Description

Technical Field

[0001] The present invention relates to the technical field of copper busbar processing, and in particular to an automated copper busbar processing production line. Background Art

[0002] Copper busbars are long, rectangular or rounded copper conductors, used for conducting high currents. Their core applications include electrical engineering applications such as high- and low-voltage electrical equipment, power distribution equipment, and busbars, as well as ultra-high-current electrolytic smelting applications such as metal smelting and electrochemical plating.

[0003] Patent document with publication number CN117943840A discloses a copper busbar bending and forming mold, which includes a machine body, a core feeding module, a movable guide mechanism, and a bending and forming mechanism; the core feeding module passes through the machine body and is rotatably connected to the machine body, and the core feeding module is used to transport the copper busbar; the movable guide mechanism is arranged on the outer wall of the machine body, and the movable guide mechanism is used to move the bending and forming mechanism; the bending and forming mechanism is arranged at the output end of the movable guide mechanism.

[0004] In the prior art, copper busbars need to be bent vertically and horizontally during processing, so that they can adapt to complex installation environments and reduce space occupancy during installation. When the rectangular copper busbar is bent horizontally, the anisotropy of the bending stiffness due to the aspect ratio of the cross section makes it easy for cross-sectional distortion to occur at the horizontal bending portion of the rectangular copper busbar, thereby requiring support and position limiting of the upper and lower surfaces of the bending position. When the rectangular copper busbar is bent horizontally with position limiting, contact wear will occur between the rectangular copper busbar and the position limiting portions of the upper and lower surfaces, thereby increasing surface scratches and burrs at the position limiting portions and reducing the processing accuracy of the rectangular copper busbar.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] like Figures 1 to 12 The copper busbar automated processing production line shown includes a mounting plate 1 and further includes: Feed trough 2, feed trough 2 (such as Figure 5 As shown) is opened on the mounting plate 1, and a feeding assembly is provided inside the feeding trough 2; The bending base 3 is arranged below one end of the feeding trough 2. Two bending blocks 4 are fixedly installed on the top of the bending base 3. The adjacent ends of the two bending blocks 4 are both provided with a bending arc surface. A placement groove 5 is opened on the top of the bending base 3. Two rotating rings 6 are provided inside the placement groove 5 (such as Figure 8 As shown), the two rotating rings 6 are respectively coaxially arranged with the two curved arc surfaces (as shown Figure 12 shown); The movable plate 7 is fixedly connected between the two rotating rings 6, and two limit bars 8 are provided on the top of the movable plate 7; A bending assembly is provided on the bending base 3 and is used to drive the movable plate 7 to move in one direction; A limiting component is used to limit the rotation of the rotating ring 6 close to the moving direction of the movable plate 7 before the movable plate 7 moves. Pressing plate 9, which is arranged above the bending base 3 (such as Figure 3 As shown in FIG), the bottom of the pressing plate 9 is connected to a plurality of contact balls 10 in a rolling manner, and a bent top seat 11 is provided above the pressing plate 9 (as shown in FIG). Figure 9 As shown), an elastic yielding component is provided between the bent top seat 11 and the pressing plate 9; A lateral movable column 12 is provided on one side between the bending top seat 11 and the bending base 3. A vertical bending component is provided on the lateral movable column 12. A driving component is provided on the bending top seat 11, the bending base 3 and the lateral movable column 12. A truncation component is provided on the mounting plate 1. When the copper bar is bent, one end of the copper bar is passed through the feeding trough 2 and is moved and transported between the bending top seat 11 and the bending base 3 by the action of the feeding assembly. Then, the bending top seat 11 and the bending base 3 are driven by the driving assembly to move toward the upper and lower surfaces of the copper bar respectively. When the top of the bending base 3 contacts the lower surface of the copper bar, the movable plate 7 contacts the lower surface of the copper bar at the same time. The two bending stoppers 4 are respectively located on both sides of the copper bar. When the bending top seat 11 moves downward, it drives the pressing plate 9 to move downward, so that the contact ball 10 at the bottom of the pressing plate 9 rolls and contacts with the upper surface of the copper bar, thereby limiting the copper bar between the movable plate 7 and the contact ball 10. After the cam 7 is rotated and the cam 7 is rotated, the cam 7 is rotated and the cam 7 is rotated, so that the cam 7 moves along with the movable plate 7, and the movable plate 7 moves along with the movable plate 7. The lateral movable column 12 approaches the copper busbar through the action of the driving component, and bends the copper busbar in the vertical direction through the action of the vertical bending component. After the bending is completed, the copper busbar is cut off by the cutting component, thereby completing the bending process of a single copper busbar.

