Description

TECHNICAL FIELD

[0001] The utility model relates to cutting equipment technical field, specifically is a kind of cutting equipment for tubular mechanical processing. BACKGROUND

[0002] Tubular part is the collective name of the parts in pipeline system, which plays the role of connection, control, direction change, flow distribution, sealing and support. Steel tubular parts are all pressure-bearing pipe fittings. According to different processing techniques, they are divided into four categories, namely, butt-welding pipe fittings, socket-welding and threaded pipe fittings, and flange pipe fittings. During the mechanical processing of tubular parts, cutting equipment is usually used for cutting.

[0003] The existing cutting equipment usually fixes the tubular part on the cutting table, and then fixes one end of the tubular part by the clamp. Since the bottom of the tubular part cannot be supported during fixing, the tubular part will be offset downward under stress during cutting, which will cause deviation of the cutting position of the tubular part, and thus the processing quality of the cutting equipment for the tubular part will be reduced.

[0004] According to the pipe cutting machine with the announcement number CN218799479U, the cutting assembly is arranged on the top of the base, and the cutting assembly includes a cutting disc. A vertical plate is fixedly arranged on the left side of the top of the base, and a rotating cylinder is rotatably arranged on one side of the outer wall of the vertical plate through a mounting groove. A clamping assembly is arranged on the rotating cylinder. A worm gear is arranged outside the rotating cylinder, and two mounting blocks are symmetrically arranged on the top of the base below the worm gear. A worm is connected to the opposite outer walls of the two mounting blocks through a bearing. The worm gear and the worm are meshed, and a motor is fixedly arranged on one side of the mounting block. The output shaft of the motor is fixedly connected to one end of the worm. The motor drives the worm to rotate, and the worm acts on the worm gear, so that the rotating cylinder rotates. In this way, the tubular part clamped in the rotating cylinder can rotate, and the large-diameter pipe diameter can be well cut.

Therefore, we need to propose a cutting equipment for tubular mechanical processing. INVENTION CONTENTS
