Background
The press is a forging press which adopts a screw mechanism to transfer flywheel energy. The basic part is composed of a flywheel, a screw rod, a nut, a sliding block and a machine body. The flywheel is accelerated and rotated by a motor direct driving device to accumulate energy, and meanwhile, the rotary motion of the flywheel is converted into the up-and-down linear motion without blocks by a screw pair.
The structure of the existing friction press is as follows: a motor is installed on one side of the machine body and drives a balance cylinder to rotate, a flywheel rotates through a friction disc to drive a lead screw to rotate, a sliding block is driven to move up and down through the left-right rotation of the lead screw, the movement of the sliding block applies pressure to a workpiece on a workbench, the workpiece is compressed tightly, and the pressure forming of the metal material workpiece is completed.
The motor of the friction press is driven by a belt and a balance cylinder, and the belt transmission has the defect that high power cannot be transmitted by virtue of friction force transmission. The sliding exists in the transmission, the accurate transmission ratio cannot be maintained, and the efficiency is low. When the same large circumferential force is transmitted, the overall dimension and the stress on the shaft are larger than those of meshing transmission such as gear transmission and the like. The belt is worn quickly and has short service life.
And most of the devices adopt single-screw transmission, the energy consumption is large in the process of lifting the return stroke of the sliding block, the power of a motor for driving the flywheel is overlarge, and a single shaft is easy to break, the energy consumption is large, and the transmission efficiency is high.
