Definitions

  • the invention relates to a method for producing a spherical cap in a valve needle of a valve according to the preamble of claim 1.
  • a tip of a plunger element for a pressure control valve with a recess for contacting a valve ball before the valve is installed.
  • the recess has two areas with different curvatures arranged concentrically around the center axis of the tappet element: In a first inner area the valve ball can be moved in the radial direction, while in a second outer area the valve ball can be moved in the radial and axial directions. No axial effects are effective within an existing radial play, so that the noise behavior is improved.
  • the spherical valve closing element serves as an embossing body in the embossing process to be carried out, which serves to introduce a spherical cap in the area of an end face of the anchor pin.
  • the anchor pin is subjected to an stamping force acting axially in the direction of the valve seat, so that the spherical valve closing element causes a plastic deformation of the anchor pin in the area of the end face, the dome being formed.
  • the valve seat and the spherical valve-closing element used therein are previously aligned coaxially to the longitudinal axis of the anchor pin.
  • an anchor pin is used, the end face of which is already provided with a depression, so that the depth of the dome and thus the stamping force to be applied can be reduced.
  • a solenoid valve with a valve housing which has a central recess enclosed by a solenoid, in which a Magnet armature guided displaceably and a magnet core is fixedly arranged, with a plunger acted upon by force in the closing direction by the magnet armature, which is guided displaceably in a guide hole of the valve housing and at one end of which a shut-off body in the form of a ball is arranged, which opens from the plunger in the closing direction a valve seat of a valve passage is acted upon.
  • an anti-rotation element is arranged on the end region of the plunger on the magnet housing side.
  • Both a dome and a spherical contour of the valve seat are created in that the ball is pressed onto the valve seat by means of the plunger, so that the ball, which is made of a harder material, is embossed into the plunger, which is made of softer material, and the dome is embossed into the the component having the valve seat, the spherical contour of the valve seat is generated. This compensates for manufacturing tolerances in the valve components and creates absolute coaxiality between the ball and the valve seat.
  • valve with a valve needle is known, the valve needle being provided with a ball which is applied to a seat by the valve needle.
  • the end of the valve needle is provided with an imprint with a shallow ball guide depth. The impression is achieved by applying an axial force against a sealing ball in the valve seat, which ensures the formation of a concave ball cap at the end of the needle.
  • the DE 10 2011 012 548 A1 shows a method for producing a valve, wherein in a first method step a valve with a valve chamber and a valve body movably arranged within this valve chamber is made available and the valve body rests against a sealing seat in a switching position of the valve so that the valve body has a first sealing surface of the valve and the sealing seat forms a second sealing surface of the valve that interacts at least temporarily with the first, at least one of the sealing surfaces being made of a plastic and at least one sealing surface being tempered to match the sealing surfaces to one another.
  • the sealing surfaces are at least temporarily pressed against one another during the tempering of the sealing surface and / or after the tempering.
  • the object of the present invention is to reduce acoustic abnormalities of a valve with a valve needle and to improve the embossing process.
  • this object is achieved by a method for producing a spherical cap in a valve needle with the features according to claim 1.
  • Advantageous further developments of the invention are characterized in the dependent claims.
  • the features listed individually in the patent claims can be combined with one another in a technologically meaningful manner and can be supplemented by explanatory facts from the description and / or details from the figures, further design variants of the invention being shown as defined in the appended claims.
  • a spherical cap is produced in a valve needle of a valve.
  • the valve has a valve seat, a sealing ball, a needle guide and the valve needle with a needle tip.
  • a space between the valve seat and the sealing ball forms a valve gap and the needle guide supports the valve needle so that it can move axially.
  • the sealing ball and the valve needle in particular also the valve seat and the needle guide, are provided.
  • a spherical cap for contacting the sealing ball is created in the needle tip.
  • the spherical cap is shaped in that the spherical cap is at least partially impressed by a force action of the sealing ball, in particular an actively excited or applied force action of the sealing ball.
  • the dome is in particular a hollow or dome-shaped depression.
  • the valve seat is preferably conical.
  • the valve seat, sealing ball, needle guide and valve needle are components of the valve.
  • the valve can comprise further components.
  • the valve can have an electromechanical actuator for moving the valve needle.
  • the electromechanical actuator comprises an armature and a pole core.
  • the pole core can be a valve body or part of a valve body.
  • the at least partial embossing can be a final embossing.
