Is there any skill in the processing of copper parts? Copper parts of processing content:

1. Molding processing methods: forging, casting, die casting and so on.

 Copper and Brass Casting: the metal solution directly into the mold and the formation of a certain shape of the metal forming process. The quality is slightly worse.

 Copper and Brass Forging: Castings or other workpieces, after a beat beat or other pressure shocks, etc. to get better strength of the processing technology. This is the product, performance and strength are stronger than the casting.

 Copper and Brass Stamping process: that is, a certain shape of the object, placed in the press machine, punching machine with a mold, punch out of the mold with a good product design.

2. Copper and Brass surface treatment methods: oxidation, plating, PVD and so on.

3. other: polishing, grinding, drawing, sandblasting, welding and so on.

Common technology in copper processing: cold extrusion technology in copper processing is to use mold to control the flow of copper material, relying on the continuous transfer of copper volume extrusion to meet the requirements of the formation of copper parts parts. Cold extrusion is an important part of the precision plastic volume forming technology. Cold extrusion means that the copper blank is placed in the mold cavity under cold state and under the action of strong pressure and constant speed, the copper is forced from the mold cavity Extruded to obtain the desired shape, size and extrusion with a certain mechanical properties. Cold extrusion technology in the new extrusion materials, mold new steel and large tonnage presses will expand the development of its space.

Copper parts of the welding: the main use of arc welding and brazing.

Arc welding: the main sub-melting TIG (MIG), TIG welding (TIG) two, the former for larger size (width, thickness) of the copper plate, which is suitable for smaller size copper pieces.

Brazing: refers to the base metal with a lower melting point than the brazing filler metal and welding together to heat the solder melt (weldment does not melt) after wetting and fill the gap between the base metal, solder and the base material to form a mutual diffusion A solid connection method. Brazing when the base material does not melt, only solder melting. Brazing deformation is small, the joints are smooth and beautiful, suitable for welding precision, complex and composed of different materials, such as honeycomb structure board, turbine blades, carbide cutting tools and printed circuit boards. Before the brazing the workpiece must be carefully processed and strictly cleaned to remove the oil and too thick oxide film to ensure that the interface assembly gap. The gap is generally between 0.01 and 0.1 mm.
