Description

Technical Field

[0001] This utility model is specifically a wire stretching device for beryllium copper microfilaments, belonging to the field of beryllium copper microfilament stretching technology. Background Technology

[0002] Beryllium copper microwires are a type of high-precision copper alloy wire with high elasticity, high conductivity and wear resistance. They are widely used in precision springs, electronic components and other fields. In the processing and production of beryllium copper microwires, the wires need to be stretched to achieve the required diameter. During the stretching process, a wire stretching device is required. Chinese Patent Publication No. CN216369560U discloses a stretching device for alloy wire production, including a mounting base, a wire fixing mechanism, and a stretching mechanism. A wire receiving block is slidably connected to the top of the mounting base, and interconnected wire-passing holes are formed between the left and right sides of the wire receiving block. The wire fixing mechanism includes a mounting frame, a locking slot, and a connecting sliding hole. An electric push rod is fixedly mounted at the bottom of the mounting frame. This stretching device for alloy wire production, by setting up the wire fixing mechanism and the stretching mechanism, provides the advantage of allowing users to easily stretch alloy wire to the desired length, thus facilitating user operation. In existing technologies, during the stretching operation of the line, if the stretching force exceeds the maximum load-bearing capacity of the line itself, the line may suddenly break. This not only affects the progress of the operation, but may also pose a safety risk due to the flying debris, which could injure nearby workers. This reduces the protective effect and poses a safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a wire stretching device for beryllium copper microfilaments to solve the above-mentioned problems. This device addresses the issue that in the prior art, when the wire is stretched beyond its maximum capacity, it is prone to breakage, which could cause injury to nearby workers. This results in low protection and safety hazards.

[0004] This utility model is achieved through the following technical solution: a wire stretching device for beryllium copper microfilaments, including a worktable, support rods fixed at the four corners of the bottom of the worktable, mounting plates symmetrically fixed at the top of the worktable, a bidirectional screw rod connected through bearings between the opposite sides of the two mounting plates, a drive motor fixed on one side of one mounting plate, slide rods symmetrically fixed between the opposite sides of the two mounting plates, sliders symmetrically screwed to the outer side of the bidirectional screw rods, a protective mechanism connected to the top of the worktable, and a fixing mechanism connected to the top of the sliders.

[0006] Preferably, one end of the reset spring is fixed to one side of the mounting bracket, and the reset spring is sleeved on the outside of the insert rod, so that the reset spring can drive the pull plate to reset.

[0007] Preferably, an observation window is provided through one side of the protective cover, and the observation window is connected to explosion-proof glass to facilitate observation of the stretching process. The insertion rod passes through the protective cover to facilitate insertion into the insertion hole.

[0008] Preferably, the slider slides on the outside of the slide rod to limit the slider, so that the slider can only move linearly on the outside of the slide rod. The output shaft end of the drive motor is fixedly connected to one end of the bidirectional screw to facilitate the rotation of the bidirectional screw.

[0009] Preferably, the fixing mechanism includes a connecting block fixed to the top center of the slider, a mounting base fixed to the top of the connecting block, an electric telescopic rod fixed to the center of one side of the inner cavity of the mounting base, a connecting plate fixed to the output shaft end of the electric telescopic rod, a T-shaped block fixed to one side of the connecting plate, clamping blocks symmetrically connected inside the mounting base, and a T-shaped groove opened on one side of the clamping block.

[0010] Preferably, the fixing mechanism further includes a sliding groove formed in the middle of the inner inclined surface of the mounting base, and a sliding strip is fixed in the middle of the inclined side of the clamping block.

[0011] Preferably, the slider slides inside the groove, and the T-block slides inside the T-groove to limit the clamping block and make the clamping block move stably relative to each other.

[0012] This invention provides a wire stretching device for beryllium copper microfilaments, which has the following beneficial effects: 1. This application utilizes a protective mechanism. By pulling a pull plate, the insertion rod moves, stretching the return spring and then deflecting the protective cover to cover the wire. Simultaneously, the insertion rod aligns with the socket. Loosening the pull plate and resetting the return spring allows the insertion rod to be embedded in the socket, thus fixing the protective cover in place. The protective cover effectively shields the device, preventing injury from a broken wire, enhancing the device's protective capabilities, and reducing safety hazards.

