Abstract

The invention relates to a hydraulic system of a tear bomb powder hydraulic machine. The hydraulic system is characterized in that the hydraulic system of the tear bomb powder hydraulic machine comprises a control system, a cartridge valve system, an auxiliary system and an 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. According to the hydraulic system of the tear bomb powder hydraulic machine, automatic circulation of a series of process actions such as constant-volume filling, pre-pressing, floating pressing, post-pressing, core pulling, demolding and piece taking is achieved, the pressing force, the filling amount, the pressing stroke and the like of the hydraulic system can be accurately adjusted, the repeated locating precision of key positions is smaller than + / -0.05 mm, the size and density consistency and uniformity of products are ensured, and the efficiency is eighteen times that of an original universal hydraulic machine.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system of a tear gas bomb powder hydraulic press. Background technique [0002] Tear gas bomb powder hydraulic press is suitable for automatic dry pressing of powder products such as powder metallurgy and tear gas bombs. It is an indispensable key molding equipment for mass production of products with complex shapes, high molding precision and difficult molding processes in the powder material industry. [0003] However, at present, most of the tear gas bomb molding equipment uses general-purpose presses. The general-purpose presses have complex structures, and the tear gas powder hydraulic process that can be completed only uses split-die hydraulic manufacturing, which has low efficiency and poor precision, resulting in huge production of tear gas bombs. The quality fluctuates, so it is difficult to guarantee the consistency of product performance, which seriously restricts the ...
