Description
Technical field
The utility model relates to a kind of pipeline automatic gas cutting machine with hunting cutting function.
Background technology
Traditional pipe cutter can not carry out the angle cutting, for head it off, I have invented notification number is CN03211351X " pipeline automatic gas cutting machine ", and it is to be made of cutting torch assembly, electric walking car, rigid track, triangle link gear, the lower margin that is located on the rigid track.The pipe cutter of this structure is because the cutting torch assembly adopts elasticity to be connected with the walking car, and there is certain deviation in the line of cut of otch and demarcation, and the mouth of pipe end face injustice that is cut, and weld gap is inhomogeneous when causing welding, influences welding quality.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of 0-3 of cutting ° angle, and the line of cut of otch and demarcation coincide the pipeline automatic gas cutting machine with hunting cutting function that the mouth of pipe end face that is cut is smooth.
The pipeline automatic gas cutting machine with hunting cutting function that the utility model relates to comprises Circular Rigid track and cutting torch assembly, the electric walking dolly is installed on rigid track, a plurality of lower margins are installed below rigid track, its special character is: be hinged with unsteady arm in electric walking dolly side, between unsteady arm is away from electric walking dolly one end and electric walking dolly, air spring is installed, away from electric walking dolly one end the high wheel of cutting torch control is installed downwards at unsteady arm, described cutting torch assembly is installed on the arm that floats, and this pipeline automatic gas cutting machine with hunting cutting function also is provided with the elasticity scriber that can be installed on the cutting torch assembly.
Above-mentioned pipeline automatic gas cutting machine with hunting cutting function, the stepped scriber that described elasticity scriber is by sleeve, be installed in gland that sleeve rear end mouth and middle part be provided with fairlead, be installed in the sleeve and have a back-moving spring constitutes, and the two ends of described scriber are drawn by the fairlead on barrel forward end mouth and the gland respectively.
The utility model has the advantages that: by the arm that floats, cooperation between the high wheel of air spring and cutting torch control, make the high wheel of cutting torch control be close on the outer wall of steel pipe all the time, before the cutting elasticity scriber is clamped on the cutting torch clamper, utilize the elasticity line to depict the scarfing line tracking, thereby exactly rigid track is locked on the steel pipe, guarantee that cutting wind line cuts according to the line of cut of demarcating all the time, the line of cut of scarfing and demarcation is coincide, can realize the hunting cutting, the steel pipe mouth of pipe end face that is cut is smooth smooth, weld gap was even when the steel pipe after the cutting docked, thereby guaranteed welding quality.
