Description

Technical Field

[0001] This utility model relates to the field of shaped wire drawing machines, and in particular to a guiding mechanism for shaped wire drawing machines. Background Technology

[0002] A profiled wire drawing machine is a specialized device for processing metal wires with irregular cross-sections (such as square, rectangular, hexagonal, triangular, and other non-circular cross-sections). Compared to conventional round wire drawing machines, profiled wire drawing machines have higher design requirements, involving specialized guiding, stretching, and die systems.

[0003] Existing technologies, such as the utility model patent with publication number CN213316902U, disclose a novel shaped wire drawing machine device. This patent employs a machine body and a limiter. The machine body has a drawing mechanism for drawing shaped wires. Support walls are fixedly connected to both ends of the top of the machine body, and a take-up roller is rotatably connected between the two support walls. The limiter is located between the drawing mechanism and the take-up roller. The limiter includes two limit plates, a transmission roller, and a pressure roller. It can limit the size of the channel between the pressure roller and the transmission roller, preventing shaped wires with offset cross-sections from passing through the channel. The pressure roller then presses and straightens the entering shaped wire, shifting the cross-section of the shaped wire with offset cross-sections to one direction. This avoids wear on the wire cross-section caused by the sharp edges of the shaped wire contacting the cross-section during winding, thus improving the quality of the wire.

[0004] The inventors discovered in daily use that the irregular shape of the shaped filaments in existing technologies easily leads to deviation during the drawing process. Improperly designed guiding systems can cause the shaped filaments to sway, deviate, or jam when passing through the guiding device, resulting in instability in the drawing process and affecting product precision and quality. Furthermore, because certain edges and corners of the shaped filaments are more susceptible to friction and tension than other parts, the wear on the guiding system and mold is often uneven, leading to equipment malfunctions or increased operational difficulty with prolonged use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies.

[0006] To solve the above technical problems, this utility model provides a guiding mechanism for a wire drawing machine for irregularly shaped wires, comprising: four supports and an adjustment structure. A platform is fixedly connected to the upper end of each support. Two protective shells are fixedly connected to the upper surface of the platform. Two servo motors are arranged below the platform. A wire drawing device is installed at the output end of each servo motor. The servo motors are connected to the platform via the adjustment structure. An auxiliary structure is provided on the upper surface of the platform. The auxiliary structure includes four sliding grooves, which are arranged in pairs. Both groups of sliding grooves are located on the platform. A slider is slidably connected to the inner wall of each sliding groove. A connecting plate is fixedly connected to the side of the slider away from the wire drawing device. A screw is threadedly connected to the inner wall of the connecting plate, and the screw abuts against the platform. A connecting frame is fixedly connected to the upper surface of the slider. Several rotating shafts are fixedly connected inside the connecting frame. Rollers are rotatably connected to the arc surface of each rotating shaft. A spring is arranged inside each sliding groove, and both ends of the spring are fixedly connected to the slider and the sliding groove, respectively.

[0007] The effect achieved by the above components is as follows: when it is necessary to guide the material, the material is pulled to move, and then the material comes into contact with the roller. The material drives the roller to move, the roller drives the rotating shaft to move, the rotating shaft drives the connecting frame to move, the connecting frame drives the slider to move, the slider drives the connecting plate and the screw to move, the slider drives the spring to stretch, and then the spring's rebound force drives the roller to abut against the roller. When guiding materials of the same type, the screw is tightened to fix them.

[0008] Preferably, a limiting rod is fixedly connected to the inner wall of the groove, the limiting rod is slidably connected to the slider, and the spring is sleeved on the arc surface of the limiting rod.

[0009] The effect achieved by the above components is that the limiting rod can limit the spring, prevent the spring from deforming during use, and improve the service life of the spring.

[0010] Preferably, the roller has a plurality of slots on its arc surface, and the plurality of slots are evenly distributed on the roller.

[0011] The effect achieved by the above components is that the groove can increase the friction between the roller and the material, and prevent sliding wear between the material and the roller.

[0012] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one end of the screw near the table surface.

[0013] The effect achieved by the above components is that the protective pad can increase the friction between the screw and the table surface, preventing the screw from sliding when it is fixed to the table surface.

