Abstract
A pre-tensioned battery shelf includes a base plate configured to support one or more loads, multiple side walls attached to sides of the base plate, multiple fastening panels to reinforce the attachment between the multiple side walls and the base plate and multiple fasteners connected through multiple fastening panels to securely attach the multiple side walls to the base plate. Further, multiple dimples are integrated to the base plate to distribute stress across the base plate, wherein the base plate is pretensioned and inclined, and wherein the multiple side walls are pre-tensioned.
Claims19
A pre-tensioned battery shelf, comprising:
- a base plate configured to support one or more loads;
- a plurality of side walls attached to sides of the base plate;
- a plurality of fastening panels positioned at edges of the plurality of side walls and the base plate;
- a plurality of fasteners connected through the plurality of fastening panels to securely attach the plurality of side walls to the base plate;
- and
- a plurality of dimples integrated to the base plate to distribute stress across the base plate;
- wherein the plurality of fastening panels reinforces an attachment between the plurality of side walls and the base plate;
- wherein the base plate is pre-tensioned and inclined;
- and
- wherein the plurality of side walls are pre-tensioned.
A pressing machine for manufacturing a pre-tensioned battery shelf, comprising:
- a lower die positioned to support a metal sheet during a pressing operation;
- a hydraulic ram connected to an upper die, wherein the upper die is configured to move downward and apply pressure to the metal sheet;
- and
- a control system configured to regulate movement and adjust the pressure of the upper die;
- wherein a convex profile is formed between the upper die and the lower die during the pressing operation,
- wherein the upper die and the lower die are configured to fabricate the metal sheet into a base plate or a plurality of side walls, and
- wherein the metal sheet is pre-tensioned and integrated with a plurality of dimples simultaneously in the pressing operation.
A method for manufacturing a pre-tensioned battery shelf using a pressing machine, the method comprising:
- positioning a metal sheet on a lower die of the pressing machine, the lower die being configured to provide support to the metal sheet during a pressing operation;
- applying pressure during the pressing operation to the metal sheet using an upper die to form a base plate and a plurality of side walls to create a box structure;
- performing pre-tensioning and forming dimples during the pressing operation, wherein the base plate is pre-tensioned and dimpled simultaneously;
- regulating movement and adjusting pressure of the upper die and the lower die applied on the metal sheet using a control system;
- and
- attaching the plurality of side walls to the base plate using a plurality of fastening panels and a plurality of fasteners to construct the pre-tensioned battery shelf;
- wherein the plurality of side walls are pre-tensioned.
