Abstract

An impact head (1) of the punch is of such a length as to allow positional adjustment of the punch assembly (6) within a punch guide (5). A tube (3) houses the upper part of the punch, and includes a threaded portion on its external surface which receives a nut (4) connecting it to the guide. The nut locks the tube against the guide in a selected relative position. The internal surface of the guide is threaded to cooperate with the external surface of the tube. The upper and lower parts of the punch are shaped to allow maximum sharpening. ADVANTAGE - Allows adjustment of punch for loss of length due to sharpening, extending working life.

Description

- Outillages de poinçonnage sur commande numerique type "HAMADA" "FINN-POWER" (marque déposées) prévu pour le poinçonnage des tôles.- Punching tools on numerical control type "HAMADA" "FINN-POWER" (registered trademark) intended for punching sheets.

- Problème à rèsoudre : augmenter le nombre, les possibilités d'affûtages pour diminuer la consoniration et le coût des poinçons.- Problem to solve: increase the number, the possibilities of sharpening to reduce the consonance and the cost of the punches.

- I1 existe la solution d'ajouter une rondelle (cale d'affûtage) entre le poinçon et sa butée guide ressort pour maintenir le poinçon en butée.- There is a solution to add a washer (sharpening block) between the punch and its spring guide stop to keep the punch in stop.

- Inconvénients de cette solution : longueur d'affûtage très limitée, cales d'affûtages nécessaires, clef pour vis de verrouillage du guide ressort et te te de frappe. Temps de montage et réglage de ltensemble. Fatigue du ressort suivant le réglage et l'épaisseur de la tete de frappe. - Disadvantages of this solution: very limited sharpening length, necessary sharpening shims, key for locking screw of the spring guide and impactor. Assembly time and adjustment of the assembly. Fatigue of the spring depending on the setting and thickness of the impact head.

I) et dégagé à sa partie inferieure au p sur une hauteur maxi suivant le.ss. - Figure I: - Mark 4 is a nut washer for adjusting and blocking the tube (rep. 3) and the washer (rep. 4) on the punch guide (rep. 5) - The punch guide (rep. 5) tapped at its upper part to receive the tube (ref. 3) - The punch (rep. 6) is threaded at its upper part to receive the striking head (rep. I) and released at its lower part at p over a height max according to the.ss.

- Le réglage de la mise en butée du poinçon (rep. 6) sur le tube (rep. 3) se fait en vissant ou dévissant la rondelle (rep. 4) et le tube (rep. 3).- The setting of the punch stop (rep. 6) on the tube (rep. 3) is done by screwing or unscrewing the washer (rep. 4) and the tube (rep. 3).

- Le réglage de l'ensemble se fait avec l'aide de la tette de frappe (rep. I) - Figure I - Avantages :
- L'invention figure I permet de multiplier la durée de vie du poinçon de 3 à 7 selon et de réduire d'autant son prix.- The adjustment of the assembly is done with the help of the hitting plate (rep. I) - Figure I - Advantages:
- The invention in FIG. 1 makes it possible to multiply the life of the punch from 3 to 7 depending on and to reduce its price accordingly.

- Autres avantages du dispositif, il supprime les cales d'affûtages, la clef de serrage et permet un réglage rapide et précis. - Other advantages of the device, it removes sharpening shims, the tightening key and allows quick and precise adjustment.
