Description
Technical Field
[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a cutting device for processing nickel-titanium alloys. Background Technology
[0002] Nickel-titanium alloy is a smart material with shape memory effect and superelasticity, which has wide applications in medical, aerospace, and industrial fields. In the medical field, it is used in cardiac stents, orthopedic implants and dental appliances. Its biocompatibility and flexibility are significantly better than traditional materials. In aerospace, automatically deployable satellite antennas and high-temperature resistant components rely on its shape memory properties. In industry, it is used in high-precision components such as automotive shock absorbers and sensors. Its unique properties make it a "deformable metal" in modern technology, continuously driving technological innovation.
[0003] In the processing of nickel-titanium alloy sheets, the feeding process of existing cutting devices has certain defects. Traditional equipment usually uses manual feeding, which is not only inefficient but also makes it difficult to ensure the positioning accuracy of the material, resulting in large deviations in cutting dimensions and affecting product quality. Some semi-automatic feeding devices that have emerged later have introduced simple pushing mechanisms, but they lack effective centering and positioning functions. For nickel-titanium alloy materials with irregular shapes or high elasticity, it is difficult to accurately control their position, which can easily cause cutting deviation. Moreover, fixed-length cutting is heavily dependent on measuring tools, and frequent adjustments to the positioning device are time-consuming and labor-intensive. Therefore, a cutting device for processing nickel-titanium alloys is needed. Utility Model Content

This device can solve the problems that for nickel-titanium alloy materials with irregular shapes or high elasticity, it is difficult to accurately control their position, which can easily cause cutting deviation. Furthermore, fixed-length cutting relies heavily on measuring tools, and frequent adjustments to the positioning device are time-consuming and labor-intensive.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for nickel-titanium alloy processing, comprising a cutting worktable and a feeding mechanism.

[0018] Please see Figure 1-4This utility model provides a technical solution: a cutting device for processing nickel-titanium alloy, including a cutting worktable 1 and a feeding mechanism. The feeding mechanism includes a fixed plate 2, an electric push rod 3, a centering positioning plate 4, a motor 14, a threaded rod 15, and a feeding push plate 16. There are two fixed plates 2, both fixedly connected to the top of the cutting worktable 1. There are multiple electric push rods 3, all fixedly connected to the surface of the fixed plates 2. The number of centering positioning plates 4 is the same as that of the fixed plates 2, and they are all slidably connected to the top of the cutting worktable 1. Each centering positioning plate 4 is fixedly connected to the output end of the electric push rod 3. The motor 14 is fixedly connected to the top of the cutting worktable 1. The threaded rod 15 is rotatably connected to the top of the cutting worktable 1, and the threaded rod 15 is fixedly connected to the output end of the motor 14. The feeding push plate 16 is threadedly sleeved on the outer surface of the threaded rod 15, and the feeding push plate 16 is slidably connected to the top of the cutting worktable 1.
[0019] Furthermore, the feeding mechanism also includes a mounting plate 17, a hydraulic cylinder B18, and a length limiting plate 19. The mounting plate 17 is fixedly connected to the top of the cutting worktable 1, the hydraulic cylinder B18 is fixedly connected to the surface of the mounting plate 17, and the length limiting plate 19 is slidably connected to the top of the cutting worktable 1. The length limiting plate 19 is fixedly connected to the output end of the hydraulic cylinder B18. A device bracket 5 is fixedly connected to the top of the cutting worktable 1, and a hydraulic cylinder A6 is fixedly connected to the bottom of the device bracket 5. A lifting blade is fixedly connected to the output end of the hydraulic cylinder A6. The bottom of the lifting blade holder 7 is fixedly connected to a cutting blade 8. A slide rod 11 is slidably connected to the surface of the lifting blade holder 7. A positioning frame 9 is fixedly connected to the bottom of the slide rod 11. A return spring 12 is fixedly connected to the opposite surfaces of the lifting blade holder 7 and the positioning frame 9. A slot 10 is opened on the surface of the positioning frame 9. A blade groove 13 is opened on the top of the cutting worktable 1. A device base 20 is fixedly connected to the bottom of the cutting worktable 1. A collection box 21 is movably connected inside the device base 20. The bottom of the blade groove 13 is connected to the inside of the collection box 21.
[0020] Further, the nickel-titanium alloy material to be cut is placed on the cutting worktable 1, between two centering positioning plates 4. The electric push rod 3 is activated, pushing the centering positioning plates 4 to slide on the top of the worktable 1, aligning the nickel-titanium alloy material from both sides to ensure accurate cutting position. Then, the motor 14 drives the threaded rod 15 to rotate, causing the threaded feeding push plate 16 to slide along the top of the worktable 1, pushing the material to the cutting area. At this time, the hydraulic cylinder B18 pushes the fixed-length limiting plate 19 to move to the preset position, limiting the material's forward distance and realizing the fixed-length cutting function. During the cutting process, the hydraulic cylinder A6 drives the lifting blade seat 7 to descend, so that the cutting blade 8 contacts and cuts the material. The positioning frame 9 contacts the material surface before the cutting blade 8 to position and press the material, preventing the material from shifting during cutting. The return spring 12 helps the positioning frame 9 to return to its original position after cutting. The waste generated by cutting falls into the collection box 21 in the device base 20 through the blade groove 13 for centralized processing.
[0021] Furthermore, the combination of electric push rod and centering positioning plate can automatically center and position nickel-titanium alloy materials, improving cutting accuracy and consistency. The threaded transmission mechanism composed of feeding push plate and threaded rod can achieve smooth and precise feeding action, avoiding material shaking or jamming during the pushing process. The setting of fixed length limit plate and hydraulic cylinder B allows the cutting length to be precisely adjusted by hydraulic control, eliminating the need for frequent manual measurement and adjustment. It is suitable for cutting nickel-titanium alloy materials of different specifications, improving production efficiency and automation. The design of positioning frame and return spring plays a role in pre-compressing and positioning the material during cutting. The slotted design avoids the cutting blade, effectively preventing material slippage and deformation, and ensuring the flatness of the cut surface.
