Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing, and in particular to an auxiliary tooling for sheet metal bending equipment. Background Technology

[0002] Sheet metal refers to thin metal sheets (usually less than 6mm) that are processed into the required parts or products through processes such as cutting, stamping, bending, and welding. Bending is one of the core processes in sheet metal processing, and its main purposes include shaping, increasing strength, saving costs, and ensuring safety and aesthetics.

[0003] Currently, when bending sheet metal parts, workers need to place the sheet metal in the bending position of the bending equipment and then manually support it. The sheet metal is bent while the bending equipment is pressing down. However, this operation can easily crush the worker's hand, posing a certain safety hazard and potentially causing injury. Summary of the Invention

[0004] The purpose of this application is to provide an auxiliary tooling for sheet metal bending equipment to solve the problems mentioned in the background art.

[0005] The auxiliary tooling for sheet metal bending equipment provided in this application adopts the following technical solution: it includes a base, a placement frame disposed on the top surface of the base, at least two sets of rollers are installed on the bottom surface of the placement frame, an upper pressure plate is connected to the top surface of the placement frame, a set of reinforcing mechanisms is provided at the front end of the upper pressure plate, a bearing platform is connected to the front end of the base, a support frame is provided on the top surface of the bearing platform, and a set of lifting plates is hinged to the top surface of the support frame; The rear end of the base is connected to a set of rear bases. A set of hydraulic push rods is provided at the top center of the rear bases. A set of telescopic cylinders is provided at the left and right positions of the hydraulic push rods. The top ends of the hydraulic push rods and the telescopic cylinders are connected to the rear end of the bottom surface of the upper pressure plate. At least two sets of extension rods are provided at equal intervals on the bottom surface of the upper pressure plate corresponding to the rear end of the placement frame. A set of placement frames is provided at both the front and rear ends of the top surface of the upper pressure plate. At least two sets of upper pressure rollers are provided on the bottom surface of the upper pressure plate corresponding to the rollers.

[0006] By adopting the above technical solution, the support frame can bend sheet metal parts passing between the placement frame and the upper pressure plate. The lifting plate flexibly adjusts its angle to fit the outer side of the sheet metal part, increasing contact and thus making the support more stable and improving safety during bending. Simultaneously, the reinforcing mechanism strengthens the connection stability between the placement frame and the upper pressure plate, preventing damage to the upper pressure plate due to increased stress during bending, which would affect the clamping effect on the sheet metal part. The upper pressure plate achieves stable lifting and lowering through a hydraulic push rod and a telescopic cylinder, combined with an extension rod to evenly distribute pressure, ensuring stable clamping of the sheet metal part within the placement frame. This system can accommodate sheet metal parts of different sizes and thicknesses. Furthermore, the rollers on the bottom surface of the placement frame cooperate with the upper pressure rollers at the bottom of the upper pressure plate to form rolling contact, reducing frictional resistance during sheet metal part movement, facilitating smooth pushing of the sheet metal part, achieving efficient material transfer, and improving processing efficiency.

[0007] Preferably, the reinforcing mechanism includes a connecting seat, a connecting rod, a driving mechanism, a screw rod, and a fixing sleeve. The upper pressure plate has a set of connecting seats at its top front end, and a set of connecting rods at the inner end of the connecting seats. The left and right ends of the connecting rods extend to the left and right ends of the connecting seats and are connected to a set of driving mechanisms. The middle end of each driving mechanism is provided with a set of screw rods. The left and right front ends of the base are each provided with a set of fixing sleeves.

[0008] By adopting the above technical solution, the connecting rod can drive the left and right sets of drive mechanisms and the screw to rotate around the connecting seat, which is conducive to the storage of the screw. The screw can be fixed by extending its bottom end into the fixed sleeve, thereby strengthening the upper pressure plate. When the sheet metal parts are bent, the upper pressure plate can be provided with additional support, avoiding damage to the upper pressure plate caused by high-intensity operations, reducing later maintenance costs, and improving production efficiency.

[0009] Preferably, all components of the drive mechanism are identical. The drive mechanism includes a connecting sleeve and a drive compartment. Each end of the connecting rod is provided with a set of connecting sleeves, and the top end of each connecting sleeve is connected to a set of drive compartments.

[0010] By adopting the above technical solution, the connecting sleeve and the drive chamber can rotate around the connecting rod, and the screw can move inside the connecting sleeve through the drive chamber.

[0011] Preferably, the top end of the connecting sleeve extends through to the bottom end of the drive compartment and is connected to a set of driven sleeves. A set of gears is provided on the outer side of the driven sleeve near the top end. A set of drive motors is connected to the end of the drive compartment away from the connecting sleeves. A set of gears is connected to the top end of the drive shaft of the drive motors. Gears two mesh with gears one.

