Description

Technical Field

[0001] This utility model relates to the technical field of uninterruptible power supply (UPS) production equipment, specifically a molding device for UPS production. Background Technology

[0002] In modern power systems and information technology industries, uninterruptible power supplies (UPS) serve as core power protection equipment to ensure the stable operation of critical equipment. Their applications cover fields with extremely high requirements for power supply continuity, such as data centers, industrial control, medical equipment, and communication base stations. By integrating power conversion, energy storage, and power supply protection functions, UPS can switch to battery power in milliseconds when the power grid experiences anomalies such as power outages, voltage surges / dips, or harmonic interference, thus preventing data loss, equipment damage, and business interruptions. It is a "power safety barrier" for modern infrastructure. UPS mainly consists of a circuit system and a structural system. The structural system, as the "skeleton," is responsible for fixing components, protecting core circuits, and ensuring equipment stability. It includes components such as the casing, internal support, battery compartment, and operation panel. The key processes in its production, such as uncoiling and leveling of rolls, CNC punching, punching, deburring, bending and forming, and online final testing, directly determine the assembly quality and production cycle of UPS, and have a significant impact on product performance and reliability.

[0003] In the internal support design of UPS structural systems, to accommodate the installation requirements of various internal electronic components, optimize space layout, and improve assembly convenience, the industry commonly adopts a π-shaped structural design. This π-shaped structure, through the combination of a top plane and two L-shaped vertical surfaces, provides a stable mounting platform for components. It facilitates fixing components to the internal cavity and top plane of the π-support, effectively utilizes the internal space of the equipment, reduces interference between components, and simplifies assembly processes, leading to its widespread application in actual production.

[0004] However, the current process for bending and forming the π-shaped internal support structure suffers from significant efficiency bottlenecks. Because the π-shaped structure requires a complete top plane and two L-shaped vertical facades, traditional bending processes necessitate four independent bending operations on the metal sheet: first, bending one facade; second, adjusting the sheet angle and bending the other facade; and finally, a second bending of the edges of both facades to ensure structural stability, ultimately forming the complete π-shaped structure. These four bending operations not only require multiple adjustments to the sheet's positioning on the bending equipment, increasing operational complexity, but also significantly extend the bending and forming time for a single support structure, severely restricting the overall production efficiency of the UPS internal support structure and making it difficult to meet the demands of large-scale mass production. Furthermore, multiple bending operations can lead to dimensional inaccuracies in the support structure due to accumulated positioning errors, affecting the assembly accuracy of subsequent components and even increasing the product defect rate, imposing additional cost burdens on manufacturers. Therefore, we propose a forming device for uninterruptible power supply (UPS) production to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a forming device for the production of uninterruptible power supplies (UPS) to solve the problem mentioned in the background art, which is that the internal support bending process is cumbersome and the production efficiency caused by the traditional four-bending process is low, which has become a key factor restricting the production of UPS structural components.

[0006] This utility model provides the following technical solution: A forming device for uninterruptible power supply (UPS) production includes a workbench, a protective frame, a control cabinet, and an integrated bending forming device disposed inside the protective frame. The integrated bending forming device consists of a bending component and a driving component. A fixing frame is fixedly installed on the top of the workbench. The protective frame is a rectangular frame structure with an opening on one side, and the protective frame is fixed to the workbench surface inside the fixing frame. The control cabinet is fixed to the top of the fixing frame near the protective frame and is used to control the operation of the integrated bending forming device. The bending component includes a forming seat, a guide plate, a forming plate, a shaft, a support plate, and a support base. The forming plate is L-shaped, and its L-shaped bend is machined with a chamfered arc structure. The forming seat is an inverted U-shaped structure, with symmetrical mounting grooves on its two side walls. The forming plate is rotatably assembled into the mounting grooves via the shaft, and can rotate around the shaft from 0° to 90°. The support plate is horizontally set at the bottom of the forming seat, and a sliding groove adapted to the two side walls of the forming seat is formed through the support plate. The two side walls of the forming seat extend through the sliding groove to the bottom of the support plate, and the forming seat can slide up and down along the sliding groove.

[0007] Preferably, the support base is fixed to the bottom of the support plate, and the support base is symmetrically provided with through grooves corresponding to the positions of the slide grooves, and the bottom of the two side walls of the forming base extends through the through grooves to the bottom of the support base.

