[CN 201610295464.9] Hydraulic system of tear gas powder hydraulic press


[CN 201610295464.9] Title of hydraulic system of tear gas powder hydraulic press: Application number of hydraulic system of tear gas powder hydraulic press: CN 201610295464.9 Applicant: Jiangsu Jinze Heavy Machinery Co., Ltd. Application date: 2016-5-6 Patent type: Invention application The present invention relates to a hydraulic system of tear gas powder hydraulic press. Its innovation point is: the hydraulic system of tear gas powder hydraulic press includes: control system, cartridge valve system, auxiliary system and execution system; the control system is connected with the cartridge valve system and the auxiliary system, and the execution system is connected with the cartridge valve system. The hydraulic system of the tear gas powder hydraulic press realizes the automatic cycle of a series of process actions such as constant volume filling, pre-pressing, floating pressing, post-pressing, core pulling, demoulding and taking parts. The pressing force, filling amount and pressing stroke can be accurately adjusted, and the repeated positioning accuracy of key parts is less than ± 0.05mm, it ensures the consistency and uniformity of product size and density, and the efficiency is eighteen times that of the original general hydraulic press.
