A fixed fixture for simultaneous cutting of multiple rectangular steel pipes

Abstract

The invention relates to a fixing fixture for synchronous cutting of multiple rectangular steel pipes. The fixing fixture comprises a worktable, portal frames, pressing devices, supporting devices anda clamping device; the portal frames are symmetrically arranged on the left and right sides of the worktable through a sliding mode; the pressing devices are arranged on the portal frames through a sliding mode; a rectangular through groove is formed in the middle part of the worktable; the supporting devices are arranged in the rectangular through groove in sequence from left to right; and the clamping device is arranged on the left side of the upper end surface of the worktable, and is positioned on the left side of the portal frame on the left side of the worktable. The fixing fixture cansolve such difficulties as easy deformation of cutting places of the rectangular steel pipes or even bending deformation of the whole rectangular steel pipes due to cantilever beam type cutting formedby fixation of one ends of the rectangular steel pipes by using a fixture without needing other fixing tools, easy blockage of cutters and different cutting sections in a traditional fixing fixture for rectangular steel pipe cutting.

Description

technical field [0001] The invention relates to the field of steel pipe cutting jigs, in particular to a fixed jig for synchronously cutting multiple rectangular steel pipes. Background technique [0002] Fixture refers to the device used to fix or install the processing object in the process of mechanical manufacturing so that it can occupy the correct position to accept construction or inspection. It is also called fixture. The fixture has great versatility, high degree of standardization and quick operation. Safety and other features, the special fixture has the characteristics of specific service objects and strong pertinence. Nowadays, when cutting rectangular steel pipes, the fixture is usually used to fix the rectangular steel pipe first, and then the single rectangular steel pipe is processed, but during the cutting process. The following problem occurs: [0003] 1. Usually, only one end of the rectangular steel pipe is fixed with a clamp, without other fixing tools...

AI Technical Summary

Problems solved by technology

[0007] The present invention can solve the problem of the existing fixing jig for cutting rectangular steel pipes. Usually, only one end of the rectangular steel pipe is fixed with a jig without other fixing tools, forming a cantilever beam cutting, which is easy to cause deformation of the cutting part of the rectangular steel pipe, and even the entire rectangular steel pipe. The phenomenon of deformation and bending. At the same time, during the cutting process of the middle part of the rectangular steel pipe, the two ends of the rectangular steel pipe will be tilted upwards, and the center will be shifted toward the cutting position. The cutting knife is prone to jamming, and the cutting section is uneven. It is easy to bend and deform. Cutting a rectangular steel pipe at a time has low work efficiency and low benefits, and it is easy to increase the labor intensity of workers. Usually, rigid clamps are used to clamp and fix it, which may easily cause cracks on the clamped parts of the rectangular steel pipe. Deformation and other problems
