Description

Technical Field

[0001] This invention relates to the field of spiral duct U-shaped clamp processing technology, and in particular to an automatic processing equipment for spiral duct U-shaped clamps. Background Technology

[0002] U-shaped clamps for spiral ducts are accessories used to connect and fix spiral ducts. They are usually made of galvanized steel sheet and have a U-shaped structure that can fit the outer arc of the spiral duct. By using bolts or other connectors through the mounting ears at both ends, the two sections of duct or the duct can be fastened to other components, which can play a role in fixing and sealing, ensuring the stable operation of the duct system. They are widely used in ventilation, air conditioning and other duct engineering.

[0003] In the bending and forming process of U-shaped clamps, manual bending is currently the most common method. However, due to the difficulty in precisely controlling the force applied manually and the lack of a standardized positioning benchmark, the angle deviation of the bent U-shaped clamp can reach ±3°, and the maximum curvature error can reach 2mm. This not only reduces the fit accuracy between the clamp and the spiral duct, increasing installation difficulty, but also results in a rework rate of up to 15% for defective products, severely impacting the overall production schedule.

[0020] The beneficial effects of the automatic processing equipment for U-shaped clamps of spiral ducts provided by the present invention are as follows:

[0021] (1) Bending unit: After the processed steel plate falls onto the placement plate, the first hydraulic device will drive the first telescopic rod to extend, thereby pushing the placement plate to rotate to a vertical state. Then the first motor will drive the first reciprocating screw to rotate, thereby moving the first moving block and moving the mold plate and mold assembly into the placement plate and making the mold unit enter the notch of the placement plate. Thus, as the placement plate and mold assembly are squeezed, the steel plate initially fits against the mold block.

[0022] (2) Bending unit: During the long-term contact and friction between the bending die and the galvanized steel plate, the zinc layer on the galvanized steel plate will adhere to the bending die, which will cause the U-shaped clamp after bending to deviate in dimensional accuracy and fail to meet the design requirements. Therefore, during the process without processing, the second telescopic rod will extend and drive the scraping ring to contact the die block, thereby removing the zinc layer adhering to the die block.

[0023] (3) Mold assembly: Since the stress at the bending point will cause the steel plate to spring back after bending, the mold unit will preset the excessive bending angle according to the steel plate of different thicknesses. During the pressing process of the pressing assembly pressing the steel plate, the first micro motor will drive the large gear to rotate at a certain angle. The rotation of the meshing small gear will cause the first rotating shaft and the angle plate to rotate, thereby causing the mounting ears of the spiral duct U-shaped clamp to bend excessively.

[0024] (4) Pressing assembly: During the pressing assembly process, the third telescopic rod will extend and drive the side plate and the placement box to approach the mold assembly. Then, the energized rubidium magnet assembly will generate a strong magnetic force, thereby attracting the rubidium magnet plate and driving the pressing arc plate and the inclined plate to press the steel plate. Before pressing, the second micro motor will also drive the inclined plate to rotate to an angle that matches the angle plate. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the further embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] like Figure 1 As shown, an automatic processing device for U-shaped clamps of spiral ducts includes: a base plate 1, an operating table 2 on the top of the base plate 1, and further includes:

[0041] The cutting unit 3 is used to stamp and cut the original steel plate; the spraying unit 4 is used to clean and lubricate the steel plate after cutting; and the bending unit 5 is used to bend and shape the steel plate.

[0042] In the operation of this invention, the steel plate to be processed is first placed into the cutting unit 3 and cut into a specific shape and size. Then the steel plate enters the spraying unit 4 for cleaning and lubrication, and finally falls into the bending unit 5 for shaping and pressing, thereby processing it into a spiral duct U-shaped clamp.

[0043] like Figures 2-4 As shown, the bending unit 5 includes a bending table 51, and a mold mechanism 55 is provided at one end of the bending table 51.