[0022] As a further embodiment of the present invention, the limiting assembly includes: Two limit shafts 13, both limit shafts 13 are slidably inserted on the bending base 3, the top ends of the two limit shafts 13 are respectively located inside the two rotating rings 6, the bottom ends of the two limit shafts 13 are fixedly connected to movable bars 14, and two limit pins 15 are slidably inserted on the movable bars 14, and the limit pins 15 are fixedly connected to the bending base 3, and a torsion hydraulic cylinder 16 is fixedly installed on the bending base 3. A guide plate 17 is fixedly connected to the piston shaft of the torsion hydraulic cylinder 16, and an inclined ring groove 18 is provided on the surface of the guide plate 17. An arc pin 19 is fixedly connected to the adjacent side of the two movable bars 14, and the arc ends of the two arc pins 19 are located inside the inclined ring groove 18; When the piston shaft of the torsional hydraulic cylinder 16 rotates, it drives the guide plate 17 to rotate synchronously, and through the guiding effect of the inclined ring groove 18 on the two arc pins 19, the two arc pins 19 are respectively located at the highest point and the lowest point inside the inclined ring groove 18. The arc pin 19 drives the movable bar 14 to move vertically along the sliding insertion point of the limit pin 15, and drives the corresponding limit shaft 13 to move synchronously. When one of the arc pins 19 is located at the highest point inside the inclined ring groove 18, the corresponding limit shaft 13 moves upward and completely fills the interior of the corresponding rotating ring 6. When the other arc pin 19 is located at the lowest point inside the inclined ring groove 18, the corresponding limit shaft 13 moves downward and completely disengages from the interior of the corresponding rotating ring 6, so that the two rotating rings 6 are respectively in a rotation limit state and a free movable state, so that the two rotating rings 6 can freely adjust the limit state according to the next horizontal bending direction of the copper busbar, so that the movable plate 7 can freely replace the rotation axis according to the bending direction of the copper busbar.

[0023] As a further embodiment of the present invention, the bending assembly comprises: A first connecting ring 20 is rotatably connected to the bending base 3. A first driving unit 21 is fixedly mounted on the first connecting ring 20. A strip groove 22 is formed on the first connecting ring 20. A circular pin 23 is fixedly connected to the movable plate 7, and one end of the circular pin 23 is located inside the strip groove 22; The first connecting ring 20 is driven by the first driving unit 21 to rotate along the rotating connection of the bent base 3, and the circular pin 23 is limited by the strip groove 22 on the first connecting ring 20, so that the movable plate 7 rotates along the rotating ring 6 close to the moving direction of the movable plate 7 as the axis, and the relative movement of the circular pin 23 inside the strip groove 22 ensures that the movable plate 7 can move normally when the first connecting ring 20 and the rotating ring 6 are not on the same axis.

