Detailed Description
The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 2, an embodiment of the present invention provides a plug-in safety interlock device for forging machinery, which includes a rotating rod base 1, a rotating rod 3 rotatably installed in the rotating rod base 1, a coupling sleeve 6 sleeved on the rotating rod 3, a screw 4 fixed on the rotating rod 3, a spring 5 disposed inside the coupling sleeve 6, a proximity switch base 8 slidably connected to the coupling sleeve 6, and a proximity switch 7 disposed inside the proximity switch base 8, wherein the rotating rod 3 is rotatably connected to the rotating rod base 1 through a rotating pin 2, an outer wall of one end of the rotating rod 3 away from the rotating rod base 1 is slidably connected to an inner wall of the coupling sleeve 6, a fixing plate 6-1 is disposed on an inner wall of the coupling sleeve 6, a screw of the screw 4 passes through the fixing plate 6-1 and is fixed at one end of the rotating rod 3 away from the rotating rod base 1, the spring 5 is disposed between one end of the rotating rod 3 away from the rotating rod base 1 and the fixing plate 6-1, the proximity switch seat 8 is connected with the combination sleeve 6 in a sliding mode, a proximity switch 7 is fixed to one end, close to the combination sleeve 6, of the proximity switch seat 8, and the proximity switch 7 is electrically connected with the forging and pressing mechanical controller.
Preferably, the outer wall of the coupling sleeve 6 is provided with anti-slip lines. It is advantageous to increase the frictional force and drag the coupling sleeve 6.
Preferably, both ends of the rotation pin 2 are provided with fastening nuts. Facilitating the fixing of the swivelling levers 3.
Preferably, the outer wall of the end of the coupling sleeve 6 away from the rotating rod seat 1 is provided with a damping rubber sleeve. Which is advantageous for protecting the coupling sleeve 6.
The working process is as follows: all can install the ladder 9 that has the protective cage on the forging and pressing machinery, remove a horizontal pole of ladder 9, fix the rotating rod seat 1 and proximity switch seat 8 respectively on the position that is used for placing former horizontal pole of two montants, when forging and pressing machinery operation, will dwang 3 rotates clockwise along rotating pin 2 and is blocked as to combining cover 6 by next horizontal pole, and dwang 3 keeps motionless under the action of gravity this moment.
