Definitions
- the present invention relates to a forging process for producing a piston or a piston stem.
- the invention also relates to a piston stem produced by this method and to a forging apparatus for carrying out the method.
- Known pistons are usually made cylindrical in a region of the piston crown in order to be able to close the space for the combustion taking place in an internal combustion engine.
- the pin bosses for receiving a piston pin with respect.
- the diameter of the piston skirt are set back inwards. Due to this circumstance, material can be saved in the outer regions and thus a weight reduction can be achieved.
- Shaft wall sections prevent in particular unwanted tilting about the pin axis in the top and bottom dead center.
- the two shank wall sections or the two shank walls are connected via box walls, which contain the piston pin bosses.
- From EP 0 838 587 B2 is a piston with shaft walls and this
- the form engraving in this case has an outer mold ring, a lower mandrel, through which a lower ejector is actuated and an upper mandrel, through which an upper ejector is actuated, wherein in the engraving of the upper mandrel a negative extension cone is provided.
- the mold is closed and the preform is formed by pressing the mandrels to each other, wherein by a combined actuation of the ejector and simultaneous opening of the mold, an ejection of the finished forged piston can take place.
- the present invention is concerned with the problem of providing an improved method for forging a piston skirt, with which, in particular, a weight-reduced piston with inclined box walls can be manufactured comparatively easily and thus economically.
- the present invention is based on the general idea
- Forging method for producing a piston skirt form two stages, being forged in a first stage with a first forging punch and in a subsequent second stage with a second forging punch.
- the piston skirt has, in a known manner, two skirt walls and two box walls connecting these skirt walls.
- the shaft walls can bend or widen conically outwards. A small expansion is required for better molding.
- the box walls are deformed such that their hub outer side substantially parallel to the piston axis or slightly open to the outside and the hub inner side to the free end out to the outside.
- the shank walls are simultaneously drawn into a position which is preferably parallel to the piston axis.
- Hub outside runs according to the Schmiedschrägen downwardly inside obliquely shaped, while the hub inner side approximately parallel to
- Piston axis that is in the present case substantially perpendicular.
- shank area ie the shank walls
- the increasing diameter does not refer to the wall thickness, but to the conical orientation of the
- the piston inner mold is at least in one
- inventive method comparatively simple and thus can be produced economically.
- the piston skirt is forged from an aluminum alloy and then annealed and / or tempered, in particular subjected to a T7 heat treatment.
- targeted heat treatments such as the Tempering or solution annealing can additionally increase the mechanical properties, in particular of aluminum materials.
- the principle of heat treatment is that by a
- the solution annealing is carried out for conventional piston alloys at temperatures between 480 ° and 550 ° C, wherein this temperature is chosen so that a sufficient amount of alloying elements is dissolved in the solid solution, so that the hardening effect after quenching and outsourcing actually occurs.
- the determining parameters here are in particular the solution annealing temperature, the preheating time, the temperature of the coolant, the temperature of the piston shaft at the moment of quenching and the aging temperature and duration.
- the piston or the piston shaft is forged from an iron alloy and then suitably cooled or heat treated to achieve the required strength and the desired residual stress state.
- the subsequent processing can be made from the forged a complete, one-piece piston or a piston base, which results in combination with a piston upper part by joining (eg by welding, gluing, soldering, etc.) or screw a piston.
- Fig. 1 shows an inventive two-stage forging process for
- Fig. 2 is an illustration of the two-stage according to the invention
- 3 is a view as in Fig. 1, but with a divisible
- Fig. 4 is a representation as in Fig. 2, but with spread two-piece second forging punch during the second forging stage.
- FIGS. 3 and 4 each show a complete sectional view parallel to the pin axis 4.
- FIGS. 1 and 3 a first forging stage of the overall two-stage forging method according to the invention is shown, whereas in FIGS. 2 and 4, the respectively associated second forging stage is shown.
- the skirt walls 2 are at least slightly conical outward and the box walls 3 have a hub inner side 7 approximately parallel to the piston axis 6 and one for the free End, that is in the present case down and inward pointing
- the shaft walls 2 are in the
- FIGS. 3 and 4 Sectional views according to FIGS. 3 and 4 not visible, since they are above or below the image plane.
- the box walls 3 are now formed with a second forging punch 9 in such a way that whose hub outer sides 8 are directed substantially parallel to the piston axis 6 or slightly outwards (cf., broken line in FIG. 2) and their inner sides 7 towards the free end, that is to say in the present case, downward.
- the shank walls 2 are simultaneously pulled into a position approximately parallel to the piston axis 6 and thereby define the outside diameter of the piston shank 1.
- Piston lower part are forged with the forging method according to the invention or even a complete piston.
- the skirt walls 2 are drawn inwards by the widening of the box walls 3 until they rest against an outer circumferential surface 10 of the second forging die 9 that is parallel to the piston axis 6.
- this outer lateral surface 10 does not run conically, but in the sectional view according to FIG. 2 approximately parallel to the piston axis 6.
- the first and second forging dies 5, 9 are pressed at the respective forging stage against a die 1 1, wherein the located between the forging punch 5.9 and the die 1 1 piston shaft 1 either during the entire forging process in the die 1 1, that is remains in a die housing the forging apparatus 12 or between forging with the first forging punch 5 and the
- the piston skirt 1 can be made of, for example, an aluminum alloy, a magnesium alloy, a ceramic or an iron-based material
- the second forging punch 9 is designed as a split forging punch.
- the first forging stage is performed in accordance with FIG. 3 analogously to the first forging stage of FIG. 1, wherein the hub inner sides 7 are formed parallel to the piston axis 6 and the hub outer sides 8 obliquely downwards and inwards.
- the hub inner sides 7 are formed parallel to the piston axis 6 and the hub outer sides 8 obliquely downwards and inwards.
- the adjoining second forging becomes the first
- the forging device 12 can be produced comparatively easily and economically, in particular pistons or piston shanks 1 with oblique box walls 3, with the oblique box walls 3 a
