Definitions

  • a rammer comprises at least one pestle which has a strong sole secured to the lower end of an I-beam.
  • the core of this I is equipped on its two faces with a lining with a high coefficient of friction and cooperates with two opposite eccentric wheels driven in rotation. At each turn, the eccentric wheels clamp the web of the profile together and propel it vertically upwards.
  • the pestle is released and falls freely on the layer of carbon which has just been deposited in the box.
  • each pestle When the box is full, each pestle is raised and is immobilized in the upper part of the stroke to allow the box to be released. This stop is obtained by clamping jaws of the profile to prevent the pestle from falling.
  • the pestle is subjected to unilateral heating and cooling which generate deformations which harm to the quality of the adhesion obtained and even to the correct subsequent operation of the pestle. It is therefore necessary, in each position, to subject the profile to a prestress opposing these deformations.
  • the present invention intends to propose means for simplifying the installation or replacement of these friction linings.
  • this machine comprises, on a frame, a support for the profile in a position where the core is vertical, this support being disposed between two horizontal jaws of lengths at least equal to that of the linings to be placed on the profiled, these jaws being coupled to motor members to bring them closer or separate them from one another in a movement perpendicular to the core of the profile and to keep them in a tight position on the core with a determined force, the jaws being provided with means for heating and cooling their surface facing one another.
  • one of the jaws is fixed in sliding with respect to the frame, the support of the profile being mounted movable in sliding with respect to the frame so as to be able to be moved towards and away from the fixed jaw during movement of the other jaw.
  • the machine comprises a second support for the profile constituted by at least two arms retractable between a first position where they are under the first support and a second position where they are above this first support, each arm comprising means for clamping the profile rotatably mounted in this arm around an axis parallel to that of the profile.
  • the jaws are pivotally mounted relative to the frame between a first position where their active face is vertical opposite one of the other and a second position where their active face is horizontal facing upwards.
  • the movable jaw is mounted on a carriage sliding on the frame perpendicular to the first support, the drive members being constituted by jacks coupled between the frame and this sliding support, the means for tilting jaws being formed, for the movable jaw by a drive wheel rotatably mounted on the carriage cooperating with a fixed rack integral with the frame when the carriage is moved in this area of the frame, and for the fixed jaw by an elastically extendable lever coupled between the first and second jaws.
  • the second support integral with the first jaw, the simple control of the clamping or loosening of the jaws makes it possible to accomplish all the movements and this, in synchronized manner.
  • Figure 1 should be understood as a simplified diagram of the means used in the machine according to the invention.
  • the section 1 to be treated is here shown resting on a horizontal support 2 so as to have its core 1 has vertically.
  • the support 2 is arranged between two jaws 3 and 4 which extend parallel to each other and to the support 2.
  • the length of the jaws is at least equal to that of the lining to be placed on the profile (of the order of a few meters).
  • the support 2 comprises an armature 5 for supporting rollers or rollers 6 on which the profile 1 can be slid from a longitudinal end of the machine.
  • This support can be in several sections 2 a , 2 b independent of each other separated by spaces such as 7 for the vertical passage of a secondary support 8, normally retracted under the profile 1.
  • the support 2 and the jaws 3 and 4 are supported by a frame not shown in FIG. 1.
  • Means for driving the jaws are coupled between the latter and the frame to move them away or bring them closer to each other so to tighten between them the core 1 a of the support and to remove this tightening.
  • the support 2 is fixed relative to the frame and that the jaws are movable on either side of this fixed support.
  • the support 2 is also movable to be driven towards the jaw 3 by the jaw 4.
  • the means of connecting the support 2 by the jaw 4 are symbolized by the elastic connections 9 and 10 disposed between the support and each of the jaws which compress during approximation of the jaws by moving the support 2 in the direction of the jaw 3 by a value substantially equal to the half-stroke of the jaw 4, and which relax during the distance of the jaws to move, from this same value, the jaw support 2 3.
  • Each jaw 3, 4 has an active face 3 a , 4 a which forms a support sole for the lining to be applied to the profile, this sole being able to be heated and cooled by heat transfer means located in 3 b , 4 b in each jaw in line with the soles 3 a , 4 a (water or steam circulation circuit, resistance electric, air circulation circuit .).
