Definitions
- the invention relates to a method and a device for coating the cylindrical circumference of engine pistons or the like with coating material, in particular lubricating pastes.
- Such a coating of piston surfaces which is usually a lead, tin, graphite or similar coating of a certain thickness, is carried out on pistons in order to prevent the pistons from seizing if the oil lubrication fails in the cylinders of an internal combustion engine also to reduce the knocking of the engine when coating in varying thickness and changing coating pattern.
- the coating of engine pistons has hitherto generally been applied by spraying, which is complex and unsatisfactory due to high losses at low output.
- spraying has a high environmental impact due to the spraying of large amounts of solvents.
- the circumferential surfaces of the pistons are coated with masks during spraying, no sharp contours of the coating surfaces can be achieved.
- the spray mist also causes undefined coating contours underneath the spray masks that do not fit tightly.
- the thickness of the coating which is determined by adjusting the spray nozzle, usually has large tolerances.
- the invention is therefore based on the object of providing a method and a device for coating the cylindrical periphery of engine pistons or the like with coating material, by means of which the aforementioned, previously existing shortcomings are eliminated with relatively simple procedural and structural outlay. It should also be achieved that the required coating thickness can be reproduced at any time based on predetermined values for different pistons.
- This object is achieved in that the coating is carried out by screen printing.
- a uniform coating with the smallest of tolerances can be applied in a rational manner to the cylindrical peripheral surfaces of engine pistons or the like, with any environmentally harmful emissions, such as e.g. solvent evaporation are completely switched off.
- This process can also be used to apply several layers of the same or different thicknesses one above the other in one process sequence. If the viscosity of the coating composition remains the same, the thickness of the coating on the piston peripheral surface can be predetermined via the quality of the fabric of the screen printing stencil.
- one or more uncoated open areas can advantageously also be provided as lubrication pockets and / or as a control window in the form of slots, holes, cutouts, strips or the like in a coated surface.
- Such open spaces serve a double function.
- they can serve as measuring holes or control windows for measuring and thus for checking the coating thickness, and on the other hand, they improve the lubrication of the piston in normal operation, since they act as a lubrication bearing.
- such free areas can be produced in a simple manner and without great effort in any size and design with very precise tolerances with regard to thickness and edge contours. This is especially true for very small open spaces.
- the pistons are expediently printed and rotated about their vertical central longitudinal axis on a screen printing stencil while resting against it, the screen stencil being moved in the direction of rotation of the piston peripheral surface.
- the coating is advantageously applied in a wedge shape at its lateral and / or upper and lower edges with decreasing coating thickness. This measure prevents hard edges or steps and the coated surface runs out smoother. In this way, in particular a better adaptation to the roundness of the piston is achieved and correspondingly strong resistances are avoided. This applies in particular to the lateral edges, but it is also advantageous for the upper and lower edges with regard to the direction of movement of the piston.
- the coating composition can be continuously mixed and fed into the screen printing stencil of the screen printing unit.
- the invention also relates to a device for carrying out the screen printing coating, which is characterized in that it has one or more screen printing stations, each with a screen printing stencil and an application squeegee, on the screen printing template of which the pistons to be coated can be moved into their receptacles with their cylindrical peripheral surface to be coated that the pistons with their receptacles in the advanced position can be rotated about the central longitudinal axes of the pistons, the printing stencil being free to move tangentially to the circumferential surface of the piston tangentially to the latter, and that the application doctor is parallel to it
- the center longitudinal axis of the doctor blade edge, which is to be coated faces the piston circumferential surface which bears against the screen printing stencil during the printing process.
- the pistons can be arranged vertically or horizontally.
- the screen printing stencil and the application doctor extend vertically and that the pistons are arranged vertically on the receptacles.
- the doctor blade hardness can be adapted to the desired thickness of the coating to be applied. If several screen printing stations arranged one behind the other on the path of the pistons to be coated are provided, the doctor blades of these stations can have the same or different hardness.
- the pistons 1 which are fed in a standing manner by means of a continuously rotating conveyor belt 15 with their central longitudinal axis X, are removed from the conveyor belt and cyclically by a rotary head 16 with pliers 17, which grip the pistons 1 in their grooves with jaws (not shown) a gear satellite system 9, 12A, 12B, 14A, 14B pass position-controlled receptacles 18, which are arranged on a turntable 13.
- the pistons 1 are held in a rotationally fixed manner by upwardly projecting mandrels 6, on which the pistons 1 are placed, and they are rotated by rotating the rotary table 13 at three screen printing stations A, B and C one behind the other by a step switching device are introduced, in which they receive the predetermined coatings A1, B1, C1 one after the other on their cylindrical surface.
- These coatings are applied by means of screen printing stencils 2, which come into tangential contact with the piston peripheral surface to be coated by means of application doctor blades 10.
- the pistons, together with their receptacles 18, are subjected to a rotation about their central longitudinal axis X (FIGS.
- the printing stencil 2 being able to move tangentially to the circumferential surface of the piston without sliding.
- the arrows in Fig. 2 show the direction of rotation and direction of movement of the piston peripheral surface and the screen printing stencil 2 during the printing process.
- the application doctor blade 10 remains with its doctor blade edge, which extends parallel to the central longitudinal axis X of the piston 1 to be coated, opposite the piston circumferential surface resting on the screen printing stencil, and thereby applies the coating compound supplied to the upper region of the screen printing stencil via a hose 8 through the stencil onto the piston circumferential surface .
- the piston 1 is provided on its piston head with a circumferential coating C3 by the screen printing station C and in the region of the piston circumference only on the sides offset to the piston pin bore 3 with coatings for coating surfaces A1, B1, C1 by the Coating stations A, B, C have been provided.
- the coating surfaces shown in the exemplary embodiment are of course only mentioned for example. In many cases, fewer coating areas will be sufficient. For example, only two lower coating surfaces A1 can be provided, which are opposite each other and each extend over a circumferential area of approximately 90 °. The two coating areas A1 can e.g. be provided as a buffer for reducing engine knock and have a coating thickness of 10 ⁇ m.
- two coating surfaces C1 which are likewise arranged opposite one another and are arranged at a distance and parallel to the coating surfaces A1 and possibly also B1, can be provided in particular for emergency lubrication in the event of normal oil lubrication failing.
- the coating surfaces C1 (and possibly B1) can also extend over a circumferential area of 90 ° in each case and have e.g. a thickness of 20 ⁇ m.
- the coating surfaces A1, B1 and C1 run out in a wedge shape 4 at their edges.
- the coating areas can be provided with small uncoated open areas 5.
- rectangular, elliptical and round recesses 5 are drawn in principle in the coating surfaces A1 and C1.
- other coating areas can also be provided with corresponding open areas, for example in the form of holes, slots, strips, ellipses, ovals, circles or the like.
- the viscosity of the coating material should be in the range of 6,000 - 8,500 cp. Very good results can be achieved with a viscosity of approx. 7,000 cp.
- Isopropanol or ethyl glycol have been found to adjust and, if necessary, change the viscosity.
- the excess coating compound running off the screen printing stencil is collected in a storage trough 11 located underneath the template and mixed again by means of a pump 7 via a hose line 8 and fed back to the screen printing stencil.
- the tendency of the coating composition to change its viscosity due to disintegration is counteracted by the mixing and continuous feeding of the screen printing composition.
- the doctor blade 10 is withdrawn from the screen printing stencil 2, causing it to come out of contact with the coated piston peripheral surface, so that the screen printing stencil can be moved back into its tangential starting position by the piston without contact.
