通过制定合理的支承件多工位级进模具的排样方案,保证了支承件质量、模具强度和刚度;根据送料过程中制件形状的变化,修改导料板的结构形式,确保送料顺畅和导向准确;根据各工位工序特点,在不同工位抬起块上开导正销的引导孔或高压气孔,使得抬起块具有托料作用、引导导正销精确定位作用和排除废料作用;在不同工位上设置上拼块和中拼块,起到全长保护小凸模的作用;同时,弯曲工位上的嵌入式凸、凹模拼块,能方便及时修正弯曲角度。实践证明,该排样方案设计简化了多工位级进模具结构、定位准确、产品质量稳定。
According to the change of the shape of the parts during the feeding process, the structure of the guide plate is modified to ensure the smooth feeding of the feeding plate and ensure the quality of the supporting plate. Guide accurate; according to the characteristics of the process at each station, lift the block in different positions open pilot positive guide hole or high-pressure air hole, making the lift block has the role of care material, guide guide pin accurate positioning and eliminate the role of waste; Different workstations are arranged on the block and in the block, play a full-length protection of the role of small punch; the same time, the bending station embedded convex, concave block, can facilitate timely correction of bending angle. Practice has proved that the layout design simplifies the multi-station progressive die structure, accurate positioning, product quality and stability.