[0014] Preferably, the lower surface of the tabletop is provided with an adjustment structure, the adjustment structure including two connecting plates, both of which are fixedly connected to the tabletop. The lower end of the connecting plate is fixedly connected to a slide rail, the inner wall of the slide rail is slidably connected to a moving block, the upper surface of the moving block is fixedly connected to a fixed frame, the fixed frame is fixedly connected to a servo motor, the inner wall of the slide rail is threaded with a lead screw, the arc surfaces at both ends of the lead screw are provided with opposite threads, the lead screw is threadedly connected to the moving block, and one end of the lead screw is fixedly connected to a turntable.

[0015] The effect achieved by the above components is as follows: when it is necessary to adjust the spacing between the wire drawing devices, the turntable is rotated to move, the turntable drives the lead screw to rotate, the lead screw drives the moving block to move, the moving block slides on the inner wall of the slide rail, the moving block drives the fixed frame to move, the fixed frame drives the servo motor to move, and the servo motor drives the wire drawing device to move.

[0016] Preferably, the fixed frame has a circular cross-section and is made of plastic.

[0017] The effect achieved by the above components is that the plastic material is relatively inexpensive, which can greatly reduce the manufacturing cost of the fixing frame.

[0018] Preferably, a plurality of handles are fixedly connected to the arc surface of the turntable, and the plurality of handles are evenly distributed on the arc surface of the turntable.

[0019] The effect achieved by the above components is that the lever can be directly rotated when rotating the turntable, and the lever drives the turntable to rotate, making it more convenient to rotate the turntable.

[0020] Compared with related technologies, the wire drawing machine guide mechanism for irregularly shaped wires provided by this utility model has the following beneficial effects:

[0021] By incorporating auxiliary structures, existing technologies address the issue that irregularly shaped filaments are prone to deviation during the drawing process. Improperly designed guide systems can cause swaying, deflection, or jamming of the filaments as they pass through the guide device, leading to instability in the drawing process and affecting product precision and quality. Furthermore, because certain edges and corners of the filaments are more susceptible to friction and tension than other parts, the wear on the guide system and mold is often uneven, potentially causing equipment malfunctions or increased operational difficulty over time. This new device effectively guides filaments and allows for quick adjustment of the guide device spacing based on different filament types, improving both processing efficiency and quality.

[0022] By setting an adjustment structure, the wire drawing device can be quickly adjusted according to the type of shaped wire, avoiding the difficulty of quick adjustment when drawing different shaped wires. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 4 The present invention provides a wire drawing machine guide mechanism for irregularly shaped wires, comprising: four supports 1 and an adjustment structure 7. A table 2 is fixedly connected to the upper end of the support 1. Two protective shells 4 are fixedly connected to the upper surface of the table 2. Two servo motors 5 are arranged below the table 2. A wire drawing device 3 is installed at the output end of the servo motor 5. The servo motor 5 is connected to the table 2 through the adjustment structure 7. An auxiliary structure 6 is provided on the upper surface of the table 2, and an adjustment structure 7 is provided on the lower surface of the table 2.

