Detailed Description
The present invention will be described in further detail with reference to examples.
The invention discloses a safety protection device of a cold-rolling recoiling flanging machine, which comprises a wall I13 and a wall II 14 which are positioned at a passage 9 of an underground stair of the flanging machine, a protective door 3 arranged on the wall I13 through a door shaft 12, an elastic structure arranged on the wall I13 and in contact fit with the protective door 3, a door pin 2 arranged on the wall II 14 and used for opening and closing the protective door 3, a control interlocking switch 1 arranged on the wall II 14 and corresponding to a switch of the protective door 3, and a safety alarm device connected with the control interlocking switch 1, wherein the control interlocking switch 1 is also connected with the flanging machine 8;
the elastic structure comprises an L-shaped steel plate II 7 arranged on a wall I13, a plurality of springs 5 arranged on the L-shaped steel plate II 7 in parallel through fastening devices 6, and a steel plate I4 arranged at the other end of each spring 5, wherein the steel plate I4 is in contact fit with the protective door 3;
the safety alarm device comprises an alarm lamp control cabinet 11 connected with the control interlock switch 1 and an alarm lamp 10 connected with the alarm lamp control cabinet 11. The alarm lamp control cabinet 11 is installed in 8 pit rear wall departments of beading machine, and the alarm lamp 10 is installed subaerial, and the alarm lamp 10 is the LED alarm lamp.
The spring 5 comprises a spring body 51 and a limiting structure, wherein the spring body 51 comprises at least two coil layers 52, and each coil layer 52 is provided with a through hole 53 which is vertical to the adjacent coil layer 52 and has the hole center on the same straight line; the limiting structure comprises a rope 55 passing through the through holes 53 and blocking bodies 56 fixed on the rope 55 between the adjacent spiral ring layers 52, the length between the adjacent blocking bodies 56 is not more than the maximum effective elastic length which can be reached by the adjacent spiral ring layers 52, and the aperture of each through hole 53 is less than the maximum effective diameter of each blocking body 56; a limiting groove 57 is fixedly arranged above each ring layer 52, the bottom of the limiting groove 57 is in a cambered surface structure, the limiting groove 57 is in a V-shaped structure with an upward opening, and the upper and lower adjacent limiting grooves are staggered 57.
The fastening device 6 is a bolt, and the number of the bolts is 2-6, such as 4, which are arranged in parallel up and down. The control interlocking switch 1 is a proximity switch, so that the induction is sensitive and the response is rapid.
The specific working principle of the invention is as follows: when the protective door 3 is opened, the curling machine stops working by controlling the interlocking switch 1, the alarm lamp 10 sounds in a flashing manner, and the operation of the ground control panel of the curling machine is ineffective; the protective door 3 is closed, the curling machine is automatically started to work, the alarm lamp 10 is in signal off-stop, and the ground control panel of the curling machine is effectively operated.