[0013] 2. This application, through the setting of a fixing mechanism, places the wire between two clamping blocks, activates the electric telescopic rod, drives the connecting plate to move, thereby moving the two clamping blocks, causing the inclined surface of the mounting base to press against the inclined surface of the clamping blocks. Utilizing the cooperation of the T-block and T-slot, the clamping blocks move closer to each other, clamping and fixing the wire, making fixing faster and more convenient, improving fixing efficiency, and enhancing tensile efficiency.

[0018] Please refer to it again. Figure 2 and Figure 3 The protective mechanism 4 includes a fixing plate 401 fixed to the top edge of the workbench 1. A symmetrical through-hole 402 is provided on one side of the fixing plate 401. A protective cover 403 is hinged to the top of the workbench 1. A mounting bracket 404 is fixed to the bottom of one side of the protective cover 403. A sliding rod 405 is symmetrically slidably passed through one side of the mounting bracket 404. A pull plate 406 is fixed to one end of the rod 405. A return spring 407 is symmetrically fixed to one side of the pull plate 406. One end of the return spring 407 is fixed to one side of the mounting bracket 404, and the return spring 407 is sleeved on the outside of the rod 405. A viewing hole is provided on one side of the protective cover 403. The observation window is equipped with explosion-proof glass, and the insertion rod 405 penetrates the protective cover 403. Through the protective mechanism 4, by pulling the pull plate 406, the insertion rod 405 moves, causing the return spring 407 to stretch. This deflects the protective cover 403, covering the wire and aligning the insertion rod 405 with the socket 402. Loosening the pull plate 406 and resetting the return spring 407 causes the insertion rod 405 to embed into the socket 402, thus fixing the protective cover 403. The protective cover 403 effectively shields the device, preventing injury from a broken wire, enhancing the device's protective capabilities, and reducing safety hazards. Example 2

[0019] Please refer to it again. Figure 4 and Figure 5The fixing mechanism 5 includes a connecting block 501 fixed to the middle of the top of the slider 304. A mounting base 502 is fixed to the top of the connecting block 501. An electric telescopic rod 503 is fixed to the middle of one side of the inner cavity of the mounting base 502. A connecting plate 504 is fixed to the end of the output shaft of the electric telescopic rod 503. A T-shaped block 505 is fixed to one side of the connecting plate 504. Clamping blocks 508 are symmetrically connected inside the mounting base 502. A T-shaped groove 509 is opened on one side of the clamping block 508. The fixing mechanism 5 also includes a sliding groove 506 opened in the middle of the inner inclined surface of the mounting base 502. A sliding groove 506 is fixed to the middle of the inclined surface of the clamping block 508. Strip 507; Slide 507 slides inside slide groove 506, T-block 505 slides inside T-slot 509; With the setting of fixing mechanism 5, by placing the wire between two clamping blocks 508, starting electric telescopic rod 503, driving connecting plate 504 to move, thereby moving the two clamping blocks 508, so that the inclined surface of mounting base 502 presses against the inclined surface of clamping block 508, and by using the cooperation of T-block 505 and T-slot 509, the clamping blocks 508 move closer to each other, clamping and fixing the wire, making fixing faster and more convenient, improving fixing efficiency, and improving stretching efficiency.

[0020] When using this utility model: Working principle: The electrical components are connected to an external power supply and control switch. When stretching the beryllium copper microwire, the beryllium copper microwire is first placed between two clamping blocks 508. The electric telescopic rod 503 is activated, moving the connecting plate 504, which in turn moves the two clamping blocks 508. This causes the inclined surface of the mounting base 502 to press against the inclined surface of the clamping blocks 508. Utilizing the cooperation of the T-block 505 and the T-slot 509, the clamping blocks 508 are brought closer together, clamping and fixing the wire. Then, the pull plate 406 is pulled, moving the insertion rod 405, which stretches the return spring 407. The protective cover 403 is deflected so that it covers the wire, and the insertion rod 405 is aligned with the insertion hole 402. The pull plate 406 is loosened, and the insertion rod 405 is embedded in the insertion hole 402 by the reset spring 407, thus fixing the protective cover 403. The drive motor 302 is started, which drives the bidirectional screw 301 to rotate, so that the sliders 304 move away from each other on the outside of the slider 303, thereby moving the fixing mechanism 5 away from each other, stretching the beryllium copper microwire. The protective cover 403 is used to shield the device and prevent injury when the wire breaks, thus improving the protective performance of the device.
