To provide a stacking apparatus and a stack manufacturing system having high accuracy and productivity. A stacking apparatus 10 includes: a stage unit 4 on which a material to be stacked 90 is placed; a sandwiching member 11 that is vertically movable with respect to the stage unit 4, and between which and the stage unit 4 the material to be stacked 90 is sandwiched; a press member 13 that is vertically movable with respect to the sandwiching member 11 and presses the material to be stacked 90; and a guide pin 14 that guides a stack 91a pressed and stamped out of the material to be stacked 90 by the press member 13.

When provisionally blanking a lamination sheet by using a punch for provisional blanking and a counter punch, the displacement of pilot holes located around the lamination sheet is minimized. The progressive die machine (1) comprises a pilot hole punch (72), a punch (9) for provisionally punching an iron core laminate (2) from a strip (W) formed with pilot holes (P), a counter punch (31) provided in a lower die assembly (5) and configured to push the iron core laminate (2) against the punch (9), a stripper plate (13) for separating the strip (W) from the provisional blanking punch after a provisional punching, a punch (10) for completely separating the iron core laminate from the strip. At least a part of the stripper plate (13) associated with the provisionally blanking is not in contact with the strip, and at least a part of an outer peripheral part of the provisionally blanked lamination sheet is formed with a connecting portion (79) connected to the strip.

A processing apparatus includes an upper die assembly a lower die assembly and a driving mechanism. The upper die assembly includes a first cutter. The lower die assembly includes a second cutter and a lower die plate. The lower die plate has an upper end portion facing the upper die assembly. The second cutter includes a second cutting edge portion higher than the upper end portion. Further provided is a control method for the processing apparatus, and a heat exchanger.

The invention relates to a die for a punching device. The die comprises a die base body and a workpiece support body, which is provided on the die base body, to support a workpiece to be machined as well as a cutting to length mechanism for cutting a workpiece part of the workpiece to length. The cutting to length mechanism has a cutting to length element and a counter-cutting to length element for cutting to length interaction with the cutting to length element by several cutting to length strokes. The cutting to length element and the counter-cutting to length element can be displaced relative to one another between a cutting to length position, in which the cutting to length element and the counter-cutting to length element interact with one another so as to cut to length, and an open position, in which the cutting to length element and the counter-cutting to length element are spaced apart from one another. Furthermore, the die has a guide mechanism to guide the workpiece part.

An adjustment device of a punching device punches a workpiece on a die so that the workpiece is punched into a predetermined shape. The adjustment device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. The controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.

In manufacturing a laminated iron core by laminating and bonding iron core laminates blanked from a sheet steel strip into a prescribed profile, the adhesive agent can be applied to the iron core laminates in a stable manner without regard to the arrangement and the number of the application spots on each iron core laminate. The metallic die machine (1) is provided with an adhesive agent application unit (12) configured to apply an adhesive agent to a prescribed area of the sheet steel strip (W) corresponding to the iron core laminates (2), and the adhesive agent application unit is provided with a casing (44) defining a plurality of adhesive agent storage chambers (55-57) for storing the adhesive agent before the adhesive agent is applied to the prescribed area. The casing is provided with a plurality of ejection orifices (H1 to H3) each communicating with a corresponding one of the adhesive agent storage chambers and configured to eject the adhesive agent.

Provided is a die trim section with a recess adapted to retain slugs in a stamping process. The recess may be added to existing die inserts via wire EDM, conventional surface grinding or other suitable methods. The recess extends a distance greater than the die trim punch stroke and the cross-sectional area of the recess decreases along the height of the recess.
