Definitions

  • the present invention relates to the field of flame cutting torches.
  • torches known so far include a nozzle having a cutting hole and several heating orifices.
  • the cutting hole ensures bringing the cutting oxygen current to the workpiece, and the heating orifices allow the room to be heated to be cut by combustion of a combustible gas in the heating oxygen.
  • documents DE-A-14 29 136, FR-A-444 349, DE-C-249 170, DE-B-12 09 973 and FR-E-9375 we can also refer to document US-A-3,934,818 which illustrates an oxygen cutting torch equipped a cooling system allowing to project a air / water mixture whose composition is adjustable.
  • the invention aims precisely to solve this problem, designing oxygen cutting equipment that is both robust to guarantee accuracy over time despite the thermal constraints of the environment, also allowing simple, practical and fast maintenance to take into account production requirements, while authorizing manufacturing and operating costs optimized, as well as reduced intervention times minimum.
  • the object of the invention is therefore to produce a flame cutting torch which simultaneously presents the advantages of high precision, long service life, and ease of disassembly.
  • an oxygen cutting torch comprising an element of support made from a non-deformable block of material machinable with precision, said support element including integrated supply lines for gaseous fluids heater and filler and coolant, and a heating element permanently fixed against a lower face of the support element, said heating element being made from a solid block in which are provided passages for gaseous fluids and fluid which communicate directly with the corresponding pipes of the support element, as well that at least one nozzle precisely positioned in two coaxial bores respectively provided in the element of support and the heating element, said nozzle being connected to a cutting oxygen supply line and opening at the free face of the element of heated.
  • the torch includes an element holding ensuring precise positioning of the nozzle, said element passing through an associated bore of the element of support and coming to cap the part of the nozzle which is in said support member.
  • the element of holding cap the nozzle by a terminal bore thereof which is connected to a support shoulder cooperating with the upstream edge of the nozzle, which nozzle has externally a support shoulder against the element of heated.
  • the holding element is fixed on the support element by a fixing means rapid, and said holding element further has a inlet bore associated with pipe connection cutting oxygen supply.
  • the pipes and the coolant passages are arranged for pass in the vicinity of the nozzle. So the circuit of coolant, which is common to the element of base and heating element, ensures a regime stable thermal for the cutting oxygen nozzle (s) integrated into the mechanical assembly as well regularly cooled.
  • the support element is in stainless steel and copper heating element, the the nozzle being made of a suitable material such as copper, brass or ceramic.
  • Figures 1 and 2 show a blowtorch of oxygen cutting C mainly comprising an element of support noted 10 to which is permanently fixed at least one heating element noted 20.
  • the support element 10 here has a branch vertical connection 11 and a substantially insole horizontal 12.
  • This monobloc assembly is made from a non-deformable block of material that can be machined with precision, for example stainless steel.
  • Branch 11 has holes 13 for fixing the flame cutting torch C on a positioning device, which can by example be constituted by an articulated system.
  • Some number of pipes marked 14.1 to 14.5 are fitted in upper part of branch 11 of support element 10. We find here a set of five lines, but it goes without saying that the invention is not limited to a number particular of such conducts.
  • the conduct 14.1 corresponds to a coolant inlet, for example water
  • line 14.2 corresponds to a supply gas
  • line 14.3 corresponds to a heating oxygen supply
  • line 14.4 corresponds to a supply of heating gas
  • the line 14.5 corresponds to an outlet of the cooling.
  • Each of these pipes is overcome a tip, noted respectively 15.1 to 15.5 allowing a connection to external pipes not shown here.
  • All of these supply lines gaseous heating and supply fluid and liquid cooling extends inside the element of support 10 by passages which have not been shown here, and which open at the level of the lower face denoted 19 of the sole 12 at the outlet orifices respectively noted 16.1 to 16.5 visible in Figure 2. In this sense, the aforementioned pipes are integrated into the support element 10.
  • a heating element, noted 20 is attached to remains, here by three screws 17, against the underside 19 of the support element 10.
  • This heating element 20 is made from a solid block, for example copper, in which passages 21, 22, 24, 27 are provided for gaseous heating and filler fluids and cooling, which communicate directly with the corresponding pipes of the support element 10.
  • the passages 21 correspond to the cooling circuit by water
  • the passages 22 correspond to the gas input, which gas passes through associated channels for open through orifices 23 at the free face denoted 28 of the heating element 20.
