Description

Technical Field

[0001] The present invention specifically relates to a breaking device for alloy wires and belongs to the technical field of alloy wire production. Background Art

[0002] As a high-performance material, alloy wires are widely used in fields such as aerospace, electronic information, medical devices, and precision instruments due to their characteristics such as corrosion resistance, high electrical conductivity, and fatigue resistance. For example, in the electronics industry, alloy wires are used to manufacture precision resistors and inductance components; in the medical field, nickel-titanium alloy wires are the core materials for vascular stents and orthodontic wires. With the development of high-end manufacturing, the market has put forward higher requirements for the processing accuracy of alloy wires (such as length consistency and flatness of fracture surfaces), especially during batch breaking operations, and the limitations of traditional equipment have become increasingly prominent.

[0003] For example, the Chinese invention patent application document with the application number 202411884204.6 discloses a breaking device for alloy wires. During the process of limiting and fixing one end of the alloy wire, through a limiting component, different-sized alloy wires can be quickly limited and fixed. And during the breaking operation of the alloy wire, the stability of the alloy wire is monitored by a distance monitoring sensor, so that the phenomenon of unstable limitation of the alloy wire can be detected in time, and the offset generated by the alloy wire can be monitored.

[0004] In the above document, the alloy wire is wound by a winding column and the position of the alloy wire is limited through a first connection cavity and a second connection cavity. However, the first connection cavity and the second connection cavity need to rotate, which is of little help for the breaking operation. And the operation method of using auxiliary rollers for limiting and clamping has a relatively simple function. During the breaking operation, neither side of the cut of the alloy wire is fixed. Therefore, this will cause the end of the alloy wire to move, resulting in uneven cuts, affecting the quality of the alloy wire, increasing the damaged part of the alloy wire, and causing resource waste problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a breaking device for alloy wires to solve the problem that the end part is uneven when cutting alloy wires in the prior art.

[0025] The alloy wire enters from one side of the static seat body 1, and the part to be broken is located between the upper tool body 501 and the lower tool body 502. The support block 303 is used to support the alloy wire, so that the upper tool body 501 can easily fix the alloy wire. The upper tool body 501 can be suspended above the alloy wire.

[0029] A positioning mechanism 9 is installed on one side of the upper tool body 501. The positioning mechanism 9 includes a horizontal plate 901 fixed to the side wall of the upper tool body 501. The bottom of the horizontal plate 901 is fixedly connected to a lower pressing plate 903 through a buffer spring 902.

[0030] The rear transportation component 6 includes a rear bearing plate 601. A receiving groove is provided on the upper surface of the rear bearing plate 601. A transportation roller 602 is provided in the receiving groove. Both ends of the transportation roller 602 are rotatably clamped on the inner wall of the floating side plate 201. A lifting seat 603 is fixed to the bottom of the rear bearing plate 601. The lifting seat 603 is used to drive the floating seat body 2 to lift, thereby realizing the pressing and breaking operation. The lifting seat 603 needs to be connected to an external hydraulic lifting device.

[0031] The downward pressing component 4 includes a downward pressing roller 401. Limiting patterns are provided on the outer walls of both the downward pressing roller 401 and the bearing roller 103. The limiting patterns are used to fix the position of the alloy wire. The downward pressing roller 401 is rotatably installed at the bottom of the downward pressing frame body 402. A control device 404 for controlling the up and down movement of the downward pressing frame body 402 is installed on the first bearing plate 102. A power motor 403 for driving the downward pressing roller 401 to rotate is fixed to the downward pressing frame body 402. A pair of ear plates are provided at the bottom of the downward pressing frame body 402. The downward pressing roller 401 is rotatably clamped between the ear plates, and one end extends outside the ear plates and is power-connected to the output shaft of the power motor 403 through a transmission belt.

[0032] The control device 404 includes a lifting telescopic rod 441 fixed to the first bearing plate 102. A side extension plate 442 is fixed to the top of the lifting telescopic rod 441. A positioning column 443 is slidably clamped on the side extension plate 442. The bottom end of the positioning column 443 is fixed to the upper part of the downward pressing frame body 402. A downward pressing spring 444 is fixedly connected between the bottom of the downward pressing frame body 402 and the side extension plate 442.

[0033] During use, the alloy wire enters the device from one side of the static seat body 1, passes through the round roller 302 on the front bearing plate 301 of the front transportation component 3. The round roller 302 rotates to guide the alloy wire to move forward smoothly to the accommodation notch position. At this time, the downward pressing component 4 is started. The lifting telescopic rod 441 of the control device 404 drives the side extension plate 442 to rise. The positioning column 443 ensures the smooth movement of the downward pressing frame body 402. The downward pressing spring 444 provides a buffer force to make the downward pressing roller 401 move downward, and cooperates with the bearing roller 103 to fix the position of the alloy wire through the limiting patterns. The power motor 403 drives the downward pressing roller 401 to rotate to drive the alloy wire to be transported forward.

[0034] When the part of the alloy wire to be broken reaches between the upper tool body 501 and the lower tool body 502, the supporting block 303 supports the alloy wire. The tool control telescopic rod 504 drives the upper tool body 501 to descend. At the same time, the horizontal plate 901 of the positioning mechanism 9 descends with the upper tool body 501. The lower pressing plate 903 contacts and presses the alloy wire in advance under the action of the buffer spring 902 for positioning, avoiding the shaking of the alloy wire during breaking. At the same time, the conveying roller 602 of the rear conveying assembly 6 can carry the alloy wire. The lifting seat 603 is connected to an external hydraulic lifting device to drive the floating seat body 2 to rise, and the lower tool body 502 rises accordingly. The limiting shell 701, limiting slide bar 702, end block 703, and slider 704 of the linkage mechanism 7 ensure the stable movement track of the floating seat body 2. The tightening spring 803 of the reset mechanism 8 tightens the moving rod 801 to make the floating seat body 2 close to the static seat body 1. The side walls of the upper tool body 501 and the lower tool body 502 approach and are misaligned and pressed together to break the alloy wire. After breaking, the lifting seat 603 drives the floating seat body 2 to descend and reset. The tool control telescopic rod 504 drives the upper tool body 501 to rise, and the lower pressing plate 903 resets with the upper tool body 501. In this way, continuous alloy wire breaking operations are carried out in a cycle. After cutting, the alloy wire is preferably extracted using an external device for subsequent packaging.

[0035] Embodiment 2: On the basis of Embodiment 1, the lower tool body 502 is separated from the floating side plate 201, and a hydraulic driving device is fixed at the bottom of the lower tool body 502. During cutting, the lower pressing plate 903 on the positioning mechanism 9 presses on the alloy wire, and a cylinder is used to push the floating side plate 201 to one side. At this time, the alloy wire is tightened, and then subsequent breaking is carried out. During breaking, the floating side plate 201 and the lower tool body 502 rise together, and thus the alloy wire is broken.
