Description
Technical Field
The invention belongs to the technical field of crank punching machines, and particularly relates to a single-point crank precision punching machine based on servo control.
Background
The punch press is a punching type punch press, and is often used for forming product parts by performing various punching processes on plates by matching with a group of dies arranged on the punch press, and is widely applied to punching and forming of electronics, communication, electrical appliances, furniture, vehicles, hardware parts and the like. When the punching machine works, the lower pressing block drives the upper die to move relative to the lower die, the rotary motion of the crank is converted into linear motion, and the motor drives the gears, the crank (or the eccentric gear), the connecting rod and the like to run and convert the linear motion into the up-and-down reciprocating motion of the sliding block, so that the punching is realized. The punching machines may be classified into a crank type punching machine, a link type punching machine, a toggle type punching machine, a friction type punching machine, a screw type punching machine, a rack type punching machine, a cam type punching machine, and the like according to the difference of the driving mechanism.
The general punch is a circular reciprocating motion, a gear is used as a speed reduction motor to control the movement of the lower pressing block, the pressing distance of the lower pressing block is controlled by the lifting mechanism, the lower pressing block cannot be accurately stopped and lifted, and if precise integrated plates need to be produced, the punch needs to be controlled highly.