[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The auxiliary structure 6 includes four slides 601, which are divided into two groups of two. Both groups of slides 601 are located on the table surface 2. A slider 609 is slidably connected to the inner wall of the slide 601. A connecting plate 602 is fixedly connected to the side of the slider 609 away from the wire drawing device 3. A screw 608 is threadedly connected to the inner wall of the connecting plate 602. The screw 608 abuts against the table surface 2. A connecting frame 603 is fixedly connected to the upper surface of the slider 609. Several rotating shafts 606 are fixedly connected inside the connecting frame 603. Rollers 604 are rotatably connected to the arc surface of the rotating shafts 606. A spring 610 is provided inside the slide 601. The two ends of the spring 610 are fixedly connected to the slider 609 and the slide 601, respectively. When it is necessary to guide the material, the material is pulled to move it, and then the material comes into contact with the roller 604. The material drives the roller 604 to move, the roller 604 drives the rotating shaft 606 to move, the rotating shaft 606 drives the connecting frame 603 to move, the connecting frame 603 drives the slider 609 to move, the slider 609 drives the connecting plate 602 and the screw 608 to move, the slider 609 drives the spring 610 to stretch, and then the rebound force of the spring 610 drives the roller 604 to abut against the roller 604. When guiding the same type of material, the screw 608 is tightened to fix it. The inner wall of the slide 601 is fixedly connected to the limit rod 611, the limit rod 611 is slidably connected to the slider 609, and the spring 610 is sleeved on the arc surface of the limit rod 611. The limiting rod 611 can limit the spring 610, preventing deformation during use and improving its service life. The roller 604 has several slots 605 evenly distributed on its arc surface. These slots 605 increase the friction between the roller 604 and the material, preventing sliding wear. An anti-slip pad 607, made of rubber, is fixedly connected to the end of the screw 608 closest to the table surface 2. This pad increases the friction between the screw 608 and the table surface 2, preventing slippage during contact.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The adjustment structure 7 includes two connecting plates 71, both of which are fixedly connected to the table surface 2. The lower end of the connecting plate 71 is fixedly connected to a slide rail 72. The inner wall of the slide rail 72 is slidably connected to a moving block 74. The upper surface of the moving block 74 is fixedly connected to a fixed frame 75. The fixed frame 75 is fixedly connected to the servo motor 5. The inner wall of the slide rail 72 is threadedly connected to a lead screw 73. The arc surfaces at both ends of the lead screw 73 are provided with opposite threads. The lead screw 73 is threadedly connected to the moving block 74. One end of the screw 608 is fixedly connected to a turntable 76. When the spacing between the wire drawing devices 3 needs to be adjusted, the turntable 76 is rotated, causing the lead screw 73 to rotate. The lead screw 73 then moves the moving block 74, which slides along the inner wall of the slide rail 72. The moving block 74 moves the fixed frame 75, which in turn moves the servo motor 5. The servo motor 5 then moves the wire drawing device 3. The fixed frame 75 has a circular cross-section and is made of plastic. Plastic is a relatively inexpensive material, which can greatly reduce the manufacturing cost of the fixed frame 75. Several levers 77 are fixedly connected to the arc surface of the turntable 76, and these levers 77 are evenly distributed on the arc surface of the turntable 76. When rotating the turntable 76, the levers 77 can be rotated directly, causing the turntable 76 to rotate. The levers 77 make rotating the turntable 76 more convenient.

[0033] The working principle of the guiding mechanism for a wire drawing machine for irregularly shaped wires provided by this utility model is as follows: When it is necessary to guide the material, the material is pulled to move, and then the material comes into contact with the roller 604. The material drives the roller 604 to move, the roller 604 drives the rotating shaft 606 to move, the rotating shaft 606 drives the connecting frame 603 to move, the connecting frame 603 drives the slider 609 to move, the slider 609 drives the connecting plate 602 and the screw 608 to move, the slider 609 drives the spring 610 to stretch, and then the spring 610 rebounds. The force drives the rollers 604 to abut against each other. When guiding materials of the same type, the screw 608 is tightened for fixation. The limiting rod 611 can limit the spring 610 to prevent deformation during use and improve the service life of the spring 610. The groove 605 can increase the friction between the roller 604 and the material to prevent sliding wear between the material and the roller 604. The protective pad can increase the friction between the screw 608 and the table 2 to prevent slippage when the screw 608 abuts against the table 2 for fixation.

[0034] When it is necessary to adjust the spacing between the wire drawing devices 3, the turntable 76 is rotated to move, the turntable 76 drives the lead screw 73 to rotate, the lead screw 73 drives the moving block 74 to move, the moving block 74 slides on the inner wall of the slide rail 72, the moving block 74 drives the fixed frame 75 to move, the fixed frame 75 drives the servo motor 5 to move, and the servo motor 5 drives the wire drawing device 3 to move. The plastic material is relatively inexpensive, which can greatly reduce the manufacturing cost of the fixed frame 75. When rotating the turntable 76, the handle 77 can be rotated directly, and the handle 77 drives the turntable 76 to rotate. The handle 77 makes it more convenient to rotate the turntable 76.