[0024] As a further embodiment of the present invention, the movable plate 7 is provided with two movable grooves 24 (such as Figure 7 As shown), the two limit stoppers 8 are respectively slidably connected in the two movable grooves 24, and arc-shaped grooves 25 are provided on both sides of the movable groove 24. A polished rod 26 is fixedly connected to the interior of the arc-shaped groove 25. Sliders 27 are fixedly connected to both sides of the limit stopper 8. The slides 27 are located inside the corresponding arc-shaped grooves 25 and are slidably inserted on the corresponding polished rods 26. A first spring 28 is sleeved on the polished rod 26. The first spring 28 is fixedly connected between the corresponding slide 27 and the bottom surface of the arc-shaped groove 25. A guiding slope is provided on the side away from each other of the two stoppers; When the movable plate 7 moves horizontally along the corresponding rotating ring 6, the limit stopper 8 away from the moving direction pushes one side of the copper bar, so that the other side of the copper bar is squeezed with the corresponding bending stopper 4 and horizontally bent along the corresponding bending arc surface as the axis. At this time, the limit stopper 8 close to the moving direction of the movable plate 7 contacts and squeezes the corresponding bending stopper 4, and the guiding inclined surface on one side of the limit stopper 8 contacts and guides the bottom side of the bending stopper 4, so that the limit stopper 8 close to the moving direction of the movable plate 7 moves toward the inside of the movable groove 24, and at the same time, the two sides of the limit stopper 8 The slider 27 slides along the light rod 26 and squeezes the first spring 28 to produce compression deformation, so that the limit stop bar 8 that does not generate a driving force enters the corresponding movable groove 24 during the movement, preventing the contact between the limit stop bar 8 and the bending stop block 4 from affecting the horizontal bending angle, ensuring that the bending surface of the copper busbar is in full contact with the corresponding bending stop block 4 and reaches the maximum bending angle. When the movable plate 7 moves to the initial position, the compressed first spring 28 squeezes the slider 27 under the action of elastic extension, causing the limit stop bar 8 to move upward and return to the initial position.

[0025] As a further embodiment of the present invention, the elastic yielding component comprises: Multiple connecting pins 29, multiple connecting pins 29 are fixedly connected to the top of the pressing plate 9, the connecting pins 29 are slidably inserted on the bending top seat 11, and the connecting pins 29 are sleeved with a second spring 30, which is fixedly connected between the pressing plate 9 and the bending top seat 11 (such as Figure 9 shown); The bent top seat 11 is moved close to the copper busbar by the action of the driving assembly, so that the contact balls 10 at the bottom of the pressing plate 9 contact the upper surface of the copper busbar, and when the bent top seat 11 continues to move downward, the pressing plate 9 and the bent top seat 11 move relative to each other, so that the connecting pin 29 moves along the sliding joint of the bent top seat 11, and squeezes the second spring 30 to produce a compressive deformation, so that under the elastic extension action of the second spring 30 after compression, multiple contact balls 10 are elastically pressed on the upper surface of the copper busbar.

[0026] As a further embodiment of the present invention, a pressure sensor 31 is fixedly mounted on the bottom of the pressing plate 9. When the contact ball 10 contacts the upper surface of the copper busbar, the pressure sensor 31 is located between the two parallel sides of the bent stoppers 4. When the contact ball 10 contacts the upper surface of the copper busbar, the pressure detection end of the pressure sensor 31 contacts the upper surface of the copper busbar at the same time, and the contact pressure is detected in real time as the second spring 30 is compressed. When the pressure reaches the set value, the controller connected to the pressure sensor 31 controls the driving assembly on the bending top seat 11 to stop moving, and when the pressure sensor 31 contacts the copper busbar, the pressure sensor 31 is located between the two parallel sides of the bending block 4, so that when the bending block 4 is bent horizontally, the pressure sensor 31 is away from the bending movement of the copper busbar, reducing the relative movement between the copper busbar and the pressure sensor 31, and reducing the wear on the surface of the pressure sensor 31.

[0027] As a further embodiment of the present invention, the vertical bending assembly comprises: A rectangular groove 32 is provided at one end of the lateral movable column 12, and the sides of the rectangular groove 32 are all arc-shaped; The second connecting ring 33 is rotatably connected to the lateral movable column 12. The second driving unit 34 is fixedly installed on the second connecting ring 33. Two bending pins 35 are fixedly connected to the second connecting ring 33. The two bending pins 35 are respectively located above and below the side of the rectangular slot 32 away from the mounting plate 1 (as shown in FIG. Figure 3 shown); When the lateral movable column 12 approaches the copper busbar through the driving assembly, the copper busbar moves relatively from the side toward the inside of the rectangular groove 32, and is limited by the rectangular groove 32. Then, the second connecting ring 33 is driven by the second driving unit 34 to rotate along the rotating connection of the movable column, so that the lower bending pin 35 moves upward and the upper bending pin 35 moves downward, so that the copper busbar contacts and squeezes the arc edge corresponding to the rectangular groove 32, thereby bending the copper busbar upward and downward in the vertical direction.

