Description

Technical Field

[0001] This utility model belongs to the field of metal wire drawing technology, and more specifically, relates to a wire drawing device for copper conductor production. Background Technology

[0002] The cable processing technology mainly includes three processes: drawing, stranding and sheathing. Among them, the drawing process mainly uses external force to force the thick copper wire through the drawing die, so that the cross-sectional area of ​​the thick copper wire is compressed, thereby obtaining the required cross-sectional shape and size. The copper wire drawing process mainly includes four steps: unwinding, drawing, annealing and winding. The utility model application CN202121582237.7 (announcement number CN215614122U) discloses a mobile tower wheel type copper wire multi-die drawing machine, including a take-up reel, a snap fastener assembly, a fixing plate, a heating assembly, copper wire, a worktable, and a lubrication assembly. A control box is fixedly connected to the side wall of the worktable, and a fixing plate is fixedly fixed to the upper end of the control box on the upper surface of the worktable. A take-up reel is rotatably connected to the side wall of the fixing plate, and a snap fastener assembly for limiting the copper wire is fixedly connected to the side wall of the take-up reel. A tower wheel is provided on one side of the take-up reel, and a heating assembly for heating and drawing the wire is provided on one side of the tower wheel. The heating assembly is fixedly connected to the upper surface of the worktable. A limiting seat is provided, and a rotating seat is rotatably connected in the limiting seat. A reciprocating rod is fixed to the upper side of the rotating seat. The reciprocating rod drives a piston at one end to reciprocate in the oil chamber, thereby pushing the lubricant into the lubrication groove to lubricate the copper wire. The aforementioned patent uses a piston to squeeze the copper wire in an oil chamber, thereby providing lubricant in the connection hole of the lubrication groove. The lubricant lubricates the copper wire. However, since the piston's stroke is consistent each time, the amount of lubricant squeezed out each time is not adjustable and cannot be adjusted according to the copper wire diameter or drawing speed. Utility Model Content

[0003] In view of this, the present invention provides a wire drawing device for copper conductor production, which solves the technical problem that the amount of lubricant used in extrusion is not adjustable and cannot be adjusted according to the diameter of the copper wire and the drawing speed.

[0004] This utility model is implemented as follows: This utility model provides a wire drawing device for copper conductor production, which has a workbench, a vertical plate fixedly installed on the workbench, an oil cylinder provided on the vertical plate, a lubrication block fixedly connected to the lower end of the oil cylinder, a plurality of lubrication grooves fixedly connected on the lubrication block, the lubrication grooves being semi-arc-shaped, and connection holes provided in the lubrication grooves; The cylinder is slidably connected to a piston, and the left side of the vertical plate is provided with an oil injection assembly that drives the piston to reciprocate.

[0005] Based on the above technical solution, the wire drawing device for copper conductor production of this utility model can be further improved as follows: Furthermore, one end of a piston rod is fixedly mounted on the piston, and the other end of a connecting rod is hinged to the other end of the piston rod, with the other end of the connecting rod located on the turntable.

[0006] Furthermore, the fuel injection assembly includes a turntable that rotates in place on one side of the oil cylinder, a screw that is rotatably connected to the turntable, and a screw block that is cylindrical is fitted onto the screw.

[0007] Furthermore, the outer circumferential surface of the screw block is provided with a plurality of protrusions A at equal intervals, and a retaining plate is provided on one side of the screw block. The inner wall of the retaining plate is provided with a plurality of protrusions B at equal intervals, and one of the protrusions B is located between two adjacent protrusions A.

[0008] Furthermore, an adjusting block is rotatably connected to the outside of the screw block, and one end of the connecting rod located on the turntable is hinged to the front wall of the adjusting block.

[0009] Furthermore, a through groove is provided on the transverse side wall of the adjusting block, and the locking plate is slidably connected in the through groove on one side of the screw block.

[0010] Furthermore, a fixing plate is fixedly installed on the outer wall of the adjusting block. The fixing plate has a threaded hole, and a bolt is threaded into the threaded hole. The inner end of the bolt abuts against the outer wall of the clamping plate.

[0011] Compared with the prior art, the beneficial effects of the wire drawing device for copper conductor production provided by this utility model are: By adjusting the position of the adjusting screw block, one end of the connecting rod on the turntable can be moved, thus changing the stroke of the piston rod and adjusting the oil output to adapt to different specifications of copper wire drawing. By setting protrusions A and B, the rotation of the screw block can be restricted, preventing the screw block from moving during the rotation of the turntable. The stroke of the piston can be adjusted to prevent excessive lubricant from adhering when the copper wire diameter is small, which would cause the copper wire to stick during subsequent winding. It can also prevent insufficient lubrication when the copper wire diameter is large, which would cause increased friction between the copper wire and the drawing die, resulting in scratches or breakage on the copper wire surface.

The lubricating grooves 21 are semi-arc-shaped and have connecting holes. The cylinder 31 is slidably connected to a piston 32, and the left side of the vertical plate 11 is provided with an oil injection assembly that drives the piston 32 to move back and forth.

[0020] Optionally, in the above technical solution, one end of the piston rod 33 is fixedly mounted on the piston 32, and one end of the connecting rod 34 is hinged to the other end of the piston rod 33. The other end of the connecting rod 34 is located on the turntable 41.

