Definitions

  • the invention relates to an application nozzle for applying a viscous material to workpieces according to the preamble of claim 1.
  • Such application nozzles also known as flat stream nozzles, are used to generate a wide spray jet, for example to apply a paint to seal seams or an insulating material that has to be applied flat to a workpiece.
  • Such application nozzles are used in particular for coating body components for the automotive industry, but also for coating components of other devices such as built-in devices for kitchens.
  • the application channel widens towards the material outlet in a first spatial direction, in which the width of the application nozzle is measured, which is usually several times (e.g. 5 to 10 times) larger than that in a second Spatial direction measured perpendicular to the first spatial direction thickness of the nozzle body.
  • the nozzle body is mounted on a nozzle holder through which extends a feed channel through which the material is fed into the application channel.
  • the nozzle body is detachably fixed to the nozzle holder, with the nozzle holder having two clamping plates in previously known application nozzles, which abut opposite side surfaces of the nozzle body and clamp it in a gap formed between them.
  • a clamping plate is in one piece with the feed channel having main body of the nozzle holder connected, while the other clamping plate is releasably fixed to this and the nozzle body.
  • the invention is based on the idea that by designing the two clamping plates as separate components and releasably fixing them to the base body and the nozzle body, the edges delimiting the space between the clamping plates intended to accommodate the nozzle body can be designed as sharp edges as possible with a small radius that the nozzle body can be easily fitted between the clamping plates and that there is a high degree of tightness at the transition from the base body to the nozzle body.
  • the tightness is further improved if, according to the invention, the side surfaces of the nozzle body are inclined toward one another at an acute angle, starting from the base body, this angle preferably being a maximum of 30° and in particular a maximum of 10°. Due to the fact that the clamping surfaces of the clamping plates resting on the side surfaces, starting from the base body, are in the same If the angles run towards one another, they press the nozzle body against the base body when it is clamped.
  • the side surfaces each extend up to an end region which protrudes from the intermediate space between the two clamping parts and has the material outlet, at which end region the thickness of the nozzle body increases.
  • a greater thickness of the nozzle body in the area of the material outlet increases its stability, so that it is mechanically more resistant to mechanical loads, such as during cleaning.
  • the end region can be designed as a shoulder projecting from the side surfaces on both sides.
  • the clamping plates each lie flat with a clamping surface on one of the side surfaces of the nozzle body. This achieves a good clamping effect.
  • the clamping plates each have a groove in which a part of the base body is accommodated. This facilitates the positioning of the clamping plates in relation to the base body.
  • the clamping plates and the nozzle body are expediently fixed to one another by means of at least one screw and/or at least one pin. This represents a particularly simple type of attachment.
  • the nozzle body is preferably made of hard metal.
  • a hard metal is to be understood as meaning a metal matrix composite material in which the hard materials present in particle form are held together by a metal matrix.
  • metal carbides or metal nitrides such as tungsten carbide, titanium carbide, titanium nitride, niobium carbide, tantalum carbide or vanadium carbide, are used as hard materials.
  • Carbide is a more expensive material than metal. However, it is much more durable and wear-resistant, especially with regard to abrasive viscous materials.
  • the nozzle body has two nozzle plates lying flat against one another, between which at least one section of the application channel is located.
  • the nozzle plates are advantageous loosely to each other and are pressed against each other by means of the clamping plates. It is possible for one of the nozzle plates to have a depression forming the application channel, while the other nozzle plate is ground flat and the depression only covers the application channel, limiting it on one side. However, it is preferred that both nozzle plates are structurally identical.
  • each of the nozzle plates on the side facing the other nozzle plate, has a delimiting surface that delimits the application channel at least in sections, a shoulder protruding from the delimiting surface with a first contact surface that rests on the other nozzle plate and is parallel to the delimiting surface, and a flat adjoining the delimiting surface has a second contact surface against which the first contact surface of the other nozzle plate rests.
  • This solution according to the invention according to independent claim 10 offers the advantage that the nozzle body is easier to manufacture, particularly when it is made of hard metal. In this case, it is preferred that the nozzle plates bear against one another on contact surfaces to which the second spatial direction extends transversely and preferably perpendicularly.
  • the nozzle plates are advantageously made in one piece and preferably made of hard metal.
  • the application channel has a first section extending from the material inlet and delimited on two sides by the clamping plates and a second section extending to the material outlet and surrounded by the nozzle body.
  • the application channel widens only in its second section in the first spatial direction.
  • the first section also widens in the first spatial direction, starting from the material inlet towards the second section.
  • the nozzle plates can be easily manufactured from hard metal plates. A cutout to form the first section of the application channel is cut out of the hard metal plate by eroding or cutting, and the boundary surface and the second contact surface are then produced by grinding along an edge bounding the shoulder. Only they have to Contact surfaces and the surfaces delimiting the application channel are ground, while grinding the side surfaces of the nozzle body facing away from one another can be omitted.
  • the sealing element is made in one piece from a thermoplastic material, preferably from polyoxymethylene (POM) or polytetrafluoroethylene (PTFE).
  • the sealing element has an outlet gap opening into the second section, the width of which, measured in the first spatial direction, is several times larger than its thickness, measured in the second spatial direction.
  • the thickness of the exit slit is expediently at most twice the thickness of the second section measured in the second spatial direction and is preferably approximately the same in the sense that it differs from the thickness of the second section by at most 10%.
  • the application nozzle 10 shown in the drawing according to the first exemplary embodiment has a nozzle body 12 through which an application channel 14 for viscous material extends from a material inlet 16 to a material outlet 18 .
