[0014] The present invention provides a high-efficiency multi-aperture wire drawing device for electromagnetic wires. It has the following beneficial effects:

[0015] (1) In the process of drawing the electromagnetic wire, the traction roller is always in contact with the electromagnetic wire under the action of the spring and the sliding block during the process of changing the tension of the electromagnetic wire, so that the tension of the electromagnetic wire is kept stable during the drawing process, ensuring that the drawing process of the electromagnetic wire is uniform and continuous. At the same time, the tension of the electromagnetic wire of different thicknesses can be controlled by replacing the sliding frame, thereby increasing the applicability of the equipment and improving the efficiency of the electromagnetic wire drawing.

[0016] (2) In the electromagnetic wire high-efficiency multi-aperture wire drawing device, the movement of the sliding block drives the limit rod to disengage from the limit groove and be re-limited, which can effectively prevent the sliding block from being in a shaking state, thereby causing the tension of the electromagnetic wire to change unsteadily, thereby causing uneven stretching of the electromagnetic wire. At the same time, the movement of the sliding block drives the receiving rod to squeeze the block.

[0017] (3) In the electromagnetic wire high-efficiency multi-aperture wire drawing device, when the electromagnetic wire moves laterally during the winding process, it will drive the driven traction wheel to move, and the movement of the driven traction wheel maintains the stability of the electromagnetic wire during the winding process. At the same time, when the electromagnetic wire is finished drawing or the electromagnetic wire breaks, the driven traction wheel loses pressure and rebounds. Under the action of the rotating rod and the connecting rod, the lifting clamp moves downward and clamps the electromagnetic wire, preventing the electromagnetic wire from changing shape or rebounding in size due to the release of internal stress, maintaining its stable shape and size, improving production efficiency and product quality, and reducing subsequent maintenance costs.

[0027] See also Figure 1-Figure 4 An embodiment of the present invention is: an electromagnetic wire high-efficiency multi-aperture wire drawing device, including a workbench 1, and also including an adjusting device; wherein a wire-releasing mechanism 2 is fixedly installed above the workbench 1, a wire-drawing mechanism 3 is fixedly installed above the workbench 1, a support plate 4 is fixedly installed above the workbench 1, and a winding mechanism 5 is arranged on the surface of the support plate 4; wherein the adjusting device includes an adjusting rod 6, a reciprocating screw rod 7, a sliding frame 8, a rotating plate 9, a limiting plate 10, a sliding block 11, a receiving shaft 12, a traction roller 13 and a lifting rod 14, a placement groove is opened on the surface of the support plate 4, the adjusting rod 6 is fixedly installed on the inner wall of the placement groove, and the reciprocating screw rod 7 rotates through the support plate 4. The left and right walls of the plate 4, the sliding frame 8 is sleeved on the circumferential surface of the adjusting rod 6, the rotating plate 9 is rotatably installed on the side of the sliding frame 8, the limiting plate 10 is slidably installed on the side of the sliding frame 8, the surface of the sliding frame 8 is provided with a slide groove 1, the sliding block 11 is slidably installed inside the slide groove 1, the receiving shaft 12 rotates and passes through the left and right walls of the sliding block 11, the traction roller 13 is fixedly installed on the circumferential surface of the receiving shaft 12, the lifting rod 14 slides through the upper and lower walls of the sliding frame 8, and the lower part of the lifting rod 14 is fixedly connected to the sliding block 11, and the traction roller 13 always keeps in contact with the electromagnetic wire, so that the tension of the electromagnetic wire is maintained stable during the wire drawing process, ensuring that the stretching process of the electromagnetic wire is uniform and continuous.

[0028] The top of the inner wall of the slide groove 1 is connected to the sliding block 11 through a spring, the reciprocating screw rod 7 and the winding mechanism 5 are connected through a transmission belt, the sliding frame 8 and the reciprocating screw rod 7 are threadedly engaged, and the sliding frame 8 is rotated to engage with the threaded groove on the surface of the reciprocating screw rod 7. When drawing electromagnetic wires of different thicknesses, different spring elastic coefficients can be replaced by replacing different sliding frames 8, thereby increasing the applicability of the equipment and improving the efficiency of electromagnetic wire drawing.

[0029] The surface of the limit plate 10 is set as a beveled surface 1, and the rotating plate 9 moves through the beveled surface 1 to squeeze the limit plate 10 to move. A clockwork spring 1 is set between the limit plate 10 and the sliding frame 8, and the clockwork spring 1 can drive the limit plate 10 to reset to fix the rotating plate 9.

[0030] When this embodiment is working: the wire drawing mechanism 3 and the winding mechanism 5 are started, and the wire drawing work of electromagnetic wires of different thicknesses is realized through the wire dies with different apertures on the surface of the wire drawing mechanism 3, and at the same time, the sliding frame 8 is rotated to engage with the threaded groove on the surface of the reciprocating screw rod 7, and then the rotating plate 9 is rotated and the limit plate 10 is squeezed to move. After the limit plate 10 moves, it is reset to limit the rotating plate 9, and then the electromagnetic wire after wire drawing is passed through the traction roller 13 and wound under the action of the winding mechanism 5. When the tension of the electromagnetic wire changes during the wire drawing process, it moves upward or downward under the action of the traction roller 13, and the movement of the traction roller 13 drives the receiving shaft 12 to move The movement of the receiving shaft 12 drives the sliding block 11 to move, and the movement of the sliding block 11 drives the lifting rod 14 to move. The movement of the lifting rod 14 causes the sliding block 11 to squeeze or stretch the spring.