[0012] By adopting the above technical solution, the drive motor transmits power to the driven sleeve through the meshing of gear two and gear one. The driven sleeve drives screw one to rotate, which can ensure efficient power transmission, enhance stability during driving, reduce energy loss, improve response speed, and significantly improve processing efficiency and consistency.

[0013] Preferably, all components of the fixing sleeve are identical. A set of fixing brackets is provided on the outer side of the fixing sleeve away from the base. A set of contact plates is provided on the inner side of the fixing sleeve corresponding to the middle position of the fixing brackets. A set of screw rods is connected to the middle of the outer side of the contact plates. The other end of the screw rods passes through the middle of the fixing brackets and is connected to a set of force-applying brackets.

[0014] By adopting the above technical solution, the rotating force-applying frame can drive the second screw to push the contact plate into the fixed sleeve, thereby clamping and fixing the first screw, and pressing down on the front end of the upper pressure plate, enhancing the overall structural stability and preventing damage to the upper pressure plate under high load bending.

[0015] Preferably, a set of recycling troughs is provided at the middle of the top of the support platform, and a set of hydraulic push rods II is provided at the middle of the recycling troughs. The top of the output end of the hydraulic push rods II is connected to the middle of the bottom surface of the support frame.

[0016] By adopting the above technical solution, the output end of the hydraulic push rod can drive the support frame to move upward, thereby realizing the bending of sheet metal parts, reducing the number of manual steps, and improving the safety during production and processing.

[0017] Preferably, the support frame has a set of extension arms at each of the four ends of its bottom surface, and the recycling trough has storage slots at each of the four ends of its bottom surface corresponding to the extension arms.

[0018] By adopting the above technical solution, the extension arm can improve the stability of the support frame when it moves up and down, and the support frame can be retracted into the recycling tank for easy recycling and processing, reducing the space occupied.

[0019] Preferably, the four ends of the bottom surface of the lifting plate are connected to the four ends of the top surface of the support frame by a set of springs.

[0020] By adopting the above technical solution, when the lifting plate contacts the outer side of the sheet metal part, it can compress the spring at the opposite position to tilt it, and after the bending operation is completed, it will automatically return to its original position by the elastic force of the spring.

[0021] Preferably, both the fixing sleeve and the inner side of the contact plate are provided with internal threads corresponding to the screw, and the contact plate can move horizontally at the inner end of the fixing sleeve.

[0022] By adopting the above technical solution, the connection stability between the screw and the fixed sleeve can be improved through the internal thread, and the contact plate can improve the tightening effect of the internal thread and the screw.

[0023] Preferably, the top surface of the lifting plate is provided with a friction layer.

[0024] By adopting the above technical solution, the friction with sheet metal parts can be increased, which can effectively prevent the sheet metal parts from slipping during bending.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a placement frame set on the top surface of the base, with an upper pressure plate above the placement frame. The upper pressure plate is connected to the placement frame via an extension rod, and the distance between the upper pressure plate and the placement frame can be freely adjusted, thereby adapting to sheet metal parts of different sizes and thicknesses. This can effectively expand the applicability of auxiliary tooling, eliminating the need for frequent disassembly and replacement, and effectively improving work efficiency. 2. This application uses a reinforcing mechanism set at the front end of the upper pressure plate. The reinforcing mechanism includes components such as a connecting seat, a connecting rod, a drive mechanism, a screw, and a fixing sleeve. These components work together to strengthen the front end of the upper pressure plate, enhance its structural strength with the placement frame, prevent the upper pressure plate from being damaged due to excessive stress when bent under high load, and effectively extend the service life of the upper pressure plate. 3. This application uses a support platform set at the front end of the base. The support platform is connected to a set of support frames through a hydraulic push rod. The support frames are pushed upward by the hydraulic push rod to bend the sheet metal parts. During the sheet metal bending operation, it is not necessary to manually support the sheet metal parts, which can effectively improve production safety. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0028] An auxiliary tooling for sheet metal bending equipment, as shown in the reference. Figure 1 and Figure 6 The system includes a base 1, an "L"-shaped mounting frame 2 fixedly connected to the top surface of the base 1, and at least two sets of rollers 3 installed on the inner bottom surface of the mounting frame 2 to facilitate the movement and transportation of sheet metal parts on the mounting frame 2. An upper pressure plate 4 is installed on the top surface of the mounting frame 2, and a set of reinforcing mechanisms 5 are connected to the front end of the upper pressure plate 4. A support platform 6 is fixedly connected to the front end of the base 1, and a support frame 7 is connected to the top surface of the support platform 6. A set of lifting plates 71 is hinged to the top surface of the support frame 7, wherein each of the four ends of the bottom surface of the lifting plate 71 is connected to the support frame by a set of springs. 7. The top surface is connected at four ends. When the lifting plate 71 contacts the outer side of the sheet metal part, it can squeeze the spring at the corresponding position to tilt it, so as to better contact the outer side of the sheet metal part. After the bending operation is completed, it will automatically return to its original position by the elastic force of the spring, which improves the flexibility of use and eliminates the need for manual reset, making it convenient for the next bending operation. In addition, a set of friction layers made of rubber is fixedly connected to the top surface of the lifting plate 71, which can increase the friction between the lifting plate 71 and the sheet metal part, effectively preventing the sheet metal part from slipping during the bending process and improving the safety of processing.

