The machine features: 1, the oblique edge structure of three point type guide rail, namely the rest over the cross section through the three point constraint, and the fulcrum for elastic fulcrum, through the front fulcrum spring preload, eliminate the gap of each pair, the parallelism error knife rack rail surface machining can be carried on compensation, so that the stability of the blade gap; three points, on the fulcrum for eccentric pivot adjustable, through an eccentric adjustment, knife around after the fulcrum to rotate, through the leverage effect, blade clearance changes so as to achieve the purpose of adjusting blade clearance. Due to the eccentric regulation in the column outside the driving motor is convenient for adjustment, so adjust the blade gap becomes very convenient, fast. 2, the mechanism of hydraulic cylinder in series two cylinder. Due to the shear cut from left to right change, the load changes, the series oil cylinder can effectively withstand load changes the (anti then loaded), prevent the shear angle changes; due to the application of tandem cylinder, head not to like the pendulum shear torsion load that kind of machine tool, so the relative structure more light. 3, the hydraulic system with cartridge valve integrated mechanism, reliability high, fluid resistance is small, the flow of large flow, a sequence of pressing, the loose material function, prevent "strip". At the same time, the return cylinder head by the accumulator support (act as springs), when the holder to the lower dead point, the main valve electric knife or return, the return speed. At the same time, the accumulator holding, when changing the blade personal safety is greatly improved. Through to the series oil cavity fill oil, can adjust the shear angle, small shear angle during shearing can reduce shear deformation so as to improve the quality of finished products; and in the angle of shear party usually, blade gap blade length uniformity one out, but also to improve the operation safety. |
