[0002] At present, in the production and manufacturing process of steel wire, the wire or bar produced by the steel manufacturer and transported to the standard parts and other metal products manufacturers needs to be drawn by the wire drawing machine, so that the diameter, roundness, internal metallographic structure, surface finish and straightness of the wire or bar meet the raw material processing requirements for the production of standard parts and other metal products. Then the drawn steel wire is taken up by the wire take-up machine, and the drawn steel wire is wound up in piles for easy collection.

[0003] At present, in the process of steel wire drawing, because the steel wire itself is formed from thick to thin by drawing-type surface extrusion of the die, but after a long period of use, the overall drawing hole of the die will inevitably wear, but the degree of wear is relatively small. It is difficult to visually observe the drawn steel wire by manual naked eye observation, which leads to certain quality problems after the diameter of the steel wire changes during drawing. The existing technology relies on manual irregular measurement of the steel wire after drawing, but this method is difficult to provide timely feedback when the steel wire drawing changes.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 8 A wire drawing device for drawing steel wires, comprising a machine body 1; a winding roller 2; a material box 6, used to cool the steel wire after drawing, and use the gravel inside the material box 61 to cool the steel wire with overheated surface to avoid the situation where the filaments break due to the gradual increase in temperature; a drawing component; used to draw the steel wire; a material roller 3, used to collect the drawn steel wire; a driving device, used to drive the drawing component in the machine body 1 to draw the steel wire; a wire drawing change display component 4, used to detect the diameter change of the steel wire after drawing; a tension component 5, used to stretch the steel wire for straightness; the wire drawing change display component 4 includes a merging device and a display device; the merging device calibrates the steel wire after drawing; the display device instantly displays the non-compliant steel wire after drawing.

[0021] The tension assembly 5 includes a double-rotation worm 51, which is rotatably connected to the body 1. The right end of the double-rotation worm 51 is connected to the driving device through a transmission device. Two small worm wheels 53 are meshed on the surface of the double-rotation worm 51. The axis of the small worm wheel 53 is connected to an upper pressure wheel 55 through a shaft, and the lower part of the upper pressure wheel 55 is connected to a lower pressure wheel 56 through a connecting piece. Half of the surface of the double-rotation worm 51 is provided with forward spiral teeth and the other half is reverse spiral teeth, and the two small worm wheels 53 are respectively meshed on the forward spiral teeth and the reverse spiral teeth. The driving device inside the body 1 drives the rotation of the double-rotation worm 51, and then drives the two small worm wheels 53 to rotate. Because the rotation directions of the double-rotation worm 51 are in different states, the two small worm wheels 53 are in a state of relative rotation at this time. In the synchronous state, the two upper pressure wheels 55 are also in a state of relative rotation. At this time, the two ends of the steel wire will be subjected to expansion force, realizing extrusion and stretching at both ends, ensuring that the steel wire in the material box 61 is in a horizontal state, realizing stable transportation and monitoring after wire drawing.

[0022] The back of the small worm wheel 53 is rotatably connected to a bracket 54, which is fixed on the top of the machine body 1. The bottom of the material roller 3 is connected to a large worm wheel 52, which is meshed with the double-helix worm 51. The material roller 3 is rotated by rotating the double-helix worm 51 and the large worm wheel 52, and the rotation of the material roller 3 will coil the steel wire.

[0023] The connecting part includes two upper supporting sleeves 58, and the two upper supporting sleeves 58 are rotatably connected to the upper pressing wheel 55 and the lower pressing wheel 56 respectively. The upper supporting sleeve 58 on the upper pressing wheel 55 is connected with a pull rod 59, and the surface of the pull rod 59 is slidably connected with a pull sleeve 60. The bottom of the pull sleeve 60 is fixed on the upper supporting sleeve 58 connected to the lower pressing wheel 56. The surface of the pull rod 59 is located inside the pull sleeve 60 and is sleeved with a tension spring 57. The upper pressing wheel 55 is connected to the pulling sleeve 60 by means of a pulling rod 59 connected to the upper supporting sleeve 58, and the pulling sleeve 60 is connected to the lower pressing wheel 56. The upper pressing wheel 55 and the lower pressing wheel 56 are in an elastically connected state by means of a tension spring 57, so the steel wire will be squeezed by the upper pressing wheel 55 and the lower pressing wheel 56, and abutted between the upper pressing wheel 55 and the lower pressing wheel 56. As the upper pressing wheel 55 and the lower pressing wheel 56 rotate, tension is applied. The overall principle is like a person pulling the steel wire with both hands to keep it in a horizontal and straight state. Because if the steel wire is not in a horizontal and straight state and is in a bent state, the bent part of the steel wire will squeeze the fan-shaped sleeve 401 to control its change, so the horizontality of the steel wire must be ensured.