[0028] As a further embodiment of the present invention, the drive assembly comprises: Three mounting frames 36 are fixedly connected to the mounting plate 1. The interior of the mounting frames 36 is slidably connected to a movable frame 37.

The interior of the mounting frames 36 is rotatably connected to a lead screw 38. The movable frame 37 is threadedly connected to the corresponding lead screw 38. A first motor 39 is fixedly installed on the mounting frames 36. The output shaft of the first motor 39 is fixedly connected to one end of the corresponding lead screw 38 (such as Figure 2 shown); The output shaft of the first motor 39 rotates to drive the corresponding lead screw 38 to rotate, and the lead screw 38 is threadedly connected to the corresponding movable frame 37, so that the movable frame 37 moves along the sliding connection, thereby causing the bending top seat 11, the bending base 3 and the lateral movable column 12 to be displaced respectively by the corresponding first motor 39.

[0029] As a further embodiment of the present invention, the feeding assembly comprises: The conveying frame 40 is fixedly connected to the inside of the feeding trough 2. Two rotating shafts 41 are connected to the conveying frame 40 for vertical rotation. Contact rollers 42 are fixedly connected to the rotating shafts 41. One end of each rotating shaft 41 is fixedly connected to a gear 43. The two gears 43 are meshed with each other. A plurality of auxiliary rollers 44 are rotatably connected to both sides of the conveying frame 40.

The two contact rollers 42 are in contact with the upper and lower surfaces of the copper bar respectively, and the corresponding rotating shaft 41 is driven to rotate by the output shaft of the second motor 45. The two gears 43 are engaged, so that the two rotating shafts 41 drive the corresponding contact rollers 42 to move in opposite directions. The contact friction between the contact rollers 42 and the copper bar is used to transport the copper bar toward the feeding nozzle 46, and one end of the copper bar passes through the inside of the feeding nozzle 46 and is moved and transported. During the movement of the copper bar, the auxiliary rollers 44 on both sides contact the side surfaces of the copper bar and rotate in coordination to prevent the copper bar from deflecting during the movement.

During cutting, the top surface of the second U-shaped bracket 48 supports the lower surface of the copper busbar, thereby reducing the deformation of the copper busbar caused by the cutting force.

[0031] Working principle of the present invention: When the copper bar is bent, one end of the copper bar is passed through the feeding trough 2 and is moved and transported between the bending top seat 11 and the bending base 3 by the action of the feeding assembly. Then, the bending top seat 11 and the bending base 3 are driven by the driving assembly to move toward the upper and lower surfaces of the copper bar respectively. When the top of the bending base 3 contacts the lower surface of the copper bar, the movable plate 7 contacts the lower surface of the copper bar at the same time. The two bending stoppers 4 are respectively located on both sides of the copper bar. When the bending top seat 11 moves downward, it drives the pressing plate 9 to move downward, so that the contact ball 10 at the bottom of the pressing plate 9 rolls and contacts with the upper surface of the copper bar, thereby limiting the copper bar between the movable plate 7 and the contact ball 10. After the cam 7 is rotated and the cam 7 is rotated, the cam 7 is rotated and the cam 7 is rotated, so that the cam 7 moves along with the movable plate 7, and the movable plate 7 moves along with the movable plate 7. The lateral movable column 12 approaches the copper busbar through the action of the driving component, and bends the copper busbar in the vertical direction through the action of the vertical bending component. After the bending is completed, the copper busbar is cut off by the cutting component, thereby completing the bending process of a single copper busbar.
