Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire drawing, more particularly, it relates to an alloy wire lubricating and cooling device for wire drawing production. BACKGROUND

[0002] The metal wire drawing (wire drawing) process is the core technology of metal wire plastic processing, which realizes the processing process of reducing the diameter of the wire, optimizing the cross-sectional shape and improving the mechanical properties by driving the metal wire through the die hole with a specific aperture by external force.

[0003] Firstly, the wire enters the drawing machine and is wound around and passes through the die hole under the traction of the capstan, and if a large reduction is required, multiple passes of drawing are required. During the drawing process, the surface of the steel wire and the inner hole wall of the die will produce severe friction, and the temperature of the steel wire and the die will rise sharply, so the oil nozzle continuously sprays drawing oil to the surface of the two tower wheels and the drawing die, thereby cooling and lubricating the drawn wire.

[0004] At present, because the drawing oil is sprayed to the position of the drawing die through the oil nozzle, and the drawing oil accumulates at the position of the drawing die, and the drawing oil can only be discharged through the groove at the wire passing position of the die holder, the impact force of the steel wire when passing through the drawing die will splash the accumulated drawing oil, and the accumulated drawing oil is easy to retain metal chips, die powder and other impurities. These impurities will splash the oil liquid and then fall again on the position of the drawing die, not only causing the accumulation of impurities at the position of the die hole of the drawing die, but also repeatedly washing the gap between the die and the steel wire, on the one hand, scratching the surface of the steel wire and damaging the oil film attachment basis, on the other hand, the impurity particles will be embedded in the oil film, become abrasive particles, accelerate the rupture of the oil film, and ultimately affect the lubricating effect of the drawing oil.

[0046] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0049] Please refer to Figures 1-3, two tower wheels 16 rotate inside the drawing box 13, two rotating rods 15 rotate symmetrically inside the drawing box 13, the two tower wheels 16 are correspondingly arranged with the two rotating rods 15, the tower wheel 16 is sleeved and installed on the outer side wall of the corresponding rotating rod 15, two driving motors 17 are symmetrically installed on the side of the drawing box 13 away from the tower wheel 16, the output ends of the two driving motors 17 extend to the inside of the drawing box 13 and are respectively connected with the two rotating rods 15, the driving motor 17 is used for driving the corresponding rotating rod 15 and the tower wheel 16 to rotate, the two tower wheels 16 cooperate to guide the metal wire entering the inside of the drawing box 13, so that the metal wire can complete repeated rotation in the drawing box 13, and then is output through the exit die 14. Specifically, when the metal wire enters the drawing box 13 through the entrance die 12, it first passes through the wire groove at the smallest diameter position of the tower wheel 16, and is repeatedly rotated and wound through the two tower wheels 16, and when output, the metal wire passes through the wire groove at the largest diameter position of the tower wheel 16 and is output from the exit die 14.

[0050] Referring to Figures 1-3 , the lubricating and cooling assembly 2 and the die carrier assembly 3 are installed inside the drawing box 13, and the die carrier assembly 3 is located between the two tower wheels 16, the die carrier assembly 3 is used for drawing and reducing the diameter of the metal wire that repeatedly rotates, that is, when the metal wire passes above the two tower wheels 16, the metal wire first passes through the die carrier assembly 3 after passing through the first tower wheel 16, then reaches above the second tower wheel 16, and is wound again after passing below the two tower wheels 16, and reaches above the tower wheel 16 again, and passes through the die carrier assembly 3 again, and reciprocates in this way.

[0051] During the drawing process of the wire, the surface of the wire and the inner hole wall of the drawing die 35 will produce intense friction, and the temperature of the wire and the drawing die 35 will rise sharply, therefore the lubricating and cooling assembly 2 continuously sprays drawing oil to the surfaces of the two tower wheels 16 and the drawing die 35, thereby cooling and lubricating the metal wire wound on the tower wheel 16 and passing through the die carrier assembly 3.

[0052] Referring to Figures 1-3 , the die carrier assembly 3 includes the die seat mechanism 34 and a plurality of drawing dies 35 arranged on the top of the die seat mechanism 34, when the metal wire reaches the position of the die carrier assembly 3, the metal wire passes through the first drawing die 35 arranged on the top of the die seat mechanism 34, then passes through the second drawing die 35 again after winding a circle around the two tower wheels 16, and reciprocates in this way, so as to pass through the last drawing die 35 and be output through the exit die 14 after passing through the top of the corresponding tower wheel 16 between the drawing die 35 and the exit die 14, the metal wire completes the diameter reduction after passing through the plurality of drawing dies 35.