[0024] The merging device includes a plug die 402, on which three T-shaped slides are provided, and fan-shaped sleeves 401 are slidably connected to the three T-shaped slides, and arc springs 403 are arranged around the three fan-shaped sleeves 401, and side top devices 404 are arranged on the fan-shaped sleeves 401 sliding on both sides of the plug die 402, and the fan-shaped sleeves 401 in the middle of the plug die 402 are in contact with the display device. The three fan-shaped sleeves 401 form a circular sleeve, and the circular hole in the middle is the standard diameter of the steel wire. When the steel wire is drawn, the diameter changes. Because of the wear of the mold, the direction of change of the steel wire will only be larger. When the large-diameter steel wire passes through the fan-shaped sleeve 401, the three fan-shaped sleeves 401 will expand and move, and open the arc springs 403. Therefore, the standard circle formed by the three fan-shaped sleeves 401 at this time is to perform standardized monitoring of the steel wire after drawing, so as to achieve consistency in the drawing process.

[0025] The side top device 404 includes a sliding plate 4041, which is connected to the fan-shaped sleeve 401. The sliding plate 4041 is provided with teeth, and a small gear 4042 is meshed on the teeth. A rocker arm 4043 is fixedly connected to the small gear 4042. The rocker arm 4043 is connected to a connecting rod 4044 through a connecting rod. The top of the connecting rod 4044 is rotatably connected to a top rod 4045, and the top rod 4045 is slidably connected to the insert mold 402. If the side diameter of the steel wire changes, the fan-shaped sleeves 401 on both sides will be squeezed to control the sliding of the fan-shaped sleeves 401 on both sides, thereby driving the movement of the sliding sheet 4041, and through the meshing of the gears, driving the rocker rod 4043 to rotate, and then driving the connecting rod 4044 to swing up through the connection of the connecting rod, thereby pushing the top rod 4045 to slide upward, and the upward movement of the top rod 4045 will abut against the abutment 414, and finally driving the rotation of the center rod 405, realizing the channel connection of the ink, and also realizing the coloring display, so the whole equipment monitors the diameter of the steel wire drawing in three directions.

[0026] The material box 6 includes a material box 61, and the left and right inner walls of the material box 61 are installed with a left cone sleeve 62 and a right cone sleeve 63. The material box 61 is set on the machine body 1, and a positioning frame 64 is connected to the right side of the material box 61. Gravel for cooling the steel wire is set inside the material box 61. The grit inside the material box 61 is used to cool the steel wire with overheated surface to avoid the situation that the filament breaks due to the gradual increase in temperature. The left cone sleeve 62 and the right cone sleeve 63 are set to prevent the grit from leaking out of the material box 61. The extended design of the left cone sleeve 62 and the right cone sleeve 63 reduces the channel for the grit to overflow.

[0027] The display device includes a center rod 405, which is rotatably connected to the positioning frame 64. The positioning frame 64 is connected to an ink box 406 through a branch pipe 407. A rotating arc plate 408 is slidably connected to the branch pipe 407. The left side of the rotating arc plate 408 is connected to the center rod 405. A balance spring 410 is connected to the bottom of the rotating arc plate 408. The bottom of the balance spring 410 is connected to the positioning frame 64. The left side of the center rod 405 is slidably connected to a top plate 409 through a T-slot. The bottom of the top plate 409 is connected to a support frame 414. An outlet groove 411 is opened on the rotating arc plate 408. A flow channel is arranged inside the positioning frame 64. When a large-diameter steel wire passes through the fan-shaped sleeve 401 After that, the three fan-shaped sleeves 401 will expand and move, stretching the arc spring 403. If the upper part of the mold is worn, the steel wire will be thicker at the top, which will drive the fan-shaped sleeve 401 above to squeeze and rise, and then the fan-shaped sleeve 401 will contact the support frame 414, and the center rod 405 will rotate through the connection of the top plate 409. At this time, under the effect of the lever principle, the ink inside the ink box 406 will flow to the inside of the positioning frame 64 through the branch pipe 407, and then drip from the top of the steel wire through the flow channel and adhere to the surface of the steel wire. At this time, as long as the operator sees the coloring on the steel wire, it means that the diameter of the steel wire has changed, and the mold needs to be repaired and replaced. A collection groove 412 is opened inside the positioning frame 64, and the collection groove 412 is connected to the collection box 413 through a pipeline. The excess ink will enter the inside of the collection groove 412 and flow into the inside of the collection box 413 through the pipeline to collect the excess ink.

