Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper rod production, and particularly relates to a copper rod winding and pre-bending device. BACKGROUND

[0002] Copper rod is a necessary blank for producing copper wire rod for wire and cable, enameled wire, electronic wire, etc., and the copper wire rod is one of important basic materials for electronic, electrical and communication industries. With the development of world electronic telecommunication, the demand for copper wire rod in the wire and cable, enameled wire and electronic wire industries is also growing rapidly, thus driving the demand for copper rod to be increasingly large. At present, in the production and processing process of copper rod and the like, the copper rod is often packaged in a coiled state, and the copper rod needs to be pre-bent before winding to avoid loose winding of the copper rod.

[0003] In the prior art, as the copper rod is wound into a disc, the outer diameter of the copper rod disc gradually increases, and the bending radius of the copper rod also gradually increases. However, the curvature of the existing pre-bending mechanism for bending the copper rod is fixed. In the initial stage of winding the copper rod, the bending radius of the copper rod is small, and the curvature radius of the pre-bending of the copper rod is large, which leads to loose winding of the copper rod in the initial stage. As the winding of the copper rod proceeds, the bending radius of the copper rod gradually increases, and after a short time of adapting to the curvature radius of the pre-bending, the curvature radius of the pre-bending gradually becomes smaller than the bending radius of the copper rod, which leads to the copper rod in the later stage of winding to generate pressure on the inner copper rod, easily causing deformation of the copper rod, and the outer copper rod also extrudes the loose copper rod on the inner side, which also leads to loose winding, which needs to be solved urgently.

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the present invention discloses a copper rod winding pre-bending device, including a base 1, on which a plurality of slide blocks 8 are provided. The slide blocks 8 are slidably connected to the base 1. The plurality of slide blocks 8 are arranged on the base 1 in an arc-shaped trajectory with a central angle of 90 degrees. The plurality of slide blocks 8 are equally spaced on their arrangement trajectory, and the plurality of slide blocks 8 slide along the radial direction of their arrangement trajectory. The base 1 is provided with a slide rail at a corresponding position that is slidably connected to the slide blocks 8 and guides the sliding of the slide blocks 8.

[0034] The two ends of the track of the slide block 8 are the inlet end 7 and the outlet end 6, respectively. The copper rod enters through the slide block 8 at the inlet end 7, and after passing through multiple slide blocks 8 in sequence, the copper rod completes the pre-bending. Finally, the copper rod slides out through the slide block 8 at the outlet end 6.

[0035] A pull rod 13 is provided on the outer wall of the slide block 8. The pull rod 13 is horizontally arranged along the sliding direction of the slide block 8 and is located on the inner arc side of the arrangement trajectory of the slide block 8. A slide rod 12 is provided at the free end of the pull rod 13 and is vertically arranged.

[0036] The inner arc side of the slide block 8 is provided with an arc-shaped drive plate 10. The drive plate 10 is rotatably mounted on the base 1. The rotation axis of the drive plate 10 is located at the center of the arc-shaped arrangement of the slide block 8. The base 1 is provided with a motor that drives the drive plate 10 to rotate.

[0037] The drive plate 10 has multiple sliding grooves 11 at corresponding positions, each engaging with a plurality of sliding rods 12. The sliding rods 12 are slidably disposed within the sliding grooves 11. The sliding grooves 11 are arc-shaped, with their two ends located near the edge of the drive plate 10 and near the center of the drive plate 10, respectively, in the radial direction of the drive plate 10. The sliding grooves 11 can also be arc-shaped or straight, as long as there is a certain distance between the two ends of the sliding grooves 11 in the radial direction of the drive plate 10. When the drive plate 10 rotates, the sliding grooves 11 rotate accordingly. With the cooperation of the sliding rods 11, the sliding rods 12 slide along the sliding grooves 11, causing the sliding rods 12 to move closer to or away from the center of the drive plate 10. The sliding rods 12 drive the sliding blocks 8 to slide along the slide rail via the pull rod 13, thereby increasing or decreasing the diameter of the arrangement trajectory of the plurality of sliding blocks 8.

