Medical titanium alloy forging calibration punch press

Abstract

The invention belongs to the technical field of medical titanium metal forging and relates to a medical forging for human body implantation, in particular to a medical titanium alloy forging calibration punch press. The medical titanium alloy forging calibration punch press comprises a punch press body, a cushion block base, a punch and a crank, wherein the cushion block base is arranged at the lower part of the punch press body, and the punch is arranged at the upper part of the punch press body and is opposite to the cushion block base; and the crank is used for controlling the punch to movein a vertical direction. The medical titanium alloy forging calibration punch press is characterized in that the punch is a replaceable punch and is fixed to the punch press body through a punch fastening structure, and a lower cushion block matched with the punch is fixedly arranged on the cushion block base through a lower cushion block fastening structure; and the punch and the lower cushion block can be replaced according to products and can be fast disassembled and assembled through the punch fastening structure and the lower cushion block fastening structure respectively. Different types of products are subject to calibration treatment on one set of equipment, accumulated errors or influences on the surface characteristics of products are not prone to being generated. Moreover, thespringback angle of the punch press can be accurately controlled, and the fine process structure of a medical titanium alloy forging is not destroyed.

Description

technical field [0001] The invention belongs to the technical field of medical titanium metal forging, relates to medical forgings implanted in human body, in particular to a medical titanium alloy forging correction punch. Background technique [0002] Medical titanium alloy belongs to a kind of memory metal, which is easy to rebound and deform after forging, especially for thin, narrow, thin and long bone plates. The high precision required for medical forgings for human implants is contradictory. [0003] In the actual production process, large-tonnage forming equipment is usually used to correct the springback deformation after forging and pressing of medical titanium alloys with corresponding calibration dies. Although such a treatment method has high precision, it needs to design and produce corresponding calibration molds for different batches of products. This approach makes the entire process inefficient, high in energy consumption, and high in product costs, thus ...

Problems solved by technology

Although this processing method has high precision, it needs to design and produce corresponding calibration molds for different batches of products. This method makes the entire process inefficient, high in energy consumption, and high in product costs, thus indirectly leading to increased medical costs.

[0004] In order to ensure the accuracy and reliability of correcting the structural size of the mold, the mold is mostly made of cemented carbide steel with high strength and hardness. However, when used with large-tonnage forming equipment, it will often cause damage to the surface of medical titanium alloy forgings and destroy the surface. smoothness, even the product is scrapped due to damage to the surface structure; at the same time, long-term use of the calibration mold will cause deformation in the part where the force is concentrated, resulting in a certain accumulation of errors in the calibrated product, which affects the yield

[0005] Furthermore, medical titanium alloy forgings often need to cooperate with the bones and joints in the human body. The surface of the product will be designed with a variety of small ribs, grooves, grooves and other technical structures. In the actual production process, large-tonnage forming equipment is used for correction. The elastic angle will cause certain damage to the small process structure, reduce the yield of the product, and also increase the overall cost of the product.
