Description

Technical Field

[0001] The present invention relates to the technical field of metal wire drawing equipment, and particularly relates to a device for copper rod processing. Background Art

[0002] In the production process of copper wires used in wire and cable, they are mostly made into fine wires of different specifications through wire drawing devices to meet the requirements of various voltage levels and application scenarios. When using a wire drawing device to draw a copper rod, the processed copper rod needs to pass through dies with different apertures. When the copper rod passes through dies with different diameters, its diameter is continuously reduced until it is drawn into a copper wire that meets the diameter requirements. During the process of drawing the copper rod, when a bent or non-straight copper rod enters the die, it will be subjected to additional stress concentration points. The copper rod is more likely to break at these stress points during the drawing process, resulting in production interruption, increasing waste products, and reducing production efficiency due to frequent shutdowns. In addition, when the copper rod enters the die in a non-linear state, the contact between the copper rod and the die is uneven, which may also cause local excessive friction of the copper rod, resulting in scratches, pits or other defects on the surface of the finished copper wire, affecting the appearance quality and service performance of the finished product.

[0003] The patent document with the authorization announcement number CN221209410U discloses a copper rod wire drawing device, including an oil box. A first notch is opened on one side of the oil box, and a second notch is opened on the other side of the oil box. A fixed die box is fixedly connected inside the second notch, and a wire drawing die is installed inside the fixed die box. A steering pulley is movably sleeved inside the oil box, lubricating oil is stored inside the oil box, and the liquid level of the lubricating oil is at the middle position of the steering pulley. A fixed frame assembly is provided inside the oil box, and a longitudinal positioning wheel is movably sleeved inside the fixed frame assembly.

[0004] The above patent document positions the copper rod processing workpiece vertically and longitudinally through the longitudinal positioning wheel and the longitudinal positioning mechanism, so that the copper rod processing piece is horizontally aligned with the inner cavity of the wire drawing die, avoiding the generation of a fold angle between the copper wire processing piece and the wire drawing die. In the actual production process, affected by the storage state and transportation of the copper rod, some positions of the copper rod are bent before entering the die. The above patent document can position the copper rod when it enters the wire drawing die, but it cannot straighten and correct the bent part of the copper rod when the copper rod is bent, resulting in an unsatisfactory wire drawing effect of the copper rod. Summary of the Invention

[0005] The present invention provides a device for copper rod processing, aiming to solve the problem in the related technology that the equipment for wire drawing processing of copper rods is inconvenient to straighten and correct the bent part of the copper rod in time when the copper rod is bent, resulting in an unsatisfactory wire drawing effect of the copper rod.

[0006] A device for processing copper rods according to the present invention includes a machine body and a mounting seat provided on the machine body. A conveying mechanism and a calibration mechanism are provided on the mounting seat. The conveying mechanism includes a first guiding assembly, a second guiding assembly, an adjusting assembly, and a driving assembly. Taking the side facing the movement of the copper rod as the front side, the second guiding assembly is located in front of the first guiding assembly. The first guiding assembly includes two first guiding wheels, and the second guiding assembly includes two second guiding wheels. The copper rod passes through between the two first guiding wheels and the two second guiding wheels. The driving assembly drives the two first guiding wheels to rotate relatively, and the adjusting assembly is used to synchronously adjust the spacing between the two first guiding wheels and the two second guiding wheels. The calibration mechanism is located between the first guiding assembly and the second guiding assembly. The calibration mechanism includes a calibration cylinder, a transmission assembly, and a limiting assembly. The calibration cylinder is connected to the limiting assembly through the transmission assembly. The copper rod passes through the calibration cylinder, and when the copper rod axially deviates, the limiting assembly is triggered by the transmission assembly to lock the two first guiding wheels.

