A kind of processing method of high precision U-shaped titanium nail

Abstract

The invention relates to a processing method for a high-precision U-shaped titanium nail. The method comprises the following steps that a straightening mechanism is manufactured by utilizing cork materials; titanium wires are conveyed in the straightening mechanism, the rotating speed of a straightening raw is controlled to be 2800-3200 revolutions / min, the wire discharging speed is 2-3.5 circles / min, the wire winding speed of a wire winding mechanism is controlled to be 6-7circles / min for wire winding; and the titanium wires wound by the wire winding mechanism are convoyed into a cutter die,a die core is attached to cutters, after a forming mechanism presses down, a pressure spring and a pre-pressing block press the titanium wires tightly, then double cutters on the two sides act to cuttitanium wires on the two sides of the cutter die at the same time, the titanium wires are bent and formed, and a titanium nail with a U-shaped structure is formed. Compared with the prior art, the process of one-time punching forming has the advantages that the process is greatly simplified, the production efficiency is improved, and the processing mode is unique, so that products are greatly improved in terms of quality, performance and processing flexibility.

Description

technical field [0001] The invention relates to the field of processing and manufacturing, in particular to a processing method of a high-precision U-shaped titanium nail. Background technique [0002] Medical titanium nails, disposable consumable products, are used in medical staplers to replace traditional manual suture products in medicine. The product material is titanium, and the main structure is U-shaped. [0003] When the existing U-shaped titanium nails are produced and processed, the spring winding method is used to form the four sides first, and then the mechanical edging process is used to make the U-shaped and silk feet of the titanium nails. However, the existing processing technology has the following disadvantages: 1. The two-way molding process has complicated procedures. 2. High material loss, more than 25%. 3. This forming method cannot guarantee the straightness of the titanium wire body and the two wire feet, and there is a certain inclination, which ...

Problems solved by technology

However, the existing processing technology has the following disadvantages: 1, the two-way molding process, the process is complicated

2. High material loss, more than 25%

3. This forming method cannot guarantee the straightness of the titanium wire body and the two wire feet, and there is a certain inclination, which will affect the guiding performance of the wire feet

4. The edging process of the angle of the silk foot, the angle consistency cannot be guaranteed accurately, and there will be defects such as long and short angles, sharp angle differences, etc., which seriously affect the puncture performance
