Beschreibung
Zusammenfassung:	The invention discloses a manufacturing method for a closed-type forged joint. The manufacturing method includes the following steps that first, the closed-type joint is subjected to numerical simulation, and the structure of the closed-type joint is optimally designed; second, a hot forging blank is formed, so that the closed-type joint with a basket lifting hole and a straight hole is obtained; third, the straight hole of the closed-type joint is squeezed so that a taper hole can be manufactured; fourth, the closed-type joint with the taper hole is detected; and fifth, the closed-type joint qualified through detection is modulated and treated. Meanwhile, the invention discloses the closed-type forged joint produced through the technology. The closed-type forged joint produced through the method is high in strength, the internal texture is more compact, the fiber texture of forged pieces can be kept consistent with the appearance of the forged pieces, the effect that parts have a good mechanical property can
