[0002] Stainless steel wire drawing is a mechanical processing method. Its principle is to use the ductility, toughness and tensile strength of metal materials. Through multi-pass die wheel traction and forced drawing, during the continuous pressing and stretching process, the cross-sectional area of ​​the metal material gradually decreases and the length gradually increases, thereby realizing the formation of metal wire. A Chinese patent with publication number CN114682637A discloses a drawing device for stainless steel wire processing, which mainly rolls the steel wire through a rotating pulling shaft. The steel wire is pulled in coordination with a rotating cleaning piece provided with a counterweight block to increase the inertia force of the rotating cleaning piece during rotation. When the rotating cleaning piece is hit by the impact force of the striking block, it will make a circular motion along the slide rails supporting the rotating ring and the supporting rotating plate. At this time, the iron oxide or lime particles piled on the side of the rubber blocking piece will be cleaned away.

[0003] In the above technical scheme, although the metal debris and lubricant in the die hole can be cleaned by pulling the shaft roll, cleaning sheet, lubricant and counterweight block to ensure the reduction of defects such as cracks, the counterweight block itself has a certain weight, and the deflection force will be difficult to control during rotation, resulting in errors when the circular motion is used to clean the side oxide scale or lime particles and other positions that need to be cleaned.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Combination Figure 1 and Figure 2As shown, a stainless steel wire drawing device described in an embodiment of the present invention comprises a base 1, a support roller 2, a rotating drum 3, and a rotating drum 4 for supporting the steel wire are connected to the top of the base 1, a wire drawing powder box 5 is fixedly connected to the top of the base 1, and since the bottom ends of the rotating drum 1 3 and the rotating drum 2 4 are respectively installed with direct drive motors, and the rotating rods of the rotating drum 1 3 and the rotating rods of the rotating drum 2 4 are connected to the output ends of the direct drive motors, a box body 6 is fixedly connected to the side of the wire drawing powder box 5, a mold 7 is fixedly connected to the inside of the box body 6, a mold hole that is squeezed with the diameter of the steel wire is opened in the middle of the mold 7, and a debris cleaning device is installed in the box body 6. The debris cleaning component includes a wiping strip 60, which drives the wiping strip 60 to reciprocate in the die hole to dredge it. A notch is provided on the front end surface above the wire drawing powder box 5. A sleeve 51 for limiting the position of the steel wire is rotatably connected in the notch of the wire drawing powder box 5. The outer surface of the sleeve 51 is provided with evenly distributed through holes. When working, the equipment is first applied to the steel wire drawing processing plant. When the stainless steel wire is drawn, the inner wall of the die hole of the mold 7 contacts the steel wire to limit the position of the steel wire. After the steel wire is drawn and the diameter is changed, the surface of the steel wire The metal debris on the surface will remain in the die hole, which may easily affect the drawing of the steel wire. Using the embodiment of the present invention, the steel wire is first descaled. After the descaling is removed, the steel wire is initially wound around the outside of the support roller 2 by default to form a steel wire coil, and then wire drawing powder is added to the outer surface of the steel wire. Finally, the steel wire wound around the outside of the support roller 2 is wound around the drum 2 4 through the drum 1 3, and the direct drive motor is driven. The drum 2 4 is powered on and rotates. The drum 2 4 rotates to pull the steel wire, and the steel wire passes through the sleeve 51 in the wire drawing powder box 5. The steel wire is lubricated with wire drawing powder and passes through the abrasive 7 Due to the squeezing of the mold 7, the diameter of the steel wire becomes smaller and reaches the desired diameter. During the transportation to the mold 7, the debris cleaning component is powered on to drive the debris cleaning component to work. The debris cleaning component generates a circular motion. Under the swing amplitude of the circular motion force, the wiping strip 60 is impacted and squeezed toward the