Description

Technical Field

[0001] This utility model relates to the technical field of copper rod processing equipment, specifically to a copper rod flattening, punching, and bending machine. Background Technology

[0002] Copper rod processing refers to the reprocessing of cylindrical copper rods. This typically involves altering their shape, size, precision, or surface condition through cutting, plastic deformation, joining, or other physical means to manufacture parts or structural components that meet specific requirements. Common processing methods include drilling, bending, and stamping. The primary purpose is to utilize copper's excellent electrical and thermal conductivity, corrosion resistance, and ease of machining to produce precision components for electrical connectors, heat exchanger parts, valves, bearings, decorative parts, handicrafts, and various mechanical devices.

[0003] Current processing equipment typically includes clamping, bending, and flattening / punching units, but these are generally arranged linearly. The bending unit, located between the clamping and flattening / punching units, may cause instability in the copper rod clamping. For example, a CNC copper rod processing device (publication number CN211191633U) includes: a frame with a copper rod rotating clamping structure, and a copper rod bending assembly at one end of the frame, with the bending hole of the bending assembly facing the clamping opening of the rotating clamping structure; a gantry frame with a mold frame inside, and multiple processing stations on the mold frame, where the top of the online processing station is aligned with the striking assembly, and one side is aligned with the bending hole of the copper rod bending assembly; the gantry frame can move away from or close to the copper rod bending assembly, and all drive structures are connected to the control system. This CNC copper rod processing device integrates copper rod bending, flattening, punching, chamfering, and shearing processes, improving work efficiency, reducing labor intensity, and simultaneously improving the processing quality of the busbar.

[0004] Therefore, a copper rod flattening, punching, and bending machine is proposed to solve the above problems. Utility Model Content

[0017] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:

[0018] 1. This utility model integrates the feeding unit, flattening and punching unit, and bending unit on the frame, making the overall structure more compact and reducing the space occupied by the device. The flattening and punching unit and the bending unit are located on both sides of the frame, and the flattening and punching unit is closer to the feeding unit. This reduces the distance of the feeding unit support when flattening and punching copper rods, resulting in better stability, avoiding material waste, and improving economy.

[0019] 2. This utility model, by setting up a clamping assembly, has a clamping end that can be detachably set with a clamping mouth on the clamping head. When clamping the copper rod, the clamping mouth can come close to each other, and when releasing the copper rod, the return spring makes the clamping mouth move away from each other. It can adapt to the clamping needs of copper rods of various diameters, and has better practicality and stability.

[0020] 3. This utility model incorporates balancing components to coordinate with the lifting components in adjusting the processing height of the copper rod. The balancing components are located on both sides of the feeding seat, at both the front and rear ends, to prevent overall bending caused by the descent of the copper rod's axis during flattening processing. It also avoids the problem of the feeding seat shifting due to the force points of the lifting and balancing components being located at different positions along the length of the copper rod, which could lead to the copper rod's axis not remaining horizontal. This improves processing accuracy, and the use of only two balancing components enhances economic efficiency. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-10 As shown, this utility model provides a technical solution:

[0035] A copper rod flattening, punching, and bending machine includes a frame 1, which is located at one end of a feeding plate 11. The feeding plate 11 serves as a platform for placing copper rods, and several copper rods are placed on the feeding plate 1. A feeding unit is installed on the frame 1. A gantry frame 2 is installed at the end of the frame 1 away from the feeding plate 11 along the feeding direction of the feeding unit, i.e., the feeding direction of the copper rods. A flattening and punching unit 8 is installed on the gantry frame 2. A bending unit 9 is installed on the side of the frame 1 away from the feeding unit of the gantry frame 2. The flattening and punching unit 8 and the bending unit 9 are located on opposite sides of the frame 1. The bending and flattening punching processes are performed on the left and right sides of the frame 1 respectively, so as to avoid the flattening punching unit 8 affecting the bending operation; the feeding unit includes a feeding seat 10, which is set on the moving component 5 through the lifting component 3 and the balancing component 4. The moving component 5 is set on the frame 1 and is used to drive the copper rod to move and change position. The two ends of the feeding seat 10 are respectively set with a clamping component 6 and a rotating component 7, and the rotating component 7 is connected to the clamping component 6 to drive the clamping component 6 to rotate, so as to drive the copper rod to rotate and meet the bending needs of the copper rod in different directions.

[0036] In an optional embodiment, the moving component 5 includes a first guide rail 501, which is disposed on the frame 1 and has at least two parallel rails. The length direction of the first guide rail 501 is parallel to the direction of copper rod feeding. A base plate 502 is slidably disposed on the first guide rail 501. A first lead screw 503 is threadedly connected to the base plate 502. The first lead screw 503 is rotatably disposed on the frame 1, and the axis of the first lead screw 503 is parallel to the length direction of the first guide rail 501. One end of the first lead screw 503 is connected to the output end of a first power component 504. The first power component 504 is a motor and is disposed on the frame 1. First limiting components 505 are disposed on the frame 1 at both ends of the first guide rail 501 to prevent the base plate 502 from slipping off the first guide rail 501.

