Since its establishment, the company has always adhered to the policy of honesty and steady operation, and has the courage to participate in healthy competition in the market and make the rich Kun brand has a good reputation.
At present, the main forging methods at home and abroad are still free forging and die forging. In industrially developed countries, die forging greatly exceeds free forging.
Because die forging has high productivity, high dimensional accuracy of forgings, high material utilization, and the fiber structure is distributed along the contour of the forgings, it has good mechanical properties, high strength, impact resistance and fatigue resistance. If membrane forging and anvil forging can be combined, the economic benefits will be significantly improved. Forging is one of the oldest production technologies invented by mankind and is also one of the important technologies in the machinery manufacturing industry. It includes forging and stamping technologies, as well as related plastic deformation technologies. Forging is the main method and means of metal processing, so the forging process is a development trend. Forging processing can ensure the continuity of the metal fiber structure, so that the fiber structure of the forging is consistent with the shape of the forging, and the metal streamlines are complete, ensuring that the parts have good quality. Mechanical properties and long service life, forgings are heavy load-bearing parts in machines, especially suitable for parts with small structural size and large load or fatigue load. Failure to understand the design of forgings may violate forging principles and forging structure craftsmanship, and may even extend the production cycle of parts. Forging processing can ensure the continuity of the metal fiber structure, so that the fiber structure of the forgings is consistent with the shape of the forgings, and the metal streamlines are complete. , which can ensure that the parts have good mechanical properties and long service life, but increases manufacturing difficulties and costs, and may not be able to forge the parts you designed.
The forging materials are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original states of materials include bar stock, ingot, metal powder and liquid metal. ① Bar: Small and medium-sized forgings use round or square bars as blanks. The grain structure and mechanical properties of the bar are uniform and good, the shape and size are accurate, and the surface quality is good, making it easy to organize mass production. As long as the heating temperature and deformation conditions are reasonably controlled, forgings with excellent performance can be forged without large forging deformation. ②Ingot casting: only used for large forgings. The ingot is an as-cast structure with large columnar crystals and a loose center. Therefore, the columnar crystals must be broken into fine grains through large plastic deformation and loosened and compacted to obtain excellent metal structure and mechanical properties. ③Metal powder: The pressed and sintered powder metallurgy preform can be made into powder forgings by flash-free die forging in a hot state. Forging powder is close to general die forgings. The density of g/cm has good mechanical properties and high precision, which can reduce subsequent cutting processing. The internal structure of powder forgings is uniform without segregation and can be used to manufacture small gears and other workpieces. However, the price of powder is much higher than that of general rods, and its application in production is subject to certain restrictions. ④ Liquid metal: Static pressure is applied to the liquid metal poured in the die cavity, causing it to solidify, crystallize, flow, plastically deform and form under the pressure, so that die forgings with the required shape and performance can be obtained. Liquid metal die forging is a forming method between die casting and die forging. It is especially suitable for complex thin-walled parts that are difficult to form by general die forging.