  • the spherical cap is particularly preferably completely embossed and / or produced by the sealing ball, in particular in one or more embossing steps.
  • the action of force is not an action of force due to use of the valve, for example due to wear during operation of the valve.
  • the action of force is preferably greater than the action of the forces occurring during operation, in particular normal or normal operation, of the valve.
  • the needle tip in particular the dome, can be preprocessed.
  • the embossing may include deepening a pre-machined recess.
  • the pre-machined recess can be spherical cap-shaped.
  • the pre-machined recess preferably has a smaller radius of curvature than the sealing ball.
  • the spherical cap in the needle tip can be stamped individually for each individual valve by the sealing ball used individually in the valve, so that manufacturing and / or assembly-related tolerances can be individually taken into account or compensated for. As a result, acoustic abnormalities are reduced during operation.
  • the valve seat, the sealing ball, the valve needle and the needle guide are assembled in the method according to the invention before the dome is at least partially stamped, even before the dome is generated.
  • the at least partial, preferably complete embossing of the dome according to the invention - and possibly also the production of the dome - takes place in the assembled state of the components influencing the accuracy in the valve.
  • the contacting, the guidance, and the positioning of the sealing ball are individually centered in the valve, so that radial differences in the effect of forces on the sealing ball during operation are reduced, preferably completely avoided.
  • the embossed depth of the dome and / or a residual air gap between an armature and a pole core of the valve is preferred in the method according to the invention Embossing checked. If the embossed depth is not yet equal to the intended depth and / or the residual air gap is still greater than the intended value, the embossing is repeated in a further or in several further steps until the intended depth is reached and / or until the residual air gap is intended Has value. This ensures a high level of precision in the embossing process.
  • a valve characteristic curve can be determined in the method according to the invention after the embossing.
  • the determined valve characteristic can be compared with a target characteristic.
  • the embossing can be canceled or continued in one or more embossing steps.
  • a valve with a desired opening behavior of the valve gap can be obtained. So that the relative movement of the components is not undesirably influenced, in particular so that no undesired damping or disturbance of the movement occurs when the sealing ball is vibrated, it is particularly useful in the method according to the invention if no working fluids are present in one or more spaces between components of the valve during embossing and / or one or more spaces between components of the valve are evacuated. In this way, less or no fluid forces act.
  • the valve needle is secured against twisting in the needle guide by a form fit and / or a force fit.
  • the azimuthal position of the valve needle and sealing ball is fixed to one another during the embossing process, so that the embossing can take place precisely.

  • the valve is preferably a high pressure regulating valve for a fuel system in an internal combustion engine.
  • the components valve seat, sealing ball, valve needle with needle tip and needle guide and further components of the valve, in particular for its electromechanical actuator, are provided in a step 10.
  • the needle tip has a pre-machined dome which has a smaller radius of curvature than the sealing ball.
  • the valve is mounted so far that the electromechanical actuator can move the valve needle axially in the needle guide during its operation.
  • the spherical cap is embossed, in particular finely embossed, by means of a force action of the sealing ball.
  • the edge of the dome is embossed on the surface of the needle tip.
  • the sealing ball is excited to vibrate with the intention of embossing in such a way that the sealing ball exerts the force on the needle tip.
  • the material composition of the provided components sealing ball, valve seat and needle tip takes into account that the sealing ball has a greater hardness than the valve seat and this in turn has a greater hardness than the needle tip.
  • the effective length of the valve needle is reduced.
  • the remaining air gap when the valve is completely closed directly determines the steepness of the electro-hydraulic valve characteristic and the electronic control parameters.
  • the remaining air gap or the valve characteristic must be taken into account and checked during the embossing process.
  • the sequence shown in the preferred embodiment of the method according to the invention determines in a step 16 the valve characteristic obtained after the embossing in step 14. If the valve characteristic is flatter than a desired characteristic, the stamping step is repeated at a suitable time (step 18) until the actual characteristic matches the desired characteristic.
  • FIG. 2 is an enlarged schematic of a needle tip of a valve needle touching a sealing ball in two partial images A and B before and after the embossing according to the invention, in particular in the preferred embodiment as with reference to FIG Figure 1 explained.
  • partial image A the situation is shown in which the sealing ball 32 and the needle tip 40 of the valve needle 28 contact each other in an annular circle contact 42:
  • a recess in the form of a spherical cap 26 is pre-processed.