[0007] The beneficial effects are as follows: It is convenient to automatically straighten the bent part of the copper rod during the drawing process of the copper rod. The adjusting assembly adjusts the spacing between the two first guiding wheels and the two second guiding wheels according to the diameter of the copper rod. The driving assembly drives the two second guiding wheels to rotate relatively. When the second guiding wheels rotate, the copper rod is conveyed. The calibration mechanism is between the first guiding assembly and the second guiding assembly. The copper rod passes through the calibration cylinder. The calibration cylinder is connected to the limiting assembly through the transmission assembly. When the copper rod is bent, the bent part of the copper rod passes through the calibration cylinder and drives the calibration cylinder to move. The calibration cylinder further activates the limiting assembly through the transmission assembly. The limiting assembly locks the two first guiding wheels. The two first guiding wheels clamp the rear side of the bent section of the copper rod, and the second guiding wheels continuously convey the copper rod forward, so that the copper rod is straightened during the action of being clamped at one end and continuously conveyed forward at the other end, realizing automatic calibration and correction during the drawing and feeding process of the copper rod, and ensuring the drawing quality of the copper rod.

[0008] Preferably, the transmission assembly includes a connecting rod, a turntable, and an adjusting rod. The turntable is rotatably connected to the mounting seat through a torsion spring. A chute parallel to the radius of the turntable is provided on the turntable. One end of the connecting rod is fixed to the calibration cylinder, and the other end of the connecting rod is slidably matched with the chute.

The adjusting rod is slidably matched with the mounting seat along its axis. One end of the adjusting rod is connected to the limiting assembly.

[0009] The beneficial effects are as follows: The flexibility of straightening the copper rod is improved. The calibration cylinder is fixed to the connecting rod, and the connecting rod can slide relative to the mounting base along its axial direction and vertical direction. That is, when the copper rod passing through the calibration cylinder is bent in different directions, the calibration cylinder can drive the connecting rod to slide relative to the mounting base. When the connecting rod slides relative to the mounting base, it further drives the turntable to rotate through the sliding groove. When the turntable rotates, the adjusting rod slides along its own axis through the sliding fit between the spiral groove and the convex block. The adjusting rod is connected to the limiting component, and the movement of the calibration cylinder is smoothly transmitted to the limiting component.

[0010] Preferably, the limiting component includes a movable rod, a movable plate, a guide rod and a limiting insertion block. The middle part of the movable rod is rotatably connected to the mounting base. The lower end of the movable rod is rotatably assembled and slidably connected to the adjusting rod. The movable rod is in contact with the movable plate. The movable plate is slidably connected to the mounting base. The guide rod is arranged parallel to the movable plate and elastically connected. A limiting slot is provided on the first guide wheel. One end of the limiting insertion block is slidably matched with the guide rod, and the other end of the limiting insertion block is movably inserted into the limiting slot. The limiting insertion block moves up and down synchronously with the first guide wheel.

[0011] Preferably, a guide groove is provided at the lower end of the movable rod. One end of the adjusting rod is slidably and rotatably connected to the guide groove.

[0012] Preferably, a connecting shaft extends from one end of the first guide wheel. The connecting shaft is rotatably matched with the mounting base. A connecting block is longitudinally slidably arranged on the mounting base. The connecting shaft is rotatably matched with the connecting block. A connecting groove is provided on the connecting block opposite to the limiting slot. The limiting insertion block is slidably matched with the connecting groove.

[0013] Preferably, a spring is sleeved between the guide rod and the connecting block of the limiting insertion block. When the limiting insertion block is inserted into the limiting slot, the spring is deformed and stores energy by extrusion.

[0014] The beneficial effects are as follows: It is convenient to quickly lock the two first guide wheels when the copper rod is bent. When the adjusting rod slides relative to the mounting base, it drives the movable plate to slide through the movable rod. The movable plate further drives the limiting insertion block to slide in the connecting groove through the guide rod. When the limiting insertion block is opposite to the limiting slot, the limiting insertion block is inserted into the limiting slot and blocks the rotation of the first guide wheel.

