Definitions
- the invention relates to a metering valve for viscous materials according to the preamble of claim 1.
- Such metering valves designed as needle valves are known and are used, for example, in the automotive industry for applying adhesives, sealants, insulating materials or thermal compounds to body components. They are characterized by the fact that they can be precisely controlled by means of suitable actuators and opened and closed again within a short time, so that even small quantities of the viscous material can be reliably applied to the workpieces. If a plurality of material outlet openings and associated valve needles are arranged in a row in order to allow the simultaneous application of a plurality of mutually parallel material beads, then the material outlet openings can not be arranged arbitrarily close to one another.
- the distance between the material outlet openings to each other is limited downwards by the diameter of the valve needles and by a minimum distance of the valve needles to each other, the latter by the need for precise guidance of the valve needles and a leakage of the viscous material between the valve needle and the housing preventing seal results. It is therefore an object of the invention to develop a metering valve of the type mentioned in such a way that with him material caterpillars or points with less Diameter and / or less mutual distance can be applied.
- the inventive solution according to claim 1 is based on the idea to achieve a sufficiently stable, precise and well-sealed leadership of the valve needles by forming the valve needles and the leadership of the valve needles made of carbide, so that they can be kept small and arranged at short distances from each other ,
- the arrangement of the material outlet openings at small distances from one another and the possibility of equipping the material outlet openings with a small cross section result from an arrangement of the valve needles at small distances from each other.
- the guide block is adapted with high precision to the valve needle or the valve needles, which is or are received in it with almost no play. This measure also causes a very accurate guidance of the valve needle or the valve needles.
- the invention according to claim 12 is based on the idea that components made of hard metal are more resistant to wear. It is therefore advantageous to form the valve needle or the valve needles made of hard metal, since carbide is chemically resistant in particular to the materials to whose application the metering valve is used. If the valve needles are made of hard metal, the associated valve seats can not be made of softer material, as they would otherwise be deformed by the valve needles. Both aspects of the invention can advantageously be combined with each other, wherein the valve seats are expediently arranged on a valve seat block.
- a cemented carbide is to be understood as meaning a metal matrix composite material in which hard materials present in particulate form are held together by a matrix of metal.
- the hard materials used are, in particular, metal carbides or metal nitrides, for example tungsten carbide, titanium carbide, titanium nitride, nickel carbide, tantalum carbide or vanadium carbide.
- both aspects of the invention defined by claims 1 and 12 are combined with one another, wherein the valve seat block and / or the guide block is expediently made in one piece from hard metal and preferably from the same hard metal as the valve needles, which simplifies production.
- the housing expediently has a supply line through which the material channel runs from a material inlet opening to the valve seat block.
- the Zulei- tion part is preferably made of stainless steel or aluminum and in particular in one piece. Stainless steel and aluminum are cheaper, less brittle and easier to machine than carbide.
- the guide block is expediently received in the supply line part and preferably detachably connected to it.
- a flushing chamber for receiving a fluid is expediently arranged on the rear side of the guide block facing away from the valve seat block. This may include softener properties that prevent particles of viscous material passing through the guide block from hardening, setting or caking there.
- a fluid which is sold under the trade name Mesamoll or Mesamoll II is particularly suitable as the fluid. It is suitably passed through a supply line and a drain in the housing through the washing chamber, so that it is constantly flushed with the fluid.
- the housing is a closure part which is connected to the supply line and is preferably made of stainless steel or aluminum and which has or covers the rinsing chamber, which also expediently has the supply line and the discharge line at least in sections.
- the housing is formed in several parts with a plurality of housing parts, of which at least two are detachably connected to each other.
- One of the detachably interconnected housing parts is the guide block and / or the valve seat block and / or the Zu effetsgeil and / or the closure part. If one of the housing parts detachably connected to other housing parts is worn, it can be exchanged in a simple manner, without the entire metering valve having to be replaced. This advantageously relates to the housing parts made of hard metal.
- a plurality of material outlet openings and a plurality of valve needles are each arranged in one row or in a plurality of rows preferably running parallel to one another.
- the valve needles may have a small diameter, so that the valve seats and the material outlet openings can be made correspondingly small.
- the metering valve can have a plurality of small material openings which are arranged at a small distance from one another and over which small amounts of material in the form of a thin bead of material or in the form of small material points can be applied to the workpieces with high precision.
- an actuator unit with at least one actuator, preferably at least one piezoactuator.
- the connection of a valve needle made of hard metal to an acted upon by an actuator actuator of another material is not trivial.
- the connection is expediently by soldering.
- sleeves connected to adjacent valve needles are advantageously arranged at different distances from the respective valve seat. This takes into account the fact that the sleeves naturally have a larger diameter than the valve needles, but must not collide during operation.
- each of the pods is then acted upon by the actuator unit, wherein expediently between each sleeve and the actuator unit, a solid-state joint is arranged.
- This can then be connected in particular by means of laser welding to the sleeve.
- each valve needle is associated with an actuator to its admission. It is also possible for each valve needle to be acted upon by at least one elastic return element mounted in the housing in a direction away from the respective valve seat with a force against which the actuator unit applies a closing force.
- the loading preferably takes place via a solid-body joint, which, however, need not be rigidly connected to the relevant valve needle, but can rest loosely on it in order to press it against the valve seat.
- the at least one restoring element preferably engages in each case on a shoulder of the valve needles, wherein the shoulders of adjacent valve needles can be arranged at equal distances from the respective valve seat, but are expediently arranged at different distances from the respective valve seat.
- a material drainage channel which communicates with the material channel and which leads to a material discharge opening is arranged in the housing.
- a material flow can then take place, so that the material duct is always flushed with material.
- a Peltier element for tempering the viscous material is arranged on or in the housing, in particular on or in the supply part. The Peltier element can heat and cool the viscous material and can for example be inserted into a recess on the edge of the housing or placed on the housing.
- a material outlet channel extends between each of the valve seats and the associated material outlet opening.
- Nal whose central axis with respect to the longitudinal axis of the associated valve needle, along which it is movable between the closed position and the open position, is angled at an acute angle.
- the acute angle is expediently between 10 ° and 40 ° and preferably approximately 20 °.
- the center axes of all material outlet channels run parallel to each other. It is further preferred that the center axes of all material outlet channels extend transversely to a plane spanned by the longitudinal axes of the valve needles.
- the material outlet openings are arranged in a material outlet surface and the center axes of the material outlet channels are perpendicular to the material exit surface.
- the metering valve is moved at a distance parallel to the workpiece surface, preferably in the direction in which the central axis (es) of the material outlet channel or the material outlet channels is angled relative to the longitudinal axis of the respectively associated valve needle . are.
