Abstract

The utility model relates to a two-direction cutting torch. The utility model is characterized in that the joint of a cutting nozzle is additionally provided with a direct cutting nozzle; simultaneously branch pipes are respectively arranged on a cutting oxygen pipe and an air mixing pipe to be communicated with the direct cutting nozzle. When used, the two-direction cutting torch can randomly carry out gas cutting by the direct cutting nozzle to workpieces in a barrel body or workpieces lower than one meter and other workpieces which are not favorable for gas cutting by a lateral cutting nozzle. The utility model has the advantages of the existing cutting torch and adds gas cutting function with multiple directions and multiple angles, the space working state of the cutting torch is flexible, manpower and material resources can be saved, the work efficiency and slot quality are improved, and the utility model has important meanings to reduce welders' labour intensity and avoid scald and burn by metal slag.

Description

Two-direction cutting torch

The utility model is that a kind of oxygen and acetylene (or other imflammable gas) flame of mixed combustion of utilizing carries out the instrument of gas cutting, and particularly a kind of scope easy to use is wide, the reversible cutting torch of better function.

Existing cutting torch as gas cutting tool, its operation principle is the preheat flame that utilizes oxygen to mix with acetylene, the metal object of needs cutting is heated to the combustion melting degree, and then ejection pure oxygen in high pressure gas jet blows the dregs after the fusing off, thereby with the separated realization oxycetylene cutting of metal objects (being gas cutting).Oxycetylene cutting can be cut common and steel part special shape, and gas cutting has its purposes widely industrial.But it cuts that to chew all be to make side direction type structure (cut and chew and mixture pipe, the rectangular state of cutting oxygen pipe) existing cutting torch, can not be along with the variation of the position for the treatment of the gas cutting metal objects, direction and angle the space duty of conversion cutting torch, cause the welder to operate inconvenience, sometimes also can cause the damage of burning of scalding of regulus, reduce operating efficiency and slot quality the operative employee.

The purpose of this utility model be at and overcome above-mentioned defective, thereby a kind of easy to operate reversible cutting torch is provided, make it to adapt to multi-direction, the gas cutting of multi-angle needs.

The utility model is achieved in that its overall structure still includes to cut and chews joint, being distributed in this cuts the side direction of chewing on the joint and cuts and chew, cut with side direction and to chew cutting oxygen pipe and the mixture pipe that is connected, handwheel switch (has three, be used to control the circulation of oxygen, acetylene gas or mist), handle, be characterized in also having additional one on the joint and directly chewing cutting to chew to cutting, on cutting oxygen pipe and mixture pipe, also be respectively equipped with simultaneously separately the ventilation arm with directly chew be connected (perforation) to cutting.

Below in conjunction with accompanying drawing concrete structure of the present utility model and operation principle are described further.

Fig. 1 is the overall structure schematic diagram of the utility model cutting torch;

Fig. 2 can be used for sealing the structural representation that cuts the plug gas nut of chewing;

Fig. 3 only contains on the cutting torch directly to cutting the straight structural representation of chewing to the formula cutting torch.

Wherein: 1 side direction is cut and is chewed, and 2 cut and chew nut, and 3 cut and chew joint, 4 directly chew to cutting, and 5 cut and chew nut, 6 cutting oxygen pipes, the 6-1 arm of ventilating, 7 mixture pipes, the 7-1 arm of ventilating, 8 cutting oxygen handwheels, 9 oxygen handwheels, 10 handles, 11 acetylene handwheels, 12 oxygen tube junctions, 13 acetylene gas pipe joints, 14 plug gas nuts.

See figures.1.and.2, cut because of the side direction in the utility model and chew 1 and directly chew 4 and can not work simultaneously to cutting, during one of them work, another must sealed air-tight, so the utility model also must be equipped with and can be used for sealing two and cut the plug gas nut 14 of chewing usefulness.

With reference to Fig. 3, also can chew 4 simplified structure to cutting cutting to chew to make on the joint 3 only to contain directly, constitute another kind of embodiment of the present utility model with this.

Use the principle process of the utility model cutting torch as follows: owing to constitute directly chewing 4 and cut with side direction that to chew 1 structure the same of reversible cutting torch to cutting, all there are the ventilation arm 6-1 of cutting oxygen pipe 6 and the ventilation arm 7-1 of mixture pipe 7 to communicate, can utilize oxygen and acetylene that metal objects is cut equally with it.During use, when metal objects is dull and stereotyped or during the metal works that is horizontal, side direction on available this cutting torch is cut and is chewed 1 and carry out gas cutting, directly chewing and 4 just screw with plug gas nut 14 and sealed to cutting at this moment (screw off earlier to cut to screw on after chewing nut 5 again and fill in gas nut 14).When what treat gas cutting is the inner barrel workpiece, or is lower than the vertical workpiece below a meter, or the gas cutting height has the pipeline of obstruction in vain, is unfavorable for cutting when chewing 1 gas cutting with side direction, can use directly to cutting and chew 4 and carry out gas cutting, and side direction is cut and is chewed 1 and can be sealed with plug gas nut 14.

This novel cutting torch had both had the advantage of cutting torch, increased again gas cutting function multi-direction, multi-angle, the Space-Work state of cutting torch is versatile and flexible, for saving manpower, increase work efficiency and the slot quality, alleviate operative employee's labour intensity, and avoid during gas cutting scalding of regulus burn damage etc. all tool be of great significance.

Claims

1, a kind of reversible cutting torch that is used for gas cutting, comprise cutting and chew joint (3), be distributed in and cut the side direction of chewing on the joint (3) and cut and chew (1), cutting oxygen pipe (6) that is connected with the side direction cutting torch and mixture pipe (7), handwheel switch, handle (10), it is characterized in that also having additional one on the joint (3) and directly chewing (4) cutting to chew to cutting, on cutting oxygen pipe (6) and mixture pipe (7), also be respectively equipped with simultaneously separately the ventilation arm with directly chew (4) and be connected to cutting.

2, cutting torch according to claim 1 is characterized in that also being provided with and can be used for sealing two and cut the plug gas nut (14) of chewing usefulness.
