Aluminum alloy casting electroplating production equipment and production process thereof

Abstract

The invention relates to the technical field of aluminum alloy casting electroplating machining, in particular to aluminum alloy casting electroplating production equipment. The equipment comprises achemical oil removal pond, a cleaning pond and a machine body, all of which are sequentially arranged in the material running direction. A grinding cavity is arranged in the machine body. The upper end of the machine body is detachably connected with a sealing cover. An air pump is arranged on the outer side of the machine body. A suction pipe is connected to the air pump, and the suction pipe isconnected in the machine body in a penetrating and inserted manner and extends into the grinding cavity. A beating seat used for containing an aluminum alloy casting is arranged on the bottom wall ofthe grinding cavity, and grinding mechanisms are arranged in the grinding cavity. The equipment comprises the following steps of feeding, cleaning, chemical oil removal, cleaning and grinding. When the equipment grinds the aluminum alloy casting, the sealing cover and the machine body are matched, then the air pump is used for sucking air in the grinding cavity out, the aluminum alloy casting canbe ground under the vacuum state, an oxidation film on the surface of the aluminum alloy casting can be fully removed, and the electroplating effect is better.

Description

technical field [0001] The invention relates to the technical field of electroplating processing of aluminum alloy castings, in particular to an electroplating production equipment for aluminum alloy castings and a production process thereof. Background technique [0002] There is a certain difference between aluminum alloy electroplating and ordinary electroplating process. Because aluminum alloy is a relatively active metal with strong reduction and replacement capabilities, it brings many difficulties to the electroplating process. In the electroplating process, the method of dipping zinc is generally used. preprocessing. And during the pretreatment process, the aluminum alloy castings will be polished and polished to ensure the electroplating effect of the aluminum alloy castings. [0003] For example, the invention patent with the publication number CN106521590A discloses a diamond composite electroplating process for aluminum alloy carcass, including the electroplatin...

Problems solved by technology

[0004] However, when the polished casting is larger, the sanding speed is slower. After one part of the casting is polished, the casting is still in the process of grinding, so the polished part will undergo oxidation reaction with the air. The aluminum alloy casting A layer of aluminum oxide film will be produced on the surface, which will affect the subsequent electroplating effect
