Abstract
Description
Technical Field
[0001] This utility model relates to the field of nickel-titanium wire processing technology, specifically to a surface polishing device for nickel-titanium wire. Background Technology
[0002] Nickel-titanium wire is widely used in many fields such as medical, aerospace, and electronics due to its excellent shape memory effect and superelasticity. However, during the production process, nickel-titanium wire may develop some minor imperfections, oxide layers, or uneven roughness on its surface. These surface defects can affect the performance and service life of the nickel-titanium wire.
[0003] Traditional polishing devices are designed with only one polishing head, which cannot achieve double-sided extrusion polishing of nickel-titanium wire. The nickel-titanium wire is prone to shaking, making it impossible to guarantee the flatness of the polished surface. It is also impossible to polish multiple surfaces simultaneously, resulting in low efficiency. During polishing, a lot of residue remains on the surface of the nickel-titanium wire. The polishing wheel generates high temperatures during long-term operation, which accelerates the wear of the polishing wheel. In addition, a lot of moisture remains on the surface of the nickel-titanium wire, and the moisture drips onto the worktable, causing contamination. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a surface polishing device for nickel-titanium wires, which has advantages such as high efficiency and solves the problems mentioned in the background technology.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] It should be noted that the hair dryer 8 is existing technology and is common knowledge to those skilled in the art, so it will not be elaborated here.

[0023] A second drive motor 15 is installed on the right side of the polishing chamber 7. The second drive motor 15 is equipped with a pulley via its output shaft. Two forward and reverse lead screws 18 are installed in the upper part of the polishing chamber 7. Each forward and reverse lead screw 18 is equipped with a pulley on its right end. A belt 16 is installed on each of the three pulleys. Each forward and reverse lead screw 18 is equipped with two lead screw slides 17. Two movable frames are installed at the lower end of each lead screw slide 17. A wheel frame 20 is installed inside each movable frame. Polishing wheels 19 are installed inside each wheel frame 20. A drive motor is installed at the front end of each polishing wheel 19.
[0024] Each of the mobile frames is equipped with a water tank 21 at its lower end and a water spray pipe 22 at its upper end. Multiple small pipes are attached to the front of each water spray pipe 22, through which clean water from the water tank 21 is discharged to clean the residue on the surface of the nickel-titanium wire and to cool the multiple polishing wheels 19. A collection trough 3 is slidably installed on the front left side wall of the fixed frame 4. The upper end of the collection trough 3 is connected to the bottom end of the polishing chamber 7. A filter screen trough 14 is installed inside the collection trough 3. A handle is located in the middle of the left side wall of the collection trough 3, and a drain pipe with a valve is located at the lower left side wall of the collection trough 3. Wastewater flows into the collection trough 3, and residue falls onto the surface of the filter screen trough 14 for collection. The wastewater is then discharged through the drain pipe. A moisture-proof board 2 is installed on the upper end of the tabletop 1 to prevent moisture from entering the surface of the tabletop 1. Adsorption: A first guide wheel 9 is installed on the upper middle part of the left side wall of the support plate, and a second guide wheel 10 is installed on the lower middle part of the left side wall of the support plate. A first drive motor 11 is installed on the front part of the left side wall of the support plate. A take-up wheel 12 is installed on the first drive motor 11 through the output shaft. When the first drive motor 11 is started, the take-up wheel 12 is driven to rotate through the output shaft to automatically collect the nickel-titanium wire. The first guide wheel 9 and the second guide wheel 10 can straighten the nickel-titanium wire and avoid bending. A curved tube is installed on the rear part of the left side wall of the support plate. A blower 8 is installed at the lower end of the curved tube. When the blower 8 is started, the surface of the nickel-titanium wire is dried to reduce the dripping of residual nickel-titanium wire onto the table 1 and avoid contamination of the table 1. Columns 13 are installed at the four corners of the lower end of the table 1. There are four columns 13 to support the table 1.
[0025] The working principle of this utility model is as follows: The device is placed at the location where the work is to be performed, the power is connected, and the device is kept powered. The nickel-titanium wire is wound onto the placement wheel 5, with the tip of the wire entering the polishing chamber 7. The second drive motor 15 is started, and its output shaft drives the pulley to rotate. The belt 16 drives the pulleys on both sides to rotate, causing the two forward and reverse lead screws 18 to rotate. This causes the lead screw slide 17 to move inward, thereby moving the two polishing wheels 19 inward. The drive motor is then started, causing the two polishing wheels 19 to rotate, polishing the nickel-titanium wire. This achieves double-sided extrusion, preventing the nickel-titanium wire from shaking and ensuring the flatness of the polished surface. Simultaneously, multiple surfaces are polished. Polishing improves efficiency. Clean water in the water tank 21 is discharged through a small pipe to clean the residue on the surface of the nickel-titanium wire and cool the surface of the polishing wheel 19. The wastewater generated flows into the collection tank 3, and the residue falls onto the surface of the filter screen 14 for collection. The wastewater is discharged through the drain pipe. The nickel-titanium wire passes through the polishing chamber 7 and is guided to the second guide wheel 10. The blower 8 is started to dry the surface of the nickel-titanium wire. Then it is guided to the first guide wheel 9 and wound onto the take-up wheel 12. The first drive motor 11 is started, and the take-up wheel 12 is driven to rotate through the output shaft to automatically collect the nickel-titanium wire. The first guide wheel 9 and the second guide wheel 10 can straighten the nickel-titanium wire to avoid bending and ensure flatness.
