Abstract
The utility model discloses a nozzle for a carbon dioxide welding gun. The nozzle comprises a first pipe and a second pipe, wherein the first pipe and the second pipe are connected through threads, the external connecting thread is arranged at one end of the first pipe, the internal connecting thread matched with the external connecting thread is arranged on the inner wall of the end portion of the second pipe, and the pipe wall on the tail portion of the second pipe is provided with a vent hole which is through from top to bottom. The nozzle further comprises a protective cover arranged on the inner wall of the second pipe, wherein the inner wall on the tail portion of the protective cover is provided with an internal thread used for being connected with the welding gun. The nozzle is formed by connecting the first pipe and the second pipe through the threads; in the welding process, nozzle deformation occurs and bonding is formed on the inner wall of the nozzle; when the nozzle needs replacing, only the first pipe needs to be dismantled and replaced by a new one, the whole nozzle does not need to be replaced, as a result, welding cost is reduced, and waste of resources is avoided.
Description
Technical field
The utility model relates to a kind of welder fitting, is specifically related to a kind of nozzle for carbon dioxide welding gun.
Background technology
Carbon dioxide welding gun take as a kind of the soldering appliance that carbon dioxide is protective gas, because the features such as its efficiency is high, cost is low and easy to operate are widely used in during welding produces.Carbon dioxide welding gun comprises the parts such as ignition tip, connecting rod, nozzle, insulator; yet; due to the high heat producing in welding process; very easily cause the distortion of nozzle; simultaneously; what in welding process, produce splashes; very easily in nozzle inner walls, form bonding, thereby affect the performance of gas shield, therefore; use after a period of time; usually need to change whole nozzle, yet conventionally there is the nozzle near nozzle in above-mentioned nozzle variant and bonded part; that is: the end of nozzle, has caused the waste of resource and the raising of welding cost thus.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, can effectively reduce the nozzle for carbon dioxide welding gun that consumptive material consumes.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of nozzle for carbon dioxide welding gun, comprise the first paragraph pipe and the second segment pipe that are threaded connection, one end of described first paragraph pipe is provided with outer connecting thread, the inner wall of end of described second segment pipe is provided with the interior connecting thread suitable with described outer connecting thread, and the afterbody tube wall of described second segment pipe is provided with the steam vent running through up and down; Described nozzle also comprises the protective sleeve of being located on second segment inside pipe wall, and the afterbody inwall of described protective sleeve is provided with the internal thread for being connected with welding gun.
Preferably: the length of described first paragraph pipe is less than the length of second segment pipe.
Preferably: described steam vent is uniformly distributed on the afterbody tube wall of second segment pipe.
Preferably: described protective sleeve is located on the inwall of second segment pipe by the mode of engagement connection.
Preferably: the mode that described protective sleeve is threaded connection is located on the inwall of second segment pipe.
Preferably: described first paragraph pipe is cylindrical.
Preferably: described first paragraph pipe is conical.
Preferably: described first paragraph pipe and second segment pipe are copper pipe.
Preferably: described protective sleeve is ceramic protective sleeve.
Compare with the nozzle of existing carbon dioxide welding gun, the beneficial effects of the utility model are, nozzle is formed by connecting by first paragraph pipe and second segment gas thread, in welding process, and the bonding forming in the nozzle variant of generation and nozzle inner walls, in the time of need to carrying out nozzle exchange, only first paragraph pipe need be pulled down, more renew pipe, and without by whole nozzle exchange, therefore save welding cost, avoided the wasting of resources.
Accompanying drawing explanation
Fig. 1 shows the sectional structure chart of nozzle described in the utility model,
Fig. 2 shows the structural representation of nozzle described in the utility model;
Fig. 3 shows the another kind of structural representation of nozzle described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
As shown in Figure 1-2, nozzle described in the utility model, comprise by metal heat-conducting material first paragraph pipe 1 and second segment pipe 2 that for example metallic copper is made, and the length of first paragraph pipe 1 is less than the length of second segment pipe 2, one end of described first paragraph pipe 1 is provided with outer connecting thread 11, the inner wall of end of described second segment pipe 2 is provided with the interior connecting thread suitable with the outer connecting thread 11 of first paragraph pipe 1, is also provided with the equally distributed steam vent running through up and down 21 on the afterbody tube wall of described second segment pipe 2.Described nozzle also comprises the protective sleeve 3 of being located on second segment pipe 2 inwalls; the length of described protective sleeve 3 is less than the length of second segment pipe 2; protective sleeve 3 is made as pottery by insulating materials; by engagement connection or the mode that is threaded, be located on the inwall of second segment pipe 2, and the afterbody inwall of protective sleeve 3 is provided with the internal thread 31 for being connected with welding gun.As one preferred embodiment, first paragraph pipe 1 described in the utility model not only can adopt cylindrical structural as shown in Figure 2, also can adopt conical structure as shown in Figure 3, the circular cone outlet 12 of its head is conducive to assemble and goes out to weld direction in welding process, and the outer wall of first paragraph pipe 1 middle part also can be provided with the external screw thread for increasing dismounting frictional force.
Adopt nozzle described in the utility model, use a period of time, the bonding forming in the nozzle variant of generation and nozzle inner walls, only first paragraph pipe 1 need be pulled down, more renew pipe, and without by whole nozzle exchange, therefore save welding cost, avoided the wasting of resources.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
