Abstract

The invention discloses a hydraulic/mechanical hybrid servo press transmission system. The system comprises a motor (1), a hydraulic pump (2), an oil tank (3) and a hydraulic motor (9). The motor (1) drives the hydraulic pump (2), the hydraulic pump (2) and the hydraulic motor (9) form a closed hydraulic circuit, an oil inlet of the hydraulic pump (2) is connected with an oil outlet of the hydraulic motor (9) through a pipeline, the hydraulic pump (2) supplies oil to the hydraulic motor (9) through the pipeline, and the oil tank (3) supplies oil to the system through the pipeline. The hydraulic motor (9) drives a crankshaft (12) to rotate, and the crankshaft (12) drives a slider (13) on a press (11) to move up and down. System safety is guaranteed by additional arrangement of an overflow valve (6). By comprehensive application of mechanical/hydraulic hybrid transmission, the hydraulic/mechanical hybrid servo press transmission system has advantages of high driving power, easiness in pressure and speed control, high stability, energy saving, high flexibility and the like.

Description

technical field [0001] The invention relates to a press servo transmission system, in particular to a hydraulic / mechanical hybrid drive servo press transmission system. Background technique [0002] A press is a piece of equipment used for metal forming. It has the characteristics of wide application and high production efficiency, and is widely used in cutting, punching, blanking, bending, riveting and forming processes. Processed into parts by applying intense pressure to a metal blank to cause the metal to plastically deform and fracture. When the mechanical press is working, the motor drives the large pulley (usually doubled as a flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. In order to overcome the shortcomings of traditional presses, in recent years, servo control technology has been applied to presses to form servo presses. Servo presses generally re...
