Abstract

In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

Abstract

Plate packs are produced from a sheet-like starting product (1), which is cut to form plates, which are stacked to form a plate pack. The plates within the plate stack are joined to one another by a bonding agent. The bonding agent used is a cyanoacrylate adhesive with a high temperature stability rating. It is applied to a wetting layer (14) for the adhesive. The wetting layer (14) is formulated to a pH in a region >7. The cyanoacrylate adhesive with a high temperature stability rating is able to spread on the wetting layer (14) such that effective wetting takes place, thus achieving quick and secure joining of the plates to one another.

Abstract

In a method for manufacturing lamination stacks of controlled height in a tool, starting, material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.

Abstract

The stack of laminations consists of punched laminations (5), which are bonded together by an adhesive agent. The adhesive agent is composed of an adhesive (4) and an initiator (15), which consists of methacrylates, derivative imines and methacrylic esters. The completely cured adhesive bond has long-term resistance when exposed to a temperature of at least over 80° C.

Abstract

The invention relates to a method and a device for influencing the cut and functional face, especially the reduction, during fine blanking of a finished part, for example, a gear, cut out of a metal strip, wherein the metal strip is clamped during closure between an upper part at least comprising a cutting punch and guide plate for the cutting punch and a lower part at least comprising a die plate and ejector and in a first working stage a blank with reduction is cut out of the metal strip. The invention has the task of providing a method and a device for purposefully influencing the cut and functional face, especially the reduction, during the production of finished parts, like gears, making it possible to purposefully influence or totally eliminate the edge reduction, while simultaneously maintaining the functional surfaces and saving material. This task is solved by cutting out the blank with a defined material allowance relative to the contour of the finished part, at least in the area of the reduction, the size of which within the first working stage is adjusted to a stipulated degree to a material volume that fills up, compensates or exceeds the volume deficit occurring due to the reduction to a preset value and by subsequently during a second working stage shifting this material volume in a forming process opposite the cutting direction of the first working stage on the cutting line of the blank to purposefully fill up the developed reduction.

The flat strip is fed into a tool, at least one plate is stamped out of the plate in the tool, the plate is processed into an attachment in multiple processing steps, at first by fine blanking, in a following second step the developed burrs are flattened and then without finishing the attachment is removed from the tool ready for mounting. Attachments with complex geometry can be produced by combined fine blanking and forming operations in such a way, that mountable and burr-free parts with very small tolerances, high accuracy and process safety can be provided at effective costs. Simultaneous forming and fine blanking of the plate is carried out in the first process stage, wherein the plate is completely cut out of the flat strip and the position, form and location of the inner form created by the forming during the complete cutting out is aligned to the outer contour of the plate, and in the second stage, by centering the plate before flattening the burr, which developed during fine blanking at the outer and inner contours, according to its outer contour and simultaneously orienting the plate according to location and form of the shape of the inner form created in the plate in such a way, that the burr at the fine blanked surfaces can be flattened directly in the tool.

Abstract

Lamination packs of a controlled height are produced in that laminations are punched with a tool and glue is applied partially onto at least one of an upper surface and a lower surface of each of the laminations without the application device that applies the glue contacting the laminations. Several of the laminations are then assembled to a lamination pack. Height of the lamination packs is controlled by interrupting the application of glue for certain laminations so that between some of the laminations that are stacked for assembling a lamination pack there is no glue.

Abstract

The invention relates to a method and a tool for producing workpieces with small corner radii in relation to the cutting thickness and with greatly reduced draw-in by precision cutting in a precision cutting tool (3) of a precision cutting machine, in which method the workpiece is clamped between two tool parts consisting of a respective top and bottom cutting die and of a top (10) and a bottom cutting punch (20), and the cutting is effected in interaction with the top (10) and the bottom cutting punch (20). The object of the invention is to improve a method and a tool for producing workpieces in such a way that the precision cutting can also be applied to parts with small corner radii and sharp-edged corners at a greater sheet thickness without restricting the functioning of the parts and while simultaneously ensuring economical advantages. This object is achieved by the workpiece being machined in a one-stage arrangement in at least two successive cutting sequences (A, B) in different cutting directions with the following partial steps: A) cutting out a semifinished product, matched to the workpiece geometry, in a first cutting operation in a vertical working direction with slight draw-in, B) finish cutting of the semifinished product, produced according to step (A), in at least one further cutting operation in a working direction opposed to step (A), wherein the draw-in of partial step (A) is filled again at least in the corner region.
