Detailed Description
The attached drawing is a specific embodiment of the utility model discloses a disconnected protection device of taking of cutting off type cold rolled sheet. The embodiment comprises a multi-roller mill 5 arranged on a rack, wherein the multi-roller mill 5 is a reversible cold rolling mill set, the left side of the multi-roller mill 5 is sequentially provided with a left control shear 3, a left thickness gauge 13, a left steering roll 2 and a left coiling machine 1, and the left control shear 3 is close to the multi-roller mill 5; the structure of the right side of the multi-roller mill 5 is symmetrical to the structure of the left side of the multi-roller mill 5; namely, the whole cold-rolled sheet production line comprises a left coiling machine 1, a left steering roll 2, a left thickness gauge 13, a left control shear 3, a multi-roll mill 5, a right control shear 6, a right thickness gauge 14, a right steering roll 8 and a right coiling machine 9 which are sequentially arranged on a rack. The left control scissors 3 comprise upper scissors blades 7 and lower scissors blades 4 which are symmetrically arranged on two sides of the thin plate production line, the upper scissors blades 7 are connected with a driving mechanism 10, the lower scissors blades are fixed on the rack, and the upper scissors blades fall onto the lower scissors blades when working and are overlapped with the lower scissors blades; the driving mechanism 10 is driven by air or hydraulic pressure, the air or hydraulic pressure comprises one or more air cylinders or hydraulic cylinders connected with the left control scissors 3, as shown in fig. 2, a first air cylinder 15 and a second air cylinder 12 are respectively arranged on the scissors upper edge 7 of the left control scissors 3, and are used for driving the scissors upper edge 7 to fall down to cut off the thin plate when the machine fails; the driving mechanism 10 is respectively connected with a PLC controller and an emergency stop button circuit.
The control electric signal of scissors upper blade 7 whereabouts is connected through the PLC controller all the way, namely scissors upper blade is connected with actuating mechanism, actuating mechanism connection control electric signal, the control electric signal is connected with the PLC controller, establish communication connection between PLC controller and multi-roll mill converter, the converter of left and right coiling machine, the encoder and the rolling system of testing the speed in the rolling process of multi-roll mill, can judge the emergence condition of strip breakage accident through speed difference, tension difference and rolling poor difference, scissors upper blade 7 falls rapidly when detecting the fault signal, cuts the sheet metal. The other path of the control signal for the falling of the upper edge 7 of the scissors is connected with emergency stop buttons at all positions of the multi-roll mill, and when the machine fails, a worker can press the emergency stop buttons to realize the falling of the upper edge of the scissors and cut off the thin plate. When the fault processing is finished, the upper edge of the scissors is controlled to rise, and the machine is recovered to normal operation. The two control modes can realize the cutting of the thin plate, and the condition that the machine fails to process when a worker is not on the spot is avoided.
In the embodiment, the multi-roll mill 5 is a reversible multi-roll mill, and the left control scissors 3 and the right control scissors 6 are symmetrically arranged on two sides of the multi-roll mill 5, so that bidirectional rolling can be realized, and when a sheet is rolled from left to right, only the left control scissors 3 need to be controlled when a fault occurs; when the thin plate is rolled from right to left, only the right control scissors 6 need to be controlled when a fault occurs.
The working principle is as follows: in the process of cold rolling the sheet, the sheet moves backwards from the left coiler 1, is conveyed to the left steering roll 2, then is measured for thickness by the left thickness gauge 13, and then is conveyed into a roll gap of the multi-roll mill 5, the multi-roll mill 5 continuously conveys backwards after rolling the sheet, passes through the right thickness gauge 14, the right steering roll 8 and the right coiler, when the sheet in the left coiler 1 is conveyed to the right coiler 9 after being rolled, the direction of the sheet working line is adjusted, so that the sheet is conveyed to the left coiler 1 from the right coiler 9 after the series of operations, and is rolled again. In all the processes, when the raw material is in defect, misoperation, equipment or electrical fault, the PLC sends fault information to the control electric signal, the control electric signal controls the compressed air to push the pistons of the first air cylinder 15 and the second air cylinder 12 to move simultaneously, so that the upper edge 7 of the scissors falls to be overlapped with the lower edge 4 of the scissors, and finally, the cold-rolled sheet is cut off, and the protection of the multi-roll mill 5 is realized.
The above embodiments of the present invention are merely exemplary, not exclusive, and all changes within the scope of the present invention or equivalent thereof are encompassed by the present invention.