[0008] Preferably, the guide plate is vertically disposed on the top of one of the shorter sides of the molding seat, and the guide plate slides through the bottom of the molding seat and is fixedly connected to the top of the support seat, which is used to guide and limit the sliding direction of the molding seat.

[0009] Preferably, the driving component includes a driving cylinder, a guide rod, a limiting block, and a bending plate. The bending plate has an inverted U-shaped structure adapted to the forming seat, and the inner wall of the bending plate is clearance-fitted with the outer wall of the forming seat. The driving cylinder is fixed at the center of the top of the protective frame, and its bottom output end extends through the protective frame into the interior of the protective frame. The bending plate is fixedly sleeved on the outer wall of the bottom output end of the driving cylinder and moves up and down synchronously with the output end of the driving cylinder. The limiting block is horizontally positioned directly above the molding seat, with its bottom fitting to the top of the molding seat. The guide rod is fixedly installed at the top center of the limiting block, and its top slides through the bottom output end of the drive cylinder and extends into the drive cylinder. A first limiting ring is fixedly provided on the top of the guide rod inside the drive cylinder, and a second limiting ring is fixedly provided on the inner wall of the drive cylinder output end below the first limiting ring. The first and second limiting rings cooperate to limit the sliding stroke of the guide rod. In the initial state, the bottom of the limiting block and the bottom of the molding seat are on the same horizontal plane.

[0010] Preferably, the protective frame has an openable protective door hinged to the open side, and the protective door is equipped with a transparent observation window and a safety lock, which facilitates observation of the bending process and prevents accidental contact with moving parts during operation.

[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] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0024] Please see Figure 1 and Figure 2 As shown, a forming device for uninterruptible power supply production includes a workbench 1, a protective frame 2, a control cabinet 3, and an integrated bending forming device 4 located inside the protective frame 2. The integrated bending forming device 4 consists of a bending component 41 and a driving component 42. A fixed frame 11 is fixedly installed on the top of the workbench 1. The protective frame 2 is a rectangular frame structure with an opening on one side, and the protective frame 2 is fixed to the workbench 1 surface inside the fixed frame 11. The control cabinet 3 is fixed to the top of the fixed frame 11 on the side near the protective frame 2 and is used to control the operation of the integrated bending forming device 4. The four corners of the bottom of the workbench 1 are detachably equipped with universal wheels with brakes, and a push handle is fixedly provided on one side of the protective frame 2 to facilitate the overall movement and fixation of the device. An openable protective door is hinged to the open side of the protective frame 2. The protective door is equipped with a transparent observation window and a safety lock, which facilitates observation of the bending process and prevents accidental contact with moving parts during operation, thereby improving operational safety. The control cabinet 3 has a touch screen display 31 and an emergency stop button 32 on the front. The touch screen display 31 is used to set bending parameters and display the equipment operating status, while the emergency stop button 32 is used to cut off the power to the equipment in an emergency, making the operation more convenient and intelligent.

[0025] Please see Figure 2 - Figure 6 As shown, the bending component 41 includes a forming seat 411, a guide plate 412, a forming plate 413, a shaft 414, a support plate 415, and a support base 416. The forming plate 413 is L-shaped, and its L-shaped bend has a chamfered arc structure. The top near the outer wall has an arc structure. When the inverted U-shaped bending plate 424 moves downward to bend the inner support plate, the bending plate 424 presses the arc structure on the top outer wall of the forming plate 413. At this time, the forming plate 413 rotates around the shaft 414 and bends at the chamfered arc structure of the L-shaped bend. This chamfered arc structure can avoid scratching the plate during bending and reduce stress concentration. At the same time, the chamfered arc structure can perform one-piece bending (see Appendix). Figure 3 and Figure 6 (As shown); the molding seat 411 has an inverted U-shaped structure, with symmetrical mounting grooves 4111 on its two side walls. The molding plate 413 is rotatably assembled in the mounting groove 4111 via the shaft 414, and can rotate 0°-90° around the shaft 414. The support plate 415 is horizontally set at the bottom of the molding seat 411, and a sliding groove 4151 adapted to the two side walls of the molding seat 411 is opened through the support plate 415. The two side walls of the molding seat 411 extend through the sliding groove 4151 to the bottom of the support plate 415, and the molding seat 411 can slide up and down along the sliding groove 4151.

