Description

Technical Field

[0001] This utility model belongs to the field of electric meter box manufacturing technology, specifically relating to a plate bending device for electric meter box plates. Background Technology

[0002] Electricity meter boxes, as a key infrastructure component of power transmission and distribution systems, are widely used in residential communities, industrial and commercial sites, and public buildings. Their enclosures primarily house and protect electricity metering instruments, switches, and wiring. Currently, meter box enclosures are mostly made of metal sheets (such as galvanized steel or stainless steel) or high-strength engineering plastics. Among these, metal enclosures hold a significant market share due to their high mechanical strength, good protection rating, excellent fire resistance, and relatively moderate cost.

[0003] The plate bending process is a key step in transforming a pre-processed flat plate into a specific three-dimensional box structure through extrusion deformation. Its processing accuracy and efficiency directly determine the dimensional consistency, assembly convenience, and the quality and appearance of the final product.

[0004] However, existing bending devices bend multiple edges of the sheet material sequentially during processing, which is inefficient and prone to misalignment when changing sides. Utility Model Content

[0005] The purpose of this utility model is to provide a plate bending device for electric meter boxes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a meter box plate bending device, including a workbench, and an integrated bending plate assembly is provided above the workbench;

[0007] The integrated folding plate assembly includes a support frame fixedly connected to the top surface of the workbench. A first hydraulic cylinder is mounted on the bottom surface of the support frame. The piston rod of the first hydraulic cylinder is fixedly connected to a positioning frame. Two guide rods are symmetrically fixedly connected to the top surface of the positioning frame. The two guide rods pass through the surface of the support frame and are slidably connected to the support frame. A second hydraulic cylinder is mounted inside the workbench via a bracket. The piston rod of the second hydraulic cylinder is fixedly connected to a connecting frame. Several limiting grooves are formed on the top surface of the workbench. The first hydraulic cylinder and the second hydraulic cylinder are on the same axis, and the plate is located on the top surface of the workbench and below the positioning frame.

[0008] As a further embodiment of this utility model, the positioning frame is a hollow, through-hole square frame structure, and the outer wall dimension of the positioning frame is the same as the bending position of the plate.

[0009] As a further embodiment of this utility model, four extrusion blocks are uniformly fixedly connected to the top surface of the connecting frame, and each extrusion block corresponds to each of the limiting grooves.

[0026] 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.

[0027] Please see Figures 1-6 This utility model provides a plate bending device for an electric meter box, including a workbench 1, and an integrated bending assembly is provided above the workbench 1;

[0028] The integrated folding plate assembly includes a support frame 2 fixedly connected to the top surface of the workbench 1. A first hydraulic cylinder 3 is installed on the bottom surface of the support frame 2. The piston rod of the first hydraulic cylinder 3 is fixedly connected to a positioning frame 4. Two guide rods 5 are symmetrically fixedly connected to the top surface of the positioning frame 4. The two guide rods 5 pass through the surface of the support frame 2 and are slidably connected to the support frame 2. A second hydraulic cylinder 7 is installed inside the workbench 1 through a bracket. The piston rod of the second hydraulic cylinder 7 is fixedly connected to a connecting frame 8. Several limiting grooves 6 are opened on the top surface of the workbench 1. The first hydraulic cylinder 3 and the second hydraulic cylinder 7 are on the same axis, and the plate is located on the top surface of the workbench 1 and below the positioning frame 4.

[0029] The positioning frame 4 is a hollow, through-hole square frame structure. The outer wall dimension of the positioning frame 4 is the same as the bending position of the plate. Four extrusion blocks 9 are evenly fixedly connected to the top surface of the connecting frame 8, and each extrusion block 9 corresponds to each limiting groove 6. The adjacent sides of the four extrusion blocks 9 are all located on the outer side of the outer wall of the positioning frame 4 and do not fit with the positioning frame 4. The top surface of the extrusion block 9 is an arc structure and is made of stainless steel.

[0030] When it is necessary to bend the sheet metal, place the sheet metal on the top surface of the workbench 1 and align the axis of the sheet metal with the axis of the first hydraulic cylinder 3. Then, start the first hydraulic cylinder 3. The piston rod of the first hydraulic cylinder 3 will push the positioning frame 4 to move towards the sheet metal. The guide rod 5 will slide inside the support frame 2. Through the limiting of the guide rod 5, the positioning frame 4 can move stably until the positioning frame 4 is in contact with the sheet metal and the sheet metal is stably limited. At this time, the outer wall of the positioning frame 4 should be coaxial with the bending line of the sheet metal, thus realizing the limiting of the sheet metal.

[0031] Then, the second hydraulic cylinder 7 is activated. The piston rod of the second hydraulic cylinder 7 pushes the connecting frame 8 to move upward. The extrusion block 9 is carried upward by the connecting frame 8 until the extrusion block 9 passes through the limiting groove 6 and is in contact with the bottom surface of the plate. The extrusion block 9 will continue to move upward. The plate will deform due to the pressure of the extrusion block 9. Due to the limitation of the positioning frame 4, it will bend at the bending line. Due to the arc-shaped design of the extrusion block 9 and the smoothness of its own material, the plate will slide on the top surface of the extrusion block 9 when bending, avoiding damage to the plate during bending.

