Description

den Bt-uibeiiungssiuicii !»Lochen«. E-'i gleicher Drehzahl und größerem Durchmesser ergibt sich eine größere Vorschubgeschwindigkeit.the Bt-uibeiiungssiuicii! "Punch". E-'i same speed and a larger diameter results in a higher feed rate.

Ist nun keine Stempelreihe in den Bearbeitungsstufen »Lochen« im Eingriff, so wird eine eventuell »angestaute« Schleife durch die größere Vorschubgeschwindigkeit der Trennstufe aufgelöst weil das Band zwischen den Rollen der ersten und /weiten Rollenpaare dieses Werkzeugs mit einem geringem Luftspalt geführt ist.There is now no stamp row in the processing stages "Punching" in engagement, a possibly "jammed" loop is created by the higher feed rate the separation stage dissolved because the tape between the rollers of the first and / wide roller pairs this Tool is guided with a small air gap.

Sind hingegen Stempel im Eingriff, so wird tich der Bandvorschub nach der kleineren Vorschubgeschwindigkeit der Bearbeitungsstufen Lochen einstellen und in der Trcnnstufe ein »Schlupf« zwischen dem Blechband und den Schneideinsätzen (F i g. 13 u. 14) auftreten, d. h. der Schlupf ergibt sich, während der Eingriffszeit der Bearbeitungsstufe »Lochen«, aus der Differenz des Vorschubes der Bearbeitungsstufe »Lochen« plus Bandstreckung minus des Vorschubes der Bearbeitungsstufe »Trennen«. If, on the other hand, punches are engaged, then the tape advance is tich according to the lower advance speed set punching in the processing stages and a »slip« between the sheet metal strip in the opening stage and the cutting inserts (Figs. 13 and 14) occur, i. H. the slip results, during the intervention time of the processing stage "punching", from the difference of the Feed rate of the »punching« processing stage plus strip stretching minus the feed rate of the »severing« processing stage.

Mit den Abstandsrollen (F i g. 6, Teil 4) zwischen den einzelnen Bearbeitungsstufen wird die Lage der von ihnen erzeugten Bearbeitungsbilder im Band zueinander eingestellt.With the spacer rollers (Fig. 6, Part 4) between the individual processing stages, the position of the machining images generated for them are set to one another in the band.

Die Funktion der Abstreiferplatte bei einem gewöhnlichen Stanzwerkzeug übernehmen hier in die Siempelrollen (Fig.4, Teil 1) bzw. in die Trennrollen (Fig. 11, Teil 1) eingesetzte Kunststoffdruckstücke. Eine weitere Lösung hierfür ist der Abstreifer gemäß F i g. 15.The function of the stripper plate in an ordinary punching tool is carried out by the Siempel rollers (Fig. 4, part 1) or in the separating rollers (Fig. 11, Part 1) used plastic pressure pieces. Another solution for this is the scraper according to FIG. 15th

Um die Schneidelemente: Stempel (F i g. 4, Teil 3); Schneidleisten (F i g. 7. Teil 2); Schneideinsätze (F i g. 13 u. 14) nachschleifen zu können werden deren Auflageflächen in ihren Aufnahmen auf einer »Archimedischen Spirale« angeordnet. Zum Nachschleifen wird das kürzeste Schneidelement aus seiner Aufnahme herausgenommen und hierfür das zweitkürzeste eingesetzt. Dies wird mit den anderen fortgeführt, in die Aufnahme des bisher längsten Schneidelementes wird ein neues eingesetzt. Nun können alle Schneidelemenie um den Stufensprung abgeschliffen werden.Around the cutting elements: punch (Fig. 4, part 3); Cutting sticks (Fig. 7th part 2); Cutting inserts (Fig. 13 u. 14) to be able to regrind their contact surfaces in your recordings on an »Archimedean Spiral «arranged. For regrinding, the shortest cutting element is removed from its seat and for this the second shortest is used. This is continued with the others in the recording of the longest cutting element to date, a new one is used. Now all cutting menie can around the Steps are sanded off.

Mit der Ausführung nach F i g. 5 kann für die Stempel besonders hochwertiger und schwer zu bearbeitendet Schneidwerkstoff als einfaches Halbzeug eingesetzt werden; der Grundkörper zur Befestigung in der Aufnahmebohrung besteht aus gewöhnlichem Stahl.

