Description

Background
Various products of the nickel-titanium memory alloy wire material in the nickel-titanium shape memory alloy product after heat treatment and shaping occupy great proportion, and the nickel-titanium shape memory alloy wire material is often applied to medical appliances such as orthodontic wires, vascular stents, non-vascular stents, cardiac stents, occluders and the like. The nickel-titanium shape memory alloy wire needs to be subjected to multiple times of heat treatment annealing in the drawing production to eliminate the processing stress of the nickel-titanium shape memory alloy wire, compact oxide skin is generated on the surface of the wire and appears black after annealing, and in order to improve the surface quality of the wire and the appearance of the wire, surface treatment is usually carried out between each heating time of drawing deformation and after drawing is finished to remove the oxide skin on the surface.
At present, the following three methods are generally adopted for removing the oxide skin on the surface of the nickel-titanium shape memory alloy wire material:
(1) pickling or electrochemical polishing, wherein the pickling usually adopts nitric acid, hydrofluoric acid and water to prepare a solution according to a certain proportion, the wire is immersed in the acid solution for a period of time, and then rinsing is carried out by using clear water; electrochemical polishing usually adopts electrochemical polishing solution containing certain acid liquid such as sulfuric acid, metal salt and additive, and nickel-titanium wire is used as an anode and is electrified by direct current to cause the wire and the polishing solution to generate electrochemical reaction so as to remove oxide skin. The two modes adopt an acid solution as a cleaning medium, relate to the use of a large amount of dangerous chemicals, can produce a large amount of waste acid liquid simultaneously, and the treatment cost is high, and environmental pollution is big.
(2) Mechanical polishing, patent CN112605745A discloses a nickel-titanium wire circumference fine polishing device. The method is easy to cause scratch on the surface of the wire, and simultaneously has large dust amount, and the nickel-titanium alloy micro powder has high activity and is easy to react with air to cause fire.
(3) The patent CN110093617A discloses a titanium wire cleaning method and a titanium wire cleaned by the method, and the method has the following problems in implementation: 1. the laser spot of single laser processing can only effectively cover about one third of the area of the circumference of the processed wire material facing the laser beam, and the wire material on the back surface can not contact the spot for processing; 2. when the wires subjected to the primary treatment are subjected to secondary treatment, a large number of areas can not be effectively cleaned, because the wires are twisted in the paying-off and taking-up processes; 3. by taking the reference of the method for removing the oxide skin on the surface of the wire, all the oxide skin can be removed after multiple times of treatment, but the problem that the size is smaller when a large number of areas of the wire are subjected to multiple times of laser treatment is found, and meanwhile, for the wire with the diameter smaller than 1mm, due to the input of excessive heat, the tissue of the wire is changed, and the performance is poor. In addition, the continuous laser cleaning technology can also arrange a plurality of laser cleaning heads around the silk material, makes the laser facula can cover the radial circumference of silk material, but the facula has the coincidence portion, can cause the local excessive washing of silk material, damages silk material surface. The lens of the laser head with the upward mirror surface or the horizontal direction in the plurality of lasers is easy to stick dust, so that laser beams burn the lens, and the service life of the machine is shortened.
Therefore, the invention is needed to provide a device for removing the oxide skin on the surface of the nickel-titanium memory alloy wire and a using method thereof, which can remove the oxide skin on the surface of the nickel-titanium memory alloy wire by laser with high efficiency, cleanness and no matrix damage, so as to solve the technical problems.
