Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire EDM processing technology, specifically to a floating guide wire structure that reduces secondary cutting errors. Background Technology
[0002] During the continuous drawing or rolling process of metal wire, due to factors such as fluctuations in incoming material dimensions, die wear, temperature changes, and equipment vibration, the wire often experiences a "secondary cutting" phenomenon. That is, after the wire has been cut to a fixed length once, it may come into unexpected contact with the cutting tool again due to subsequent fluctuations in traction tension or speed mismatch, resulting in quality defects such as oblique cuts, burrs, length deviations, and surface scratches.
[0003] Meanwhile, secondary cutting errors not only directly increase the scrap rate but also force subsequent processes to invest additional manpower and equipment, significantly reducing production efficiency and increasing costs. A search revealed that Chinese patent CN216325679U discloses a wire cutting guide device. During use, the wire needs to be inserted into the through hole so that the entire through hole can be positioned by the device. The size of the opening between the two devices can be adjusted by the cooperation of the top rod and the first sliding plate. Then, the user can adjust the distance between the first and second sliding plates according to the thickness of the wire, thus adapting to different specifications. Furthermore, since there are rotating drums in both the second and first sliding plates, the friction can be effectively reduced when the wire passes through, facilitating the wire's passage and preventing cutting misalignment. It is also suitable for wires of different specifications.
[0004] Although the above-mentioned utility model can reduce the resistance and friction of the wire passage to a certain extent through the adjustable opening of the first and second slide plates and the design of the rotating drum, the position of the rotating drum itself is fixed and has no buffering ability for the radial jump of the wire caused by the instantaneous fluctuation of tension. This can lead to the wire still being "secondarily cut" at the moment of cutting, resulting in oblique cuts or burrs on the end face. Based on this, a floating guide wire structure to reduce the error of secondary cutting is proposed to solve the above problems. Utility Model Content
[0005] Based on the above description, this utility model provides a floating guide wire structure to reduce secondary cutting errors, in order to solve the problem that the position of the rotating drum itself is fixed and has no buffering ability for the radial runout caused by the instantaneous fluctuation of tension of the wire, which may still cause "secondary cutting" phenomenon at the moment of cutting, resulting in oblique cut or burrs on the end face.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a floating guide wire structure for reducing secondary cutting errors, including a main frame;
[0007] One side of the main frame is provided with a thread hole for passing the wire through. Two movable plates are provided on the opposite side of the front and rear side walls of the inner cavity of the main frame. Each of the two movable plates is provided with a floating guide mechanism for guiding the wire during cutting. The upper and lower sides of the movable plates are provided with fixing mechanisms for fixing the floating guide mechanism to the movable plates.
[0008] The floating guide mechanism includes mounting slots opened on opposite sides of the two movable plates. The inner cavity of the mounting slot is provided with multiple U-shaped fixing seats, and the inner top wall and inner bottom wall of the U-shaped fixing seats are provided with buffers.
[0009] The above technical solution utilizes multiple rollers to synchronously extend and retract when the wire experiences radial runout due to sudden tension changes. This efficiently absorbs and quickly stabilizes the instantaneous displacement of the wire through elastic damping, avoiding rigid impacts and absorbing the radial runout of the wire in real time while maintaining low-friction guidance, thereby significantly reducing secondary cutting errors.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the cross-sectional shape of the main frame is U-shaped, and the threading hole is located at the center on the side opposite to the opening of the main frame.
[0012] The above technical solution allows the wire to be cut to be passed through the wire through the wire, and then guided by the rollers on both sides.
[0013] Furthermore, screws are rotatably installed in the middle of the opposite sides of the two movable plates. The opposite sides of the two screws pass through the main frame and extend to the front and rear sides of the main frame, respectively. The screws are threadedly connected to the main frame.
[0014] Through the above technical solution, the threaded connection between the two screws and the main frame allows the two screws to move relative to each other or in opposite directions, thereby changing the distance between the two movable plates and thus adapting to the cutting of wires of different diameters.
[0015] Furthermore, the U-shaped fixing seat is fixed between the top wall and the bottom wall of the mounting groove on opposite sides, and multiple U-shaped fixing seats are evenly distributed in the inner cavity of the mounting groove.
[0016] The above technical solution allows for the installation and removal of the roller, facilitating its replacement after damage.
[0017] Furthermore, the buffer includes an elastic damper fixed to the opposite side of the top and bottom walls of the U-shaped fixed seat. Movable plates are fixed to the opposite sides of the upper and lower elastic dampers. A shaft is rotatably connected to the opposite side of the upper and lower movable plates via a bearing. A roller is fixed to the outer side of the shaft.
[0018] Through the above technical solution, the buffer component utilizes the compression-rebound characteristics of elastic damping to convert instantaneous displacement into controllable deformation energy and simultaneously dissipate vibration energy, avoiding rigid impact. At the same time, the wire and the roller maintain rolling contact, significantly reducing the coefficient of friction and protecting the surface of the wire.
[0019] Furthermore, the outer surface of the roller is covered with polyurethane material, and one side of both the front and rear rollers extends into the mounting groove.
[0020] The above technical solution provides a polyurethane material on the outer surface of the roller to provide adequate elasticity to absorb the lateral impact of the guide wire.
[0021] Furthermore, the fixing mechanism includes threaded holes on the upper and lower sides of the movable plate, and threaded grooves are provided on both the upper and lower sides of the U-shaped fixing seat. A T-shaped rod is threadedly connected to the inner cavity of the threaded hole.
[0022] The above technical solution uses double-sided threaded locking to form a symmetrical clamping, thereby fixing the U-shaped fixed seat and the movable plate.
