Abstract
The utility model provides a composite structure conductive jet, which is used for gas metal arc welding. The utility model comprises a red copper body, wherein, the back end of the red copper body is provided with screw threads; the red copper body is provided with a feeding hole for welding wires; the front end of the body is assembled with a sheath jet which can be often replaced, and. the sheath jet is provided with a through hole. The sheath jet of the utility model is made by adopting powder alloy materials of which the electrical conductivity and the abrasion resistance are favorable; the service life is enhance by 7 times to 10 times; the process of welding is stable, which is important for automatic welding. The utility model has the advantages of convenient use, and the utility model is economical and reliable.
Description
The utility model relates to the composite construction ignition tip that a kind of gas metal-arc welding is used, and it comprises that the rear end of a red copper is threaded and have a welding wire to send the body in hole to, at the cover mouth that can often change of a band of the front end assembling through hole of body.
The ignition tip that existing gas metal-arc welding is used; integral body all uses red copper or chromium-bronze alloy material to make; because anti-wear performance is relatively poor; the little bore portion of ignition tip front end very easily weares and teares; (the red copper tip that Beijing innovation soldering set factory produces be exactly use at present a kind of widely) causes in the welding process and contacts the conductive site variation, the welding performance variation in the welding wire and ignition tip hole.Thereby also need often change ignition tip, the promptly time-consuming material that takes again.
The purpose of this utility model is to overcome weak point in the above-mentioned prior art and a kind of composite construction ignition tip is provided.Adopt that electric conductivity is good, the anti-wear performance powder alloy material superior far beyond red copper made Xiao Taozui, be set in red copper ignition tip front position again and make the composite construction ignition tip.Be 7～10 times of red copper ignition tip service life, because wear-resisting, welding wire contact conductive site remains at the front end of ignition tip, thereby welding process is stable.This is particularly important to automatic welding.
The drawing of accompanying drawing is described as follows:
Fig. 1: (1) body, (2) cover mouth
Fig. 2: (1) body, (2) cover mouth
Fig. 3: (1) body, (2) cover mouth
Shown in 1,2,3, the ignition tip body is to use red copper or chromium-bronze to make with reference to the accompanying drawings, and the cover mouth then is the tungsten copper powder alloy material, and sends hole perforation and coaxial to a through hole and with the welding wire of body.
The purpose of this utility model can reach by following measure, and is shown in Figure 1, at the front end of body a shrinkage pool arranged, and the cover mouth is embedded in this shrinkage pool of body, takes interference fit to make it unlikely under the high-temperature condition in welding process and deviates from.
The purpose of this utility model can also reach by following measure, and is shown in Figure 3, at the body front end one threaded cylindrical protrusions arranged, and cover mouth rear end has a shrinkage pool, and screw thread is arranged in the hole, makes it to be connected with body.
The purpose of this utility model can also reach by following measure, and is shown in Figure 2, at the body front end one shrinkage pool arranged, and screw thread is arranged in the hole, is connected with the threaded cylindrical protrusions in cover mouth rear end.
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:
Make the ignition tip body with red copper or chromium-bronze material, front end has a cylindrical shrinkage pool, to send the hole to coaxial with welding wire, re-use the anti-wear performance tungsten copper powder alloy material superior and make the cylindrical shroud mouth than materials such as red coppers, take the molybdenum filament cutting to make through hole in the central, the grip mouth is set in the body shrinkage pool then, interference fit, make cover mouth through hole and welding wire send hole perforation and coaxial with it to, constitute the composite construction ignition tip.
The utility model compared with prior art has following advantage:
Cover mouth anti-wear performance is much better than red copper, and replaceable, and the life-span can be improved 7～10 times, and main is the front end that welding wire contact conductive site remains at ignition tip, thereby welding process is stable. This is particularly important to automatic welding.