  • the radius of curvature of the dome 26 is significantly smaller than the radius of curvature of the sealing ball 32.
  • the width of a residual air gap between the pole core and armature of the electromechanical actuator of the valve is greater than a nominal width.
  • the electromechanical actuator of the valve is operated with a harmonic alternating current during the embossing, without that a liquid, e.g. fuel, is in the valve.
  • the frequency of the alternating current is selected in such a way that the spring-force-loaded armature contacting the valve needle is subjected to mechanical vibrations with the valve needle, whereby maximum forces can be generated in the axial direction. Due to the different hardnesses of the components involved, the sealing ball is impressed into the dome, with any de-axing being compensated at the same time. In this way, the ring circle contact 42 of partial image A becomes an annular surface contact 44, as shown in partial image B.
  • the same components are provided with the same reference numbers in the two partial figures.
  • the dome is embossed in several steps: In one embossing step, only partial deformation is carried out. Then the current characteristic curve of the partially waved valve is determined. As long as the current actual characteristic does not yet match the target characteristic with the desired precision, the embossing is repeated with a further partial deformation.
  • the embossing is ended.
  • a spherical cap with optimized, preferably optimal lateral guidance of the sealing ball is obtained, so that acoustic abnormalities are reduced, preferably avoided.
  • FIG. 3 shows arranged components of an embodiment of a valve 24 with which a preferred embodiment of the method according to the invention for producing a spherical cap 26 is carried out.
  • a sealing ball 32 and a valve seat 30 form a valve gap 36 upstream of a valve outlet 46.
  • the sealing ball 32 is pressed against the valve seat 30 in the axial direction 38 with the aid of the valve needle 28 axially mounted in a needle guide 34.
  • the end face of the armature 48 is deformed during the embossing according to the invention, for example that the valve needle 28 digs into the end face of the armature 48, the end face can be hardened or provided with a hard inlet.
  • valve 24 In order to be able to utilize the resonance capability of the valve 24, it is particularly advantageous to carry out the embossing according to the invention without filling the valve with fluid, especially in the case of a high-pressure control valve with fuel or test oil. Since a fluid in the armature space changes the vibration behavior, in particular can have a damping effect, a significantly higher energy supply from outside is required with a filling than without a filling. As a function of the specific geometries and process parameters of certain embodiments, a mechanical resonance oscillation can no longer be represented in the presence of fluid. The valve 24 can therefore be filled with air during the method according to the invention or be in the evacuated state.
  • valve is not yet fully assembled.
  • the essential components that are used for embossing are already assembled: valve seat, sealing ball and valve needle in needle guide.
  • a tool 56 in this embodiment a steel body, is brought into the position of the anchor.
  • This tool 56 has a recess 58 which engages over the valve needle 28.
  • the height of the recess is such that after the embossing and the shortening of the valve needle 28 that occurs in the process, the residual air gap 54 arises between the armature and the pole body 50 with the coil 52.
  • the length of the valve needle 28 in the original state determines the strength of the fine embossing on the dome.
  • the valve needle 28 In the state before the embossing of the dome, the valve needle 28 is too long and the current remaining air gap too large.
  • the tool 56 By means of a pressing force 60 acting on the valve seat in the axial direction of the valve needle, the tool 56 is now moved up to the mechanical stop on the pole core 50.
  • the sealing ball is further impressed in the dome of the needle tip so that surface contact is created between the sealing ball and the needle tip (see part B of Figure 2 ).
  • the forces and materials are selected so that only one deformation takes place on the dome.
  • the remaining air gap achieved is also checked in this alternative embodiment by checking the current characteristic curve achieved after embossing. One or more replicas are carried out until the target characteristic is reached. If the valve needle is overprinted, i.e. shorter than a minimum threshold, the valve must be rejected. Alternatively, the remaining air gap can be measured purely mechanically and used as a criterion for limiting the embossing depth.
  • the armature of the electromechanical actuator itself can be used in another embodiment. After each embossing, the remaining air gap must be measured and embossing must be repeated until the target value for the remaining air gap is reached.
  • the valve in a further development the valve, more precisely the needle tip of the valve needle, can be heated in a targeted manner in order to suitably support plastic deformation of the needle tip.
  • a further settlement behavior on the dome during operation is advantageously anticipated.
  • a high-pressure control valve produced according to the invention can be used in particular in a common rail fuel supply of an engine, in particular a diesel engine.
