[0021] like Figs. 1 to 3 As shown, the protective structure assembly for the bending machine in this embodiment includes a bending machine body 1. A workbench 2 is arranged on the bending machine body 1. A lower die 3 is installed on the upper surface of the workbench 2. The lower die 3 is installed on the workbench 2. An upper die 4 is installed on the bending machine body 1 above the lower die 3. The upper die 4 is installed on the power unit of the bending machine body 1 and can move up and down. Both ends of the upper die 4 are detachably equipped with fixing mechanisms. The fixing mechanisms are used to install sensors 6 on the upper die 4. Sensors 6 are infrared sensors installed on both fixing mechanisms. 6. Since the human body has a certain temperature, it emits infrared rays of a certain wavelength. The infrared sensor 6 uses a pyroelectric element. When the temperature of the human body changes due to infrared radiation, the element loses its charge balance and releases charges. After detection and processing by the subsequent circuit, it can control the upper mold 4 to stop moving to avoid injury to the human body. An auxiliary pressing mechanism is installed at the front end of the bending machine body 1 in front of the workbench 2. The auxiliary pressing mechanism is used to assist in clamping the thin plate to be processed, eliminating the need for manual handling and avoiding scratches to the human body.

[0022] Specifically, the fixing mechanism comprises a fixing plate 501, a moving plate 502, a connecting plate 503, a screw rod 504, a knob 505, a moving rod 506, and a mounting plate 507. The fixing plate 501 is installed at one end of the rear side of the connecting plate 503. The moving plate 502 is slidingly installed on the surface of one end of the connecting plate 503 in front of the fixing plate 501. The screw rod 504 is installed at the front end of the moving plate 502 through a screw hole. The rear end of the screw rod 504 is rotationally connected with the fixing plate 501. The knob 505 is installed at the front end of the screw rod 504. The moving rod 506 is slidingly installed on the connecting plate 503. The moving rod 506 is L-shaped. The mounting plate 507 is installed at one end of the moving rod 506. The inductor 6 is installed on the mounting plate 507. The inductor 6 is located below the lower die 3 and has a certain distance from the lower die 3. The knob 505 is rotated to drive the screw rod 504 to rotate, and the screw rod 504 drives the moving plate 502 to move, so that the lower die 3 is fixed between the fixing plate 501 and the moving plate 502, thereby achieving the installation of the inductor 6. Meanwhile, the upper die 4 of various thicknesses can be used, and the applicability is good.

[0023] Further, a through hole 8 is arranged through the upper end of the connecting plate 503. The moving rod 506 is slidingly arranged in the through hole 8. A fixing bolt 9 is installed on the surface of the other end of the connecting plate 503 through a screw hole. One end of the fixing bolt 9 extends to the surface of the moving rod 506. The moving rod 506 is L-shaped. The distance between the inductor 6 and the lower end of the lower die 3 can be adjusted by the position of the moving rod 506, so that the protective distance of the inductor 6 can be adjusted.

[0024] Further, a guide plate 10 is installed on the surface of one end of the connecting plate 503 above and below the moving plate 502. The guide plate 10 can limit the rotation of the moving plate 502 when the moving plate 502 moves, thereby playing a guiding and limiting role.

The support rod 701 is installed on both sides of the front end of the bending machine body 1 in front of the workbench 2. The placing plate 702 is fixedly installed between the two support rods 701. The pressing plate 703 is slidingly installed between the two support rods 701 above the placing plate 702. The sheet to be processed is placed on the placing plate 702, and then the pressing plate 703 is moved downward to clamp the sheet between the placing plate 702 and the pressing plate 703, thereby achieving the function of auxiliary clamping without the need for workers to hold, avoiding scratches on the human body. There is a certain damping between the pressing plate 703 and the support rod 701.

[0026] Further, the upper end of the placing plate 702 and the upper end of the lower die 3 are on the same horizontal line, so that the sheet to be bent can be placed horizontally.

[0027] The use method of the embodiment is: before use, first rotate the rotating knob 505 to drive the screw rod 504 to rotate, the screw rod 504 drives the moving plate 502 to move, the lower mold 3 is located between the fixed plate 501 and the moving plate 502, the installation of the inductor 6 is realized, in use, the sheet to be processed is placed on the placing plate 702, then the pressing plate 703 is moved downward, the sheet is clamped between the placing plate 702 and the pressing plate 703, then the upper mold 4 is controlled to move downward, the sheet is bent, in the process, the two inductors 6 are inducted, when any inductor 6 senses that there is a human body limb below the lower mold 3, the inductor 6 controls the upper mold 4 to stop descending, the harm to the human body limb is avoided, the inductor 6 can only detect the human body limb, the sheet does not affect the downward movement of the upper mold 4, after the bending is completed, the pressing plate 703 is moved upward, the bent sheet is taken out.
