Definitions

  • the subject of the present invention is the manufacture of washing or spraying ramps, in particular for equipping all types of washing machines, these washing ramps being designed so as to solve all the problems of sprinkling, sprinkling , soaking, takeoff, and all similar problems.
  • the washing ramp is produced in the form of a tube 10, which is drilled with cylindrical holes such as 12, which can be milled (12 ′, Fig. 2) on the 'outside.
  • the holes 12 or 12 ' are drilled from the outside towards the inside of the tube.
  • the watering boom is also in the form of a tube 10 having holes in which are screwed sprayers or spray nozzles 14, which may have different shapes depending on the desired applications .
  • the present invention proposes to provide a method of manufacturing washing or dispersion ramps which does not have the drawbacks of known solutions.
  • the invention relates to washing or spraying ramps of variable length, comprising one or more jets, these ramps being intended to equip any type of washing machine, and more particularly washing machines for industrial equipment, and to resolve the problems with spraying, soaking and taking off, etc.
  • the subject of this invention is a process for the manufacture of washing or spraying ramps, characterized in that it consists in starting from a tube which can be machined, in milling in the thickness of said tube a chamfer, the angle at the apex is between 25 and 60 °, at the point where it is desired to obtain a jet, to drill a hole in the wall opposite to that where said chamfer has been milled, then to machine, opposite said chamfer, a second chamfer with an angle at the apex of between 90 and 150 °, this second chamfer opening through the tube in the first chamfer, so as to produce an elliptical opening whose surface increases as the distance which separates the vertices of the angles of the first and second chamfer increases, the hole which is drilled in the wall opposite to said elliptical opening being filled, preferably by welding.
  • the method according to the invention consists in starting from a tube which can be made of very diverse materials, such as, in particular: steel, stainless steel, copper, graphite, etc.
  • the thickness of the tube is preferably equal to or greater than 4 mm.
  • the method according to the present invention essentially comprises two steps:
  • a chamfer 18 is cut through the thickness of the tube 10, having an apex angle b whose value is between 25 and 60 °, and preferably equal to 45 °.
  • the chamfer thus produced can be local and arranged opposite each jet, the length of the chamfer d (that is to say the dimension between the outer edge of the tube and the top of the angle b) making it possible to obtain the desired opening.
  • the chamfer 18 can be produced over the entire thickness of the tube, without departing from the scope of the present invention, this variant not causing any modification in the efficiency of the jets finally obtained.
  • the apex angle a of the same bisector as the angle b, has a value between 90 and 150 °, and preferably equal to 120 °.
  • an opening is thus produced which is obtained by the meeting of the chamfers 18 and 20, this opening having the shape of an ellipse 24 (FIG. 5), the surface of which increases as the distance between the vertices of angles a and b. in Figure 4, this distance is represented by the difference between dimension d and dimension c.
  • the diameter e which corresponds to the diameter of the hole 22, varies as a function of the diameter and the thickness of the tube, in order to obtain the dimension h, that is to say the length of the cylindrical part on which the chamfer 20 opens.
  • the references f and g designate respectively the width and the length of the ellipse 24.
  • the hole 22 is filled in, preferably by welding, in order to avoid attachment points.
  • Figures 6 to 8 show the shape of the elliptical jets obtained using a ramp produced according to the method of the invention.
