Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending tooling technology, specifically a continuous bending tooling for cable chain sheet metal. Background Technology
[0002] In photovoltaic equipment, cable chains are crucial components ensuring the safe operation of cables, and their design and application directly impact the stability and lifespan of the equipment. Cable chains are typically made from high-strength sheet metal through cold processing techniques (such as bending, welding, and stamping), featuring lightweight, high strength, and corrosion resistance, making them adaptable to the complex and varied outdoor environments of photovoltaic power plants. Cable chains require customized design based on the number of cables, bending radius, and installation space. For example, in cable management for photovoltaic inverters or combiner boxes, cable chains often employ a U-shaped channel structure with sufficient redundancy space at the bottom to prevent excessive cable stretching, while using flat-head screws for fixation to prevent interference. For photovoltaic power plants in coastal or high-humidity areas, hot-dip galvanized steel or aluminum alloy profiles are preferred for cable chains, combined with electrostatic powder coating to effectively resist salt spray corrosion and UV aging. During bending, cable chains typically require bending fixtures to bend multiple parallel bending lines on the sheet metal.
[0003] However, existing bending fixtures typically require manual handling of the sheet metal, placing it under the bending blade according to the bending line, and then bending it using the fixture, resulting in low bending efficiency. Utility Model Content
[0004] The purpose of this invention is to solve the problem of low bending efficiency in existing bending fixtures.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A cable chain sheet metal continuous bending fixture includes a first frame and a second frame. A first conveyor line and a second conveyor line are respectively arranged parallel to each other on the top of the first and second frames. Guide rails are detachably connected to the top of the opposing sidewalls of the first and second frames. A third frame is arranged on the side of the second frame away from the first frame. A pair of first lifting mechanisms are arranged on the top sidewall of the third frame. A pressure plate is detachably connected to the lifting platform of each first lifting mechanism. Several sets of bending mechanisms are symmetrically arranged between the first and second conveyor lines. Each bending mechanism includes a rotating plate. An arc-shaped plate is fixedly connected to one end of the rotating plate facing the guide rail. The arc-shaped plate is rotatably connected to the top of the side of the first or second frame facing the guide rail. An electric cylinder is hinged to the bottom of the rotating plate and rotatably connected to the bottom of the first or second frame.
[0007] Furthermore, a pair of bending grooves are symmetrically provided on both sides of the guide rail, and a pair of limiting plates are symmetrically fixedly connected to both sides of the bottom of the pressure plate, with the pair of limiting plates located directly above the pair of bending grooves.
[0008] Furthermore, the pressure plate is located directly above the guide rail, and the pressure plate is arranged parallel to the guide rail.
[0009] Furthermore, two sets of translation mechanisms are symmetrically arranged between the first conveyor line and the second conveyor line.

[0022] 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.
[0023] Please see Figure 1-6The cable chain sheet metal continuous bending fixture of this embodiment includes a first frame 1 and a second frame 2. A first conveyor line 4 and a second conveyor line 5 are respectively arranged parallel to each other on the top of the first frame 1 and the second frame 2. Several parallel conveyor rollers are arranged on the top of the first conveyor line 4 and the second conveyor line 5. Guide rails 13 are detachably connected to the top of the opposing sidewalls of the first frame 1 and the second frame 2. A third frame 3 is arranged on the side of the second frame 2 away from the first frame 1. A pair of first lifting mechanisms 9 are arranged on the top sidewall of the third frame 3. A pressure plate 10 is detachably connected to the lifting platform of the first lifting mechanism 9. Several sets of bending mechanisms 6 are symmetrically arranged between the first conveyor line 4 and the second conveyor line 5. The bending mechanism 6 is used to bend sheet metal. It includes a rotating plate 601, an arc-shaped plate 602 fixedly connected to one end of the rotating plate 601 facing the guide rail 13, the arc-shaped plate 602 being rotatably connected to the top of the first frame 1 or the second frame 2 facing the guide rail 13, and an electric cylinder 603 hinged to the bottom of the rotating plate 601. The electric cylinder 603 is rotatably connected to the bottom of the first frame 1 or the second frame 2. A pair of bending grooves 14 are symmetrically opened on both sides of the guide rail 13. A pair of limiting plates 12 are symmetrically fixedly connected to both sides of the bottom of the pressure plate 10. The pair of limiting plates 12 are respectively located directly above the pair of bending grooves 14. The pressure plate 10 is located directly above the guide rail 13 and is parallel to the guide rail 13. When bending the sheet metal, the I-shaped sheet metal is placed horizontally on top of the guide rail 13, with both sides of the sheet metal positioned at the top of the first conveyor line 4 and the second conveyor line 5, respectively. The sheet metal is conveyed via the first conveyor line 4 and the second conveyor line 5. During conveying, the initial position of the movable plate 601 and the top of the guide rail 13 are flush with the tops of the first conveyor line 4 and the second conveyor line 5. When the sheet metal reaches the bottom of the pressure plate 10, the first conveyor line 4 and the second conveyor line 5 stop moving, causing the sheet metal to stop moving. Then, the sheet metal is positioned so that the bending lines on both sides of the sheet metal surface are positioned at the top of the bending grooves 14 on both sides of the guide rail 13. At this time, the pressure plate 10 and the first lifting mechanism 9 drive the first lifting mechanism 9 to lift the sheet metal. The limiting plate 12 moves downward until it abuts against the bending line of the sheet material, pressing and limiting the bending position of the sheet material. Then, the electric cylinder 603 at the bottom of the first frame 1 and the second frame 2 drives the movable plate 601 at its top to rotate upward around the connection between the arc plate 602 and the first frame 1 and the second frame 2, thereby driving the parts to be bent on both sides of the sheet material to rotate upward along the bending line, thus realizing the rapid bending of the sheet material. After the sheet material is bent to the set angle, the limiting plate 12 and the bending mechanism 6 are reset. At this time, the first conveyor line 4 and the second conveyor line 5 drive the bent sheet material to move backward. Repeating the above steps can realize continuous and rapid bending of the sheet material, effectively improving bending efficiency.
