Definitions

  • the invention relates to a variable-controlled compressed air puncture device according to the preamble of the first claim.
  • variable control piercing device whose distribution element, adjacent and coaxial with the cylinder, comprises an upper body and a lower ring housing a movable fluid distribution spool, the body being provided with multiple coaxial channels for conveying the fluid. fluid formed in the thickness of its wall. Nevertheless, this arrangement of channels formed in the body, coaxially with it, requires that the channels are of a reduced diameter to preserve the integrity of the body and that they are numerous to convey the desired fluid flow. This therefore requires complex and expensive machining of the distribution element of the piercing device.
  • This document describes a pneumatic and variable-controlled puncture device comprising a cylinder assembly (B) and piston (K) for actuating a piercing element (implicit), and a variable-control (S) distribution part (implicitly).
  • the dispensing portion (S) having a movable sliding spool (S) and fluid dispensing slider, the dispensing portion (S) is housed in the cylinder (B) of the cylinder assembly (B) and piston (K), at its upper part (B) and coaxially with said cylinder, and said upper part of the cylinder (B) comprises two channels (n, F) of conveying the compressed air in sealed communication with the dispensing part (S) via radial channels (a, i, h), one of the conveying channels (F) being more particularly intended for the feeding of the cylinder assembly (B) and piston (K) in connection with the fluid supply section ( figures 1 and 2 ), and the control (f1, f2, f3) of movement of the spool (S) of the dispensing part (S) and the other conveying channel (n) is intended to allow alternatively relief of the piston (K; Figure 1 ) and the escape of the fluid (see Figure 2 )
  • the invention aims to overcome this drawback and proposes a piercing device according to the first compressed air and variable control claim comprising a cylinder and actuator piston assembly of a piercing element, and a variable control distribution portion of the compressed air to said cylinder and piston assembly, the dispensing part comprising an upper body, a lower ring and a movable fluid distribution slide slidably mounted between the body and the ring, characterized in that the dispensing part is housed in the cylinder of the cylinder and piston assembly, at its upper part and coaxially with it, the variable fluid control is housed in the head of the cylinder closing the upper part of the cylinder, being connected to a fluid supply section, and said upper portion of the cylinder has two channels for conveying compressed air in sealed communication with the dispensing portion.
  • radial channels of the outer distribution part and adjacent to the dispensing part one of the delivery channels being more particularly intended to supply the cylinder and piston assembly in connection with the feed section.
  • the variable control part of the fluid, and at the movement control of the spool of the dispensing part and the other conveying channel is intended to alternatively allow the piston to be raised and the fluid to escape at the lower level of the cylinder and piston assembly, said channels having a section with groove shape open to said radial channels of the dispensing portion.
  • Said routing channel is naturally formed outside the dispensing part and advantageously communicates with low play and in a sealed manner with radial channels formed in the body and the ring of the dispensing part.
  • Said routing channel may extend coaxially and adjacent to the dispensing portion, along the length thereof, and be groove-shaped rotated with its opening to said radial channels of the dispensing portion.
  • the section of this groove advantageously half-cylindrical, may be relatively large, thus being able to pass a relatively large fluid flow.
  • this arrangement avoids forming in the body of the distribution portion coaxial channels, difficult to machine and multiple to increase the flow rate of the fluid, requiring only the machining of an internal groove on the wall of the cylinder, in its upper part adjacent to the dispensing part, and the machining of the radial channels in the dispensing part without limiting their section to the thickness of the body, this machining being significantly simplified relative to that of the aforementioned comparable device of the prior art and further not limiting the section of the radial channels of the distribution part.
  • variable fluid control is housed in the head of the cylinder closing the upper part of the cylinder, being connected to the fluid supply section by at least one flexible supply pipe, just below the operating handle of the piercing device, which is attached to said cylinder head.
  • Said upper part of the cylinder advantageously comprises two channels for conveying the compressed air in communication with the dispensing part, coaxial thereto and preferably diametrically opposed relative to the axis of the cylinder and piston assembly, one of the routing channels being more particularly intended for supplying the cylinder and piston assembly, in connection with the supply section and the variable fluid control part, and with the movement control of the part of the drawer and the other channel is intended to allow alternately the relief of the piston -and the escape of the fluid at the lower level of the cylinder and piston assembly.
  • the ring of the distribution part advantageously comprises at least one radial exhaust channel connected to a radial channel opening out from the upper part of the cylinder, able to be opened or closed by the movable spool and allowing the opening of the escapement of the fluid at the raising of the piston. It further comprises at least one open drawer lift control channel in the lower position of the piston connected to a control channel of the cylinder opening therein above the piston in the down position.
  • the body of the distribution part advantageously comprises at least one radial exhaust channel, in a suitable position thereon to be opened or closed by the movable spool and to allow the opening communication towards said relief channel of the piston to the downward movement of the latter without compressing the fluid at the bottom of the cylinder.
  • the piercing device may comprise a small radial channel formed at the upper part of the body, said boot of the drawer control, allowing since stopping the piercing device directed upwards to push the movable drawer to the piercing element, and to establish the pressure in the cylinder, at the command, to start the movement of the piston.
  • the piercing device according to the invention can operate at high pressure of compressed air (7 bars for example) or at low pressure (less than 2 bars) by increasing the sections of the channels to obtain a similar service effect, or between both.
