Description
Technical field
The present invention relates to a kind of block sandwich type element of hydraulic equipment of motor vehicle braking system, it is separated from the extrudate of clavate by means of separation process, wherein, block sandwich type element is configured with two parting surfaces respect to one another.In addition, the present invention relates to a kind of method for the manufacture of this piece of sandwich type element.
Background technique
Hydraulic equipment uses in a motor vehicle, in such as passenger car or load truck, for the retardation pressure providing adjustment at its motor vehicle braking system place.Thus, achieve particularly the function of anti-lock braking system (ABS) and/or Electronic Stability Program (ESP) (ESP).For this reason, such hydraulic equipment generally includes with the valve of the pump of multiple pump piston, multiple Electromagnetic Control, for controlling the controller of described valve and the motor for making pump piston move.At this, pump piston is accommodated in block sandwich type element or so-called hydraulic block, and it is such as described together with relevant manufacture method in document DE 10 2,009 026 417 A1 and document DE 10 2,010 062 270 A1.
Traditionally, single block sandwich type element or pump case is formed with aluminium.In addition, pump case arranges relevant controller and the motor of subordinate on an interface respectively.Not only controller but also motor are made up of the material of iron or iron content usually at this, and must at least be provided with passive or erosion-resisting protective layer at these jointings and be made up of stainless steel.Otherwise due to electrochemical voltage effect, occur contact corrosion between aluminium and iron, it particularly causes the so-called pit corrosion at pump case place.
Summary of the invention
According to the present invention, realize a kind of block sandwich type element of hydraulic equipment of motor vehicle braking system, it is separated from the extrudate of clavate by means of separation process, wherein, is configured with two parting surfaces respect to one another at block sandwich type element place.At this, at least one in parting surface is provided with anodic oxide coating.
Anodic oxide coating is particularly interpreted as the layer be made up of the aluminium of electrolytic oxidation, and wherein, anodic oxidation is the abbreviation of the electrolytic oxidation of aluminium.The aluminium of electrolytic oxidation by means of at the converting one-tenth oxide of metal layer containing aluminium of block sandwich type element the topmost part or hydroxide, is preferably formed by means of its anodic oxygen changes into oxide or hydroxide.Trivalent aluminium oxide (the Al so formed in final effect by oxidizing process
2o
3) do not pulled on as layer, but produce by means of the oxidation of the aluminium lamination of the topmost part and thus serve as especially stable oxide protective layer.As long as there is not space in oxide protective layer, the darker layer of such oxide protective layer protection aluminium is not corroded.In addition, this oxide protective layer or anodic oxide coating extremely hard (about Mohs hardness 9) and corrosion-resistant, and achieve correspondingly hard and corrosion resistant high-quality especially parting surface.
Be arranged to be used as the building blocks of function in hydraulic equipment, in particular for the motor drive shaft holding at least one pump piston He make at least one pump piston move according to of the present invention piece of sandwich type element or pump case self.
In addition, according to the present invention advantageously, the conjunction plane of at least one parting surface described as other building blocks of function, particularly motor and/or the controller for connecting hydraulic equipment of anodic oxide coating is provided with.Thus, certainly other building blocks of function that can connect or arrange hydraulic equipment is at parting surface.So arrange, achieve especially corrosion resistant conjunction plane for other building blocks of function or interface by the anodic oxide coating on parting surface, and there is not the risk of contact corrosion at this.Contact corrosion derives from the different standard electrode potential within the electrochemistry electromotive series of the different materials participating in component.Particularly, there is-1.66V as the aluminium (Al of normal potential E °
3+/ Al) particularly electronegative, and thus usually than other material used most, such as there is-0.04V as the iron (Fe of normal potential E °
3+/ Fe) and alloy more in electronegativity.More mean at this in electronegativity, compared with other material be touched, such as iron, aluminium trends towards discharging electronics more.Now, have on the block sandwich type element of aluminium if be arranged in by the building blocks of function be fabricated from iron, then aluminium will discharge electronics to iron, and occur contact corrosion, particularly so-called pit corrosion.Thus, in moisture possibility infiltrate briquetting, this may cause the inefficacy of whole hydraulic equipment and then whole braking system.
