Abstract

The invention relates to rotary shears making it possible to cut metal in sheet form, its use being for any substance or object forming an angle. It consists of a supporting structure 4; two manipulating hand grips 7 and 8, two cutting wheels; a raceway 1-2-3; a slightly upwardly inclined flat part allowing the metal once cut to be ejected in the same alignment. The application is intended for cutting metals in sheet form used for covering.

Description

L'invention concerne une cisaille rotative légère et transportable destinte à couper les matières ou métaux en feuille et employas en couverture tel que Zinc - cuivre - inox - aluminium - etc
Il existe des cisailles rotatives mais qui, de par leur conception et leur fonctionnement sont équipées d'un systame de guidage déporté extérieur au bati et munies de galets avec une rainure.Ces galets sont places de telle fa- çon que leur fonction est de rouler sur un rail de guidage indépendant et ser- vant de support b la cisaille rotative, ce système de rail est indispensable dans ce principe
D'autre part on connaît des cisailles rotatives dont la conception du bâti est prévue pour que le métal en feuille, une fois coupé, soit éjecté vers le bas ce qui entraîne de par la forme du bati uné- déformation du métal coupe
Ces cisailles rotatives ainsi conques ont pour inconvénient de ne pouvoir fonctionner qu'avec ce rail de guidage supplémentaire qui îui-mê doit être fixé sur une table de serrage prévue a cet effet ou sur une plieuse afin de maintenir la feuille de mataf serrés, ce qui necessite tout un appareillage et des montages volumineux et onersux.
The invention relates to a light and transportable rotary shear intended to cut materials or metals into sheets and used in covering such as zinc - copper - stainless steel - aluminum - etc
There are rotary shears but which, by their design and their functioning are equipped with a remote guiding system outside the frame and provided with rollers with a groove. These rollers are placed in such a way that their function is to roll on an independent guide rail and serving as a support for the rotary shears, this rail system is essential in principle
On the other hand, rotary shears are known, the design of the frame of which is provided so that the sheet metal, once cut, is ejected downward, which causes the deformation of the cut metal by the shape of the frame.
These rotary shears thus designed have the drawback of being able to operate only with this additional guide rail which itself has to be fixed on a clamping table provided for this purpose or on a folder in order to keep the sheet of mataf tight, this which requires a whole apparatus and bulky and onersux assemblies.

L'invention a pour objet une cisaille rotative légère ne déformant pas le métal coupe et dont la conception ne nécessite pas l'apport d'un rail de qui- dege supplémentaire ou de support pour fonetionner. The subject of the invention is a light rotary shear which does not deform the metal being cut and whose design does not require the addition of an additional quarry rail or support to operate.

La solution apportée par la présente invetion est l'apport d'un système de guidage intégré servant de support au bsti de la cisaille rotative. The solution provided by the present invetion is the provision of an integrated guidance system serving as support for the bsti of the rotary shears.

Ce système est constitué d'un chemin de roulements (1-2-3) place sur la partie du bâti permettant un contact direct de ces roulements avec le@métal a couper (12), de ce fait c'est le métal b couper (12) qui devient le support de la cisaille rotative
L invention est caractérises par le fait que la conception du bâti est aons- titube, après la coupe des molettes (Il) d'une partie plate et tPhs légèrement inclinée vers le haut (10) qui permet de soutenir le métal en feuille sur unmême plan at alignement qu'avant la coupe lui évitant ainsi toute déformation.
This system consists of a raceway (1-2-3) placed on the part of the frame allowing direct contact of these bearings with the metal to be cut (12), therefore it is the metal to be cut. (12) which becomes the support for the rotary shears
The invention is characterized by the fact that the design of the frame is aons-titube, after cutting the knobs (II) from a flat part and tPhs slightly inclined upwards (10) which allows the sheet metal to be supported on one plan at alignment than before cutting thus avoiding any deformation.

Les dessins annexes illustrent l'invention :
- La figure 1 représente une vue latérale montrant le chemin de roulements verticaux.
The accompanying drawings illustrate the invention:
- Figure 1 shows a side view showing the path of vertical bearings.

- La figure 2 représente une vus latérale montrant la partie plate légè- rament inclinée- vers le haut,
- La figure 3 représents une coupe verticale.
FIG. 2 represents a side view showing the flat part slightly inclined upwards,
- Figure 3 shows a vertical section.

La structure de la cissille rotative est constituée d'un bâti (4) en acisr, aluminium ou plastique, punie de 2 poiquées (7 et 8) qui sous le fait de la poussée antrainent 2 mpletten coupantes (5 et 6) en scier qui assurent la coupe du métal en feuille : à cet effat, ll existe une protsction des doiets (13). The structure of the rotary scissor consists of a frame (4) made of steel, aluminum or plastic, punished by 2 punches (7 and 8) which under the fact of the push cause 2 cutting mpletten (5 and 6) in sawing which ensure the cutting of sheet metal: for this purpose, there is a protection of the doiets (13).

La présente invantion aure des aoplications dans la bâtiment pour la coupe des métaux emplovés en couverture. The present invantion has aplications in the building for cutting the metals used on the cover.
