Full-automatic angle-adjustable tube cutting machine

Abstract

The invention belongs to the technical field of tube processing, and relates to an automatic tube cutting machine by which an included angle is formed between two end faces of a metal tube. The cutting machine comprises a base, a clamping sleeve, a cutting device, a feeding mechanism, a rotating mechanism and an angular disc, wherein the cutting device comprises a motor and cutting saw blades connected with the motor; the angular disc is arranged on the base by a bearing, and the motor is fixed on the angular disc; the feeding mechanism comprises a rotating-mechanism support seat; and the rotating mechanism comprises a rotating sleeve, a gear, a rotating cylinder and a driving rack, wherein the rotating cylinder is fixed on the rotating-mechanism support seat, a piston of the rotating cylinder is connected with the driving rack, and the gear is fixed on the outer cylinder wall of the rotating sleeve. In the invention, a tube is clamped by using the clamping sleeve and the rotating sleeve, the included angles between the cutting saw blades and a tube are adjusted by using the angle-adjustable angular disc, and the rotating sleeve (the outside of the rotating sleeve is provided witha gear) is driven to rotate by using the rotating cylinder and the driving rack, thereby achieving the purpose that a tube rotates by an angle.

Description

technical field [0001] The invention belongs to the technical field of pipe material processing, and relates to a pipe material cutting machine, in particular to an automatic pipe material cutting machine for making two ends of a metal pipe material form an included angle with each other. Background technique [0002] As we all know, in the production of metal pipe fittings, pipe blanking and cutting is an indispensable process. At present, there are various automatic and semi-automatic pipe cutting machines on the market. However, in the production of elbow joints, in order to save materials and obtain products with relatively uniform wall thickness, it is necessary to cut a pipe whose two ends form an angle with each other as a semi-finished product. At present, there is still no automatic equipment for cutting this pipe at home and abroad. , the common practice in the industry is to use a manual or semi-automatic cutting machine to adjust the clamp and the cutting blade f...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a convenient, efficient and stable fully automatic angle-adjustable pipe cutting machine. When the cutting machine is used, only the operator needs to replace the raw material of the pipe, and the cutting machine itself can continuously and automatically cut the semi-finished pipes whose two ends form an included angle. , the angle and length of the product obtained are very stable. Since the equipment is automatically cycled most of the time, the production mode of one person and multiple machines can be realized, which solves the shortcomings of manpower consumption, waste of raw materials, and unstable product quality in the prior art.
