Middle plate bi-directional gas cutting chamfering equipment

Abstract

The invention relates to coal machine equipment, in particular to middle plate bi-directional gas cutting chamfering equipment. A traditional method for chamfering a middle plate comprises the steps that the middle plate is horizontally placed on the ground, a semi-automatic flame cutting machine is used for cutting one corner of the middle plate every time in a gas cutting mode, the flame cutting machine needs to be aligned four times when the gas cutting is conducted on the four corners, and the middle plate needs to be turned over one time. The machining efficiency is low, the labor intensity of workers is large, the machining quality is not stable, and huge potential safety hazards exist in the process of turning over the middle plate. The middle plate bi-directional gas cutting chamfering equipment is composed of a support, an adjusting cushion plate, a rotary frame locating disc, a guide rail, a rotary frame, the semi-automatic flame cutting machine, three sets of cutting torches and a loading locating device. According to the middle plate bi-directional gas cutting chamfering equipment, the adjusting cushion plate, the loading locating device and the three sets of cutting torches are adjusted only when a first workpiece is machined, and later when the middle plate is replaced and after the two edges of the middle plate rotate to the top positions respectively, the two symmetrical edges of the middle plate can be chamfered in a bi-directional gas cutting mode only by starting the flame cutting machine. According to the middle plate bi-directional gas cutting chamfering equipment, the two edges of the middle plate are chamfered in the bi-directional gas cutting mode easily and conveniently, and the machining efficiency is high.

Description

technical field [0001] The invention relates to a coal mining equipment, in particular to a special equipment for two-way gas cutting and chamfering of a middle plate. Background technique [0002] The middle trough for coal mines is welded by two trough sides and two middle plates, so the two symmetrical sides of the middle plate need to be chamfered (that is, welded bevel), and because the middle plate is thick, each side needs two-way gas cutting horn. The traditional processing method is to place the middle plate horizontally on the ground, and use a semi-automatic flame cutting machine to gas-cut and chamfer the middle plate. Only one corner can be gas-cut each time, and the four corners need to be aligned with the flame cutting machine 4 times. The plate is turned over once, so the processing efficiency is low, the labor intensity of the workers is high, and the processing quality is unstable. On the other hand, in the process of turning the middle plate, there is a g...
