Main drive structure for high-speed servo press

Abstract

The invention discloses a main drive structure for a high-speed servo press. Servo motors are installed on two sides of the upper beam of the press, and are connected with two ends of a gear shaft by splines; a middle gear sleeve is installed on a gear sleeve mandrel, and gear tooth at the middle part of the middle gear sleeve is engaged with a gear tooth at the middle part of the gear shaft; an eccentric gear is installed on an eccentric gear mandrel, and engaged with a gear tooth at the end part of the middle gear sleeve; a connecting rod mechanical is installed on the eccentric gear, and a guide pillar is positioned in a guide sleeve that is installed at the lower part of the upper beam of the press. The main drive structure for the high-speed servo press has the advantages that, the structure is simple and compact, the height of the servo press is reduced, the transmission link is short, the precision is high and the adjustment is easy to perform, and the space between pressing lines can be shortened; the reciprocating variable stroke pressing can be achieved, reduction of the stroke can be achieved, and thereby the pressing time is shortened, and high-speed pressing of the servo press is achieved; the transmission torque is large, the transmission gap is small, and the controllability and the transmission rigidity are good; quantity of the servo motors can be changed according to the requirement of nominal pressure.

Description

technical field [0001] The invention belongs to the main transmission structure of a press, in particular to the main transmission structure of a high-speed servo press. Background technique [0002] Due to the power limit and cost limit of the servo motor, the servo press often needs to increase the transmission ratio of the transmission chain as much as possible to amplify the torque of the servo motor. The disadvantage is: this will affect the control accuracy, and the asymmetric structure of the main transmission structure cannot realize the reciprocating variable-stroke stamping, and the stamping efficiency cannot be greatly improved; large servo presses often require multiple servo motors to work at the same time, and the structural layout It is very difficult, most of them arrange the servo motor on the top of the upper beam, which will make the height of the press too large. Therefore, it is a technical problem in this field to overcome the above-mentioned shortcomi...
