This 3-machine linkage line integrates an automatic feeding manipulator, two linkage manipulators, and three hydraulic presses. It is specifically designed for the production of steel backs for bus brake pads/shoes. The system enables fully automated processing of steel back blanks through multiple operations including punching, fine trimming, edge removal, edge pressing, and leveling.
Equipment Features：
Multi-machine linkage saves labor and significantly improves production efficiency.
Integrated design with automated material handling reduces manual intervention and minimizes operational errors.
Equipped with safety protection features to avoid workplace injury risks.
Flexible configuration – can be expanded to accommodate 3 or 4 machine linkages based on production requirements.
High precision and consistency – hydraulic systems provide the necessary force to shape materials accurately, ensuring each back plate is consistent in size and strength.