[0024] Two sets of translation mechanisms 7 are symmetrically arranged between the first conveyor line 4 and the second conveyor line 5. The moving table of the translation mechanism 7 is fixedly connected to the limiting cylinder 8, and the piston rod of the limiting cylinder 8 is fixedly connected to the push block 11. The translation mechanism 7 is located between the bending mechanisms 6. When positioning the sheet metal, the translation mechanisms 7 on both sides drive the limiting cylinder 8 to move towards each other until the push block 11 abuts against the edge of the sheet metal. At this time, the limiting cylinder 8 on both sides of the sheet metal drives the push block 11 to push out synchronously, so that the position of the sheet metal is corrected, and the bending lines on both sides of the sheet metal surface are respectively located at the top of the bending grooves 14 on both sides of the guide rail 13, thereby achieving the positioning of the sheet metal and improving the bending accuracy.
[0025] A pair of photoelectric sensors 16 are installed on the top of the first frame 1 and the second frame 2 facing the feeding port. A baffle 15 is installed on the side of the photoelectric sensor 16 away from the bending mechanism 6. A second lifting mechanism 17 is vertically fixed to the bottom of the baffle 15. When the end of the sheet passes the photoelectric sensor 16, the first conveyor line 4 and the second conveyor line 5 stop moving. At the same time, the second lifting mechanism 17 drives the baffle 15 to move upward to block the sheet and prevent the sheet from moving past the bending station due to inertia.
[0026] Working principle: When bending the sheet metal, the I-shaped sheet metal is placed horizontally on the top of the guide rail 13, with the two sides of the sheet metal positioned at the top of the first conveyor line 4 and the second conveyor line 5, respectively. The sheet metal is conveyed by the first conveyor line 4 and the second conveyor line 5. During conveying, the initial position of the movable plate 601 and the top of the guide rail 13 are flush with the tops of the first conveyor line 4 and the second conveyor line 5. When the sheet metal moves to the bottom of the pressure plate 10, the end of the sheet metal passes the top of the photoelectric sensor 16, and the first conveyor line 4 and the second conveyor line 5 stop moving. At the same time, the second lifting mechanism 17 drives the baffle 15 to move upward to block the sheet metal and prevent it from moving past the bending station due to inertia. Then, the sheet metal is positioned. During positioning, the translation mechanism 7 on both sides drives the limiting cylinder 8 to move towards each other until the push block 11 abuts against the edge of the sheet metal. At this time, the limiting cylinder 8 on both sides of the sheet metal drives the push block 11 to push it out synchronously. This process aligns the plate with the bending lines on both sides of the plate surface, positioning them at the top of the bending grooves 14 on both sides of the guide rail 13, thus improving bending accuracy. At this point, the first lifting mechanism 9 drives the pressure plate 10 and the limiting plate 12 downwards until the limiting plate 12 abuts against the bending lines of the plate, pressing and limiting the bending position. Then, the electric cylinder 603 at the bottom of the first frame 1 and the second frame 2 drives the movable plate 601 at its top to rotate upwards around the connection between the arc plate 602 and the first frame 1 and the second frame 2, thereby causing the parts to be bent on both sides of the plate to rotate upwards along the bending lines, achieving rapid bending of the plate. After the plate is bent to the set angle, the limiting plate 12 and the bending mechanism 6 reset, at which point the first conveyor line 4 and the second conveyor line 5 drive the bent plate backwards. Repeating the above steps allows for continuous and rapid bending of the plate, effectively improving bending efficiency.
