[0045] Embodiment
[0046] Please refer to Figures 1 to 5 The embodiment of the present application shown provides an integrated processing device for a busbar trough terminal cover. In practical applications, continuous galvanized steel strips are input into the integrated processing device for the busbar trough terminal cover manually or through a feeding device, and several sections of terminal cover plates that are convenient for storage are processed and formed. The processed terminal cover plates include a terminal cover top plate with folded edges, and terminal cover side plates connected to both sides of the terminal cover top plate. When in use, the two terminal cover side plates can be manually bent along the bending process holes to obtain the terminal cover;
[0047] Please refer to Figure 1 And Figure 2 , the integrated processing device for the busbar trough terminal cover includes: an upper die base 1, a convex die group 11, a lower die base 2, and a concave die 21; among them, the upper die base 1 adopts a rectangular plate structure; a die shank for connecting the upper press is fixed on the upper surface of the upper die base 1; the die shank can disperse the impact and vibration during stamping, prevent the upper die base 1 from shaking during the processing, and thus ensure the forming quality and accuracy of the terminal cover.
[0048] The lower die base 2 is a cuboid plate structure, the width of which matches that of the upper die base 1. The lower die base 2 is located directly below the upper die base 1 and is used to bear the pressure transmitted from above to maintain the stamping stability of the device.
[0049] The female die 21 is in a strip structure and is connected to the upper surface of the lower die base 2. The length of the female die 21 matches that of the lower die base 2. A number of punching holes matching the shape and size of the male die set 11 are provided on the female die 21. During processing, the male die set 11 cooperates with the female die 21 to complete the stamping operation, and part of the male die set 11 is pressed into the corresponding punching holes to realize punching, notching, shearing and flanging processing on the steel strip.
[0050] The male die set 11 is connected below the upper die base 1. The male die set 11 is in an overall strip structure, and its two ends are respectively a feeding end and a discharging end. The steel strip is laid on the surface of the female die 21 and is conveyed from the feeding end to the discharging end. The male die set 11 is successively provided with adjacent first and second stations along the conveying direction of the steel strip. Among them, the first station is close to the end of the male die set 11 where the steel strip is input. A first male die 111 is provided at the first station. During the processing, the first male die 111 cooperates with the female die 21 to process the steel strip in the first station into a terminal cover side plate on one side. The second station includes a second male die 112 and a pressing plate 113. During the processing, the second male die 112 cooperates with the female die 21 to process the steel strip in the second station into a terminal cover side plate on the other side and shear it into individual terminal cover plates. The pressing plate 113 cooperates with the female die 21 to form flanges on both sides of the steel strip in the second station. With the design of the male die set 11, after the steel strip enters the equipment, the section to be processed can be successively stamped at two stations respectively and formed into terminal cover plates. This design optimizes the number of steps required to form terminal cover plates in the related technology, improves the processing standardization degree, and all steps are realized on the same equipment, reducing the number of equipment required for processing, and thus reducing the complexity of the production line.
[0051] Please refer to Figure 3 and Figure 4, in this embodiment, the first punch 111 includes: a plurality of first strip-shaped dies 1111, two first column dies 1112, and a plurality of second strip-shaped dies 1113 (not shown in the figure); as an implementation manner of the present application, the first strip-shaped die 1111 has a long strip structure, which is perpendicular to the lower surface of the upper die base 1, and a plurality of first strip-shaped dies 1111 are arranged in a straight line perpendicular to the conveying direction of the steel strip to form a first strip-shaped die group. The distance from the first strip-shaped die group to the second station matches the length of the terminal cover side plate; during the processing, the first strip-shaped die 1111 is pressed into the punching holes at the corresponding positions of the female die 21, and a plurality of bending process holes arranged in a straight line are punched on the surface of the steel strip; at the same time, the steel strip in the area between the bending process holes and the second station is stamped to form a terminal cover side plate; the punched bending process holes are used to reduce the bending force required when folding the terminal cover, achieve the effect of releasing the bending stress, and reduce the springback after bending; in the above technical solution, a uniformly wide gap is provided between adjacent first strip-shaped dies 1111, and the steel strip not affected by stamping in the gap plays a connecting role between the terminal cover side plate and the steel strip.
