Abstract

The invention discloses a double-toggle double-motor parallel-drive toggle rod mechanism and a control method thereof. The double-toggle double-motor parallel-drive toggle rod mechanism is a two-freedom parallel mechanism including a double-toggle bearing mechanism, an upper toggle regulating mechanism, a lower toggle regulating mechanism; the double-toggle bearing mechanism comprises two toggles; the upper toggle regulating mechanism and the lower toggle regulating mechanism are distributed at the two ends of the double-toggle bearing mechanism, and are respectively connected with two toggles in the double-toggle bearing mechanism through a drive mechanism and a transmission mechanism to drive two toggles in the double-toggle bearing mechanism to move. According to the double-toggle double-motor parallel-drive toggle rod mechanism, contradiction that a reinforcing effect of a servo mechanical press working mechanism and stroke of a slide block are clamped with each other is solved, biggest stroke of the slide block can be obtained, the servo motor power capacity and the manufacturing cost of the press are reduced; the slide block movement speed, the biggest stoke of the slide block and the slide block lower dead point are adjustable; working performance and process adaptation of the servo press are improved.

Description

technical field

[0001] The invention relates to a dual-knuckle dual-motor parallel-driven toggle mechanism for a servo mechanical press and a control method thereof, which is an innovative design in the field of forging machinery. Background technique

[0002] The stamping mechanism is an important functional part of the mechanical press, and the press that uses an AC servo motor as the driving element of the stamping mechanism is called a servo mechanical press. Compared with the traditional conventional motor-driven mechanical press, the servo mechanical press has the characteristics of controllable slider movement, excellent working performance, high efficiency, energy saving and environmental protection. However, due to the removal of the large flywheel used to store and release mechanical energy, the servo mechanical press completely relies on the instantaneous torque of the servo motor to generate sufficient pressing force to bring the metal workpiece into yield.