[0053] Referring to Figures 1-3The lubricating and cooling assembly 2 is located above the tower wheel 16, and the lubricating and cooling assembly 2 comprises an oil supply main pipe 21 located above the tower wheel 16, one end of the oil supply main pipe 21 extending to the outside of the drawing box 13, and three oil supply branch pipes 22 being in communication with the outer side wall of the oil supply main pipe 21, the end portions of the three oil supply branch pipes 22 being in communication with oil nozzles 23, and the three oil nozzles 23 being correspondingly arranged at the two tower wheels 16 and the die carrier assembly 3, respectively. During the drawing process, the oil supply main pipe 21 is in communication with an external oil supply device, which can be an oil supply pump, and the drawing oil flows into the three oil supply branch pipes 22 and the corresponding oil nozzles 23 through the oil supply main pipe 21, and is discharged to the plurality of drawing dies 35 above the die seat mechanism 34 and the top portions of the two tower wheels 16 through the three oil nozzles 23, so as to cool and lubricate the metal wire wound on the tower wheel 16 and passing through the die carrier assembly 3.

[0054] In the second embodiment, the drawing oil is sprayed to the position of the drawing die 35 through the oil nozzle 23, and the drawing oil is accumulated at the position of the drawing die 35, and can only be discharged through the groove at the wire passing position of the die seat mechanism 34. The impact force of the steel wire when passing through the drawing die 35 can drive the accumulated drawing oil to splash, and the accumulated drawing oil is easy to retain metal chips, die powder and other impurities. These impurities can splash again after the oil liquid splashes, and then fall to the position of the drawing die 35, which not only causes the accumulation of impurities at the position of the drawing die 35, but also causes the impurities to repeatedly wash the gap between the drawing die 35 and the steel wire, which on the one hand scratches the surface of the steel wire and damages the oil film attachment basis, and on the other hand, the impurity particles can be embedded in the oil film to become abrasive particles, accelerate the rupture of the oil film, and finally affect the lubricating effect of the drawing oil.

[0055] Referring to Figures 6-10 Therefore, the die seat mechanism 34 is further improved, the die seat mechanism 34 comprises a wedge block 341 and a protruding block 342 installed on the top of the wedge block 341, the top of the wedge block 341 is provided with two limiting plates 343, the two sides of the protruding block 342 and the two limiting plates 343 form an inclined flow groove, the top of the protruding block 342 is provided with a plurality of clamping seats 344, and the top of the protruding block 342 is provided with a partition plate 348, the partition plate 348 divides each clamping seat 344, the plurality of drawing dies 35 are divided into two groups and are arranged in sequence in a staggered manner on the two sides of the partition plate 348, and the drawing dies 35 are arranged in the clamping seats 344 on one side of the partition plate 348, and the side walls of the two limiting plates 343 and the partition plate 348 are equally provided with guide grooves corresponding to the drawing dies 35.

[0056] Specifically, the top of the convex block 342 has the same inclination angle as the top of the wedge block 341, and a plurality of clamping seats 344 are arranged along the inclination angle of the top of the convex block 342, the clamping seats 344 are used to place the drawing dies 35, and the partition plate 348 divides each clamping seat 344 into left and right parts, when the left part of the first clamping seat 344 places the drawing die 35, the right part of the second clamping seat 344 places the corresponding drawing die 35, and so on, so that the plurality of drawing dies 35 are staggered by the partition plate 348.

[0057] The wire is arranged in the plurality of drawing dies 35 through the repeated winding of the two capstans 16, when the oil nozzle 23 corresponding to the capstan 16 sprays drawing oil, the drawing oil falls on the top of the corresponding capstan 16, thereby lubricating and cooling the wire on the capstan 16, and flushing the impurities on the capstan 16, and then the drawing oil falls into the inside of the drawing tank 13 and is collected, and when the oil nozzle 23 corresponding to the die seat mechanism 34 sprays drawing oil, the drawing oil falls on the top of the wedge block 341 and is blocked by the two limiting plates 343, the drawing oil is accumulated on the top of the wedge block 341, thereby lubricating and cooling the wire passing through the drawing die 35, and flushing the impurities accumulated on the top of the wedge block 341, the flushed impurities flow into the inclined flow groove and flow away along the inclination direction of the inclined flow groove, thereby reducing the accumulation and splashing of the impurities, and reducing the degree of damage to the oil film on the surface of the wire.

