Fig. 1 is a schematic diagram of a system for monitoring the movement period of the press ram provided by an embodiment of the present invention, and the following description is made in conjunction with fig. 1.

The working principle of the press is that a small belt pulley on a motor is transmitted to a flywheel of a clutch through a triangle belt, a brake electromagnetic valve and a clutch electromagnetic valve are simultaneously electrified, the flywheel rotates to drive a crankshaft to rotate, the crankshaft transmits motion to a sliding block through a connecting rod, and the sliding block moves downwards from an upper limit point. When the sliding block moves to the lower limit point, the electromagnetic valve of the clutch is powered off, the clutch is disengaged, and the sliding block moves upwards under the driving of the inertia energy of the flywheel. When the brake is close to the upper limit point, the electromagnetic valve of the brake is powered off, and the brake brakes. One stroke of the slide block is completed after the crankshaft rotates for one circle.
