[0002] A bending machine is a device widely used in the metal processing industry, mainly used for precisely and efficiently bending metal sheets. When processing sheets, generally a bending machine is needed to bend the sheets according to processing requirements. Bending machines can be divided into manual bending machines, hydraulic bending machines and numerical control bending machines. The bending machine realizes the bending and forming of the sheets by moving the upper die and combining the shape of the lower die.

[0003] In the actual use process of the existing bending machines, when moving the sheet to the bending position, the sheet is generally transported by manual holding. When transporting the sheet, it is easily affected by human factors, causing the sheet to shift and tilt, which affects the bending effect.

[0004] The existing patent (publication number: CN218475817U) discloses a bending machine, which includes a base. A pressing die is installed at the upper end of the base. A lifting mechanism is arranged above the pressing die at the upper end of the base. A bearing table is connected to the side of the base through the lifting mechanism. A bending knife is installed at the lower end of the bearing table. A material placing table is fixed to the side of the base. It limits the sheet through a fixing mechanism. By moving the L-shaped block so that its inner side contacts both ends of the sheet, both sides of the sheet are limited, and the upper end of the sheet is limited by a fixing component, reducing the occurrence of the situation that the sheet shifts during bending and affects the bending effect.

[0005] In view of the above problems, although the solution given by the existing patent has the function of limiting the sheet through a fixing mechanism to reduce the shift of the sheet during bending, it is not convenient to quickly disassemble and assemble the bending die, reducing the replacement efficiency of the bending die and increasing the workload of the staff. Summary of the Invention

[0006] The purpose of the utility model is to provide a bending machine with a quick die removal structure, which can screw down the fixing bolts, separate the fixing holes on the fixing bolts and the fixing block, and then release the fixation of the fixing block.

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a bending machine with a mold quick-release structure, including a bending machine frame 1, a reinforcing plate 2 is horizontally fixed inside the bending machine frame 1, a quick-release mechanism for quick release of the mold is provided on the inner wall of the bending machine frame 1, and a bending mechanism for bending the workpiece is fixed at the upper end of the bending machine frame 1;

[0028] The quick-release mechanism includes mounting grooves 3. There are two mounting grooves 3, both of which are opened on the inner wall of the bending machine frame 1. Fixed blocks 31 are slidably connected inside both of the two mounting grooves 3. A lower mold 32 is fixed to the side wall of the fixed block 31. A fixing hole 33 is opened on one side of the fixed block 31. A fixing bolt 34 inserted and connected to the fixing hole 33 is installed on the outer wall of the bending machine frame 1. The bending mechanism includes a mounting member 4. The mounting member 4 is fixed to the upper end of the bending machine frame 1. A hydraulic cylinder 41 is fixed inside the mounting member 4 by bolts. A limiting plate 42 is fixed to the telescopic end of the hydraulic cylinder 41. A movable plate 43 is fixed to the lower end of the limiting plate 42. A fixing member 44 is fixed to one side of the lower end of the movable plate 43. An upper mold 45 is fixed to one side of the fixing member 44. A clamping mechanism for clamping the workpiece is fixed to the other side of the lower end of the movable plate 43.

[0029] By adopting the above technical solution, before using the bending machine with the mold quick-release structure, first place the bending machine frame 1 in a suitable position. During use, input the workpiece from the feeding end of the bending machine. When the workpiece moves above the lower mold 32, the hydraulic cylinder 41 arranged inside the mounting member 4 is started, driving the limiting plate 42 to move vertically, and then driving the movable plate 43 to move, so that the fixing member 44 drives the upper mold 45 to move towards the lower mold 32, thereby bending the workpiece. Through the reinforcing plate 2 arranged inside the bending machine frame 1, the strength of the bending machine can be enhanced. When it is necessary to disassemble and replace the lower mold 32, unscrew the fixing bolt 34, so that the fixing bolt 34 and the fixing hole 33 on the fixed block 31 are separated, thereby releasing the fixation of the fixed block 31. With the cooperation of the mounting groove 3, the lower mold 32 can be pulled horizontally, which is convenient for disassembling the lower mold 32 and is easy to use.

[0030] Specifically, as Figures 1 - 4 shown, the clamping mechanism includes a mounting plate 5. The mounting plate 5 is fixed to the other side of the lower end of the movable plate 43. A mounting tube 51 is fixed to the lower surface of the mounting plate 5. A spring 52 is installed inside the mounting tube 51. The lower end of the spring 52 abuts against a movable block 53. A movable rod 54 slidably connected to the mounting tube 51 is fixed to the lower end of the movable block 53. A clamping plate 55 is fixed to the lower end of the movable rod 54.

[0031] By adopting the above technical solution, when the movable plate 43 moves, it will drive the mounting plate 5 to move. Through the spring 52 arranged inside the mounting tube 51, when the clamping plate 55 first contacts the upper surface of the workpiece and then the movable plate 43 continues to move, with the cooperation of the movable rod 54, it will push the movable block 53 to move. At this time, the spring 52 will be compressed, causing the spring 52 to generate tension and extruding the movable rod 54, so that the clamping plate 55 clamps the workpiece tightly, thereby effectively reducing the situation of the workpiece shifting during processing.

[0032] Working principle: The workpiece is input from the feeding end of the bending machine. When the workpiece moves above the lower die 32, the hydraulic cylinder 41 arranged in the mounting member 4 drives the limiting plate 42 to move vertically, and then drives the movable plate 43 to move, so that the fixing member 44 drives the upper die 45 to move towards the lower die 32, thereby bending the workpiece. When the movable plate 43 moves, it will drive the mounting plate 5 to move. Through the spring 52 arranged in the mounting pipe 51, when the clamping plate 55 first contacts the upper surface of the workpiece, the movable plate 43 continues to move. With the cooperation of the movable rod 54, it will push the movable block 53 to move. At this time, it will push the spring 52 to be compressed and squeeze the movable rod 54, so that the clamping plate 55 tightly clamps the workpiece, thereby effectively reducing the situation of the workpiece shifting during processing. Through the reinforcing plate 2 arranged in the bending machine frame 1, the strength of the bending machine can be enhanced. When it is necessary to disassemble and replace the lower die 32, unscrew the fixing bolt 34, so that the fixing bolt 34 is separated from the fixing hole 33 on the fixing block 31, thereby releasing the fixing of the fixing block 31, and horizontally pulling the lower die 32 is convenient for disassembling the lower die 32.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
