Description

Technical Field

[0001] The present invention relates to the technical field of medical component processing, and particularly relates to a flattening tooling for medical stainless steel rods. Background Art

[0002] Due to its excellent strength and toughness, anti-bending fatigue strength, good processing performance, low cost and other advantages, stainless steel is widely used in orthopedic implant products such as artificial joints (hip, knee, shoulder, ankle, elbow, wrist, finger joints, etc.), bone trauma products (intramedullary nails, plates, screws, etc.), spinal orthopedic internal fixation systems, as well as orthodontic products (brackets, bands, orthodontic wires, implants for anchorage) and interventional therapy device products such as cardiovascular stents and other medical devices. 316L, 317L, 304, etc. are typical representatives of medical stainless steel.

[0003] In order to produce medical stainless steel into corresponding medical components, after the stainless steel rod is produced, it is necessary to extrude the stainless steel rod into a plate shape for convenient subsequent processing. In the prior art, a pressure roller is generally used for direct extrusion, but the edges of the extrusion are uneven and need to be cut before use, resulting in relatively serious waste of medical stainless steel materials. Therefore, we propose a flattening tooling for medical stainless steel rods to solve the above problems. Summary of the Invention
