AI Technical Summary
The existing bumper punching and forming equipment lacks adjustment function and has poor adaptability. It cannot dynamically adjust the punching spacing, hole diameter and punching depth, which requires manufacturers to design special molds separately, increasing costs.
It adopts a worm gear transmission mechanism and hydraulic drive to achieve synchronous rotation of the inner and outer positioning plates. Combined with the adjustable structure of angle and stamping depth, it is compatible with a variety of bumper models, reducing the procurement and maintenance costs of special molds.
It improves the versatility and ease of adjustment of the equipment, reduces conversion costs, and can quickly adapt to bumper workpieces with different curvatures.
