Definitions
- the invention relates to a method for the hydro-erosive rounding of an edge of a component, in particular an edge in a channel of a high-pressure-resistant component, in which a liquid mixed with grinding wheels is guided along the edge to be rounded.
- the invention also relates to the use of the aforementioned method.
- Injection nozzle anticipated aging process, so that this occurs only slightly during operation. In recent years it has been shown that with injectors that have a high degree of efficiency, achieve particularly good emission and performance values. An increase in efficiency can be achieved by a higher degree of rounding.
- washouts can be avoided, for example, by an extrudehone rounding process.
- a grinding paste is pressed through the spray holes. With this grinding process, very high degrees of rounding can be achieved without washing out.
- the disadvantage here is that the flow of the grinding paste cannot be determined during the grinding process, so that the setting of the flow accuracy of the spray holes suffers.
- the injection nozzles have to be laboriously cleaned using this method, so that no residue of the grinding paste remains in the nozzles and their spray holes. Appropriate residues can clog the spray holes or prevent the nozzle from being sealed by the nozzle needle.
- Another known variant for avoiding leaching is to greatly reduce the grinding pressure of the erosive liquid by reducing the flow speed. As a result, the grinding times increase explosively and the quality achieved leaves many wishes unfulfilled.
- high-pressure-resistant injection nozzles for fuels are produced in the area where the guide bore for the nozzle needle and the fuel inlet bore which taper at an acute angle and which open into the guide bore intersect.
- the guide bore is often expanded to create a high-pressure chamber.
- the web-like area of the edge, which is enclosed between the guide bore and the fuel feed bore, is also referred to as a spickle.
- the edge or the spike is known to be a place in which local stress peaks occur under load, which can lead to failure of the injection nozzles.
- the edge In order to make the injection nozzles more pressure-resistant, the edge has to be rounded off with the spatula. Various methods for this are generally known in the prior art.
- the high pressure resistance of the injection nozzle can be increased to approximately 1800 bar.
- Injection nozzles with compressive strengths of more than 1800 bar are rounded on the ax with the help of a paste mixed with abrasive particles.
- the paste is pressed through the fuel inlet bore through the body of the injection nozzle and out of the guide bore.
- This process is also known as extrudehone.
- the injection nozzle has to be cleaned in a complex manner in order to remove the grinding paste remaining in the injection nozzle after rounding.
- the flow rate of the liquid and thus also the material removal in the area of the edge can be influenced by adjusting the delivery pressure.
- the delivery pressures are in the range of 50 bar to 140 bar.
- the direction of flow of the liquid and the longitudinal axis of the edge to be rounded preferably enclose an angle of 90 °.
- the present invention has for its object to provide a method for hydro-erosive rounding of an edge of a component, in particular an edge in a channel of a high-pressure-resistant component, and a use for this, with which an optimization of the rounding result is achieved.
- the liquid has a viscosity in the range from 10 to 100 mmVs, preferably about 50 mmVs.
- the oil can also be dissolved in other oils, such as diesel or diesel-like oils, so that the component is easy to clean after the rounding process. Complex cleaning processes compared to the extrudehone process can be omitted. After the rounding process, it is sufficient to rinse the component with oil to remove any remaining grinding wheels. Disposal is simplified (no hazardous waste) and the high viscosity ensures a homogeneous and stable distribution of the grinding particles over time. Most of the organic oils meet these requirements.
- the grinding times are also considerably reduced, so that cycle times are available which enable the rounding process to be used in series production. The grinding times can be kept specifically low and the roughness to be achieved can be over the delivery pressure, the grinding body concentration and large, the viscosity of the grinding oil and the flow rate of the grinding oil are specifically varied.
- the pressure arising in the liquid is measured and the rounding process when a preselected pressure is reached in the liquid is stopped.
- This method can therefore be used in series production and the desired degree of rounding can be achieved in a targeted manner.
- This type of control is particularly suitable for rounding spray holes in an injection nozzle for fuels. This also makes it easier to adapt this method to the geometric and fluidic conditions of other components.
- the rounding method according to the invention can advantageously be used for components of a fuel injection system in order to increase the high-pressure strength there to over 1800 bar.
- An edge, in particular a spatula, in the intersection region of a fuel inlet bore with a guide bore of an injection nozzle or an edge in the region of the spray hole of an injection nozzle can be considered as the component of the fuel injection system to be rounded.
- FIG. 1 shows a sectional view of a high-pressure-resistant fuel injector
- Figure 2 is a detail enlargement of Figure 2 from the area of the fuel inlet bore of the injection nozzle and
- FIG. 3 is a diagram showing the various grinding oils
- the method according to the invention for the hydro-erosive rounding of edges in high-pressure-resistant components is carried out using a highly viscous liquid mixed with grinding wheels.
