Drive axle housing integrated forming equipment

A technology for forming equipment and driving axles, which is applied in the field of integrated forming equipment for driving axle and axle housings. It can solve the general trend of unsuitable lightweight, lower fatigue resistance of axle housings, and large investment in equipment and tooling, so as to avoid shaft heads. Effects of fracture, strength enhancement, and elimination of welding process

Problems solved by technology

[0002] At present, the drive axle housings on the market mainly include stamping-welding axle housings and cast steel axle housings: 1. The stamping-welding axle housings are made of steel plates and then stamped into a U-shape by a mold, then submerged arc welding butt welding, and then the shaft The head is pressed in from both sides, and then a round of ring welding is performed. The main disadvantages of the press-welded axle housing are: cumbersome process, large investment in equipment and tooling; too many welds on the surface, which is not beautiful; welds have welding defects, and cannot Avoid welding stress and welding deformation, which will reduce the anti-fatigue performance of the axle housing and affect the service life
The main disadvantages of the cast steel axle housing are: the weight is too heavy, which is not suitable for the current general trend of lightweight; Low production efficiency and high scrap rate

Abstract

The invention relates to drive axle housing integrated forming equipment. The drive axle housing integrated forming equipment comprises an axle head forming device, a square pushing device for cold-rolling circular tubes into square tubes, a punching device, a flange hole forming device, a sizing device and a conveying belt which sequentially communicates with the axle head forming device, the square pushing device, the punching device, the flange hole forming device and the sizing device. A drive axle housing forming structure prepared by the equipment is reasonable, the material utilization ratio is high, the rejection rate is low, welding does not exist on the whole, welding stress and defects do not exist, and product performance is stable.

Description

technical field [0001] The invention relates to an integrated molding device for a drive axle housing, which belongs to the technical field of extrusion molding. Background technique [0002] At present, the drive axle housings on the market mainly include stamping-welding axle housings and cast steel axle housings: 1. The stamping-welding axle housings are made of steel plates and then stamped into a U-shape by a mold, then submerged arc welding butt welding, and then the shaft The head is pressed in from both sides, and then a round of ring welding is performed. The main disadvantages of the press-welded axle housing are: cumbersome process, large investment in equipment and tooling; too many welds on the surface, which is not beautiful; welds have welding defects, and cannot Avoiding welding stress and welding deformation will reduce the anti-fatigue performance of the axle housing and affect the service life. The cast-steel axle housing adopts a large-scale sand casting...
