An embossing seal has a base, a die assembly disposed in the base, a driven shaft assembly movably disposed in the base, and a pressing handle pivotally disposed on the base for driving the driven shaft assembly. The driven shaft assembly has a lower shaft, an upper shaft, a cushion spring, and a restoring spring. The lower shaft is movably disposed in a shaft tube of the base. The upper shaft is movably disposed in the lower shaft. The cushion spring and the restoring spring are coaxially disposed around the upper shaft. Two ends of the cushion spring respectively abut against the upper shaft and the lower shaft. Two ends of the restoring spring respectively abut against the upper shaft and the shaft tube. Structure of the base and structure of the driven shaft assembly are simplified. The embossing seal is restored accurately and quickly.

A craftwork accessory may provide a portable and/or easy-to-use tool to help users accurately and repeatedly apply stamp impressions and the like to items such as cardstock. The accessory may include a base portion, one or more elevated side portions and cover portion. The side portions may define a workspace for arranging the item. The cover portion may be movably attached to the base portion or a side portion, for example, by one or more hinges. In operation, the item and stamp may be aligned in the workspace and the cover portion may be pressed onto the stamp to stick the stamp to the cover portion. The cover may then be opened, the stamp may be inked, and the cover portion may be closed and pressed onto the item to stamp the item. The accessory may include alignment indicia on the base portion, side portions and/or cover portion to facilitate placement of the item and/or stamp. The accessory may also include fastening mechanisms, such as magnetic elements, to facilitate placement of the item and/or stamp.

An embossing apparatus which forms an emboss pattern on a sheet-type workpiece using a template sheet with the emboss pattern cut out therefrom, the embossing apparatus comprising: a mounting unit on which both a cutter member for cutting and an embossing pen for embossing are mounted simultaneously or one of the cutter member and the embossing pen is mounted alternatively; a holding member configured to hold the template sheet and the workpiece; a transfer mechanism configured to move the holding member and the mounting unit relative to each other; and a controller configured to control the transfer mechanism, the controller being configured to control the embossing apparatus to: specify the emboss pattern, cut the specified emboss pattern out of the template sheet held by the holding member using the cutter member mounted on the mounting unit by controlling the transfer mechanism, and press part of the workpiece which corresponds to a cutting region cut out, using the embossing pen mounted on the mounting unit by controlling the transfer mechanism, the workpiece being placed on the template sheet held by the holding member.

A stamping press for stamping a round blank. A ram movable in a stroke direction and in an opposite return stroke direction carries a first stamping tool. A second stamping tool and a stamping ring are supported on a press framework. The stamping tools and a stamping opening formed by the stamping ring are aligned along a working axis. An ejector device serves to eject a stamped round blank from the ring opening. It comprises an ejector pin supported on an actuating device that is movably coupled with the ram. During a return stroke of the ram the ejector pin can apply a force on the second stamping tool in order to press the round blank out of the stamping ring. In a ram movement in the stroke direction the actuating device departs from the second stamping tool and no ejector pin force is applied on the second stamping tool.

The present disclosure discloses a method for improving fatigue strength of a workpiece (100). The method comprises positioning the workpiece (100) in a punch and die assembly (102). Operating the punch and die assembly (102) one or more times to imprint surface features (2) on a portion of a surface of the workpiece (100), wherein the surface features (2) induces compressive residual stresses at a sub-surface level of the workpiece (100), and improves the fatigue strength of the workpiece (100).

A plastic component is provided that leads to an initial friction reduction with a friction partner. At least part of the surface of the plastic component, which interacts with a surface of a friction partner, is provided with a plurality of structures. The structures are composed of at least one structure type. Between two adjacent structure types, a distance is formed in the range of 10 microns to 1 mm. A width of the structure types is in the range of 10 microns to 100 microns. A height or depth of the structure types is in the range from 1 micron to 100 microns.
