AI Technical Summary
Technical Problem
In the traditional inward convex punching process of car seat pipe fittings, the punch-formed holes are prone to quality problems such as uneven forming surfaces and burrs, and too long force arms can easily cause the pipe fitting to break, and the yield rate is low.
Method used
A molding mold including an upper bottom plate, a lower bottom plate, and a mandrel is designed. Through the cooperation of the mandrel fixing seat and the elastic components, extruded punching is realized, buffering the downward pressure of the hit block, and ensuring that the punching hole is flat.
Benefits of technology
The punching is flat, the yield rate is improved, and the problem of poor molding and pipe fittings breakage is avoided in traditional impact punching.
