Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an adjustment structure for a bending machine. Background Technology

[0002] Bending machines are essential equipment in sheet metal processing, primarily used to press steel plates into parts of various shapes. Their working principle involves using hydraulic or mechanical force and molds to bend metal sheets into the desired shape. Bending machines are widely used in various industries, including automotive, aircraft manufacturing, light industry, shipbuilding, container manufacturing, elevators, and railway vehicles.

[0003] Existing bending machines typically use dies fixed to the worktable via positioning devices. When a different die is needed, the existing die must be removed before replacement, resulting in numerous steps and significant time consumption, thus reducing processing efficiency. Furthermore, existing dies usually only have one available bending groove, failing to fully utilize the die's structural characteristics to create more bending grooves, making them unsuitable for increasingly complex processing requirements. Therefore, the inventors have improved the adjustment structure of the bending machine. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustment structure for a bending machine. This adjustment structure has the advantages of simple structure, reasonable design, quick mold switching without disassembling the mold, high degree of automation, improved processing efficiency, and the ability to switch between different working surfaces by rotation. Furthermore, the bending processing grooves on each working surface have different shapes, which adapts to increasingly complex processing needs and solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustment structure for a bending machine, comprising a base and a drive device mounted on the base. The base includes a working platform and a mounting bracket fixed to the upper surface of the working platform. The mounting bracket is used to mount the bending device. A mounting groove is provided on the lower surface of the working platform, and a top groove is provided on the upper surface of the working platform. The drive device includes a reducer and a motor mounted at the bottom of the reducer. Two sprockets are provided on the top of the reducer and connected by a chain. One sprocket is connected to the reducer, and a rotating shaft is connected to the other sprocket. The rotating shaft is located in the top groove and mounted on the working platform. A positioning plate is coaxially connected to the top of the rotating shaft. A central support block is fixed at the center of the upper surface of the positioning plate, and multiple rotatable molds are connected to the central support block. The multiple molds are distributed in the circumferential direction of the positioning plate.

[0006] Preferably, a crossbeam plate is fixed in the mounting slot, and the reducer is installed on the lower end face of the crossbeam plate, thus ensuring the structural stability of the reducer and the motor.

[0007] Preferably, the chain and the two sprockets are both located in the mounting slot, and the two sprockets are both mounted on the bottom of the work platform.

[0008] Preferably, the mold includes a body with multiple working surfaces, each with a bending groove. The bending grooves have different shapes to accommodate the bending requirements of different workpieces. By changing the bending grooves, workpieces of different shapes can be bent out.

[0009] Preferably, a connecting shaft is provided at one end of the main body near the central support block. The main body is connected to the central support block through the connecting shaft, so the main body can rotate with the connecting shaft, thereby calling different working surfaces.

[0010] Preferably, the bending groove is V-shaped, and an included angle is formed between the two inner walls of the bending groove. The value of this included angle is between 75° and 115°. Therefore, by using different bending grooves, workpieces of different shapes can be folded out.

[0025] Please see Figure 1 The present invention provides an embodiment of an adjustment structure for a bending machine, which includes a base 1 and a drive device 2 disposed on the base 1. The overall structure is simple and the design is reasonable.

[0026] Please see Figure 2The base 1 includes a working platform 11, with a mounting groove 13 on the lower end face of the working platform 11. A crossbeam plate 14 is fixed in the mounting groove 13. A top groove 15 is provided on the upper end face of the working platform 11. The drive device 2 includes a reducer 21 and a motor 22 located at the bottom of the reducer 21. The reducer 21 is mounted on the lower end face of the crossbeam plate 14, thus ensuring the structural stability of the reducer 21 and the motor 22. Two sprockets 23 are provided on the top of the reducer 21. The sprockets 23 are connected by a chain 24. One of the sprockets 23 is connected to the reducer 21, and the other sprocket 23 is connected to a shaft 25. The chain 24 and the two sprockets 23 are both located in the mounting groove 13, and the two sprockets 23 are both installed at the bottom of the working platform 11. The shaft 25 is located in the top groove 15 and is installed on the working platform 11. A positioning plate 26 is coaxially connected to the top of the shaft 25, and a central support block 27 is fixed at the center of the upper surface of the positioning plate 26.

[0027] Please see Figure 3 The upper end face of the working platform 11 is fixed with a mounting bracket 12, which is used to install the bending device. Multiple rotatable molds 28 are connected to the central support block 27, and the multiple molds 28 are distributed in the circumferential direction of the positioning plate 26.

[0028] Please see Figure 4 The mold 28 includes a body 281, on which multiple working surfaces are provided. Each of the multiple working surfaces has a bending groove 282. The shapes of the multiple bending grooves 282 are different, so as to adapt to the bending requirements of different workpieces. By changing different bending grooves 282, workpieces of different shapes can be bent out. A connecting shaft 283 is provided at one end of the body 281 near the central support block 27. The body 281 is connected to the central support block 27 through the connecting shaft 283. Therefore, the body 281 can rotate with the connecting shaft 283, thereby calling different working surfaces. The bending groove 282 is V-shaped, and an included angle is formed between the two inner walls of the bending groove 282. The value of the included angle is between 75° and 115°. Therefore, by calling different bending grooves 282, workpieces of different shapes can be bent out.

[0029] Please see Figure 5 The driving device 2 also includes multiple sets of support components 29, which are respectively disposed below multiple molds 28. Each support component 29 includes a cylinder 291 and a support block 292 connected to the output end of the cylinder 291. The cylinder 291 is fixed to the lower end face of the positioning plate 26. A gasket 293 is fixedly bonded to the upper end face of the support block 292. The gasket 293 is in contact with the body 281. In this embodiment, the gasket 293 is made of rubber and is used to directly contact the body 281 and support the body 281 to keep the bending processing groove 282 stable.

[0030] Working principle: Please refer to the following again. Figures 1 to 5 The bending device is mounted on the mounting bracket 12. In operation, the workpiece is placed on the mold 28 below the bending device, and the bending device is driven to work. The bending processing groove 282 on the main body 281 can be used to bend the workpiece. When it is necessary to switch molds 28, the drive motor 22 is driven to run, and the sprocket 23 and chain 24 drive the rotating shaft 25 to rotate, so that the positioning plate 26 drives the central support block 27 and multiple molds 28 to rotate, thereby switching different molds 28. In addition, the multiple bending processing grooves 282 on each main body 281 can be selected as needed. When selecting, first, the cylinder 291 is driven to work and drive the pad 293 to separate from the main body 281. Then, the main body 281 is rotated 90°, 180° or 270° along the connecting shaft 283 to switch different bending processing grooves 282. Then, the support block 292 supports the main body 281 to ensure the balance and structural stability of the main body 281.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