Claims

Patent claims:

1. Roll-forming die for continuous punching and / or punch-bending of strip material with at least 2 processing tools, with each stage processing tools arranged on a pair of rollers and provided approximately the same diameter and speed of the roller pairs are, characterized in that the last pair of rollers generates the tape feed and this by the amount of tape stretching due to processing in the pairs of rollers in front of it is greater than the peripheral speed of the first pair of rollers (s), the band between the engagement of the tools of the first roller pair (s) in the working gap of the or the first pair of rollers (s) can slip freely while these tools are engaged Slippage takes place in the last pair of rollers, and that the Grumirächen the cutting element receiving bores or grooves lie on a spiral around the roller axis.

2. Roll-order cutting tool according to claim I, characterized in that the diameter of the the last pair of rollers are slightly larger than the ones in front and the pairs of rollers for Synchronous coupling of gears with all pairs of rollers has the same number of teeth and thus the same number of teeth Speed, but with the last pair of rollers a higher one due to the shifting of the profile of the gears Pitch circle diameter allows the larger Achsabitand these roles

3. Rollefolneidwerki-eug according to claim 1 or 2, characterized in that adjustable order between the pairs of rollers. . -ncrolls or distance correction rollers are arranged (Fig. 6. Part ♦) -

4. Roll-order cutting tool according to one of the preceding claims, characterized in that that used in the scope of the rollers plastic pressure pieces or spring loaded pins as Wipers are provided (Fig. 4 and II. Part 1) (Fig. 15).

5. Roll-order cutting tool according to one of the preceding claims, characterized in that that for the cutting tools geometrically simply shaped semi-finished products made of conventional cutting material in the form of bushings (Fig. 8) or cutting sticks (Fig. 3. Part 2) are provided, which in corresponding mounting bores or grooves (Fig. 7 and 8) can be used on the circumference of the rollers.

6. Roll-order cutting tool according to one of the preceding claims, characterized in that that the rollers are composed of individual disks (FIG. 4) and the disks have receiving bores incorporated for the stamper (Fig. 5) are and that the punch (part 3 in Fig. 4) are held by cross pins.

7. Roll-order cutting tool according to one of the preceding claims, characterized in that the last pair of rollers with cutting inserts is equipped on carrier disks according to claim 6 (Fig. 9 to 14), the cuts in the longitudinal direction are provided to extend from hole to hole that the band in individual spiked bands is splittable.

The field of application of the invention is punching technology. A roll-to-roll die can be used where previously follow-on dies were used, with which parts are punched from endless tapes or long tapes.

There are already Rollefolgesch.ieidwerkzeuge known (including from DE-PS 9 26 424) as described in the preamble of the main claim.

How such a roll-on cutting tool works is that the lifting and advancing movement of an ordinary punching tool is replaced by the rotational movement of the punch roller (FIG. 4) and the cutting roller (FIG. 7); both rollers rotate at the same speed. Are several for different processing stages Pairs of rollers arranged one behind the other, so there is a possible stretching of the tape at Punch-cutting process the risk that the processing images on the tape of the individual stages will not more can be generated in their desired mutual position. For the drawn tool this would e.g. B. mean that the distance between the holes produced by the first stage "holes" and the holes in the second stage is constantly changing. This is explained by the fact that both pairs of rollers have the same feed speed generate, but the belt leaves the one pair of rollers faster by stretching (similar to rolling) when it is picked up by the second stage. So it would be a constant enlarging belt loops are created between the two pairs of rollers. To the same extent would the Change hole spacing.

The object of the invention is to overcome this difficulty, which is common to all roll-to-roll cutting tools inevitably adheres.

In the case of a tool of the generally known type, the task is achieved by the characterizing features of the main claim solved.

Claim 2 gives a solution for increasing the belt speed in the last Pair of rollers in spite of the same speeds of all pairs of rollers coupled by means of gears.

Claims 3 to 6 indicate advantageous configurations of the general tool shape. while Claim 7 relates to a special tool for the production of spiked bands.

In the drawings is a Roll following tool for the production of spiked ribbons listed. In this are the individuals Processing stages of the follow-on cutting tool handled on pairs of rollers arranged one behind the other been. For the spiked band, these are the processing stages "punching" and "cutting". The processing stage "Punching" (Fig. 2 and 3) was divided into two equal pairs of rollers so as to be sufficiently spaced for the cutting edge (Fig. 2. Part 2) in the Reach the cutting roller (Fig. 7) / u.

In order to be able to generate a perfect stan / image, the separation stage (Fig. 9) is formed so that their The feed rate is somewhat higher than that of the »punching« processing stages. You can do this here in that the gears of the separation stage have the same number of teeth as the gears on the other Machining stages, however, have a slightly larger wheel diameter by shifting the profile (Fig. I). The diameters also become accordingly of the roles (Figs. 11 and 12) from the separating stage somewhat larger than the diameter of the rollers (Figs. 4 and 7) of
