The implementation principle of the high-efficiency convenient tilting press provided by the embodiment of the application is as follows: when the workpiece is punched, the starting motor 341 drives the main wheel 343, the auxiliary wheel 344 and the driving wheel 345 to rotate, and the workpiece is placed on the punching table 11. Then, the pedal 52 is stepped on by a foot to drive the ejector rod 53 to slide upwards to jack up the rack 43, so that the rack 43 is meshed with the connecting teeth 41 and then meshed with the rotating transmission teeth 42, and the connection between the transmission shaft 347 and the rotating shaft 31 is established. The rack 43 rotates in the ring groove 152 with the rotation of the driving teeth 42, so that the rack 43 returns to the receiving groove 151 after one rotation and is separated from the driving teeth 42 and the connecting teeth 41. And after the transmission shaft 347 drives the rotation shaft 31 to rotate for one turn, the coaxial connection between the rotation shaft 31 and the transmission shaft 347 is released, and the two ends of the rotation post 32 are abutted against the abutting plate 13, so that the rotation shaft 31 drives the rotation post 32 to rotate for one turn and then stops rotating. The upright post 33 drives the sliding block 21 to slide downwards along with the rotation of the rotating post 32 and then slide upwards to the initial position so as to reset the workpiece after stamping. After the slide block 21 slides downwards and slides away from the proximity switch 18, the controller controls the switch valve to be opened, the air flushing pipe 17 blows air to blow away the punched workpiece on the punching table 11, and after the slide block 21 slides upwards to block the proximity switch 18, the controller controls the switch valve to be closed. After the stamping of the workpiece is finished, the gas flushing pipe 17 stops flushing, so that the situation that the workpiece is clamped on the stamping table 11 and is not easy to take down is reduced, and the stamped workpiece is conveniently taken out.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
