Description

Technical Field

[0001] This utility model relates to the field of cold drawing machine technology, specifically to an adjustment component for a shape memory alloy cold drawing machine. Background Technology

[0002] Nickel-titanium shape memory alloy wire is an alloy material with a unique shape memory effect and superelasticity. It is mainly composed of nickel and titanium. This alloy wire can automatically recover its original shape at a specific temperature and exhibits an elastic limit far exceeding that of ordinary materials. These properties have led to the widespread application of nickel-titanium shape memory alloy wire in many fields, especially in the field of medical devices, such as cardiac stents and intravascular catheters.

[0003] In the production of nickel-titanium shape memory alloy wire, the cold drawing machine can produce alloy wire of the required specifications according to demand. The specifications of the mold on the cold drawing machine can produce the corresponding alloy wire. After the alloy wire is produced, it is usually wound onto a drum by a rotating shaft driven by a motor, so that it can be effectively collected and stored for subsequent processing and use.

[0004] However, since the alloy wire is kept straight during production and rotated by a motor, the alloy wire may be repeatedly wound in the same place on the spool. This can cause friction between the alloy wires, resulting in damage to the surface of the alloy wire and affecting its quality. Furthermore, uneven winding of the alloy wire on the spool can also cause difficulties in subsequent collection, transportation, and storage. Utility Model Content

[0005] The purpose of this invention is to provide an adjustment component for a shape memory alloy cold drawing machine, so as to solve the problem that alloy wires may be damaged during winding as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustment component for a shape memory alloy cold drawing machine includes: a main body with a mounting base, a rotating shaft on the mounting base, and a drum on the rotating shaft; an adjustment mechanism mounted on the mounting base, comprising a lead screw mounted on the mounting base, a roller mounted on the lead screw, a spring mounted on the roller, and an arc-shaped plate mounted on the spring; the adjustment mechanism is used for adjusting the position of the wire; and a replacement mechanism mounted on the mounting base, comprising an elastic element mounted on the mounting base, a movable plate mounted on the elastic element, and a rotating cylinder mounted on the movable plate; the replacement mechanism is used for replacing the drum.

[0008] Preferably, the adjustment mechanism further includes a connecting plate disposed on one side of the movable plate, a servo motor disposed on one side of the connecting plate, and a lead screw disposed at the output end of the servo motor.

[0009] Preferably, a movable block is provided on the outer side of the lead screw, and a slider is provided on the side of the movable block near the connecting plate. A groove is provided on the connecting plate corresponding to the slider, and the slider is movably disposed in the groove.

[0010] Preferably, the roller is rotatably arranged inside the moving block, and two sets of springs are symmetrically arranged inside the moving block, with a pull plate at one end of each spring.

[0011] Preferably, an arc-shaped plate is fixedly connected to one side of the pull plate, and the arc-shaped plate is in contact with the roller.

[0012] Preferably, the replacement mechanism also includes a fixing plate fixedly installed on one side of the mounting base, and the rotating shaft is mounted on the fixing plate.

[0013] Preferably, a T-shaped block is fixedly connected to the side of the movable plate near the mounting base, and a T-shaped groove is provided on the mounting base corresponding to the T-shaped block, with the T-shaped block movably disposed in the T-shaped groove.

[0014] Preferably, a slide rod is fixedly connected inside the T-groove, a T-block is movably mounted on the slide rod, an elastic element is provided on one side of the T-block, one side of the elastic element is fixedly installed inside the T-groove, and the elastic element is located on the outside of the slide rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] After the alloy wire is produced, it is usually wound onto a spool. To prevent the alloy wire from being wound repeatedly on the spool, the speed of the servo motor is controlled, which drives the moving block through the lead screw. This moves the alloy wire, effectively preventing it from being wound repeatedly on the spool and making the alloy wire wound more evenly. The elastic force of the spring can drive the arc plate to firmly fix the alloy wire in the middle of the roller, effectively preventing the alloy wire from getting stuck.

[0017] The elastic force of the elastic element can drive the moving plate to clamp the drum, making it easier for workers to change the drum and place drums of different specifications. This makes the device more adaptable and can produce alloy wire coils of different specifications. Attached Figure Description

Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 - Figure 6 As shown, this application provides an adjustment component for a shape memory alloy cold drawing machine, including: a device body 1, a mounting base 2 on the device body 1, a rotating shaft 6 on the mounting base 2, a drum 5 on the rotating shaft 6, and an adjustment mechanism on the mounting base 2. The adjustment mechanism includes a lead screw 10 on the mounting base 2, a roller 17 on the lead screw 10, a spring 20 on the roller 17, and an arc plate 18 on the spring 20. The adjustment mechanism is used for adjusting the position of the wire.

