Description

Technical Field

[0001] The invention belongs to the technical field of metal wires, and in particular relates to a precision drawing machine. Background Art

[0002] The fine drawing machine is a machine that processes raw materials into standard diameters that meet the requirements through wire drawing. It is mainly driven by an electric motor. The fine drawing machine is a plastic processing method that deforms metal raw materials through the die hole of a fine drawing die. During the fine drawing process, the raw materials undergo plastic deformation in the fine drawing die. After passing through the fine drawing die, the cross-sectional shape and size of the raw materials are the same as those at the die hole outlet of the fine drawing die. It is widely used in the fine drawing of wires and pipes.

[0003] Metal wires need to undergo pickling, annealing, wire drawing and other treatments before processing. The purpose of wire drawing is to cold-draw the wire to the required wire diameter. It can generally be divided into two stages: rough drawing and fine drawing. First, a continuous wire drawing machine is used to roughly draw the wire to a certain wire diameter, and then annealing is performed to eliminate the processing stress generated by rough drawing. Subsequently, fine drawing is performed to reach the required wire diameter to ensure that the surface reduction rate of fine drawing is less than 15%.

[0004] In the prior art, when the fine drawing machine finely draws the wire to the required wire diameter, it usually unwinds the metal wire through an unwinding mechanism. The metal wire needs to be lubricated by a lubricating mechanism before reaching the fine drawing model block, and then the pulling mechanism pulls the metal wire from the fine drawing model block, and the metal wire that has been finely drawn to the required wire diameter is reeled by the reeling mechanism, and then the fine drawing process of the metal wire is completed. However, it is found in the actual application process that it has the following obvious problems:

[0005] (1) When the metal wire is being finely drawn, it is easy for the metal wire to have insufficient tension when it is drawn through the unwinding mechanism, the pulling mechanism and the winding mechanism, resulting in uneven force on the metal wire during fine drawing. It is necessary to perform multiple reciprocating fine drawing to ensure the required surface reduction rate of the wire. The process is complicated and the efficiency of fine drawing of the metal wire is low;

[0006] (2) In the process of fine drawing of metal wire, insufficient tension force may easily lead to deviation of metal wire during drawing, which may cause the metal wire to be loose, knotted or unevenly wound at the winding mechanism, thereby reducing the efficiency of fine drawing and winding of metal wire;

[0007] (3) The metal wire needs to be completely lubricated before entering the fine drawing model block, which requires a large amount of lubricating oil. After the metal wire passes through the fine drawing model block, lubricating oil is likely to remain on its surface. Although the lubricating oil can improve the convenience of pulling and conveying the metal wire to a certain extent, the residual lubricating oil on the surface of the metal wire needs to be effectively removed before winding, and the residual trace lubricating oil must be evenly coated. The process is relatively complicated, and the lubricating oil remaining on the surface of the metal wire lacks effective collection and reuse, and the utilization rate of the lubricating oil is low, which greatly increases the processing cost of the metal wire during fine drawing.

[0008] Therefore, a fine drawing machine is needed to solve the problems in the prior art that when metal wire is finely drawn by the fine drawing machine, the wire pulling tension is insufficient and the removal of lubricating oil on the wire surface is inconvenient, resulting in low processing efficiency and greatly increased processing costs during fine drawing of the metal wire.

