[0002] As a highly efficient conductive material, hard copper busbar is widely used in many fields due to its high conductivity, corrosion resistance and high mechanical strength. In the electrical field, hard copper busbar is used to connect electrical equipment such as bus ducts, switch cabinets, cable trays, etc. to ensure stable current transmission. In the field of new energy, hard copper busbar has become an ideal choice for solar energy, wind energy and other power generation systems, and is widely used in the conductive connection of various equipment in the industrial manufacturing field. Its excellent performance provides strong support for the development of modern industry.

[0003] At present, according to the site layout and installation requirements, the hard copper busbar must adapt to various complex installation environments and space limitations and be flexibly arranged. The hard copper busbar is bent to form a specific shape and structure to optimize the distribution of current in the conductor.

[0004] After cold bending, the existing hard copper busbars are prone to deformation during use due to insufficient stress release, affecting the stability of the power system operation. In addition, they rely on manual feeding, bending and discharging, resulting in low efficiency and prone to errors. Therefore, a hard copper busbar processing and bending device is proposed.

[0048] When in use, the servo motor 617 drives the screw 61 to rotate, so that the screw 61 drives the internal threaded sleeve 63 to move under the movable groove 12. At the same time, during the movement of the internal threaded sleeve 63, the gear 69 at the bottom of the internal threaded sleeve 63 will generate a rotational force based on the engagement of the rack 64, and drive the spiral blade 68 to rotate.

[0054] When in use, the servo motor 617 drives the screw rod 61 to move the internal threaded sleeve 63 toward the mold assembly 4. During this period, the lower connecting arm 624 below the internal threaded sleeve 63 will push the support seat 620 into the bottom of the mold assembly 4, so that the support roller 621 on the support seat 620 supports the bottom of the mold assembly 4.

[0056] When in use, the support seat 620 is based on the movement of the internal threaded sleeve 63, and the support roller 621 on the support seat 620 will push up and support the lower die seat 41 in a hanging state, so that the lower die seat 41 and the upper die seat 43 form a state of vertical parallelism, and the hard copper bar blank entering the mold assembly 4 is supported by the lower die 42, and then the upper die seat 43 is pushed down by the cylinder 46, so that the upper die seat 43 presses down the hard copper bar blank on the lower die 42, so that the copper bar is bent, and when the servo motor 617 rotates and the screw rod 61 drives the internal threaded sleeve 63 to return, the support seat 620 simultaneously leaves the support for the lower die seat 41, the lower die seat 41 resumes hanging, and the hard copper bar after pressing and bending falls from the lower die 42 into the heat treatment assembly 5.

[0057] In order to heat the hard copper bar to release the stress caused by pressing and bending the hard copper bar, for example, Figure 1-11 As shown, the present invention also includes that the heat treatment component 5 includes a quartz box 51 and a high-frequency induction coil 54, the quartz box 51 is provided with a feed port 52, the bottom of the quartz box 51 is provided with a feed port 53, one end of the pull-out plate 623 is inserted into the feed port 53, one end of the pull-out plate 623 is provided with a through port 627 for unloading hard copper bars, the bottom of the discharge end of the workbench 1 is provided with an inclined unloading port 15 connected to the feed port 53, the feed port 53 is connected to the feed port 52, the high-frequency induction coil 54 is arranged at the bottom of the quartz box 51, and the feed port 53 is located in the middle of the high-frequency induction coil 54.

[0058] The pull-out plate 623 is made of quartz material.

[0059] When in use, the quartz box 51 provides a heating environment for the hard copper bar, and the high-frequency induction coil 54 heats the hard copper bar that falls to the bottom of the quartz box 51, so that the stress caused by the compression and bending of the hard copper bar is released until the next operation of the drive component 6. The servo motor 617 in the drive component 6 drives the screw rod 61 again, so that the lower connecting arm 624 at the bottom of the internal threaded sleeve 63 drives the pull-out plate 623 to further insert into the quartz box 51, and the through opening 627 of the pull-out plate 623 will move into the quartz box 51 and overlap with the feed port 53, so that the hard copper bar after heating treatment falls into the inclined discharge port 15 through the feed port 53 and is discharged to the outside from the inclined discharge port 15, thereby realizing automatic discharge.

