[0003] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench, and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressing plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil, and a cover plate. The coil is placed in the recess of the housing, and the cover plate covers the top of the recess. When in use, an electric current is applied to the coil through a wire. After the electric current is applied, an attractive force is generated on the pressing plate, thereby realizing the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made according to various workpiece requirements, and workpieces with side walls can be processed, and the operation is also very simple.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-4 to further elaborate on the present application: Embodiment

[0033] The embodiment discloses a telescopic material-supporting mechanism of a bending machine, which is mainly used to provide stable material-supporting for workpieces of different lengths during the working process of the bending machine. Refer to Figure 1 , this mechanism includes a frame 1, and two sliding frames 2 that can slide along the length direction of the frame 1 are slidably connected to the frame 1. A set of material-supporting components 3 are provided on each sliding frame 2, and the two material-supporting components 3 have the same structure. Only one set of the material-supporting components 3 is taken as an example here.

[0034] Specifically, refer to Figure 2 and Figure 3, the material supporting component 3 includes a cylinder 31 fixed on the sliding frame 2. The cylinder 31 serves as a driving member. The cylinder 31 is horizontally placed, and a connecting plate 32 is fixedly connected to the end of its piston rod. A material supporting brush 33 is bolted to the end of the connecting plate 32, and the material supporting brush 33 is horizontally arranged. This connection method not only facilitates disassembly, assembly, and maintenance, but also ensures that the material supporting brush 33 slides smoothly with the telescopic movement of the piston rod of the cylinder 31, thereby realizing the telescopic function of the material supporting component 3, effectively supporting workpieces of different lengths, and reducing the sagging of the workpieces.

[0035] Referring to Figure 4 , wherein, a slider 34 is fixedly connected to the bottom of the material supporting brush 33, a guide rail is fixedly connected to the top of the sliding frame 2, a chute 36 is formed in the guide rail, and the slider 34 is slidably connected in the chute 36; when the cylinder 31 pushes the material supporting brush 33 to slide, the slider 34 slides in the chute 36, playing a guiding and limiting role for the material supporting brush 33, making the material supporting brush 33 more stable during the sliding process.

[0036] The implementation principle of Embodiment 1 is as follows: when the workpiece enters the bending machine for processing, the sliding frame 2 is adjusted to an appropriate position according to the length of the workpiece. Subsequently, the piston rod of the cylinder 31 extends, driving the material supporting brush 33 to expand and contract to an appropriate length, closely fitting the bottom of the workpiece, providing a stable lifting force for the workpiece, reducing the sagging phenomenon of the workpiece caused by gravity, and ensuring the processing accuracy of the workpiece. Embodiment

[0037] On the basis of Embodiment 1, this embodiment further improves the protection measures for the cylinder 31. Referring to Figure 2 and Figure 3 , specifically, a baffle 37 is provided on the top of the cylinder 31. The baffle 37 can effectively protect the cylinder 31, preventing foreign objects or dust from entering the inside of the cylinder 31 and affecting its normal operation. At the same time, the baffle 37 can also play a certain buffering role, avoiding the cylinder 31 being damaged by direct impact during use.

[0038] The implementation principle of Embodiment 2 is as follows: by adding the baffle 37, an additional protective layer is provided for the cylinder 31. During daily use, the baffle 37 can effectively block the adverse effects of the external environment on the cylinder 31, ensuring that the cylinder 31 can operate in a stable and safe environment, thereby extending its service life. Embodiment

[0039] On the basis of Embodiment 1, referring to Figure 3 and Figure 4, in this embodiment, a set of special-shaped finger blocking components 4 is added to the top of the sliding rack 2, which is mainly used to limit the end of the workpiece during the material supporting process. Specifically, the special-shaped finger blocking component 4 includes a slidable finger blocking plate 41. A sliding block is fixedly connected to the bottom of the finger blocking plate 41. A guide rail 43 is fixedly connected to the top of the sliding rack 2, and the sliding block is slidably connected to the guide rail 43. A driving motor 44 is fixedly connected to the top of the sliding rack 2. A lead screw 45 is fixedly connected to the end of the output shaft of the driving motor 44. A connecting rod 46 is fixedly connected to the side wall of the finger blocking plate 41, and the connecting rod 46 is threadedly connected to the lead screw 45. When it is necessary to adjust the position of the finger blocking plate 41, the driving motor 44 is started to drive the lead screw 45 to rotate, thereby driving the finger blocking plate 41 to slide precisely along the lead screw 45.

[0040] Among them, a plurality of stepped grooves 431 are formed at the end of the finger blocking plate 41. Each stepped groove 431 can be used to limit plates of different thicknesses, and a special-shaped groove is arranged in each stepped groove 431 for limiting the end of a special-shaped workpiece.

[0041] The implementation principle of Embodiment 3 is as follows: Through the precise control of the power component, the finger blocking plate 41 can quickly and accurately move to the predetermined position to effectively limit the end of the workpiece. This design not only improves the stability of the workpiece during the processing process but also ensures the processing accuracy and working efficiency of the workpiece. At the same time, due to the adoption of an automated control method, the labor intensity of the operator is also greatly reduced. Embodiment

[0042] This embodiment discloses a bending machine equipped with a telescopic material supporting mechanism. In addition to including all the technical features of the foregoing embodiments, further optimized designs are carried out on the frame 1, the sliding rack 2, and other related components. For example, the frame 1 is made of high-strength and lightweight aluminum alloy material to improve the stability and rigidity of the whole machine; the sliding rack 2 adopts a sliding mechanism composed of a high-precision linear guide rail 43 and a ball screw 45 to ensure the accuracy and smoothness of the sliding rack 2 during the sliding process.

[0043] The implementation principle of Embodiment 4 is as follows: By comprehensively applying the technical advantages of the foregoing embodiments and combining modern mechanical design and manufacturing processes, a high-performance and high-efficiency bending machine is created. The machine not only has a powerful workpiece support and limiting function but also has excellent processing accuracy and working efficiency performance. At the same time, its stable frame 1 structure and precise sliding rack 2 sliding mechanism also provide a strong guarantee for the stability and durability of the overall equipment.

[0044] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. In the actual application process, the above embodiments can be flexibly combined or adjusted according to specific needs. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered by the protection scope of the present application.