[0052] In order to process a V-shaped notch on the edge of the steel strip so that the terminal cover plate after flanging is easy to be folded into a busbar terminal cover; the first column die 1112 has a triangular prism structure, and the two first column dies 1112 are perpendicular to the lower surface of the upper die base 1 and are respectively located at both ends of the first strip-shaped die group; in the above technical solution, the apex angles of the two first column dies 1112 are arranged opposite to each other, and the distance between the two first column dies 1112 matches the width of the steel strip, so that the stamping positions of the first column dies 1112 on the steel strip are on both sides of the steel strip; during processing, the two first column dies 1112 are driven by the upper die base 1 to contact the steel strip and further press into the corresponding punching holes on the female die 21, and V-shaped notches are punched on both sides of the steel strip; during the later process of folding the terminal cover plate into a terminal cover, the V-shaped notches gradually close, and the baffle formed by the contact of the flanges is used to protect the busbar inside the terminal cover.
[0053] A plurality of second strip-shaped dies 1113 are arranged in the area between the second station and the first strip-shaped die group and are perpendicular to the lower surface of the upper die base 1. The second strip-shaped die 1113 is used to cooperate with the female die 21 to punch mounting holes on the steel strip.
[0054] With the design of the first punch 111, after the steel strip is input into the equipment, one side of the terminal cover plate side plate can be stamped and formed in the first station, and the bending process holes between the terminal cover top plate and one side plate can be processed and the notching work on both sides of the bending process holes can be completed by a single stamping action. This design optimizes the processing steps of the terminal cover plate and improves the production efficiency.
[0055] In this embodiment, the second punch 112 includes: a plate-shaped die 1121, several third strip-shaped dies 1122, two second column-shaped dies 1123, and several fourth strip-shaped dies 1124;
[0056] Among them, the plate-shaped die 1121 is perpendicular to the lower surface of the upper die base 1 and is parallel to the first strip-shaped die group. The distance from the first strip-shaped die group to the plate-shaped die 1121 matches the length of the side plate of the terminal cover. During processing, after the steel strip moves to the corresponding position, the plate-shaped die 1121 presses into the female die 21 to shear the steel strip. After being sheared by the plate-shaped die 1121, the area corresponding to the first station is the steel strip; the area corresponding to the second station is the terminal cover plate formed by shearing. The design of the plate-shaped die 1121 optimizes the step of transferring the steel plate to the shearing equipment for shearing in the traditional solution.
[0057] The third strip-shaped die 1122 is perpendicular to the lower surface of the upper die base 1. The shape and quantity of the third strip-shaped die 1122 match those of the first strip-shaped die 1111. Several third strip-shaped dies 1122 are linearly arranged along the direction parallel to the first strip-shaped die group to form a third strip-shaped die group. The shape of the second column-shaped die 1123 matches that of the first column-shaped die 1112. Two second column-shaped dies 1123 are symmetrically arranged on both sides of the third strip-shaped die group. The shape and quantity of the fourth strip-shaped die 1124 match those of the second strip-shaped die 1113. Several fourth strip-shaped dies 1124 are arranged in the area between the plate-shaped die 1121 and the third strip-shaped die group. As an implementation manner of this application, the first strip-shaped die group and the third strip-shaped die group, the first column-shaped die 1112 and the second column-shaped die 1123, and the second strip-shaped die 1113 and the fourth strip-shaped die 1124 are all symmetrically distributed with respect to the plane where the plate-shaped die 1121 is located. The symmetric design ensures that the lengths of the two-sided terminal cover side plates obtained by each processing match, and the positions of the bending process holes, V-shaped notches, and port mounting holes on the two-sided terminal cover side plates correspond. When the upper die base 1 drives the second punch 112 to shear the steel strip in the technical solution of this application, it also drives the first punch 111 to punch the steel strip, that is, the punch group 11 can simultaneously perform symmetric stamping actions on the steel strips on both sides of the plate-shaped die 1121 to ensure the symmetry of the finished two-sided side plates of the terminal cover.
[0058] In the above technical solution, a backing plate 12 is further provided between the punch group 11 and the upper die base 1. The backing plate 12 is used to bear the punching force generated during the stamping of the punch group 11 to prevent the upper die base 1 from being sunken or deformed.