[0044] like Figure 5 As shown, the mold mechanism 55 includes symmetrically arranged second support plates 551. A first motor 552 is provided on the outer surface of one side of the second support plate 551. A first reciprocating screw 554 is provided at the output end of the first motor 552. A first moving block 553 is threadedly connected to the outer surface of the first reciprocating screw 554. A mold plate 557 is provided on the outer surface of the first moving block 553. A mold assembly 555 is provided at the center of the mold plate 557. Inner grooves 558 are symmetrically arranged at the upper and lower ends of the mold plate 557. A pressing assembly 556 is provided on the outer surface of the inner grooves 558.

[0045] After the processed steel plate falls onto the placement plate 53, the first hydraulic device 56 drives the first telescopic rod 57 to extend, thereby pushing the placement plate 53 to rotate to a vertical state. Then, the first motor 552 drives the first reciprocating screw 554 to rotate, thereby moving the first moving block 553 and moving the mold plate 557 and mold assembly 555 into the placement plate 53, and causing the mold unit to enter the notch 54 of the placement plate 53. Thus, with the compression of the placement plate 53 and the mold assembly 555, the steel plate initially adheres to the mold block 5552.

[0046] like Figures 6-7 As shown, the mold assembly 555 includes a fixing block 5551, a mold block 5552 is provided at the end of the fixing block 5551 away from the mold plate 557, an inner cavity 5553 is provided on the mold block 5552, an inner plate 5554 is symmetrically arranged in the inner cavity 5553, a first micro motor 5555 is provided on the outer surface of the inner plate 5554, a large gear 5556 is provided at the output end of the first micro motor 5555, a first rotating shaft 5557 is also provided at the upper and lower ends of the inner cavity 5553, an angle plate 5558 is welded to the outer surface of the first rotating shaft 5557, a small gear 5559 that meshes with the large gear 5556 is provided on the side of the first rotating shaft 5557 near the large gear 5556, and an energized rubidium magnet assembly 55510 is provided at the end of the inner cavity 5553 near the fixing block 5551.

[0047] Because the stress at the bend will cause the steel plate to spring back after bending, the mold unit will preset the excessive bending angle according to the different thicknesses of the steel plate. During the pressing process of the pressing component 556 pressing the steel plate, the first micro motor 5555 will drive the large gear 5556 to rotate at a certain angle. The rotation of the meshing small gear 5559 will cause the first rotating shaft 5557 and the angle plate 5558 to rotate, thereby causing the mounting ears of the spiral duct U-shaped clamp to bend excessively.

[0048] The bending table 51 is placed on top of the base plate 1. The outer surface of the second support plate 551 is fixedly connected to the outer surface of the bending table 51, and the outer surface of the fixing block 5551 is fixedly connected to the center of the mold plate 557.

[0049] like Figures 8-9 As shown, the pressing assembly 556 includes a symmetrically arranged third telescopic rod 5561. A support rod 5562 is symmetrically arranged at the output end of the third telescopic rod 5561. A side plate 5563 is provided at the end of the support rod 5562 away from the third telescopic rod 5561. A placement box 5564 is provided at one end of the side plate 5563. A second rotating shaft 5565 is provided inside the placement box 5564. A pressing arc plate 5566 that matches the arc angle of the mold block 5552 is welded to the outer surface of the second rotating shaft 5565. A second micro motor 5568 is provided at the end of the pressing arc plate 5566 away from the second rotating shaft 5565. An inclined plate 5569 is provided at the output end of the second micro motor 5568. A rubidium magnet plate 5567 is provided at the end of the pressing arc plate 5566 near the inner side of the placement box 5564.

[0050] During the pressing process of component 556, the third telescopic rod 5561 extends and drives the side plate 5563 and the placement box 5564 to approach the mold component 555. Then, the energized neodymium magnet component 55510 generates a strong magnetic force, which attracts the neodymium magnet plate 5567 and drives the pressing arc plate 5566 and the tilting plate 5569 to press the steel plate. Before pressing, the second micro motor 5568 also drives the tilting plate to rotate to an angle that matches the angle plate 5558.

