[0020] The middle part of top plate 4 is fixedly provided with hydraulic cylinder 13, and the lower end of hydraulic cylinder 13 is fixedly connected with upper die 6. The extension and shortening of hydraulic cylinder 13 can drive upper die 6 to move up and down for stamping work. Of course, the hydraulic cylinder 13 can also be replaced by a gas cylinder as needed, and the replacement can be performed under the condition that the stamping pressure is not very large.

[0021] The upper end of bottom plate 1 is fixedly provided with hydraulic control box 14, and the extension and shortening work of hydraulic cylinder 13 can be controlled through hydraulic control box 14.

[0022] The grating signal transmitting end 11, the grating signal receiving end 12 and the hydraulic control box 14 are electrically connected. When the optical signal of the grating signal transmitting end 11 is blocked, causing part of the optical signal received by the grating signal receiving end 12 to be lost, an electrical signal can be sent to the hydraulic control box 14. At this time, the hydraulic control box 14 can control the hydraulic cylinder 13 to not extend and push the upper die 6 to move down.

[0023] The connecting shaft 7 and the rotation axis 9 are both damping shafts. The connecting shaft 7 and the rotation axis 9 of the damping shaft can ensure that self-rotation does not easily occur without human operation, so that the grating signal transmitting end 11 and the grating signal receiving end 12 cannot be moved.

[0024] The four protection mechanisms are symmetrically arranged at the four corners of the upper end surface of the base plate 1, so that an isolated space can be formed by the four protection mechanisms, when the hands of the operator pass through the light barrier signal transmitting end 11 and the light barrier signal receiving end 12 and enter the space between the lower mold 2 and the upper mold 6, the light signal receiving of the light barrier signal receiving end 12 is lost, and an electric signal can be sent to the hydraulic control box 14, so that the hydraulic control box 14 can control the hydraulic cylinder 13 to not extend to push the upper mold 6 to move downward.

[0025] The working principle is that when the device is used, an isolated space can be formed on the upper end of the base plate 1 by the four protection mechanisms, when the hands of the operator pass through the light barrier signal transmitting end 11 and the light barrier signal receiving end 12 and enter the space between the lower mold 2 and the upper mold 6, the light signal receiving of the light barrier signal receiving end 12 is lost, and an electric signal can be sent to the hydraulic control box 14, so that the hydraulic control box 14 can control the hydraulic cylinder 13 to not extend to push the upper mold 6 to move downward, so that the device cannot be punched when any structure blocks the light barrier to transmit the model, thereby effectively preventing any physical object from being placed on the upper end of the base plate 1 during punching, thereby significantly improving the safety of the device during use.

[0026] And when the device is used, the rotating arm 8 and the rotating shaft 9 are rotated, so that the rotating arm 8 drives the light barrier signal transmitting end 11 and the light barrier signal receiving end 12 to move to different positions, and then the rotating shaft 9 ensures that the adjacent light barrier signal transmitting end 11 and the light barrier signal receiving end 12 are aligned, so that the size of the isolated space formed by the light barrier signal transmitting end 11 and the light barrier signal receiving end 12 can be changed, so that the device can adapt to various use cases.
