Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of servo bending machine technology, and more specifically, to a pump-controlled servo bending machine. Background Technology

[0002] Pump-controlled servo bending machines are high-precision bending equipment driven by a pump-controlled servo system. The hydraulic pump is directly driven by a servo motor, which features energy saving, accurate positioning, fast response, stable operation and low noise. They are suitable for batch processing of precision sheet metal such as electronic housings and automotive parts, and are also suitable for workshop environments with requirements for energy consumption and noise.

[0003] When using existing pump-controlled servo bending machines, especially when bending smaller sheets, operators need to hold the sheet and place it into the bending machine for bending. During this process, when the two bending dies contact the sheet, the edges of the sheet are prone to swaying, which can cause the sheet to deviate during the swaying process. This can lead to poor bending results and, in severe cases, affect the yield of the finished sheet. Utility Model Content

[0022] like Figures 1-4 As shown, a pump-controlled servo bending machine according to an embodiment of this disclosure is illustrated. It includes a bending machine body 1, and further includes: a support plate 2, a clamping plate 3, and a fixing mechanism. Multiple anti-slip strips 15 are fixedly connected to the opposite sides of the two clamping plates 3. Two support plates 2 are provided, and the two support plates 2 are mounted on the bending machine body 1 via a moving mechanism. The moving mechanism drives the two support plates 2 to move back and forth. The clamping plates 3 are mounted on both support plates 2 via a sliding mechanism. The sliding mechanism supports the clamping plates 3 to move with the sheet metal. The fixing mechanism is mounted on the two sliding mechanisms and drives the clamping plates 3 to fix the sheet metal. Through the arrangement of the support plate 2, clamping plate 3, and fixing mechanism, the sheet metal can be clamped and fixed during bending, and it can adapt to the swaying of the sheet metal during bending, increasing the stability of the swaying during bending and preventing deviation, thereby improving the bending effect of the sheet metal and minimizing the impact on the yield rate of the bent sheet metal.

[0023] The moving mechanism includes a fixed frame 4, slide rods 5, and a drive assembly. A slide tube 14 is fixedly connected to the bottom end of the support plate 2, and the slide tube 14 is slidably connected to the slide rod 5. The fixed frame 4 is fixedly connected to one side of the bending machine body 1. Two slide rods 5 are provided; one end of each slide rod 5 is fixedly connected to the fixed frame 4, and the other end is fixedly connected to the bending machine body 1. The drive assembly is mounted on the fixed frame 4 and is used to drive the two support plates 2 to move on the two slide rods 5. The drive assembly includes a connecting frame 6 and a first electric cylinder 7. Both ends of the connecting frame 6 are fixedly connected to the two support plates 2 respectively. The first electric cylinder 7 is installed on one side of the connecting frame 6, and its output end passes through the connecting frame 6 and is fixedly connected to the fixed frame 4. The first electric cylinder 7 drives the connecting frame 6 to move. When the connecting frame 6 moves, it drives the two slide tubes 14 to move on the two slide rods 5, thereby moving the two support plates 2 and consequently the two clamping plates 3, thus adapting to the fixing of plates of different lengths.

[0024] The sliding mechanism includes a guide frame 8, a slide plate 9, and a support assembly. The guide frame 8 is fixedly connected to the support plate 2, the slide plate 9 is slidably connected to the guide frame 8, and the clamping plate 3 is rotatably connected to one side of the slide plate 9. The support assembly is set inside the guide frame 8 to support the slide plate 9 to slide within the guide frame 8. The support assembly includes an arc-shaped rod 10 and a support spring 11. The guide frame 8 has a sliding hole, the arc-shaped rod 10 is slidably connected to the sliding hole, one end of the arc-shaped rod 10 is fixedly connected to the slide plate 9, and the support spring 11 is sleeved on the arc-shaped rod 10. The two ends of the support spring 11 are fixedly connected to the guide frame 8 and the slide plate 9, respectively. When the two clamping plates 3 clamp and fix the two sides of the plate, when the plate swings during the bending process, it will drive the slide plate 9 to slide within the guide frame 8 and slide within the sliding hole through the arc-shaped rod 10. With the support of the support spring 11, the clamping plate 3 moves in the direction of the plate's swing.

[0025] The fixing mechanism includes a push rod 12 and a second electric cylinder 13. The push rod 12 is fixedly connected to the slide plate 9, and the clamping plate 3 is rotatably connected to one end of the push rod 12. The second electric cylinder 13 is installed on one side of the slide plate 9. The output end of the second electric cylinder 13 passes through the slide plate 9 and is fixedly connected to the other end of the push rod 12. The push rod 12 is moved by the second electric cylinder 13. When the push rod 12 moves, it moves the clamping plate 3, thereby clamping and fixing the plate between the two clamping plates 3.

[0026] Working principle: When bending the sheet metal is required, the sheet metal is placed in the bending mold at the desired bending position. The first electric cylinder 7 drives the connecting frame 6 to move. When the connecting frame 6 moves, it drives the two sliding tubes 14 to move on the two sliding rods 5, thereby moving the two support plates 2 and the two clamping plates 3 to adapt to the fixing of sheets of different lengths. Then, the second electric cylinder 13 drives the push rod 12 to move. When the push rod 12 moves, it drives the clamping plates 3 to move, thereby clamping and fixing the sheet metal between the two clamping plates 3. After the two clamping plates 3 clamp and fix the two sides of the sheet metal, when the sheet metal swings during the bending process, it will drive the slide plate 9 to slide in the guide frame 8 and slide in the sliding hole through the arc rod 10. With the support of the support spring 11, the clamping plates 3 move with the direction of the sheet metal swing, thereby increasing the stability of the sheet metal when it swings under bending force and effectively preventing the sheet metal from deviating.
