Definitions

  • the invention relates to a clamping tool and more particularly to a crimping.
  • the tool is thus provided with a clamp which is generally mounted so removable in order to adapt the suitable clamp according to the diameter of the fitting to crimp.
  • the jaws are actuated towards each other by the action of the piston of a jack fitted with two rollers which are moved in translation on inclined ramps arranged on the jaws so as to separate said ramps and bring together the jaws which pivot towards each other.
  • the piston first performs an idle stroke until the rollers reach the inclined ramps.
  • the tool Before therefore starting a crimp, the tool must operate for a some time without movement of the jaws.
  • the invention provides a tool which is in particular remarkable in that one of the jaws is pivotally movable relative to the other jaw which is connected to a fixed part of the actuation system, said movable jaw being connected by means of translational actuation by a link articulation partly secured to a lever forming a handle which is arranged so as to allow the movable jaw to be pivoted in one direction or in the other in two extreme positions, respectively opening and closing partial, by modifying the relative geometry of the articulation rods, while that the translational drive means can act on said rods to rotate the movable jaw, either in the direction of clamping the jaws after actuation from the handle to its extreme partially closed position, either in reverse loosening before actuating said handle to its open position.
  • the articulation connecting the movable jaw to the translative actuating means comprises at least two pivoting links between them by one of their ends whose other ends are pivotally mounted respectively on the movable jaw and on said translational drive means, while the handle is integral with the link (s) pivotally mounted on the translative drive means and at least one stop and at least one means conjugate are provided on the rods to cooperate in order to limit deformation geometric of said links by the handle in the extreme closed position partial jaws, so that the rods are locked and rigidly linked to each other during the pushing actuation of the translational drive means to ensure the clamping of the jaws.
  • the stop for limiting the geometric deformation rods is arranged so as to retain at least one of the rods when the latter, actuated by the handle, have taken a position such that the axis of common pivoting of the two rods is passed from one side to the other of the line geometric formed by the pivot axes of the other two ends of the rods.
  • the limiting stop is arranged so that in the position locking rods, after actuation of the handle, but before actuation the translational drive means, the common pivot axis of the rods and the pivot axis of the link with the drive means determine a line substantially parallel to the direction of the translational movement of said drive means.
  • the articulation connecting the movable jaw to the translative actuation means comprises an individual link articulated on said translational actuating means and a pair of links articulated on said jaw mobile and on the individual link which they enclose by their corresponding ends, the stop for limiting the movement of the rods being formed by a spindle, while the combined means intended to cooperate with said stop is a shoulder, or a notch fitted on the individual link.
  • the jaw connected to the fixed part of the actuation system comprises the pivot axis of the movable jaw, said axis being arranged in the contact plane of said jaws.
  • the jaw connected to the fixed part of the actuation system is rotatably mounted on said fixed part and preferably, said jaw is positioned so as to present its clamping plane substantially perpendicular to the direction of movement of the translational drive means .
  • the actuation system comprises for example a cylinder, the drive means translative being produced by the end of the cylinder rod and / or a part attached to it.
  • each jaw has a housing intended to receive a crimping die.
  • the invention relates to any type of clamping tool also including in general, the tools for cutting in shear.
  • a tool according to the invention here in the form of a tool crimping tool intended to crimp for example a fitting 1 on a pipe 2 ( Figures 1 and 3 to 5).
  • the invention can of course relate, as already said, to other types clamping tools.
  • the tool according to the invention comprises a jaw 3 provided with a part of clamping 3a and a fixing part 3b on which is mounted a movable jaw 4 formed by a clamping part 4a and a shank 4b, which can pivot around a pivot axis 5 integral with the fixing part 3b of the jaw 3, said axis 5 being arranged here substantially in the contact plane of the clamping parts of the two jaws.
  • the fixing part 3b of the jaw 3 is fixed on a drive system, here in the form of a hydraulic cylinder 6 partially shown in the drawings, and which comprises a cylinder 6a, a sliding piston 6b provided with an extension or rod 6c, itself provided at its end with a head 7 (FIGS. 2 to 5), the assembly formed of the piston 6b, the rod 6c, the head 7 or to simplify, the latter alone, forming a translational drive means.
  • a drive system here in the form of a hydraulic cylinder 6 partially shown in the drawings, and which comprises a cylinder 6a, a sliding piston 6b provided with an extension or rod 6c, itself provided at its end with a head 7 (FIGS. 2 to 5), the assembly formed of the piston 6b, the rod 6c, the head 7 or to simplify, the latter alone, forming a translational drive means.
  • the actuation of the jack is ensured by any means such as an electric pump, for example.
  • the fixed part 3b of the jaw 3 is fixed on the cylinder 6a, advantageously in a rotating manner to allow adjustment in position.
  • the clamping part 3a of the jaw 3 has a clamping plane so arranged substantially perpendicular to the direction of movement of the head 7, that is to say of the translational drive means.
  • the head 7 of the actuation system is connected to the tail 4b of the jaw 4 by an articulation 8 with links.
  • the articulation 8 here presents an individual link 8a and a pair of links 8b, 8'b of which only one link for the pair 8b, 8'b is visible in Figures 1 and 3 to 5 (only Figure 2 shows the three links).
  • the links 8a; 8b, 8'b can move at least partly in the part 3b of jaw 3 which has a U-shape at this point, as shown well figure 2.
  • One end of the individual link 8a is articulated at the ends corresponding to the pair of links 8b, 8'b around a common axis 9.
  • the other ends of the links 8a and 8b, 8'b are pivotally mounted respectively on the head 7 of the actuation system around an axis 10 and on the tail 4b of the movable jaw 4 around an axis 11.
  • the link 8a is also secured to a lever forming a handle 12.
  • the links 8a and 8b, 8'b form a joint of the type knee brace whose geometry is modifiable by the action of the handle 12, so that an action of the latter in one direction or the other makes it possible to rotate the jaw movable 4, either towards the jaw 3 by bringing it closer, or on the contrary in direction reverse by removing it.
  • the rod 8a is provided with a shoulder or notch 13 while the pair of links 8b, 8'b is provided with a pin forming a stop 14 intended to cooperate with said notch 13, as will be explained below.
  • clamping parts 3a, 4a of the jaws 3 and 4 respectively are provided with housings, here semi-circular, intended to receive matrices of crimping 15, 16 removable to adapt to various diameters of fittings 1 to crimp on various pipes 2.
  • the tool looks as shown in Figures 1 to 3, that is to say that jaws 3 and 4 are open so that you can pass them around fitting 1 to be crimped.
  • the jaws 3 and 4 being positioned, as has just been said, we operate the handle 12 (in relation to the drawings, it is raised) so as to modify the geometry links 8a; 8b, 8'b, the common axis 9 of said links describing a circle around the axis 10 until the notch 13 of the link 8a comes into contact with the stop 14 as shown in FIG. 4. During this action, the movable jaw 4 pivots towards the jaw 3 which is fixed relative to said jaw 4.
  • the line connecting the pivot axes 9 and 10 is substantially coaxial with the axis of the cylinder 6, or more generally, parallel to the direction of the translational movement of the head 7.
  • the clamping pressure is such that the handle 12 cannot be actuated and the pressure of cylinder 6 must first be released to return to the position of figure 4.
  • the handle 12 makes it possible to constitute not only a means of operation and closure but also an ergonomic means of support and guidance particularly even more practical by the rotary mounting of the jaw 3 on the system actuation, as specified above.
