Problems solved by technology

[0004] At present, the aluminum die-casting blank housing of the self-sealing magnetic oil-absorbing filter is usually made of aluminum alloy through die-casting, but the wear resistance of aluminum castings is poor, and it is easy to cause damage when in contact with tools or equipment during production or transportation. wear, thereby shortening the service life of filters assembled from aluminum castings, and therefore still leaves room for improvement

Abstract

The invention relates to the field of aluminum castings, and discloses a self-sealing magnetic oil absorption filter aluminum die-casting blank shell and a machining process thereof. The self-sealing magnetic oil absorption filter aluminum die-casting blank shell comprises a shell body, and the shell body is treated with a surface treating agent. The preparation method comprises the following steps of S1, polishing, S2, preparing a surface treating agent, S3, conducting electrostatic spraying, and S4, high-temperature curing. The machining process has the following advantages and effects that the polytetrafluoroethylene is mixed in the polyamide resin, and a solid lubricating film can be formed on the surface to reduce the friction coefficient so as to increase the wear resistance when the resin is abraded with other materials; propylene glycol fatty acid ester can react with polyamide resin to generate a certain plasticizing effect, cohesive energy among molecules in the resin is reduced, mutual friction between the polyamide resin and polytetrafluoroethylene components is weakened, so that polytetrafluoroethylene is uniformly dispersed in the resin, and the purpose of improving the wear resistance of a coating formed by the surface treating agent is achieved.

Description

technical field [0001] The present application relates to the field of aluminum castings, in particular to a self-sealing magnetic oil suction filter aluminum die-cast blank shell and its processing technology. Background technique [0002] Self-sealing magnetic oil suction filter, usually placed on the oil suction side of the pump, through the filter element to filter out solid particles and colloidal substances in the working medium, and the filter element is a permanent magnet, used to filter out iron filings, iron powder and other magnetic materials , so as to effectively control the pollution degree of the working medium, prevent impurities from entering the system, keep the pump and system clean, prolong the service life of the pump and system, and reduce obstacles caused by continuous operation. [0003] Aluminum die-casting is a pressure-casting part. Using a pressure-casting machine die-casting machine equipped with a casting mold, the aluminum or aluminum alloy hea...