[0038] In addition to the drive board 10 and the motor, a cylinder can also be used as the driving source for the slide block 8. The cylinder is set on the base 1, and the piston rods of multiple cylinders are connected to multiple slide rods 12 respectively. The sliding direction of the cylinder piston rods corresponds to the sliding direction of the slide block 8. Multiple cylinders operate synchronously and drive multiple slide blocks 8 to slide synchronously, thereby achieving the purpose of changing the diameter of the arrangement trajectory of multiple slide blocks 8.

[0039] The clamping groove 14 in the slide 8 is horizontally through, and two curvature adjustment wheel sets 5 are arranged in the clamping grooves 14 of the plurality of slides 8 and slide between the clamping grooves 14 of the plurality of slides 8. The curvature adjustment wheel set 5 comprises a plurality of equally spaced roller wheels 51, and the wheel surface of the roller wheel 51 is concave and arc-shaped, so as to increase the contact area between the roller wheel 51 and the copper rod. The curvature adjustment wheel set 5 further comprises two chains 52, and the two chains 52 are respectively arranged at the two ends of the roller wheel 51 and are rotationally connected to the roller wheel 51 at the two ends.

[0040] The top and bottom of the clamping groove 14 are respectively slidably provided with two adjusting sliding blocks 16, and the sliding directions of the two adjusting sliding blocks 16 are in the same radial direction of the arrangement track of the slide 8. The upper part and the lower part of the clamping groove 14 are respectively rotationally provided with adjusting screws 19, the adjusting screws 19 are arranged along the sliding direction of the adjusting sliding block 16, one end of the adjusting screw 19 is rotationally connected to the side wall of the clamping groove 14, and the other end of the adjusting screw 19 is provided with a first bevel gear 18 coaxial with the adjusting screw 19. The adjusting screws 19 of the upper part and the lower part of the clamping groove 14 are respectively threadedly connected to the two adjusting sliding blocks 16 clamping the upper part and the lower part, and the middle of the two adjusting sliding blocks 16 is taken as a separation point, the screw thread directions of the adjusting screws 19 on the two sides of the separation point are opposite, so that when the adjusting screws 19 are rotationally threadedly connected to the two adjusting sliding blocks 16, the two adjusting sliding blocks 16 are synchronously and oppositely slid to approach or move away from each other.

[0041] The clamping groove 14 on the side of the first bevel gear 18 is rotationally provided with a vertically arranged transmission rod 15, the bottom end of the transmission rod 15 is rotationally connected to the bottom of the clamping groove 14, the top end of the transmission rod 15 penetrates through the top of the slide 8 and is rotationally connected to the top of the slide 8, and the top end of the transmission rod 15 is provided with a hand wheel 9 coaxial with the transmission rod 15. The transmission rod 15 is provided with a second bevel gear 17 engaged with the transmission rod 15 on the side of the transmission rod 15, and the second bevel gear 17 is coaxially connected to the transmission rod 15. Rotating the hand wheel 9, the transmission rod 15 is rotated, the two second bevel gears 17 are synchronously rotated to drive the two first bevel gears 18 to be synchronously rotated, and the two adjusting screws 19 are synchronously rotated to drive the two adjusting sliding blocks 16 at the top and the bottom of the clamping groove 14 to be synchronously approached or moved away from each other.

[0042] Except for the slide 8 at the entering end 7, the side walls of the adjusting sliding blocks 16 at the top and the bottom of the clamping groove 14 of the rest of the slides 8 are respectively provided with guide rails 20, the guide rails 20 are chain guide rails, and the guide rails 20 are slidably connected to the chains 52 of the curvature adjustment wheel set 5. Through the sliding connection with the guide rails 20, the sliding tracks of the two curvature adjustment wheel sets 5 between the plurality of slides 8 are in the shape of a circular arc parallel to the arrangement track of the slide 8. By adjusting the distance between the two adjusting sliding blocks 16, the distance between the two curvature adjustment wheel sets 5 is adjusted, so that the distance between the roller wheels 51 of the two curvature adjustment wheel sets 5 is adapted to the outer diameter of the copper rod, the copper rod is conveyed between the roller wheels 51, and the pre-bending of the copper rod is completed.

