Abstract
The utility model relates to a carbon dioxide welding is with electrically conductive mouth, including copper body, copper body is including thick cylindrical body (1) and the thin cylindrical body (2) that link to each other, be provided with the external screw thread on thick cylindrical body (1), the well core housing of thick cylindrical body (1) is equipped with a hollow cylinder shape nonrust steel bushing (5), the center of hollow cylinder shape nonrust steel bushing (5) and thin cylindrical body (2) is provided with cylindrical through -hole (3), the end of the hollow cylinder nonrust steel bushing of shape (5) is provided with horn mouth (4) that link to each other with cylindrical through -hole (3). This carbon dioxide welding is with electrically conductive mouth electric conductivity is good, the price is low, and more wear -resisting, be difficult for burning out long service life.
Description
Technical field
The utility model belongs to technical field of welding equipment, relates to a kind of ignition tip, is specifically related to the ignition tip that a kind of carbon dioxide welding is used.
Background technology
Carbon dioxide welding will use ignition tip, has through hole in described ignition tip, so that welding wire passes.But existing contact tip for carbon dioxide welding is all only have copper to become usually, and its through hole is generally cylindrical hole.Copper is not wear-resisting, and therefore, in use, through hole may be worn.And because the fusing point of copper is relatively low, in welding process, along with the carrying out of welding, temperature will raise gradually and may occur electric arc, thus make the through hole in ignition tip become large gradually, occur the situation that ignition tip burns out.Therefore, the ignition tip that this fine copper is made is not wear-resisting, easy burn-out, and service life is low.Meanwhile, the length of the ignition tip that this fine copper is made is larger, thus causes the waste of copper, and price comparison is high.
In view of the above-mentioned technological deficiency of prior art, in the urgent need to developing a kind of novel contact tip for carbon dioxide welding.
Summary of the invention
It is low that the purpose of this utility model is to solve not wear-resisting, easy burn-out that contact tip for carbon dioxide welding exists, service life, and the problem such as expensive.
To achieve these goals, the utility model provides following technical scheme: a kind of contact tip for carbon dioxide welding, it comprises copper body, described copper body comprises connected thick cylindrical body and thin cylindrical body, described thick cylindrical body is provided with external screw thread, it is characterized in that, the center of described thick cylindrical body is provided with a hollow cylinder stainless steel sleeve, the center of described hollow cylinder stainless steel sleeve and described thin cylindrical body is provided with cylindrical hole, the end of described hollow cylinder stainless steel sleeve is provided with the horn mouth be connected with described cylindrical hole.
Further, wherein, the length of described copper body is 4.2cm, and the diameter of described thick cylindrical body is 4mm, and the diameter of described bell-mouthed large end is 1.2mm, and the diameter of small end is 0.8mm.
Further, wherein, the thickness of described hollow cylinder stainless steel sleeve is 0.2mm.
Contact tip for carbon dioxide welding of the present utility model is provided with stainless steel sleeve, makes it more wear-resisting, and in addition, horn mouth also makes welding wire in use more be not easy to contact with the wall of through hole, further increases its wearability; Meanwhile, ignition tip endoporus is greatly constant, and welding wire contacts well with ignition tip, makes its not easy burn-out, reduces welding machine energy consumption, economize energy.Its longer service life.In addition, its electric conductivity is better, can save the material of 70 percent, reduce costs.
Accompanying drawing explanation
Fig. 1 is the schematic appearance of contact tip for carbon dioxide welding of the present utility model.
Fig. 2 is longitudinal cross-sectional schematic of contact tip for carbon dioxide welding of the present utility model.
Detailed description of the invention
Further illustrate the utility model below in conjunction with drawings and Examples, the content of embodiment is not as the restriction to protection domain of the present utility model.
As illustrated in fig. 1 and 2, contact tip for carbon dioxide welding of the present utility model comprises copper body.Described copper body comprises connected thick cylindrical body 1 and thin cylindrical body 2.Wherein, described thick cylindrical body 1 is provided with external screw thread, and like this, it can be threaded with welding equipment.
As shown in Figure 2, the center of described thick cylindrical body 1 is provided with a hollow cylinder stainless steel sleeve 5.Preferably, the thickness of described hollow cylinder stainless steel sleeve 5 is 0.2mm.Due to the existence of described hollow cylinder stainless steel sleeve 5, make it more wear-resisting.Meanwhile, its more resistance to burning, more not easy burn-out is made.Therefore, the service life of ignition tip is significantly improved.
The center of described hollow cylinder stainless steel sleeve 5 and described thin cylindrical body 2 is provided with cylindrical hole 3.Meanwhile, the end of described hollow cylinder stainless steel sleeve 5 is provided with the horn mouth 4 be connected with described cylindrical hole 3.During use, welding wire passes from described cylindrical hole 3 and horn mouth 4, realizes welding.Due to the existence of described horn mouth 4, make the end being in high temperature of in use welding wire more be not easy to contact with described hollow cylinder stainless steel sleeve 5, further increase its wearability and resistance to burning, further increase its service life.
Due to the existence of described hollow cylinder stainless steel sleeve 5, the length of described copper body can be shortened.In the utility model, preferably, the length of described copper body is 4.2cm.The diameter of described thick cylindrical body 1 is 4mm.The diameter of the large end of described horn mouth 4 is 1.2mm, and the diameter of small end is 0.8mm.Like this, the use amount of copper can be saved, approximately can save the material of 2/3rds, reduce costs, its price is significantly declined.Meanwhile, its conductive capability can be improved.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