[0051] The third telescopic rod 5561 is installed on the inner wall of the mold plate 557. The energized rubidium magnet assembly 55510 attracts the rubidium magnet plate 5567 after being energized.

[0052] The bending unit 5 also includes a support block 52. A placement plate 53 is rotatably connected to the outer surface of the support block 52. A notch 54 is provided in the center of the placement plate 53. A first hydraulic device 56 is provided near the placement plate 53 on the bending table 51. A first telescopic rod 57 is symmetrically arranged on the first hydraulic device 56. A stop end 58 is provided at the output end of the first telescopic rod 57. A second telescopic rod 59 is provided at one end of the bending table 51 near the mold mechanism 55. A first support plate 510 is fixedly connected to the output end of the second telescopic rod 59. A scraping ring 511 is provided on the outer surface of the first support plate 510. The scraping ring 511 is adapted to the mold block 5552.

[0053] During the long-term contact and friction between the bending die and the galvanized steel sheet, the zinc layer on the galvanized steel sheet may adhere to the bending die, which will cause the dimensional accuracy of the U-shaped clamp after bending to deviate and fail to meet the design requirements. Therefore, when no processing is performed, the second telescopic rod 59 will extend and drive the scraping ring 511 to contact the die block 5552, thereby removing the zinc layer adhering to the die block 5552.

[0054] The bottom of the support block 52 is fixedly connected to the inner wall of the bending table 51. The width of the notch 54 is shorter than the width of the steel plate used for processing, and the length of the notch 54 is longer than the length of the steel plate used for processing. The mold assembly 555 can pass through the notch 54.

[0055] like Figures 10-11 As shown, the cutting unit 3 includes a cutting box 31. The inner cavity 5553 of the cutting box 31 is provided with a slide rail 32. The outer surface of the cutting box 31 is provided with an insertion plate 33. The two ends of the cutting box 31 are symmetrically provided with outer plates 34. The outer plates 34 are provided with a second hydraulic device 35. The second hydraulic device 35 is provided with a fourth telescopic rod 36. The output end of the fourth telescopic rod 36 is fixedly connected to a push plate 37. The top of the cutting box 31 is provided with a third hydraulic device 38. The bottom of the third hydraulic device 38 is symmetrically provided with a fifth telescopic rod 39. The output end of the fifth telescopic rod 39 is fixedly connected to a third support plate 310. The bottom of the third support plate 310 on one side is provided with a pressing plate 311, and the bottom of the third support plate 310 on the other side is provided with a cutting plate 312.

[0056] After the steel plate is placed into the placement plate 33, the steel plate will be moved by the slide rail 32. During the movement, the second hydraulic device 35 on both sides will drive the fourth telescopic rod 36 to extend, thereby driving the push plate 37 to push the steel plate under the third support plate 310 on both sides. The third hydraulic device 38 will drive the fifth telescopic rod 39 to drive the pressing plate 311 and the cutting plate 312 to process the steel plate.

[0057] The cutting box 31 is located on the top of the base plate 1, and the side of the cutting box 31 away from the insertion plate 33 is connected to the spray unit 4.

[0058] like Figure 12 The spray unit 4 shown includes a spray channel 41, an outlet 42 at the bottom of the spray channel 41, a fourth support plate 43 on the outer surface of the spray channel 41, a second motor 44 on the outer surface of the fourth support plate 43, a second reciprocating screw 45 at the output end of the second motor 44, a second moving block 46 threadedly connected to the outer surface of the second reciprocating screw 45, a clamping mechanism 48 on the outer surface of the second moving block 46, and spray nozzles 47 evenly arranged at the top of the spray channel 41. The front spray nozzles 47 spray clean water, and the rear spray nozzles 47 spray lubricating fluid.

