Multifunctional cylindrical cutting and beveling machine

Abstract

The invention relates to a cutting and beveling machine for beveling, cutting, milling and drilling a steel pipe and particularly relates to the cutting and beveling machine for beveling, cutting, milling and drilling a large-size circular or oval thick-wall steel pipe. The invention provides the following technical scheme that a multifunctional cylindrical cutting and beveling machine is characterized in that a cutting device comprises a propelling mechanism and a cutting and rotating mechanism, wherein the cutting and rotating mechanism comprises a base, a cutting drill bit knife holder, a transmission part and a motor; an output shaft of the motor drives the cutting drill bit knife holder to rotate through the transmission part; a screw rod of the propelling mechanism can push the base to slide; and a beveling knife mounting frame in a beveling mechanism can slide along the rotation of the screw rod in a progressing mechanism. With the adoption of the scheme, the invention provides the novel cutting and beveling machine for rapidly beveling, cutting, milling and drilling the large-size circular or oval thick-wall steel pipe to overcome the disadvantages in the prior art.

Description

technical field [0001] The invention relates to a cutting and beveling machine capable of beveling, cutting, milling and drilling steel pipes, in particular to a cutting and beveling machine for cutting, beveling, milling and drilling large round or elliptical thick-walled steel pipes. Background technique [0002] At present, the principle of equipment for cutting and beveling large round steel pipes is as follows. First, the cutting and beveling machine is fixed on the part to be cut, and then the steel pipe is rotated in a circle by the cutting blade. Stretch in a little, cut the steel pipe round by round, and finally cut off the steel pipe; secondly, remove the cutting device, install the tracking bevel device, and the tracking bevel device is also a gradual beveling round by round, this principle The cutting beveling machine has the following defects when cutting steel pipes: 1. The speed is slow, because the blade can only extend a little bit every time it cuts; 2. At ...

[0002] At present, the principle of equipment for cutting and beveling large round steel pipes is as follows. First, the cutting and beveling machine is fixed on the part to be cut, and then the steel pipe is rotated in a circle by the cutting blade. Stretch in a little, cut the steel pipe round by round, and finally cut off the steel pipe; secondly, remove the cutting device and install the tracking beveling device, which is also a gradual beveling round by round. The cutting beveling machine has the following defects when cutting steel pipes: 1. The speed is slow, because the blade can only extend a little bit every time it cuts; 2. At the last moment of cutting, the steel pipe is prone to tilt, and the tilt will break the blade Once the blade is broken, it is very troublesome to replace; 3. The blade needs to be replaced frequently; 4. The thick-walled steel pipe cannot be cut and grooved; 5. The groove surface is uneven
