Abstract
The utility model discloses a press machine which comprises a base frame, ball screw pairs vertically arranged on the base frame, an upper pressing plate, a pressure sensor, a lower pressing plate and a driving mechanism used for driving the ball screw pairs. The ball screw pairs comprise ball screws arranged on the base frame in rotating mode and thread inserts sleeved on the ball screws, the lower pressing plate is fixedly arranged on the base frame and below the upper pressing plate, and the upper pressing plate and the pressure sensor are fixedly arranged on the thread inserts. During a pressing process, the ball screws drive the thread inserts to move, and further drive the upper pressing plate to move toward the lower pressing plate. Due to the fact that when moving, the upper pressing plate bears a combined force of the gravity and a downward component twisting force of the thread inserts and the upper pressing plate, the ball screws do not need to overcome the gravity of the thread inserts and the lower pressing plate when driving the upper pressing plate in rotating mode to move downward. Therefore, the twisting fore of driving the ball screws is reduced, furthermore the power consumption of a driving mechanism is reduced, and press power is bigger compared with that of the prior art.
