Technical Field
[0001] This utility model relates to the field of preparation equipment technology, and in particular to a nickel-titanium alloy wire preparation device with superelastic memory function. Background Technology
[0002] In the field of nickel-titanium alloy wire manufacturing, with continuous technological advancements, the requirements for the quality and performance of nickel-titanium alloy wires are becoming increasingly stringent. Nickel-titanium alloy wires with superelastic shape memory function have wide applications in many high-end fields such as aerospace, medical devices, and electronic equipment; their surface quality and precision directly affect the performance and reliability of subsequent products.
[0003] Current nickel-titanium alloy wire preparation equipment has many limitations. For example, in the grinding and polishing stage, most existing equipment cannot be flexibly adjusted according to the diameter of the nickel-titanium alloy wire. When faced with nickel-titanium alloy wires of different diameters, the fixed grinding structure cannot achieve a grinding operation that is compatible with them, resulting in poor grinding results. Summary of the Invention
[0004] The purpose of this invention is to provide a device for preparing nickel-titanium alloy wire with superelastic memory function, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a mounting frame, a pair of fixing rings on the mounting frame, an adjustable polishing component between the two fixing rings, L-shaped support rods symmetrically arranged on the front and rear sides of the mounting frame, a through shell on the top of the L-shaped support rod, threaded cylinders symmetrically arranged on both sides of the through shell, and a positioning clamp inside each threaded cylinder.
[0006] As a preferred embodiment of this utility model, the adjustable polishing assembly includes a ring body, with movable grooves at the top and bottom of the ring body. A pair of polishing blocks are symmetrically arranged inside the ring body, and first screws are symmetrically arranged at the upper and lower ends of the polishing blocks. The two first screws are respectively inserted into the two movable grooves and are fixed together by nuts. Two rings of transmission teeth are arranged on the outer side of the ring body, and the two rings of transmission teeth are located on both sides of the movable grooves.
[0007] As a preferred embodiment of this utility model, a triangular support is provided on one side of one of the L-shaped support rods, a motor is provided on the triangular support, and a gear is provided on the transmission end of the motor, the gear meshing with two rings of transmission teeth.
[0008] As a preferred embodiment of this utility model, the inner wall of the fixing ring is provided with a sliding groove, and the two sides of the ring body are symmetrically provided with sliding edges, which are disposed in the sliding groove.
[0009] As a preferred embodiment of the present invention, the positioning clamp includes a second screw, the second screw being threaded inside a threaded cylinder, a bearing being provided at the top of the second screw located within the ring body, an auxiliary clamping block being provided outside the bearing, and a rotating wheel being provided at the end of the second screw away from the auxiliary clamping block.
[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0011] This invention features an adjustable polishing assembly. The polishing block is installed in the moving groove of the ring body via a screw and nut. By loosening the nut, the position of the polishing block can be easily adjusted along the moving groove to accommodate nickel-titanium alloy wires of different diameters, enabling flexible polishing operations. The motor drives the gear to mesh with the transmission teeth on the outer side of the ring body, causing the ring body to drive the polishing block to rotate at high speed, polishing the outer wall of the nickel-titanium alloy wire. This efficient polishing method can effectively remove impurities, scratches, and other defects from the surface of the nickel-titanium alloy wire, improving its surface smoothness and meeting the stringent requirements of the super-elastic memory function for material surface quality.
[0012] This invention, by setting threaded cylinders and positioning clamps on both sides of the casing, rotates the second screw by turning the rotating wheel, and moves the auxiliary clamping block inward through the bearing to limit the movement of the nickel-titanium alloy wire. This effectively avoids the problem of the nickel-titanium alloy wire running off-center during winding, ensuring neat and tight winding, improving the quality and stability of nickel-titanium alloy wire winding, and reducing product defects and subsequent processing difficulties caused by non-standard winding.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0021] like Figures 1-6 As shown, the present invention proposes a nickel-titanium alloy wire preparation device with superelastic memory function, which mainly consists of a mounting frame 1, a fixing ring 10, an adjustable polishing component 2, an L-shaped support rod 12, a through-shell 13, a threaded cylinder 14, and a positioning clamp 3. The components cooperate with each other to achieve efficient preparation of nickel-titanium alloy wire.
[0022] The mounting frame 1 serves as the basic support structure for the entire device, stabilizing other components. A pair of fixing rings 10 are horizontally and parallelly arranged on the mounting frame 1. These fixing rings 10 are used to install and position the adjustable polishing component 2. On the front and rear sides of the mounting frame 1, L-shaped support rods 12 are symmetrically distributed. Their vertical parts are firmly welded to the mounting frame 1, while their horizontal parts face upward. At the top of the L-shaped support rods 12, a through-shell 13 is installed. The through-shell 13 is used for the through-positioning of nickel-titanium alloy wire. On both sides of the through-shell 13, threaded cylinders 14 are symmetrically installed. Each threaded cylinder 14 contains a positioning clamp 3.
