Description
Technical Field
[0001] The present invention relates to the technical field of extrusion molding, and in particular to a continuous extrusion molding device for alloy conductors of new energy vehicles. Background Art
[0002] The battery shell of new energy vehicles is usually formed by extrusion of alloy plates. When the plate is extruded into an upward-opening battery shell, it is not formed in one go, but multiple dies are used to gradually extrude the plate into an upward-opening basin shape. Then the robotic arm moves the basin-shaped part to the next die for extrusion, making it closer to the final shape of the battery shell, and then the robotic arm moves it to the next die for extrusion... This set of continuous extrusion equipment is generally composed of 5 sets of dies. By coordinating the processes, the depth of the alloy plate is increased, while the cross-sectional area is gradually reduced, and its shape gradually forms an upward-opening rectangular shell, thereby completing the production of the plate to the battery shell.
[0003] The existing technology extrudes the sheet material by arranging multiple sets of molds in sequence, and sets a mechanical arm between two molds to move the product in the mold. Some of them use a three-in-one skew feeder to move the product.