In order to overcome such contact corrosion, when manufacturing with aluminium, traditional Interface design becomes to have coating that is expensive, passivation, such as zinc-nickel-alloy or the stainless steel by means of application of expensive and realizes.These measures are as secondary measure and usually carry out on other building blocks of function.Compared with the interface manufactured with this tradition, the advantage that the parting surface on block sandwich type element according to the present invention has is, utilizes anodic oxide coating to make block sandwich type element self be passivation at this.Thus, form at least one protective layer when not have the cost of material of adding at block sandwich type element from the ground of cost-effective with it, it is corrosion resistant especially in addition.
In addition, the present invention also relates to a kind of hydraulic equipment for motor vehicle braking system, it comprises according to the block sandwich type element as building blocks of function of the present invention and at least one the other building blocks of function being connected in this place.At this, at least one other building blocks of function described is preferably motor and/or controller.
Preferably, in extrusion process, particularly expressing technique, manufacture the extrudate of clavate with aluminium, make the block sandwich type element be separated at least at least one parting surface, be formed with aluminium.Particularly preferably, the extrudate of whole clavate and then whole piece of sandwich type element are formed with aluminium simply especially in processing technique.Forming with aluminium like this to make block sandwich type element be formed according to anodic oxide coating of the present invention at least one parting surface.
According to the present invention, anodic oxide coating is preferably particularly being formed in the separation process that makes block sandwich type element and be separated from clavate extrudate by means of wire cutting technology in addition.Thus, such anodic oxide coating is at least one parting surface described simultaneously, thus block sandwich type element is cost-effectively not only separated but also has been provided with corrosion protection portion at least one parting surface described in an operation from extrudate.Particularly, formed at this anodic oxide coating by wire cutting technology, thus, achieve the block sandwich type element accurately formed especially, its shape and surface no longer need to continue processing.In addition, this surface self passivation.
The cutting process of the normally accurate especially thermal etching for conductive material of wire cutting technology, it is based on as the discharge process between the electrode of instrument and the workpiece of conduction.This discharge process is called as spark, and this technique is called as the processing of spark erosion or spark erosion.In the cutting of spark erosion, galvanic corrosion line is guided through the workpiece being arranged in non-conductive medium, so-called insulating medium continuously as electrode.At this, by means of voltage pulse produce spark, its make material from workpiece be delivered to through galvanic corrosion line and be delivered in insulating medium.Single spark always just jumps to the minimum position of the spacing of workpiece and galvanic corrosion line, thus achieves very high cutting accuracy.At this, melt to spark point-like and evaporate the material of workpiece.Different erosion results is produced according to the intensity of discharging, frequency, endurance, length, gap width and polarity.Usually, instrument has positive charge and workpiece has negative charge.Thus, produce electro transfer, the electronics that is producing workpiece in this case moves from workpiece to the direction of galvanic corrosion line and insulating medium, thus corrodes at workpiece place generating material.
According to the present invention, in favourable wire cutting technology, the clavate extrudate with aluminium is preferably used especially preferably to use deionized water as insulating medium as workpiece.Thus, at electricity consumption corrosion line cutting extruded profile sections or when making block sandwich type element be separated, the parting surface abutting in its both sides forms aluminium oxide layers anodic oxide coating in other words simultaneously.The single parting surface of such formation constructs to obtain especially flat and accurately.
In addition, according to the present invention, anodic oxide coating advantageously generates 1 micron of thickness to 16 microns, particularly 2 micron to 8 microns.Thus, while high corrosion resistance, thickness little is especially realized.By this very little thickness, the few especially material of the block sandwich type element consumption formed thus is for anodic oxide coating, and it can be used for other function, such as holding reciprocating pump.Generally speaking, special joint space-efficient block sandwich type element is thus achieved.
In addition, according to the present invention, single parting surface advantageously has surface structure coarse equably, and it does not have continuous print rill or striped.This parting surface can special become simple ground and can utilize little sealed width sealing, as the interface of other building blocks of function.On the other hand, traditional interface due to processing reason there is continuous print thin striped in its surface.This striped is formed due to following reason during course of working, that is, traditional interface is formed by means of the milling process at hydraulic block place or the compressive surface directly by being formed when manufacturing extrudate is formed.Such striped is difficult to sealing and needs seal, because Sealing must invade in each striped completely to avoid the effect of Sealing by striped institute seepage failure with high cost.For this reason, need the Sealing with corresponding large sealed width, so, this also defines the extension size of block sandwich type element.
