Abstract
The invention discloses a process for stamping a thin-wall battery case by using a joggle die and a joggle die. The process comprises: cutting a blank material to make a spherical blank; mounting the blank on the joggle die; stamping a shell of the battery case by the joggle die; and stamping the blank out from the spherical cavity of the joggle lower female die by using the cylindrical stamp stem to stamp the spherical cavities of a joggle upper female die and a joggle lower female die and forming circular arc-shaped transitional zone at the junction part of the joggle upper female die and the joggle lower female die at the same time. The cylindrical stamp stem is provided with a ring cutting groove. The wall of the shell under the transitional zone is thin and the wall of the shell above the transitional zone is thick, but the inside diameter of the whole shell is consistent; and thus, on the premise of ensuring the whole strength, the materials for producing the lower shell is saved, the material cost is saved and the relative battery holding capacity of the material is increased.
Description
Technical field
The present invention relates to a kind of production technology of battery case, a kind of specifically technology that adopts Production of Stamping Die thin wall battery shell.
Background technology
Traditional die casting comprises common pattern, forging die and mould such as extrusion die, withdrawing pattern etc. that some are special.The present invention has designed a kind of novel stepped diel.
The wall thickness of the battery case that mould commonly used is produced is bigger, is generally the uniform battery case of wall thickness.But through discovering, the opening part of battery case needs inside flanging, and is general bigger to the requirement of strength of structure, and most of housing of battery case does not bear other structural stress except the tension force that bears battery material.So be the thinner structure of wall thickness that the wall thickness of the housing parts of battery case can be designed to the ratio open place, under the condition of the structural strength that guarantees opening part, can satisfy the use needs of battery case in the process of producing.And meanwhile, if having reduced wall thickness also can save and produce the needed consumptive material of battery case, and relative increase the internal capacity of battery case, increased the electric weight of battery.
Summary of the invention
The technology and the ladder die that the purpose of this invention is to provide a kind of ladder die punched thin-wall battery case adopt novel impact style moulding battery case.
The objective of the invention is to be achieved through the following technical solutions:
A kind of technology of ladder die punched thin-wall battery case, blank is cut into circular blank, blank is installed on the ladder die, form the shell of battery case by the ladder die punching press, circular die cavity by columned jumper bar punching press ladder upper cavity die and ladder lower cavity die, blank punching press from the circular die cavity of ladder lower cavity die is come out, has the ring cutting groove on the described columned jumper bar, intersection at ladder upper cavity die and ladder lower cavity die forms the arc transition band simultaneously, the wall thickness of the lower case of intermediate zone is thinner, the upper body wall thickness of intermediate zone is thicker, but the internal diameter of whole housing is identical, so also just under the prerequisite that has guaranteed bulk strength, can save the needed material of production lower case, saved material cost, and the relative battery capacity of material is increased, the arc transition band can solve the structure problem of extending stress band simultaneously.
The ladder die of the punching battery case that above-mentioned technology adopted, comprise the ladder upper cavity die, ladder lower cavity die and jumper bar, ladder upper cavity die and ladder lower cavity die have the butt joint plane, the butt joint plane is the lower surface of ladder upper cavity die and the upper surface of ladder lower cavity die, the correspondence position of ladder upper cavity die and ladder lower cavity die is provided with concentric circular die cavity, circular die cavity is used for punching press to be used, and the aperture of the circular die cavity of ladder upper cavity die is slightly larger than the aperture of the circular die cavity of ladder lower cavity die, the circular die cavity of ladder upper cavity die is used for fixing the blank of battery case, the circular die cavity of ladder lower cavity die is used to support blank and cooperates jumper bar moulding battery case, described jumper bar punching press blank enters in the circular die cavity, the external diameter of jumper bar is less than the aperture of circular die cavity, and the distance of the circular die cavity of jumper bar external diameter and ladder lower cavity die is exactly the thickness of the battery case of the moulding of wanting.
