Abstract

The invention discloses an optimizing method for a transmission mechanism of a toggle rod servo press. The toggle rod servo press comprises a servo motor, a rack, an upper connecting rod, a lower connecting rod, a crank, a triangular rod piece and a sliding block. A drive output shaft of the servo motor is connected with one end of the crank, and the other end of the crank is connected with one top point of the triangular rod piece. The other two top points of the triangular rod piece are connected with the lower end of the upper connecting rod and the upper end of the lower connecting rod correspondingly. The upper end of the upper connecting rod is connected with the rack, and the lower end of the lower connecting rod is connected with the sliding block. In the triangular rod piece, a rod piece body connecting the crank with the upper connecting rod serves as an upper rod, a rod piece body connecting the crank with the lower connecting rod serves as a lower rod, a rod piece body connecting the upper connecting rod with the lower connecting rod serves as a bottom rod, and the lengths of the crank, the upper rod, the lower rod, the bottom rod, the upper connecting rod and the lower connecting rod are L1, L2, L3, L4, L5 and L6 correspondingly. The optimizing method comprises the first step of optimization scheme determining, the second step of optimization of the rod length L2 of the upper rod and the rod length L4 of the lower rod, and the third step of example verification passing.

Description

technical field [0001] The invention relates to a method for optimizing the transmission mechanism of a press using a toggle mechanism and cam transmission. Background technique [0002] Servo Press is a third-generation press that appeared internationally in the 1990s with a completely different concept from traditional mechanical presses. Based on the abandonment of energy-consuming components such as flywheels and clutches of traditional mechanical presses , the AC servo motor is used directly as the power source of the press, and the rotary motion of the motor is converted into the linear motion of the slider through multi-link actuators such as screw, crank, and toggle. In the toggle actuator, as The servo press of the third generation of presses has the advantages of flexibility, high precision, high efficiency, and low noise. It is more practical to establish a conservation-oriented Chinese society, and the research on servo presses has important scientific significa...
