Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] The structure of the stamped and welded leaf spring seat for the inner high-voltage axle housing of the present invention is as figure 1 , figure 2 As shown, including the bottom plate 3, a bent plate 8 is arranged above the joint of the bottom plate 3, and the bent plate 8 and the bottom plate 3 are stamped with bends respectively. The bending of the bottom plate 3 is "n" type, and the bending of the bent plate 8 is "J". ” type, and the bending direction is inconsistent, the bottom plate 3 supports the bent plate 8 and is welded together with the straight side hook plate 4 and the oblique side hook plate 1. The oblique side hook plate 1, the rib plate 2, the straight side hook plate 4 and the reinforcement plate 5 are spliced ​​around the main body to reinforce the main body. The spliced ​​parts are all welded by gas shielded weldin...

Abstract

The invention discloses a press-welding steel plate spring seat for an internal high-pressure axle housing. The press-welding steel plate spring seat comprises a bottom plate, wherein a bending plate is arranged above a connecting position of the bottom plate; the bottom plate is bent into an n shape; the bending plate is bent into an J shape; the bottom plate is used for supporting the bending plate and is connected with a straight side hook plate and a diagonal side hook plate into a whole in a splice welding way; the diagonal side hook plate, the straight side hook plate, a rib plate and a reinforcing plate are spliced to the periphery of a main body to reinforce the main body. The invention also discloses a preparation method of the press-welding steel plate spring seat. The preparation method comprises the steps of respectively bending the bottom plate and the bending plate into the n shape and the J shape by utilizing a 500-T oil press; splicing the bending plate, the reinforcing plate and the bottom plate from top to bottom and fixing the bending plate, the reinforcing plate and the bottom plate through spot welding; then, carrying out tack welding on the diagonal side hook plate, the rib plate and the straight side hook plate along two sides of the bending plate; finally, carrying out tack welding on an upper abrasion reduction module and a middle abrasion reduction module on which thermal treatment modulation are carried out to fix the upper abrasion reduction module and the middle abrasion reduction module. The press-welding steel plate spring seat disclosed by the invention is good in quality, high in accuracy, high in strength and simple in technology.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a stamped and welded steel plate spring seat for an inner high-voltage axle housing, and also relates to a production method for a stamped and welded steel plate spring seat for an inner high-voltage axle housing. Background technique [0002] At present, the leaf spring seat on the automobile axle housing mainly adopts the casting process. Due to the heavy weight of the cast steel leaf spring seat, there are many casting defects and are not easy to control. The loss is serious, and the pollution is serious at the same time. Contents of the invention [0003] The object of the present invention is to provide a stamped and welded leaf spring seat for the inner high voltage axle housing, which has good quality, high precision and high strength. [0004] Another object of the present invention is to provide a method for producing a stamped and welded leaf spring seat ...
