Processing of copper alloy castings

Key modeling tools for copper alloy castings. Mould not only has different classification and characteristics, but also has essentially different structure. The structure design, blank selection, machining quality, electroplating quality, assembling quality, maintenance quality and pickling quality of graphite die for copper and copper alloy casting are discussed. Through the practice of the coke oven production sand mould low pressure casting copper alloy castings, in the thick wall surface sand with sand mixed with iron pills, accelerated cooling, riser and mould with asbestos gasket is separated, riser and mould to prevent freezing, and to the change of temperature of the thermocouple thermometer is used to determine the heat preservation time delay, horizontal series casting can not only make the medium and small batch production parts, and greatly improve the production efficiency.

Copper alloy castings arc sphere buffer slag bottom water injection, including the sprue cup, at the bottom of the sprue cup connected fixed connector, connector connected at one end fixed circuitous hollow ball, described circuitous and elbow connected fixed on the bottom of the hollow ball, the bottom of the elbow with the first hollow ball connected fixed, on one side of the elbow and the wheel at the bottom of the slag fixed connecting pipe connections, Wheel slag at the top of the connecting pipe with rectangular groove, the bottom of the wheel slag connecting pipe wall in contact with the two filters, two at the top of the screen pack into rectangular groove, and with the same cross plate bonding fixed, convenient and quick disassembly and fixed two filters, convenient to remove the filter cleaning, time, improve work efficiency, and can meet the needs of use.

Air compressor for deep processing of copper alloy castings. By filtering and drying the air, impurities in the air can be effectively prevented from entering the air compressor, so that impurities can cause damage to the air compressor. At the same time, reduce the water in the air into the first chamber, effectively prevent the air compressor by water corrosion, improve practicality and reliability; The utility model comprises an air storage tank, a bracket, a motor, a first belt pulley, a compressor, a second belt pulley, a belt, a first air pipe and a second air pipe. The inside of the gas storage tank is provided with an empty cavity, the left and right sides of the bottom of the gas storage tank are provided with a support plate, the bottom end of the support plate can be rotated, and is provided with a roller, the top of the gas storage tank is connected with the bottom end of the bracket; The utility model also comprises a filter bin, an installation plate, a sealing plate, a filter screen, two sets of columns, a drying plate, a third air duct and a fourth air duct.
