A copper rod is a solid copper bar that has been extruded or drawn.
There are many types of copper rods, including copper rods, brass rods, white copper rods, and bronze rods.
Copper rod molding has its own principles. The copper rod molding process can also be described as the copper rod production process. Different types of copper rods will have different molding process with different characteristics.
What are the materials of copper rods? Copper bar materials include H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801, C5191, C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.5-0.1, QSn8-0.3, QSn4-0.3, BZn18-18, BZn15-20, CuBe2 and so on.
Before introducing the copper rod molding process and procedure, let's say what are the metal molding processes?
1, metal solidification molding is customarily called casting. Casting is the molten metal is poured, pressed or sucked into the casting cavity, to be solidified and obtain a certain shape and properties of the casting process.
2, metal plastic forming is the use of metal materials have the ability to plastic deformation, in the role of external forces so that the metal material to produce the expected plastic deformation to obtain a certain shape, size and mechanical properties of the parts or blanks of the processing method.
The process can often be divided into free forging, die forging, plate stamping, extrusion, pressing, etc. Its performance in the engineering commonly used metal forging properties. Good or bad forging, commonly used metal plasticity and deformation resistance of two indicators to measure. High plasticity, deformation resistance, the forging is good; conversely, the forging is poor.
3, metal welding molding process. Welding is by heating or pressurizing or both, and with or without filler material, so that the metal material to achieve an atomic combination of a molding method. Usually categorized as fusion welding, pressure welding, brazing.
So, what are the forming processes for copper rods? There are many copper rod forming processes, including extrusion, rolling, continuous casting, and stretching.
Copper rod molding process flow? There are three types of copper rod molding process flow, as follows
1. Pressing-(rolling)-stretching-(annealing)-finishing-finished product.
2,Continuous casting (top lead, horizontal or wheeled, tracked, impregnated)-(rolling)-stretching-(annealing)-finishing-finished product
3,Continuous extrusion-(stretching)-(annealing)-finishing-finished product.
Copper rod molding process of extrusion?
1, the type of extrusion: extrusion is divided into forward extrusion, reverse extrusion and special extrusion three.
(1) forward extrusion: refers to the extrusion of products in the same direction as the direction of extrusion pressure extrusion behavior.
(2) reverse extrusion: is the direction of extrusion and extrusion pressure in the opposite direction.
(3) Special extrusion: refers to other extrusion methods such as hydrostatic extrusion.
2, the characteristics of extrusion:
(1) the characteristics of forward extrusion: the forward extrusion equipment is simpler, the most widely used.
(2) the direction of extrusion characteristics: reverse extrusion due to reduce the ingot billet and extrusion cylinder friction, reduce the extrusion pressure, can improve the tool life, in small and medium-sized extruded products in the application of more.
(3) The characteristics of special extrusion: special extrusion is mostly used for extrusion of special products.
