Problems solved by technology
The latter oil cylinder is placed inside the equipment, and it is very inconvenient to deal with oil leakage. At the same time, the oil cylinder directly drives the upper and lower shear blades for shearing, which requires a large driving force, which is too large in the selection of the oil cylinder. In addition, double-action shears are generally on the operation side and the transmission side Driven by two oil cylinders, involving synchronization issues, a rack and pinion synchronization mechanism is required, which increases equipment space and cost

The invention relates to a pair of double-acting scissors with an external oil cylinder and large opening degree. The double-acting scissors comprise a frame, two supports, two bases, two oil cylinders, two push rods, two sliding blocks, four first connecting rods, four second connecting rods, an upper cutter seat, an upper scissor blade, a lower scissor blade and a lower cutter seat. The two supports are arranged at the upper and lower ends of the side of the frame respectively, and are provided with the bases. The oil cylinders arranged on the bases are flexibly connected with the push rods. Each push rod is flexibly connected with one end of the first connecting rod and the second connecting rod respectively. The upper scissor blade is arranged on the upper cutter seat horizontally, and the lower scissor blade is arranged on the lower cutter seat. The two sliding blocks are arranged on the inner side of the frame correspondingly. The two ends of the upper cutter seat and the lower cutter seat are located in grooves of the sliding blocks. The double-acting scissors are simple and compact in structure, small in occupied space, convenient to maintain, and particularly convenient to solve the problem of oil leakage of the oil cylinders; synchronization of the transmission side and the operation side is good, and a synchronization mechanism can be omitted.
Description
technical field [0001] The invention relates to a double-action shear with an external oil cylinder and a large opening. Background technique [0002] On the cold-rolled strip steel production line, it is usually equipped with a shearing device for coil splitting and cutting off the head and tail, and sometimes it is also used for slitting in the event of piled steel or broken strip accidents, which is indispensable in the production of strip steel. device of. There are two kinds of existing technical solutions: single-action shears with fixed upper shear blades and shearing with lower shear blades, and double-action shears with built-in oil cylinders directly pushing the upper and lower shear blades for shearing. The former has a limited opening due to the fixed upper cutting edge, and often scratches the cutting edge when encountering upturned heads, broken belts and flicking tails. The latter oil cylinder is placed inside the equipment, and it is very inconvenient to de...
