Method for operating a fine blanking system
11331711 · 2022-05-17 · ·

A method for operating a fine blanking system comprises at least one fine blanking press having a first press unit, a second press unit, and one or more sensors. The method comprises obtaining parameter data from the one or more sensors for at least one of the first press unit, the second press unit, and another component of the fine blanking system during a first fine blanking process step. Adjustments are determined for control parameters of at least one of the first press unit, the second press unit, and the other component based on the parameter data. The adjustments are applied to the control parameters in a second fine blanking process step subsequent to the first fine blanking process step.

Method for processing steel plate

A method for processing a steel plate capable of removing residual strain at a trim edge thereof without causing overheating in areas of the steel plate other than the trim edge. A method of processing a steel plate includes punching a steel plate and disposing heating electrodes in such a way that a trim edge punched in the punching is positioned between electrode surfaces facing each other and then heating a part of the steel plate including the trim edge.

TOOL AND METHOD FOR PROCESSING PLATE-SHAPED WORKPIECES, IN PARTICULAR METAL SHEETS
20220143666 · 2022-05-12 ·

A tool and method for processing plate-shaped workpieces, such as metal sheets. An upper tool and a lower tool are moved toward one another with a workpiece arranged in between. The upper tool carries a processing tool on a main body opposite a clamping shank. The lower tool has a main body and bearing surface for the workpiece with an opening in the bearing surface. The processing tool of the upper tool has a bending edge and the main body of the lower tool has a counterpart bending edge which is positioned in the opening of the bearing surface. The bearing surface being displaceable relative to the counterpart bending edge such that the counterpart bending edge projects from the opening in the bearing surface.

MANUFACTURING METHOD AND MANUFACTURING DEVICE OF ELEMENT

An element manufacturing method for a transmission belt of a continuously variable transmission having a thick wall portion and a thin wall portion formed by sequentially feeding a material having a strip shape with a uniform thickness to each press position and performing press working on the material at the press position. The method includes, as the press working performed at the press position: a preliminary punching step in which a portion other than a connecting portion is cut off from surrounding material and the cut off portion is punched so as not to overlap with the surrounding material in a plate thickness direction; a crushing step of compressing and crushing a region of the thin walled cut off portion, after the preliminary punching step; and a punching step of punching the cutting off portion into an outer shape corresponding to the element, after the crushing step.