[0058] Referring to Figures 6-10 , the die frame assembly 3 further comprises a mounting plate 31 mounted on the side wall of the drawing tank 13 and two connecting plates 32 symmetrically connected to the side wall of the mounting plate 31, two link plates 345 are symmetrically connected to the side of the wedge block 341 close to the mounting plate 31, the two link plates 345 are inserted between the two connecting plates 32, two long holes 36 are arranged on the opposite side of the two link plates 345, the locking bolts 33 are inserted on the side of the two connecting plates 32 away from each other, the locking bolts 33 are inserted into the corresponding long holes 36 and locked by nuts, the wedge block 341 is connected by the link plates 345 and the connecting plates 32, and is locked by nuts, and a gap is provided between the wedge block 341 and the mounting plate 31, when the drawing oil mixed with impurities flows along the inclined flow groove, the drawing oil and impurities directly fall through the gap and flow into the inside of the drawing tank 13.

[0059] Referring to Figures 6-10The reinforcing plate 346 is connected with the side wall of the wedge block 341, and the height of the reinforcing plate 346 is higher than that of the side wall of the wedge block 341. Two through grooves 347 are symmetrically arranged on the side wall of the reinforcing plate 346, and the two through grooves 347 are arranged corresponding to the two inclined flow grooves. The reinforcing plate 346 connects the two connecting plates 345, and the two through grooves 347 arranged on the reinforcing plate 346 are used to cooperate with the corresponding inclined flow grooves, so that the drawing oil mixed with impurities can be smoothly discharged.

[0060] In the third embodiment, when the metal wire enters the inside of the drawing box 13 through the inlet die 12, due to the defects of the initial form of the metal wire, that is, the bending of the metal wire when the wire is unwound, the metal wire cannot be completely straightened after passing through the tower wheel 16, and the metal wire will vibrate during conveying. When the metal wire is conveyed to the first drawing die 35, the metal wire is not coaxial with the die hole of the drawing die 35, and neutral deviation occurs. The central axis of the drawing die 35 is not coincident with the tangent direction of the metal wire outlet of the tower wheel 16, and the steel wire has a deflection angle when entering the drawing die 35, and is subjected to lateral extrusion force. When the steel wire passes through the second drawing die 35, the vibration still exists. With the increase of the number of drawing dies 35 passed, the vibration of the steel wire will be relieved.

[0061] However, during the early drawing process, the steel wire needs to pass through the die hole deformation zone of the drawing die 35 coaxially. If the steel wire enters the drawing die 35 in a vibrating state, the drawn steel wire is not a regular circle, but an ellipse or a polygon. Due to uneven stress, the reduction amount of one side of the steel wire is large, and the reduction amount of the other side is small, resulting in serious diameter fluctuation along the entire length. Dry grinding occurs at the position where the reduction amount of the steel wire is large and the die hole of the drawing die 35. Even if the steel wire is lubricated by spraying drawing oil, the problem cannot be solved.

[0062] When the steel wire is in a dry grinding state with the drawing die 35, impurities will accumulate at the position of the die hole of the drawing die 35. The accumulation of impurities will increase the resistance when the steel wire passes through the drawing die 35. If the drawing continues under the condition of large resistance, the steel wire will be broken due to failure. By arranging the inclined flow grooves and the flow direction of the inclined flow grooves, the amount of impurity accumulation is reduced, and the drawing resistance is reduced.

[0063] However, without the accumulation and blockage of impurities, due to the fact that the reduction amount of one side of the steel wire is large and the reduction amount of the other side is small, the cross section of the steel wire is no longer a regular circle, but an ellipse. The metal on the side with large reduction amount is compressed more, and flows and accumulates to the other side with small reduction amount. Asymmetric residual stress is generated in the cross section. The residual tensile stress on the side with large reduction amount is large. During the continuous drawing process in the vibrating state, the position with large tensile stress becomes the crack initiation point, which causes the failure of the steel wire during the drawing process. Once the failure occurs, it will affect the subsequent drawing process, so that the steel wire cannot be drawn to the required diameter.

[0064] For this adjustment for the vibration of the steel wire, the drawing oil can form an oil film on the surface of the steel wire, the steel wire enters the drawing die 35 coaxially in a lubricated and cooled state, thereby reducing the eccentric wear and preventing the failure of the steel wire, so that the steel wire can be drawn and output completely.

