Definitions
- the present invention relates to an indirect fire sealing apparatus, comprising a piston mounted in a barrel for, under the action of the combustion gases of a propellant charge, driving a pad for fixing a part on a support, means piston damping being provided between the barrel and a buffer guide disposed in front of the barrel, to absorb the excess propulsion energy of the piston and limit its stroke.
- Sealing devices of this type are often used for cladding buildings, such as hangars. It is, for example, and using short buffers, to fix cladding sheets on beams with a cross section, for example in I.
- the thicknesses of the support materials for receiving the fixing buffers are variable from one material to another, and it is necessary to ensure the regularity of the insertion of the pads in these materials.
- I-beams to be covered with thin sheets, it often happens that operators work blindly, without knowing if they are pulling in the soul of the beams, in their thin side wings, or even next to it.
- the buffers could be too deep, which would be detrimental to the quality of the fixing, but if it is side by side, they could cross the thin sheets like a a real projectile animated at a still high speed, if the sealing device was not precisely provided with the damping means of the piston which limit its stroke, not to mention the devices which are based on the absorption of the excess of power by the depression of the buffer itself, and in which the piston can protrude out of the buffer guide.
- the damper of the piston is therefore intended to limit, or control, the stroke. Indeed, it is sufficient to ensure the position of the piston at the moment when, so to speak, it releases the buffer, because at this moment, the kinetic energy of the buffer only represents a very small portion of the propulsion energy, insufficient for it to continue its sinking stroke. In other words, as soon as the tampon is released by the piston, it stops.
- shock absorber Several types are already known, non-elastic steel rings, on the one hand, and rings made of elastic material, for example polyurethane, on the other hand.
- Steel rings offer the advantage of good driving precision, but they have the disadvantage of increasing the risk of the piston breaking by sudden stop.
- the elastic rings do not have this drawback. But due to the fact that they are stressed in a large and frequent manner, they deform and even fall apart to the detriment of the precision of positioning of the piston and of the functioning of the tool.
- the present invention therefore aims to provide an indirect fire sealing apparatus, in which the axial position of the piston after the shots is always the same and determined with very good precision.
- the present invention relates to a device for indirect fire sealing of the type mentioned above, characterized in that the damping means comprise, in combination, at least one ring of rigid material, shaped to cooperate with the head of the piston, and at least one intermediate ring of elastic material, disposed between the rigid ring and the buffer guide.
- the rigid ring can begin to absorb a large part of the excess propulsion energy before moving forward and compressing the elastic intermediate ring between it and the tip guide, without risk of causing the piston to rupture.
- the piston head is hollowed out to receive the load carrier, whereby the robustness of the piston remains preserved despite the reduction in its weight which, for its part, is conducive to its good damping.
- the sum of the axial lengths of the rigid ring, of the elastic ring, in its compressed state, and of the buffer guide, on the one hand, as well as the length of the front part of the piston intended to protrude out of the elastic ring, on the other hand, are such that the front end of the pistion, after firing, does not protrude out of the buffer guide.
- a second intermediate ring of rigid but slightly deformable material movable axially between the rigid ring and the buffer guide shaped for this purpose.
- the second intermediate ring is used to limit the forward movement of the rigid ring before a power residue is transmitted to the buffer guide through it.
- the piston head of the device of the invention is frustoconical, therefore of large area, and the rigid ring has a bore of corresponding shape, which offers the best solution to the problem of damping posed.
- the sealing device which will be described is used above all to fix parts 1, such as cladding sheets, on supports 2, such as hangar beams, using buffers which are advantageously in the form of nails with short rods. 3 and big-headed 4.
- the apparatus of the invention therefore comprises a barrel block 5, in fact a barrel 51 proper and a load carrier 52 integral with the barrel, in which is mounted, for sliding axially, a piston, or counterweight, 6, and a buffer guide 7.
- a shoulder spacer 8, integral with the buffer guide 7, comprises, at the rear, an internal annular rim 9 intended to cooperate with an external annular rim 10 which is provided, at the front, with the barrel 51 , so that, when the device opens after a shot and before the loading of a new propellant charge, the drive of the buffer guide 7 forwards drives the barrel block 5 with it, while allowing , at the time of the firing and under the action of the exhaust gases, the retreat of the barrel 51 until its front edge 10 comes into abutment against the rear edge 9 of the spacer 8.
- the piston 6 comprises a head 11 and a rod 12.