[0028] Specifically, such as Figure 2As shown, the adjustment mechanism also includes a connecting plate 8 disposed on one side of the movable plate 4. A servo motor 7 is disposed on one side of the connecting plate 8, and a lead screw 10 is disposed at the output end of the servo motor 7. The rotation of the servo motor 7 can stably drive the lead screw 10 to rotate.

[0029] Specifically, such as Figure 3 As shown, a movable block 9 is provided on the outer side of the lead screw 10. A slider 21 is provided on the side of the movable block 9 near the connecting plate 8. A groove 11 is provided on the connecting plate 8 corresponding to the slider 21. The slider 21 is movably disposed in the groove 11. Through the cooperation between the slider 21 and the groove 11, the movement direction of the movable block 9 can be limited.

[0030] Specifically, such as Figure 6 As shown, the roller 17 is rotatably mounted inside the moving block 9. Two sets of springs 20 are symmetrically arranged inside the moving block 9. One end of the spring 20 is provided with a pull plate 19. The pull plate 19 facilitates the movement of the spring 20 by driving the pull plate 19.

[0031] Specifically, such as Figure 6 As shown, an arc-shaped plate 18 is fixedly connected to one side of the pull plate 19. The arc-shaped plate 18 contacts the roller 17. By setting the arc-shaped plate 18, the position of the alloy wire can be fixed in the middle of the roller 17.

[0032] The mounting base 2 is provided with a replacement mechanism, which includes an elastic element 16 provided on the mounting base 2, a movable plate 4 provided on the elastic element 16, and a rotating cylinder 12 provided on the movable plate 4. The replacement mechanism is used for replacing the drum 5.

[0033] Specifically, such as Figure 5 As shown, the replacement mechanism also includes a fixed plate 3 fixedly installed on one side of the mounting base 2, and a rotating shaft 6 installed on the fixed plate 3. By rotating the rotating shaft 6, the drum 5 can be driven to rotate, thereby driving the drum 5 to wind the alloy wire into a ball.

[0034] Specifically, such as Figure 3 As shown, a T-shaped block 14 is fixedly connected to the side of the movable plate 4 near the mounting base 2. A T-shaped groove 13 is provided on the mounting base 2 corresponding to the T-shaped block 14. The T-shaped block 14 is movably disposed in the T-shaped groove 13. Through the cooperation between the T-shaped groove 13 and the T-shaped block 14, the moving direction of the movable plate 4 can be limited.

[0035] Specifically, such as Figure 4As shown, a slide rod 15 is fixedly connected inside the T-shaped groove 13, and a T-shaped block 14 is movably mounted on the slide rod 15. An elastic element 16 is provided on one side of the T-shaped block 14, and one side of the elastic element 16 is fixedly installed inside the T-shaped groove 13. The elastic element 16 is located on the outside of the slide rod 15. The setting of the elastic element 16 facilitates the movement plate 4 and the fixed plate 3 to cooperate in limiting the movement of the drum 5 of different specifications.

[0036] In this embodiment: the rotation of the servo motor 7 drives the lead screw 10 to rotate, which in turn drives the moving block 9 to move stably. This allows the alloy wire to move as needed, thus enabling the alloy wire to be wound at different positions on the drum 5. This allows for adjustment of the winding position of the alloy wire, preventing it from being wound repeatedly in the same place. The elastic force of the elastic element 16 drives the moving plate 4 to move towards the fixed plate 3, allowing the rotating cylinder 12 to cooperate with the rotating shaft 6 to fix drums 5 of different lengths. This enables the device to produce alloy wire coils of different specifications, making the device more adaptable.

[0037] Specifically, the solution is as follows: When the produced alloy wire needs to be wound onto the drum 5, the alloy wire is wound once onto the roller 17 and then onto the drum 5. The rotation of the rotating shaft 6 drives the drum 5 to rotate, thus winding the alloy wire onto the drum 5. To prevent the alloy wire from being repeatedly wound in the same place on the drum 5, the rotation of the servo motor 7 is controlled, which drives the lead screw 10 to rotate, thereby moving the moving block 9 and thus moving the alloy wire. This ensures that the alloy wire is wound onto the drum 5. The alloy wire is wound evenly, and the roller 17 makes the winding smoother. The spring 20, in conjunction with the arc plate 18, fixes the position of the alloy wire in the middle of the roller 17, preventing the alloy wire from getting stuck. The elastic force of the elastic element 16 keeps the moving plate 4 moving towards the fixed plate 3. The cooperation between the moving plate 4 and the fixed plate 3 can fix the spools 5 of different lengths. The slide bar 15 prevents the elastic element 16 from bending when compressed.