- the highly viscous liquids used are abrasive oils with a viscosity in the range from 10 to 100 mm 2 / s, preferably around 50 mm 2 / s.
- it can be a
- FIG. 1 shows a sectional view of a high-pressure-resistant injection nozzle 1 for diesel fuel.
- the overall elongated injection nozzle 1 has a central guide bore 2 for the nozzle needle 3, each of which extends with its longitudinal extension parallel to the longitudinal axis of the injection nozzle 1.
- the nozzle needle 3 is displaceably guided in the longitudinal direction of the guide bore 2 in order to be able to close and uncover the spray holes 4 arranged in the region of a nozzle needle seat at the front end of the injection nozzle 1.
- a fuel inlet bore 5 opens into the guide bore 2 at an acute angle and its longitudinal extension is essentially directed towards the front end of the injection nozzle 1. In the area in which the fuel inlet bore 5 opens into the guide bore 2, the guide bore 2 is expanded to a high-pressure chamber 6.
- FIG. 3 shows an enlarged section of FIG. 2 from the area of the fuel inlet bore 5 of the injection nozzle 1.
- the fuel inlet bore 5, the guide bore 2 and the high-pressure chamber 6 intersect with one another, so that a circumferential edge 7 is created in the course of production.
- the web-like region of the circumferential edge 7, which faces the guide bore 2, is also called an ax 8.
- this edge 7 is rounded off with the spatula 8 by means of a highly viscous liquid 10 mixed with abrasive bodies 9.
- the liquid 10 is introduced into the fuel inlet bore 5 under high pressure and flows through the fuel inlet bore.
- FIG. 3 shows a diagram which, for a standard grinding oil A and two highly viscous grinding oils B and C according to the invention with increasing viscosity in the range from 2 and 100 mm 2 / s, shows the flow coefficient HD of the spray holes 4 (see FIG. 2) over the degree of rounding HE shows.
- Mining oils or synthetic oils are suitable as grinding oils B and C.
- the degree of rounding HE is directly related to the rounding time.
- FIG. 3 it can be clarified that the hydro-erosive grinding process is divided into different phases I to IV. First, in a first phase I, the inlet edge of the spray hole 4 of the injection nozzle 1 is rounded.
- a second phase II the roughness peaks in the spray holes 4 are smoothed, then in a third phase III there is a controlled increase in diameter.
- the spray holes 4 are washed out in an uncontrolled manner. This creates flow channels that lead to a deviation of the Guide the spray holes 4 from the roundness.
- These individual aforementioned phases have a strong effect on the flow coefficient HD of the nozzle 1 with the spray holes 4, which is proportional to the efficiency of the nozzle.
- the efficiency increases in the first two phases, then stagnates in the third phase and then drops again in the fourth phase. This also shows that the maximum efficiency can be influenced by using different grinding oils A, B and C.
- the highly viscous grinding oils B and C according to the invention achieve higher degrees of rounding HE and thus also better flow coefficients F of the injector 1.
- the higher rounding degrees HE also go hand in hand with an improved high pressure resistance of the injection nozzle 1.
- FIG. 3 also shows that the highly viscous grinding oils B and C according to the invention reduce the risk of getting into the phase IV washout range during the grinding process.
- the rounding times can be significantly reduced due to the optimized grinding effect, so that cycle times are achieved which enable this rounding process to be used in series production.
- the hydraulic flow of the grinding liquid during the grinding process can be measured, so that a control and targeted control of the rounding process is possible.
- Two measurement methods can be used for this. First, given the constant volume flow of the grinding fluid, the pressure that arises during the grinding process can be measured. If a desired pressure is reached, the grinding process is ended. To this In this way, the desired target value of the hydraulic flow can be set very precisely.
- the target value for the hydraulic flow is coupled with a target range for a desired rounding degree or flow coefficient.
- the volume flow can be measured at a constant predetermined pressure.
- the grinding process is then ended when a desired volume flow is reached.
- the desired hydraulic flow is set with a corresponding degree of rounding or flow coefficient.
- the former method is preferred because measuring the pressure gives more reliable results.
- the grinding oil in a 1 -Phase flow or 2-phase flow can flow.
- a standard grinding oil in the form of a 2-phase flow can flow during the grinding process, whereas, under the same boundary conditions, a highly viscous grinding oil according to the invention does not cavitate and is present as a 1-phase flow.
- the flow behavior of a 1-phase flow versus a 2-phase flow is very different. This has a decisive impact on the resulting flow coefficient F.
- a two-stage grinding process is advantageous.
- grinding is carried out with a highly viscous liquid up to a definable distance, for example 5% from a target value.
- a target fluid is used to grind to the target value.
- the target fluid corresponds to a test oil that is used to test the hydraulic flow and that contains abrasive particles.