[0029] Specifically, the support frame 7 can bend the sheet metal parts that pass between the placement frame 2 and the upper pressure plate 4, and the angle can be flexibly adjusted by the lifting plate 71 to fit the outside of the sheet metal parts, increasing the contact with the sheet metal, thereby making the support of the sheet metal more stable and improving the safety during bending.

[0030] Reference Figure 1 and Figure 2A set of rear bases 41 is fixedly connected to the rear end of the base 1. A set of hydraulic push rods 42 is installed at the top center of the rear bases 41. A set of telescopic cylinders 43 is installed on the left and right sides of the top surface of the rear bases 41 near the hydraulic push rods 42. The top ends of the hydraulic push rods 42 and the telescopic cylinders 43 are fixedly connected to the rear end of the bottom surface of the upper pressure plate 4. The hydraulic push rods 42 can lift the upper pressure plate 4 upward through the output end, adjusting the distance between the upper pressure plate 4 and the placement frame 2. The telescopic cylinders 43 can help improve the stability of the upper pressure plate 4 when it moves, and the bottom surface of the upper pressure plate 4 is correspondingly placed on the placement frame 2. At least two sets of extension rods 44 are fixedly connected at equal intervals at the top and rear ends of the mounting frame 2. The bottom ends of the extension rods 44 can extend to the inner rear end of the mounting frame 2, which can improve the stability of the upper pressure plate 4 when it moves and prevent the upper pressure plate 4 from shifting or misaligning when it moves. A set of mounting frames 45 is fixedly connected to the front and rear ends of the top of the upper pressure plate 4. The top surface of the mounting frames 45 is provided with arc-shaped grooves. After the screw 54 is rotated, it can contact the arc-shaped grooves, which facilitates the placement and storage of the screw 54. At least two sets of upper pressure rollers 46 are installed on the bottom surface of the upper pressure plate 4 at the positions corresponding to the rollers 3.

[0031] Specifically, the upper pressure plate 4 achieves stable lifting and lowering through the hydraulic push rod 42 and the telescopic cylinder 43, and the pressure is evenly distributed by the extension rod 44 to ensure stable clamping of the sheet metal parts in the placement frame 2. It can adapt to sheet metal parts of different sizes and thicknesses. The rollers 3 on the bottom surface of the placement frame 2 cooperate with the upper pressure rollers 46 at the bottom of the upper pressure plate 4 to form rolling contact, which can reduce the frictional resistance when the sheet metal parts move, which is conducive to the smooth pushing of the sheet metal parts, realizes efficient material transfer, and improves processing efficiency.

[0032] Reference Figure 3 The reinforcing mechanism 5 includes a connecting seat 51, a connecting rod 52, a driving mechanism 53, a screw 54, and a fixing sleeve 55. A set of connecting seats 51 is fixedly connected to the top front end of the upper pressure plate 4. A set of connecting rods 52 is rotatably connected to the inner end of the connecting seat 51. The left and right ends of the connecting rods 52 extend to the left and right ends of the connecting seat 51 and are fixedly connected to a set of driving mechanisms 53. A set of screws 54 is provided in the middle of each driving mechanism 53. A set of fixing sleeves 55 corresponding to screws 54 is fixedly connected to the front ends of the left and right sides of the base 1.

[0033] Specifically, the connecting rod 52 can drive the left and right sets of drive mechanisms 53 and screw 54 to rotate around the connecting seat 51, so that screw 54 is parallel to the upper pressure plate 4 and its top can contact the placement frame 45, which is conducive to the storage of screw 54. Screw 54 can be fixed by extending its bottom end into the fixing sleeve 55, thereby strengthening the upper pressure plate 4. When the sheet metal part is bent, it can provide additional support for the upper pressure plate 4, avoid damage to the upper pressure plate 4 caused by high-intensity operation, reduce later maintenance costs, and improve production efficiency.