[0059] While the stamping operation is performed on the convex die set 11, the pressing plate 113 performs hemming on the steel strip in the second station; in this embodiment, the pressing plate 113 is in the structure of a rectangular parallelepiped plate, and its length is at least greater than the length of the second station. The pressing plate 113 is located between the upper die holder 1 and the female die 21. A hemming convex groove 1131 is provided on the area of the lower surface of the pressing plate 113 corresponding to the second station, which is used to cooperate with the female die 21 to perform hemming on the steel strip; in the above technical solution, a through hole adapted to the shape, size and position of the second punch 112 is provided on the pressing plate 113, and the second punch 112 is inserted through the through hole; the pressing plate 113 plays a role in fixing the second punch 112, restricting its lateral deformation during stamping, and avoiding dimensional deviation or even distortion of the finished product; as a preferred embodiment of the present application, the length of the pressing plate 113 matches that of the female die 21, and through holes adapted to the shapes, sizes and positions of the first punch 111 and the second punch 112 are provided on the pressing plate 113. Both the first punch 111 and the second punch 112 are inserted through the through holes. With this technical solution, the pressing plate 113 can simultaneously form a restraint on the first punch 111 and the second punch 112; it can be understood that the lower surfaces of the first punch 111 and the second punch 112 both protrude from the lower surface of the pressing plate 113; during processing, the parts of the first punch 111 and the second punch 112 protruding from the lower surface of the pressing plate 113 are pressed into the female die 21 to perform punching and shearing on the steel strip.
[0060] More specifically, the hemming convex groove 1131 is arranged along the conveying direction of the steel strip, and its width matches the width of the terminal cover of the busbar. One end of the hemming convex groove 1131 is connected to one side of the plate-shaped die 1121, and the lower surface of the plate-shaped die 1121 is lower than the lower surface of the hemming convex groove 1131; with this technical solution, when the upper die holder 1 drives the convex die set 11 to approach the steel strip, the plate-shaped die 1121 first contacts the steel strip, and then the hemming convex groove 1131 contacts the steel strip, so as to achieve the technical effect of shearing first and then hemming. In this embodiment, a groove 211 adapted to the hemming convex groove 1131 is provided on the female die 21; the groove 211 corresponds to the position of the hemming convex groove 1131 and has a matching length; during processing, the hemming convex groove 1131 presses the steel strip into the groove 211 to form hems on both sides of the steel strip; please refer to Figure 5 , it can be understood that several punching holes cooperating with the second punch 112 are arranged at the bottom of the groove 211 in the area corresponding to the second station; the width of the groove 211 is greater than the width of the hemming convex groove 1131, so that after the hemming convex groove 1131 is pressed into the groove 211, the gap between the two can accommodate the steel strip, avoiding the hems of the steel strip from being completely cut off during stamping.
[0061] As a preferred embodiment of the present application, the depth of the groove 211 is less than the hemming width of the steel strip; after the hemming process is completed, the hem of the steel strip protrudes from the upper surface of the female die 21; with this design, when the rear steel strip continues to be conveyed forward, it can push out the steel strip that has been hemmed and processed in the front from the equipment.
[0062] As a preferred embodiment of the present application, a number of buffer pads 121 are provided between the pressure plate 113 and the backing plate 12. The pressure plate 113 is connected below the backing plate 12 through the buffer pads 121. The buffer pads 121 are used to compensate for the dimensional difference and vibration between the backing plate 12 and the pressure plate 113, keep the convex die set 11 stable, reduce the damage caused by impact to the convex die set 11, and can effectively extend the service life of the convex die set 11.
[0063] As a preferred embodiment of the present application, at least two guide posts 22 are provided on the lower die base 2; the guide posts 22 are perpendicular to the upper surface of the lower die base 2; a guide sleeve 13 adapted to the guide posts 22 is provided at the corresponding position on the lower surface of the upper die base 1. The guide posts 22 are connected in the guide sleeve 13, so that the upper die base 1 can move relative to the lower die base 2 along the direction of the guide posts 22; the design of the cooperation between the guide posts 22 and the guide sleeves 13 is used to accurately guide and position the convex die set 11. The upper die base 1 is guided by the guide posts 22 to move along a predetermined path during the stamping process, and the consistency of each stamping profile is maintained.
[0064] When the steel strip to be processed enters the integrated processing equipment for the busbar terminal cover provided by the present application for processing, first, one side of the terminal cover side plate is processed and formed in the first station, and then it is conveyed to the second station to process and form the other side of the terminal cover side plate, and it is cut into terminal cover plates that are convenient for storage; the integrated processing equipment for the busbar terminal cover provided by the present application enables each section of the steel strip to form the terminal cover plate only after two stamping operations on the same processing equipment, solving the technical problems in the related art that the steel strip needs to be transferred and repositioned between multiple processing equipment, resulting in a large number of operating steps and low standardization in the processing process, effectively improving the production efficiency and reducing the complexity of the busbar terminal cover production line.
[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
