Embodiment

[0024] Example: A preferred embodiment of the present invention is that the mixing air pipe 4 and the cutting air pipe 13 are finally connected with the corresponding through holes on the back seat of the cutting nozzle 6, keeping the two passages unchanged. like figure 1 and figure 2 As shown, the inner cone cavity 1 and the outer cone cavity 12 are processed into a cavity piece with a length of 18 mm, a wall thickness of 3 mm, and an inner diameter of 17 mm using a copper rod with a diameter of 23 mm. The outer end of the cavity of the inner cone cavity 1 is set With blocking cover 2, figure 1The coaxial inner surfaces of the inner cone cavity 1 and the outer cone cavity 12 corresponding to the two pairs of cavities are designed with installation through holes with a diameter of 10.2mm, respectively on the inner sides of the two cavity installation through holes Or the outer edge is processed into a conical surface with a height of 3.4mm, which constitutes the inner con...

Abstract

The invention discloses a cutting torch gun with an adjustable cutting torch angle and an installing method of the cutting torch gun. The cutting torch gun comprises an inner conical surface cavity and an outer conical surface cavity; the periphery of the inner conical surface cavity and the periphery of the outer conical surface cavity are provided with through holes which are connected with a gas outlet pipe A and a gas outlet pipe B respectively, and the gas outlet pipe A and the gas outlet pipe B are both connected with corresponding through holes in a cutting torch backseat. A partition body is arranged in the middle of a pipe fitting, the two sides of the partition body are provided with blind holes which are communicated with the through holes formed in the pipe wall of the pipe fitting, the through hole located in the axle tube A end of the pipe fitting is connected with a mixed gas pipe, and the through hole located in the axle tube B end of the pipe fitting is connected with a cutting gas pipe. According to the cutting torch gun, an integrated connecting piece can perform rotation, fixation and sealing around axle tubes at an angle of 90-270 degrees. Furthermore, in some special spaces or limited spaces, it is unnecessary that a right-angled cutting torch and a straight cutting torch work alternately, and therefore work efficiency is improved.

Description

technical field [0001] The invention relates to a cutting torch, in particular to a cutting torch gun head with an adjustable cutting nozzle angle and an installation method thereof. Background technique [0002] As a main tool for gas cutting workpieces, cutting torches are widely used in metallurgy, petrochemical, machinery manufacturing and other industries. At present, according to the angle of the cutting nozzle at the front end of the cutting torch, it is divided into two types: 90-degree and straight cutting torches. In actual use, especially in some restricted construction spaces, these two angle torches are often used alternately. When exchanging cutting torches, the cutting oxygen and gas main valves must be closed before using tools to replace them. Usually, the cutting oxygen and gas main valves are far away from the work site, which brings inconvenience to the replacement of cutting torches and reduces work efficiency.
