Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, and in particular to a sheet metal bending device for a JP cabinet integrated power distribution box. Background Technology

[0002] With the continuous development of power systems, JP (Power Distribution Box) integrated distribution boxes, as important outdoor power distribution equipment, are widely used in rural power grid upgrades and urban power distribution systems. JP box enclosures are mostly made of cold-rolled steel plates or galvanized steel plates, and the sheet metal processing technology directly affects the structural strength and appearance quality of the enclosure. To meet the demands of complex JP box structures and mass production, sheet metal bending devices have become an indispensable core piece of equipment in the distribution box manufacturing process. These devices enable precise bending and forming of metal sheets, ensuring consistent dimensions and tight connections among all components, thereby improving the overall performance and service life of the distribution box.

[0003] Currently, traditional sheet metal bending equipment for JP cabinet integrated distribution boxes mostly uses hydraulic bending machines or CNC bending machines, typically consisting of a frame, bending dies, a pressing mechanism, and a transmission system. During operation, the upper die is driven downwards by hydraulic pressure or a motor, causing the metal sheet to bend between the upper and lower dies, thus achieving straight-line or multi-angle bending processing. To meet the processing needs of sheet metal parts of different specifications and shapes, the equipment is equipped with detachable and replaceable bending cutters and positioning mechanisms, facilitating adaptation to different processing tasks and improving production flexibility and processing efficiency.

[0004] However, existing sheet metal bending devices suffer from unreasonable structural design issues in practical applications, particularly the cumbersome replacement of bending cutters. Traditional equipment typically requires repeatedly loosening and disassembling multiple sets of screws using tools when changing the bending cutter head. This complex and time-consuming operation leads to lengthy equipment adjustments, reduced production efficiency, increased operator workload, and is detrimental to the demands of mass production and rapid manufacturing. Therefore, there is an urgent need to design a sheet metal bending device that facilitates quick and easy bending cutter head replacement to improve operational convenience and equipment usability during production.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a sheet metal bending device for a JP cabinet integrated distribution box, including a base 1. A top plate 2 is fixedly connected to the top of the base 1. The top plate 2 supports and fixes various components to ensure the overall structural stability of the device. A driving assembly is provided on the outer wall of the top plate 2 to provide power for the bending process, making the bending operation more labor-saving and efficient. An installation rod 5 is provided on one side of the top plate 2. The installation rod 5 connects to and supports the installation plate 7, providing a stable running trajectory for the bending head 6. The installation plate 7 is slidably connected inside the installation rod 5. 7 can slide along the inside of the mounting rod 5, making it easy to adjust the position of the bending head 6 to adapt to different sizes of plates. The bottom of the mounting plate 7 is fixedly connected to the bending head 6, which is used to bend the sheet metal plates to ensure that the bending process is accurate and the forming effect is good. The top of the base 1 is fixedly connected to the lower mold 4, which works with the bending head 6 to support the plate and form the bending angle, ensuring the bending forming accuracy. The mounting rod 5 is equipped with a connecting component, which is used to reliably connect the mounting plate 7 and the mounting rod 5, making it easy to replace and fix the bending head 6.

[0033] The connecting assembly includes a mounting pin 8, which serves as a connecting and limiting component to ensure the stability and reliability of the mounting plate 7 during operation. The mounting plate 7 has an internal mounting groove 12, providing a fitting space for the mounting pin 8 and the ball 11, ensuring the stability and detachability of the connecting assembly. The mounting pin 8 passes through the mounting rod 5 and the mounting plate 7, forming a detachable connection between the mounting plate 7 and the mounting rod 5, facilitating the removal and replacement of the bending head 6. The mounting pin 8 contains a ball 11, which fits into the mounting groove 12. The ball 11, through its cooperation with the mounting groove 12, serves to limit and position the mounting pin 8, ensuring accurate positioning. The mounting pin 8 has an internal threaded connection to a mounting bolt 9, which is used for fixing and adjustment. Install pin 8 to ensure a firm connection. One end of mounting bolt 9 is fixedly connected to cone 10. Cone 10 is used to cooperate with ball 11 to achieve limiting and fixing functions, preventing the connection components from loosening. The outer wall of cone 10 fits against ball 11. The fitting structure of cone 10 and ball 11 further improves the stability and reliability of the connection. The drive component includes electric push rod 3. Electric push rod 3 serves as the main power source to drive mounting rod 5 to move up and down. The top of electric push rod 3 is fixedly connected to one side of top plate 2 to ensure the stability of the drive component position and facilitate power transmission. The output end of electric push rod 3 is fixedly connected to the top of mounting rod 5. The extension and retraction of electric push rod 3 drives the movement of mounting rod 5 and mounting plate 7 to realize the lifting and bending operation of bending head 6.

