Abstract
Disclosed is a method for coating a rotationally symmetrical hollow element. In said method, a coating material is applied to the surface to be coated by means of a distribution device. The following successive steps are repeatedly carried out until the surface has been entirely coated: - the distribution device is moved in a linear direction relative to the hollow element; - the distribution device is rotated about a defined angle relative to the hollow element.
Description
The present invention relates to be used for hollow body is carried out the equipment of coating.
In order on member, to form high-quality surface, often will be to its coating in addition.At this, with a kind of material by usually only for the thin layer of several μ m is coated on the support element, so as to for example improving its wear strength, perhaps give component surface specific character (as electroconductibility).
Known have a various coating process, wherein particularly adopts the hot coating method, by this method, with the coated material fusing, utilizes pressurized air or other air-flow to be atomized then usually, and be transported on the surface for the treatment of coating earlier.Known hot coating method has plasma-coated, (at a high speed) flame plating and the spraying of arc wire material.
DE 19841617A1 has introduced a kind of arc wire material spraying equipment that is used for hollow body is carried out coating.
Disclosed arc wire material spraying equipment has the burner bar that is the tubular shaft form in this patent document, and it is inserted in the cavity of desiring coating.On the lower end of burner bar, disposed a nozzle, by this nozzle, by means of the coated material molten drop of fusing being discharged by the hollow cavity compressed and supplied air of burner bar according to radial location.
Above the burner bar, there is a feeding mechanism of being furnished with two silk material volumes to be fixed thereon.Roll out from the silk material and to send out, two silk materials be parallel to the burner bar longitudinal center line be directed into the tip of this burner bar.There, by electric high pressure, produce an electric arc between two silk material terminations, this electric arc melts the silk material.The molten drop of the silk material that is melted is compressed airflow then and catches, and by nozzle it is discharged.Feeding mechanism is responsible for nozzle and supplies with coated material continuously.
In coating procedure, the burner bar is driven in rotation constantly, and moves in hollow body by straight line simultaneously.By the stack of these two kinds of motions, produce a kind of spiral layer process that is coated with.
The shortcoming of the device that proposes among the DE 19841617A1 is that structure is very complicated, and this is relevant with following situation: the whole unit of being made up of burner bar and feeding mechanism must constantly and be in and (be generally 100 to 150 rpms) under the high speed conditions and be driven in rotation.
In addition, also known from prior art, replace rotation to drive the burner bar, hollow body itself is driven rotatably.This situation is little, light and rotation hollow body of design symmetrically particularly for those, and it is suitable to have proved, can not produce big unbalance in rotary course.For complexity and non-rotating symmetric member, for example for cylinder block crankshaft case, this setup will accomplish that the member balance but has very big trouble.For cylinder block crankshaft case, also have a where the shoe pinches to be exactly, cylinder block crankshaft case all has the cylinder body of a plurality of in addition coatings usually, wherein also must change rotation to each cylinder body, so just need make the unit rebulid balance.
Therefore,, the purpose of this invention is to provide a kind of improved method and a kind of improved equipment, be used for hollow body is carried out coating, wherein, can eliminate at least one from shortcoming known in the art from prior art.Particularly should provide such equipment, it can realize comparatively simply constructing in the design.
Above-mentioned purpose is achieved by the described method and apparatus of independent claim.Favourable form of implementation is the theme of each dependent claims.
Design of the present invention is: the coating of hollow body no longer is by the helically execution with straight-line stack that rotatablely moves, but realize by a kind of rhythmical translational motion.
Therefore, the present invention's regulation: at first in first linearly extended zone coating is carried out on the surface of desiring coating, wherein, the distribution device of coated material and hollow body straight line relative to each other move.For this reason, disposed at least one linear drive apparatus,, made distribution device and/or hollow body translational motion, thereby they are moved relative to each other by this linear drive apparatus according to the present invention.After reaching the stroke end (the trip terminal point is normally defined by the terminal that reaches the straight line extension for the treatment of coatingsurface), in next step, distribution device is with respect to definite angle of hollow body rotation, wherein, this rotation is preferably carried out around the straight-line axis of before having implemented.For this reason, disposed at least one rotating driving device for distribution device and/or hollow body.
After definite angle of rotation, can in second section, carry out coating to the surface of desiring coating, for this reason, implement a kind of straight line relative movement of distribution device again to hollow body.This can distribution device with respect to the return movement process of hollow body in thereby be achieved against travel direction when carrying out first section coating exactly.Perhaps, distribution device also can return idlely, that is does not discharge coated material on the outlet side of hollow body, and the coating of second section be one continue after stroke in be achieved by the direction identical with preceding primary coating stroke.In this way, just can obtain coating as required, this coating was just implemented by same direction of motion originally.
Distribution device with respect to the idle translational motion of hollow body according to the present invention can be before rotatablely moving, among or carry out afterwards.
So constantly repeat above-mentioned method steps, obtain handling up to the whole surface of coating for the treatment of, wherein, this surface might not be continuous fully, and by rhythmic ground coating is arranged, those not in addition the surface segment of coating also can be skipped over simply.
The respective design of the control device by rotating driving device can select to make two section overlaids that priority is coated arbitrarily.Overlapping by corresponding size also can obtain a kind of multiwalled coating in a coating procedure.
Linear drive apparatus and/or rotating driving device can drive distribution device and/or hollow body directly or indirectly.Particularly can stipulate: be stationary installation of hollow body configuration, hollow body reliably and is accurately located by means of this stationary installation.If for making the hollow body motion dispose linear drive apparatus and/or rotating driving device, then this point also can be achieved by following manner: stationary installation is moved by drive unit, and drive unit guiding going along with location hollow body thereon.
According to an advantageous forms of implementation of the present invention, linear drive apparatus is as diaxon or the design of triple axle linear drive apparatus.This just makes distribution device except the collinear to-and-fro movement, can also be at another or move on the both direction in addition, and wherein, these two or three directions are preferably each other in oriented at right angles.By this design of equipment of the present invention, distribution device and treat that distance between the surface of coating can be adjusted to for coating and handle the degree that speech is the best, and often must consider the eccentric position of distribution device in hollow body here.It is very debatable that this situation is died owing to the lasting rotation of distribution device or hollow body is in equipment as known from the prior art, because can produce a continually varying distance between maximum value and minimum value, this distance has only the very complicated measure of using just can be compensated, and has then obviously realized this compensation more simply in the equipment that the present invention proposes.To this, described distance just just must be proofreaied and correct in distribution device has rhythm to rotate with respect to hollow body process.And particularly be parallel in the coating procedure that moves on the hollow body surface at distribution device, this compensation is unwanted.
Certainly, the linear drive apparatus of diaxon or triple axle can be made up of some single parts, these parts spatially with all be can be separated on the structure, but preferably control by a central control unit.
With reference to the embodiment shown in the accompanying drawings the present invention is elaborated below.
