Gear ring forging die for staged forging and forging technology

Abstract

The invention discloses a gear ring forging die for staged forging and a forging technology, and relates to the technical field of gear ring forging dies. The gear ring forging die specifically comprises a main die and a core roller; the main die is composed of sealing rings and a center ring; the sealing rings are arranged above and below the center ring; the center ring is sleeved with a cover die; the cover die is fixed to the center ring through a fixing screw; a welding layer is welded to the outer wall of the cover die; a forming layer is welded to the outer wall of the welding layer; the core roller is arranged on one side of the main die; the core roller is composed of a roller body and a bottom support; the bottom support is fixed to the bottom end of the roller body; a sliding groove is formed in the outer wall of the roller body; the periphery of the roller body is sleeved with a sliding sleeve; the outer wall of the sliding sleeve is sleeved with a first sleeve roller; andthe outer wall of the first sleeve roller is sleeved with a second sleeve roller. According to the gear ring forging die for staged forging and the forging technology, the core roller and the main diecan be freely allocated and are not required to be replaced according to product differences, so that the production cost is reduced, and the applicability of the gear ring forging die is also effectively improved.

Description

technical field [0001] The invention relates to the technical field of ring gear forging dies, in particular to a ring gear forging die for staged forging and a forging process. Background technique [0002] Ring gear forging is a mechanical element with teeth on the wheel rim, which can continuously mesh and transmit motion and power. Gear forging products are mainly used in mining machinery, petrochemical, automobile manufacturing and other industries. There are many methods for processing ring gear forgings. One of them is It is forging processing. Forging processing requires a special mold. Forging processing has the advantages of high efficiency, speed, and precise size. Therefore, forging processing methods are widely used in the production of ring gear forgings. [0003] Ring gear forging molds are generally divided into two parts, the main mold and the core roller. The forging is placed between the main mold and the core roller, and is forged and formed by the main m...

Problems solved by technology

[0004] Most of the existing ring gear forging dies are integrated structures, which do not have detachable structural properties. When they are applied to the processing of ring gear forgings with different structural sizes, they need to be replaced according to product needs, which undoubtedly increases production. Costly, the production efficiency and scope of application of ring gear forging dies are greatly reduced