According to the present invention, when advantageously generate in addition according at least one parting surface of the present invention be less than 10 microns, be preferably less than 9 microns and be especially preferably less than the roughness of 8 microns time, achieve sealed width little especially.At this, roughness is the tolerance of the surface roughness of single parting surface, because of but the tolerance of its surface irregularity.Roughness be surface, particularly perpendicular to the maximum value of the extension on the surface of parting surface plane and the difference of minimum value.Preferably, multiple positions measurement roughness from the teeth outwards, to obtain mean value R
z, mean roughness.By roughness according to the present invention, single parting surface has the uniform especially surface structure of roughness.Thus, this parting surface has very large bond area, and other component, particularly building blocks of function can bond on parting surface simply by high bonding effect or adhesion especially.Preferably, roughness has 3 microns, the particularly preferably minimum value of 5 microns for this reason.Can be gathered in the recess formed thus for bonding tackiness agent, and realize stable bonding effect.
In addition, on block sandwich type element two parting surfaces respect to one another according to the present invention be advantageously designed to have lower than 0.10 millimeter, be preferably lower than the separation tolerance of 0.03 millimeter.This separation tolerance is the difference between the minimum and ultimate range between two parting surfaces respect to one another.The separation tolerance little especially according to the present invention means at this, that is, two parting surfaces respect to one another are almost parallel to each other.Accurately form parting surface especially thus, this simplify the subsequent installation of block sandwich type element in hydraulic equipment.If two parting surface flat functional accomplishing controller and each interface to motor, then ensure that flat functional relative to each other extra high precision.
In addition, according to the present invention, advantageously impulse-free robustness ground manufactures at least one parting surface described.Carrot-free parting surface achieves utilization area large as far as possible as the conjunction plane at block sandwich type element place, and it can be used for connecting or installing other component, particularly building blocks of function and/or also for sealing purpose.In addition, the burr do not stretched out, otherwise this burr has the risk damaged.
In addition, at least one parting surface described is preferably designed so that flat according to the present invention and additionally provides king-sized utilization area thus as the conjunction plane for connecting other component, particularly building blocks of function.
In addition, the present invention correspondingly also relates to a kind of method of block sandwich type element of the hydraulic equipment for the manufacture of motor vehicle braking system, it has following steps: the extrudate providing clavate, and by means of separation process, at least one block sandwich type element is separated from clavate extrudate, wherein, use wire cutting technology as separation process.According to the present invention, by the wire cutting technology described, make full use of its precision to manufacture block sandwich type element, this block sandwich type element can very accurately be made when other not required traditionally process step thus.Meanwhile, compared with traditional separating technology, such as sawing, during separation process, obviously consume the material of less clavate extrudate by means of described galvanic corrosion line.The saw blade used when sawing has the thickness of about 3 millimeters usually, and galvanic corrosion line used according to the invention preferably only has the diameter of about 0.2 millimeter.
According to the present invention, advantageously, at least one in addition in cutting on line technique simultaneously in the parting surface produced of block sandwich type element forms anodic oxide coating.That is, in an operation, from extrudate, not only isolate accurate block sandwich type element, and at least one in parting surface has been provided with passivation or erosion-resisting anodic oxide coating.Thus, save time and materials, and in industry processes, achieve the cycle short especially.
In addition, 1 micron of thickness to 16 microns, particularly 2 micron to 8 microns is preferably configured with according to anodic oxide coating of the present invention.This little thickness special rapidly and accurately formed by wire cutting technology according to the present invention simultaneously.
In addition, in cutting on line technique, according to the present invention advantageously, at least one in the parting surface produced of block sandwich type element is formed and is less than 10 microns, is preferably less than 9 microns and is particularly preferably less than roughness and/or the impulse-free robustness of 8 microns.This roughness can be made simply by natively accurate wire cutting technology especially, and forms following so single parting surface, that is, other component can be installed (particularly bonding) especially simply and be sealed in this parting surface place.Particularly preferably, according to the present invention in separation method, particularly by means of wire cutting technology, made single parting surface in addition impulse-free robustness.Thus, deburring afterwards necessary in traditional separation method can be saved, thus achieving cycle time short especially according in of the present invention piece of sandwich type element manufacture.
