AI Technical Summary
Existing epoxy molding compound pipe cutting equipment is prone to chipping, delamination and micro-cracks during the cutting process, especially for large-diameter or thin-walled pipes. In addition, the equipment is expensive or produces toxic fumes. Insufficient clamping and feeding mechanisms result in poor cut flatness.
The two-step gradient cutting process of external circumferential cutting and internal cutting is adopted. Combined with the circumferential rotation of the pipe, constant friction is provided by synchronous rotating rollers and bonding extrusion frame to transfer stress concentration points to the inner side of the pipe wall. The inclined structure of the cutting blade is used to realize mechanical linkage to deflect the blade, which simplifies the equipment structure.
It significantly improves the smoothness and flatness of pipe cuts and the yield rate, reduces equipment costs, avoids the risk of mechanical interference and equipment damage, and ensures a smooth cutting process.
