Hot stamping and warm blanking composite forming technology and mould for ultrahigh-strength steel

Abstract: The invention provides a hot stamping and warm blanking composite forming technology and mould for ultrahigh-strength steel By means of the composite mould, blanking is composited in a hot stamping process, and trimming and punching are performed on sheet metal at a temperature higher than a martensite formation temperature The hot stamping and warm blanking composite forming technology comprises the following processes of putting the sheet metal of the ultrahigh-strength steel heated to achieve complete austenitizing into the composite mould, performing stamping forming and then performing cooling and quenching; heating sheet metal needing blanking locally, keeping a warm state, performing warm blanking after completion of forming, and performing cooling further in a pressure maintaining mode The hot stamping and warm blanking composite forming technology and mould for ultrahigh-strength steel effectively solves the problems of poor quality, low precision, high cost and long period of holes trimmed and punched in the later period of the ultrahigh-strength steel and has great practical significance in production practice

Apparatus and method for manufacture of multilayer metal products

Abstract: Apparatus and method for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, whereby the multilayer metal assembly is stacked vertically. At the location of making shaped parts from the feedstock material, the layers of the z-fold feedstock material may be separated and one or more of the layers treated, textured, embossed, etc., then reassembled into the stack which is fed to the stamping operation, all on a continuous basis. This enables the z-fold feedstock material to be made from smooth metal layers, which increases the density of the material and reduces the volume space required for storage of the z-fold material.

Panel conveying and stacking apparatus

Abstract: This invention relates to an apparatus for conveying stampings from the press and stacking them. The apparatus is provided with automatic means for taking the stamping out of the press, dropping it onto a conveyor, depositing the stamping onto a slide which is automatically actuated to move...

Self=stamping riveting machine for overlapping sheet metal components

Abstract: The machine uses a hollow rivet, engaged by a punch, a die whose cavity (10) contains a profiled pin (5) for deforming the sheet metal components. The component, facing the die, is thicker. The pin also expands the hollow rivet shaft (16). The components are held by a holder (5). The edge, bounding the die cavity, forms a vertical cutting rim (12), entering the thicker component (2) up to a preset depth during compression through the holder. During the riveting the hollow rivet shaft is firmly secured by deformation of the incised component on the profiled pin.

Method for manufacturing press-molded article and press molding equipment

Abstract: A method for press-molding a thin steel plate using a press molding mold and manufacturing a molded article, wherein the thin steel plate is heated to a temperature equal to or higher than the Ac1 transformation point, subsequently cooled to a temperature equal to or less than 600°C, and then molded using the mold. Molding is completed at a temperature equal to or higher than the martensite start temperature (Ms), whereupon the steel sheet is released from the mold and tempered, whereby a press-molded article is productively manufactured, the article having excellent formability to the extent of being suitable for deep drawing.