[0065] Referring to Figures 2-5 , the inside of the drawing box 13 is provided with a limiting assembly 4, which is located between the two capstans 16 and is used to limit the steel wire to reduce vibration. The specific structure of the limiting assembly 4 is as follows:

[0066] Referring to Figures 2-5 , the limiting assembly 4 includes a fixed plate 41 installed on the inner wall of the drawing box 13, which is located above the die carrier assembly 3. The top of the side wall of the fixed plate 41 is provided with a fixed block 42, the top of the fixed block 42 is rotatably connected with a lead screw 43, the bottom end of the lead screw 43 penetrates through the fixed block 42 and is threadedly connected with a moving plate 45. By rotating the lead screw 43, the moving plate 45 can be lifted in the height direction. In addition, in order to avoid the moving plate 45 from rotating with the lead screw 43, two guide rails 44 are symmetrically installed on the inner side wall of the drawing box 13. The moving plate 45 is slidably connected to one side of the two guide rails 44 and slides along the extension direction of the guide rails 44. The side of the moving plate 45 away from the guide rails 44 is rotatably connected with two sets of limiting wheel mechanisms 46. The moving plate 45 moves synchronously with the two sets of limiting wheel mechanisms 46. During the preliminary winding process, the two sets of limiting wheel mechanisms 46 are lifted to facilitate the winding of the steel wire on the capstan 16. When the winding is completed and the drawing is ready, the height of the moving plate 45 is adjusted so that the two sets of limiting wheel mechanisms 46 are attached to the top of the corresponding capstan 16. The limiting wheel mechanisms 46 are used to assist in limiting the steel wire during drawing, so that the steel wire can reduce vibration. During the preliminary installation of the drawing die 35, the worker adjusts the drawing die 35 to the same position as the corresponding line groove of the capstan 16 to ensure that the steel wire can smoothly enter the drawing die 35.

[0067] Referring to Figures 2-5 , each of the two sets of limiting wheel mechanisms 46 includes a rotating shaft 461 rotatably connected to the side wall of the moving plate 45. A plurality of positioning rings 462 are equidistantly installed on the outer side wall of the rotating shaft 461. The diameters of the plurality of positioning rings 462 gradually increase in the direction close to the inner side wall of the drawing box 13. A limiting ring 463 is connected between two adjacent positioning rings 462. When the positioning ring 462 is attached to the protruding position of the rotating rod 15, the limiting ring 463 is inserted between the adjacent protruding positions of the rotating rod 15. The rotating shaft 461 is rotatably connected to the side wall of the moving plate 45 through a bearing. Since the line grooves on both sides of the capstan 16 are provided with protruding positions, which can be blocking rings, the steel wire is blocked so that the steel wire can be conveyed in the corresponding line groove.

[0068] When the limiting wheel mechanism 46 is pressed on the corresponding tower wheel 16, the positioning ring 462 first fits the protruding position (blocking ring) outside the tower wheel 16, and the limiting ring 463 is deeply inserted into the corresponding wire slot and fits the steel wire in the wire slot. Specifically, the steel wire is limited by the cooperation of the limiting ring 463 and the wire slot of the tower wheel 16, and the tower wheel 16 cooperates with the limiting ring 463 to transport the steel wire when rotating. The steel wire does not vibrate during the transportation process, and then the steel wire reaches the position of the drawing die 35 through the guide groove on the limiting plate 343. The steel wire completes a drawing after passing through the drawing die 35, and then reaches the position of another set of limiting wheel mechanism 46 and tower wheel 16 for limiting, and then is limited again after being guided around by two tower wheels 16. Repeat the above process.

[0069] Referring to Figures 2-5 The outer wall of the rotating shaft 461 is sleeved with a driven wheel 47, and the outer wall of the driven wheel 47 and the outer wall of the driving wheel 48 are in abutment. When the limiting wheel mechanism 46 cooperates with the corresponding tower wheel 16 to limit the steel wire, the driven wheel 47 is inserted and extruded with the driving wheel 48 when the driven wheel 47 moves downward with the rotating shaft 461. The outer walls of the driven wheel 47 and the driving wheel 48 are made of rubber material, thereby increasing the friction. When the driving wheel 48 rotates with the rotating shaft 15, the driven wheel 47 rotates synchronously through the friction between the driving wheel 48 and the driven wheel 47. The driven wheel 47 drives the rotating shaft 461, the positioning ring 462 and the limiting ring 463 to rotate synchronously. The rotating direction of the limiting wheel mechanism 46 is opposite to that of the corresponding tower wheel 16, so that the limiting wheel mechanism 46 and the corresponding tower wheel 16 cooperate to transport the steel wire.

[0070] In addition, the positioning ring 462 and the limiting ring 463 can be adapted, combined and installed according to the shape and diameter of the tower wheel 16, thereby further improving the versatility of the limiting wheel mechanism 46.

[0071] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.
