Abstract
Description
Technical Field
[0001] The invention relates to a dry powder pressing and molding technology, and in particular to a fully automatic silicon oxide pressing and molding hydraulic press. Background Art
[0002] As a professional battery insulation board for electric vehicles, silicon oxide board has good heat insulation, fire resistance, moisture resistance, and battery collision prevention. The characteristics of silicon oxide powder are ultra-fine particles, light weight, and no fluidity, making it difficult to press and form through a dry powder hydraulic press. Summary of the invention
[0003] Research has found that when a dry powder hydraulic press is used to press silicon oxide plates, there will be a large amount of air (relatively speaking) in the silicon oxide powder because the silicon oxide powder particles are extremely fine, light in weight, and have no fluidity. The silicon oxide plates that need to be pressed have a relatively large pressure area, and the existing exhaust cannot quickly discharge the large amount of air, making it impossible for the silicon oxide plates to be pressed into shape. At the same time, the feeding device equipped with the hydraulic press cannot meet the feeding needs of the silicon oxide powder.
[0004] The technical solution of the present invention: A fully automatic hydraulic press for pressing silicon oxide plates, wherein a pressing die is installed on the hydraulic press, and the pressing die is composed of an upper die, a middle die, and a lower die; the hydraulic press comprises a hydraulic press body and a feeding device installed on the hydraulic press body, and the feeding device comprises a material bin and a material box, and the material bin and the material box are installed on the hydraulic press body; a feeding cylinder is installed on the dry powder machine hydraulic press body, and the feeding cylinder is connected to the material box to drive the material box to move forward and backward; the upper die and / or the lower die are multi-layer structures, and exhaust is arranged on them; the upper die and / or the lower die have seven layers in total, wherein the first layer structure is a stainless steel mesh plate I, the second layer structure is a stainless steel mesh plate II, and the third layer structure is a stainless steel mesh plate II. The layer structure is a stainless steel mesh plate II, the third layer structure is a panel, the fourth layer structure is a template, the fifth layer structure is a transition plate, the sixth layer structure is an adjustment plate, and the seventh layer structure is a bottom plate; the stainless steel mesh plate I, the stainless steel mesh plate II, the panel, the template, the transition plate, and the adjustment plate are all provided with a plurality of holes, and the holes are connected to form exhaust on the upper mold and / or the lower mold; the exhaust effect is good; of course, the holes on the stainless steel mesh plate are not easy to be too large, which will cause the pressed silicon oxide plate to deform, and too small will affect the exhaust effect. Preferably, the holes on the stainless steel mesh plate I are 0.5mm holes and the holes on the stainless steel mesh plate II are 3mm; A stirring shaft is arranged in the material box, on which a stirring blade is installed. The stirring shaft spans across both ends of the material box and is rotatably connected with the material box. One end or both ends of the stirring shaft extend through the material box and are installed with gears. A rack is installed on the main body of the hydraulic press, and the rack is meshed with the gear. The gear moves back and forth with the material box and drives the stirring shaft to rotate by meshing with the rack. The stirring blade rotates with the stirring shaft to stir the powder in the material box.
[0005] The holes on the stainless steel mesh plate I, stainless steel mesh plate II, panel, template, and transition plate are arranged in a matrix, and the adjustment plate is a hollow column. Preferably, the holes on the stainless steel mesh plate I are 0.5 mm holes with a hole spacing of 0.5 mm; the holes on the stainless steel mesh plate II are 3 mm holes with a hole spacing of 3 mm.
[0006] The panel is grooved in the middle and at the four corners, and strong magnets are embedded in the grooves, through which the stainless steel mesh plate I and the stainless steel mesh plate II are adsorbed; the panel and the stainless steel mesh plate II, and the stainless steel mesh plate II and the stainless steel mesh plate I are connected by gluing; the connection is firm, and the stainless steel mesh plate I and the stainless steel mesh plate II are convenient to replace.
[0007] A stirrer is installed in the silo to stir the silicon oxide powder in the silo.
[0008] The invention has the advantages of reasonable design and ingenious conception, and realizes the pressing of silicon oxide plates by using a dry powder pressing and forming hydraulic press, thus filling the market gap. BRIEF DESCRIPTION OF THE DRAWINGS
