A method for producing a clamping ring in which pins that protrude in the region of or near a ring contour are formed on the top and bottom surfaces of a flat sheet metal material and after the ring contour is cut out, burrs that are produced during the cutting are removed by a deburring process. Advantages for the machining of the clamping ring are achieved if before a finish cutting by a complete cutting-out of the ring contour that is carried out from the one side of the flat sheet metal material, the ring contour is partially cut out from the other side in the vicinity of or near the pin protruding from this other side.

Disclosed is a method for manufacturing a light-reflection aluminum door frame molding which comprises a multi-coating-applied aluminum material to thereby improve corrosion resistance and reduce costs. A method for manufacturing a light-reflection aluminum door frame molding includes cutting a metallic plate into a predetermined size, performing anodizing on the metallic plate to form an oxidized film on a surface thereof, performing opaque clear coating and transparent coating on the metallic plate to implement light reflection, and performing press molding on the metallic plate to provide the metallic plate in the shape of a door frame molding.

A method for machining includes providing a component or a semifinished part which has a main body with a first surface and with a first surface coating provided on the first surface. The method also includes notching the component or the semifinished part on the first surface coated with the first surface coating. The method also includes severing, perforating or trimming the component or the semifinished part along the notch. At least a part of the first surface coating which is notched in the process is maintained along notch surfaces.

An uncoiling, blanking and forming method includes the steps of: 1) uncoiling a steel coil, wherein a steel strip uncoiled from the steel coil is cleaned and straightened and is fed by a pinch roller to a blanking region; 2) laser blanking, wherein the steel coil enters the blanking region, is cut by a laser cutting head by way of laser blanking to form sheets with a required shape, with waste materials falling down and being conveyed to the outside; 3) outputting the sheets, wherein the sheets pass over a magnetic telescopic belt conveyor, and then carried by means of a manipulator or a robot to a stamping process; 4) stamping forming, wherein the sheets are stamped to form workpieces; and 5) checking, wherein the workpieces are checked and put in storage. The present invention can achieve joining-up in series of a blanking line and a stamping forming line and realize matching therebetween, and can reduce intermediate steps such as stacking, packing, transportation, positioning, unpacking, carrying, and centring of sheets and stamping-formed workpieces, and also can reduce the room required for transfer, simplify the work flow and joins up procedures in series, to directly machine a material coil by laser blanking to form formed parts.

A tool may be used to shape and/or partially press harden a workpiece. In some examples, the tool may comprise a main body having a surface, as well as a heat conducting system containing a thermal medium. The heat conducting system is integrated in the tool in such a way that, for the heating of the surface, a heat radiating from a heat source is conducted by means of the heat conducting system to the surface of the main body. Further, the heat conducting system may comprise a thermal oil or a melt as the thermal medium. The surface of the main body may be configured to face the workpiece during the shaping or partial press hardening of the workpiece.

A method for manufacturing a separator that can effectively prevent warpage is provided. A method for manufacturing a separator according to an embodiment includes disposing a separator material including a flow path forming region between a first upper die and a first lower die, and pressing the separator material using the first upper die and the first lower die to thereby form a first recessed and projected shape in the flow path forming region and form a second recessed and projected shape outside the flow path forming region.

In a suspension support bracket including a bracket body including a suspension attachment portion configured such that a shock absorber of a suspension device of a vehicle is attached to the suspension attachment portion, the bracket body is constructed of a single metal plate, and thickness dimensions of a region of the suspension attachment portion of the bracket body and a periphery of the suspension attachment portion are larger than a thickness dimension of another region adjacent to the region of the suspension attachment portion and periphery of the suspension attachment portion.

A metal plate stamping method is provided for cutting a metal plate, on which a bulging portion is formed through stamping, at a cutting area that is defined in a portion other than the bulging portion. The method includes forming a bead on the opposite side of the cutting area from the bulging portion and crushing the bead prior to the cutting of the metal plate.

Equipment for manufacturing a separator plate for a fuel cell, according to an embodiment of the present disclosure, includes: a first uncoiler uncoiling a first metal strip; a second uncoiler uncoiling a second metal strip; a press receiving the first metal strip and the second metal strip to respectively form patterns thereon; a welding machine overlapping and integrally bonding the first metal strip and the second metal strip, transferred from the press, by a welding process; and a cutter cutting a bonded body of the first metal strip and the second metal strip, transferred from the welding machine, wherein the press, the welding machine, and the cutter are sequentially arranged, and the first metal strip and the second metal strip are passed through the press, the welding machine, and the cutter, while connected to each other, to be processed.

A disc spring which is used by arranging a plurality of the disc springs in an axial direction along a central axis includes an annular body plate portion that has an inner peripheral surface and aa outer peripheral surface which gradually extend toward one side in the axial direction from an outside toward an inside in a radial direction, and a stopper portion that protrudes from the body plate portion in a direction intersecting the inner peripheral surface and the outer peripheral surface of the body plate portion, in which in a case where an axial compression load is applied to a spring member in which a plurality of the disc springs are arranged in the axial direction, the stopper portion abuts another disc spring adjacent in the axial direction or a support member supporting an axial end portion of the spring member, the body plate portion and the stopper portion are integrally formed, and both axial end edges of the stopper portion are positioned inside both axial end edges of the body plate portion in the axial direction.