[0023] Furthermore, the threaded holes on the upper and lower sides correspond one-to-one with the threaded grooves, and the T-shaped rod passes through the threaded hole and extends into the inner cavity of the threaded groove.
[0024] With the above technical solution, one end of the T-shaped rod is embedded in the threaded groove and threaded hole, which facilitates quick connection and fixation between the U-shaped fixing seat and the movable plate, ensuring the stability of the roller fixation.
[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0026] When the wire experiences radial runout due to sudden tension changes, the elastic supports of each roller synchronously extend and retract, efficiently absorbing and quickly stabilizing the instantaneous displacement of the wire with elastic damping, avoiding rigid impact, absorbing the radial runout of the wire in real time, and maintaining low-friction guidance, thereby significantly reducing secondary cutting errors. Threaded holes and threaded grooves are respectively opened on the upper and lower sides of the movable plate and the U-shaped fixed seat, and their interaction with the T-shaped rod can fix the U-shaped fixed seat and the movable plate.

[0036] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0038] Example: Reference Figure 1 and Figure 2 A floating guide wire structure for reducing secondary cutting errors includes a main frame 1; a wire-passing hole 2 is provided on one side of the main frame 1 for passing the wire through; two movable plates 3 are provided on opposite sides of the front and rear side walls of the inner cavity of the main frame 1; a floating guide mechanism 4 is provided on the opposite side of the two movable plates 3 for guiding the wire during cutting; and a fixing mechanism 5 is provided on the upper and lower sides of the movable plates 3 for fixing the floating guide mechanism 4 to the movable plates 3.
[0039] The main frame 1 has a U-shaped cross-section, and the wire hole 2 is located at the center on the opposite side of the opening of the main frame 1.
[0040] In this embodiment, screws 6 are rotatably installed in the middle of the opposite sides of the two movable plates 3. The opposite sides of the two screws 6 pass through the main frame 1 and extend to the front and rear sides of the main frame 1. The screws 6 are threadedly connected to the main frame 1. The screws 6 can be rotated to make them displaced, thereby driving the two movable plates 3 to move relative to each other or in opposite directions. This can change the distance between the two rollers 47 to adapt to the cutting guide of wires of different sizes.
[0041] When in use, pass one end of the wire through the wire hole 2, and then rotate the screw 6. Since the screw 6 is threadedly connected to the main frame 1, the screw 6 will move. The movement of the screw 6 causes the movable plate 3 to move, so that the two movable plates 3 move relative to or away from each other on the main frame 1. The distance between the two movable plates 3 can be adjusted to accommodate wires of different diameters.
[0042] refer to Figure 3 The floating guide mechanism 4 includes a mounting groove 41 opened on one side of the two movable plates 3. The inner cavity of the mounting groove 41 is provided with a plurality of U-shaped fixing seats 42. The inner top wall and the inner bottom wall of the U-shaped fixing seats 42 are provided with buffers 43 on the opposite side.
[0043] Among them, the U-shaped fixing seat 42 is fixed between the opposite sides of the inner top wall and the inner bottom wall of the mounting groove 41, and multiple U-shaped fixing seats 42 are evenly distributed in the inner cavity of the mounting groove 41.
[0044] In this embodiment, the buffer 43 includes an elastic damper 44 fixed to the opposite side of the inner top wall and inner bottom wall of the U-shaped fixed seat 42. A movable plate 45 is fixed to the opposite side of the upper and lower elastic dampers 44. A shaft 46 is rotatably connected to the opposite side of the upper and lower movable plates 45 through a bearing. A roller 47 is fixed to the outer side of the shaft 46. During cutting, the wire passes between the two rollers 47. If the tension fluctuates instantaneously and causes the wire to bounce radially, the elastic damper 44 immediately compresses or rebounds, and the movable plate 45 floats synchronously, driving the roller 47 to roll and displace under the support of the bearing. This converts the bounce energy into elastic potential energy and dissipates it quickly. At the same time, the roller 47 continuously constrains the wire, keeping its center line aligned with the cutting edge, thereby effectively suppressing secondary cutting errors and ensuring a smooth cut without burrs.
[0045] The outer surface of the roller 47 is covered with polyurethane material. The viscoelasticity of polyurethane can absorb high-frequency vibration energy and reduce the amplitude transmitted to the wire path. One side of the front and rear rollers 47 extends into the mounting groove 41.
[0046] refer to Figure 4 and Figure 5The fixing mechanism 5 includes threaded holes 51 on the upper and lower sides of the movable plate 3, and threaded grooves 52 on both the upper and lower sides of the U-shaped fixing seat 42. A T-shaped rod 53 is threadedly connected to the inner cavity of the threaded hole 51.
[0047] Among them, the threaded holes 51 on the upper and lower sides correspond one-to-one with the threaded grooves 52, and the T-shaped rod 53 passes through the threaded holes 51 and extends into the inner cavity of the threaded grooves 52.
[0048] In use, the U-shaped fixing seat 42 is placed one by one with the threaded holes 51 on the upper and lower sides of the movable plate 3, and then the T-shaped rod 53 is screwed into the threaded hole 51 so that its other end enters the inner cavity of the threaded groove 52, thereby fixing the U-shaped fixing seat 42 and the movable plate 3 through the T-shaped rod 53.
[0049] It should be noted that threaded holes 51 and threaded grooves 52 are respectively opened on the upper and lower sides of the movable plate 3 and the U-shaped fixing seat 42, and the mutual cooperation between them and the T-shaped rod 53 can fix the U-shaped fixing seat 42 and the movable plate 3.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
