Automatic brake shoe roll Spot Welding Machine: A solid backing for braking safety

In the automotive braking system, the Brake shoes, as the core component directly acting on the brake drum, their Welding quality is directly related to the braking performance and driving safety of the vehicle. The Automatic Brake Shoe Roll Spot Welding Machine is an efficient welding equipment tailor-made for this key component. It continuously performs point welding on the surface of the brake shoes through roller-type electrodes, forming a uniformly distributed group of welding points. This not only ensures a firm connection between the brake shoes and the friction plates but also meets the welding requirements of the arc-shaped structure of the brake shoes, laying a solid foundation for the stable operation of the braking system.

Compared with other welding equipment, this automatic roll spot welding machine has obvious advantages in the manufacturing of brake shoes. The Friction Welding Machine achieves connection by generating heat through friction. However, the axial pressure during welding is prone to deform the arc-shaped surface of the brake shoe, affecting the fit during braking. Although the Spot Welding Machine can complete single-point welding, on components like brake shoes that require uniform distribution of multiple weld points, manual movement and positioning are not only inefficient but also difficult to ensure the consistency of the weld point spacing. The Butt Welding Machine is suitable for the butt welding of rods, but it cannot meet the planar connection requirements between the brake shoes and the friction plates. The continuous weld seams formed by the Seam Welding Machine will increase the weight of the brake shoes and are not conducive to the heat dissipation of the friction plates, which is contrary to the lightweight and heat dissipation requirements of the braking system. Laser Welding Machine for Steel Ring focuses on the circular welding of steel rings, but its technical parameters do not match the material and welding process of the brake shoes. The Stud Welding Machine is only used for the fixation of studs and is unable to undertake the welding work of the main structure of the brake shoes.

The Automatic Brake Shoe Roll Spot Welding Machine, in view of the structural characteristics of the brake shoe, adopts automated roller feeding and current control technology. It can quickly complete the continuous welding of multiple weld points on the arc-shaped surface, with uniform distribution and consistent strength of the weld points. It effectively enhances the overall rigidity and service life of the brake shoes. Its precise pressure regulation function can prevent damage to the friction plates during the welding process. Meanwhile, the high-speed welding rhythm significantly enhances production efficiency, providing a reliable guarantee for the high-quality manufacturing of automotive braking systems and becoming an indispensable key equipment in the production process of brake shoes.

Roll spot welding machine for brake shoes

dvantage:	Machine body of thick steel sheet, not easy to deformation
	Microcomputer control, accuracy and steady
	Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long time welding, big output power. The useful lifetime is longer, noise is smaller, structure is more compact and reasonable.
	Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.
	Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.
	Quality is stable, failure rate is low, therefore machine life is longer
