Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing technology, specifically a metal wire drawing device with adjustable wire threading position. Background Technology

[0002] Wire drawing machines, also known as wire drawing machines or wire drawing machines, are widely used mechanical equipment in industrial applications. They are widely used in industries such as machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, and wire and cable. Wire drawing machines can be classified according to their uses, such as metal wire drawing machines, plastic wire drawing machines, and bamboo and wood wire drawing machines. The purpose of metal wire drawing machines is to draw wires or bars produced by steel manufacturers and transported to standard parts and other metal product manufacturing enterprises. This process ensures that the diameter, roundness, internal metallographic structure, surface finish, and straightness of the wires or bars meet the raw material processing requirements for standard parts and other metal product manufacturing. Therefore, the quality of the wire or bar pretreatment by the wire drawing machine directly affects the quality of standard parts and other metal product manufacturing.

[0003] Metal wire drawing machines are widely used in the production and pre-processing of metal products such as steel wire, rope wire, prestressed steel wire, and standard parts, in order to improve the product quality of manufacturing enterprises.

[0004] However, current wire drawing machines have some shortcomings. Before drawing, the tension needs to be adjusted. Different thicknesses of copper wire require different tensions during stretching. Excessive tension may cause the copper wire to pull or break, while insufficient tension will affect the quality of the copper wire. In existing wire tension adjustment technology, the position of the tension spring is moved to change the tension. The elasticity of the tension spring is fixed. Different specifications of copper wire require different tensions, and the tension spring needs to be replaced frequently, resulting in cumbersome operation. Utility Model Content

[0005] To address the problems of the prior art, this invention provides a wire drawing device with adjustable wire threading position, which can conveniently adjust the tension of the wire, thereby improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire drawing device with adjustable wire threading position, comprising a support platform, a first drawing wheel rotatably connected to the support platform, a second drawing wheel rotatably connected to the support platform, a drawing die disposed between the first and second drawing wheels, and a winding mechanism disposed downstream of the second drawing wheel. A pretreatment component for cleaning impurities on the surface of the wire is disposed upstream of the first drawing wheel. An ultrasonic cleaning tank for cleaning the wire is disposed downstream of the drawing die. A tensioning mechanism for tensioning the wire is disposed upstream of the second drawing wheel. The tensioning mechanism includes a first slider and a second slider, a first tensioning wheel rotatably connected to the first slider, a second tensioning wheel rotatably connected to the second slider, and a tension adjustment mechanism for driving the first and second sliders to move up and down. Both the first and second sliders are slidably connected to the support platform.

[0007] With the above structural design, the tension of the metal wire can be adjusted by moving the first tensioning wheel and the second tensioning wheel, making the operation convenient and simple.

[0008] Preferably, the pretreatment assembly includes a pretreatment block, a decontamination hole formed on the pretreatment block, a left clamping plate and a right clamping plate for clamping the pretreatment block, positioning bolts symmetrically arranged on the left clamping plate and the right clamping plate, and a guide wheel rotatably connected to the left clamping plate. The left clamping plate and the right clamping plate are each provided with a slot that matches the pretreatment block, and the support platform is provided with a positioning hole that matches the positioning bolt.

[0009] With the above structural design, the diameter of the metal wire is the same as the diameter of the cleaning hole. After the metal wire passes through the cleaning hole, the impurities attached to the surface of the metal wire will be trapped outside the cleaning hole, thereby cleaning the metal wire. The operation is simple and convenient.

[0010] Preferably, multiple positioning holes are provided, and the positioning hole array is distributed on the support platform, with the spacing between adjacent positioning holes being equal to the spacing between positioning bolts.

[0011] The above structural design allows for adjustment of the position of the pretreatment components based on the wire threading location, thus enabling better wire threading.

[0012] Preferably, the ultrasonic cleaning tank is provided with multiple guide wheels inside.

[0013] By adopting the above structural design, the length of the metal wire inside the ultrasonic cleaning tank is increased, thereby increasing the residence time of the metal wire in the ultrasonic cleaning tank, and thus cleaning the metal wire more thoroughly.

[0014] Preferably, the tension adjustment mechanism includes a first screw threaded through the first slider, a second screw threaded through the second slider, a first gear fixedly connected to the first screw, and a second gear fixedly connected to the second screw. The first gear and the second gear mesh with each other. Both the first screw and the second screw are rotatably connected to the support platform. The upper end of the second screw is fixedly connected to a hexagonal drive head.

[0015] With the above structural design, rotating the second screw causes the second gear to rotate the first gear, which in turn causes the first and second sliders to move simultaneously, and subsequently causes the first and second tensioning wheels to move simultaneously, thus making it easier to adjust the tension of the metal wire.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This device, by setting a first tensioning wheel and a second tensioning wheel, can more conveniently adjust the tension of the metal wire; by setting a pre-treatment component, this device can first clean the metal wire. After the metal wire passes through the ultrasonic cleaning tank, the debris generated after drawing can be removed, improving the cleanliness of the metal wire surface and reducing the scratches on the metal wire surface by debris.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a technical solution: a wire drawing device with adjustable wire threading position, including a support platform 3, a first drawing wheel 1 rotatably connected to the support platform 3, a second drawing wheel 2 rotatably connected to the support platform 3, a drawing die 4 disposed between the first drawing wheel 1 and the second drawing wheel 2, and a winding mechanism disposed downstream of the second drawing wheel 2. The winding mechanism is used to wind the drawn metal wire into a metal wire coil. A pretreatment component for cleaning impurities on the surface of the metal wire is disposed upstream of the first drawing wheel 1, an ultrasonic cleaning tank 5 for cleaning the metal wire is disposed downstream of the drawing die 4, and a tensioning mechanism for tensioning the metal wire is disposed upstream of the second drawing wheel 2. The tensioning mechanism includes a first slider 61 and a second slider 62, a first tensioning wheel 63 rotatably connected to the first slider 61, a second tensioning wheel 64 rotatably connected to the second slider 62, and a tension adjustment mechanism for driving the first slider 61 and the second slider 62 to move up and down. The first slider 61 and the second slider 62 are both slidably connected to the support platform 3.