[0015] Preferably, two limiting plates are fixed on the mounting base. The two connecting blocks longitudinally slide between the two limiting plates in contact with the limiting plates. A vertical groove is provided on the limiting plate adjacent to the guide rod. The limiting insertion block passes through the groove and is slidably matched with the limiting plate.

[0016] Preferably, the adjusting assembly includes a first adjusting seat, a second adjusting seat, a first rack, a second rack and a gear. The first adjusting seat and the second adjusting seat are both in lifting cooperation with the mounting seat. The first adjusting seat is located above the second adjusting seat. The upper guide wheels 1 and 2 are rotatably connected to the first adjusting seat, and the lower guide wheels 1 and 2 are rotatably connected to the second adjusting seat. The first rack is fixed to the first adjusting seat, the second rack is fixed to the second adjusting seat, and the gear meshes with both the first rack and the second rack simultaneously.

[0017] The beneficial effects are as follows: to ensure the conveying accuracy of the copper rod. When the adjusting assembly adjusts the distance between the two guide wheels 1 and the two guide wheels 2, the first adjusting seat moves up and down relative to the mounting seat, and the first rack moves up and down synchronously with the first adjusting seat. Under the driving action of the gear, the second rack moves in the opposite direction relative to the first rack, and the second rack drives the second adjusting seat to move in the opposite direction relative to the first adjusting seat, so that the distance between the two guide wheels 1 and the two guide wheels 2 adapts to the diameter of the copper rod to become larger or smaller. Moreover, when the adjusting assembly adjusts the distance between the two guide wheels 1 and the two guide wheels 2, the axis of the copper rod will not shift up and down, effectively ensuring the conveying accuracy of copper rods with different diameters.

[0018] Preferably, the driving assembly includes a driving source and a driving shaft. The ends of both of the two guide wheels 2 extend with rotating shafts, and end face gears are fixed to the ends of the two rotating shafts. The driving source is installed on the mounting seat, the driving source drives the driving shaft to rotate, and a tooth part that meshes with both of the two end face gears is provided on the driving shaft.

[0019] Preferably, the first adjusting seat is connected with an adjusting handle. The adjusting handle is in rotational cooperation with the mounting seat, and the first adjusting seat is threadedly connected to the adjusting handle.

[0020] The beneficial effects are as follows: to facilitate the quick adjustment of the distance between the two guide wheels 1 and the two guide wheels 2. The first adjusting seat is threadedly connected to the adjusting handle. Rotating the adjusting handle can make the first adjusting seat move up and down relative to the mounting seat, and the operation is convenient and fast.

[0021] The beneficial effects of the present invention are as follows: It is convenient to automatically straighten the bent part of the copper rod during the drawing process of the copper rod. The adjusting component adjusts the distance between the two first guide wheels and the two second guide wheels according to the diameter of the copper rod. The driving component drives the two second guide wheels to rotate relative to each other. When the second guide wheels rotate, the copper rod is conveyed. The calibration mechanism is between the first guiding component and the second guiding component. The copper rod passes through the calibration cylinder. The calibration cylinder is connected to the limiting component through the transmission component. When the copper rod is bent, the bent part of the copper rod passes through the calibration cylinder and drives the calibration cylinder to move. The calibration cylinder further activates the limiting component through the transmission component. The limiting component locks the two first guide wheels. The two first guide wheels clamp the rear side of the bent section of the copper rod. The second guide wheels continuously convey the copper rod forward, so that the copper rod is straightened during the action of being clamped at one end and continuously conveyed forward at the other end, realizing automatic calibration and correction during the drawing and feeding process of the copper rod, and ensuring the drawing quality of the copper rod.

