Commodity name: Projection welding machine
Commodity ID: B-025

Equipment introduction:

Shoe reinforced plate projection welding machine This special machine is suitable for welding brake shoe reinforced plate.

Features:

1. The shoe reinforcement plate projection welding machine adopts an intermediate frequency controller, and the welding current is close to full DC. Since there is no obvious peak current, the size of the nugget expands steadily, there is almost no spatter, the welding quality is stable, and the thermal efficiency is high. Compared with the industrial frequency welding machine, the welding current of the intermediate frequency welding machine can be reduced by 40%, and the service life of the electrode is greatly extended;
2. The response speed of intermediate frequency welding is only 1/20 of that of power frequency welding, the current can reach the set value faster, the parameters can be analyzed more accurately, and the welding quality control is more precise;
3. Intermediate frequency welding three-phase load balance, high power factor (about 0.9), energy saving. For two-phase industrial frequency welding machines, it is difficult to ensure the balance between phase voltages and low power factor (about 0.6) when working, and it is difficult for three-phase industrial frequency welding machines to achieve constant current output;
4. The intermediate frequency welding machine is suitable for welding various materials and dissimilar metals, such as aluminum alloy, stainless steel, high-strength steel plate and other materials. In addition, for the welding of galvanized sheets and ordinary multilayer sheets, the welding quality is much higher than that of industrial frequency welding machines;
5. The product electrode adopts a detachable method, which is convenient to replace the product electrode and saves costs;
6. The product is pressed in the form of a cylinder, which is clean;
7. The pressurized welding cylinder adopts Taiwan Jiuyi wear-resistant sealing ring and a two-stage pressurization system. This structure can increase the stability of welding and improve the durability of the welding cylinder;
8. In the past, the workers held the product for welding, and the joint between the reinforcing plate and the product would be displaced, the size deviation was large, and it was unsafe; now it is only necessary to put the product and the reinforcing plate on the fixture for projection welding, welding Beautiful, standard size;

9. Loading and unloading, convenient and simple replacement of molds, saving time.

10. Easy to operate and understand.
