Abstract

The invention discloses a length-specified machining platform for a formed automobile rear axle shell piece. The length-specified machining platform for the formed automobile rear axle shell piece comprises an upper die frame and a lower die frame, male die insert assemblies are detachably arranged on two sides of the lower portion of the upper die frame, two ends below the upper die frame are detachably provided with adjustable cut-off male die inserts, the two sides above the middle of the lower die frame are provided with a female die insert assembly, two ends of the female die insert assembly are also provided with adjustable cutting-off female die inserts detachably connected with the lower mold frame, the position of the male die insert assemblies corresponds to the position of the female die insert assembly, and the position of the adjustable cut-off male die inserts corresponds to the position of the adjustable cutting-off female die inserts. According to the length-specified machining platform for the formed automobile rear axle shell piece, on the basis of a cold stamping machining-free automobile rear axle forming technique in the prior art, reshaped axle shells are finely trimmed in the length direction, so that the same die is utilized to realize the lengthening of the axle shells with different lengths while long parts left at the two ends are cut off, and each cut forms a neat Y-shaped section which can be used as a welding slope surface during subsequent welding.

Description

technical field [0001] The invention relates to the technical field of manufacturing rear axle shells, and more specifically relates to a processing platform for lengthening and lengthening of automobile rear axle shells after forming. Background technique [0002] refer to Figure 4 As shown, it is a schematic diagram of the structure of the high-precision rear axle shell in the prior art, and its length L is generally required to be ±0.5mm. The current stamping process of the automobile free of machining cold stamping rear axle shell is suitable for batch stability in different rear axle platforms Although this process has many advantages, it inevitably has the defects of simplification of platform products and poor transplantability, which cannot meet the requirements of the automotive market for the same rear axle platform with different lengths and various needs. [0003] For example, the current cold stamping machine processing rear axle stamping process is: shearing→...