[0028] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0029] Working principle: First, in the initial stage of operation, the equipment needs to rely on manual pulling of the steel wire to pass it through the drawing assembly. The drawing assembly in this technical solution is an existing known technology. For details, please refer to the principle of the wire drawing machine. The plastic deformation characteristics of metal materials are used to deform the metal materials through drawing and compression to obtain the required cross-sectional shape and dimensional accuracy. Specifically, the wire drawing machine feeds the metal wire into the drum through the feeding mechanism. The drum rotates and applies a certain tension to make the wire close to the wire drawing disk. Under the action of the drawing mechanism, the metal material undergoes multiple drawing and cooling, gradually reducing the cross-sectional size, and finally reaches the desired filament state. After the steel wire is drawn, its end passes through the middle of the upper pressing wheel 55 and the lower pressing wheel 56 and enters the interior of the material box 61. The sand inside the material box 61 is then used to cool the overheated steel wire on the surface to avoid the filament breaking due to the gradual increase in temperature. The end of the steel wire then passes between another set of upper pressing wheels 55 and lower pressing wheels 56 on the right side, and is then wound around the material roller 3. The driving device inside the machine body 1 will drive the double-rotation worm 51 to rotate through the transmission device, and the transmission device is specifically a toothed belt transmission method, which drives the rotation of the double-rotation worm 51, and then The two small worm gears 53 are driven to rotate. Since the rotation directions of the double-helix worm 51 are in different states, the two small worm gears 53 are in a state of relative rotation. In the synchronous state, the two upper pressure wheels 55 are also in a state of relative rotation. At this time, both ends of the steel wire will be subjected to expansion force, realizing extrusion and stretching at both ends, ensuring that the steel wire in the material box 61 is in a horizontal state, but the whole steel wire is in a state of being transported to the right, because the material roller 3 is always in a rotating state, and the rotation of the double-helix worm 51 synchronously drives the rotation of the large worm gear 52, so the steel wire will be always in a winding state. The reason why the steel wire is subjected to tension is also due to the elastic pulling provided by the tension spring 57, because the upper pressure wheel 55 is connected to the pulling sleeve 60 by the pulling rod 59 connected to the upper support sleeve 58, and the pulling sleeve 60 is connected to the lower pressure wheel 56, and the upper pressure wheel 55 and the lower pressure wheel 56 are in an elastically connected state by the tension spring 57, so the steel wire will be squeezed by the upper pressure wheel 55 and the lower pressure wheel 56, and abut against the upper pressure wheel 55 and the lower pressure wheel 56. As the upper pressure wheel 55 and the lower pressure wheel 56 rotate, tension is applied. The overall principle is like a person pulling the steel wire with both hands to keep it in a horizontal and straight state.The three sector sleeves 401 form a circular sleeve, and the circular hole in the middle is the standard diameter of the steel wire. When the steel wire is drawn, the diameter changes. Because of the wear of the mold, the change direction of the steel wire will only be larger. When the large-diameter steel wire passes through the sector sleeve 401, the three sector sleeves 401 will expand and move, and open the arc spring 403. If the upper part of the mold is worn, the steel wire will be thicker at the upper part, thereby driving the sector sleeve 401 above to be squeezed and raised, and then the sector sleeve 401 contacts the bracket 414, and drives the center rod 405 to move forward through the connection of the top plate 409. The rotating arc plate 408 is rotated. At this time, under the effect of the lever principle, the rotating arc plate 408 is pressed down in the opposite direction to slide the outlet slot 411 on the rotating arc plate 408 into the inside of the branch pipe 407. Then the branch pipe 407 is turned on, and the ink in the ink box 406 flows through the branch pipe 407 to the inside of the positioning frame 64, and then drips from the top of the steel wire through the flow channel and adheres to the surface of the steel wire. The excess ink enters the inside of the collecting slot 412 and flows into the inside of the collecting box 413 through the pipeline, so as to color the steel wire and realize the change of the steel wire. The operator can determine that the diameter of the steel wire has changed during the wire drawing process according to the position of the colored section, and then repair or replace the mold. If the side diameter of the steel wire changes, the fan-shaped sleeves 401 on both sides will be squeezed to control the sliding of the fan-shaped sleeves 401 on both sides, thereby driving the movement of the sliding sheet 4041, and through the meshing of the gears, the swing rod 4043 is driven to rotate, and then the connecting rod 4044 is driven to swing up through the connection of the connecting rod, thereby pushing the top rod 4045 to slide upward, and the upward movement of the top rod 4045 will interact with the support frame 414. The abutment eventually drives the rotation of the center rod 405, realizes the connection of the ink channel, and also realizes the coloring. Therefore, the whole device monitors the diameter of the drawn wire in three directions to avoid changes in a single direction, which cannot achieve the monitoring effect. If the diameter of the steel wire as a whole is increased, that is, the perforation of the mold becomes larger as a whole, it will trigger the three fan-shaped sleeves 401 to move synchronously, and then synchronously use the lever principle to control the opening of the ink channel. Therefore, the whole device realizes the monitoring of a single position and the detection of changes in multi-directional positions, thereby ultimately ensuring the quality of the steel wire after drawing.
