The aim of the invention is to provide a welding head of a point electric welding machine with low production cost and capable of saving refractory metal resource. The welding head of the invention is stable and reliable when welding, and is an environment protection product.
Description
Technical field
The utility model relates to a kind of welding consumptive material, especially a kind of electric spot-welding machine soldering tip.
Background technology
The electric spot-welding machine soldering tip is topmost instrument and a consumptive material in the welding technology, and the electric spot-welding machine soldering tip of prior art is made up of two electrodes, and this two electrode is arranged in parallel, and insulating barrier is arranged in the middle of two electrodes, and utilize bonding or technique for riveting with two electrode engagement together.As shown in Figure 1: 1,2 is electrode, and 3 is insulating barrier.Because the temperature of solder joint is higher, each electrode makes with the whole refractory metal of a joint, and its manufacturing cost is higher, gives and adopts the manufacturer of this welding procedure to cause sizable burden on the cost; And welding itself to soldering tip have the high temperature requirement only for soldering tip front end face very small percentage, thereby existing plumb joint is extremely wasted the refractory metal resource, the cost of this waste is married again in the producer that adopts this technology, and allow the people that its production cost is given birth to fear, seriously hinder the popularization and the development of electric spot welding technology.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model is the electric spot-welding machine soldering tip that a kind of low cost of manufacture is provided, can saves the refractory metal resource.
The technical scheme that its technical problem that solves the utility model adopts is: include two electrodes, this two electrode is arranged in parallel, insulating barrier is arranged in the middle of two electrodes, it is characterized in that: each electrode includes the electric current guide portion of back and the heating portion of front, the electric current guide portion is made with ordinary metallic material, the refractory metal material manufacturing of heating portion, electric current guide portion and heating portion link together becomes an electrode.
The beneficial effects of the utility model are: with low cost, save the refractory metal resource, reliable and stable during welding, be a kind of environment-friendly products.
