Description

Technical Field

[0001] The utility model relates to plate processing, in particular to a bending device for aluminum-copper composite bars. Background Art

[0002] Copper-aluminum composite busbars, also known as copper-clad aluminum busbars, copper-clad aluminum busbars, or copper-clad aluminum busbars, are high-tech, energy-saving conductor materials that combine the electrical conductivity of copper with the low density of aluminum. They offer excellent conductivity, light weight, superior mechanical properties, a strong copper-aluminum bond, good ductility, and reliability, making them widely used in automation, metallurgy, high- and low-voltage electrical equipment, construction, and other industries. Currently, aluminum-copper composite busbars are mostly plate-shaped. Before bending, one end of the plate is placed in the bending device, while the other end is manually gripped or mechanically clamped. Next, the plate is bent using different dies on the bending device, depending on the desired shape. Finally, a cutting mechanism is used to cut the plate, completing the processing of the plate components.

[0003] However, existing bending devices require multiple manual transfers of the processed sheet material, and the sheet material needs to be manually held and mechanically clamped multiple times, which makes the operation steps relatively cumbersome. For these reasons, it is necessary to design a bending device that can continuously bend the sheet material without multiple sheet removal and positioning. Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the present invention is to provide a bending device for an aluminum-copper composite bar, which realizes the rapid removal and positioning of the plate and the continuous bending processing of the bending device.

[0005] To achieve the above purpose, the technical solution of this utility model is as follows:

[0006] A bending device for an aluminum-copper composite bar comprises an upper die and a lower die arranged inside the bending device, a cutting mechanism and a clamping mechanism arranged at the feed end of the bending device, a material guide platform being arranged between the lower die and the feed end and the discharge end, a push-up assembly being arranged through the lower die for the processing of the plate in and out, two groups of clamping mechanisms being provided, and the clamping mechanisms being parallel to the lower die in sequence, a receiving plate being provided on both groups of clamping mechanisms, and a linear guide being provided at the lower end of the clamping mechanism away from the lower die for the continuous bending processing of the plate.

[0007] Preferably, the pushing assembly includes a lower tube arranged in the lower mold, an upper rod slidingly provided in the lower tube and passing through the lower mold, a same spring is sleeved between the upper rod and the lower tube, and a ball is rotatably provided on the top of the upper rod.

[0008] Preferably, the upper rod and the lower mold have the same height, and the length of the spring is greater than the height of the upper rod.

[0009] Preferably, a damping block is provided in the middle of the spring, and the outer side of the damping block is in contact with the lower tube.

[0010] Preferably, a transition plate is provided on the upper side of the lower die on the pushing assembly, and transition ends are provided at both ends of the transition plate close to the inlet and outlet.

[0011] Preferably, a clamping portion is provided in the middle of the receiving plate, which is inclined inwardly relative to the two clamping portions, and clamping strips are provided on the inner sides of the two receiving plates.

[0012] Preferably, the linear guide rail is vertically distributed to the lower mold, a load platform connected to one of the clamping mechanisms is slidably provided on the linear guide rail, and the other clamping mechanism is connected to the linear guide rail via a support rod.

[0013] Compared with the prior art, the bending device for aluminum-copper composite bars provided by the present invention can quickly move the processed bent sheet out of the lower die, and quickly move the sheet to be processed to the lower die, thereby realizing continuous processing of the bending device. Specifically, the setting of the upper push-up assembly on the lower die facilitates the use of the upper end ball and transition plate of the push-up assembly to slide the unprocessed sheet to the upper side of the lower die, and then press the sheet downwards and bend it through the upper die, the cutting mechanism cuts off the sheet, and the upper die is reset and retracted. The spring in the push-up assembly can drive the upper rod to push the sheet, separating the sheet from the lower die; then, the sheet is driven to be pushed toward the lower die again through the linear guide rail, and the bent sheet will slide from the upper side of the lower die to the material guide table through the ball and transition end, and then be moved out of the bending device, and the bending device performs bending processing again, thereby realizing continuous processing of the bending device.