[0042] The pulling and conveying mechanism 6 includes two conveying rollers 61 distributed up and down and arranged on the outer side of the oil filling box 2. The two conveying rollers 61 are rotatably connected to the opposite surfaces of the two frames 1. The outer end of one of the frames 1 is provided with two transmission gears a62 coaxially fixed with the two conveying rollers 61, and the two transmission gears a62 are meshingly connected. The outer surfaces of the two conveying rollers 61 are provided with inwardly recessed guide grooves, which are adapted to the size of the metal wires that have been roughly drawn. The other side of the oil filling box 2 is provided with two pulling rollers 63 distributed up and down. The two pulling rollers 63 are rotatably connected to the opposite surfaces of the two frames 1. The outer side of one of the frames 1 is provided with two transmission gears b64 coaxially fixed with the two pulling rollers 63, and the two transmission gears b64 are meshingly connected. The outer surfaces of the two pulling rollers 63 are provided with guide rings coaxially fixed outwards, which are in close contact with the surface of the metal wire after the fine drawing treatment by the fine drawing model block 4, thereby realizing fine adjustment of the metal wire through its guide ring. Fine drawing, thereby further ensuring the fine drawing reduction rate of the metal wire, the outer ends of the conveying roller 61 and the pulling roller 63 located at the same height are coaxially fixed with a transmission pulley a65, and a transmission belt a66 is arranged between the outer surfaces of the two transmission pulleys a65. A traction motor 67 coaxially connected to the pulling roller 63 is arranged at the outer end of one of the frames 1. The conveying roller 61 and the pulling roller 63 are respectively driven by the meshing of the transmission gear a62 and the transmission gear b64, so that the two conveying rollers 61 and the two pulling rollers 63 are facing The metal wire is rotated at the center, and then the power provided by the traction motor 67 is matched with the transmission function of the drive pulley a65 and the drive belt a66, so as to perform double traction treatment on the metal wire before and after fine drawing, thereby ensuring the smoothness of the metal wire during traction and transportation, and through the contact effect between the conveying roller 61 and the pulling roller 63 and the surface of the metal wire, the tension of the metal wire before fine drawing is effectively guaranteed, and the metal wire is effectively prevented from being loosened or knotted during the subsequent winding process;

[0043] The winding mechanism 7 includes a winding shaft 71 detachably arranged at the ends of the two frames 1, and the outer surface of the winding shaft 71 is provided with a winding drum 72 corresponding to the fine drawing model block 4 one by one. The outer surface of one of the frames 1 is provided with a variable frequency winding motor 73 coaxially connected to the winding shaft 71, and the outer surface of the winding shaft 71 is provided with a convex strip, and the inner surface of the winding drum 72 is provided with a slide groove adapted to the convex strip, so that the radial direction of the winding drum 72 can be limited. Fasteners are provided at both ends of the winding drum 72 for limiting the axis of the winding drum 72. In the process of continuous winding by the variable frequency winding motor 73, the outer ring diameter of the metal wire on the winding drum 72 gradually increases. At this time, the power provided by the variable frequency winding motor 73 also increases accordingly. The winding drum 72 is preferably three, so that three groups of synchronous fine drawing can be performed on the metal wire, thereby improving the fine drawing processing and production efficiency of the metal wire to a certain extent.

[0044] The tensioning force adjusting mechanism 8 includes a guide roller 81 arranged outside the pulling roller 63, the guide roller 81 is rotatably connected with the opposite surfaces of the two frames 1, an arc groove 82 opened on the outer surface of the frame 1 is arranged above the guide roller 81, an adjusting roller 83 is arranged between the two arc grooves 82, a mounting plate 84 fixed to the opposite surfaces of the two frames 1 is arranged above the adjusting roller 83, a hydraulic cylinder 85 is fixed on the top surface of the mounting plate 84, and the driving end of the hydraulic cylinder 85 is fixed There is a U-shaped plate 86, and the bottom surfaces of both ends of the U-shaped plate 86 are fixed with a lifting rack rod 87. The interior of the lifting rack rod 87 is provided with an incomplete gear 88 that is rotatably connected to the outer surface of the frame 1. The incomplete gear 88 is meshed with the lifting rack rod 87. A rotating sleeve 89 coaxially fixed with the incomplete gear 88 is provided between the frame 1 and the incomplete gear 88. The end of the rotating sleeve 89 away from the incomplete gear 88 is coaxially fixed with the end of the adjusting roller 83. The hydraulic cylinder 85 drives the U-shaped plate 86 to rotate. When the plate 86 moves upward, it drives the lifting rack rod 87 to move upward synchronously, so that the lifting rack rod 87 and the incomplete gear 88 are meshed and transmitted, so that the incomplete gear 88 drives the rotating sleeve 89 to rotate synchronously with the incomplete gear 88, so that the adjusting roller 83 rotates along the axis of the incomplete gear 88 in the arc groove 82, so as to adjust the height difference between the adjusting roller 83 and the guide roller 81 on the frame 1, so that the metal wire is in a tight state when passing through the surfaces of the guide roller 81 and the adjusting roller 83, and the tension of the metal wire when it is wound and transported through the bottom surface of the guide roller 81 and the top surface of the adjusting roller 83 is adjusted, so as to further provide the tension of the metal wire during fine drawing, effectively avoid the situation of insufficient tension of the metal wire during fine drawing, make the metal wire evenly stressed during fine drawing, ensure the fine drawing reduction rate of the metal wire during fine drawing, and greatly improve its processing efficiency.

