Blank-holding device for rapid trial production of medium and large stamping parts

Abstract

The invention relates to an edge pressing device of a quick trial-manufacturing die for middle and large-sized stamping parts and is characterized in that: an edge pressing ring is fixed on an edge pressing frame through planar parts at both ends of the edge pressing ring; the other two side bottom faces of the edge pressing ring are connected with supporting rods through screw threads of an inner hole of a platform; the position of the inner hole of the platform is coaxial with the position of a pressing bed mandril hole; the supporting rods are ejected on the bottom face of the inner hole of the platform of the edge pressing ring and vertical to the planes at both ends of the edge pressing ring; the supporting rods are in threaded connection with a height adjustment sleeve; the bottom face of the height adjustment sleeve is leveled with the bottom face of the edge pressing frame; the height adjustment sleeve is locked by using a locking nut; and the edge pressing ring has light weight, simple structure, low production cost and short manufacturing period. In different middle and large-sized stamping part drawing, forming and edge-pressing devices, only the edge pressing ring is needed to be redesigned and reprocessed and the edge pressing frame is not needed to be reprocessed; the supporting rods can be processed into different heights; and by aiming at different edge pressing rings, only the supporting rods having the proper heights are selected and the height adjustment sleeve and the locking nut are used to finish the manufacturing of the edge pressing device.

Description

technical field [0001] The invention relates to a rapid trial-manufacturing mold edge-holding device for medium and large stamping parts, which belongs to the field of rapid molds. Background technique [0002] The drawing forming dies for small and medium-sized stamping parts, especially medium and large stamping parts, are bulky, heavy, consume a lot of materials, have long design and manufacturing cycles and high costs. Therefore, the drawing dies for small and medium batches of medium and large stamping parts should be simplified as much as possible, and suitable rapid dies should be developed with as little investment and short cycle as possible under the premise of satisfying the quality of parts. [0003] Rapid molds include zinc-based alloy molds, resin molds, cast iron molds and steel molds. Due to their low strength and hardness, the first two molds are suitable for the trial production of thin plates and inner surface parts with relatively low quality requirements...
