Casting: It is the transformation of a shapeless molten metal into a shaped solid. Forging: The transformation of a solid of one shape into a solid of another shape.
1. The difference between forging and casting
(1) Conceptual differences
Casting: It is the transformation of a shapeless molten metal into a shaped solid.
Forging: The transformation of a solid of one shape into a solid of another shape.
Casting is like playing with wax. You buy wax (scrap steel, or pig iron) and then you turn this wax into a liquid and put it in a mold, so you get different shapes. (solid-liquid-solid)
Forging is like the process of making bread. You knead small dough and put it into a mold to make products of different shapes. Almost solid at high temperature, the shape can change to other shapes (solid to solid).
The so-called casting is the process of casting molten metal into the model. The casting profession focuses on the metal melting process and the control of the casting process.
Forging is plastic forming in solid state, which is divided into hot working and cold working, such as extrusion, drawing, pier thickness, punching, etc.
(2) Forging is slowly forming, and casting is a forming.
Casting: The molten liquid metal fills the cavity and cools it. Porosity is easy to occur in the middle of the workpiece.
Forging: mainly at high temperatures with the method of extrusion molding. The grains in the article can be refined.
2. The difference between free forging and die forging
Free forging is a kind of processing method in which the heated metal blank is placed on the upper and lower metal of the forging equipment, and the impact force or pressure is applied to directly cause the blank to produce plastic deformation, so as to obtain the required forging. Due to the simple shape and flexible operation, free forging is suitable for the production of single piece, small batch and heavy forgings. Free forging is divided into manual free forging and machine free forging. Manual free forging production efficiency is low, labor intensity, only for repair or simple, small, small batch of forgings production, in modern industrial production, machine free forging has become the main method of forging production, in heavy machinery manufacturing, it has a particularly important role.
Die forging is called model forging, and the heated blank is placed in a forging die fixed on the die forging equipment.
Swaging can be performed on a variety of equipment. In industrial production, steam-air hammer is mostly used for die forging on the hammer, with a tonnage of 5KN ~ 300KN(0.5~30t). Die forging on the press commonly used hot die forging press, tonnage in 25000KN ~ 63000KN.
The forging die structure of die forging includes single-mode hall forging die and multi-mode bore forging die. As shown in Figure 3-13, it is a single-mode hall forging die. It uses dovetail groove and inclined wedge to fix the forging die to prevent it from falling out and moving left and right. The combination of key and keyway can make the forging die position accurately and prevent it from moving back and forth. The single-mode bore is generally a final forging die bore, and it is often necessary to air hammer the blank for forging, and then the final forging die bore is hammered for many times, and finally the forging is taken out to cut off the flash.
3. The difference between casting, forging, stamping and die casting
(1) casting is to melt the raw materials to let them form naturally in the forming mold;
Forging is to heat the raw material to a certain temperature and then use tools to forge and form;
Stamping is the raw material with a suitable stamping die stamping forming;
Die casting is based on the use of pressure to melt the raw materials into the mold to get a higher density or more precise shape;
Casting: The molten liquid metal fills the cavity and cools it. Porosity is easy to occur in the middle of the workpiece.
(2) Forging: It is mainly formed by extrusion at high temperature, which can refine the grains in the parts.
The thickness of the part is basically equivalent to that of stamping suitable for forming from sheet metal.
Parts with great thickness, complex shape, not heated, die casting.
