Titanium clip bending, cutting and forming mechanism

Abstract

The invention discloses a titanium clip bending, cutting and forming mechanism which comprises a jacking assembly, a first bending assembly, a second bending assembly, a cutting assembly and a rack, and the jacking assembly, the first bending assembly, the second bending assembly and the cutting assembly are arranged on the rack. The rack comprises a first fixing plate, a first connecting plate, second connecting plates, a cross beam and a fixing frame, the two ends of the cross beam are connected with the second connecting plates respectively, the second connecting plates are fixedly arranged on the upper sides of the first connecting plates, the first connecting plates are fixedly arranged on the first fixing plate, and the fixing frame is arranged on one side of the first fixing plate; the jacking assembly penetrates through the first connecting plate, the first bending assembly is arranged on the second connecting plate, and the second bending assembly is arranged on the fixing frame. The cylinders can be controlled by a PLC (programmable logic controller) in the prior art, and the titanium clamp manufacturing device is high in automation degree, high in titanium clamp manufacturing efficiency, small in manufacturing error and good in manufactured titanium clamp straightness.

Description

technical field [0001] The invention relates to the processing field of titanium clips, in particular to a bending, cutting and forming mechanism of titanium clips. Background technique [0002] Traditional vessel closures are usually ligated with fusible sutures, which is laborious and prolongs operative time. The use of titanium clip closure not only can greatly shorten the operation time, but also is easy and convenient to operate and use. [0003] The titanium clip closer is composed of the main parts such as the needle clip forceps, the titanium clip, the needle storage tube and the operating handle. Its working principle is: put the needle forceps into the blood vessel to be closed, pinch the infusion needle handle, at this time the titanium clip is sent to the needle forceps, and then pinch the needle pressure handle until the instrument sends out "click, click". Just make a sound, which indicates that both the needle rod and the titanium clip are ready to fire, and...

AI Technical Summary

Problems solved by technology

The main manifestations are: the concave surface of the inner closed surface of the titanium clip is more complicated to make, and at the same time, the material accumulation occurs due to the deformation of the bending part of the needle during the operation, resulting in stress concentration and rebound phenomenon, so that the titanium clip cannot be closed firmly.