At the same time, when drawing electromagnetic wires of different thicknesses, different spring elastic coefficients can be replaced by replacing different sliding frames 8, thereby increasing the applicability of the equipment and improving the efficiency of electromagnetic wire drawing.

[0031] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the surface of the sliding block 11 is provided with a stabilizing device for maintaining the tension stability of the electromagnetic wire, and also includes a clamping device, the stabilizing device includes a limit rod 151, a receiving rod 152, a stopper 153, a receiving block 154 and a button 155, a second slide groove is provided on the surface of the sliding block 11, the limit rod 151 is slidably installed in the interior of the second slide groove, the receiving rod 152 is fixedly installed on the side of the sliding block 11, a third slide groove is provided on the surface of the sliding frame 8, the stopper 153 is slidably installed in the interior of the third slide groove, the receiving block 154 is fixedly installed on the side of the sliding frame 8, and the button 155 is fixedly installed above the receiving block 154, the button 155 is electrically connected to the winding mechanism 5, and the button 155 is electrically connected to the wire drawing mechanism 3, so as to limit the moving speed of the sliding block 11, avoid sudden changes in tension and maintain a smooth transition of the tension change, and the instantaneous change will cause the sliding block 11 to move too fast, resulting in direct breakage of the electromagnetic wire, thereby increasing the production cost.

[0032] The limit rod 151 is connected to the inner wall of the second slide groove by a telescopic elastic rod 156, and the telescopic elastic rod 156 can drive the limit rod 151 to reset. The stop block 153 is connected to the inner wall of the third slide groove by a spring piece 157, and the spring piece 157 can drive the stop block 153 to reset. The surface of the stop block 153 is set as an arc surface one, and a limit groove is provided on the inner wall of the first slide groove. The limit rod 151 moves out of the limit groove and contacts with the next limit groove and is limited, which can effectively prevent the sliding block 11 from being in a shaking state all the time, thereby making the tension of the electromagnetic wire change unpredictably.

[0033] The clamping device includes a U-shaped rod 161, an inclined rod 162, a rotating rod 163, a driven traction wheel 164, a connecting rod 165, a lifting clamp plate 166 and a fixed rod 167. The U-shaped rod 161 is fixedly installed on the side of the sliding block 11, the inclined rod 162 is rotatably installed on the circumferential surface of the U-shaped rod 161, the rotating rod 163 rotates and passes through the left and right walls of the inclined rod 162, the driven traction wheel 164 is slidably installed on the circumferential surface of the rotating rod 163, the connecting rod 165 is rotatably installed on the circumferential surface of the rotating rod 163, the lifting clamp plate 166 slides through the upper and lower walls of the U-shaped rod 161, and the fixed rod 167 is fixedly installed on the side of the lifting clamp plate 166. The lifting clamp plate 166 moves downward and clamps the electromagnetic wire under the action of the driven traction wheel 164, so as to prevent the electromagnetic wire from changing in shape or rebounding in size due to the release of internal stress after wire drawing, maintain its stable shape and size, improve production efficiency and product quality, and reduce subsequent maintenance costs.

[0034] One end of the connecting rod 165 away from the rotating rod 163 is rotatably connected to the fixed rod 167. A second spring is provided between the inclined rod 162 and the U-shaped rod 161, and the second spring can drive the inclined rod 162 to reset.

[0036] When this embodiment is working: when the sliding block 11 moves, it drives the limiting rod 151 to move, and the limiting rod 151 moves out of the limiting groove and contacts with the next limiting groove and is limited, which can effectively prevent the sliding block 11 from being in a shaking state all the time, thereby causing the tension of the electromagnetic wire to change unpredictably, thereby causing the electromagnetic wire to be stretched unevenly, resulting in instability in the diameter, surface smoothness, mechanical properties, etc. of the finished product. At the same time, the sliding block 11 moves and drives the receiving rod 152 to move, and the receiving rod 152 moves to contact and squeeze the stopper 153 to move, and the stopper 153 moves to squeeze the telescopic elastic rod 156 and then resets, thereby limiting the moving speed of the sliding block 11, avoiding sudden changes in tension and maintaining a smooth transition of the tension change. Instantaneous changes will cause the sliding block 11 to move too fast, resulting in direct breaking of the electromagnetic wire, thereby increasing production costs. At the same time, when the tension is too large, the sliding block 11 moves downward to contact and squeeze the button 155. The button 155 is pressed to disconnect the circuit and stop the wire drawing mechanism 3 and the winding mechanism 5 from working, thereby avoiding the equipment from continuing to work and further increasing production costs, and reducing subsequent maintenance costs.

[0037] During the winding process of the electromagnetic wire, it passes through the driven traction wheel 164 and drives it to move and tilt. The movement of the driven traction wheel 164 drives the rotating rod 163 to move, and the rotating rod 163 moves the inclined rod 162 to move. When the electromagnetic wire moves horizontally, it drives the driven traction wheel 164 to move. The movement of the driven traction wheel 164 maintains the stability of the electromagnetic wire during the winding process. At the same time, when the electromagnetic wire is drawn or the electromagnetic wire is broken, the inclined rod 162 is reset and rotated under the action of the spring spring 2. The rotation of the inclined rod 162 drives the connecting rod 165 to move. The movement of the connecting rod 165 drives the fixed rod 167 to move downward. The fixed rod 167 moves downward and drives the lifting clamp 166 to move downward. The lifting clamp 166 moves downward and clamps the electromagnetic wire under the action of the driven traction wheel 164 to prevent the electromagnetic wire from changing its shape or rebounding in size due to the release of internal stress after drawing, so as to maintain its stable shape and size, improve production efficiency and product quality, and reduce subsequent maintenance costs.
