Abstract
The utility model discloses a welding gun spray pipe which comprises a housing, an inner core and an insulation layer arranged between the housing and the inner core, wherein spiral flutes are formed on the inner layer of the housing; knurling patterns are formed on the outer layer of the inner core; and the insulation layer is made of thermoset plastic. The utility model has the benefits that during the working of the welding gun, the housing, the inner layer and the insulation layer are prevented from being separated from one other after high temperature generated by the welding is transmitted to the spray pipe, so as to ensure the normal working of the welding gun and save the cost; and simultaneously the insulation layer has good insulating capacity and can prevent the housing from generating welding current, so that the welding operation can be performed normally, and the personnel safety of the operating staff is reliably assured.
Description
Technical field
The present invention relates to welding, specifically relate to a kind of welding gun jet pipe.
Background technology
The welding gun jet pipe is a critical piece of forming welding gun, common welding gun jet pipe comprises shell, inner core and be arranged on shell and inner core between the three-decker of insulating barrier, adopt the mode of mechanical presses that three-decker is linked together, insulating barrier of the prior art in addition adopts glass fiber as insulating barrier, when welding gun is worked, the high temperature that welding region produces can be delivered to welding gun jet pipe inside rapidly, because glass fiber temperature capacity and cementitiousness are very poor, phenomenon appears peeling off in shell that links together by mechanical presses and glass fiber when being subjected to heat-flash and inner core easily, very big to the welding job influence, therefore, if in case shell occurs, jet pipe can't use welding sequence to carry out when inner core separates with the glass fiber fibrage.
The utility model content
One of technical problem to be solved by this invention provides a kind of welding gun jet pipe, occurs segregation phenomenon to solve easily after each accessory is heated in the jet pipe in the prior art, thereby influences operate as normal.
For addressing the above problem, the present invention adopts following technical scheme to realize:
A kind of welding gun jet pipe, comprise shell, inner core and be arranged on shell and inner core between insulating barrier, the internal layer of described shell is provided with spiral goove, described inner core skin is provided with the annular knurl line, described insulating barrier is the thermosetting plastics insulating barrier.
Described thermosetting plastics insulating barrier is unsaturated phenolic resins insulating barrier.
Described shell is the red copper shell.
Described inner core is the brass inner core.
In the such scheme, the internal layer of shell is and the bonding position of thermosetting plastics insulating barrier, adopt the structure of screw thread ditch, make the mutual frictional force of internal layer and insulating barrier increase, the skin of inner core is and the bonding position of thermosetting plastics insulating barrier simultaneously, adopts annular knurl line structure also to increase the cohesive force of inner core and insulating barrier, and insulating barrier adopts the thermosetting plastics insulating barrier, preferred unsaturated phenolic resins insulating barrier makes insulating barrier have good insulating properties, hear resistance and caking property.
The beneficial effects of the utility model are: when welding gun in when work, after the high temperature that welding region produces is delivered to jet pipe, can not produce the phenomenon of shell, internal layer, insulating barrier separation, guaranteed normally carrying out of work, provide cost savings, simultaneously insulating barrier has good insulating capacity, prevents that shell from producing welding current and making welding normally to carry out and provide reliable assurance to operating personnel's personal safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is the red copper shell, and 2 is the red copper inner core, and 3 is unsaturated phenolic resins insulating barrier
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of welding gun jet pipe, comprise red copper shell 1, brass inner core 2 and be arranged on shell and inner core between unsaturated phenolic resins insulating barrier 3, the internal layer of described shell is provided with spiral goove, described inner core skin is provided with the annular knurl line.
Concrete operation is as follows: red copper shell 1 and brass inner core 2 are fixed in the mould, unsaturated phenolic resins is utilized injector, the phenolic resins of molten condition is injected in the mould, since the internal layer of red copper shell 1 in advance car gone out spiral goove, liquid phenolic resins can be docile the internal layer that is bonded in red copper shell 1, after the phenolic resins cooling, also formed and the corresponding helical structure of spiral goove, in like manner, the annular knurl line of brass inner core 2 is bonding with liquid phenolic resins, make and on cooled phenolic resins insulating barrier 3, also formed and brass inner core 2 corresponding annular knurl lines, therefore the internal layer of the skin of phenolic resins insulating barrier 3 and red copper shell 1 is strengthened fixing by the screw thread ditch, the skin of the internal layer of phenolic resins insulating barrier 3 and brass inner core 2 is strengthened fixing by the annular knurl line, lines each other agrees with mutually, has increased frictional force.
