Copper plate has a high-precision copper plate and wrought copper plate, from the surface of the copper plate can be seen, today we will talk about the wrought copper plate is how the production process.
1, melting: electrolytic copper into a high-temperature furnace, heating to melt into liquid copper water.
2, casting molding: by the upper lead furnace will be copper water lead into the pre-selected mold cavity, forming a fixed shape.
3, cooling molding: the fixed shape at room temperature cooling, molded copper is called casting copper blanks.
4, embryo cutting: according to the specifications of the required product size, to the quality of the constant factor, the copper embryo material for the fixed-size cutting, so that after cutting the quality of the copper embryo material and the required product by the magnification of the quality of the margin is equal (because of the copper embryo material cutting, after cutting the quality must be deviated)
5, high-temperature furnace: the cut embryo material will be put back into the high-temperature furnace heating, after 1-2 hours of high-temperature heating, so that the embryo material to reach the softening temperature of copper.
6, free forging: when the embryo material reaches the softening temperature, the high-temperature embryo material will be quickly placed on the free forging machine table, through the forging machine and manual operation and mutual cooperation, forging out the corresponding size of the embryo parts, copper forging in accordance with the principle of 6-sided parallel forging for forging processing, to ensure that the internal stress balance.
7、Cooling:Forging molding workpiece still has high temperature residual heat, so it must be cooled by sand cooling and water cooling, resulting in complete cooling, to exclude the internal thermal stress, to achieve the best physical properties.