[0043] The side of the slide 8 at the output end 6 is provided with two tensioning mechanisms, both of which are arranged on the base 1 and are located on both sides of the output direction of the copper rod, and both of which are used to tension the two curvature adjustment wheel sets 5 respectively.

[0044] The tensioning mechanism comprises a tensioning roller 2 arranged rotatably on the base 1, which is arranged vertically, and a tensioning rope 3 wound on the tensioning roller 2, which can be a steel wire rope. A torsional spring is arranged between the tensioning roller 2 and the base 1, and the force points at both ends of the torsional spring are connected with the base 1 and the tensioning roller 2 respectively. One end of the tensioning rope 3 is fixedly connected with the tensioning roller 2, and the other end of the tensioning rope 3 is provided with a pulling block 4.

[0045] The guide rail 20 is not arranged in the clamping groove 14 of the slide 8 at the entering end 7, and one end of the two curvature adjustment wheel sets 5 is located in the clamping groove 14 of the slide 8, and the two chain ends 52 of the two curvature adjustment wheel sets 5 are rotatably connected with the adjusting slide 16 in the clamping groove 14 of the slide 8. The two curvature adjustment wheel sets 5 pass through the clamping grooves 14 of multiple slides 8 in sequence, the chain 52 is slidably connected with the guide rail 20 in the clamping groove 14 of the slide 8, and the two curvature adjustment wheel sets 5 are output by the slide 8 at the output end 6, and the chain 52 at the end of the curvature adjustment wheel set 5 is rotatably connected with the pulling block 4 of the two tensioning mechanisms. Under the elastic force of the torsional spring, the tensioning roller 2 rotates unidirectionally to wind the tensioning rope 3, the tensioning rope 3 is pulled to wind the curvature adjustment wheel set 5, so that the curvature adjustment wheel set 5 is tightened between multiple slides 8, and the two curvature adjustment wheel sets 5 are in the shape of circular arcs with the same center, and the copper rod passes between the two curvature adjustment wheel sets 5.

[0046] The copper rod enters the clamping groove 14 of the slide 8 at the entering end 7 and is located between the two curvature adjustment wheel sets 5, the rollers 51 of the two curvature adjustment wheel sets 5 clamp and guide the copper rod on both sides of the copper rod, the copper rod is conveyed along the track of the two curvature adjustment wheel sets 5, and the copper rod is conveyed into the clamping groove 14 of the slide 8 at the output end 6 and is output therefrom, thereby completing the pre-bending. Since the two tensioning mechanisms are located on both sides of the output direction of the copper rod, and the two curvature adjustment wheel sets 5 are connected with the two tensioning mechanisms respectively, the curvature adjustment wheel set 5 and the tensioning mechanism will not interfere with the output of the copper rod. As the copper rod is wound, the bending radius of the copper rod changes gradually, the motor drives the driving plate 10 to rotate, so that multiple slides 8 slide synchronously, and the curvatures of the two curvature adjustment wheel sets 5 change to adapt to the current bending radius of the copper rod. According to the outer diameter of the copper rod, the hand wheel 9 on the slide 8 is rotated, the transmission rod 15 is rotated to drive the adjusting screw 19 to rotate, the distance between the two adjusting slides 16 is adjusted, so that the distance between the two curvature adjustment wheel sets 5 is adjusted to adapt to the outer diameter of the copper rod.

[0047] The present application pre-bends the copper rod through two curvature adjustment wheel sets 5, which can adjust the curvature according to the bending radius of the copper rod, so that it is matched with the bending radius of the copper rod, avoiding the mismatch between the curvature of the copper rod pre-bending and the current bending radius of the copper rod. While changing the curvature, the plurality of rollers 51 keeps equal interval, so that the copper rod is always uniformly stressed. The interval of the two adjusting sliders 16 can be adjusted, so that the interval of the two curvature adjustment wheel sets 5 is matched with the outer diameter of the copper rod, so as to be suitable for copper rods of different sizes.

[0048] The above embodiments are only the preferred embodiments of the present application, and are not a limitation on the technical solutions of the present application.
