Groove cutting method and robot

Abstract

The invention belongs to the technical field of flame cutting, and particularly relates to a groove cutting method and a robot. The method comprises the following steps that 1, a plate is transferred to a positioning tool through auxiliary equipment; 2, the area, close to the edge, of the bottom of the plate is polished and cleaned; 3, metal wires are welded in the area, close to the edge, of the polished and cleaned bottom; 4, a refractory material curing layer is sprayed in the area, close to the edge, of the bottom where the metal wires are welded; 5, the end of the plate is subjected to flame cutting, and a groove curved surface is formed; meanwhile, the flowing-down metal liquid forms a cutting bump on the refractory material curing layer; 6, the cutting knots and the refractory material curing layer are removed; and 7, the metal wires are removed. According to the method, the groove cutting nodule removal efficiency is improved, the cutting nodule removal time is shortened, the manpower and material resource cost is saved, the medium-thickness plate groove logistics chain bottleneck is eliminated, the medium-thickness plate groove delivery speed is increased, and the medium-thickness plate groove continuous production capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of flame cutting, in particular to a groove cutting method and a robot. Background technique [0002] Flame cutting will produce cutting nodules on medium-thick plates and bevels, especially the lower cutting nodules are very large, often reaching 8~10mm in height. Since this will seriously affect the normal production of the subsequent robot automated production line, it is necessary to try to eliminate or reduce the cutting. tumor. The cutting tumor not only affects the product quality but also endangers the equipment. Generally, the method of manually cutting the nodules is adopted. After the groove of the medium-thick plate is off-line, it is manually removed with a chisel. Some cutting nodules are closely connected with the base material and need to be cut off with a cutting gun. The temperature of the bevel of the medium and thick plate is as high as 550 degrees after the off-line, and the tumor remo...

AI Technical Summary

Problems solved by technology

The temperature of the bevel of the medium and thick plate is as high as 550 degrees after the off-line, and the tumor removal personnel who work in the off-line area for a long time are prone to burns, heatstroke and other personal injury accidents

Secondly, the operators work in a high temperature environment, which greatly reduces the working efficiency

Thirdly, after the bevel of the medium-thick plate is cooled by the slow cooling pit, the cutting nodules attached to the cutting surface of the bevel of the medium-thick plate harden, and the bonding force with the base material of the bevel of the medium-thick plate becomes stronger, and it is more difficult to manually clean the cutting nodules. difficulty

When the slow cooling time reaches the bevel of the medium-thick plate, it needs to be shipped out of the pit in time. Due to the low efficiency of manual cutting of the bevel, the bevel of the medium-thick plate cannot be shipped in time, and the bevel removal has become a bottleneck restricting production.

On the other hand, if you encounter a plate groove that needs red delivery, it will take a long time to manually remove the tumor, which will increase the temperature drop time of the plate groove in the normal temperature environment and affect the structure of the plate groove Formation, resulting in a decline in the quality of the plate groove