In addition, two, block sandwich type element place parting surface respect to one another according to the present invention be advantageously designed to have described lower than 0.10 millimeter, be preferably lower than the separation tolerance of 0.03 millimeter.At this, two relative parting surfaces can be used as motor port and control unit interface or solenoid valve interface (MV interface) immediately.Two parting surfaces form side thus, can load onto the Packed motor of tool and the Packed controller of the tool solenoid valve together with controller place at this side place.Thus, especially with the mode of saving work and cost eliminate afterwards otherwise the surface Machining of the block sandwich type element of necessity and/or cutting.
Preferably according to the present invention, from clavate extrudate, isolate multiple pieces of sandwich type elements in cutting on line technique in addition simultaneously.At this, it is so-called multiple cutting process, wherein, in an operation simultaneously at multiple position by the extrudate as the separation member line galvanic corrosion Linear cut clavate in other words of electrode in other words.Thus, very fast and economically block sandwich type element can be produced in enormous quantities.Advantageously, the separation member having an especially little loss by application in addition, as separation member, also improves Economy.

Embodiment
Fig. 1 shows the clavate extrudate 10 containing aluminium, and it obtains in extrusion process or expressing technique by means of unshowned extrusion press from aluminium bar material.From clavate extrudate 10, saw lower block 12 at a right angle relative to the direction of extrusion 11, it is used as the matrix of block sandwich type element.Thus, produce the first saw face 14 and the relative second saw face 16, it is extruded face 18, second and extrudes face 20, the 3rd with first and extrude face 22 and the 4th and extrude the block 12 forming square body shape together with face 24.In addition, when sawing, the face of extruding 18 to 24 produces burr 25 on its each side, these burrs must remove in method step after a while.Not only saw face 14 and 16 but also extrude face 18 to 24 and be formed as all containing block 12 boundary surface (Fig. 2) having aluminium.
Block 12, after other process step, is arranged in another unshowned hydraulic equipment of motor vehicle braking system as building blocks of function in method step after a while as block sandwich type element.For this reason, the face of extruding that needs two are relative is as the conjunction plane for connecting other building blocks of function after a while or interface.At this, extrude face 18 and be used as the interface of motor 26 and extrude the interface that face 22 is used as controller 27.At this, extrude face 18 and 22 for two and there is the surface being provided with continuous print rill, so-called processing trace 28 equably, its when extruding due to processing conditions produce (Fig. 3).When installing motor 26 and controller 27, must seal this continuous print processing trace 28 with such sealed width respectively, that is, such sealed width can realize, and relevant Sealing invades in processing trace 28 completely.Thus, the effect of Sealing should be avoided to be permeated by this processing trace 28 seepage failure, so-called sealing.
In addition, block 12 in the face of extruding 18,20, there is between 22 and 24 seamed edge with radius 29 of the rounding according to processing.This radius 29 is determined by the mould with the extruder of approximate rectangular cross section used in an extrusion process, and the bight of its cross section is with radius 29 rounding.By this mould, compacting and/or pull-out aluminium bar material, thus, form the clavate extrudate 10 with rounded edge forcibly, this rounded edge has radius 29.Radius 29 or drawing radius determine thus first extrude face 18 and the 3rd extrude on face 22 operational as interface for installing the size in the face of other component, especially building blocks of function.Radius 29 is larger, then the plane that adversely can be used as interface is less.And purely from the advantage relative with this shortcoming processing technique be achieve correspondingly long tool life by relatively large radius 29.
In addition, not only motor 26 but also controller 27 are especially made up of the material of iron or iron content.The protective layer of the coated passivation in surface of motor 26 and controller 27, such as zinc-nickel-alloy.Thus, the aluminium generation contact corrosion of anti-stops sandwich type element or block 12 is comparatively expensive traditionally.
In Fig. 4 to 6, extrudate 10 that formed by aluminium, clavate have passed through according to separation method of the present invention as the aluminium bar of extruding.As material, use AlMg at this
3mnSi
4as aluminum alloy.At this, carried out the multiple cutting process of Linear cut as separation method, wherein, multiple galvanic corrosion line is guided through the extrudate 10 of clavate in the mode at a right angle relative to the direction of extrusion 11 as instrument (not shown).At this, isolate multiple block or block sandwich type element 30 with high precision simultaneously.When being separated, produce two parting surfaces 32 and 34 in the instrument both sides passed respectively, it is formed as carrot-free and has coarse uniform surface.Two relative parting surfaces 32 and 34 surround four faces of extruding 36,38,40 and 42 between it respectively in each block formula or block shape housing 30 place, and these faces of extruding do not have burr thus.Thus, the deburring of high cost is after a while eliminated.