[0037] A second guide rail 506 is provided on the base plate 502. At least two parallel guide rails are provided on the second guide rail 506. The length direction of the second guide rail 506 is perpendicular to the length direction of the first guide rail 501. A seat plate 507 is slidably provided on the second guide rail 506. The seat plate 507 is threadedly connected to a second lead screw 508. The second lead screw 508 is rotatably provided on the base plate 502, and the axis of the second lead screw 508 is parallel to the length direction of the second guide rail 506. One end of the second lead screw 508 is connected to the output end of a second power component 509. The second power component 509 is a motor and is provided on the base plate 502. Second limiting components 510 are provided on the base plate 502 at both ends of the second guide rail 506 to prevent the seat plate 507 from slipping off the second guide rail 506.

[0038] In an optional embodiment, the first limiting member 505 and the second limiting member 510 have the same structure, both including a limiting seat and a limiting block. The limiting block is set on the limiting seat by a stud. The limiting block is made of rubber to reduce collision impact and extend the service life of the device. Preferably, a pressure sensor is provided on the limiting block to detect the pressure on the limiting block. The pressure sensor is connected to the control system. The control system is connected to the first power member 504 and the second power member 509. The detection threshold of the pressure sensor can be set. When the threshold is reached, the control system controls the first power member 504 or the second power member 509 to stop, which improves safety.

[0039] In an optional embodiment, the lifting assembly 3 includes a lifting guide shaft 301 and a lifting power component 303. Multiple lifting guide shafts 301 are mounted on the seat plate 507. The axis of the lifting guide shaft 301 is perpendicular to both the axis of the first lead screw 503 and the axis of the second lead screw 508. A sliding block 302 is slidably mounted on the lifting guide shaft 301 and is located on the side of the feeding seat 10, allowing the feeding seat 10 to move up and down along the lifting guide shaft 301. The lifting power component 303 is a pneumatic cylinder or a hydraulic cylinder. The lifting power component 303 is set on the seat plate 507 on both sides of the feeding seat 10, and the axis of the output end of the lifting power component 303 is parallel to the axis of the lifting guide shaft 301. The output end of the lifting power component 303 is coaxially set with the adjusting bolt 304, which passes through the limiting plate 305. Nuts are threadedly connected to the adjusting bolts 304 on both the upper and lower sides of the limiting plate 305. The nuts can limit the position of the limiting plate 305 after adjusting the height position of the limiting plate 305 relative to the adjusting bolt 304. The limiting plate 305 is set on the feeding seat 10.

[0040] In an optional embodiment, the balancing assembly 4 includes a balancing power component 401, which is a cylinder or hydraulic cylinder. Two balancing power components 401 are respectively disposed on the seat plates 507 on both sides of the feeding seat 10. The axis of the output end of each balancing power component 401 is parallel to the axis of the lifting guide shaft 301. The output end of each balancing power component 401 is connected to the feeding seat 10 via a straight plate 402. The output end of each balancing power component 401 is used to continuously pull the feeding seat 10 downwards. One balancing power component 401 is located at the front end of the seat plate 507, and the other is located at the rear end of the seat plate 507, i.e., at the lifting power component 301. To avoid uneven force on the feeder seat 10 in the front-to-back direction when they are on the same side, which could cause the feeder seat 10 to tend to flip back and forth, although there are lifting guide shafts 301 and sliding blocks 302 for limiting, the force on the feeder seat 10 may also cause the connection between the sliding block 302 and the feeder seat 10 to become unstable. Therefore, it is necessary to set balancing power components 401 on both sides of the lifting power component 303, and the downward pulling force of the balancing power components 401 on both sides must be consistent. The maximum output force of the lifting power component 303 is greater than the pulling force of the balancing power component 401, so that the feeder seat 10 can move upward.

[0041] The bending height is determined by the height of the bottom of the feeding seat 10. When bending is required, the lifting power component 303 does not need to output force, or the output force of the lifting power component 303 is less than the pulling force of the balancing power component 401. The feeding seat 10 is positioned at the bottom by the pulling force of the balancing power component 401, and the bottom of the feeding seat 10 is taken as the bending height. When flattening is required, the lifting power component 303 outputs a thrust, and the thrust is greater than the pulling force of the balancing power component 401, causing the feeding seat 10 to rise. After reaching the processing height, the lifting power component 303 maintains the same thrust as the pulling force of the balancing power component 401, keeping the feeding seat 10 stationary. When the copper rod is flattened, the copper rod is subjected to vertical force, and the axial height of the copper rod will decrease, causing the overall height of the copper rod to decrease. If the balancing component 4 is not used to balance the force, the copper rod is prone to bending at the front and back, affecting the processing quality of the copper rod.

[0042] In an optional embodiment, the lifting assembly 3 further includes a bottom support bolt 306, which passes through the front and rear ends of the seat plate 507 located below the feeding seat 10. The bottom support bolt 306 is threadedly connected to the seat plate 507, and the axis of the bottom support bolt 306 is parallel to the axis of the lifting guide shaft 301. The top tip of the bottom support bolt 306 is used to contact the bottom of the feeding seat 10 and can support the feeding seat 10. The height of the top tip of the bottom support bolt 306 can be adjusted to adjust the height of the feeding seat 10 at the bottom position to adapt to the processing needs of copper rods of different diameters.

