Description
Technical field
The utility model belongs to nut projection welding technical field, relates to a kind of projection welding blowning installation.
Background technology
Due to the strong specification of the popular use of current projection welding parameter, in production process, ubiquity splashes excessive situation, thus causes the first-time qualification rate of projection welding back nut screw thread not reach 100%, and need increase full inspection operation together and just can dispatch from the factory, cost is high.
Although existing bottom electrode blowing techniques improves the first-time qualification rate of projection welding back nut screw thread to a certain extent, after reality uses, statistics, cannot reach the qualification rate of 100%.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, a kind of projection welding blowning installation is provided, for the projection welding process of project-welding nut, projection welding back nut screw thread first-time qualification rate can greatly be improved, and change simple and easy, efficiency is higher, do not affect production efficiency, cost of manufacture is cheap.
The technical scheme realizing above-mentioned purpose is: a kind of projection welding blowning installation, comprises projection welding top electrode, joint, tracheae, external gas source and magnetic valve, wherein:
A screwed hole is offered in the side of described projection welding top electrode, and this screwed hole is communicated with the electrode cavity of described projection welding top electrode;
Described joint screw thread is connected in the screwed hole of described projection welding top electrode;
One end of described tracheae is connected with described joint, and the other end is connected with the output of described external gas source;
Described magnetic valve is arranged on described tracheae.
Above-mentioned a kind of projection welding blowning installation, wherein, the model of the screwed hole of described projection welding top electrode is M6 screwed hole.
The technical scheme of projection welding blowning installation of the present utility model, compared with prior art, have reasonable in design, structure is simple, the feature such as easy to use, improve production efficiency, reduce production cost, projection welding back nut screw thread first-time qualification rate can greatly be improved, and change simple and easy, efficiency is higher, do not affect production efficiency, cost of manufacture is cheap.
Accompanying drawing explanation
Fig. 1 is the structural representation of projection welding blowning installation of the present utility model.
Detailed description of the invention
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, its detailed description of the invention is described in detail:
Consult Fig. 1, embodiment of the present utility model, a kind of projection welding blowning installation, comprise projection welding top electrode 1, joint 2, tracheae 3, external gas source 4 and magnetic valve 5.
It is the screwed hole of M6 that a model is offered in the side of projection welding top electrode 1, and this screwed hole is communicated with the electrode cavity 11 of projection welding top electrode 1, and in the weld state, the bossing of nut 6 is placed in the electrode cavity 11 of projection welding top electrode 1; Joint 2 is threaded in the screwed hole of projection welding top electrode 1; One end of tracheae 3 is connected with joint 2, and the other end is connected with the output of external gas source 4; Magnetic valve 5 is arranged on tracheae 3.
The operation principle of projection welding blowning installation of the present utility model is: offering a model at projection welding top electrode 1 is the screwed hole of M6, and this screwed hole is communicated with the electrode cavity 11 of projection welding top electrode 1, and be equipped with a tracheae 3, air-blowing quantity is controlled by magnetic valve 5.When nut is produced, when projection welding top electrode 1 falls to nut 6 from upper initial point and is compacted to trigger equipment cylinder forging and stamping function, magnetic valve 5 will accept this signal, the air-blowing quantity of 0.2Mpa to be discharged in whole projection welding process by tracheae 3 and maintains 1 second, make to produce to splash during production to fly out from the gap between the electrode cavity 11 and the bossing of nut 6 of projection welding top electrode 1, thus do not stick in nut 6.
The course of work of projection welding blowning installation of the present utility model is:
1, before producing, first projection welding top electrode 1 is fixed on electrode stem 7;
2, reusable connector 2 is coupled together by screw thread and projection welding top electrode 1, is then connected with external gas source 4 by joint 2 by tracheae 3, and is arranged on tracheae 3 by magnetic valve 5;
3, when nut 6 is produced, the air-blowing quantity of 0.2Mpa will be discharged in whole projection welding process by the screwed hole of projection welding top electrode 1 by tracheae 3 and maintain 1 second by external gas source 4.
In sum, projection welding blowning installation of the present utility model is by the checking of actual production two months nearly 60,000 parts, projection welding back nut screw thread first-time qualification rate reaches 99.99%, greatly improve projection welding back nut screw thread first-time qualification rate, have reasonable in design, structure is simple, the feature such as easy to use, improve production efficiency, reduce production cost.
Carry out introducing explanation to projection welding blowning installation provided by the utility model above, apply specific case herein to set forth embodiment of the present utility model, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model, as long as in spirit of the present utility model, to the change of the above embodiment, modification all will drop in Claims scope of the present utility model.
