Embodiment 1
[0029] As shown in the figure, a device for driving the axle housing of a road roller is composed of: the axle housing 1, the support 2, the rib plate 3, the flange 4, the bottom cover 5, the shaft head 6, and the welding rivet 7; the axle housing 1 The two ends are symmetrically connected to the shaft head 6, and the joints between the shaft head 6 and the two ends of the axle housing 1 are fixed with welding rivets 7; A flange 4 is arranged in the middle, and one side of the flange 4 is fixedly connected to the bottom cover 5 .
[0030] The material of the axle housing 1 is 16Mn plate-35Mn plate.
Embodiment 2
[0032] A process method for a drive axle housing of a road roller, which is completed in sequence by pressing the axle housing, welding, shot blasting, pickling, phosphating, water washing, priming, processing, hot-pressing the shaft head, calibration, and welding. The specific process method Proceed as follows:
[0033] Axle case pressing: make molds for pressing the main parts and bottom cover of the axle case. The pressing material of the axle case 1 is 16Mn-35Mn plate with good strength and plasticity. The yield strength of this kind of steel plate can reach 245MPa-335MPa. Normalizing treatment in the heating furnace, the normalizing temperature is 920-870 degrees, one is to eliminate internal stress, and the other is to improve the ductility of the steel plate material during pressing, and it is easy to form;
[0034] Welding: All parts are welded firmly during welding, and there must be no defects such as missing welds, virtual welds, pores, slag inclusions, etc. After w...
