Positioning assembly for heart stent metal mold processing machine tool

Abstract

The present invention discloses a positioning assembly for a heart stent metal mold processing machine tool. The positioning assembly comprises a base disc, a driving pair and a vertical frame which are fixedly arranged above the base disc, and the base disc is rotationally connected with a first horizontal transmission gear disc, a second horizontal transmission gear disc and an intermittent gear through a rotating shaft; a first gear transmission roller and a second gear transmission roller are arranged above the base disc, an eccentric rod is fixedly arranged on the side face of the vertical transmission gear disc, and a transmission rod is connected between the eccentric rod and the connecting rod in a transmission manner. According to the present invention,by adopting a circulating up-and-down extrusion forming structure, the annular extrusion teeth drive a mold circular ring in an annular groove to bend, and by adopting a clearance transmission rotating structure, the annular extrusion teeth conduct extrusion forming on the mold circular ring, and meanwhile by adopting a co-power linkage transmission structure, the mold circular ring is extruded and formed to be of an uneven structure after being subjected to linkage transmission, and meanwhile, convenience is brought to disassembly and material taking after being formed at a lantern ring.

Description

technical field [0001] The invention relates to the technical field of mold equipment for heart stent processing, in particular to a positioning assembly for a heart stent metal mold processing machine tool. Background technique [0002] Cardiac stents, also known as coronary artery stents, are commonly used medical devices in cardiac interventional operations. They have the function of dredging arteries. [0003] Heart stents are widely used in modern medical procedures. However, the existing heart stent molds need to be bent and stretched to the formed ring mold during the production process. However, in the actual production process, the production extrusion of the ring mold The compression efficiency is low and the accuracy is poor. At the same time, the multi-stage driving mechanism is required to drive the transmission separately during the processing of the ring mold, which may easily cause the accumulation of angle errors during the ring processing of the heart stent...

[0003] Heart stents are widely used in modern medical procedures. However, the existing heart stent molds need to be bent and stretched to the formed ring mold during the production process. However, in the actual production process, the production extrusion of the ring mold The compression efficiency is low and the accuracy is poor. At the same time, the multi-stage driving mechanism is required to drive the transmission separately during the processing of the ring mold, which may easily cause the accumulation of angle errors during the ring processing of the heart stent mold, resulting in errors and deformation of the mold after extrusion molding. question