die hole position of the mold 7. The wiping strip 60 continuously squeezes and dredges the metal debris on the inner wall of the die hole, thereby automatically cleaning the metal debris on the inner wall of the die hole, solving the problem of internal metal debris clogging, and achieving the effect of cleaning the inner wall of the die hole. Finally, the metal debris falls and is recovered under the box 6. Combination Figure 3 to Figure 4As shown, the debris cleaning assembly includes a chuck 61 slidably connected to the top of the box body 6, the chuck 61 is rotatably connected to the side of the grinding tool 7 with a central axis 62, the central axis 62 is externally connected with a folding strip 63, the folding strip 63 is installed with an air bag on the side of the chuck 61, the bottom end of the folding strip 63 is fixedly connected to a pressure plate 64, the bottom end of the pressure plate 64 is rotatably connected to an arc strip 65, a through rod 66 is transferred to the inner cavity of the arc strip 65, a thin strip 67 is fixedly connected to the front end below the arc strip 65, a torsion plate 68 is fixedly connected to the end of the through rod 66 away from the arc strip 65, a rotating shaft 69 is fixedly connected to the center of the side of the torsion plate 68 away from the through rod 66, the front side of the pressure plate 64 is fixedly connected to the wiping strip 60, and a wire cleaning assembly is installed on the outside of the thin strip 67. The wire cleaning assembly is used to clean the outer periphery of the steel wire. Cleaning; A through groove that slides with the chuck 61 is provided on the top of the box body 6, and the middle part of the pressure plate 64 is rotatably connected to the arc bar 65. A servo motor is externally connected to one end of the rotating shaft 69, and the rotating shaft 69 is connected to the output end of the servo motor. The wiping strip 60 is made of rubber; a sliding groove corresponding to the outer periphery of the through rod 66 is provided inside the arc bar 65, and a rod is installed between the pressure plate 64 and the arc bar 65; during operation, during the process of drawing the steel wire, the outer skin of the steel wire is easily fallen off due to the effect of drawing, and falls on the inner wall of the die hole of the mold 7, causing pollution and blockage to the inner wall of the die hole. When using the embodiment of the present invention, the servo motor is powered on to drive the rotating shaft 69 to move, and the rotating shaft 69 rotates to drive the torsion plate 68 to move. , the torsion plate 68 rotates counterclockwise, and the torsion plate 68 gradually links the through rod 66 to work. When the through rod 66 rotates, it gradually moves in a circle along the inner wall of the arc strip 65. When the through rod 66 rotates to the end above the sliding groove of the arc strip 65, it will drag it. The arc strip 65 is pushed to the left after the end is pushed by the through rod 66. The chuck 61 and the middle axis 62 move synchronously. The chuck 61 slides to the left along the inner wall of the box body 6 in the horizontal direction. The middle axis 62 and the chuck 61 form a folded shape. With the continuous movement of the through rod 66, when the through rod 66 rotates to the bottom, the through rod 66 pushes the end of the sliding groove of the arc strip 65 at the bottom. At this time, the arc strip 65 is driven to the right as a whole, and the chuck 61 gradually slides to the right, and the folding strip 63 changes its shape. The folding strip 63 and the chuck 61 change from a folded state when moving to the left to an unfolded state, and the chuck 61 drives the pressure plate 64 to work, and the pressure plate 64 pushes the wiping strip 60 to move to the right in the horizontal direction, and the wiping strip 60 is inserted into the die hole of the mold 7, so that the equipment has the function of rapid unblocking and the function of automatically removing metal debris on the inner wall of the die hole, thereby improving the internal cleaning effect and preventing cracks from appearing due to subsequent use of drawing; it should be noted that; the die hole of the mold 7 is a rectangular shape, and the size of the die hole can accommodate the steel wire and the wiping strip 60. After the movement, the wiping strip 60 is inserted into the inside of the die hole and is located on the bottom wall of the die hole. After the movement, the wiping strip 60 occupies the space inside the die hole and will not hinder the normal passage of the steel wire through the die hole.