- the head 11 comprises an annular rear part 13, hollowed out to receive, in the closed position of the apparatus and therefore ready for firing, the load carrier 52, and a front part 14 frustoconical, flared towards the rear, having a relatively large surface 15.
- the rear of the head 11 of the piston has an external flange 16, by which the piston 6 slides in the barrel 5, and which is intended to cooperate with a retaining pawl 17 secured to the barrel holder, not shown, in which the barrel is mounted sliding, the pawl 17 being able to slide in a slot 53 mengaée in the barrel.
- a retaining pawl 17 secured to the barrel holder, not shown, in which the barrel is mounted sliding, the pawl 17 being able to slide in a slot 53 mengaée in the barrel.
- the load carrier 52 the front part of which is therefore intended to engage in the rear recess of the piston and in which a nozzle 19 for the propellant gases is formed, comprises a rear part intended to receive, in a chamber combustion, a propellant charge 20 intended to be struck by a striker carried by the cylinder head of the device.
- An internal frustoconical bore 23 is formed in the ring 22, of shape complementary to that of the front part 14 of the piston head.
- a second intermediate ring 27 also in the form of a sleeve and of rigid but slightly deformable material, of external diameter equal to the internal diameter of the uncompressed ring 24, of internal diameter slightly greater than the diameter of the rod 12 of the piston, and of axial length equal to that of the uncompressed ring 24.
- a central bore 28 for receiving the buffer is formed in the buffer guide 7, from its front end face 29, of diameter greater than that of the central bore 26 for passage of the piston rod and into which the central bore opens. rear 26.
- the sum of the axial lengths of the rigid ring 22, of the compressed elastic intermediate ring 24, and of the buffer guide 7, is slightly greater than the sum of the axial lengths of the frustoconical part 14 of the head and of the piston rod 12 6. Or, the lengths of all these parts are such that the piston 6 cannot protrude from the buffer guide 7.
- the arming of the device and the firing are carried out in one case as in the other quite normally.
- the piston 6 is propelled forward by driving the buffer 4 in the part 1; the frustoconical part 14 of the head abuts against the corresponding bore 23 of the rigid ring 22 ( Figure 2).
- the rigid ring 22 moves forward, compressing the elastic ring 24 between the front face 30 of the rigid ring 22 and the rear face 31 of the buffer guide 7, the space annular 32 allowing the elastic ring 24 to swell, and by moving the second deformable intermediate ring 27 in the recess 25 in the rear part of the buffer guide 7 (FIG. 3).
- the energy residue is transmitted by the ring 27 to the buffer guide 7 bearing on the part 1.
- the second rigid intermediate ring 27 under the action of the energy transmitted by the piston, gradually deforms by compression between the front face 30 of the rigid ring 22 and the bottom of the recess 25 of the buffer guide, so that when the device is no longer new, the energy residue is transmitted to the buffer guide only after an axial displacement of the rigid ring 22 slightly greater than the depth of the recess 25.
- the ring 27 no longer deforms.
- the axial dimension of the rigid intermediate ring 27 could, in the new state, be smaller than that of the elastic intermediate ring 24, in its uncompressed state, which would avoid having to spare the recess 25 for receiving the ring 27 at the rear of the buffer guide 7.
- the buffer guide 7 is then either propelled forward if, at the location considered, the support is not under the part, that is to say if the latter can deform under the force, either the entire device, with the exception initially of the buffer guide and the spacer, moves back under the action of the exhaust gases, the rim 10 of the barrel 51 leaving the rear face of the rigid ring 22 to abut against the rim 9 of the spacer 8 ( Figure 3).
- the annular space 33 existing between the two flanges 9 and 10, just before firing, aims to allow relative movement of the barrel 51 and the piston 6 and thus avoid a brutal shock at the time of the damping of the piston which can cause inertia parts ruptures.
- the front end of the rod 12 of the piston 6 is set back relative to the front face 29 of the buffer guide 7. Even if the apparatus is used to draw, so to speak, into the void , that is to say on a piece to be fixed of small thickness in a place where it is not applied to its support, the piston remains inside the device. It is a guarantee of security and quality of the binding.
- a shock-absorbing device comprising a single rigid monobloc ring 22 and a single elastic monobloc ring 24. It would not be departing from the scope of the present invention to provide, instead of one, several rigid rings and, also instead of 'one, several elastic rings. Likewise, the elastic ring 24 could no longer be outside but inside the rigid deformable ring 27.