[0034] Reference Figure 3 and Figure 4A limiting plate 13 is fixedly connected to the top of the base 1. The limiting plate 13 provides a support platform for the limiting and clamping structure, ensuring that all components are installed stably. A limiting groove 14 is opened inside the limiting plate 13. The limiting groove 14 provides a sliding channel for the slider 15, ensuring that the slider 15 can move smoothly within the limiting groove 14. The slider 15 is set inside the limiting plate 13. The slider 15, as the main sliding component, moves back and forth within the limiting groove 14 to realize the adjustment and limiting functions of the clamping components. The slider 15 is slidably connected inside the limiting groove 14, ensuring smooth movement of the slider 15 and facilitating position adjustment to adapt to different plate sizes. The device is threaded with a fastening bolt 16, which is used to lock the slider 15 and related structures to prevent displacement after sliding and ensure stable clamping during processing. A slider 2 17 is rotatably connected to one end of the fastening bolt 16. The slider 2 17 rotates with the fastening bolt 16, driving the movement of the locking block 18 to control the clamping state. The locking block 18 is fixedly connected to the outer wall of the slider 2 17. The locking block 18, in conjunction with other structures, serves to lock and limit movement, enhancing the stability and safety of the device. A clamping plate 19 is slidably connected inside the slider 15. The clamping plate 19 can slide and adjust within the slider 15, facilitating the clamping and release of the sheet metal. In operation, a clamping block 20 is fixedly connected to one side of the clamping plate 19. The clamping block 20 is integrally connected to the clamping plate 19, further enhancing the clamping force on the plate. One side of the clamping block 20 fits against the inner wall of the limiting groove 14, and the clamping block 20 and the inner wall of the limiting groove 14 are tightly fitted, effectively preventing the clamping plate 19 from shifting during operation and ensuring reliable clamping. A connecting rod 21 is rotatably connected to the top of the slider 15. The connecting rod 21 acts as a force transmission component, connecting the slider 15 and the pressure rod 22, transmitting the operating force to the pressure rod 22. The pressure rod 22 is rotatably connected to the top of the connecting rod 21. The pressure rod 22 is used to press downward under the drive of the connecting rod 21, realizing the function of pressing and limiting the plate. A support rod 23 is rotatably connected to the top, providing support for the pressure rod 22 and ensuring its stability under stress. The top of the support rod 23 is rotatably connected to one end of the pressure rod 22. Through this rotatable connection, the support rod 23 enables the pressure rod 22 to form a stable support structure when compressed. An L-shaped rod 24 is rotatably connected to one end of the support rod 23. The L-shaped rod 24 can be flexibly adjusted in angle through rotatable connection, assisting in the operation of the support and limiting devices. A limiting wheel 25 is rotatably connected inside the L-shaped rod 24. The limiting wheel 25 serves as a guide and limiter, restricting the range of motion with the cooperation of the L-shaped rod 24 to ensure reliable and safe movement of each structure.

[0035] Working principle: When using the sheet metal bending device of the JP cabinet integrated distribution box, if it is necessary to replace the bending head 6, simply loosen the mounting bolt 9, then the cone 10 and the ball 11 separate, then the ball 11 can slide in the mounting pin 8, then the ball 11 separates from the mounting groove 12, then the mounting pin 8 separates from the mounting plate 7 and the mounting rod 5, and then the bending head 6 is replaced by separating it from the mounting plate 7 and the mounting rod 5. When bending, the output end of the electric push rod 3 extends and drives the bottom bending head 6 to press down through the mounting rod 5, driving the sheet metal to be embedded in the lower mold 4 for bending, thus achieving the effect of facilitating the replacement of the bending head.

[0036] When sheet metal needs to be limited, adjust the position of slider 15 within the limiting plate 13. Once in position, rotate the fastening bolt 16 so that the fastening bolt 16 drives the locking block 18 through slider 2 17 into slider 15. Then, the outer wall of the locking block 18 adheres to the clamping plate 19, causing the clamping plate 19 to extend out of slider 15. The clamping plate 19 is then fixed to the inner wall of the limiting groove 14 by the clamping block 20. Subsequently, the pressing rod 22 is pressed down, causing one end of the support rod 23 to lift and the other end to press down. Then, the support rod 23 drives the limiting wheel 25 to adhere to the outer wall of the sheet metal through the L-shaped rod 24. Subsequently, the pressing rod 22 and slider 15 are connected and limited by the connecting rod 21, so that the pressing rod 22 and the support rod 23 are in a straight line and self-locking, achieving the effect of limiting the sheet metal.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
