[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] The present embodiment provides a chain-type punch press safety door with a counterweight, which is installed at the operating opening position of the punch press body 100. The chain-type punch press safety door uses a driving motor 41 to drive the punch press safety door, and does not need to be driven by a cylinder. It can effectively save the installation space of the punch press safety door and meet the installation requirements of the punch press safety door.

[0028] Combination Figures 1 to 4 As shown, the punch press safety door of this embodiment includes a door body 10, a transmission chain 20 and a counterweight block 30. The door body 10 can cover the operating opening position of the punch press body 100, the transmission chain 20 can drive the door body 10 to open or close the door body 10, and the counterweight block 30 can counterweight the door body 10 to make the movement of the door body 10 smoother, thereby enhancing the stability of the door body 10 during movement.

[0029] In this embodiment, the door body 10 moves along the height direction of the operating opening position of the punch body 100 to open or close the operating opening position of the punch body 100. The door body 10 does not need to be driven by a cylinder, which effectively saves the installation space of the cylinder components and meets the installation requirements of the door body 10.

[0030] See also Figure 2 There are two groups of transmission chains 20 and they are located at both ends of the door body 10 to transmit the power to the door body 10 . The counterweight block 30 is installed on the transmission chain 20 . When the transmission chain 20 is transmitting, the counterweight block 30 and the door body 10 move in opposite directions, so that the counterweight block 30 counterweights the door body 10 .

[0031] In this embodiment, the door body 10 is located at one end of the transmission chain 20, and the counterweight block 30 is located at the other end of the transmission chain 20. When the door body 10 moves, the counterweight block 30 can counterweight the door body 10 to enhance the stability of the door body 10 during transmission.

[0032] Specifically, in this embodiment, the mass of the counterweight block 30 is half of the door body 10 , and the mass of the two counterweight blocks 30 is equal to the mass of the door body 10 , thereby achieving complete counterweighting of the door body 10 .

[0033] Combination Figure 2 and Figure 3As shown, a driving part 40 is provided on the punch body 100, and the driving part 40 drives the transmission chain 20. The driving part 40 includes a driving motor 41 and a rotating shaft 42 located at the driving end of the driving motor 41. The transmission chain 20 is connected to the rotating shaft 42 through a sprocket 50. The sprocket 50 of this embodiment is installed on the rotating shaft 42 and rotates synchronously with the rotating shaft 42. There are two sprockets 50 and they are located at both ends of the rotating shaft 42, which cooperate with the two groups of transmission chains 20 respectively to drive the two groups of transmission chains 20.

[0034] See also Figure 2 and Figure 4 A guide rod 60 is provided on the punch body 100, and the door body 10 is connected to the guide rod 60 through a slider 70. There are two groups of guide rods 60 and they are located at both ends of the door body 10 to guide the movement of the door body 10. When the door body 10 moves, it is connected to the guide rod 60 through the slider 70. Under the cooperation of the guide rod 60 and the slider 70, the door body 10 is guided to move, thereby improving the movement stability of the door body 10.

[0035] In this embodiment, the slider 70 is fixedly connected to the transmission chain 20 through the connecting block 80. When the transmission chain 20 is driven, the slider 70 is driven synchronously. During the movement, the slider 70 pulls the door body 10 to realize the opening and closing of the door body 10.

[0036] In actual use of the punch press safety door of this embodiment, the transmission chain 20 will drive the door body 10 for transmission, and the transmission chain 20 is driven by the driving motor 41 and the rotating shaft 42. Compared with the traditional cylinder installation drive, it can effectively save space and meet the installation requirements of the door body 10. The counterweight block 30 is arranged on the transmission chain 20, which can counterweight the door body 10 and make the transmission of the door body 10 more stable. At the same time, the driving motor 41 can drive the door body 10 more easily through the transmission chain 20, thereby enhancing the stability of the door body 10 during transmission.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