  • the nozzle body 12 is detachably mounted on a nozzle holder 20 which has a base body 22 through which a feed channel 24 for the viscous material extends to a feed opening 26 .
  • the nozzle body 12 sits on a surface 28 of the base body 22 in which the feed opening 26 is located, the feed opening 26 communicating with the material inlet 16 in such a way that the feed channel 24 opens into the application channel 14 at the feed opening 26 .
  • the nozzle holder 20 also has two clamping plates 30 whose clamping surfaces 32 facing one another bear against side surfaces 34 of the nozzle body 12 facing away from one another and hold the nozzle body 12 in a space 36 between the clamping plates 30 in a clamping manner.
  • each of the clamping plates 30 has a groove 38 in which a portion 40 of the base body 22 is accommodated, which is delimited at the top by the surface 28.
  • Screw openings 42 extend through the nozzle body 12 and the clamping plates 30, through which screws are passed, with which the clamping plates 30 are braced with the nozzle body 12, so that the clamping surfaces 32 are pressed against the side surfaces 34. Additional screws 43 fix the in Fig.
  • the nozzle body 12 has a width b that is significantly greater than its thickness d, which is measured in a second spatial direction 46 perpendicular to the first spatial direction 44 .
  • the application channel 14 has a first section 48 which extends from the material inlet 16 and is open towards the side surfaces 34 and is sealed on both sides by the clamping surfaces 32 .
  • a second section 50 of the application channel 14 adjoins the first section 48 and extends to the material outlet 18 .
  • Both sections 48, 50 of the application channel 14 widen towards the material outlet 18 in the first spatial direction 44, as in particular in FIG Figure 3a shown. The widening takes place with a constant opening angle, starting almost from the material inlet 16 .
  • the applicator nozzle 10 achieves a wide spray pattern with a small thickness when applying a viscous material to a workpiece.
  • the two side surfaces 34 do not run parallel to one another, but rather, starting from the base body 22 , towards one another at an acute angle of approximately 8°.
  • the edges of all components can be precisely ground so that they can be precisely joined to the nozzle body 12.
  • a thickened end region 52 of the nozzle body 12 protrudes upwards from the intermediate space 36 facing away from the base body 22 .
  • the material outlet 18 is located in this end region 52.
  • the nozzle body 12 is composed of two identical nozzle plates 54, each of which is made in one piece from hard metal ( Figures 4a to 4c ).
  • Each of the nozzle plates 54 is machined from a plate-shaped blank made of cemented carbide.
  • an open-edged cutout 56 partially forming the material inlet 16 and the first section 48 of the application channel 14 is eroded or cutting introduced into the blank.
  • the blank is ground down along an edge 58 on one side so that a shoulder 60 remains.
  • the paragraph 60 has a first contact surface 62 .
  • the shoulder 60 is followed by a boundary surface 64 which runs parallel to the first bearing surface 62 and bounds the second section 50 of the application channel 14 on one side.
  • a second contact surface 66 adjoins the boundary surface 64 and is coplanar with it.
  • Two identical nozzle plates 44 are placed loosely against one another to form the nozzle body 12 in that the first contact surface 62 of one nozzle plate 54 rests flat against the second contact surface 66 of the other nozzle plate 54 and vice versa.
  • the second section 50 of the application channel 14 is then located between the two boundary surfaces 64.
  • the nozzle plates 54 are fixed to one another by means of the clamping plates 30 and the screws.
  • the application nozzle 110 according to the second embodiment differs from the application nozzle 10 according to the first exemplary embodiment in only one detail, apart from its size and geometry. Identical features are therefore provided with the same reference symbols in the drawing and are no longer described separately. While in the first exemplary embodiment the application channel 14 and the feed channel 24 are sealed in the area of the feed opening 26 by sealing contact between the nozzle plates 54, the clamping plates 30 and the base body 22, in the second exemplary embodiment the first section 48 of the application channel, which is also shown here also has a constant width in the first spatial direction 44 over its entire length, and an end section of the feed channel 24 that opens into the first section 48 is lined by means of a sealing element 70 made of a thermoplastic material.
  • the sealing element bears against the nozzle body 12, the base body 22 and the clamping plates 30 all around and ensures improved sealing in this area.
  • the sealing element 70 has an outlet gap 72 that opens into the second section 50 of the application channel, the thickness of which, measured in the first spatial direction 44, is approximately as large as the thickness of the application channel 14 defined by the distance between the boundary surfaces 64.
  • the invention relates to an application nozzle 10 for applying a viscous material to workpieces, having a nozzle body 12 through which an application channel 14 extends from a material inlet 16 to a material outlet 18, with the nozzle body 12 having a width in a first spatial direction 44 b, which is greater than a thickness d measured in a second spatial direction 46 running perpendicularly to the first spatial direction 44, and wherein the application channel 14 widens toward the material outlet 18 in the first spatial direction 44, and with a nozzle holder 20, which has a base body 22 and two clamping plates 30, with a feed channel 24 for the viscous material extending through the base body 22, which feed channel 24 opens into the material inlet 16 at a feed opening 26, and wherein the clamping plates 30 resting on opposite side surfaces 34 of the nozzle body 12 detachably detach the nozzle body 12 to the base body 22.
  • both clamping plates 30 are designed as separate components and are detachably fixed to the base body 22 and the nozzle body 12 and/or the nozzle body 12 has two nozzle plates 54 lying flat against one another, between which at least one section 50 of the application channel 14 is located.
