Problems solved by technology

Some servo press drive mechanisms use two servo motors for redundant drive, but the two servo motors must be synchronized at all times to avoid motion interference caused by input asynchrony
Although this can increase the inpu

Abstract

The invention discloses a mechanical multi-link servo press driven by six parallelly-connected motors, which belongs to the technical field of forging machines. The mechanical multi-link servo press comprises a rack, three sets of same linear drive mechanisms, a TDOF (three degree of freedom) parallel mechanism, a toggle link mechanism and a stamping slide block, wherein the three sets of linear drive mechanisms are connected with the parallel mechanism, the toggle link mechanism is respectively connected with the TDOF parallel mechanism and the stamping slide block, and the rack is connectedand sleeved on the outer sides of the drive mechanisms and the stamping slide block. The mechanical multi-link servo press disclosed by the invention has the advantages of simple structure and low manufacturing cost, is easy to control, and can solve the problem that that a large tonnage servo press cannot be structured because the traditional servo press is limited by the small carrying capacityof a ball screw and the small power and output torque of a servo motor.

Description

technical field [0001] The invention relates to a device in the technical field of forging machinery, in particular to a six-motor parallel drive mechanical multi-link servo press. Background technique [0002] Presses are widely used forging equipment in the field of metal forming processing. There are many varieties and quantities, among which mechanical presses are the most widely used. The development of modern manufacturing technology requires that the press can not only operate at high speed, high precision and large load, but also have greater flexibility, and can change the output motion law quickly and conveniently. The traditional mechanical press has single motion characteristics and poor process applicability. In recent years, with the gradual development of AC servo motor-driven forming equipment technology, various AC servo-driven presses with adjustable slider motion curves have appeared, which has greatly improved the working performance and process applicab...
