Efficient automatic cutting machine for rectangular t metal tubes

Abstract

An efficient automatic cutting machine for rectangular metal tubes comprises a workpiece conveying device assembly, a cutting device assembly and a finished product conveying device assembly. The workpiece conveying device assembly comprises a rack, a plurality of horizontal idler wheels, a feeding moving mechanism and a rectangular tube clamping mechanism. The rectangular clamping mechanism is fixed on the upper portion of the feeding moving frame. A transmission system and a rack are arranged on the lower portion of the feeding moving frame and form a conveying device capable of moving back and forth along a linear guide rail. The cutting device assembly comprises a rotary support which is arranged on the support, a rotation drive mechanism, a cutting head transverse moving mechanism fixed on the rotary support through a connecting block, a cutting head lifting mechanism arranged on a moving sliding table in the cutting head transverse moving mechanism, and a cutting gun arranged on the cutting head lifting mechanism, wherein the rectangular tubes can extend into or out of the rotary support. The rotation drive mechanism, the cutting head transverse moving mechanism fixed on the rotation drive mechanism and the cutting head lifting mechanism fixed on the transverse sliding table in the cutting head transverse moving mechanism form an annular cutting device which enables the cutting gun to rotate around the outline of a rectangular workpiece at 360 degrees.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a high-efficiency automatic cutting machine for metal square and rectangular tubes, which belongs to the field of special equipment for machining. Background technique [0002] Metal square tube is the abbreviation of metal square tube and rectangular tube, which belongs to the type of hollow steel. At present, in the industrial fields such as construction and vehicle manufacturing, metal square tubes are used more and more widely as components. However, there are no good methods and special equipment for the cutting and blanking of metal square tubes and the cutting and processing of various shapes of the ends in China at present, and some still use manual cutting methods. Therefore, the quality of the processed parts after cutting is very poor, and some of them refit the existing intersecting wire cutting machine for cutting round pipes, rotate the rectangular pipe like a round pipe, and t...

Problems solved by technology

Therefore, the quality of the processed parts after cutting is very poor, and some of them refit the existing intersecting wire cutting machine for cutting round pipes, rotate the rectangular pipe like a round pipe, and then use numerical control technology to control the cutting torch Cutting, although this method can cut out the required workpieces, but the clamping is very troublesome, the efficiency is low, and it cannot meet the requirements of mass workpiece cutting production
