Abstract

The invention discloses a numerical control servo press machine with a non-circular gear transmission mechanism, which comprises a servo motor (2), a connection device (16), a gear transmission mechanism (17) and a crank slider mechanism (18); wherein the output end of the servo motor (2) is connected with the connection device (16), and the connection device (16) is connected with the crank slider mechanism (18) through the gear transmission mechanism (17); and the gear transmission mechanism (17) comprises a non-circular gear set, which is used for changing the transmission ratio of the servo press machine and comprises a first non-circular gear (5) and a second non-circular gear (7), and the first non-circular gear (5) and the second non-circular gear (7) are meshed with each other. By means of the coordination of the servo motor and the non-circular gear set, the movement of a crank in the crank slider mechanism is regulated in real time so that the crank continuously moves and swings in cycle, thus, different motion characteristics of a slider connected with the crank is realized, and the process adaptability and the production efficiency of the press machine are improved.

Description

technical field [0001] The invention relates to a press machine, in particular to a numerical control servo press machine with a non-circular gear transmission mechanism. Background technique [0002] In ordinary presses, the motor drives the flywheel to accelerate rotation through a fixed transmission ratio mechanism such as a pulley and a gear, and the crankshaft is driven by the rotational inertia of the flywheel to rotate, and the stamping function is realized through a slider connected to the crankshaft. The speed and position of the slider cannot be controlled when forging the workpiece. Therefore, the process adaptability of the press is poor, the structure is complex, the work efficiency is low, the noise is large, and the safety is poor. Contents of the invention [0003] In view of the above technical problems, the present invention provides a CNC servo press with a non-circular gear transmission mechanism, through the coordinated configuration of the servo moto...
