Working principle: By placing the workpiece to be processed between the upper and lower ratchet wheels, and then starting the motor through the controller, the motor drives the rotation of the screw rod, and through the rotation of the screw rod, the upper and lower ratchet wheels are rotated to the required punching hole diameter. The punching head is perpendicular to the hydraulic rod. At the same time, the hydraulic pump is started until the hydraulic rod is slowly pressed down, and the through hole and the round hole are engaged with the punching head in turn, and then continue to press down to the top of the workpiece. After confirmation, start the clamping mechanism to clamp the work, and then continue to start the hydraulic pump to continue pressing the hydraulic rod until the end of the pressure hole. When the diameter of the pressure head needs to be changed, just start the hydraulic pump to shrink the hydraulic rod. At the same time, when the hydraulic rod is raised and recovered, when passing through the circular hole, since the diameter of the punching head is larger than the diameter of the circular hole, the punching head will encounter obstacles when passing through the circular hole, so that the hydraulic rod continues to rise, and the force All the buckles on the lower hydraulic rods will be detached from the punching head, and the punching head will be adsorbed on the bottom of the round hole again under the action of the magnetic force for the next use. At the same time, after the hydraulic rod is fully raised, it will completely separate from the through hole. After that, start the motor until the screw rod rotates, and drive the upper and lower ratchets to rotate to the required diameter of the punching head, so that the operation can be repeated.
