Workpiece forming method
The invention discloses a workpiece forming method which comprises the following steps: manufacturing a dry pressing mold according to the structure of a workpiece, and forming a blank of the workpiece through powder by utilizing the dry pressing mold; a wet pressing mold matched with the green body is manufactured according to the structure of the green body, the green body is placed in the wet pressing mold, and a winding film is arranged between the wet pressing mold and the green body; the wet pressing mold and the green body are packaged together through a first plastic bag, the interior of the first plastic bag is vacuumized, and a to-be-pressed piece is formed; and an isostatic press is used for conducting isostatic pressing on the to-be-pressed piece, so that the blank forms the workpiece. According to the workpiece forming method, CNC machining is not needed, machining is easy and convenient, the powder utilization rate is high, the machining efficiency is high, and the cost is low.
本发明公开一种工件成型方法，包括以下步骤：根据工件结构制作干压模具，利用所述干压模具通过粉末成型出工件的坯体；根据坯体结构制作与所述坯体相适配的湿压模具，将所述坯体放置于所述湿压模具中，且在所述湿压模具与所述坯体之间设置缠绕膜；将所述湿压模具及所述坯体用第一塑料袋封装在一起，且对所述第一塑料袋内部抽真空，形成待压件；使用等静压机对所述待压件等静压，使所述坯体形成所述工件。本发明的工件成型方法无需CNC加工、加工简单方便、粉料利用率高、加工效率高、成本低。