[0021] Optionally, in the above technical solution, the fuel injection assembly includes a turntable 41 that rotates in place on one side of the oil cylinder 31, a screw 42 that is rotatably connected to the turntable 41, and a screw block 43 that is sleeved on the screw 42.

[0022] Furthermore, a support base 12 is fixedly installed on the left side of the upright plate 11. The support base 12 is rotatably connected to a rotating shaft 13. The front end of the rotating shaft 13 is fixedly connected to the turntable 41, and the two are concentrically arranged. A motor base is fixedly installed on the rear wall of the support base 12. A drive motor is fixedly installed on the motor base. The output shaft of the drive motor extends forward and its end is connected to the rotating shaft 13.

[0023] Furthermore, two bearing seats 4 are installed on the turntable 41 (one end of the bearing seat 4 is located at the center of the turntable 41 and the other end is located at the outer edge of the turntable 41). A screw 42 is rotatably connected inside the bearing seat 4 via a bearing, and a rotating handle is installed at the top of the screw 42.

[0024] Optionally, in the above technical solution, the outer peripheral surface of the screw block 43 is provided with a plurality of protrusions A44 at equal intervals, and a retaining plate 45 is provided on one side of the screw block 43. The inner wall of the retaining plate 45 is provided with a plurality of protrusions B46 at equal intervals, and a protrusion B46 is located between two adjacent protrusions A44.

[0025] Preferably, the bump B46 has a triangular structure, and the surface where the bump A44 and the bump B46 mate is an inclined surface, which facilitates the insertion of the bump B46 between the two bumps A44; preferably, the number of bumps B46 is greater than one.

[0026] Optionally, in the above technical solution, the screw block 43 is externally rotatably connected to an adjusting block 47, and one end of the connecting rod 34 located on the turntable 41 is hinged to the front wall of the adjusting block 47.

[0027] Optionally, in the above technical solution, a through groove is provided on the transverse side wall of the adjusting block 47, and a retaining plate 45 is slidably connected in the through groove on one side of the screw block 43.

[0028] Optionally, in the above technical solution, a fixing plate 48 is fixedly installed on the outer wall of the adjusting block 47. The fixing plate 48 has a threaded hole, and a bolt 49 is threaded into the threaded hole. The inner end of the bolt 49 abuts against the outer wall of the clamping plate 45.

[0029] Furthermore, one end of a spring 51 is fixedly installed on the outer wall of the card plate 45, and the other end of the spring 51 is fixedly installed on the fixed plate 48.

[0030] It also includes an oil tank, and the oil tank and oil cylinder 31 are connected by a pipeline, with a one-way valve installed on the connecting pipeline.

[0031] A handle 40 is fixedly installed on the end face near the outer edge of the turntable 41.

[0032] Working principle: When in use, start the drive motor to make it rotate the turntable 41 in place through the rotating shaft 13. One end of the connecting rod 34 follows and rotates in a circle. The other end pushes the piston rod 33 to drive the piston 32 to move in a straight line. The piston 32 is squeezed in the oil cylinder 31, so that there is lubricant in the connection hole of the lubrication groove 21, and the lubricant lubricates the copper wire. Turning the handle 40 causes the screw 42 to rotate in place and drives the screw block 43, which is threaded to it, to move circumferentially along the central axis of the screw 42, thereby changing the eccentric position of the connecting rod 34 on the oil cylinder 31 (i.e., the distance between the screw block 43 and the rotation center of the turntable 41). Specifically, when the screw block 43 is closer to the center of the turntable 41, the transmission radius decreases, the piston 32 has a shorter single stroke, and the oil cylinder 31 outputs less oil per stroke; when the screw block 43 is farther away from the center of the turntable 41, the transmission radius increases, the piston 32 has a longer single stroke, and the oil cylinder 31 outputs more oil per stroke. Once adjusted to the appropriate position, to prevent the screw block 43 from moving due to equipment vibration and other factors, which could lead to errors in the oil injection volume, the position of the screw block 43 can be limited. Specifically, the bolt 49 is rotated and moved towards the clamping plate 45 until it abuts against the outer wall of the clamping plate 45. During the movement, the push plate 45 is displaced against the elastic force of the spring 51 until the plate 45 is attached to the outer wall of the screw block 43 (the protrusions A44 and B46 are engaged, and the protrusion B46 is inserted between the two protrusions A44), which can restrict the circumferential rotation between the screw block 43 and the screw rod 42, thereby preventing the screw block 43 from generating axial displacement on the screw rod 42; Since the screw block 43 may not always maintain precise alignment after the screw block 43 moves, a certain space is reserved between the outer wall of the clamping plate 45 and the inner wall of the fixing plate 48. When the bolt 49 abuts against the outer wall of the clamping plate 45, the clamping plate 45 can tilt slightly. Through the adaptive adjustment of the inclined surface, the protrusion B46 can better fit against the protrusion A44 to ensure the clamping effect. When the restriction is released, the bolt 49 does not abut against the spring 51, and the spring 51 returns the plate 45 to its original position. The rear protrusion B46 of the plate 45 moves away from the protrusion A44 (wherein, the bottom wall of the plate 45 is slidably connected to the fixed plate 48).

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