[0060] When the present invention is in use, the hard copper bar blanks that need to be bent are placed in the storage box 3. Based on the discharge port 32 at the bottom of the storage box 3, the hard copper bar blanks at the bottom of the storage box 3 will fall into the guide groove 11. When the storage box 3 needs to be replaced, the output end of the electric cylinder 14 is recovered, so that the storage box 3 between the ferrules 13 loses its limit, and then the new storage box 3 is inserted between the ferrules 13. At the same time, the original storage box 3 will be ejected, and then the output end of the electric cylinder 14 is output again, and the positioning socket 34 of the newly entered storage box 3 is inserted to fix the storage box 3. During the bending process, the servo motor 617 drives the screw rod 61 to rotate, so that the screw rod 61 drives the internal thread sleeve 63 to move under the movable groove 12. At the same time as the internal thread sleeve 63 moves When the gear 69 below the internal threaded sleeve 63 is meshed with the rack 64, the spiral blade 68 is driven to rotate forward, so that negative pressure is generated at the end of the air cylinder 67 close to the gear 69, so that negative pressure is formed in the inner sleeve 611 and the top sleeve 613, so that the air inlet 66 on the top sleeve 613 draws air upward. At the same time, before the top sleeve 613 enters the bottom of the storage box 3, the high-pressure air at the end of the air cylinder 67 away from the gear 69 will be discharged through the metal shaping hose 616, and the air nozzle on the metal shaping hose 616 will be sprayed to the surface of the mold assembly 4, so that the surface of the mold assembly 4 is cleaned before operation, which can effectively avoid the influence of impurities on the bending quality of the hard copper bar. When the top sleeve 613 in the moving groove 12 passes under the storage box 3, the air inlet with the sealing ring 614 The hole 66 will grab and suck the hard copper bar blank retained in the guide groove 11 below the storage box 3, and drive it to move to the discharge end of the guide groove 11, so that the hard copper bar enters the mold assembly 4. During this period, when the hard copper bar is grabbed and sucked and moved toward the mold assembly 4, the support seat 620 contacts the lower mold seat 41 based on the movement of the internal threaded sleeve 63, and pushes the lower mold seat 41. The support roller 621 on the support seat 620 pushes and supports the lower mold seat 41 in a hanging state, so that the lower mold seat 41 and the upper mold seat 43 form a state of vertical parallelism, and the hard copper bar blank entering the mold assembly 4 is supported by the lower die 42, and the upper die seat 43 is pushed down by the cylinder 46, so that the upper die seat 43 presses down the hard copper bar blank on the lower die 42, so that the copper bar is bent. When the servo motor 617 rotates, so that the screw rod 61 drives the internal threaded sleeve 63 to return to its original position, the support seat 620 simultaneously leaves the support for the lower die seat 41, and the lower die seat 41 resumes to hang down, and the hard copper bar after pressing and bending is discharged from the lower die 42 and enters the quartz box 51 through the feeding port 53. At the same time, the pull-out plate 623 is also retracted, and supports the hard copper bar in the quartz box 51, and is heated by the high-frequency induction coil 54 to the hard copper bar at the bottom of the quartz box 51, so that the stress generated by the pressing and bending of the hard copper bar is released until the next operation of the drive assembly 6. In the drive assembly 6, the servo motor 617 drives the screw rod 61 again, so that the lower connecting arm 624 at the bottom of the internal threaded sleeve 63 drives the pull-out plate 623 to further insert into the quartz box 51.The opening 627 of the pull plate 623 will move into the quartz box 51 and overlap with the feed port 53, so that the hard copper bar after heating treatment will fall into the inclined discharge port 15 through the feed port 53 and be discharged from the inclined discharge port 15 to the outside, thereby realizing automatic discharge and completing the automatic feeding, discharge and heat treatment of the hard copper bar.