[0026] The support base 416 is fixed to the bottom of the support plate 415, and the support base 416 has symmetrical through slots 4161 corresponding to the positions of the slide grooves 4151. The bottom of the two side walls of the forming base 411 extends through the through slots 4161 to the bottom of the support base 416. The guide plate 412 is vertically set on the top of one of the shorter sides of the forming base 411, and the guide plate 412 slides through the bottom of the forming base 411 and is fixedly connected to the top of the support base 416. It is used to guide and limit the sliding direction of the forming base 411 to ensure the stability of the forming base 411 when sliding. The top two sides of the support plate 415 can be symmetrically provided with positioning blocks for positioning metal plates. The positioning blocks are parallel to the side walls of the forming base 411, and the spacing between the positioning blocks is adapted to the width of the plate to be bent to ensure the consistency of the plate placement position.

[0027] The driving component 42 includes a driving cylinder 421, a guide rod 422, a limiting block 423, and a bending plate 424. The bending plate 424 has an inverted U-shaped structure adapted to the forming seat 411, and the inner wall of the bending plate 424 is clearance-fitted with the outer wall of the forming seat 411. The lower outer wall of the bending plate 424 is provided with a ramp structure to facilitate bending of the metal sheet (see Appendix). Figure 4 (As shown); the drive cylinder 421 is fixed at the top center of the protective frame 2, and its bottom output end extends through the protective frame 2 into the interior of the protective frame 2. The bending plate 424 is fixedly sleeved on the outer wall of the bottom output end of the drive cylinder 421 and moves up and down synchronously with the output end of the drive cylinder 421; the limiting block 423 is horizontally set directly above the forming seat 411, and the bottom of the limiting block 423 is adapted to the top of the forming seat 411; the guide rod 422 is fixedly installed at the top center of the limiting block 423, and the top of the guide rod 422 slides through the bottom output end of the drive cylinder 421 and extends into the interior of the drive cylinder 421; the top of the guide rod 422 located inside the drive cylinder 421 is fixedly provided with a first limiting ring 425, and the first limiting ring 425 is located at the top of the first limiting ring 422. A second limiting ring 426 is fixedly provided on the inner wall of the output end of the drive cylinder 421 below 25. The first limiting ring 425 and the second limiting ring 426 cooperate to limit the sliding stroke of the guide rod 422. In the initial state, the bottom of the limiting block 423 and the bottom of the forming seat 411 are on the same horizontal plane. Since the top of the limiting block 423 slides inside the drive cylinder 421 through the guide rod 422, when the drive cylinder 421 drives the bending plate 424 and the limiting block 423 to move downward, the bottom of the limiting block 423 limits the metal plate to be bent on the top of the forming seat 411 to prevent displacement. As the drive cylinder 421 continues to drive the bending plate 424 to move downward, the bending plate 424 bends the metal plate.

[0028] Workflow: During use, the metal sheet to be bent is placed on the forming base 411 and positioned by the positioning block, ensuring the sheet is directly above the forming base 411. Then, the drive cylinder 421 is activated via the control cabinet 3. Since the top of the limiting block 423 slides inside the drive cylinder 421 via the guide rod 422, as the drive cylinder 421 moves the bending plate 424 and the limiting block 423 downwards, the bottom of the limiting block 423 limits the metal sheet to be bent at the top of the forming base 411, preventing displacement. As the drive cylinder 421 continues to move the bending plate 424 downwards... During the movement, the bending plate 424 bends the metal sheet. After bending, the bending plate 424 continues to move downward, pushing the forming seat 411 to slide downward along the slide groove 4151. When the bending plate 424 moves downward, it squeezes the arc-shaped structure on the top outer wall of the forming plate 413. At this time, the forming plate 413 rotates ninety degrees around the shaft 414 and bends at the chamfered arc-shaped structure of the L-shaped bend to form a π-shaped structure. During the bending process, the bending situation can be observed through the transparent observation window on the protective door. In case of emergency, the emergency stop button 32 can be pressed to cut off the power supply of the equipment.

[0029] This application integrates the traditional four independent bending operations using an integrated bending and forming device 4, eliminating the need for multiple adjustments to the positioning of the sheet metal on the bending equipment. This significantly reduces the bending and forming time of a single support, meets the efficiency requirements of large-scale mass production, and solves the problems existing in traditional bending processes.
