Copper door and window casting technology

Abstract

The invention discloses a copper door and window casting technology. The copper door and window casting technology mainly comprises the following steps of selecting materials, opening a mold, then casting precisely by a lost-wax process, adding beewax into the common wax, and setting the wall thickness of a wax mold to be 5mm; deburring, and casting by adopting a replica method; smelting by adopting a medium-frequency induction furnace in casting, after solidifying and cooling of a casting, firstly cleaning mold sand of the casting, then separating a casting body rapidly from the mold sand of the casting by a carbon arc air gouging cutting and pouring system, and performing manual polish-grinding and surface treatment, namely, coping residual copper particle linetypes and oxidized sundries at flower deep hole parts of floriation by a metal engraving flexible-shaft sharpening machine matched with a special diamond grinding head. The copper door and window casting technology has the beneficial effects that doors and windows are beautiful and practical, and are processed finely, an are durable; the copper door and window casting technology is beneficial for improving the product grade, saving materials, and reducing the production cost and the like; in addition, the wall thickness of a casting material is controlled because of novel copper alloy matching; compared with similar products, raw materials are reduced by half, energy sources are saved, and the competitiveness of enterprises is improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of casting, and in particular relates to a copper door and window casting process. [0003] Background technique [0004] The casting process of copper doors and windows mainly includes material selection and mold opening. In the current casting process of the same doors and windows, the finished castings produced are not high in corrosion resistance and need to be coated with anti-corrosion coatings. Not only are there more casting processes, which affects production capacity, but also the utilization rate of raw materials is low. High scrap rate. [0005] Contents of the invention [0006] In order to overcome the above-mentioned technical problems existing in the prior art field, the object of the present invention is to provide a copper door and window casting process, which can directly cast copper door and window castings, and the processing and manufacturing process is simple.
