Description

Welding gun spray pipe

Technical Field

The utility model relates to a welder technical field, especially a welder spray tube.

Background

The spray pipe is a common accessory of the welding gun, is arranged on a bent pipe of the welding gun and is mainly used for gathering shielding gas and protecting the accessory of the gun head. When the welding gun works, the temperature at the nozzle of the spray pipe is higher, so that the spray pipe is easily scrapped due to the damage of the nozzle of the spray pipe, and other parts of the spray pipe except the nozzle of the spray pipe are still intact at the moment, and a large amount of waste is painful; in addition, the welding site often needs to use the spray pipes with different nozzle diameters according to different working conditions, if the nozzle diameters need to be adjusted, the whole spray pipe needs to be replaced, and the convenience is poor.

The utility model discloses a chinese utility model patent CN 208019685U discloses a welder spray tube, it includes spray tube main part and barrel, it is provided with the hinge seat just to be located its top on the right-hand member face of spray tube main part, it has the barrel to articulate on the hinge seat, the left end portion of barrel seals, the guiding hole has been seted up on the left end portion of barrel, the limiting plate has set firmly on the left end portion of movable rod, the cover has the spring on the movable rod, the spring is located between barrel and the limiting plate, the one end of spring is fixed in on the limiting plate, the other end is fixed in on the barrel, the right-hand member portion of movable rod stretches into in the barrel, and set firmly the scraper blade on this tip.

Disclosure of Invention

The utility model discloses the technical problem that needs to solve provides a have welder spray tube of economic nature and convenience concurrently.

In order to solve the technical problem, the welding gun spray pipe of the utility model comprises a spray pipe head and a spray pipe body which are designed in a split type, wherein the spray pipe head is a replaceable spray pipe head; the nozzle head and the nozzle body are connected through the nozzle head through threads; the outer side of the connection part of the nozzle body and the nozzle head is provided with a spiral pressure groove, and the front end of the nozzle head is provided with a nozzle opening.

Preferably, the inner side of the spraying pipe body is provided with a spraying pipe body inner core, and the spraying pipe body inner core is fixed with a bakelite insulating part.

Preferably, the outer side of the connection part of the nozzle head and the nozzle body is provided with a surface knurling.

By adopting the structure, the utility model can effectively insulate the spray pipe from the electrified bent pipe, can level the inner cavity of the spray pipe, and can lead the connecting part between the spray pipe body and the inner part of the spray pipe head to be smooth, thus leading the protective gas flow to be smooth and avoiding the generation of welding seam bubbles caused by the unsmooth protective gas flow; the main function of the inner core of the spray pipe body is to connect the bent pipe, and different inner cores of the spray pipe body can be used to match the spray pipe body with different bent pipes.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic structural diagram of the welding gun nozzle of the present invention.

In the figure: 1 is the nozzle tip, 2 is the nozzle body, 1.1 is the nozzle orifice, 1.2 is the surface annular knurl, 1.3 is the nozzle tip screw thread, 2.1 is the heliciform indent, 2.2 is the bakelite insulating part, 2.3 is the nozzle body inner core.

Detailed Description

As shown in fig. 1, the welding gun spray tube of the present invention comprises a spray tube head 1 and a spray tube body 2 which are designed in a split type, wherein the spray tube head 1 is a replaceable spray tube head; the nozzle head 1 and the nozzle body 2 are connected through nozzle head threads 1.3; the outer side of the joint of the nozzle body 2 and the nozzle head 1 is provided with a spiral pressure groove 2.1, and the front end of the nozzle head 1 is provided with a nozzle orifice 1.1. But nozzle head 1 is the substitution, and the welding field has the requirement to the spray tube bore, only need according to specific circumstances change different bore nozzle head can, also can directly replace the nozzle head of damage, and nozzle body 2 can be used for a long time because operational environment low in temperature to the waste of use cost and resource has been reduced, nozzle head 1 can be through adopting chromium zirconium copper preparation or increase the method of nozzle mouth thickness increase the life of whole spray tube by a wide margin under the condition of increasing a small amount of costs.

The nozzle body front end has heliciform indent 2.1 to be used for connecting the nozzle head, uses the heliciform indent can be under the prerequisite that does not increase nozzle body copper pipe thickness (if nozzle body front end uses the screw thread, the copper pipe wall thickness of preparation nozzle body will be 1mm thick out) and form the structure of a similar screw thread and be used for connecting the nozzle head to manufacturing cost has been practiced thrift.

As shown in fig. 1, a nozzle body inner core 2.3 is arranged on the inner side of the nozzle body 2, and a bakelite insulating part 2.2 is fixed on the nozzle body inner core 2.3. The insulating layer of the spray pipe body is made of bakelite, so that the spray pipe can be effectively insulated from a charged bent pipe, the inner cavity of the spray pipe can be leveled, and the connecting part between the spray pipe body 2 and the spray pipe head 1 is smooth and level, so that the protective gas flow is smooth, and the generation of welding seam bubbles caused by unsmooth protective gas flow is avoided; the main function of the spray pipe body inner core 2.3 is to connect the bent pipe, and different spray pipe body inner cores 2.3 can be used to match the spray pipe body 2 with different bent pipes.

As shown in fig. 1, a surface knurling 1.2 is arranged on the outer side of the connection part of the nozzle head 1 and the nozzle body 2. The use of knurling on the nozzle tip surface increases the friction on the nozzle tip surface so that the operator can more easily thread the nozzle tip onto the nozzle body.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