  • the piercing device 1 essentially comprises a cylinder-piston assembly 5 for actuating a lower piercing element 7, a distribution part 9 for the compressed air (at 7 bar) and an upper head 11 for closing the cylinder. 13 of the cylinder-piston assembly 5.
  • the dispensing part 9 has a cylindrical shape that is coaxial with the cylinder 13, comprising a cylindrical upper body 15 and a lower ring 17 that is sealed (by interlocking) to the body 15, and a movable cylindrical spool 19 mounted sliding with low play and in a leaktight manner. , on a short stroke (about 1 cm), between the body 15 and the ring 17.
  • the upper head 11 is provided with an upper D-shaped operating handle 21 of the piercing device.
  • the handle 21 comprises a trigger 23 for controlling the piercing device 1, able to be pressed in a variable manner by the operator to allow variable control of the piercing device 1.
  • This trigger 23 in operating position opens more or less a valve 25 for supplying compressed air to the device, which is movably mounted in the head 11 relative to a valve seat 27 of a fluid supply section 29 connected by a flexible hose 31 laterally to the head 11.
  • the dispensing part 9 is housed in the upper part 33 of the cylinder 13 close to the upper head 11 carrying the operating handle.
  • the ring 17 and the body 15 being substantially of the same external diameter as the cylinder 13, the upper part 33 of the latter is slightly enlarged with a recess 35 relative to the body of the cylinder 13, a diameter greater than that of the body of cylinder 13 to contain the dispensing portion 9.
  • This upper portion 33 is provided with two longitudinal channels coaxial with the cylinder 13, 37, 39, diametrically opposed and extending along the length thereof.
  • These channels 37, 39 ( Fig. 7 ) have a half-cylindrical section (groove-shaped) open on the body 15 and the ring 17 of the dispensing part.
  • the upper channel 37 (above the axis of the cylinder in the drawing) is connected to an upper longitudinal channel 41 extending in the thickness of the cylinder body 13 and along its length to the bottom of the latter.
  • This channel 41 is said relief channel of the piston 3 allowing it to return to the upper portion 33 of the cylinder when it reached the bottom 43 of the cylinder. It also allows, as previously mentioned, the escape of the air under the piston 3 in the stroke of the piston towards the bottom 43 of the cylinder, via two radial outlets or radial channels 45 provided in the body 15 and suitably opened by the movable drawer 19.
  • the other longitudinal channel 39 of the upper part 33 of the cylinder or lower longitudinal channel 39 is connected mainly to a radial channel 47 of the body for supplying compressed air to the cylinder, to a small radial channel 49 of the body for the control of the movement of the slide 19 and other radial auxiliary channels of the body 15 specified thereafter.
  • the ring 17 and the body 15 each comprise two radial exhaust holes or channels 51, 45 and in communication with corresponding radial through-holes of the cylinder 13.
  • the exhaust holes 51 of the ring are open at the raising of the piston 3 and simultaneously that of the drawer 19 to decompress the upper chamber 53 of the cylinder (above the piston).
  • the exhaust holes 45 of the body 15 allow the descent of the piston 3, conversely, the decompression of the lower chamber 55 of the cylinder (below the piston) via said relief channel 41 in communication therewith , while the drawer 19 is lowered and closes the exhaust holes 51 of the ring 17.
  • the operation of the piercing device 1 according to the invention is now described. It depends on the movement of the movable slide 19 which controls the circulation of the fluid. This displacement is related to certain surfaces of the slide in contact with the fluid, which will participate in combination with the displacement of the slide. These surfaces correspond respectively to the lower edge surface S1 of the slide, to an upper shoulder surface S2 of a drawer control chamber 57, delimited between the body 15 and the slide 19 and in communication with a control channel 59 longitudinal of the ring (itself in communication with a longitudinal channel 60 of the cylinder) and said radial control channel 49 of the body, and an upper edge surface S3 of the slide 19.
  • the fluid arrives from this channel in the cylinder chamber through an annular groove 61 formed in the body 15, which facilitates its routing.
  • the fluid pressure is applied to said surfaces S1, S2 and S3 and as S1 + S2> S3, the slide 19 initiates an upward movement.
  • the drawer 19 goes back ( Fig. 2 ) and disengages the escape holes 51 from the ring 17, thus losing the control pressure on S1 and S3 on the slide, but the pressure on the surface S2 is kept by the control channel 49 of the ring 17 and thus the drawer 19 continues to go up to the upper stop.
  • the feed groove 61 is then closed ( Fig. 3 ) by the slide 19, which opens a channel 62, 63 of the body by a substantially central peripheral groove 65 and communicates the fluid to the relief channel 41.
  • the piston of the cylinder 3 rises and the air of the upper chamber 53 s evacuated through the open holes 51 of the ring 17.
  • the drawer 19 having come down again ( Fig. 6 ) the upper chamber 53 is supplied with compressed air by the feed channel 47 and the piston 3 descends for a strike on the piercing element 7. It releases the exhaust holes 45 of the body 15 and the relief channel 41 is then in communication with these exhaust holes 45, which allows the piston 3 to descend without compressing the lower chamber 55 of the cylinder ( Fig. 6 ), then we return to the operating cycle of the figure 1 , piston 3 at the bottom and drawer 19 at the bottom.
