Progressive die for machining shell of automobile starting motor

Abstract

The invention discloses a progressive die for machining a shell of an automobile starting motor. The progressive die comprises an upper die and a lower die, wherein a material conveying belt is arranged between the upper die and the lower die; a material belt punching station, an H-shaped groove cutting station, a two-side cutting station, a burr pressing station, a first pre-bending station, a second pre-bending station, a third pre-bending station, a first idle station, a second idle station, a first circle-rolling station, a first circle-rolling and vertical reshaping station, a circle-rolling and horizontal reshaping station, a second circle-rolling and vertical reshaping station, and a cutting separation station are sequentially arranged on the material conveying belt from front to back. After adopting said structure, the progressive die has the beneficial effects of being convenient to operate, and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mold production and processing, and in particular relates to a progressive die used for processing automobile starter casings. Background technique [0002] The automobile starter casing is a metal cylindrical thin-walled part, and its dimensional accuracy is required to be high. In the prior art, the processing method generally used for the casing is to complete the rolling and forming operation of the flat thin plate through multiple processes, such as trimming, deburring, pre-bending, rolling, etc. The existing problems are the required There are many processes, each process needs to be transported, and the labor cost is high. [0003] Progressive die (also called continuous die) is composed of multiple stations, and each station is connected in sequence to complete different processing, and a series of different stamping processes are completed in one stroke of the punching machine. After a stroke i...
