Definitions

• the invention relates to a device for punching, embossing and / or shaping flat elements with a base body with a table and support for the flat element and with a base plate carrying a tool stamp, which with the aid of a drive for performing the machining process on the support in a processing station for the engagement of the tool stamp with the support and away from the support.
• Such devices are used to punch or deform flat semi-finished products such as sheets, strips and blanks in a continuous process.
• These sheets, strips, plates or blanks, called flat elements can consist of different materials, for example cardboard, laminated cardboard material, multilayer material, sheet metal.
• Previously known devices similar to the type mentioned at the outset are provided with a direct hydraulic or pneumatic drive with a cylinder acting on a punching tool.
• the object of the invention is therefore to provide a device of the type mentioned at the outset, with which a large number of very short, high-precision punching strokes in succession are possible for introducing punch holes or embossings.
• a device of the type mentioned at the outset with which a large number of very short, high-precision punching strokes in succession are possible for introducing punch holes or embossings.
• fast moving flat elements short downtimes and thus short cycle times, and possibly even short machining strokes, are to be achieved.
• transmission means are coupled between the drive and the base plate, which transfer the base plate from a rest position, in which the tool stamp is disengaged from the support, essentially without pressure build-up until shortly before the machining position Move a short distance into the machining position while generating a high pressure between the base plate and the flat element and move the base plate back into the rest position when the drive continues to operate over areas essentially without pressure build-up.
• holes can be punched and / or embossed in flat semi-finished products.
• the flat semi-finished products are generally referred to here as flat elements.
• the invention is based on the basic idea of driving the tool stamp attached to the base plate in accordance with a specific movement pattern. This is ultimately about the movement of the tool stamp towards or away from the support which holds the flat element. In the case of punching, a hole can be provided in the support, so that the tool stamp punches through the flat element into this hole in the support. Similar considerations apply to embossing.
• the movement pattern itself should follow the principle of moving the tool stamp (and thus the base plate) towards or away from the machining position without substantial pressure build-up, with a higher movement speed being provided here. If, on the other hand, the tool stamp arrives in the machining position, the movement should only take place over a short distance, but with the generation of high pressure.
• This movement pattern is achieved via an intermediate transmission medium between the drive and the base plate.
• the tool stamp is advantageously kept absolutely parallel to the plane of the flat element over the entire cutting depth or embossing depth in this processing. According to the invention, this advantageously achieves a flat, smooth, sliding and non-jerky course of force. With the invention, those impacts that occur in conventional devices when the full punching force is applied in the linear direction can be avoided.
• the invention provides that the axis of the drive is perpendicular to the axis of the tool stamp; whereas in another embodiment the axis of the drive is parallel to the axis of the tool stamp.
• the drive can be a pressure sensor with cylinder and piston, the piston movement of which in one embodiment runs parallel to the conveying direction of the flat element. Since the axis of the tool stamp is arranged perpendicular to the plane of the flat element, the drive axis is then perpendicular to the axis of the tool stamp.
• the drive is a motor, the axis of rotation of which is parallel to that of the tool stamp; in a special embodiment, the axes even coincide.
• the transmission means have at least one rotary lever which can be pivoted about a fixed pivot point. Such a structure is robust and precise.
• Another preferred embodiment, in which the axis of the drive is perpendicular to the axis of the tool stamp, is characterized in that the linear direction of movement of the base plate is predetermined by a column guide acting between the base body and the base plate and that the drive is in its perpendicular to it Axis (of the drive) has linearly oscillating drive means.
• Such an oscillating drive means can be, for example, a pneumatic or hydraulic cylinder with a reciprocating piston.
• the piston rod can be seen as such a linear, oscillating drive means, through which one can think the axis of the drive is laid.
• the axis of the tool stamp then runs perpendicular to this.
• the column guide enables precise angular holding and exact machining, for example punching or embossing.
• Such an embodiment is further developed according to the invention in that a long rotary lever is pivotable about a pivot point fixed to the base body and is coupled at one end via a toggle joint to one end of a short pivot lever, the other end of which is coupled to the base plate via a toggle lever bearing ,
• This mechanical structure provides a dead center in a certain position of the long rotary lever and the short pivot lever, and this results in the greatest force effects in the vicinity of this dead center, taking into account the basic idea mentioned above.
• this is achieved by the long path of the linearly oscillating drive means, with the advantage of a short path of the machining tool, for example tool stamps.
• the drive can have a pneumatic cylinder or a hydraulic cylinder.
• the long rotary lever, coupled with the short swivel lever can be seen as a kinematic system, which works in such a way that the base plate is a machining operation, for example, both in the direction of rotation of the long rotary lever in the counterclockwise direction and in the clockwise direction Punching process.
• the principle according to the invention can be clearly realized, namely that the tool stamp is first brought close to the flat element with a large and rapid stroke and low force and then the machining is carried out with a short distance and great force; after which, in turn, the tool stamp is removed or moved away from the flat element with a large and rapid stroke and low force.
• At least one roller is rotatably attached to the base plate, which roller is guided against at least one curve, which has a course at least at one point with a component parallel to the axis of the tool stamp. If the curve had no location with such a component parallel to the axis of the tool stamp, the roller running against the curve could not move the roller or the base plate connected to it when the curve was moved relative to the roller. If a short and powerful stroke in the direction of the axis of the tool stamp is desired to carry out the principle according to the invention, then the component mentioned should be provided parallel to the tool axis at the relevant point on the curve.
• the curve mentioned can be provided on an oscillating or rotating machine part which is stationary or movable, provided that only a relative movement between the roller and the curve is possible.
• the curve is provided as a transmission means on the circumference of a rotatably driven cylinder.
• the curve can be incorporated in the form of a groove.

• Finding the cylinder also provided with a coaxially attached pinion, which is driven by meshing with an oscillating rack.
• Another embodiment is characterized in that the curve is provided on the rotary lever.

• a further advantageous embodiment of the invention is characterized in that the axis of the rotary lever is perpendicular to the axis of the tool stamp, which can be moved in translation and rotation relative to the rotary lever via the base plate.
• the rotary lever is a carrier of the tool stamp, possibly also the carrier of two tool stamps.
