Multi-station hydraulic press hydraulic cushion multifunctional composite hydraulic system

Abstract

The invention discloses a multi-station hydraulic press hydraulic cushion multifunctional composite hydraulic system and relates to the field of machining and manufacturing equipment. The multi-station hydraulic press hydraulic cushion multifunctional composite hydraulic system comprises a hydraulic cushion, a workbench and a driving cylinder used for driving the hydraulic cushion to rise and fall; and the driving cylinder comprises a main driving cylinder body and an auxiliary driving cylinder body. The multi-station hydraulic press hydraulic cushion multifunctional composite hydraulic system further comprises a proportional pressure adjusting valve system, a feedback circuit, a first displacement sensor and a second displacement sensor; the proportional pressure adjusting valve system performs independent pressure adjusting on the main driving cylinder body and the auxiliary drying cylinder body; and the feedback circuit controls the auxiliary driving cylinder body according to detection signals of the first displacement sensor and the second displacement sensor so as to control the displacement components of the two sides of the hydraulic cushion. The multi-station hydraulic press hydraulic cushion multifunctional composite hydraulic system can achieve the action that the hydraulic cushion is independently ejected out and independently returns, and also achieves the function that the multi-cylinder stretching forces of the hydraulic cushion are correspondingly adjustable, and the hydraulic cushion leveling function.

Description

【Technical field】 [0001] The invention relates to the field of mechanical processing and manufacturing equipment, in particular to a multi-functional composite hydraulic system of a hydraulic cushion of a multi-station hydraulic machine. 【Background technique】 [0002] In modern industrial production, the integral mold or split mold stretching manufacturing method for multi-station hydraulic presses is suitable for plate parts of various materials, and can be processed into various shapes by utilizing the ductility of metal. However, during the processing of some parts, the deformation force is asymmetrical during stretching and deformation, and it is easy to form an eccentric load moment, causing the part to be biased and affecting the processing accuracy of the part. 【Content of invention】 [0003] In order to solve the aforementioned problems, the present invention provides a multi-station hydraulic press hydraulic pad multi-functional composite hydraulic system, which ...
