Through the slope of section board 231 and arrange, be convenient for transmit, after the pressure release is accomplished, the repulsion of electro-magnet 232 to section board 231 disappears, and hydraulic oil strikes between the contained angle gap of section board 231 and extension, drives section board 231 and descends, improves the sensitivity that intercepts.
The working principle of the invention is as follows: the workpiece 4 is automatically compressed and sheared respectively through the split design of the pressing component 32 and the shearing knife 31, so that the compression time is reduced, and the shearing efficiency of the workpiece 4 is improved through a mode of firstly compressing and then shearing; the main cutting roller 322 is firstly contacted with the middle section of the workpiece 4, along with the increase of hydraulic pressure, the workpiece 4 is precompressed, at the moment, the hydraulic cylinder 21 can keep larger displacement output speed, at the moment, the reversing cylinders 325 at the two ends of the workpiece 4 are in an unpowered state and do not output displacement, the workpiece 4 is in an unbalanced pressure state, the upper side forms an m-like shape, the middle is low, bulges are formed at the two sides, the inner side of the auxiliary cutter 323 is upwards moved through the bulge transmission at the two sides until the auxiliary cutter 323 is abutted with the rotary cavity 3212, the reversing cylinders 325 output displacement and drive the auxiliary cutter 323 to gradually restore to the horizontal position, at the moment, the telescopic cylinder 324 is in an unpowered form and does not work on the workpiece 4, and the workpiece 4 is secondarily compressed through double-end acting, so that the final compressed shape forms an wave-like shape; in the compression stroke, the hydraulic cylinder 21 keeps higher descending speed, when the compression allowance of the workpiece 4 is smaller, the shearing knife 31 receives larger reverse acting force, the instantaneous acceleration in the core path of the auxiliary shearing knife 323 is increased through transmission, the sliding core 235 moves downwards under the inertia effect, the sub-coil 236 performs cutting magnetic induction line movement, and the instantaneous state of the shearing knife 31 entering the shearing stroke is monitored through movement feedback, so that impact damage caused by the excessive speed is prevented; according to the shearing force of shearing knife 31 is controlled according to the shearing requirement, the descending speed of shearing knife 31 is controlled, the descending speed is prevented from being too fast, impact is caused, the service life is influenced, when the speed is required to be reduced, stop groove 1132 is opened by controlling stop plate 231 and electromagnet 232, high-pressure hydraulic oil flows out from pressure relief port 2121 through bypass pipe 22 and leakage flow channel 1131 in sequence, instantaneous pressure relief is carried out, and impact damage is reduced.
