Description

Technical Field

[0001] This application relates to the technical field of bending machines, and specifically to a bending machine. Background Art

[0002] A bending machine is a general-purpose equipment for bending and forming metal sheet materials. It can fold workpieces of various shapes with simple dies. The upper module is equipped with a compensation mechanism to ensure high bending working accuracy. Users only need to equip various different dies to bend the sheet material into workpieces of various different shapes. It can also perform punching and shearing processes. The bending machine is widely applicable to the bending and forming processing of metal sheet materials in industries such as automobiles, machinery, shipbuilding, electrical appliances, light industry, and decoration.

[0003] The existing patent (publication number: CN211275989U) discloses a bending mechanism of a bending machine. Aiming at the problem that when installing a die on the existing bending machine, it is necessary to manually rotate the screw to clamp the die, which is a cumbersome process and time-consuming and laborious. The following solution is now proposed. It includes an L-shaped column. A pressure-bearing workbench is fixedly arranged above the L-shaped column. A buffer pad is fixedly arranged at the bottom of the pressure-bearing workbench. And two first chutes are opened on the pressure-bearing workbench. A clamping rod is slidably arranged in each of the two first chutes. A die is placed between the clamping rods. The bottom of the clamping rod is fixedly connected with a nut.

[0004] It is pointed out in the above comparative document that when the telescopic rod descends, the L-shaped rod will rotate the cross bar, and when the first gear on the cross bar rotates, it will drive the screw to rotate. The nuts arranged at both ends of the screw will drive the clamping rods to approach each other. By matching the sliding block with the inclined groove, the clamping rod is lifted to clamp the die. The operation is simple and fast. However, when this device is bent, there is no limiting device, and the bending position cannot be determined during use, resulting in insufficient bending accuracy and inability to meet the production requirements of high-precision workpieces. During mass production, there may be dimensional differences in the workpieces after bending, resulting in unstable product quality and affecting the service performance of the final product.

A bending plate 10 is fixedly connected to the upper end of the workbench 1.

[0032] Please refer to Figure 1 、 Figure 3 andFigure 4 At one end of the upper end of the workbench 1 away from the backing plate 2, a support frame 11 is fixedly connected. Inside the upper end of the support frame 11, three first mounting holes 12 arranged in a linear array are opened. Inside each of the three first mounting holes 12, a hydraulic rod 13 is fixedly connected. The hydraulic rod 13 can provide stable and controllable bending force. Hydraulic drive has better load capacity and stability, which can ensure that the workpiece receives uniform and constant pressure during the bending process, thereby improving the processing accuracy and workpiece quality. Through the three hydraulic rods 13 arranged in a linear array, multi-point support and uniform force application can be provided for the bending operation. This design can ensure that the workpiece receives uniformly distributed pressure during the bending process, reducing the risk of workpiece deformation or damage.

[0034] In this embodiment, for the bending machine, through the arrangement of the threaded rod 8 and the limiting plate 9, the operator can easily adjust the position of the limiting plate 9 to adapt to workpieces of different sizes and bending requirements, ensuring the accuracy and consistency of the bending operation. The combined use of the chute 4 and the baffle 5 on one side of the placement plate 3 can conveniently fix workpieces of different lengths, prevent the workpiece from shifting or sliding during the bending process, thereby improving the safety of the operation and also contributing to improving the bending accuracy.

[0035] It should be noted that one end of the workpiece to be bent is abutted against one side of the limiting plate 9, and the baffle 5 is used to resist the other end of the workpiece.

[0036] The working principle of the above embodiment is as follows:

[0037] The operator places the workpiece on the placement plate 3, making one end of the workpiece to be bent abut against one side of the limiting plate 9. According to the length of the workpiece, by sliding the baffle 5 in the chute 4 until the baffle 5 closely abuts against the other end of the workpiece, thus fixing the position of the workpiece. According to the size and bending requirements of the workpiece, the operator can rotate the threaded rod 8. Through the threaded connection between the threaded rod 8 and the fixed block 6, the limiting plate 9 is driven to move to a suitable position to ensure that the workpiece does not shift during the bending process. The fixing bolt 20 is passed through the second mounting hole 19 of the mounting seat 16 and screwed into the second threaded hole 18 of the fixed seat 15 to ensure the stable and reliable connection between the mounting seat 16 and the fixed seat 15. Then the bending knife 17 is installed. The operator steps on the foot switch 22 to start the hydraulic rod 13. The three hydraulic rods 13 work together, and the moving plate 14 is pushed downward through the telescopic end. The moving plate 14 drives the fixed seat 15, the mounting seat 16 and the bending knife 17 to move downward until the bending knife 17 contacts the workpiece and starts to bend. The bending plate 10 corresponds to the bending knife 17 to ensure that the workpiece is accurately placed within the working area of the bending knife 17 during the bending process, realizing a high-precision bending operation.
