Abstract

Portable manual bending press. The bending press comprises two main steel parts joined together to form an assembly which can move by means of two screws. The female part consists of a frame 1 comprising a single 90 DEG V-shaped groove. The male part is formed by a single plate 5 terminated by a 90 DEG V-shaped tip 6. The vertical slots 3 and 7 machined into the plate and the frame at regular intervals permit the passage of the bent edges of the metal sheet 12 in the case of perpendicular bending. The screws 10 which pass through the holes 8 and are screwed into the tapped holes 4 vertically guide and clamp the plate to the frame, and by means of the male and female 90 DEG Vs, permit the bending of the metal sheet. The springs 9 automatically raise the plate. The removable support 11 serves to fix the bending press.

Description

Presse plieuse manuelle portative. Portable manual press brake.

l'invention concerne une petite presse plieuse portative, se fixant généralement dans un étau et fonctionnant manuellement. the invention relates to a small portable press brake, generally fixing in a vice and operating manually.

Il existe de nombreuses presses pileuses électriques ou hydrauliques de moyenne ou grande capacité. Mais, ces machines, essentiellement destinées aux professionnels, sont encombrantes, non mobiles et d'une conception complexe. Elles sont conçues pour effectuer une très grande variété de pliages au moyen d'une multitude d'outils interchangeables. Ces machines se composent généralement d'un bâti formant la table ou viennent se poser les outils à gorges multiples (parties femelles) et d'une pièce mobile verticalement où sont fixées les différentes lames (parties mâles). On change les outils suivant les travaux.Exemple e lorsque l'on doit effectuer plusieurs pliages perpendiculaires les uns aux autres, il est indispensable de disposer ou de fabriquer à la dimension voulue, soit la lame dans le cas de plis intérieurs, soit l'outil à gorge dans le cas de plis extérieurs.Si cette conception permet à ces presses pileuses une très grande variété de travaux, elle présente l'inconvénient dt8tre couteuse et donc d'interdire leur mise à la disposition des bricoleurs contrairement à toutes sortes d'autres machines0
la presse pileuse, objet de l'invention, comporte deux pièces principales en acier réunies en un assemblage mobile par deux uns, la pièce femelle est constituée d'un bAti dont la partie supérieure comporte sur toute sa longueur une gorge unique en forme de V à 900. le b#ti comprend également à chacune de ses extr#mités un perçage vertical taraudée la pièce màle est constituée par une lame unique dont la partie inférieure se termine par une pointe en forme de V à 900. La lame comprend également à chacune de ses e trtmités un perçage vertical. les vis font office de guide à la lame qui peut ainsi coulisser verticalement par rapport au bâti, Ils servent également de points de force en assurant le serrage de la lame sur le bâti et par l'intermédiaire des
V mssle et femelle, au pliage de la talez lie pliage peut varier de O à 900 suivant le serrage, La partie inférieure (pointe en V) de la lame et la partie supérieure (gorge) du bti comportent sur toute leur longueur des fentes d'environ trois millimètres de large et vingt cinq millimètres de haut pratiquées verticalement à intervalles réguliers (trente à quarante millimètres).Ces fentes sont destinées à permettre le passage des bords pliés de la tôle lorsque l'on effectue des pliages perpendiculaires à ces bords. Elles suppriment dans une très large mesure l'inconvénient d'avoir à fabriquer l'outil à gorge ou la lame à la dimension voulue. Des ressorts enfilés dans les vis entre le Bâti et la lame assurent automatiquement le relevage de cette dernière lors du desserrage.Un support amovible formé par une cornière venant se fixer sous le baAti sert à maintenir la presse plieuse dans l'étau. les avantages de cette presse plieuse sont construction simple, légère et pas conteuse, fonctionnement sinople et pratique, mobilité et capacité de travail importante (environ 70 cm de longueur, et épaisseur 1s5 mm).
There are many medium or large capacity electric or hydraulic piling presses. However, these machines, mainly intended for professionals, are bulky, not mobile and of a complex design. They are designed to perform a very wide variety of bends using a multitude of interchangeable tools. These machines generally consist of a frame forming the table where the multi-grooved tools are placed (female parts) and a vertically movable part where the different blades are fixed (male parts). The tools are changed according to the work. Example e when it is necessary to make several folds perpendicular to each other, it is essential to have or manufacture to the desired dimension, either the blade in the case of interior folds, or the grooved tool in the case of exterior folds. If this design allows these piling presses a very wide variety of work, it has the drawback of being expensive and therefore of prohibiting their provision to DIY enthusiasts unlike all kinds of other machines0
the piling press, object of the invention, comprises two main steel parts joined together in a movable assembly by two ones, the female part consists of a frame whose upper part comprises over its entire length a single V-shaped groove at 900. the b # ti also includes a tapped vertical bore at each of its ends. the male part is constituted by a single blade, the lower part of which ends in a V-shaped point at 900. The blade also includes at each of its ends has a vertical hole. the screws act as a guide for the blade which can thus slide vertically relative to the frame, They also serve as points of force by ensuring the clamping of the blade on the frame and by means of
V mssle and female, when folding the heel, folding can vary from 0 to 900 depending on the tightening, The lower part (V-shaped point) of the blade and the upper part (groove) of the frame have slots throughout their length. '' about three millimeters wide and twenty five millimeters high made vertically at regular intervals (thirty to forty millimeters). These slots are intended to allow the passage of the folded edges of the sheet when performing folds perpendicular to these edges. They largely eliminate the disadvantage of having to manufacture the grooved tool or the blade to the desired size. Springs inserted in the screws between the frame and the blade automatically lift the latter during loosening. A removable support formed by an angle iron fixed under the baAti is used to hold the press brake in the vice. the advantages of this press brake are simple construction, light and not conteuse, sinople and practical operation, mobility and important working capacity (about 70 cm in length, and thickness 1s5 mm).
