Cutting device for fitted angle and unlimited rotation bevel

Abstract

A cutting device for a fitted angle and un unlimited rotation bevel comprises an electric system and an X-Y-Z mechanical system. The present invention is characterized in that the cutting device also comprises a fitted angle bevel head and a peripheral anti-collision protective bracket of a cutting gun; the electric system comprises a numerical control system, an electric appliance cabinet and a plasma power supply; the X-Y-Z mechanical system is a gantry three-dimensional motion system comprising a workbench, an X shaft, a Y shaft and a Z shaft, and the X shaft, the Y shaft and the Z shaft are all straight line shafts; the fitted angle bevel head is fixedly arranged on the X-Y-Z mechanical system, and the bevel processing is carried out for a steel plate by controlling the cutting gun to make motion along five shafts with the numerical control system; the fitted angle bevel head consists of an A shaft, a fixing frame, a B shaft, a cantilever, a cutting gun, a corner joint plate, a rocker arm and a three-dimensional anti-collision and automatic resetting device of the cutting gun. The fitted angle bevel head adopts a space fitting production mode for bevel angles, having the advantages of high motion speed, good seal properties and simple structure.

Description

technical field [0001] The invention belongs to the field of plasma steel plate cutting equipment, and in particular relates to a bevel cutting device with fitting angle infinite rotation. . Background technique [0002] The fitting angle infinite rotary bevel cutting device is a difficult comprehensive technology in the international welding and cutting industry, which requires sophisticated robot technology, numerical control technology, plasma technology research and manufacturing technology. Widely used in aerospace, shipbuilding, metallurgy, machining industries. The main function is to cut various curved grooves on the steel plate that needs to be welded, without the need for secondary processing. Cut sheets can be used directly for welding. [0003] At present, this type of equipment has the following defects: the cutting accuracy of the bevel is not high; the torch is easily damaged due to misuse; because the cutting machine produces a large amount of oxidized met...

Problems solved by technology

[0003] At present, this type of equipment has the following defects: the cutting accuracy of the bevel is not high; the torch is easily damaged due to misuse; because the cutting machine produces a large amount of oxidized metal dust during cutting, the metal dust is high in temperature and floats in the air with the cutting geothermal airflow , will enter the parts and bearings of the bevel head to cause wear and damage of the parts
