Gas cutting guiding device

Abstract

The invention relates to a gas cutting guiding device which comprises a clamping locating mechanism and a speed-changeable transmission mechanism. The clamping locating mechanism comprises an end cover connection guiding mechanism and a gas cutting gun mounting locating mechanism, wherein the end cover connection guiding mechanism comprises a magnetic block and a guiding block, the magnetic block is fixedly arranged on the end surface of a pipe end cover, a threaded core shaft is arranged at the center of the end surface of the magnetic block, the guiding block is arranged on the threaded core shaft in a through manner and can rotate around the threaded core shaft. The speed-changeable transmission mechanism is arranged on the threaded core shaft of the magnetic block. The gas cutting gun mounting locating mechanism is arranged on the guiding block and comprises a locating block and a clamping device, wherein the locating block is arranged on the guiding block and can slide up and down along the guiding block, and the clamping block is connected with the locating block and can rotate around the locating block. The gas cutting guiding device disclosed by the invention can provide the gas cutting guiding for the pipe end covers with different diameters, and limits the axial drifting of a gas cutting gun and modifies the gas cutting end surface formation of pipes in an operation process of gas cutting the end cover; in addition, the universality is strong, the work efficiency is improved, and the large-scale investment and application of workshops is convenient.

Description

technical field [0001] The invention relates to a gas cutting processing tool for a metal pipe end cap, in particular to a gas cutting guide device for a metal pipe end cap. Background technique [0002] In the prior art, when the hydraulic pressure test of the boiler header is completed and the metal pipe hydraulic test end cover margin line is drawn, the gas cutting operator in the workshop uses a gas cutting gun to perform gas cutting operations on the header pump water end cover and the pipe joint. . If this method is used to remove the pump water end cover, a full circle of oxide layer with a certain thickness and extremely high hardness will be formed around the gas cutting opening at the end of the pipe. In addition, manual operation is adopted, and the end face of the gas-cut pipe becomes jagged, and the surface shape is very poor. [0003] The gas-cutting end cap of the above-mentioned pipe takes longer in the process of bevel re-boring, which will seriously affec...

Problems solved by technology

In addition, manual operation is adopted, the end face of the gas-cut pipe becomes jagged, and the surface shape is very poor

[0003] The gas-cutting end cap of the above-mentioned pipe takes longer in the process of groove re-boring, which will seriously affect the wear of the tool, especially the service life and machining accuracy of the equipment.

When processing such large-diameter pipe ports, the internal gears of the boring machine are constantly subjected to impact loads, which can easily cause gear breakage, increase the maintenance cost of the machine tool, and delay the manufacturing cycle of the product header

At the same time, the machining accuracy of the equipment will also be seriously affected
