AI Technical Summary
The existing stamping equipment base is inadequate in preventing the metal clips from springing back, causing the shape and size of the stamped parts to deviate from the ideal shape of the mold design, affecting the forming accuracy and product quality.
The design employs a combination of adjustable mold wall, return spring, and lifting mechanism. The adjustable mold wall constrains the side of the metal clip, and the receiving block and return spring limit its rebound. The transmission mechanism adjusts the mold wall tilt angle to achieve negative angle stamping. Combined with the lifting mechanism, the position of the limit plate can be flexibly adjusted to meet the needs of metal clips of different shapes and sizes.
It effectively controls stamping deformation, improves forming accuracy and product quality, adapts to the stamping needs of metal clips of different shapes and sizes, and enhances the versatility and stamping accuracy of the equipment.