[0034] Reference Figure 3All components of the drive mechanism 53 are the same. The drive mechanism 53 includes a connecting sleeve 531 and a drive chamber 532. Both ends of the connecting rod 52 are fixedly connected to a set of connecting sleeves 531, which can drive the two sets of connecting sleeves 531 to rotate synchronously. The top of the connecting sleeve 531 is fixedly connected to a set of drive chambers 532.

[0035] Specifically, the connecting sleeve 531 and the drive chamber 532 can rotate around the connecting rod 52, and the screw 54 can move within the connecting sleeve 531 through the drive chamber 532.

[0036] Reference Figure 4 The top end of the connecting sleeve 531 extends through to the bottom end of the drive compartment 532 and is rotatably connected to a set of driven sleeves 5321. The inner side of the driven sleeve 5321 is provided with an internal thread corresponding to the screw 54. When the driven sleeve 5321 rotates, it can drive the screw 54 to move up and down. A set of gears 5322 is embedded in the outer side of the driven sleeve 5321 near the top end. A set of drive motors 5323 is installed in the drive compartment 532 at the end away from the connecting sleeve 531. A set of gears 5324 is fixedly connected to the top end of the drive shaft of the drive motor 5323. Gears 5324 mesh with gears 5322. The drive motor 5323 can drive gears 5324 and driven sleeve 5321 to rotate through gears 5322.

[0037] Specifically, the drive motor 5323 transmits power to the driven sleeve 5321 through the meshing of gear 2 5324 and gear 1 5322. The driven sleeve 5321 drives the screw 1 54 to rotate, thereby moving it up and down. This ensures efficient power transmission, enhances stability during driving, reduces energy loss, improves response speed, and significantly improves processing efficiency and consistency.

A set of contact plates 552 is slidably connected to the inner side of the fixing sleeve 55 at a position corresponding to the middle of the fixing brackets 551. The contact plates 552 can extend into the fixing sleeve 55. Both the inner sides of the fixing sleeve 55 and the contact plates 552 are provided with internal threads corresponding to the screw 54. The screw 54 can improve the connection stability with the fixed sleeve 55 through the internal thread. The contact plate 552 can improve the tightening effect of the internal thread and the screw 54. A set of screws 553 is rotatably connected to the outer middle end of the contact plate 552. The other end of the screw 553 passes through the middle end of the fixed frame 551 and is fixedly connected to a set of force-applying frames 554. The middle end of the fixed frame 551 is provided with an internal thread hole corresponding to the screw 553. When the screw 553 rotates, it can move left and right in the internal thread hole.

[0039] Specifically, the rotating force application frame 554 can drive the second screw 553 to push the contact plate 552 into the fixed sleeve 55, thereby clamping and fixing the first screw 54, and pressing down on the front end of the upper pressure plate 4, enhancing the overall structural stability and preventing the upper pressure plate 4 from being damaged under high load bending.

Furthermore, a set of extension arms is fixedly connected to the four ends of the bottom surface of the support frame 7. The four ends of the bottom surface of the recycling trough 61 are provided with corresponding storage slots for the extension arms. The extension arms can be retracted into the storage slots. The extension arms can improve the stability of the support frame 7 when it moves up and down, and facilitate recycling and reduce the space occupied.

[0041] Specifically, the output end of the hydraulic push rod 62 can drive the support frame 7 to move upward, thereby realizing the bending of the sheet metal parts, reducing the number of manual steps, and improving the safety during production and processing.

[0042] This application provides an auxiliary tooling for sheet metal bending equipment. A placement frame 2 is mounted on the top surface of a base 1, and an upper pressure plate 4 is positioned above the placement frame 2. The upper pressure plate 4 is connected to the placement frame 2 via an extension rod 44. The distance between the upper pressure plate 4 and the placement frame 2 can be freely adjusted, thus accommodating sheet metal parts of different sizes and thicknesses. This effectively expands the applicability of the auxiliary tooling, eliminating the need for frequent disassembly and replacement, and significantly improving work efficiency. A reinforcing mechanism 5 is located at the front end of the upper pressure plate 4. The reinforcing mechanism 5 includes a connecting seat 51, a connecting rod 52, a drive mechanism 53, and a screw. The components 54 and 55, together with each other, can strengthen the front end of the upper pressure plate 4, enhance its structural strength with the placement frame 2, and prevent the upper pressure plate 4 from being damaged due to excessive stress during high-load bending, thus effectively extending the service life of the upper pressure plate 4. The support platform 6 set at the front end of the base 1 is connected to a set of support frames 7 by hydraulic push rod 62. The support frames 7 are pushed upward by hydraulic push rod 62 to bend the sheet metal parts.
