Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical guide wire processing equipment, in particular to a drawing device for processing stainless steel wires. Background Art
[0002] Medical interventional guidewires are usually made of metal or polymer materials. They are flexible and strong and can navigate in narrow blood vessels or tissue channels. Stainless steel medical interventional guidewires are an important material used in medical devices and usually need to be processed to achieve the required specifications and performance requirements. One of the common processing methods is processing through drawing equipment. In the processing of stainless steel medical guidewires, the stainless steel material must first be pre-processed, such as cutting the raw materials into appropriate lengths and performing surface treatment. The pre-processed material is then placed in the feeding mechanism of the drawing equipment, and the material delivery speed and strength are controlled by traction and pressure.
[0003] However, in the prior art, the stainless steel medical guide wire drawing equipment passes through multiple continuous drawing dies during the processing, and the diameter of each module gradually decreases. When the stainless steel guide wire passes through each module, it will undergo plastic deformation, reduce its diameter, and extend its length, so as to perform plastic processing. However, the distance between each set of drawing dies is fixed. When the guide wire enters the drawing dies, the heat generated by friction is relatively large. When the heat on the surface of the guide wire cannot be reduced, it enters the next set of drawing dies, which easily causes the guide wire to be over-stretched and uneven. The commonly used solution is to reduce the winding speed, but the reduction in winding speed will affect the processing efficiency.
[0004] To this end, we provide a drawing device for stainless steel wire processing to solve the above problems. Utility Model Content
