Anti-deformation metal pipe cutting device

Abstract

The invention discloses an anti-deformation metal pipe cutting device which comprises a base. A cutting table is fixedly connected onto the base; a second motor is fixedly connected to the side, away from the cutting table, of the base; a gearbox is fixedly connected to the position, close to the second motor, of the cutting table; an output shaft of the second motor is connected with the gearbox; a main shaft is rotationally connected onto the outer wall of the upper end of the gearbox; a clamping and fixing device is arranged on the main shaft; and a cutting groove with a semi-arc-shaped section is formed in the cutting table. According to the equipment, the clamping and fixing strength of a metal pipe is improved, so that the cutting stability is improved; the inner walls, located on the two sides of a cutting opening, of the metal pipe can be supported during cutting, so that the cutting opening is prevented from deforming; the rotating speed of the metal pipe is controlled to be balanced, so that cutting is more neat, and damage to a cutting blade is greatly reduced; and water spraying cooling treatment is added to improve the cutting quality and prolong the service life of the blade.

Description

technical field [0001] The invention relates to the technical field of metal pipe cutting, in particular to a deformation-resistant metal pipe cutting device. Background technique [0002] After retrieval, the authorized publication number CN107150144B proposes a metal pipe cutting device, which includes a base, a conveying mechanism and a cutting mechanism are arranged on the base, and a shock-absorbing buffer mechanism is arranged on the lower surface of the base. The beneficial effects of the invention are: The service life of the equipment is increased, and the practicability is strong. [0003] However, the above invention still has the following shortcomings. Because the metal tube has a hollow structure, and the circular cross-section support is poor, the metal tube is easily deformed at the cutting opening when it is cut and pressurized. At the same time, there is less cooling and cooling mechanism at the cutting point. Due to the high high-speed friction temperatur...

Problems solved by technology

[0003] However, the above-mentioned invention also has the following deficiencies. Because the metal tube is hollow, and the circular cross-section has poor stability, the metal tube is easily deformed when the metal tube is cut under pressure. At the same time, there is less cooling mechanism at the cutting place. Due to the high temperature of high-speed friction, the metal at the cutting edge is prone to oxidation and phase transformation, which affects the quality of the cutting edge. Therefore, a metal pipe cutting machine with anti-deformation is proposed. device
