Embodiment Construction

[0017] The following examples are only used to illustrate the present invention, but not to limit the protection scope of the present invention.

[0018] figure 1 As shown in , a power battery aluminum shell of the present invention is formed by cold extrusion. The mold is divided into two parts: an upper mold and a lower mold. Tight sleeve 4, clamping nut 5 and fixing bolt 6, the lower mold part includes lower mold 9, cushion head 10, die base 11, die nut 12, 4 clamping blocks 13 and 4 bolts 14, the upper die punches The rod 1 is installed on the front side of the upper die base 2, and the spacer 3 is used to adjust the distance in the middle. The clamping sleeve 4 clamps the upper die punch rod, and the clamp nut 5 clamps the upper die punch rod and installs it on the upper die base. 2, the upper mold base 2 is installed and fixed on the front end of the slider 7 through the fixing bolt 6, and the slider 7 is set on the guide rail 8; the lower mold 9 is installed in the die...

Abstract

The invention discloses a cold extrusion forming die for an aluminum shell of a power battery. The die is divided into two parts: an upper die and a lower die. The upper die part includes an upper die punch, an upper die seat, a spacer, a clamping sleeve, a clamping Nuts and fixing bolts, the lower die part includes a lower die, a head, a die seat, a die nut, a plurality of clamping blocks and a plurality of bolts. The invention also discloses a cold extrusion molding method for the aluminum shell of a power battery. The aluminum billet treated with zinc stearate powder stirring and smearing is one-time cold extrusion into the power battery aluminum shell. A horizontal multi-link toggle cold extrusion press is used to cold-extrude the aluminum billet into the power battery aluminum shell at one time; its production efficiency is high; the grain structure of the aluminum shell is denser, which enhances the toughness, tensile strength, Compressive strength and flexural strength; save energy, save labor, and reduce manufacturing costs.

Description

technical field [0001] The invention relates to a cold extrusion molding die for an aluminum shell of a power battery. [0002] The invention also relates to a cold extrusion molding method for the aluminum casing of the power battery. It belongs to the field of metal forming. Background technique [0003] The power battery aluminum shell is used for the power battery shell of high-speed rail, motor vehicle, lithium battery car, etc. It is a new product in the environmental protection energy industry without emissions. At present, the production method of stamping and forming aluminum shells of power batteries in domestic enterprises is to use general punching machines and hydraulic presses to punch and blank the aluminum sheet and then stretch it in multiple passes (usually 7-8 passes) and temper multiple times to remove stress (usually 3- 4 times), the production process is complicated, the process is long, the energy consumption is high, the production efficiency is low...
