After unwinding, cutting, leveling and shaping, various specifications of fixed-length steel plates are obtained. They are widely used in industries such as stainless steel products, electrical appliances, vehicles and machinery manufacturing.

[0003] For the cutting and shaping of steel plates, traditional production lines mostly use a combination of single-function mechanical equipment. For example, the plates are first cut to length by a cutting machine or a flying shear, and then the flatness of the cut plates is corrected by a leveling machine. For waste materials in production, open waste chutes are generally used for collection.

[0044] The flying shear device 4 is used to cut the steel plate according to a predetermined length to obtain small steel blocks of the same length. The flying shear device 4 includes a flying shear machine, which is provided with an upper shear blade 41 and a lower shear blade 42 that are opposite to each other. The steel plate is sheared by the upper shear blade 41 and the lower shear blade 42. The upper shear blade 41 and the lower shear blade 42 are respectively installed on the upper crankshaft and the lower crankshaft, which are respectively connected to the two output shafts of the gear distribution box through two couplings. The gear distribution box is connected to the DC motor through a reducer, so that the upper shear blade 41 and the lower shear blade 42 are driven to swing at the same time by the DC motor. When the upper shear blade 41 and the lower shear blade 42 overlap, the steel plate is sheared. The upper crankshaft and the lower crankshaft are provided with shear blade encoders, which can detect the position of the shear blade at any time and control the crank speed. The flying shear machine is provided with relative guide rollers and measuring rollers in front of the upper shear blade 41 and the lower shear blade 42, and the steel plate passes between the guide rollers and the measuring rollers. A length detection encoder is also installed on the measuring roller through a coupling. The length detection encoder is used to measure the length of the steel strip passing through. The length detection encoder is electrically connected to a controller, and the controller electrically controls the DC motor and the shear blade encoder. The controller controls the DC motor according to the speed of the steel plate passing through, and changes the rotation speed of the upper shear blade 41 and the lower shear blade 42, so that when the upper shear blade 41 and the lower shear blade 42 enter into engagement, the length of the steel plate passing through is exactly the length of the predetermined small steel block required, and at the same time, the horizontal speed component of the shear blade is exactly equal to the speed of the steel plate, so as to achieve accurate shearing of the steel plate.

[0045] The stacking device 5 is located at the end of the trimming and leveling flying shear automatic production line. The small steel blocks cut by the flying shear device 4 are conveyed by the finished product conveyor belt. A stacking table 51 is provided at the end of the finished product conveyor belt. Side baffles 52 are provided on both sides of the stacking table 51. The small steel plates pass through the finished product conveyor belt and enter the stacking table 51 to achieve stacking and palletizing.

[0046] The implementation principle of an automatic production line of a trimming and leveling flying shear in the embodiment of the present application is as follows: The production process of steel plates and the flow diagram of the equipment used are as follows: Steel coil--loading (loading trolley 11)--raw material uncoiling (uncoiler 12, auxiliary support mechanism 13)--preliminary leveling (leveling mechanism 21)--head cutting (head cutting shear mechanism 22)--deviation correction and centering (deviation correction mechanism 31)--slitting edge (slitting mechanism 32)--waste edge collection (vertical waste collection mechanism 6)--precise leveling (leveling mechanism 33)--protective film coating (film coating device)--flying shear block (flying shear mechanism)--stacking and palletizing (stacking device 5).

[0047] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
