Sheet material micro-forming device by use of high-pressure water jet

Abstract

The invention provides a sheet material micro-forming device of a high-pressure water jet, comprising a high-pressure system, wherein the high-pressure system is connected with a jet flow forming system; the high-pressure system is used for providing high-pressure water to the jet flow forming system; an charging system, the jet flow forming system, a drying system, a fetching system and a worktable are mounted on a bracket; the charging system and the fetching system work by utilizing a pneumatic adsorption way; an upper rotary disc performs 90-degree rotation at intervals since a movable material cylinder is put on a fixed bracket; the time interval between two times of rotation is one period and each period is divided into two stages, including an upper rotary disc rotating stage and an upper rotary disc non-rotating stage; in the upper rotary disc rotating stage, the charging system, a sheet material edge pressing system, the jet flow forming system, the drying system and the fetching system do not work; in the upper rotary disc non-rotating stage, the charging system, the sheet material edge pressing system, the jet flow forming system, the drying system and the fetching system start to work. The micro-forming device provided by the invention reduces the manufacturing cost and can realize automatic production on a large scale.

Description

technical field [0001] The invention relates to the technical field of plastic forming, in particular to a high-pressure water jet plate micro-forming device. Background technique [0002] With the rapid development of micro-processing technology and ultra-precision machining technology of semiconductor integrated circuits, there are more and more researches on micro-devices, and the demand is also increasing. The requirements for the processing technology and processing quality of micro-devices are increasing. High, especially in the small shell parts with complex configurations, such as: the packaging shell of micro devices, the external structural shell of micro mechanisms, etc. For thin-walled miniature and complex surface shell parts, the traditional machining method cannot be processed due to the thin wall of the part and the large amount of machining deformation; the electrochemical method is used for high manufacturing cost and low efficiency; stamping is the An eff...
