Abstract:
A method of shot peening according to the present invention includes: placing a jig having an appropriate dimension at one face side of a stamped workpiece; and performing shot peening on another face side of the workpiece in a state where the jig is placed at the one face side of the workpiece, and conforming the workpiece to the jig. At this time, the shot peening may be performed in such a way that residual stresses in the inner side and the outer side of the curved part of the workpiece will become compressive stresses.
Abstract:
The invention relates to a multi-chamber with ultra-high-pressure or hydraulic motor compressors or motor pumps for compressing gas or liquid at ultra-high pressure, formed by several different-sized concentric chambers, wherein each chamber contains smaller chambers, there being installed between the chambers motors or pumps that enable fluid to be introduced into the inner chambers at increasingly greater pressure.
Abstract:
A bulge forming apparatus including a valve, and a forming die connected to the valve, the forming die including a forming chamber, the forming chamber being configured to receive a blank part and having a working surface, a seal disposed between the working surface and the blank part such that a sealed volume is formed between the blank part and the working surface, and a passage disposed through the forming die such that one end of the passage is open to the sealed volume and another end of the passage is coupled to the valve.
Abstract:
An electrohydraulic forming (EHF) tool and a method of forming a sheet metal blank in an EHF operation. The tool may include a pair of electrodes and may be filled with a liquid. A high voltage discharge may be produced between the electrodes in a manner that induces a shockwave within the fluid. The shockwave may produce sufficient force within the liquid to form the blank against a die.
Abstract:
Method of plastically deforming a body of malleable solid material between male and female dies which are forcible pressed together. The material is subjected to repeated identical pressing cycles; in each pressing cycle the force between the dies is concentrated consecutively on separate sections of the surface of the material being deformed. The body may be directly or indirectly extruded into an elongated shape from a location between the male and female dies which is disposed nearest the section of the surface of the material being deformed in each pressing cycle, or it may be deformed between the dies without any appreciable portion thereof escaping from between the dies.
Abstract:
An energy transfer cooking device accessory is described which includes a plastically deformed metal sheet (and a transformer-like power transfer unit which has a primary circuit and a secondary circuit. The plastically deformed metal sheet is arranged between said primary circuit and said secondary circuit. Simultaneously said plastically deformed metal sheet forms a magnetically permeable coupling point for said primary circuit and said secondary circuit, so that a magnetic flux from said primary circuit to said secondary circuit via said plastically deformed metal sheet is guaranteed. Furthermore, a method of manufacturing an energy transfer cooking device accessory and a cooking device are described.
Abstract:
The spark plug gapping tool comprises a clamp that provides a spark plug holder on a lower arm that is vertically aligned with a threaded shaft and a pressing foot on an upper arm. An inverted spark plug may be installed into the spark plug gapping tool from the bottom side of the lower arm. A mounting clip on the clamp allows a gap gauge to be removably coupled to the clamp and the gap gauge provides a calibrated arm of a specific thickness, which the spark plug gap is to match. A handle on the threaded shaft allows the threaded shaft to be turned, causing the threaded shaft to move up and down within a threaded shaft hole. Downward movement of the pressing foot against an electrode of the spark plug bends the electrode and sets the spark plug gap.

Abstract:
A forming process of sheet materials that comprises the following phases is disclosed:—application of a layer of glue (4) that expands in contact with air on a base support (2) of a die (1),—positioning of sheet material (6) on the layer of glue (4),—closing of the die (1) by means of a matrix (3) provided with at least one cavity (31, 31′), for a time sufficient for the glue (4) to expand, in such a way that the shape of the matrix (3) is formed on the sheet material (6), and—opening of die and removal of formed part.