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0031] As Figure 1 and Figure 2 shown, the device for processing copper rods of the present invention includes a body 1, a mounting base 2 provided on the body 1, and a conveying mechanism and a calibration mechanism provided on the mounting base 2. The conveying mechanism is used to convey the copper rods to be drawn. The conveying mechanism includes a first guiding component, a second guiding component, an adjusting component and a driving component. Taking the side facing the conveying direction of the copper rod as the front side, the second guiding component is located in front of the first guiding component. The first guiding component includes two first guide wheels 23, and the second guiding component includes two second guide wheels 24. The copper rod passes through between the two first guide wheels 23 and the two second guide wheels 24, and the copper rod is in contact with the first guide wheels 23 and the second guide wheels 24. The driving component drives the two second guide wheels 24 to rotate relatively. When the two second guide wheels 24 rotate relatively, the conveyed copper rod moves, and when the copper rod moves, it further drives the two first guide wheels 23 to rotate relatively. The adjusting component is used to adjust the distance between the two first guide wheels 23 and the two second guide wheels 24 according to the diameters of different copper rods, so that both the two first guide wheels 23 and the two second guide wheels 24 are kept in a state of being in contact with the copper rod. The calibration mechanism is located between the first guiding component and the second guiding component, and is used to straighten and calibrate the conveyed copper rod when it is detected that the copper rod is bent.

[0032] As Figure 2As shown in the figure, the adjusting assembly includes a first adjusting seat 21, a second adjusting seat 22, a first rack 211, a second rack 221, and a gear 212. Both the first adjusting seat 21 and the second adjusting seat 22 are in lifting cooperation with the mounting seat 2. The first adjusting seat 21 is located above the second adjusting seat 22. The first guide wheels 23 and the second guide wheels 24 located on the upper side are rotatably connected to the first adjusting seat 21, and the first guide wheels 23 and the second guide wheels 24 located on the lower side are rotatably connected to the second adjusting seat 22. The first rack 211 is fixed to the first adjusting seat 21, the second rack 221 is fixed to the second adjusting seat 22, and the gear 212 is rotatably mounted on the mounting seat 2. The gear 212 is simultaneously engaged with the first rack 211 and the second rack 221.

[0033] The first adjusting seat 21 is connected with an adjusting handle 25. The adjusting handle 25 is in rotational cooperation with the mounting seat 2, and the first adjusting seat 21 is in threaded connection with the adjusting handle 25. When adjusting the distance between the two first guide wheels 23 and the two second guide wheels 24 according to the diameter of the copper rod, rotate the adjusting handle 25. The first adjusting seat 21 moves up and down relative to the mounting seat 2, and the first rack 211 moves up and down synchronously with the first adjusting seat 21. Under the driving action of the gear 212, the second rack 221 moves in the opposite direction relative to the first rack 211. The second rack 221 drives the second adjusting seat 22 to move in the opposite direction relative to the first adjusting seat 21, so that the distance between the two first guide wheels 23 and the two second guide wheels 24 adapts to the diameter of the copper rod to become larger or smaller. And when the adjusting assembly adjusts the distance between the two first guide wheels 23 and the two second guide wheels 24, the axis of the copper rod will not shift up and down, effectively ensuring the conveying accuracy of copper rods with different diameters.

[0034] As Figure 2 , Figure 3 and Figure 5 shown in the figure, the driving assembly includes a driving source 245 and a driving shaft 243. The ends of both the second guide wheels 24 extend with rotating shafts 241, and end face gears 242 are fixed to the ends of the two rotating shafts 241. The driving source 245 can be a motor. The driving source 245 is installed on the mounting seat 2. The driving source 245 drives the driving shaft 243 to rotate. A tooth portion 244 that is simultaneously engaged with the two end face gears 242 is provided on the driving shaft 243. When the driving source 245 works, it drives the driving shaft 243 to rotate. The driving shaft 243 drives the two end face gears 242 to rotate synchronously in the opposite direction through the tooth portion 244, and further drives the two second guide wheels 24 to rotate synchronously in the opposite direction, realizing the continuous conveying of the copper rod.

