Cutting equipment with protection function

Abstract

The invention belongs to the technical field of cutting devices, in particular to cutting equipment with a protection function. The cutting equipment with the protection function comprises a mounting frame, a threaded rod, auxiliary wheels, a mounting rod, a cutting wheel and a protection mechanism, wherein, the cross section of the mounting frame is concave, and the auxiliary wheels are rotationally connected into the upper wall of the inner side of the mounting frame; the number of the auxiliary wheels is two, the auxiliary wheels are connected through a transmission belt, and the mounting rod is arranged below the auxiliary wheels; the right end of the mounting rod is rotationally connected to the outer wall of the mounting frame, the cutting wheel is rotationally connected into the left end of the mounting rod, and the threaded rod is arranged at the lower end of the mounting rod in a contact mode; and a metal pipe and the cutting wheel actually do differential motion, the rotating speed of the cutting wheel is far higher than that of the metal pipe, when the metal pipe is cut through the cutting wheel, the metal pipe can rotate automatically, the cutting wheel makes uniform contact with the outer surface of the metal pipe, and therefore, a notch of the metal pipe is prevented from sinking due to cutting from a certain fixed position.

Description

technical field [0001] The invention belongs to the technical field of cutting devices, in particular to a cutting device with protection function. Background technique [0002] With the development of the modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and highly intelligent automatic cutting functions are also increasing. The development of CNC cutting machines must adapt to the requirements of the development of modern machining industry. Cutting machine is divided into flame cutting machine, plasma cutting machine, laser cutting machine, water cutting and so on. The laser cutting machine has the fastest efficiency, the highest cutting precision, and the cutting thickness is generally small. The cutting speed of the plasma cutting machine is also very fast, and the cutting surface has a certain slope. The flame cutting...

Problems solved by technology

[0003] In modern society, it is often necessary to cut metal pipes to facilitate installation, and the cutting of metal pipes is usually done by a cutting machine, and the most commonly used is a cutting machine with a saw gear, but this cutting During the cutting process, the machine will generate a large pressure on the cutting side of the metal tube, which will easily make the metal tube after the cutting is concave and elliptical, which will reduce its accuracy.