  • each jaw 3 and 4 is in two parts articulated around an axis 11, 12 parallel to the direction of the profile 1 on its support.
  • the two parts comprise a portion of the fixed frame 13 a and the jaw proper 13 b .
  • the first part 14 a constitutes a carriage sliding on the frame on which the drive members act, the second part 14 b constituting the active part of the vice.
  • the secondary support 8 comprises at least two forks (only one is shown in the figure) which can be maneuvered vertically according to the arrows B to take over the profile 1 and lift it from the support 2.
  • These forks 15 each have a central portion 16 having the profile of the clamp means and rotatably mounted about the longitudinal axis of the profile in an outer support which allows, once the raised profile, placing its core 1 has horizontally in one and the other of two positions, in order to have easy access to each of the faces of this core in order, for example, to remove the used lining which would have previously undergone a thermal take-off treatment (by means of the jaws 3 and 4).
  • Figures 2 and 3 illustrate a preferred embodiment of the machine shown schematically in Figure 1.
  • Figure 2 is intended to illustrate the means for the synchronized operation of the jaws 3 and 4 both in their movement of movement / distance as in their movement around their articulation.
  • the reference 20 is attached to the frame of the machine part of which constitutes the fixed support 13 a of the jaw 3 on which it is articulated.
  • the base (or carriage) 14 a sliding of the jaw 4 is coupled to the rod of a cylinder 21 (in fact the machine comprises a plurality of jacks regularly distributed along the jaw 4).
  • the portion 14b of the jaw 4 is integral with a toothed wheel 22 which rotates with it around the axis 12. This toothed wheel 22 cooperates with a rack 23 carried by the frame during the final phase of retraction of the jack 21 or its first extension phase.
  • the part 14b of the jaw 4 is pivoted around the axis 12. The jaw 4 therefore passes from its position 4 is directed to the section 1 ( Figure 2) to its position 4 a horizontal ( Figure 3).
  • the synchronized pivoting drive of the jaw 3 is ensured by a connection of the jaws 3 and 4 by means of an elastically telescopic lever 24 (in reality two levers 24 connect the jaws 3 and 4 at each of their ends, beyond the support ends 2).
  • Each of the jaws 3 and 4 has an arm 25, 26.
  • the arm 25 is articulated to the lever 24 about an axis 27 carried by a slide 28 sliding along the lever 24 and subjected to the antagonistic effects of two springs 29 and 30.
  • the arm 26 is in turn articulated at the end of the lever 24 about an axis 31.
  • the axes 11, 12, 27 and 31 form the vertices of a deformable quadrilateral.
  • the opening of the jaws (by action of the jack 21) first comprises a phase of sliding of the lever 24 relative to the slide 28 kept fixed under the effect of the spring 30.
  • the spring 30 is balanced by the spring 29, c '' is to say substantially at the moment when the wheel 22 attacks the rack 23, the beginning of the rotation of the arm 26 (combined with its sliding to the right of the figure) causes the jaw 3 to rotate around the axis 11, to the position shown in FIG. 3.
  • the spring 29 makes it possible to make the drive of the arm 26 more flexible by the lever 24 and to absorb the end-of-travel forces. Reverse rotation is obtained by extending the jack 21.
  • This figure also shows in 9 and 10 the elastic connection device of the support 2 to the jaws 3 and 4 which makes it possible to drive the support 2 in the direction of the jaw 3 during the closing of the vice and the move away from this jaw 3 when opening.
  • FIG. 3 illustrates a preferred embodiment of the auxiliary support 8.
  • the support 8 is integral with the pivoting jaw 4 so that the pivoting of the latter causes the support 8 to rise, which, in its movement, takes charge profile 1 to place it in the position shown in Figure 3.
  • the machine will include a support 8 in at least two parts distant from each other along the longitudinal axis of the profile.
  • the profile 1 to be relined is placed on the support 2, with on each face of the core 1 has its used lining. Removing it requires prior heating at a temperature of the order of 120 to 150 ° C. This heating is obtained by tightening the jaws 3 and 4 on the profile and by heating their sole 3 a , 4 a .
  • the machine according to the invention makes it possible to considerably simplify the maintenance operations of the rammers and to improve the quality of the lining.