[0014] And through the setting of two clamping mechanisms on the bending device, the linear guide rail is driven by one clamping mechanism, so that the clamping mechanism can push the plate into the bending device, and can also cooperate with another clamping mechanism to limit and clamp one end of the plate, and clamp the new plate into the clamping mechanism to realize the continuous material processing of the plate, reduce the multiple removal and limitation of the plate, simplify the bending operation of the plate, and is very beneficial for the sustainable processing of the bending device.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] As attached Figure 1 and attached Figure 2As shown, the bending device provided by the embodiment of the present invention is used for the bending processing of aluminum-copper composite bars. The shape of the bent plate can be determined by the upper die 11 and the lower die 12 arranged inside the bending device. The plate can be clamped during processing and the plate can be cut after processing by using the cutting mechanism 13 and the clamping mechanism 2 arranged at the feed end of the bending device. It is worth noting that the cutting mechanism 13 and the clamping mechanism 2 in this embodiment are both existing structures of the bending device. The clamping mechanism 2 in the existing bending device uses relatively distributed clamps. The two clamps are driven to move to the middle position by the cylinder, and the plate placed in the middle of the clamping mechanism 2 can be clamped, thereby achieving the limited fixation of the plate. At present, the cutting mechanism 13 of the bending device uses a hydraulic cylinder as a driving structure. The power drive of the hydraulic cylinder can drive the cutting knife to move and cut and separate the plate at the feed end. In this embodiment, the processed bent sheet can be guided out through the same material guide platform 4 set between the lower die 12 and the feed end and the discharge end; the processed sheet can be brought in and removed through the ejecting assembly 5 set through the lower die 12, and the number of clamping mechanisms 2 is set to two groups. The clamping mechanisms 2 and the lower die 12 are set in parallel in sequence, which facilitates the sequential introduction of the sheets. The receiving plates 3 are set on both groups of clamping mechanisms 2, and the linear guide rail 7 is set at the lower end of the clamping mechanism 2 away from the lower die 12, which facilitates the two clamping mechanisms 2 to clamp the processed sheets while adding new sheets to perform continuous bending processing of the sheets.

[0026] Among them, it is worth mentioning that Figure 2 and 3 As shown, when the bending device uses the upper die 11 to press the lower die 12 to perform the bending work, the push assembly 5 can be pressed into or ejected from the lower die 12 through the bending work of the upper die 11, bend the plate and then separate it from the lower die 12, which provides convenience for moving the processed plate in and out. By setting two clamping mechanisms 2, it is convenient for the bending device to bend the plate while using the receiving plate 3 to add a new plate to the plate that is about to be processed. Through the push of the linear guide 7, the two plate clamping mechanisms 2 are slightly opened, and the tail end of the new plate can be stuck in the clamping mechanism 2. With the push of the linear guide 7, the new plate can be driven to continue the unprocessed plate without multiple plate limiting. The bent plate can also be quickly moved out, realizing the continuous processing of the bending device, improving the processing rate of the bending device, and reducing the frequency of material change.

[0027] In order to facilitate the placement of the plate to be processed above the lower die 12 and to push the processed bent plate out of the lower die 12, a push assembly 5 is provided on the lower die 12 in this embodiment. Figure 4As shown, the push-up assembly 5 includes a lower tube 52 disposed in the lower die 12, an upper rod 51 that penetrates the lower die 12 is slidably disposed in the lower tube 52, a spring 53 is sleeved between the upper rod 51 and the lower tube 52, and a ball 55 is rotatably disposed on the top of the upper rod 51. When the push-up assembly 5 is in use, the pushed-in sheet will push the ball 55 downward to press the upper rod 51, and the rolling of the ball 55 on the upper rod 51 can drive the sheet to slide quickly onto the lower die 12, completing the sheet position. During the bending process, the bent sheet is pressed into the die groove of the lower die 12, squeezing the spring 53, pressing the upper rod 51 into the lower tube 52, and increasing the bending shape of the sheet. When the upper die 11 of the bending device squeezes the lower die 12 to complete the bending of the sheet, the cutting mechanism 13 separates the bent sheet from the sheet, lifts the upper die 11 and separates the lower die 12, and the spring 53 in the pushing assembly 5 drives the upper rod 51 to reset, and the ball 55 pushes the sheet to separate from the die groove, and then pushes the clamping mechanism 2 into the bending device again through the linear guide rail 7. The sheet pushes the bent sheet, and the bent sheet slides away from the lower die 12 through the ball 55 and falls onto the guide table 4 for collection, completing the access and removal of the sheet, saving labor to move the sheet out and in, and no mechanical re-clamping process is required, so that the continuous processing of the bending device can be achieved, thereby improving the processing speed of the bending device.