[0022] When the steel wire is displaced, it passes through the wire drawing powder box 5. Since the wire drawing powder combines with the steel wire to reduce the friction coefficient, it lubricates the steel wire and prevents the steel wire from breaking due to drying during the drawing process. The wire drawing powder needs to be applied to the outside of the steel wire and added from the through hole on the outer surface of the sleeve 51. The wire drawing powder remains at the bottom of the inner wall of the sleeve 51. Although the passing steel wire can be coated with the wire drawing powder, the part where the wire drawing powder is coated on the steel wire is not uniform enough, and it is difficult to ensure complete contact between the steel wire and the wire drawing powder. When adjustment is needed, the chuck 61 is dragged to the left by the arc bar 65, the chuck 61 and the folding bar 63 form a folded shape, and the chuck 61 and the folding bar 63 form a tendency to fit when folded, and the air bag of the folding bar 63 is squeezed to discharge the gas. , the gas is blown in the direction close to the sleeve 51, and the wind enters from the through holes on the outer surface of the sleeve 51. The state of the wire drawing powder is changed by the blowing, and the wire drawing powder diffuses from the initial position at the bottom of the inner wall of the sleeve 51 toward the steel wire and is coated on the outer surface of the steel wire. Finally, when the steel wire passes through the sleeve 51, the wire drawing powder diffused to the surroundings adheres to the outside of the steel wire, thereby improving the lubrication degree of the steel wire. It should be noted that the force of the wire drawing powder diffusing to the surroundings after being blown is relatively small, and it can only be turned over inside the sleeve 51. There will be no phenomenon of floating around through the through holes, and the impact caused can be ignored. After the gas is discharged, the airbag is provided with an air inlet and an exhaust hole, and the air inlet installed on the airbag will re-intake air to complete the reset.

[0023] Combination Figures 7 to 9As shown, the cleaning assembly includes a twisting piece 671 installed on the outside of the thin strip 67, a lifting rod 672 is fixedly connected to the top of the twisting piece 671, a shell 673 is inserted into the end of the lifting rod 672, a round rod 674 is fixedly connected to the inner cavity of the lifting rod 672, two friction plates 675 are arranged above the round rod 674, and a positioning piece 676 is fixedly connected to the outer side of the top of the two friction plates 675. A clamping block 677 is connected to the outer surface of the lifting rod 672, and the clamping block 677 is located below the shell 673; a positioning groove and a round hole corresponding to the positioning piece 676 are opened inside the shell 673. The top of the lifting rod 672 passes through the interior of the shell 673, and the circular hole of the shell 673 is in the same straight line with the height of the sleeve 51; the interior of the shell 673 is hollow, the block 677 is fixedly connected to the wire drawing powder box 5, and the twisting piece 671 slides with the thin strip 67; when working, during the transportation process, although the outer surface of the steel wire is coated with wire drawing powder to complete the pretreatment, in order to facilitate the direct use in the subsequent secondary processing, the outer surface of the steel wire still needs to be thoroughly cleaned again. Using the embodiment of the present invention, the arc strip 65 is rotated and squeezed by the through rod 66 for transportation During the movement, the arc strip 65 moves toward the direction close to the torsion plate 671 under the action of the rotation force, and the arc strip 65 drives the thin strip 67 to move synchronously. The thin strip 67 squeezes the torsion plate 671 to work, and the inclined surface of the torsion plate 671 itself is rubbed. The inclined surface of the torsion plate 671 moves upward after being rubbed and squeezed. The torsion plate 671 pushes the lifting rod 672 to work, and the lifting rod 672 moves upward through the block 677. The lifting rod 672 drives the round rod 674 to move synchronously upward, and the round rod 674 drives the friction plate 675 to move upward. After the friction plate 675 is displaced, it gradually presses against the shell The inner wall of 673 slides, and the sleeve 51 is squeezed by the friction plate 675. When the friction plate 675 slides to the round hole of the shell 673, the positioning piece 676 loses its mortgage force and is inserted into the positioning groove of the shell 673. At this time, the two friction plates 675 open from the initial closed state to the expanded state. The reserved gap after the two friction plates 675 are expanded is adapted to the diameter of the steel wire, so that the steel wire is wiped by the friction plate 675 when passing through. Since the friction plate 675 can only accommodate the passage of the steel wire, the wire drawing powder is scraped off at this time, and automatic cleaning is completed at the same time, thereby improving work efficiency.