[0023] The adjustable polishing assembly 2 is one of the core components of this device, mainly composed of an annular body 20 and polishing blocks 24. The annular body 20 is circular, with movable grooves 22 on its top and bottom along the circumferential direction for installing and adjusting the polishing blocks 24. A pair of polishing blocks 24 are symmetrically arranged inside the annular body 20. Screws are vertically fixed at the upper and lower ends of each polishing block 24, with the diameter of the screws matching the width of the movable grooves 22. The two screws pass through the movable grooves 22 at the top and bottom of the annular body 20, respectively, and are securely connected to the annular body 20 by nuts 26. When it is necessary to adjust the spacing between the polishing blocks 24, simply loosen the nuts 26, move the polishing blocks 24 along the movable grooves 22 to the appropriate position, and then tighten the nuts 26 to fix them. Two rings of transmission teeth 23 are arranged around the outside of the annular body 20, located on both sides of the movable grooves 22, for transmitting power.
[0024] On one side of one of the L-shaped support rods 12, a triangular support frame 15 is installed. The triangular support frame 15 is fixed to the L-shaped support rod 12 by welding. A motor 27 is installed on the triangular support frame 15. A gear 28 is fixedly connected to the transmission end of the motor 27. The gear 28 meshes with the two rings of transmission teeth 23 on the outer side of the ring body 20. After the motor 27 is started, its transmission end drives the gear 28 to rotate. Since the gear 28 meshes with the transmission teeth 23, it drives the ring body 20 to rotate, thereby realizing the rotation polishing function of the polishing block 24.
[0025] To ensure the stable rotation of the ring body 20, a sliding groove 11 is provided on the inner wall of the fixed ring 10 along the circumferential direction. At the same time, sliding edges 21 are symmetrically provided on both sides of the ring body 20. The shape and size of the sliding edges 21 match the sliding groove 11. The sliding edges 21 are embedded in the sliding groove 11. When the ring body 20 rotates, the sliding edges 21 slide in the sliding groove 11, ensuring the stability of the rotation of the ring body 20.
[0026] The positioning clamp 3 is mainly used to position and clamp the nickel-titanium alloy wire to prevent it from shifting during processing. The positioning clamp 3 includes a second screw 30, which is installed inside the threaded cylinder 14 by a threaded engagement. The second screw 30 is located at the top of the ring body 20 and is equipped with a bearing 32. The bearing 32 connects the second screw 30 so that the auxiliary clamping block 33 does not rotate when the second screw 30 rotates. The auxiliary clamping block 33 is installed on the outside of the bearing 32. The auxiliary clamping block 33 is used to frame the nickel-titanium alloy wire. A rotating wheel 31 is fixedly installed at the end of the second screw 30 away from the auxiliary clamping block 33. By rotating the rotating wheel 31, the second screw 30 can be easily rotated, thereby adjusting the position of the auxiliary clamping block 33 and realizing the clamping and loosening operation of the nickel-titanium alloy wire.
[0027] In the actual operation of the equipment, firstly, one end of the nickel-titanium alloy wire is passed through the two threading shells 13. After the threading is completed, one end of the nickel-titanium alloy wire is set and firmly fixed to the winding device to prepare for the subsequent winding operation.
[0028] Next, the two rotating wheels 31 located on the same side are turned synchronously. The rotation of the rotating wheels 31 will drive the second screw 30 connected to them to rotate. Under the action of the thread, when the second screw 30 rotates, it will push the auxiliary clamping block 33 to move smoothly inward until the auxiliary clamping block 33 is framed on both sides of the nickel-titanium alloy wire. This action is crucial. It can limit the nickel-titanium alloy wire and effectively prevent the alloy wire from deviating during the subsequent winding process, ensuring the neatness and stability of the winding.
[0029] After the limit is completed, the two grinding blocks 24 need to be moved manually to gradually approach the nickel-titanium alloy wire until both grinding blocks 24 are in full contact with the surface of the nickel-titanium alloy wire and the contact force is uniform. After confirming that the grinding blocks 24 are in good contact with the nickel-titanium alloy wire, the matching nuts 26 are used to tighten and fix the grinding blocks 24 to prevent the grinding blocks 24 from shifting during the grinding operation and affecting the grinding effect.
[0030] Once all preparations are complete, the motor 27 and the winding device can be started simultaneously. After the motor 27 is powered on, its output shaft drives the gear 28 to rotate at high speed. Since the gear 28 meshes with the transmission gear 23, the rotational force of the gear 28 is transmitted, thereby driving the ring body 20 to rotate in a circle. The rotation of the ring body 20 will synchronously drive the two grinding blocks 24 mounted on it to rotate. The high-speed rotating grinding blocks 24 produce a grinding effect on the outer wall of the nickel-titanium alloy wire, thereby achieving the purpose of polishing. At the same time, the winding device starts to work, continuously and stably dragging the nickel-titanium alloy wire forward, so that the nickel-titanium alloy wire passes through the gap between the two grinding blocks 24 at a uniform speed. Under the continuous action of the grinding blocks 24, the polishing operation of the nickel-titanium alloy wire is completed.
