The invention discloses a sizing mechanism for shearing of plates. The sizing mechanism comprises a mounting plate, mounting seats and a bidirectional air cylinder are arranged on the mounting plate, and a first driving mechanism and a second driving mechanism are arranged on the bidirectional air cylinder. The first driving mechanism comprises a first supporting seat, a second supporting seat, a third supporting seat and a pushing shaft, a spline shaft and a flange are arranged at two ends of the pushing shaft respectively, a pushing block is arranged on the pushing shaft, and second locking nuts are arranged at two ends of the pushing block. An execution mechanism is further arranged on the mounting plate and comprises fourth supporting seats, a jacking column and a positioning plate, the fourth supporting seats are provided with springs, and the jacking column is provided with balls. The sizing mechanism for shearing of the plates is simple in structure and accurate in positioning; a resultant force applied to the bidirectional air cylinder is decomposed into a radial force along each pushing shaft and an axial force along each pushing shaft by each pushing block, so that the axial force applied to the bidirectional air cylinder is reduced, and the service life of the bidirectional air cylinder is prolonged while accuracy is improved.
Description
technical field [0001] The invention relates to a length-setting mechanism for plate shearing. Background technique [0002] Strip steel has a wide range of uses. It is known as general-purpose steel. It can be cut, separated and pieced together at will, and can withstand deep processing such as stamping and bending. Among them, the blades on the rotary tiller in agricultural production are produced by strip steel. The strip steel used is a straight thick steel plate; at present, in the process of production and processing of this type of steel plate, the shearing machine is manually operated, and the positioning and shearing is carried out by a simple fixture. The shearing efficiency Low, large error in shear size, lack of targeted sizing devices; there are also some automatic devices that use cylinders to achieve sizing, but the cylinders in such devices will bear large axial forces during the process of sizing , due to the heavy weight of the steel plate, the inertia gen...