[0035] Figures 2 to 7As shown, the calibration mechanism includes a calibration cylinder 3, a transmission component, and a limit component. Both the calibration cylinder 3 and the limit component are connected to the transmission component. The calibration cylinder 3 is adapted to the axis change of the copper rod and is movably engaged with the mounting seat 2. That is, when the copper rod passes through the calibration cylinder 3 in a straight state, the calibration cylinder 3 is coaxial with the copper rod and the position of the calibration cylinder 3 does not move relative to the mounting seat 2. If the copper rod passes through the calibration cylinder 3 in a bent state, the bent part of the copper rod pushes the calibration cylinder 3 to move relative to the mounting seat 2. The calibration cylinder 3 is connected to the limit component through the transmission component. When the copper rod is bent, the calibration cylinder 3 triggers the limit component through the transmission component, and the limit component locks the two first guide wheels 23 to restrict the rotation of the two first guide wheels 23. The two second guide wheels 24 rotate normally. When the first guide wheels 23 stop rotating, they clamp the copper rod, causing the copper rod to move out of sync when passing through the first guide component and the second guide component, thereby straightening the part of the copper rod between the first guide component and the second guide component. After the copper rod is straightened, the calibration cylinder 3 resets, and the transmission component and the limit component reset, releasing the lock on the first guide wheels 23, causing the first guide wheels 23 to rotate again and convey the copper rod normally.

[0036] As Figure 2 and Figure 4 shown, the transmission component includes a connecting rod 31, a turntable 33, and an adjusting rod 34. One end of the connecting rod 31 is fixed to the calibration cylinder 3, and the other end of the connecting rod 31 is slidably connected to the turntable 33. The connecting rod 31 is also slidably assembled with the mounting seat 2 in both its axial direction and the vertical direction, and a return spring is connected to the connecting rod 31 in its sliding direction. Specifically, a slider 32 is slidably sleeved on the middle of the connecting rod 31, and the connecting rod 31 is slidably engaged with the slider 32 along its own axis direction. The slider 32 is slidably connected to the mounting seat 2 in the vertical direction. The return spring can be a compression spring. Two compression springs are sleeved on the connecting rod 31, and the two compression springs are respectively located on both sides of the slider 32. The upper side and the lower side of the slider 32 are each connected to the mounting seat 2 through a compression spring. When the copper rod passes through the calibration cylinder 3 in a straight state, the copper rod does not exert extrusion on the calibration cylinder 3, and the two compression springs connecting the slider 32 and the two compression springs on the connecting rod 31 are in a balanced state.

[0037] The turntable 33 is provided with a chute 331, the length direction of the chute 331 is parallel to the radial direction of the turntable 33, the turntable 33 is rotationally connected to the mounting seat 2 through a torsion spring, the end of the connecting rod 31 extends into the chute 331 and is in sliding fit with the chute 331, a spiral groove 332 is provided on the outer peripheral side of the adjusting rod 34, the adjusting rod 34 is slidably connected to the mounting seat 2 along its own axis, and the adjusting rod 34 does not rotate around its own axis. A convex block is provided on the adjusting rod 34, the convex block extends into the spiral groove 332 and is in sliding fit with the spiral groove 332. When the part of the copper rod passing through the calibration cylinder 3 is bent, the copper rod presses the calibration cylinder 3 to move. When the connecting rod 31 moves with the calibration cylinder 3, it slides relative to the chute 331 on the turntable 33 and pushes the turntable 33 to rotate. When the turntable 33 rotates, it pushes the adjusting rod 34 to slide along its own axis through the convex block.