[0032] In this utility model, a first slide rail 11 is provided above the workbench 1. Two positioning plates 10 are symmetrically slidably connected to the surface of the first slide rail 11. Two sets of pin holes are symmetrically opened on the bottom surface of the first slide rail 11, and each set of pin holes consists of six positioning holes arranged along the axis. A first pin 13 is slidably connected to the surface of each positioning plate 10, and the first pin 13 is inserted into the positioning hole.

[0033] The top surface of the workbench 1 is symmetrically and fixedly connected to two second slide rails 12. The first slide rail 11 is slidably connected to the second slide rail 12. Each second slide rail 12 has several positioning holes along its axis on its surface. The surface of the first slide rail 11 is slidably connected to the corresponding positions of the two second slide rails 12. The second pins 14 are inserted into the positioning holes. The positioning plate 10 has an L-shaped structure and the corners of the positioning plate 10 are rounded.

[0034] Before placing the board, the first slide rail 11 is adjusted according to the length of the board, so that the first slide rail 11 slides on the surface of the second slide rail 12 until it slides to an appropriate distance. Then, the second pin 14 is inserted into the corresponding positioning hole on the surface of the second slide rail 12, thereby adjusting the position of the first slide rail 11. The movement of the first slide rail 11 will drive the two positioning plates 10 to move accordingly. After the position of the first slide rail 11 is adjusted, the positions of the two positioning plates 10 are moved so that the two positioning plates 10 slide synchronously on the surface of the first slide rail 11, thereby changing the distance between the two positioning plates 10. After adjusting to the appropriate position, the position of the positioning plate 10 is limited by inserting the first pin 13 into the positioning hole on the bottom surface of the first slide rail 11. Since the two sets of pin holes are symmetrically arranged, the position of the other positioning plate 10 can be adjusted by the positioning pin hole of one positioning plate 10, thereby achieving symmetrical adjustment. Then, when placing the board, one side of the board is made to fit against the two positioning plates 10, thus limiting the position of the board.

[0035] It should be noted that in this application, the hydraulic cylinder is an actuator in the hydraulic system, which realizes the telescopic function by cooperating with the hydraulic system, and realizes the precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0036] The use of this utility model involves the following steps:

[0037] S1: When it is necessary to bend the sheet metal, place the sheet metal on the top surface of the workbench 1, aligning the axis of the sheet metal with the axis of the first hydraulic cylinder 3. Then, activate the first hydraulic cylinder 3. The piston rod of the first hydraulic cylinder 3 will push the positioning frame 4 towards the sheet metal. The guide rod 5 will slide inside the support frame 2. Through the limiting of the guide rod 5, the positioning frame 4 can move stably until the positioning frame 4 is in contact with the sheet metal, and the sheet metal is stably limited. At this time, the outer wall of the positioning frame 4 should be coaxial with the bending line of the sheet metal, thus realizing the bending of the sheet metal. The limit is set, and then the second hydraulic cylinder 7 is activated. The piston rod of the second hydraulic cylinder 7 will push the connecting frame 8 to move upward. The extrusion block 9 will be moved upward by the connecting frame 8 until the extrusion block 9 passes through the limit groove 6 and is in contact with the bottom surface of the plate. The extrusion block 9 will continue to move upward. The plate will deform due to the pressure of the extrusion block 9. Due to the limit of the positioning frame 4, it will bend at the bending line. Due to the arc design of the extrusion block 9 and the smoothness of its own material, the plate will slide on the top surface of the extrusion block 9 when bending, avoiding damage to the plate during bending.

[0038] S2: Before placing the board, adjust the first slide rail 11 according to the length of the board, so that the first slide rail 11 slides on the surface of the second slide rail 12 until it slides to an appropriate distance. Then, insert the second pin 14 into the corresponding positioning hole on the surface of the second slide rail 12, thereby adjusting the position of the first slide rail 11. The movement of the first slide rail 11 will drive the two positioning plates 10 to move accordingly. After the position of the first slide rail 11 is adjusted, move the positions of the two positioning plates 10 so that the two positioning plates 10 slide synchronously on the surface of the first slide rail 11, thereby changing the distance between the two positioning plates 10. After adjusting to the appropriate position, insert the first pin 13 into the positioning hole on the bottom surface of the first slide rail 11 to limit the position of the positioning plate 10. Since the two sets of pin holes are symmetrically arranged, the position of the other positioning plate 10 can be adjusted by the positioning pin hole of one positioning plate 10, thereby achieving symmetrical adjustment. Then, when placing the board, make one side of the board fit against the two positioning plates 10, thus limiting the board.

[0039] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
