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...

Abstract

The invention provides a manufacturing method of a driving axle housing of a heavy load road roller, which improves the strength and rigidity of the driving axle housing and can be used on a heavy load road roller more than 20 tons; the manufacturing method also improves the material utilization, reduces the weight and reduces the production cost, and simultaneously improves the production efficiency, reduces the rejection rate and makes the process simple and convenient, so that the driving axle housing can be processed easily. The driving axle housing is composed of an axle housing, a support, rib plates, a flange, a bottom cover, axle ends and a welding rivet; both ends of the axle housing are connected with the axle ends symmetrically, the welding rivet is fixed at the connection part of the axle ends and the two ends of the axle housing; the rib plates are arranged at the inner sides of axle ends symmetrically and the support is fixedly connected with the inner sides of the rib plates; the flange is arranged at the middle part of the axle housing and the bottom cover is fixedly connected at one side of the flange. The process method of a road roller driving axle housing comprises sequentially accomplished steps of axle housing pressing, welding, shot blasting, acid cleaning, phosphating, washing, under-coating vanishing, processing, hot pressing of axle end, correcting and welding-on. The driving axle housing provided by the invention has the advantages of simple structure, and prolonged service life, is easy to produce, and is convenient and fast to manufacture.

Description

technical field [0001] The invention relates to a device and a process method of a driving axle housing, in particular to a manufacturing method of a driving axle housing of a heavy-duty road roller. Background technique [0002] At present, as an important part of road construction machinery, road rollers are widely used in earth-rock dam construction, building foundation, roadbed and road construction. According to the compaction principle of the road roller, it can be roughly divided into two categories: static pressure road roller and vibratory road roller. , so that the soil is vibrated. Among them, the large-tonnage single-drum vibratory roller has been widely developed in China in recent years because of its high efficiency, energy saving, and wide range of soil properties. [0003] The heavy-duty single-drum vibratory roller is driven by a wheeled chassis drive axle. The main function of the wheel chassis drive axle is to reduce the speed through the main drive, i...