[0045] It is worth noting that when the hydraulic cylinder 85 drives the U-shaped plate 86 to move to the highest position, the adjusting roller 83 rotates to the lowest end of the arc groove 82. At this time, when the metal wire is conveyed on the bottom surface of the guide roller 81 and the top surface of the adjusting roller 83, the metal wire will be in a pressed state on the surface of the guide roller 81, which can be used to press the end of the metal wire when the winding drum 72 stops winding, thereby preventing the metal wire from loosening and causing the winding drum 72 to become loose.

[0046] Further as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it is worth explaining in detail that a coating mechanism 9 is arranged between the oil filling box 2 and the pulling roller 63, and the coating mechanism 9 includes an adsorption roller 91 rotatably connected to the opposite surfaces of the two frames 1, wherein the outer surface of the adsorption roller 91 is provided with adsorption cotton that fits the bottom surface of the metal wire, and the lubricating oil on the bottom surface of the metal wire is adsorbed and removed by the adsorption cotton, and a small amount of lubricating oil is preliminarily coated. Turntables 92 are coaxially fixed at both ends of the pulling roller 63 located below, and a rotating column 93 is fixed on the outer surface of the turntable 92. A limiting sleeve 94 fixed to the outer surface of the frame 1 is arranged on the outer side of the turntable 92, and the limiting sleeve 94 is The inner wall slides through the limit rod 95, and the outer surface of the rotating column 93 is provided with a limit ring 96 fixed to the end of the limit rod 95. A sliding rack 97 is fixed to the side of the limit ring 96 away from the limit rod 95. A connecting rod 98 is fixed to the opposite surfaces of the two sliding racks 97. The top surface of the connecting rod 98 is detachably connected to a coating sleeve 99. A rotating gear 910 rotatably connected to the outer surface of the frame 1 is provided above the sliding rack 97. A coating rod 911 slides through the inner walls of the two frames 1. Both ends of the coating rod 911 are fixed with a pushing rack 912. The bottom and top of the rotating gear 910 are respectively connected to the adjacent The sliding rack 97 and the pushing rack 912 are meshed and connected, wherein the turntable 92 and the rotating column 93 rotate synchronously with the rotation of the pulling roller 63. Due to the limiting effect of the limiting rod 95 on the limiting sleeve 94, and the rotating column 93 is always located inside the limiting ring 96, the reciprocating rotation of the turntable 92 can make the limiting rod 95 drive the limiting ring 96 to move back and forth in the limiting sleeve 94, and then drive the sliding rack 97 to move back and forth synchronously. Through the meshing reversing effect of the sliding rack 97, the rotating gear 910 and the pushing rack 912, the connecting rod 98 and the coating rod 911 are moved along the same direction. The coating rod 911 and the coating sleeve 99 perform synchronous reverse linear reciprocating motion on the surface of the metal wire, and the coating rod 911 coats the top surface of the metal wire, and the adsorption roller 91 coats the bottom surface of the metal wire in a small amount, thereby further improving the coating effect of the metal wire. Finally, the coating sleeve 99 coats the metal wire evenly again, so that there is a small amount of uniform lubricating oil film on the surface of the metal wire, thereby greatly improving the convenience of the winding mechanism 7 to wind up the finely drawn metal wire, and greatly improving its processing efficiency.

[0047] It is worth noting that during the process of fine drawing and surface reduction of the fine drawing model block 4, the adsorption roller 91 can guide the metal wire to a certain extent, and during the process of synchronous linear reverse reciprocating motion of the coating rod 911 and the coating sleeve 99 with trace lubricating oil on the surface of the metal wire, the distance between the coating rod 911 and the coating sleeve 99 reciprocates from near to far, further improving the guiding function of the surface of the metal wire, and forming a certain pulling treatment on the metal wire, effectively avoiding the loosening and deviation of the metal wire during the process of fine drawing and surface reduction, thereby improving the accuracy of the metal wire after transportation, pulling and winding.

