Description

The invention relates to a punching device for punching materials, and it particularly concerns one Construction of a punching or stamping unit that is used suitable for every punching process is »by means of which a sentence of openings should be created, which are at very small distances from each other in several Heihe, both in lateral Rows as well as in longitudinal rows, are arranged, it is possible to punch all openings at the same time, and wherein it also enables the invention to prevent deformation of the material between the openings

A main object of the invention is to provide a stamp unit to provide, in which the various punches are arranged in transverse and longitudinal rows, and in such a way that it is possible is to remove or install every row of punches or even a single punch without the need for the Arrangement at other rows of stamps or any other To change stamps within the relevant row or

to dismantle the unit. * - t40cJ

Furthermore, the invention sJöit a stamp unit in which the punches are arranged in an odd number of transverse and / or longitudinal rows, it being possible to use the whole to expand an odd number of punches without disassembling any other legs of the punches or removing them from their positions bring, and a single stamp can be removed from the odd rows of stamps without the need is to relocate other stamps in the relevant series or expand

The invention also provides a combination of punches arranged in rows and spacers for the punches such that the means for securing the spacers in the stamp unit also serve to set rows of stamps in the stamp unit at intervals so that It is possible to expand one or more punches without changing the position of the other punches.

A special feature of the invention is that ' Spacers are provided which are suitable for the lateral Define the distances between the punches and the punches, either in individual rows or in pairs associated rows are arranged, which are displaceable during assembly, to clamp} these means are on the means for holding the spacers and the punches in their operating position within the punch unit arranged and designed so that selected stamps in a row are removed or replaced without affecting the location of the

The holding blocks 15 and the holding pieces 10 are through rectangular wedges 17 »which are firmly built into slots in the support plate are held in flux with each other and with the support plate releasably connected. Lateral holding blocks 18 separated by a distance are located between the front holding blocks 15 provided that are at right angles to the holding blocks 15 extend both sides of the stamp assembly if an even number There is a number of rows of dies assigned to one another in pairs Wedges 19 held in place in the presence of a even number of rows detachably built into the support plate are. If there is an odd number of stamps, the wedge adjacent to this row will be explained below Reasons omitted. The lateral holding pieces 18 form a vertical abutment for the outermost rows of stamps and Abstandsstückη and serve to oppose these parts in plunge to hold the dovetail-shaped wedge. If a stamp is to be removed from one of the outermost rows, the Screws for fastening the lateral retaining blocks rotated around the relevant lateral retaining block opposite the support plate to move downward thus relieving the pressure that is in between the lateral retaining block and the bevel of the stamp comes into effect, so as to the dovetail-shaped in question Relieve the wedge and the corresponding spacer. If the the lateral retaining block opposite the support plate is loosened}, any punch in the outermost row can be removed, without changing the position of any other die within this row.

Spacers pulled out and from the dovetail-shaped one Wedge removed

The lateral holding pieces and the front holding blocks are connected to the support plate by suitable SolirauiDen, and they together form an Eahmeia with precisely defined internal dimensions, which encloses the outer edges of the I-shaped spacers and the stamps in order to hold these parts firmly in their position and in this way to ensure, that the openings punched into the material to be processed are exactly in the right position «Λ _;

According to Jig »1, ² and 11, a half dovetail wedge 20 is provided which is detachably built into a slot in the support plate. This wedge is intended for a single or odd series of punches. A spacer 21 is assigned to each punch. This spacer has a bevel 22j which corresponds to the bevel of the punch and the dovetail-shaped wedge | Furthermore, a tab 23 is provided as a clearance »A recess 24 in the spacer corresponds to the width and depth of the punch. If the punch is arranged in the recess of the spacer, the side surface 25 of the spacer is aligned with the side surface of the punch 26. An unde 27 projects a very small amount beyond the edge 36 of the spacer. The support rod attached to the support plate wedges the punch and spacer securely with the half dovetail wedge. With this construction it is not necessary to provide a lateral holding block in order to hold the last row of punches securely in their operating position.

According to FIG. 7, the die comprises a support plate 28 with an opening 29, via which the cut-off pieces after punching be delivered. 13 are formed in a known manner Die steel parts 30 processed so that they are used for Cross-sectional shape of the punch fit that in the present case have a rectangular cross-sectional shape, as can be seen from Fig. results where the component 30 shown has a transverse main body 31 with ribs 32 spaced apart. The components 30 are attached to the support plate 28 so that their recesses are in alignment with the stamps · The transverse one Main body each of a component 30 is in contact with the Hipping the adjacent component arranged so that rectangular Cutting edges are created that are aligned with the stamp. In the case of punches with irregular or rounded cross-sectional shapes, the die steel parts 33 according to FIG. 16 are on both Sides of a transverse main body 34 with butts 37 and Recesses 35 provided, the cross-sectional shape of the stamp be machined appropriately. The ribs of these die steels are brought into mutual abutment around the die openings and to create the associated cutting edges.

In order to assemble the stamp unit, the rectangular wedges 17 and 19 are built into the support plate 1. Then will the front and side retaining blocks in the correct one Distance from each other attached to the support plate. On that are the paired stamps together with the associated Spacers on the swallowtail wedges postponed, which are movably connected to the support plate, until the relevant row of punches has the required number

An outer or odd number of stamps will be produced by installing only a single punch in the recess of the spacer * The punch and the spacer will be dovetailed on the half described Wedge arranged. A retaining block is attached to the !

If the retaining block is removed, every stamp of the odd-numbered row will be removed, without that it is necessary to determine the position of any other punch within the relevant row or within other rows of changing stamps of the unit.
