Embodiment Construction

[0009] Referring to the accompanying drawings, a half-axis punching and rolling die with a flange includes a die set 8, a punch 5, a connecting die 6, a punch outer sleeve 3 and a pressing plate 2. The punch The die is set on the 7 flanges of the semi-shaft forging and tightened against the flange. The punch and the outer insert of the punch are fitted with a gap and connected by screws. The die is set on the shaft section of the half-shaft forging and the The die sleeve is fixedly connected, and the outer insert sleeve of the punch is connected with the swing head 1 through the pressing plate.

[0010] Preferably, the half-shaft punching and rolling die with a flange also includes a die pad 4, which is arranged on the flange section and the transition part between the flange and the half-shaft forging to protect the half-shaft forging .

[0011] A semi-shaft punching and rolling mold with a flange proposed by the present invention realizes one-time processing and molding of ...

Abstract

The invention discloses a punching and swing grinding die of a half axle with a flange disc. The punching and the swing grinding die of the half axle with the flange disc comprises a die sleeve, a terrace die, a connecting die, a terrace die outer bushing and a pressing board. The terrace die is arranged on the flange disc of a half axle forging and ejecting the flange disc, the terrace die and the terrace die outer bushing are in clearance fit and connected through screws, the connecting die is arranged on the axle body section of the half axle forging and fixedly connected with the die sleeve, and the terrace die outer bushing is connected with a swing head through the pressing board. The punching and swing grinding die of the half axle with the flange disc achieves one-step forming of the half axle with the flange disc, saves working hours and materials, facilitates subsequent processes, shortens the overall machining time and improves the machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a half-axis punching and rolling die with a flange. Background technique [0002] The drive axle is one of the important large assemblies on the motor vehicle, and the half shaft is the key transmission part of the drive axle. The power transmitted by the motor vehicle is transmitted to the axle input flange through the transmission shaft, the axle input flange drives the driving bevel gear to rotate, and the driving bevel gear drives the driven bevel gear to rotate. At this time, the differential shell connected with the driven bevel gear At the same time, the rotation of the differential case drives the rotation of the cross shaft of the differential. The planetary gear is assembled on the cross shaft. At this time, the side gear meshing with the planetary gear of the differential starts to rotate together. The key meshes to realize the synchronous rotation of th...