[0024] Combination Figures 5 and 6As shown, a push assembly is installed on the side of the drawing powder box 5, and the push assembly is used to adjust the front and rear distance of the sleeve 51. The push assembly includes a telescopic cylinder 81 installed on the side of the drawing powder box 5, and an induction switch is arranged in the telescopic cylinder 81. An electric telescopic rod 82 is connected to the inner cavity of the telescopic cylinder 81. A push piece 83 is fixedly connected to the top of the electric telescopic rod 82. The end of the push piece 83 away from the electric telescopic rod 82 is fixedly connected to a ratchet bar 84. The lower surface of the ratchet bar 84 is meshed and connected to a limited tooth plate 85; the outer surface of the sleeve 51 is provided with a limit tooth plate 85 that is connected to the ratchet bar 8 4 corresponding teeth, the limiting tooth plate 85 is located below the teeth of the sleeve 51, and the limiting tooth plate 85 is misaligned with the teeth of the sleeve 51; the external transmission of the rotating shaft 69 is connected with the belt 8, and the top of the belt 8 is connected with the telescopic cylinder 81; when working, the rotating drum 4 draws the steel wire, and when the steel wire moves toward the direction of the mold 7, the steel wire will have a deflection problem, which affects the drawing effect. The limiting of the steel wire can save a lot of time, and the steel wire is located inside the sleeve 51, which is inconvenient to adjust. The present invention is used In the embodiment, the rotation of the rotating shaft 69 drives the belt 8 to move synchronously, and the belt 8 is linked to the rotation of the telescopic cylinder 81. When the telescopic cylinder 81 rotates, the internal inductive switch receives the electrical signal to be processed, and the inductive switch starts to work. The telescopic cylinder 81 rotates to push out the electric telescopic rod 82, and the electric telescopic rod 82 moves according to the threshold value preset by the program. When it moves to the appropriate position, the inductive switch in the telescopic cylinder 81 stops, and the electric telescopic rod 82 moves to squeeze the push piece 83, and the push piece 83 moves to squeeze the ratchet bar 84, and the ratchet bar 84 gradually moves. The sleeve 51 is meshed with the sleeve 51, and after the sleeve 51 rotates, it is squeezed with the limit tooth plate 85. The sleeve 51 and the limit tooth plate 85 are meshed, and the limit tooth plate 85 is displaced in the opposite direction, thereby changing the initial position of the sleeve 51. The steel wire inside the sleeve 51 is therefore synchronously adjusted, and the deflected steel wire is adjusted. When the electric telescopic rod 82 is extended to the specified position, the deviation correction of the sleeve 51 is completed. It has the function of preventing the steel wire from deviating by utilizing the clamping force between the teeth, so as to facilitate adjustment and ensure the normal pulling of the steel wire.

[0025] Working principle: During the wire drawing process, the outer skin of the wire is easily peeled off due to the effect of drawing, and falls on the inner wall of the die hole of the mold 7, causing pollution and blockage to the inner wall of the die hole. Using the embodiment of the present invention, the servo motor is energized to drive the shaft 69 to move, and the rotation of the shaft 69 drives the torsion plate 68 to move. The torsion plate 68 rotates counterclockwise, and the torsion plate 68 gradually links the through rod 66 to work. When the through rod 66 rotates, it gradually moves along the inner wall of the arc strip 65 in a circular motion. When the through rod 66 rotates to the end above the sliding groove of the arc strip 65, it will be dragged. The arc strip 65 is moved to the left after being pushed by the through rod 66. The chuck 61 and the middle shaft 62 move synchronously. The chuck 61 slides horizontally to the left along the inner wall of the box body 6, and the middle shaft 62 and the chuck 61 form a folded shape. As the through rod 66 continues to move, when the through rod 66 rotates to the bottom in a circular motion, The through rod 66 pushes the lower end of the sliding groove of the arc bar 65. At this time, the arc bar 65 is driven to the right as a whole, and the chuck 61 gradually slides to the right, and the folding strip 63 changes its shape. The folding strip 63 and the chuck 61 change from a folded state when moving to the left to an unfolded state. The chuck 61 drives the pressure plate 64 to work, and the pressure plate 64 pushes the wiping strip 60 to move to the right in the horizontal direction. The wiping strip 60 is inserted into the die hole of the mold 7, so that the equipment has the function of rapid dredging and the function of automatically removing metal debris on the inner wall of the die hole, thereby improving the internal cleaning effect and preventing cracks from appearing due to subsequent use of drawing. It should be noted that the die hole of the mold 7 is a rectangular parallelepiped, and the size of the die hole can accommodate the steel wire and the wiping strip 60. After the movement, the wiping strip 60 is inserted into the inside of the die hole and is located on the bottom wall of the die hole. After the movement, the wiping strip 60 occupies the space inside the die hole and will not hinder the normal passage of the steel wire through the die hole.