[0048] Further as Figure 5 and Figure 7 As shown, it is worth explaining in detail that a fixed rod 10 fixed to the opposite surface of the two frames 1 is arranged above the adsorption roller 91, and a push ring 11 slidably sleeved on the outer surface of the adsorption roller 91 is arranged at both outer ends of the fine drawing model block 4, and the top of the push ring 11 is slidably sleeved on the outer surface of the fixed rod 10, and a push rod 12 is hinged between the push ring 11 and the coating rod 911, wherein the fixed rod 10 and the adsorption roller 91 perform movement and limit processing on the push ring 11, and in the process of the coating rod 911 reciprocating toward the fine drawing model block 4 Through the transmission action of the push rod 12, the push ring 11 moves synchronously toward the center of the metal wire under the limiting action of the fixed rod 10 and the adsorption roller 91, so that the adsorption cotton on the surface of the adsorption roller 91 can be squeezed, so that the lubricating oil adsorbed by the adsorption cotton can be squeezed and discharged, further ensuring the continuous adsorption effect of the adsorption cotton, thereby removing a large amount of lubricating oil on the bottom surface of the metal wire, so as to facilitate the subsequent re-lubricating oil film through the coating rod 911 and the coating sleeve 99 for uniform coating.

[0049] This scheme has the following working process: before the metal wire that has been treated with rough drawing and surface reduction is subjected to fine drawing, the front end of the metal wire is first pre-treated to the wire diameter required for fine drawing and surface reduction, and it passes through the conveying roller 61, the fine drawing model block 4, the adsorption roller 91, the coating rod 911, the coating sleeve 99, the pulling roller 63, the guide roller 81, and the adjusting roller 83 in sequence until it is installed with the winding drum 72 in a limited position. At this time, the variable frequency winding motor 73 and the traction motor 67 are driven synchronously, and the traction motor 67 drives the metal wire to pass the preliminary conveying of the conveying roller 61, and the fine drawing and surface reduction are carried out from the fine drawing model block 4 under the oil filling tank 2. The surface of the metal wire is lubricated by the lubricating oil in the oil filling tank 2, and then the metal wire is pulled by the pulling roller 63, so that The metal wire is guided and conveyed through the adsorption roller 91, the coating rod 911 and the coating sleeve 99, thereby improving the pulling effect of the pulling roller 63 on the metal wire. At the same time, the metal wire is adsorbed and removed from the bottom of the lubricating oil by the adsorption roller 91, and the coating rod 911 and the coating sleeve 99 perform synchronous linear reverse reciprocating motion, thereby uniformly coating the surface of the metal wire with a lubricating oil film. When the variable frequency winding motor 73 is winding, the hydraulic cylinder 85 is driven accordingly, thereby rotating and adjusting the height of the adjusting roller 83 at the arc groove 82, thereby ensuring that the metal wire maintains sufficient tension when the variable frequency winding motor 73 is winding the metal wire, thereby improving the winding and winding effect of the metal wire during fine drawing and surface reduction.

[0050] According to the above working process, it can be known that: through the function of the pulling and conveying mechanism 6 arranged before and after the fine drawing model block 4, the metal wire material to be unwound and the metal wire material after fine drawing are double pulled and conveyed, so as to effectively ensure the tension of the metal wire material before fine drawing, and by arranging the tension adjusting mechanism 8 at the front end of the winding mechanism 7, the tension of the metal wire material during fine drawing is further provided, so as to effectively avoid the situation that the tension of the metal wire material is insufficient during fine drawing, so that the metal wire material is evenly stressed during fine drawing, and the fine drawing reduction rate of the metal wire material during fine drawing is ensured, thereby greatly improving its processing efficiency;

[0051] The coating mechanism 9 operates synchronously with the pulling and conveying mechanism 6, which can not only effectively remove the lubricating oil on the surface of the metal wire and make a trace amount of lubricating oil evenly coated with the lubricating oil film, but also improve the guiding effect of the metal wire during pulling and conveying, and effectively prevent the metal wire from deflecting due to insufficient tension.
