Horizontal forging equipment manufacturers tell you that the common die forging method has obvious disadvantages, such as: forging surface heating oxidation, decarburization; low dimensional accuracy, poor surface finish; large machining allowance, low material utilization rate, etc. Horizontal forging equipment manufacturers tell you that precision die forging can obtain forgings with better surface quality, smaller machining allowance (even without cutting) and higher dimensional accuracy; it can significantly improve material utilization, and the distribution of metal streamlines is more reasonable. Improve the bearing capacity of parts.
Horizontal forging equipment manufacturers tell you that especially for those small and medium-sized parts that are expensive in material, large in production batch, complex in shape, and difficult to cut, the precision die forging method is used to produce, and the technical and economic effects are very significant. The precision die forging method can show superiority in economic batches above 2000 pieces. Precision die forging is one of the development directions of modern die forging technology.
At present, the dimensional accuracy that ordinary die forgings can achieve is about ±0.5mm, and the surface roughness is about R. -12.5um, while the general precision of precision die forgings is ±(0.10~0.25)mm, the higher precision is ±(0.05~0.10)mm, and the surface roughness can reach R. -0.8~3.2um. For example, precision die-forged bevel gears can reach ITl0 level, and the tooth shape no longer needs to be cut; precision die-forged blades can reach ±0.05mm in outline dimension accuracy and ±0.06mm in thickness dimension accuracy.
For the same part, the shape of precision forgings is more complicated than that of ordinary die forgings, and the dimensions such as wall thickness and rib width are smaller than ordinary die forgings, which are already close to the shape of the parts, and generally no or less machining allowance is left. Therefore, whether it is upsetting, pressing or extrusion, the deformation resistance will increase, and the mold strength may not meet the requirements. Some measures to reduce the deformation resistance are required, such as local deformation process or isothermal die forging process, etc. . Horizontal forging equipment manufacturers tell you that due to the high dimensional accuracy and surface quality of precision die forgings, sometimes it is necessary to add a finishing process after precision forging.
