Abstract

The invention discloses a piston one-time forming process method. The method comprises the step that blank materials are prepared, wherein mixed materials are provided, and the mixed materials comprise the components of 100-200 kg of iron powder, 12-20 kg of copper powder, 7-10 kg of graphite, 10-15 kg of kaolin, 1-5 kg of manganese sulfide, 5-10 kg of differential wax, 0.2-0.5 kg of bobbin oil and 5-10 kg of a binding agent. The method has the advantages that the prepared materials are adopted during pressing one-time forming so that the strength of a piston can be guaranteed, the preparationprocess of the piston can be more efficient, the use requirements of different fields are met, the binding agent is added in the material proportioning process, so that the prepared materials of themethod are more adhesive, and the phenomenon that the center of the pressed piston is prone to being hollow and bloated during pressing is avoided.

Description

technical field [0001] The invention relates to a preparation method, in particular to a piston one-time forming process. Background technique [0002] Powder metallurgy is a technology for producing metal or using metal powder as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has good strength and can carry out continuous production. Due to the advantages of powder metallurgy technology , making the use of powder metallurgy continue to expand, and plays a pivotal role in the development of new materials. However, the preparation process of many powder metallurgy is cumbersome, and the adhesion degree produced by many powder metallurgy preparation processes is not enough, the anti-oxidation ability of the pressed piston is not good, and the outer surface is prone to rust spots. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency, an...