In the face of extruding 36,38, there is the rounded edge with radius 43 between 40 and 42, it produces as already described in an extrusion process.But in a solution in accordance with the invention compared with the block 12 manufactured in a conventional manner, this radius 43 only has an impact using insignificant very little degree to the face as interface for installing other building blocks of function.According to the present invention, arrange at least one in two parting surfaces 32 and/or 34 as interface or conjunction plane, described parting surface only sentences radius 43 rounding in its bight.Thus, achieve such block sandwich type element 30, that is, when parting surface 32 or 34 has identical outside dimension, it has the utilization area larger than traditional block 12 as interface, and this traditional block 12 is extruded face 18 or 22 at it and is on each two relative sides and has rounded edge.Such rounding make there face can not as utilization area flat as far as possible for use (Fig. 5 and Fig. 2 compares).Therefore, parting surface 32 and 34 also can harmlessly have than the in this case larger radius 43 at known radius 29 at its bight place.By this larger radius 43, cost-effectively achieve tool life longer in extrusion process.
Therefore, with reference to individual interface, it is different from traditional radius 29 that radius 43 is positioned at.Its reason is, compared with traditional block 12, with reference to individual interface, and the direction of extrusion 11 or extrude direction change.In tradition, the direction of extrusion 11 is parallel to the individual interface being formed with the face of extruding 18 or 22 and stretches.According to the present invention, the individual interface formed with respect to parting surface 32 and 34 in this direction of extrusion 11 stretches at a right angle.The direction of extrusion 11 so changed just can be realized by means of the wire cutting technology carried out according to the present invention.Thus, achieve carrot-free parting surface 32 and 34, it need not deburring or processed by other surface finish, but can be used as interface immediately.
In addition two parting surfaces 32 and 34 have been formed with the anodic oxide coating 44 of the thickness 46 of 2 to 8 microns respectively in separation method in instrument both sides to be invaded.The anodic oxide coating 44 of formation like this is interpreted as the trivalent aluminium oxide (Al formed by means of electrochemical conversion by the aluminium lamination of the topmost part of extrudate 10
2o
3), and do not pulled on as layer.Therefore, anodic oxide coating 44 is permanently connected especially with the aluminium of block sandwich type element 30, and defines the protection portion preventing aluminium from corroding reliably in addition, protects in particular relative to the contact corrosion described.Thus, utilize according to of the present invention piece of sandwich type element 30, one of them is installed motor 26 and controller 27 as other building blocks of functions at parting surface 32 and 34 respectively, and it costly need not protect these other building blocks of functions not by contact corrosion.
There is according to the coarse uniform surface of anodic oxide coating 44 of the present invention the roughness R being less than 10 microns, average about 7.1 microns
z48.In addition, the cutter trade of the systematize sensing being such as continuous wave pattern or strip form is there is not at this.There is no continuous print striped due to roughness 48, achieve such parting surface 32 or 34, that is, can especially simply and arrange with little sealed width and seal other component, especially building blocks of function at such parting surface place.Especially advantageously, thus can simply with high adhesion other component bonding, because can be gathered in roughness 48 for the glue of this corresponding viscosity used.
Meanwhile, it is parallel to each other in other words that parting surface 32 and 34 has approximately uniform distance, because it to realize with the separation tolerance of very little about 0.03mm thus with very high dimensional accuracy.Thus, that the parting surface 32 and 34 with anodic oxide coating 44 is doomed to be used as accurately to be formed, for the functional surfaces of the motor 26 and controller 27 that connect hydraulic equipment or interface.For this reason, even can provide the interface for controller when the reference processing not in motor-side, thus, save material and eliminate follow-up cutting temporally.
In unshowned enforcement flexible program, the extrudate 10 of clavate has foursquare cross section, by means of wire cutting technology make at least one dish type, block sandwich type element 30 is from wherein isolating.Such piece of sandwich type element 30 has two foursquare parting surfaces 32 and 34, and it is due to its foursquare shape, saves material and add building site to be no longer necessary for following process and to make marks.