[0059] After cutting, the steel plate will enter the clamping mechanism 48 along the slide 32. The second motor 44 will drive the second reciprocating screw 45 to rotate and control the second moving block 46, the clamping mechanism 48 and the steel plate to move in the spray channel 41. During this process, the nozzle 47 will spray clean water and lubricant respectively, which not only washes the steel plate but also sprays the lubricant to the target area in the form of mist or column, thereby reducing the adhesion of zinc layer.

[0060] like Figure 13 As shown, the clamping mechanism 48 includes a support bar 481. A third motor 482 is provided on the outer surface of the support bar 481. A third rotating shaft 483 is fixedly connected to the output end of the third motor 482. A frame plate 484 is provided at the end of the third rotating shaft 483 away from the third motor 482. Electric cylinder plates 485 are symmetrically arranged on both sides of the frame plate 484. A telescopic clamping plate 486 is provided on the electric cylinder plate 485.

[0061] When the steel plate enters the frame plate 484, it enters from the side of the frame plate 484 closest to the slide 32. During the spraying process, the third motor 482 drives the third rotating shaft 483 to rotate, so that each side of the steel plate is fully sprayed. After the frame plate 484 moves close to the outlet 42, the electric cylinder plate 485 will cause the telescopic clamping plate 486 to retract, so that the steel plate falls onto the placement plate 53.

[0062] One end of the spray channel 41 is fixedly connected to the outer surface of the cutting box 31, and the outer surface of the support bar is fixedly connected to the outer surface of the second moving block.

[0063] The working process of the automatic processing equipment for U-shaped clamps of spiral ducts provided by this invention is as follows:

[0064] First, after the steel plate is placed into the placement plate 33, it will be moved by the slide rail 32. During the movement, the second hydraulic devices 35 on both sides will drive the fourth telescopic rod 36 to extend, thereby driving the push plate 37 to push the steel plate under the third support plates 310 on both sides. The third hydraulic device 38 will drive the fifth telescopic rod 39 to drive the pressing plate 311 and the cutting plate 312 to process the steel plate. Afterwards, the steel plate will enter the clamping mechanism 48 along the slide rail 32. The second motor 44 will drive the second reciprocating screw 45 to rotate and control the rotation. The second moving block 46, the clamping mechanism 48, and the steel plate move in the spray channel 41. During this process, the nozzle 47 sprays clean water and lubricating fluid respectively. During the spraying process, the third motor drives the third rotating shaft to rotate, so that each side of the steel plate is fully sprayed. After the frame plate moves close to the outlet 42, the electric cylinder plate will retract the telescopic clamping plate, so that the steel plate falls onto the placement plate 53. After the treated steel plate falls onto the placement plate 53, the first hydraulic device 56 will drive the first telescopic rod 57 to extend, thereby pushing the placement plate 53. After rotating to a vertical position, the first motor 552 drives the first reciprocating screw 554 to rotate, thereby moving the first moving block 553 and moving the mold plate 557 and mold assembly 555 into the placement plate 53, and causing the mold unit to enter the notch 54 of the placement plate 53. As the placement plate 53 and mold assembly 555 press against each other, the steel plate initially adheres to the mold block 5552. Then, the first micro motor 5555 drives the large gear 5556 to rotate at a certain angle, accompanied by the rotation of the meshing small gear 5559. The rotation causes the first rotating shaft 5557 and the angle plate 5558 to rotate, thereby causing excessive bending of the mounting ears of the spiral duct U-shaped clamp. The second micro motor 5568 also drives the tilting plate to rotate to an angle that matches the angle plate 5558. The third telescopic rod 5561 extends and drives the side plate 5563 and the placement box 5564 to approach the mold assembly 555. Then, the energized neodymium magnet assembly 55510 generates a strong magnetic force, thereby attracting the neodymium magnet plate 5567 and driving the pressing arc plate 5566 and the tilting plate 5569 to press the steel plate.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