[0043] In an optional embodiment, the clamping assembly 6 includes an inner sleeve 601, which is rotatably mounted on the feed seat 10 and has its axis parallel to the copper rod feeding direction. An outer sleeve 602 is coaxially mounted on the outer side of the inner sleeve 601 near the flattening and punching unit 8 of the feed seat 10, and the outer sleeve 602 is slidably connected to the inner sleeve 601. A guide key 603 is provided on the outer side of the inner sleeve 601, and a keyway 604 is provided on the side wall of the outer sleeve 602 corresponding to the guide key 603. The length direction of the keyway 604 is parallel to the axis of the outer sleeve 602, and the guide key 603 is slidably mounted in the keyway 604 so that the inner sleeve 601 can drive the outer sleeve 602 to rotate without affecting the sliding of the outer sleeve 602.

[0044] In an optional embodiment, a sleeve base 605 is coaxially disposed at one end of the inner sleeve 601 near the flattening and punching unit 8. Three chucks 606 are evenly disposed circumferentially at the end of the sleeve base 605 away from the inner sleeve 601. The chucks 606 are rotatably disposed on the sleeve base 605, and the axis of rotation of the chucks 606 is perpendicular to the axis of the inner sleeve 601. A reset sleeve 607 is also coaxially disposed at the middle of the end of the sleeve base 605 away from the inner sleeve 601. Several reset springs 608 are disposed on the outer side of the reset sleeve 607 corresponding to the chucks 606. The two ends of the reset springs 608 contact the reset sleeve 607 and the chucks 606 respectively, and are used to push the chucks 606 away from the reset sleeve 607. A clamping mouth 609 is detachably disposed on each of the chucks 606. The clamping mouth 609 can cooperate to clamp the copper rod. The side of the chuck 606 away from the reset sleeve 607 is set as an inclined surface 610. The inclined surface 610 is inclined towards the inner sleeve 601 to contact the inner wall of the connecting sleeve 611. The connecting sleeve 611 is slidably fitted on the outer side of the sleeve seat 605. The connecting sleeve 611 is set at one end of the outer sleeve 602. The other end of the outer sleeve 602 is coaxially connected to the sleeve 611 ring. The sleeve ring 612 has a circumferential groove 613. A roller 614 is slidably set in the groove 613. The axis of the roller 614 is perpendicular to the axis of the outer sleeve 602, and the roller 614 can drive the sleeve ring 612 to move. The roller 614 is set on the swing arm frame 615. One end of the swing arm frame 615 is rotatably connected to the pressure cover 616. The pressure cover 616 is set on the feeding seat 10. The other end of the swing arm frame 615 is rotatably connected to the output end of the clamping power component 617. The clamping power component 617 is a cylinder or hydraulic cylinder and is rotatably set on the feeding seat 10 to drive the swing arm frame 615 to move.

[0045] In an optional embodiment, the rotating assembly 7 includes a rotating power component 701, which is a motor and is mounted on the feeding seat 10 via a mounting plate 702. The output end of the rotating power component 701 is connected to the inner sleeve 601 via a transmission assembly 703 and can drive the inner sleeve 601 to rotate, thereby driving the copper rod held by the clamping assembly 6 to rotate.

[0046] In an optional embodiment, the transmission assembly 703 includes a main synchronous pulley and a driven synchronous pulley. The main synchronous pulley is coaxially disposed at the output end of the rotating power component 701, and the driven synchronous pulley is coaxially disposed on the outside of the inner sleeve 601. The main synchronous pulley and the driven synchronous pulley are connected by a synchronous belt drive. Preferably, the outside of the synchronous belt contacts a tensioning wheel, which is disposed on the mounting plate 702 to improve the stability of the transmission.

[0047] In an optional embodiment, the flattening and punching unit 8 includes a lateral moving force member 801, which is a cylinder or hydraulic cylinder, and is located on the side of the gantry 2 away from the bending unit 9.

[0049] Working principle: The copper rod on the feeding plate 11 is inserted through one end of the inner sleeve and passes through the inner sleeve. The clamping power component 617 is activated, which drives the outer sleeve to slide so that the clamping mouth 609 clamps the copper rod. The moving component 5 drives the copper rod to move. When the front end of the copper rod reaches the flattening die 805, it is flattened first. Then the lower die frame 802 and the copper rod are moved so that the copper rod is located at the punching die 806. Then punching and cutting are performed. Punching and cutting are completed simultaneously, which is the existing technology in this field. Then the copper rod is moved to the bending unit 9. The bending unit 9, together with the rotating component 7, completes the bending of the copper rod. After the copper rod is bent to the required shape, the moving component 5 drives the copper rod to move to the flattening die 805 again to flatten the rear end of the bent shape of the copper rod. Then the copper rod is moved to the punching die 806 for punching and cutting, completing the processing of one workpiece.