  • the passages 24 correspond to the heating gas, which comes out of the heating element through associated channels 25 opening out at the level of orifices 26.
  • the passages 27 correspond to the heating oxygen, which passes through small associated channels 27 'connecting to the aforementioned channels 25.
  • the aforementioned output channels are arranged conically around a central axis X which is the axis of a nozzle which will be described later.
  • Ports 23 and 26 are arranged in two concentric circles, around the nozzle outlet.
  • the flame cutting torch C furthermore comprises minus a nozzle 30 better visible on the sectional section of Figure 1.
  • This nozzle 30 is completely classic connected to a 14.6 supply line cutting oxygen, and it opens through an orifice 31 at the level of the free face 28 of the heating element 20.
  • the positioning of the nozzle 30 is on the other hand completely original, and it allows for calibration extremely precise of the X axis of the nozzle with respect to the support element 10 which is a non-deformable block.
  • the nozzle 30 is generally positioned precisely in two coaxial bores 41, 32 respectively provided in the support element 10 and the element of heats 20.
  • the nozzle passes directly in the bore 32 of the heating element 20, but that on the other hand it is not in direct contact with the bore 41 formed in the support element 10.
  • a holding element, noted 40 passing in this bore 41 of the support element 10, which element 40 covers the part of the nozzle 30 which is in the support element 10. More specifically, the element holding 40 covers the nozzle 30 by a terminal bore 42 thereof which is connected to a noted support shoulder 43 cooperating with the upstream edge of the nozzle 30.
  • the part (here upper) of the nozzle 30 which is inside of the support element 10 is thus exactly positioned in the associated bore 42 of the element 40, which element is exactly positioned in bore 41 of said support member.
  • the nozzle 30 also has an outwardly marked support shoulder 33 against the heating element 20, that is to say in the present case against the upper face 29 of said heating element.
  • a seal 48 seals for cutting oxygen arriving via line 14.6 surmounted by its nozzle of connection 15.6.
  • a seal 50 is also provided for sealing between the widened part of the element 40 and the upper face 18 of the sole 12 of the element support 10.
  • the holding element 40 also has an inlet bore marked 44 associated with the connection of the line 14.6 for cutting oxygen supply.
  • the use of such a holding element guarantees very high accuracy for positioning the nozzle 30.
  • the cooling circuit which is common to the support element 10 and the element of heater 20
  • excellent protection is obtained temperature of the nozzle 30 which is thus surrounded on its entire outer surface by an assembly maintained at a homogeneous temperature, which guarantees longevity superior.
  • the free face 28 of this element represents a cold surface even during operation of the flame cutting torch, so that the any slag which is projected in the liquid state does not can adhere against this surface, unlike unprotected traditional heating elements against direct soldering of projected slag.
  • the aforementioned holding element 40 is fixed on the element support 10 by a quick fixing means.
  • a pin screw or a grasshopper as a means quick fixing device which can be operated without tools.
  • a rapid fixation has been shown by means a cylindrical head screw 45 which is screwed into a associated tapping 46 of the sole 12 of the element support 10, the head 45 passing through a semi-circular notch denoted 49 of element 40.
  • the associated pin passing through a lateral bore of the head 45 is denoted 47.
  • nozzle 30 will preferably be produced in a suitable material such as copper, brass or ceramic. To perfect the cooling of the nozzle, it will be advantageous to provide that the pipes and the holes of coolant are arranged to pass to the vicinity of the nozzle 30. In the present case, if one refers in the top view of FIG.
  • the stainless steel support element simultaneously allows the machine to machine a connection very precise mechanics, remaining undeformable including shock, while serving as a fluid distributor concerned with the different elements themselves solidly and very precisely attached to this support element.
  • the element heating will consist of one or more burners (the figures show a burner variant unique, but this is of course only an example). Cooling by the common water circuit that of the support element allows the heating element to withstand large differences without damage temperature and, as said above, at possible splashes of liquid slag occurring during "misfires" of cutting.
  • At least one independent cutting oxygen nozzle is used, being practically “drowned” in the mass of the support element in one or more housings associated with very precise mechanical positioning by with respect to the connection machining of the support element. This or these nozzles thus remain at the temperature constant of the cooled whole, which allows moreover to preserve despite the thermal constraints of the environment, their manufacturing precision and therefore their performance.
