A method for manufacturing a metal element includes performing press processing and punching processing on a band plate-shaped metal element material having a constant cross section by a mold with a main punch in contact with a rear surface of the metal element and a counter punch in contact with the front surface thereof. The main punch or the counter punch has protrusion portions which are in contact with at least a part of the ear portion or the body portion to form a recessed portion, and a bulging portion bulging in the longitudinal direction from the radial direction inner edge of ear portions of the metal element or the radial direction outer edge of a body portion thereof, which is formed by the material extruded from the recessed portion by the protrusion portion.

A method for manufacturing a hot pressed product by heating a sheet material and quenching the sheet material while molding the sheet material includes a hole forming step of forming a pilot hole in the sheet material; a heating step of heating the sheet material in which the pilot hole is formed; and a molding step of forming a burred portion at the pilot hole by using a burring punch included in a die set while molding the sheet material in the die set. The pilot hole has an opening shape in which convex portions and concave portions are alternately arranged. A diameter of a circumscribed circle that is in contact with the convex portions is greater than a punch diameter of the burring punch. A diameter of an inscribed circle that is in contact with the concave portions is less than the punch diameter of the burring punch.

A method of forming a plurality of shaped piece parts from a sheet of material involves arranging a plurality of aligned workpieces into an optimized workpiece pattern, and arranging one or more series of joints that maintains the workpieces in rigid connection and alignment. The joints include one or more particular joints that have an axis of rotation, which permits a first section of the workpieces to be rotated about the axis of rotation with respect to a second set of workpieces to weaken and break the one or more particular joints. The method also involves applying one or more folds across the sheet of material to form one or more pluralities of aligned bends in at least some of the plurality of workpieces. The method further involves breaking the joints to rigidly decouple each of the plurality of shaped workpieces into individual piece parts.

Method of Forming a Balanced Disc with Angled Lip
20210260639 · 2021-08-26 ·

In order to provide a balanced bent lip disc, the applicant routinely had issues with rippling at an outer circumference edge of the lip. Due to the geometries involved in a 3½ inch disc bent to provide an outer lip of ½ inch at 45 degrees, 0.1145 of excess circumference is created thereby providing a ripple effect. The applicant discovered that simultaneously embossing the lip while bending the lip could reduce this rippling effect (and the outer circumference at the edge) by at least 75 if not 90 or 95% of a non-embossed lip bent in the same manner.

Processing device and processing method

A processing device is provided which feeds a long plate body from an upstream side to a downstream side and sequentially carries out a press work including a blanking work to the long plate body. The processing device includes a plurality of stages provided along a feed direction of the long plate body, which has a die that applies the press work to the long plate body and a plurality of lifters provided along the feed direction of the long plate body which have lift-up parts that lift up the long plate body from the die. In the plurality of lifters, clearances by the lift-up parts of the lifters arranged in the downstream side are set to be larger than the clearances by the lift-up parts of the lifters arranged in the upstream side.
