Double servo motor driven multi-link press and working method

Abstract

The invention discloses a double-servo-motor-driven multi-connection-rod press machine and a working method and belongs to the technical field of forging machinery. The press machine comprises a machine frame and a reinforcement transmission working mechanism, wherein the machine frame is arranged on the outside of the reinforcement transmission mechanism. The mechanism is simple and easy to control, and a slide block is stable in speed change in the working journey. Meanwhile, compared with the existing servo press machine, the press machine can remarkably reduce requirements for the power and the output torque of a servo motor, the structure strength and stability are better, the unbalance loading resistance is higher, and the method is suitable to construct the servo press machine with large tonnage.

Description

technical field [0001] The invention relates to a transmission device in the technical field of forging machinery, in particular to a closed double-point servo-driven multi-link press and a working method. Background technique [0002] Presses are the most widely used forging equipment in the field of metal forming processing. There are many models, types, and quantities. Among them, mechanical presses are the most widely used due to their reliable processing accuracy and high processing efficiency. Traditional mechanical presses driven by ordinary asynchronous motors use energy-consuming components such as clutches and brakes to meet basic operating requirements, and use large-scale flywheel mechanisms to store energy in the motor's idle stage, and finally transmit the motion and energy of the motor to the work through the transmission system. The mechanism has fixed working characteristics, poor controllability, high noise, serious energy consumption, poor process adaptabi...

Problems solved by technology

Although the application of the multi-bar mechanism has greatly improved the torque-increasing function of the transmission system, such as the patent of "knuckle-joint press" and the patent of "multi-link press driven by double servo motors in parallel", due to the fact that the multi-bar system itself Design problems. Compared with the traditional crank-link mechanism, its transmission system has poorer stability and poor fault tolerance. It has higher requirements for actual processing and production, which not only increases the difficulty of the corresponding control strategy of the servo control system, but also is not suitable for At present, domestic servo forging equipment is mostly developed on the basis of the crank connecting rod mechanism and its derivatives.