[0028] For better sheet material removal and removal, reducing processing steps, such as Figure 3 and 4 As shown, the upper rod 51 is at the same height as the lower die 12, and the length of the spring 53 is greater than the height of the upper rod 51. The upper rod 51 and the lower die 12 are arranged at the same height, so when the plate slides into the lower die 12, it will directly contact the ball 55. The rotation of the ball 55 on the upper rod 51 makes it more convenient to move the plate in and out.

[0029] A further step is to facilitate the stable separation of the plate from the middle of the lower die 12, such as Figure 4 As shown, a damping block 54 can be provided in the middle of the spring 53, with the outer side of the damping block 54 in contact with the lower tube 52. The contact between the outer side of the damping block 54 and the inner wall of the lower tube 52 facilitates the smooth ejection of the sheet metal from the die groove when the spring 53 is compressed or reset, thereby increasing the telescopic stability of the ejection assembly 5, preventing the sheet metal from angularly swinging due to the reset of the spring 53, preventing the sheet metal from angularly deviating, and increasing the accuracy of sheet metal removal.

[0030] In order to better remove the processed sheet from the die cavity, Figure 3As shown, the push assembly 5 can be further provided with a transition plate 6 on the upper side of the lower die 12. Both ends of the transition plate 6, near the material inlet and outlet, are provided with transition ends 61. The provision of the transition ends 61 at both ends of the transition plate 6 facilitates the sliding of the sheet material onto the transition plate 6 and facilitates the sliding of the bent sheet material off the transition plate 6, facilitating the entry of unprocessed sheet material and the removal of processed sheet material, thereby increasing the versatility of the push assembly 5.

[0031] In order to better replace the sheet material and ensure the continuous processing of the bending device, in some embodiments, it is also possible to Figure 5 As shown, a clamping portion 31 is provided in the middle of the receiving plate 3, which is inclined inwardly relative to the two clamping portions 31. Clamping strips 32 are provided on the inner sides of the two receiving plates 3. The receiving plate 3 can clamp the ends of a wider plate, improving the plate's positional stability. The use of the clamping strips 32 on the inner side of the receiving plate 3 increases the contact pressure between the receiving plate 3 and the plate, improving the plate's clamping firmness, facilitating the insertion of plates on the two clamping mechanisms 2, and providing convenience for the subsequent insertion of new plates.

[0032] In order to better bend the plate and ensure the continuous conveying of the plate, such as Figure 1 and 5 As shown, the linear guide 7 is perpendicular to the lower die 12. A load platform 71, connected to one of the clamping mechanisms 2, is slidably mounted on the linear guide 7. The other clamping mechanism 2 is connected to the linear guide 7 via a support rod 72. It is worth noting that the sheet metal retaining end in the middle of the two clamping mechanisms 2 is at the same height as the lower die 12. When the sheet metal is positioned using the two clamping mechanisms 2, the linear guide 7 facilitates smooth movement of the sheet metal into the bending device, where the upper and lower dies 11, 12 perform the bending operation. This prevents sheet metal from shifting and facilitates continuous sheet metal conveyance.

[0033] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
