A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including but not limited to oil or lubricant adhesion.

A stamped steel detectable warning tile and method of forming such is described that includes preforming structures in the tile and subsequently coining the structures to form tactile portions to provide satisfactory end results. Further, the tactile portions can be formed in a staggered fashion along a press to distribute tonnage and extend the lifespan of the press, as well as control a curvature of the tile due to the press operations.

A can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

A machine tool for machining planar workpieces includes an upper tool, a lower tool, a machine frame, and a controller. The upper tool is movable with a stroke movement along a stroke axis by a stroke drive device in a direction towards a workpiece and in the opposite direction and positionable with an upper traversing movement along an upper positioning axis by a motor drive assembly. The lower tool is aligned with the upper tool and is positionable with a lower traversing movement along a lower positioning axis by a motor drive assembly. The upper and lower tools are movable in a frame interior of the machine frame. The motor drive assemblies can be controlled by the controller. The upper and lower traversing movements can be controllable independently of each other. The upper tool can be controlled with the upper traversing movement and the stroke movement in a superposed manner.

A planar workpiece machining device has an upper tool and a lower tool that are movable toward each other in a reciprocation direction and in the opposite direction to machine a workpiece arranged therebetween. The upper tool has a clamping shaft, an upper main body, and a tool body arranged opposite the clamping shaft on the main body and having an upper bending edge. The lower tool has a lower main body, on which a counter tool body having a lower bending edge and a counter holder are provided. The lower bending edge is oriented facing the counter holder. The upper bending edge is stationary to the upper main body, and the lower bending edge is stationary to the lower main body. The upper bending edge is associated with an undercut on the tool body and the lower bending edge is associated with an undercut on the counter tool body.

A guided keeper assembly for metal forming dies includes a base having a mounting face and a fastener aperture to mount the base to an associated die shoe, as well as a central guide aperture. A guide pin having a central portion is closely received in the central guide aperture for precisely guiding reciprocal motion between the die pad and the die shoe. The guide pin has an enlarged head at one end which abuts the base to positively limit travel between the die shoe and the die pad, and a shoulder at an opposite end with an alignment mechanism that precisely locates the guide pin on the die pad. A fastener extends through the fastener aperture in the base to securely connect the same with the die shoe. Another fastener securely connects the second end of the guide pin with the die pad.

The present invention relates to a forging method and a forging apparatus, capable of: reducing the amount of tray plates used during the forging of materials by reducing the width from front to back of the tray plates by fixing only the rear of the materials to the tray plates for fixing the materials; and minimizing the amount of materials used, by compression-molding products by fixing, to the tray plates, the materials having a minimum size necessary for the fmal products, the present invention comprising: a press having upper and lower molds; a tray plate supply means for supplying, to the top rear of the lower mold, tray plates to be vertically movable from one side to the other side by a pitch and to be spaced from the upside of the lower mold; a punching unit provided at one side of the upper and lower molds so as to continuously punch material fixing hole parts in the tray plates; a material plate supply means provided at the front of the other side of the punching unit so as to supply material plates by a pitch to under the material fixing hole parts of the tray plates and, at the same time, form penetrating protrusion parts, which penetrate into the material fixing hole parts, on the rear top of the material plate in each pitch, which is moved by a pitch; a cutting and compressive fixing unit provided on the upper and lower molds at the other side of the punching unit so as to cut the material plates, which are inserted into the material fixing hole parts of the tray plates, by a pitch and, at the same time, allow the penetrating protrusion parts formed at the rear of the cut materials to penetrate into the material fixing hole parts, thereby compressively fixing same; and a compression molding unit provided on the upper and lower molds at the other side of the cutting and compressive fixing unit so as to compression-mold the materials being transferred.

A method for manufacturing a press-molded article includes: preparing a patchwork blank in which a thickened portion is formed by welding patchwork to basework; bending only the thickened portion of the patchwork blank; and bending a portion other than the thickened portion in a step different from bending of the thickened portion.
