Description
Technical Field
The invention relates to an integral lithium battery explosion-proof cover plate stamping die, in particular to a male die for stamping and forming an easily-broken groove on an explosion-proof aluminum shell cover plate of a power battery.
Background
With the rapid development of battery technology, the use of explosion-proof aluminum cases is now a requirement of the battery industry. The prior explosion-proof aluminum shell mainly comprises a cover plate film and a pressing breakable groove. Because the cover plate film pasting mode is to weld or bond the film, the application and popularization of the cover plate film pasting mode are restricted to a certain extent due to high cost and poor processability; the cover plate is used for pressing the easily-broken groove, and the groove with a certain shape and depth is punched on the battery sealing upper cover by adopting a die so as to achieve the aim of pressure relief. The manufacturing is relatively easy, the cost is low, no trouble is added to the battery manufacturing process, and the battery is widely applied at home and abroad. However, in order to ensure the safety of the lithium battery, the detonation pressure is generally designed to have a limited pressure range, and when the pressure born by the breakable groove exceeds the specified pressure, the breakable groove breaks, so that the explosion-proof effect is achieved, but because the components and the process of producing aluminum plates by each enterprise are different, the strength performance difference can occur even for each roll of aluminum plate produced by the same enterprise, and therefore, the thinnest thickness of the breakable groove is generally required to be adjusted in time according to the material strength during production, so that the explosion-proof effect can be achieved.
Disclosure of Invention
In order to solve the problem of strength difference of each roll of aluminum plates, the thinnest thickness of the easily-broken groove is required to be adjusted in time during production according to the strength performance of materials, and an explosion-proof effect is achieved.
In order to achieve the above purpose, the technical scheme of the invention is as follows: a terrace die and subassembly that is used for breakable recess on integral lithium cell explosion-proof apron of punching press, includes terrace die, rotatory worm wheel, worm, micro motor, computer, worm one end is installed in the fixing base, and micro motor is connected to the other end, and rotatory worm wheel is connected in the worm meshing, and rotatory worm wheel passes through screw rod and nut connection terrace die, and micro motor connection computer, computer control micro motor drive worm drive rotatory worm wheel and screw rod are rotatory, and the screw rod passes through the nut and drives the terrace die and reciprocate, realizes the fine setting to the terrace die punching press height of breakable recess.
Further, the male die is composed of three parts, wherein the lower part is a cross-shaped part, the middle part is a square body, the upper part is a cylinder, and a connecting nut is fixed in the cylinder.
Further, the center of the rotary worm wheel is fixedly connected with a screw rod, and the screw rod is screwed with a nut in a cylinder at the upper part of the male die.
Further, the worm is connected with the miniature motor through a coupling.
Further, the computer receives the thinnest thickness data of the breakable groove input by a user, and the number of weeks required by the running of the micro motor is calculated through processing.
The beneficial effects of the invention are as follows:
the male die and the assembly for stamping the easily-broken grooves on the explosion-proof aluminum shell cover plate of the power battery mainly solve the technical problem that the thinnest thickness of each roll of aluminum plate can be adjusted in time during production according to the strength performance of materials through the fine adjustment device, and the fine adjustment of the stamping height of the male die of the easily-broken grooves can be realized.