[0023] Please see Figure 2 In this embodiment, the first tensioning wheel 63 moves upward and the second tensioning wheel 64 moves downward. The first tensioning wheel 63 moves in the opposite direction to the second tensioning wheel 64, which can quickly tighten the metal wire and change the tension of the metal wire.

[0024] The pretreatment assembly includes a pretreatment block 71, a cleaning hole 72 formed on the pretreatment block 71, a left clamping plate 73 and a right clamping plate 74 for clamping the pretreatment block 71, positioning bolts 75 symmetrically arranged on the left clamping plate 73 and the right clamping plate 74, and a guide wheel 76 rotatably connected to the left clamping plate 73. The left clamping plate 73 and the right clamping plate 74 are both provided with slots that match the pretreatment block 71, and the support platform 3 is provided with positioning holes 77 that match the positioning bolts 75.

[0025] According to production needs, multiple pretreatment blocks 71 are made, and each pretreatment block 71 corresponds to a metal wire with a certain aperture.

[0026] Multiple positioning holes 77 are provided, and the positioning holes 77 are arrayed on the support platform 3. The spacing between adjacent positioning holes 77 is equal to the spacing between positioning bolts 75.

[0027] like Figure 1 , Figure 2 As shown, the positioning holes 77 are arranged in 6 rows and 2 columns. When the metal wire is passed into the device from top to bottom, the axial direction of the cleaning hole 72 becomes vertical. Then, the positioning bolts 75 are inserted into the two corresponding positioning holes 77 in the first row. When the metal wire is passed into the device from left to right, the axial direction of the cleaning hole 72 becomes horizontal. Then, according to the height of the wire passing position, the positioning bolts 75 are inserted into the two corresponding positioning holes 77 in the first column.

[0028] The ultrasonic cleaning tank 5 is internally equipped with multiple guide wheels 51. The ultrasonic cleaning tank 5 is fixedly connected to the support platform 3, and the guide wheels 51 are rotatably connected to the inner wall of the ultrasonic cleaning tank 5. Figure 2 As shown, in order to increase the residence time of the metal wire in the ultrasonic cleaning tank 5, multiple guide wheels 51 are provided. The guide wheels 51 are arranged in an array inside the ultrasonic cleaning tank 5. Two rows of guide wheels 51 are provided on the inner side wall of the ultrasonic cleaning tank 5. The metal wire passes through the guide wheels 51 from top to bottom.

[0029] The tension adjustment mechanism includes a first screw 601 threaded onto the first slider 61, a second screw 602 threaded onto the second slider 62, a first gear 603 fixedly connected to the first screw 601, and a second gear 604 fixedly connected to the second screw 602. The first gear 603 meshes with the second gear 604. Both the first screw 601 and the second screw 602 are rotatably connected to the support platform 3. A hexagonal drive head 605 is fixedly connected to the upper end of the second screw 602. The threads of the first screw 601 and the second screw 602 are in the same direction. When the operator uses a wrench to rotate the second screw 602, the second gear 604, which meshes with the first gear 603, rotates accordingly. The rotation directions of the first gear 603 and the second gear 604 are opposite. The first slider 61 moves upward, and the second slider 62 moves downward. The first tension wheel 63 then moves in the opposite direction relative to the second tension wheel 64, thereby adjusting the tension of the wire.

[0030] The wire drawing die 4 is arranged between the wire drawing die bases 41. The wire drawing die bases 41 are symmetrically arranged on both sides of the wire drawing die 4. The wire drawing die bases 41 have die grooves that match the wire drawing die 4. The wire drawing die bases 41 are fitted with fixing bolts 42. The support platform 3 has threaded holes that match the fixing bolts 42.

[0031] Working principle: First, the operator selects the pretreatment block 71 corresponding to the wire aperture. Then, the operator installs the pretreatment block 71 into the slots on the left clamping plate 73 and the right clamping plate 74. Next, the operator inserts the positioning bolts 75 into the left clamping plate 73 and the right clamping plate 74, and inserts the positioning bolts 75 into the corresponding positioning holes 77 according to the wire threading position. The operator then tightens the bolts with nuts. Next, the operator selects the model of the wire drawing die 4 and installs the wire drawing die 4 into the die slot on the wire drawing die base 41. The operator then inserts the fixing bolts 42 into the wire drawing die base 41 and into the corresponding threaded holes on the support platform 3. Finally, the operator sequentially passes the wire through the cleaning holes 72 and 72 on the pretreatment block 71. The device consists of a wire drawing wheel 1, a second wire drawing wheel 2 connected to a support platform 3, a wire drawing die 4, a guide wheel 51 inside an ultrasonic cleaning tank 5, a first tensioning wheel 63, a second tensioning wheel 64, and a second wire drawing wheel 2. Finally, the metal wire is connected to the winding mechanism. When the operator uses a wrench to turn the second screw 602, the second gear 604, which meshes with the first gear 603, rotates accordingly. The rotation directions of the first gear 603 and the second gear 604 are opposite. The first slider 61 moves upward, and the second slider 62 moves downward. The first tensioning wheel 63 then moves in the opposite direction to the second tensioning wheel 64, thereby adjusting the tension of the metal wire. Once the tension of the metal wire is adjusted, the device can be started to perform the wire drawing operation.
