[0026] The transmission assembly 3 includes a fixed plate 301, an electric telescopic rod 302 and a transmission block 303.

[0027] In this embodiment: by setting the bending machine body 1, the protective cover 2, the transmission component 3, the sensor control component 4 and the induction block 5, when in use, after the workpiece is loaded, the transmission component 3 is started, and the protective cover 2 is driven to move by the transmission component 3, and the induction block 5 is driven to move while the protective cover 2 moves, so that the protective cover 2 moves to the protection area on the front side between the bending knife and the lower die of the bending machine body 1. When the protective cover 2 moves into place, the induction block 5 will be in the same plane as the sensor control component 4. At this time, the sensor control component 4 will start the bending machine body 1 to perform bending work. When the protective cover 2 does not reach the protection area, the sensor control component 4 cannot get a signal, and the bending machine body 1 is in a power-off state, and the bending machine body 1 will not perform bending work, so that the protective cover 2 is used to form a protective barrier on the front side between the bending knife and the lower die of the bending machine body 1, so that when the bending machine body 1 is working, the staff cannot put their hands between the bending knife and the lower die of the bending machine body 1, thereby improving the effect of safe operation.

The bottom of the left side of the support frame 401 is fixedly connected to the bending machine body 1, the right side of the sensor 402 is fixedly connected to the top of the left side of the support frame 401, and the left side of the controller 403 is fixedly connected to the bending machine body 1.

[0029] In this embodiment: by setting up a support frame 401, the sensor 402 can be supported and positioned. By setting up the sensor 402, a signal can be sent to the controller 403 when the protective cover 2 and the induction block 5 reach the protective position. By setting up the controller 403, the bending machine body 1 can be started to work when the signal is received.

[0030] As a technical optimization solution of the utility model, both sides of the bending machine body 1 are fixedly connected with limiting slide rails 6 used in conjunction with the protective cover 2, and the side of the protective cover 2 close to the inner wall of the limiting slide rail 6 is slidably connected to the inner wall of the limiting slide rail 6.

[0031] In this embodiment, by providing a limiting slide rail 6, the protective cover 2 can be limited so that the protective cover 2 will not shake when moving.

[0032] As a technical optimization solution of the present invention, an observation port 7 is provided on the front side of the protective cover 2 , and a transparent plate 8 is fixedly connected to the inner wall of the observation port 7 .

[0033] In this embodiment, by providing the observation port 7 and the transparent plate 8 , the staff can conveniently observe the working status of the bending machine body 1 .

[0034] As a technical optimization solution of the utility model, a control panel body 9 is arranged on the right side of the bending machine body 1, and a protective shell 10 is connected to the front side of the control panel body 9 through a rotating shaft.

[0035] In this embodiment, the protective shell 10 is provided to protect the control panel body 9 so that the control panel body 9 can reduce the amount of dust that adheres to the control panel body 9 . The dust will reduce the touch screen sensitivity of the control panel body 9 .

[0036] As a technical optimization solution of the utility model, a first magnet 11 is fixedly connected to the right side of the protective shell 10, and a second magnet 12 is fixedly connected to the front side of the right side of the control panel body 9. The opposite sides of the first magnet 11 and the second magnet 12 are mutually attractive surfaces.

[0037] In this embodiment, by providing the first magnet 11 and the second magnet 12 , the position of the protective shell 10 can be simply fixed by the attraction between the magnets.

[0038] As a technical optimization solution of the utility model, a reinforcing rib 13 is fixedly connected to the front side of the top of the fixing plate 301 , and the side of the reinforcing rib 13 close to the bending machine body 1 is fixedly connected to the bending machine body 1 .

[0039] In this embodiment, by providing the reinforcing ribs 13 , the support stability of the fixing plate 301 on the electric telescopic rod 302 can be increased.

[0040] Working principle: first, after the workpiece is loaded, the electric telescopic rod 302 is started, and the output end of the electric telescopic rod 302 drives the transmission block 303 to move, and the transmission block 303 drives the protective cover 2 to move. When the protective cover 2 moves, the sensing block 5 is driven to move, so that the protective cover 2 moves to the protection area on the front side between the bending knife and the lower die of the bending machine body 1. When the protective cover 2 moves into place, the sensing block 5 will be in the same plane as the sensor 402. At this time, the sensor 402 sends a signal to the controller 403, and the controller 403 receives the signal to start the bending machine body 1 to perform the bending work. When the protective cover 2 does not reach the protection area, the sensor 402 cannot be sensed, and the controller 403 does not receive the signal, then the bending machine body 1 is in a power-off state, and the bending machine body 1 will not perform the bending work, thereby forming a protective barrier on the front side between the bending knife and the lower die of the bending machine body 1 through the protective cover 2, so that when the bending machine body 1 is working, the staff cannot put their hands between the bending knife and the lower die of the bending machine body 1, thereby improving the effect of safe operation.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
