of the base, a drive motor installed in the fixed base, and an output shaft of the drive motor fixedly connected to a rotating base. The automatic trimming machine for welding pipe fittings is provided with a rotating base, a limit block, a drive motor, and a limit cylinder. The bottom of the pipe fitting is seated on the positioning angle block. The limit cylinder pushes out the limit block, pressing and supporting the stainless steel pipe fitting from the inside. The positioning angle block moves downward and leaves the stainless steel pipe fitting. The drive motor drives the stainless steel pipe fitting to rotate. This trimming machine solves the problems of poor cutting accuracy and many burrs by fixing and limiting the stainless steel pipe fitting and stably rotating it.

The pipe will vibrate during cutting. When the pipe is longer, since it is only fixed at the bottom, the end of the pipe away from the limit block will shake more violently during rotation, and there is a risk of the pipe detaching, which poses a great safety hazard during cutting.
