Description

Technical Field

[0001] The utility model belongs to the technical field of interventional guide wire processing, in particular to a drawing processing mechanism for a stainless steel wire. Background Art

[0002] Interventional guidewires usually refer to guidewires used in medical interventional diagnosis and treatment, such as cardiovascular intervention, neurological intervention, hepatobiliary intervention, etc. These guidewires are usually made of special materials such as nylon, polyethylene, ethylene fluoride and stainless steel wire, which have the characteristics of flexibility, folding resistance, corrosion resistance and biocompatibility.

[0003] Stainless steel interventional guide wires require a drawing processing mechanism during the production process, but the existing stainless steel interventional guide wire drawing processing mechanism is composed of an external mold and a stretching mechanism. The stainless steel interventional guide wire raw material passing through the external mold is pulled by the stretching mechanism so that it is squeezed by the external mold to become a stainless steel interventional guide wire of specified specifications. However, it does not have the function of evenly applying the drawing oil. Manual application is not only inefficient but also easily causes some positions to be unapplied. When using an oil spray nozzle, the oil spray volume is large, which makes it difficult to recover the drawing oil, affecting the drawing effect of the interventional guide wire.

[0004] To this end, we provide a stainless steel wire drawing processing mechanism to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a drawing processing mechanism for stainless steel wire. By coordinating an oiling component and a filtering component, the utility model solves the problem of uneven application of drawing oil in the drawing processing mechanism for stainless steel wire in the prior art, which easily leads to surface scratches and breakage of the interventional guide wire during the drawing process.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
