Definitions
- the invention relates to a blade holding plate for bolt cutter.
- each axis 4a, 4b is constituted by a stepped axis the rod of which passes through cylindrical punches formed in the blades and in each of the maintenance plates 3a, 3b.
- the free end of each axis is riveted on one of the plates by deformation, hot or cold, of its free end.
- the movements of the blades causes, by friction, the rotation of the axes 4a, 4b, which leads to wear of these pins and the punches receiving them, and, consequently, to the formation of radial clearances.
- the blades are less and less held by their plates 3a, 3b and can therefore shift one with respect to the other, thus shifting their cutting edges on both sides of the sectioning plane, which favors the tilting of the bolt cutter providing poor sectioning by shearing of the part.
- the object of the present invention is to remedy these disadvantages.
- each of the two punchings of the blade holding plate against which the ends of axes are riveted has at least one groove longitudinal circumscribed to the cylindrical envelope necessary for the passage of the axis and able, when riveting the axis, to receive part of the material this axis to form a means of setting in rotation thereof.
- the groove is made on the side of the punching which adjoins the other punching made in the same plate.
- the means of setting in rotation of each axis are diametrically opposite to the part of the axis receiving the reaction force during the sectioning of a part, and, consequently, are subjected to an effort of much more limited matting.
- the head A of the bolt cutter is equipped with two identical holding plates.
- each of the punches 6, for the passage of the axis 4b or 4a corresponding present, as shown in more detail in Figure 3, at least a groove 5 and in this case three grooves extending over all the thickness of each plate.
- Figure 3 clearly shows that the grooves 5 are circumscribed to the cylindrical envelope necessary for the passage of the axis 4a or corresponding 4b, i.e. are outside of this envelope for allow free passage of the axis.
- Figure 2 shows that, preferably, the grooves 5 are made on the edge of each punching facing inward, i.e. on the edge which adjoins the edge of the other punching, so that these grooves are diametrically opposite to the punching area receiving the force of reaction to the cut.
- each end of each axis 4a, 4b is riveted and therefore comprises, locally, lugs 8 cooperating with grooves 5 arranged in each of the plates 3a, 3b, but it is obvious that the timing of each axis can be ensured by a arrangement of the punches 6 of only one of the plates 3a, 3b.
- the splines can have any cross section, be single or multiple, provided they are circumscribed to the cylinder necessary for the passage of the axis and that they allow the formation of a lug radial 8 having a cross section sufficient to ensure the setting in rotation of the axis relative to the plate it crosses.

Abstract
Description
Claims (2)
- Plaque de maintien des lames d'un coupe boulon dans lequel les lames de coupe (2a, 2b) sont disposées entre deux plaques (3a, 3b) sur lesquelles elles sont articulées par des axes (4a, 4b) traversant des poinçonnages (6) de ces plaques, chaque axe d'articulation (4a, 4b) étant calé en translation axiale, au moins d'un côté, par un rivetage, caractérisée en ce que chacun des deux poinçonnages (6) de la plaque de maintien (3a) contre laquelle les extrémités des axes (4a, 4b) sont rivées, comporte au moins une cannelure longitudinale (5) circonscrite à l'enveloppe cylindrique nécessaire au passage de l'axe (4a ou 4b) et apte, lors du rivetage, à accueillir une partie de la matière de cet axe pour former un moyen (8) de calage en rotation de celui-ci.
- Plaque selon la revendication 1, caractérisée en ce que la cannelure (5) est réalisée sur le côté du poinçonnage (6) qui jouxte l'autre poinçonnage réalisé dans la même plaque (3a, 3b).
