[0013] Compared with the related art, a wire drawing machine capable of controlling tension provided by the present utility model has the following beneficial effects:

[0014] The present utility model provides a wire drawing machine capable of controlling tension. Pull the pressure roller upward, and then press the middle position of the pressure roller against the wire installed on the wire drawing machine body. At this time, the wire can be pressed down by the weight of the first sliding plate and corresponding parts, so as to adjust the tension of the wire and make the wire in a taut state. At this time, the spring can press down the first sliding plate through the elastic force by the blocking and limiting of the second sliding plate. At this time, the downward pressure of the pressure roller can be increased, so as to ensure that the wire is in a taut state. When the elastic force of the spring is not enough under normal circumstances, the first rotating block can be rotated to drive the first screw rod to drive the extrusion piece to squeeze the second sliding plate downward. At this time, the first sliding plate can generate a greater downward pressure by squeezing the spring through the second sliding plate. The tension of the wire can be controlled through this mechanism, preventing the wire from being damaged during processing, and being very convenient to use. By rotating the second rotating block, the second screw rod can move along the first side plate. At this time, the second screw rod can drive the baffle to slide along the second limiting rod through the limiting ring and the limiting piece, so as to adjust the position of the baffle. By adjusting the position of the baffle, the baffle can limit the first sliding plate. By limiting the first sliding plate, it can prevent the pressure roller from breaking the wire due to excessive pressure. Through this mechanism, the equipment can work more stably.

A wire drawing machine with controllable tension includes: the main body 1 of the wire drawing machine;

[0021] A fixed frame 2 is arranged at the upper end of the main body 1 of the wire drawing machine. The fixed frame 2 is fixedly connected to the upper end of the main body 1 of the wire drawing machine. Two groups of first limiting rods 3 are fixedly connected inside the fixed frame 2. The first sliding plate 4 is slidably connected to the circumferential side of the first limiting rod 3. The second sliding plate 5 is slidably connected to the circumferential side of the first limiting rod 3. A spring 6 is fixedly connected between the second sliding plate 5 and the first sliding plate 4. The first lead screw 7 is threadedly connected to the upper end of the fixed frame 2. The bottom end of the first lead screw 7 is fixedly connected with an extrusion piece 8. The upper end of the first lead screw 7 is fixedly connected with a first rotating block 9. The back surface of the first sliding plate 4 is fixedly connected with a connecting rod 10. The rear end of the connecting rod 10 is rotatably connected with a pressing roller 11.

[0022] A first side plate 12 is fixedly connected to the right side of the fixed frame 2. A second side plate 13 is fixedly connected to the right side of the fixed frame 2.

[0023] Two groups of second limiting rods 14 are fixedly connected between the first side plate 12 and the second side plate 13.

[0024] The second lead screw 15 is threadedly connected to the upper end of the first side plate 12. A limiting ring 16 is fixedly connected to the circumferential side of the second lead screw 15.

[0025] The bottom end of the second lead screw 15 is fixedly connected with a limiting piece 17. The upper end of the second lead screw 15 is fixedly connected with a second rotating block 18.

[0026] A baffle 19 is slidably connected to the circumferential side surface of the second limiting rod 14. The baffle 19 is located between the limiting ring 16 and the limiting piece 17, and the baffle 19 is rotatably connected to the second lead screw 15. The arrangement of the baffle 19 facilitates the limitation of the first sliding plate 4.

[0027] The working principle of a wire drawing machine capable of controlling tension provided by the present utility model is as follows:

[0028] First step: When in use, the pressure roller 11 is pulled upward, and then the middle position of the pressure roller 11 is pressed against the wire installed on the wire drawing machine body 1. At this time, the wire can be pressed down by the weight of the first sliding plate 4 and corresponding parts, thereby adjusting the tension of the wire to make the wire in a taut state. At this time, the spring 6 presses down the first sliding plate 4 through the elastic force by the blocking and limitation of the second sliding plate 5. At this time, the downward pressure of the pressure roller 11 can be increased, so as to ensure that the wire is in a taut state. When the elastic force of the spring 6 is not enough under normal circumstances, the first rotating block 9 can be rotated to drive the first lead screw 7 to drive the pressing piece 8 to press down the second sliding plate 5. At this time, the first sliding plate 4 can generate a greater downward pressure by the second sliding plate 5 pressing the spring 6.

[0029] Second step: By rotating the second rotating block 18, the second lead screw 15 can move along the first side plate 12. At this time, the second lead screw 15 can drive the baffle 19 to slide along the second limiting rod 14 through the limiting ring 16 and the limiting piece 17, so as to adjust the position of the baffle 19. By adjusting the position of the baffle 19, the baffle 19 can limit the first sliding plate 4, and by limiting the first sliding plate 4, it can prevent the wire from being broken by the pressure roller 11 due to excessive pressure.

[0030] Compared with the related technology, a wire drawing machine capable of controlling tension provided by the present utility model has the following beneficial effects:

[0031] Pull up the pressure roller 11, and then press the middle position of the pressure roller 11 against the wire installed on the wire drawing machine body 1. At this time, the wire can be pressed down by the weight of the first sliding plate 4 and the corresponding parts, so as to adjust the tension of the wire and make the wire in a taut state. At this time, the spring 6 can press down the first sliding plate 4 through the elastic force by the blocking and limiting of the second sliding plate 5. At this time, the downward pressure of the pressure roller 11 can be increased, so as to ensure that the wire is in a taut state. When the elastic force of the spring 6 is insufficient under normal circumstances, the first screw rod 7 can be driven to press down the second sliding plate 5 by rotating the first rotating block 9. At this time, the first sliding plate 4 can generate a greater downward pressure by pressing the spring 6 through the second sliding plate 5. The tension of the wire can be controlled by this mechanism to prevent the wire from being damaged during processing, which is very convenient to use. By rotating the second rotating block 18, the second screw rod 15 can move along the first side plate 12. At this time, the second screw rod 15 can drive the baffle 19 to slide along the second limiting rod 14 through the limiting ring 16 and the limiting piece 17, so as to adjust the position of the baffle 19. By adjusting the position of the baffle 19, the baffle 19 can limit the first sliding plate 4. By limiting the first sliding plate 4, the pressure roller 11 can be prevented from breaking the wire due to excessive pressure. The equipment can work more stably through this mechanism.
