Problems solved by technology

Its defect is: 1, regulating valve is not stable enough to the adjustment of flux, thereby causes the work of this welding and cutting torch not stable enough; There is a large error, which affects the stability of the welding and cutting torch. Moreover, such a structure causes the processing and production of the welding and cutting torch to be relatively complicated, and the threaded part required for the screw connection of the nozzle and the through hole is extremely difficult during work. It is easy to be damaged by aging and the thread breaks, thereby reducing the service life of the welding and cutting torch; 3. The efficiency of the welding and cutting nozzle is low, which wastes a lot of energy

Embodiment Construction

[0016] Examples, see figure 1 with figure 2 As shown, the welding and cutting torch includes a main body 10 . The lower part of the main body 10 is provided with a through hole 11 passing through front and back, and an air pipe 21 and a gas pipe 22 communicate with the inside of the through hole 11 . The front opening of the through hole 11 is screwed with a suction pipe 30 , the rear opening is provided with an adjustment needle 50 , and the through hole 11 is provided with a nozzle 40 between the injection pipe 30 and the adjustment needle 50 . The rear portion of the suction pipe 30 is provided with a cylindrical insertion hole 31 . The front portion of the nozzle 40 protrudes into the insertion hole 31 . Simultaneously, the front side upper part of this main body 10 is provided with the regulating high-pressure pipe 60 that communicates with the side wall of this trachea 21, and the front end of this regulating high-pressure pipe 60 communicates with the front end of t...

Abstract

The invention discloses a welding and cutting torch. An adjusting column of the welding and cutting torch is separated into a threaded column and a first conical head which are mutually matched. A pressure spring is arranged on the lower portion of the first conical head, the threaded column always tends to move to the outside portion of a valve cavity, and matching error between an outer thread of the threaded column and an inner thread in a screw hole in a gland is eliminated. Further, the first conical head cannot rotate along with the threaded column, so that adjustment of an adjusting valve is quite accurate and stable. Meanwhile, a nozzle and a jetting and sucking pipe are in transition fit or interference fit, parts are easy to break during threaded matching, the distance between the nozzle and the jetting and sucking pipe are easy to adjust and kept stable, and operation stability of the welding and cutting torch is guaranteed. Furthermore, a welding nozzle is in threaded design and an opening is in a bundled design, so that gas has excellent speed and rotates when being jet and burned, and burning efficiency of the gas is improved.

Description

technical field [0001] The invention relates to the technical field of welding and cutting tools, in particular to a welding and cutting torch. Background technique [0002] A welding torch is a common metal welding and cutting tool. Usually, the welding and cutting torch includes a main body, the lower part of the main body is provided with a through hole through the front and back, the front side of the through hole is communicated with the gas pipe, and the rear side is communicated with the gas pipe, and the front opening of the through hole is screwed with a suction pipe. 1. An adjustment needle is provided at the rear opening, and a nozzle is arranged between the suction pipe and the adjustment needle in the through hole, a cylindrical jack is provided at the rear of the suction pipe, and the front part of the nozzle extends to the In the socket, at the same time, the upper front side of the main body is provided with an adjustable high-pressure pipe communicated with...