[0038] One end of the adjusting rod 34 is connected to the limiting component, as Figures 5 to 7 shown, the limiting component includes a movable rod 4, a movable plate 41, a guide rod 42 and a limiting insert block 43. A limiting shaft 401 is fixed on the mounting seat 2, the middle part of the movable rod 4 is rotationally connected to the limiting shaft 401, and the lower end of the movable rod 4 is rotationally assembled and slidably connected to the end of the adjusting rod 34. Specifically, a guide groove 400 is provided at the lower end of the movable rod 4, the end of the adjusting rod 34 is slidably connected to the guide groove 400, and the adjusting rod 34 can rotate relative to the guide groove 400. The movable plate 41 is slidably connected to the mounting seat 2 along the moving direction of the copper rod, the movable rod 4 is in movable contact with the movable plate 41. When the turntable 33 drives the adjusting rod 34 to slide, the adjusting rod 34 drives the movable rod 4 to rotate around its connection with the limiting shaft 401, so that the upper end or the lower end of the movable rod 4 pushes the movable plate 41 to slide relative to the mounting seat 2. The guide rod 42 is located at the rear side of the movable plate 41, the guide rod 42 is elastically connected to the movable plate 41 through an elastic member 44, and the elastic member 44 includes but is not limited to a spring and an elastic telescopic rod. The limiting insert block 43 is slidably connected to the guide rod 42 in the vertical direction. Limiting slots 2311 are provided on both of the first guide wheels 23. There are at least two limiting insert blocks 43. When the movable plate 41 moves backward, it pushes the limiting insert block 43 to insert into the limiting slots 2311 through the guide rod 42 and blocks the rotation of the first guide wheel 23.

[0039] One end of the first guide wheel 23 extends with a connecting shaft 231. The connecting shaft 231 is a part of the first guide wheel 23. The connecting shaft 231 is rotationally matched with the mounting seat 2. The mounting seat 2 is slidably assembled with a connecting block 232 in the vertical direction. The connecting shaft 231 is rotationally matched with the connecting block 232. When the distance between the two first guide wheels 23 changes according to the diameter of the copper rod, the two connecting blocks 232 slide synchronously in the vertical direction along with the two first guide wheels 23. To guide the sliding of the two connecting blocks 232 in the vertical direction, two limiting plates 233 can be fixed in the mounting seat 2. The two connecting blocks 232 are located between the two limiting plates 233 and slide in contact with the limiting plates 233. A vertical groove is formed on the limiting plate 233 adjacent to the guide rod 42. The limiting insertion block 43 passes through the groove on the limiting plate 233. A limiting slot 2311 is formed on the connecting shaft 231. A connecting groove 2321 is further provided on the connecting block 232. The limiting insertion block 43 extends into the connecting groove 2321. The limiting insertion block 43 slides synchronously in the vertical direction along with the connecting block 232. A spring is sleeved between the guide rod 42 and the connecting block 232 on the limiting insertion block 43. When the limiting insertion block 43 is inserted into the limiting slot 2311, the spring is compressed.

[0040] When the movable plate 41 is squeezed and slides relative to the mounting seat 2, it pushes the guide rod 42 to slide through the elastic member 44. The guide rod 42 further pushes the limiting insertion block 43 to slide along the direction close to the connecting shaft 231. Before the limiting component locks the first guide wheel 23, the first guide wheel 23 is in a rotating state. The limiting slot 2311 on the connecting shaft 231 may not be opposite to the limiting insertion block 43. When the limiting slot 2311 and the limiting insertion block 43 are misaligned, the limiting insertion block 43 abuts against the connecting shaft 231, and the elastic member 44 between the movable plate 41 and the guide rod 42 is squeezed. When the first guide wheel 23 rotates to make the limiting slot 2311 opposite to the limiting insertion block 43, the guide rod 42 and the limiting insertion block 43 slide backward under the elastic force of the elastic member 44. The limiting insertion block 43 is inserted into the limiting slot 2311 and blocks the rotation of the first guide wheel 23. After the limiting insertion block 43 is inserted into the limiting slot 2311, the spring sleeved on the limiting insertion block 43 is in a compressed and energy-storing state. After the movable plate 41 is reset, the limiting insertion block 43 disengages from the limiting slot 2311 under the elastic force of the spring and releases the limitation on the first guide wheel 23.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
