Forging is the process of processing low alloy steel ingots (billets) into rough parts with a certain shape and size using methods such as metal melting, rolling, or rolling.
Castings are a general term for workpieces cast using sand molds or other methods; It is a product made mainly of various cast iron materials, including solid castings filled with molten iron and non hollow castings coated with non iron liquid coatings.
1. Definition difference: Forgings refer to components formed by directly forming liquid metal in a mold using a press, typically used on mechanical components.
2. Different processes: Forging is a forming process that involves applying static loads to metal materials to produce plastic deformation in order to obtain the required geometric shape and mechanical properties.
3. Different characteristics: Forging has the following advantages: 1. High production efficiency; 2. Easy to achieve automation; 3. The overall structure that can be made into workpieces; 4. Can undergo special treatment; 5. Save raw materials; 6. Improve cutting performance; 7. Reduce weight and improve safety; 8. Reduce the wear and tear of machinery and equipment; Reduce production costs.
4. Different uses: Forging is suitable for manufacturing important structural components with low stress but high toughness requirements, such as shafts, rod components, and transmission devices in automotive chassis. Connecting rod bolts, nuts, gears, splines, collars, sprockets, gear rings, flanges, connecting pins, lining plates, rocker arms, fork heads, ductile iron pipe valve seats, gaskets, piston pins, crank sliders, locking mechanisms, connecting plates, spiral grooves, wedges, etc; It can also be used in the mechanical manufacturing industry for a large number of small and medium-sized batch production of ordinary machine tools, bed bodies, workbenches, base boxes, gearbox shells, cylinder heads, cover frames, bearings, support surfaces, guide rails, support brackets, screw and worm gears, and thread dies. In addition, it can be used as a pre preparation for stamping processes and as a pre heating surface quenching medium before heat treatment. In addition, due to the high cooling rate of the material during forging, it is beneficial to improve product quality and production efficiency, and shorten the production cycle.
5. Classification is different: according to different standards, it can be divided into three types: free forging, model forging, and underwater pressing. Underwater pressure forging is mainly used for the production of precision punching and fine drawing parts.
6. Differences in application scope: The application scope of free forging includes the production of precision, complex, thin-walled, and small cross-sectional parts of heavy and medium thickness steel plates, such as the steering knuckle crosshead and brake drum inner cavity main reducer cone rotor clutch and differential gear of automobiles. The main feature of the model is its low cost, which allows for multi-stage upsetting in one process, greatly reducing the cost of single production. It is particularly suitable for the manufacturing of small and lightweight parts, such as valve springs, brake cups, and oil pump plungers in the automotive parts industry.
