When the invention is applied to a metal plate shearing production line, continuous plates are fed between the upper end scissors 22 and the lower end scissors 42 under the conveying action of a sizing feeder, and the plates are supported by front end guide rollers 512 and rear end guide rollers 522 which are arranged front and back; after the plate material is delivered in place, the left end driving oil cylinder 311 and the right end driving oil cylinder 321 act, the left end driving oil cylinder 311 pushes the upper tool apron 21 downwards through the left end driving connecting rod 312, the right end driving oil cylinder 321 pushes the upper tool apron 21 downwards through the right end driving connecting rod 322, the upper tool apron 21 moves downwards under the driving of the left end driving oil cylinder 311 and the right end driving oil cylinder 321, the upper tool apron 21 which moves downwards drives the upper scissors 22, the front end roller mounting seat 511, the front end guide roller 512, the rear end roller mounting seat 521, the rear end guide roller 522 and the shearing and compacting assembly 7 to synchronously move downwards, in the process, the front end guide roller 512 and the rear end guide roller 522 firstly move downwards below the supporting surface of the lower tool apron 41 and enable the plate material to be placed on the upper surface of the lower tool apron 41, then the soft rubber pad 76 is compacted and the plate material is compacted along with the continuous downward movement of the upper tool apron 21, at the moment, the springs 75 are compressed and are compacted and fixed between the soft compacting pad 76 and the lower tool apron 41, and the upper scissors 22 are combined with the lower scissors 42 along with the continuous downward movement of the upper tool apron 21; after the plate is driven by the front end, the left end driving oil cylinder 311 and the right end driving oil cylinder 321 act reversely and drive the upper tool apron 21, the upper end scissors 22, the front end guide roller 512, the rear end guide roller 522 and the shearing compaction assembly 7 to move upwards for resetting, and in the process, the resetting elastic force of the spring 75 also drives the lifting guide rod 72 to reset.
It should be emphasized that the upper scissors 22 of the present invention are disposed obliquely, and in the process that the upper scissors 22 contact the plate and cooperate with the lower scissors 42 to cut the plate, the left end of the upper scissors 22 contacts the plate and cuts the left end of the plate, and the upper scissors 22 cut the plate from left to right as the upper knife holder 21 moves down. In the working process of the invention, the left end driving oil cylinder 311 and the right end driving oil cylinder 321 are driven by the hydraulic component 6, and the specific process is as follows: in the process that the left end driving oil cylinder 311 and the right end driving oil cylinder 321 drive the upper tool apron 21 to move downwards, hydraulic oil pumped by the servo pump station 61 is supplied to the upper chamber of the left end driving oil cylinder 311 through an oil inlet P of the two-position four-way electromagnetic valve 62, an oil outlet B of the two-position four-way electromagnetic valve 62 and an oil outlet B of the left end driving oil cylinder 311, at the moment, a piston of the left end driving oil cylinder 311 moves downwards and enables a piston rod of the left end driving oil cylinder 311 to push the upper tool apron 21 downwards, in the process, hydraulic oil in the lower chamber of the left end driving oil cylinder 311 is pressed into the upper end oil port of the right end driving oil cylinder 321 through a lower end oil port and a hydraulic pipeline 64, so that hydraulic oil in the lower chamber of the left end driving oil cylinder 311 enters the upper chamber of the right end driving oil cylinder 321, at the moment, the piston of the right end driving oil cylinder 321 moves downwards and enables the piston rod of the right end driving oil cylinder 321 to push the upper tool apron 21 downwards, and hydraulic oil in the lower chamber of the right end driving oil cylinder 321 flows back into the servo pump station 61 through the lower end oil port, the oil outlet A of the two-position electromagnetic valve 62 and an oil outlet T of the two-position four-way electromagnetic valve; when the left end driving oil cylinder 311 and the right end driving oil cylinder 321 drive the upper tool apron 21 to move upwards for resetting, the two-position four-way electromagnetic valve 62 acts, hydraulic oil pumped by the servo pump station 61 is supplied to the lower chamber of the right end driving oil cylinder 321 through the oil inlet P of the two-position four-way electromagnetic valve 62, the oil outlet A of the two-position four-way electromagnetic valve 62 and the oil outlet of the right end driving oil cylinder 321, at this time, the piston of the right end driving oil cylinder 321 moves upwards and enables the piston rod of the right end driving oil cylinder 321 to pull the upper tool apron 21 upwards, in the process, hydraulic oil in the upper chamber of the right end driving oil cylinder 321 is pressed into the lower end oil outlet of the left end driving oil cylinder 311 through the upper end oil outlet and the hydraulic pipeline 64, so that hydraulic oil in the upper chamber of the right end driving oil cylinder 321 enters the lower chamber of the left end driving oil cylinder 311, at this time, the piston rod of the left end driving oil cylinder 311 moves upwards and enables the piston rod of the left end driving oil cylinder 311 to pull the upper tool apron 21 upwards, and hydraulic oil in the upper chamber of the left end driving oil cylinder 311 returns to the servo pump station 61 through the upper end oil outlet B of the four-position electromagnetic valve 62 and the oil outlet T.
It should be noted that, in the process that the left end driving oil cylinder 311 and the right end driving oil cylinder 321 drive the upper tool apron 21 to move up and down, the left end driving oil cylinder 311 and the right end driving oil cylinder 321 are linked and realize the synchronous action of the left end driving oil cylinder 311 and the right end driving oil cylinder 321 through the action of the hydraulic component 6; the cross areas of the inner chambers of the left end driving oil cylinder 311 and the right end driving oil cylinder 321 are the same. When the left end driving cylinder 311 and the right end driving cylinder 321 drive the upper tool apron 21 to move downwards to the lower limit position, the two-position four-way electromagnetic valve 62 keeps the state when the upper tool apron 21 moves downwards, the electromagnetic ball valve 63 is opened at the moment, hydraulic oil enters the hydraulic pipeline 64 between the lower end oil port of the left end driving cylinder 311 and the upper end oil port of the right end driving cylinder 321, so that the lower chamber of the left end driving cylinder 311 and the upper chamber of the right end driving cylinder 321 are fully filled with the hydraulic oil, and the reliability of synchronous action of the subsequent left end driving cylinder 311 and right end driving cylinder 321 is ensured.
It should be explained that, for the metal sheet shearing production line, a PLC controller electrically connected to an external power source is configured, and the PLC controller is electrically connected to the servo pump station 61, the two-position four-way electromagnetic valve 62, and the electromagnetic ball valve 63 respectively; when the intelligent control system works, the PLC controls the servo pump station 61, the two-position four-way electromagnetic valve 62 and the electromagnetic ball valve 63 to act according to an internal program.
