Gas cutting guiding device

Abstract

Disclosed is a gas cutting guide device, comprising a clamping positioning mechanism and a variable-speed transmission mechanism (11). The clamping positioning mechanism comprises an end cap connection guide mechanism and a cutting torch mounting positioning mechanism. The end cap connection guide mechanism comprises a magnetic block (1) and a guide block (3). The magnetic block (1) is fixedly mounted on an end surface of an end cap (13) of a tube, and a threaded core shaft (102) is disposed at a central position of an end surface of the magnetic block (1). The guide block (3) is fitted on the threaded core shaft (102) and is rotatable about the threaded core shaft (102). The variable-speed transmission mechanism (11) is mounted on the threaded core shaft (102) of the magnetic block (1). The cutting torch mounting positioning mechanism is disposed on the guide block (3), and comprises a positioning block (7) disposed on the guide block (3) and slidable along the guide block (3) up and down and a clamping block (5) connected to the positioning block (7) and rotatable about the positioning block (7). The device is capable of guiding gas cutting of end caps of tubes with different diameters, limiting the axial movement of a cutting torch in the process of gas-cutting the end caps, and improving forming of gas-cut end surfaces of the tubes, thereby having high universality and efficiency.

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
