Embodiment Construction

[0023] Such as Figure 1 to Figure 6 as shown,

[0024] A mechanism for adjusting the inclination angle of the main shaft of a rim rolling machine, including a machine body, an upper main shaft module and a lower main shaft module, which are described below:

[0025] The upper main shaft module includes a first eccentric block 11 , a first hinge shaft 12 , a first main shaft 13 and a first incomplete gear 14 .

[0026] The first eccentric block 11 is a cast iron, in the first eccentric block 11 machining two parallel first through holes and second through holes, the first hinge shaft through the first through hole rear front end is installed one The first joint bearing, the first joint bearing 15 is sleeved in the first cylindrical sliding sleeve, the first cylindrical sliding sleeve is sleeved in a shaft hole of the frame, and an end cover is fixed on the outer end of the first cylindrical sliding sleeve , A limit slide slot along the axial direction of the first hinge axis...

Abstract

A mechanism for adjusting the inclination angle of a main shaft of a rim roll forming machine comprises a machine body, an upper main shaft module and a lower main shaft module. The upper main shaft module comprises a first eccentric block, a first hinged shaft, a first main shaft and a first incomplete gear, wherein the front end of the first hinged shaft is movably arranged on the machine body through a first knuckle bearing, the rear end of the first hinged shaft is movably arranged on the machine body, and a self-aligning bearing is arranged between a first eccentric sleeve and the first hinged shaft. The front end of the first main shaft is a cantilever end at which a die is installed, and the back end of the first main shaft is connected with a drive oil motor through a first cardan. The eccentric direction of the first eccentric sleeve and the eccentric direction of a second eccentric sleeve are opposite, so that when one of the two eccentric sleeves is driven to rotate, the first eccentric sleeve and the second eccentric sleeve move face to face or back to back at the same time. Two main shafts link and adjust towards the middle at the same time, and the problems that when only one main shaft is adjusted, the included angle is adjusted, the die changes front and back in a displacement mode, and the front forming face and the back forming face are unmatched are solved.

Description

technical field [0001] The invention relates to the improvement of a local mechanism of a rim rolling machine, in particular to a mechanism for adjusting the inclination angle of a main shaft of a rim rolling machine. Background technique [0002] The rim rolling machine is a kind of equipment that rolls the steel ring to the rim that meets the predetermined requirements. It generally includes two upper and lower main shafts and a guide positioning mechanism. The upper and lower main shafts are installed on the body through bearings, and at the ends of the upper and lower main shafts A rolling die is installed. When working, the upper and lower rolling dies rotate together in the same direction, and the pressure between the upper and lower rolling dies is used to compress the workpiece to deform, thereby rolling the steel ring into a rim blank that conforms to the shape. In this process, since the upper and lower main shafts are cantilever beam structures, it is easy to defo...
