Product Description

 

Forging is a processing method which uses forging machinery to exert pressure on metal billet to produce plastic deformation so as to obtain forging parts with certain mechanical properties, certain shape and size. Forging is a manufacturing process involving the shaping of metal using localized compressive forces.Through forging can eliminate the defects such as loose cast state produced in the smelting process of metal, optimize the microstructure structure, at the same time because of the preservation of a complete metal streamline, the mechanical properties of the forging is generally better than the same material castings. Forgings are mostly used for the important parts with high load and severe working conditions in the relevant machinery, except for the simple plate, profile or welding parts that can be rolled.
The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry.
Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain texture deforms to follow the general shape of the part. As a result, the texture variation is continuous throughout the part, giving rise to a piece with improved strength characteristics. Additionally, forgings can achieve a lower total cost than casting or fabrication. Considering all the costs that are incurred in a product's life cycle from procurement to lead time to rework, and factoring in the costs of scrap, and downtime and other quality considerations, the long-term benefits of forgings can outweigh the short-term cost savings that castings or fabrications might offer.
Different forging methods have different processes, among which the hot die forging process is the longest, the general order is: forging blank blanking; Forging billet heating; Roll forging billet preparation; Die forging; Trimming; Punching; Correction; Intermediate inspection, inspection forgings size and surface defects; Heat treatment of forgings to eliminate forging stress and improve metal cutting performance; Cleaning, mainly to remove the surface oxide skin; Correction; Inspection, general forgings to go through the appearance and hardness inspection, important forgings also through chemical composition analysis, mechanical properties, residual stress and other tests and non-destructive testing.
We have equipped with the latest testing instruments and testing technology, the use of computer control data processing of modern automatic ultrasonic testing system, the use of a variety of special automatic ultrasonic testing system, to complete the certification of various quality systems.We use computer simulation technology, computer aided process design and virtual technology to improve the process design level and product manufacturing capacity. DATAFOR, GEMARC/AUTOFORGE, DEFORM, LARSTRAN/SHAPE and THERMOCAL were introduced and applied to realize the process control of computer design and hot working.Most of the hydraulic presses of 40MN and above are equipped with 100-400t. M main forging manipulator and 20-40t. M auxiliary manipulator. A considerable number of manipulators are controlled by computer to realize the comprehensive control of forging process, so that the forging accuracy can be controlled within ±3mm.
