Technology method for improving angle cutting quality of equal angle steel

Abstract

The invention discloses a process method for improving the quality of corner cutting of equilateral angle steel, which comprises the following steps: step A: selecting a corner cutting machine; step B: fixing a fixed block on the workbench of the corner cutting machine; step C: drawing on the angle steel Upper chamfering line; step D: place the angle steel in the V-shaped through groove, and make the angle to be cut off on the angle steel be located at the place where the right angle is inverted on the through groove, and the chamfer line is located on the side where the right angle is away from the through groove; step E: Start the driving device, make the opposite sides of the limiting plates contact both ends of the angle steel, and fix the angle steel between the limiting plates; Step F: Start the angle cutting machine, and cut off the corners on the angle steel. In this way, through the above method, the angle steel for corner cutting can be fixed to prevent the side away from the cutting point from turning up when the angle steel is cutting the corner, which will reduce the quality of the angle steel incision, and even make the edge distance of the corner cutting not comply with the process regulations. Increase the repair times of angle steel and reduce the scrap rate of angle steel.

Description

technical field [0001] The invention relates to a corner cutting method, in particular to a process method for improving the corner cutting quality of equilateral angle steel. Background technique [0002] Steel towers are mainly used for power transmission and communication. Among them, the transmission line tower is referred to as the power tower, which is generally divided into five types according to its shape: wine glass type, cat head type, upper type, dry type and barrel type. , transposition tower (to replace the phase position tower of the wire), terminal tower and spanning tower, etc. Their structural characteristics are that all kinds of tower types are space truss structures, and the rods are mainly composed of single equilateral angle steel or combined angle steel, and the materials are generally Two kinds of Q235 (A3F) and Q345 (16Mn) are used. The connection between the rods is made of rough bolts, and the bolts are connected by shear force. The whole tower i...

Problems solved by technology

[0005] The purpose of the present invention is to provide a process method for improving the quality of angle steel cutting of equilateral angle steel, so as to solve the problem that when the tool is pressed down to cut angle steel angles, the angle steel that is not fixed will warp upwards at the side away from the cutting point when the angle steel is cut, reducing the angle steel. The quality of the cut, even the problem that the margin of the cut corner does not meet the process regulations