[0026] When the steel wire is displaced, it passes through the wire drawing powder box 5. Since the wire drawing powder combines with the steel wire to reduce the friction coefficient, it lubricates the steel wire and prevents the steel wire from breaking due to drying during the drawing process. The wire drawing powder needs to be applied to the outside of the steel wire and added from the through hole on the outer surface of the sleeve 51. The wire drawing powder remains at the bottom of the inner wall of the sleeve 51. Although the passing steel wire can be coated with the wire drawing powder, the part where the wire drawing powder is coated on the steel wire is not uniform enough, and it is difficult to ensure complete contact between the steel wire and the wire drawing powder. When adjustment is needed, the chuck 61 is dragged to the left by the arc bar 65, the chuck 61 and the folding bar 63 form a folded shape, and the chuck 61 and the folding bar 63 form a tendency to fit when folded, and the air bag of the folding bar 63 is squeezed to discharge the gas. , the gas is blown in the direction close to the sleeve 51, and the wind enters from the through hole on the outer surface of the sleeve 51. The state of the wire drawing powder is changed by the blowing, and the wire drawing powder diffuses from the initial position at the bottom of the inner wall of the sleeve 51 toward the steel wire and is coated on the outer surface of the steel wire, so that when the steel wire passes through the sleeve 51, the wire drawing powder diffused to the surroundings adheres to the outside of the steel wire, thereby improving the lubrication degree of the steel wire. It should be noted that the force of the wire drawing powder diffusing to the surroundings after being blown is relatively small, and it can only be turned over inside the sleeve 51. There will be no phenomenon of floating to the surroundings through the through hole, and the impact caused can be ignored. After the gas is discharged, the airbag is provided with an air inlet and an exhaust hole, and the air inlet installed on the airbag will re-intake air to complete the reset. During the transportation process, although the outer surface of the steel wire is coated with wire drawing powder to complete the pre-treatment, in order to facilitate direct use in the subsequent secondary processing, it is still necessary to thoroughly clean the outer surface of the steel wire again. Using the embodiment of the present invention, during the process of the arc bar 65 being rotated and extruded by the through rod 66, the arc bar 65 moves in the direction close to the twisting piece 671 under the action of the rotational force, and the arc bar 65 drives the thin strip 67 to move synchronously. The thin strip 67 squeezes the twisting piece 671 to work, and the inclined surface of the twisting piece 671 itself is rubbed. The inclined surface of the twisting piece 671 moves upward after being rubbed and squeezed, and the twisting piece 671 pushes the lifting rod 672 to work. The lifting rod 672 moves upward through the block 677, and the lifting rod 672 moves upward. The round rod 674 is driven to move synchronously, and the round rod 674 drives the friction plate 675 to move upward. After the friction plate 675 is displaced, it gradually slides against the inner wall of the shell 673. The sleeve 51 is squeezed by the friction plate 675 at this time. When the friction plate 675 slides to the round hole of the shell 673, the positioning piece 676 loses its mortgage force and is inserted into the positioning groove of the shell 673. At this time, the two friction plates 675 are opened, from the initial closed state to the expanded state. The reserved gap between the two friction plates 675 after the expansion is adapted to the diameter of the steel wire, so that the steel wire is wiped by the friction plate 675 when passing through. Since the friction plate 675 can only accommodate the passage of the steel wire, the wire drawing powder is scraped off at this time, and automatic cleaning is completed at the same time, thereby improving work efficiency.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention.
