About copper rod forming technology and process, copper rod extrusion precautions, copper rod forming process heat treatment and process principles, etc.
1. Copper rod
What are the materials of copper rods? Copper rod 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, etc.
Before introducing the copper rod forming process and process, let's talk about what are the metal forming processes?
1. Metal solidification forming is customarily called casting. Casting is a process in which molten metal is poured, injected or sucked into a mold cavity, and then solidified to obtain a casting with a certain shape and performance.
2. Metal plastic forming is a processing method that uses the plastic deformation ability of metal materials to produce expected plastic deformation of metal materials under the action of external forces to obtain parts or blanks with certain shapes, sizes and mechanical properties. The process can often be divided into free forging, die forging, sheet metal stamping, extrusion, pressing, etc. Its performance is commonly used in engineering to express the forgeability of metals. The quality of forgeability is commonly measured by two indicators: plasticity and deformation resistance of metal. If the plasticity is high and the deformation resistance is high, the forgeability is good; on the contrary, the forgeability is poor.
3. Metal welding forming process. Welding is a forming method that uses heat or pressure, or both, with or without filler materials, to achieve atomic bonding of metal materials. Usually classified into fusion welding, pressure welding, and brazing.
What are the copper rod forming processes? There are many copper rod forming processes, including extrusion, rolling, continuous casting, drawing, etc.
Copper rod forming process? There are three copper rod forming processes, as follows:
1. Pressing-(rolling)-drawing-(annealing)-finishing-finished product.
2. Continuous casting (upward casting, horizontal or wheel type, crawler type, dipping) - (rolling) - drawing - (annealing) - finishing - finished product
3. Continuous extrusion-stretching-(annealing)-finishing-finished product.
2. Extrusion of copper rod forming process?
1. Types of extrusion: Extrusion is divided into three types: forward extrusion, reverse extrusion and special extrusion.
(1) Forward extrusion: refers to the extrusion behavior in which the extrusion direction of the product is the same as the direction of the extrusion force.
(2) Reverse extrusion: the extrusion direction is opposite to the extrusion force direction.
(3) Special extrusion: refers to other extrusion methods such as hydrostatic extrusion.
2. Characteristics of extrusion:
(1) Characteristics of forward extrusion: Among them, forward extrusion equipment is relatively simple and is the most widely used.
(2) Characteristics of directional extrusion: Reverse extrusion reduces the friction between the ingot and the extrusion barrel, reduces the extrusion force, and can improve the tool life. It is widely used in small and medium-sized extruded products.
