Carbide forging is also known as forging die, with good heat resistance and anti-fatigue ability, which through the upper and lower mold clamping to exert a certain squeeze force, making die forging better mechanical and mechanical properties. There are many types of carbide forging die, mainly classified according to manufacturing equipment, can be divided into tire mold, hammer forging die, forging die, forging die and roll forging die.
Die: for free forging equipment, suitable for small forgings, small and medium production;
Hammer forging die: Forging press equipment under the action of the blank in the forging die boring was forced plastic flow forming, in order to obtain higher than the free forging quality forgings;
Machine forging die: mechanical press is a blank for the die forging or semi-finished products of the mold;
To forging a blank into a die forging or a semi - finished product on a horizontal forging machine;
Rolling forging die: in the roller forging machine will be vertical rolling forming fan-shaped mold, 5 times higher than the hammer forging die.
Compared with the casting, the metal after forging processing can improve its organizational structure and mechanical properties. Casting tissue after forging process thermal deformation due to metal deformation and recrystallization, the original coarse dendrites and columnar grains into fine grain size, uniform size of the equiaxed recrystallization structure, so that the original ingot segregation, Loose, porosity, slag and other compaction and welding, the organization becomes more closely, to improve the plasticity and mechanical properties of the metal. The mechanical properties of the castings are lower than those of the same material. In addition, forging processing to ensure the continuity of metal fiber organization, so that forging the fibrous tissue and forging shape consistent, complete metal line, can ensure that the parts have good mechanical properties and long service life using precision die forging, cold extrusion , Temperature extrusion and other processes for the production of forgings, are castings can not match the forging is the metal is applied pressure, through the plastic deformation of the shape required to shape or the appropriate compression of the object. This force is typically achieved by using a hammer or pressure. The forging process builds fine particle structures and improves the physical properties of the metal. In the practical use of components, a correct design can make the flow of particles in the direction of the main pressure. Castings are made of various casting methods of metal forming objects, that is, smelting a good liquid metal, with casting, injection, inhalation or other casting method into the prepared mold, after cooling down the sand, clean up and after Processing, etc., the resulting workpiece with a certain shape, size and performance.
