Definitions

  • the invention relates to a tool for compacting the surface of a powder metallurgy produced component, with a die and a punch, wherein in the die a recess is arranged, which extends from a first die opening to a second die opening, and a wall surface for conditioning of Component, and the punch has a punch length and a punch surface, wherein an inner diameter of the recess of the die from the first die opening to the second die opening becomes smaller or an outer diameter of the punch is larger over the punch length, and wherein on the wall surface of the die or on a stamping surface is arranged a compression element, a method for compacting the surface of a powder metallurgy produced component, with a tool having a die and a punch, wherein the component through the die or the punch through a recess of the component is moved while it is compacted surface, and a powder metallurgical, manufactured component with a component body having at least one compacted side surface or at least one recess with at least one compacted
  • Sintered parts ie workpieces made of pressed and sintered metal powder, have long been an alternative to cast or from the fully machined workpieces.
  • porosity of the sintered parts has a negative effect on the flexural strength and the wear resistance, which limits, for example, the use of powder-metallurgically produced gears in high-load gearboxes.
  • a method using a die tool for this purpose is known from US 6,168,754 B1 known.
  • a sintered blank that is a pressed powder metal and then sintered part is compacted on its outer surface by this is pressed by a multi-stage die tool.
  • the die tool comprises a plurality of die plates spaced apart from each other and axially spaced with die openings substantially correspond to the shape of the sintered blank, but the inner diameter decreases gradually and is smaller than the outer diameter of the sintered blank.
  • the outer periphery of the sintered part is plastically and elastically deformed, whereby the surface is compacted and the sintered part receives its final dimension.
  • the distances between the die plates allow the sintered part to expand by expanding a portion of the elastic deformations after each die plate.
  • the sintered part undergoes intermediate relief after each die plate, as a result of which a compressive residual stress remaining after deformation in the sintered part is built up in stages.
  • a method of surface compacting a sintered body in which a sintered part is moved in a die tool along an axis in a pressing direction through a plurality of die sections from a first die section at a first die opening into a last die section, wherein a wall surface of each die section forms at least one pressing surface the one contact surface formed by an outer surface of the sintered part is pressed, and one, lying in a cross section with respect to the axis, defined by the pressing surface inner contour corresponds at least approximately to an outer contour defined by the contact surface.
  • the present invention is based on the object to provide an improved way to compact the surface of a powder metallurgy produced component.
  • the advantage here is that relatively small compression stages are achieved by the thread-like formation of the compression element, whereby a material-friendly deformation is achieved, which is further supported by the impact of the component on the oblique Umformkante the compression element.
  • the tool itself is still relatively simple.
  • the die can consist of a single part, as well as the stamp.
  • the components compacted by the process or tool also exhibit a reduction in noise in the application of the components, presumably due to the particular surface topography created during and through compaction.
  • Another advantage is based on the fact that in the free spaces between the compression areas, ie in the relaxation zones, used forming oil can deposit, whereby the cracking of the lubricating film during the deformation can be better prevented. It can thus reduce the stress on the tool and the oil consumption. As a result, the movement also has a longer service life.
  • a plurality of spiral-shaped compression elements are arranged distributed over the respective surfaces. It is thus not only a better or higher compression of the component achieved, but can thus be achieved in particular that a multi-point support is provided for the component in the tool so that tilting of the component during compression can be better avoided.
  • the plurality of compression elements are each offset by an equal angle value to each other, whereby these effects are enhanced.
  • the one or more thread-like compression element (s) has or have a thread pitch that varies over the length of the or the compression element (s). It is thus achieved that areas are created over the length of the compression section of the tool, which have a different compression effect on the component surface, ie areas with greater compression effect and areas that have a greater relaxation effect on the component can be formed.
  • the one or more compression element (s) may have a chamfer or a rounding, in order to at least largely avoid a higher wear on the tool, or on the other hand to allow a "smoother" transition of the component from the compression areas in the relaxation areas and vice versa, without that by a sheep edged step unintentional material removal takes place on the component or that the edges erupt at the transitions of the tool.
  • the inner diameter of the recess in the die can decrease linearly or the outside diameter of the punch increases linearly in the pressing direction. It is thus simplifies the production of the tool. In addition, possibly fluctuating raw diameter of sintered components due to production can be better compensated.
  • sintered components depending on the composition, also allow different degrees of deformation in one compacting step, or it is better for the successive compacting steps in the tool to be different Forming degrees is performed - to allow the inner diameter of the recess in the die progressively or degressively decrease or increase the outer diameter of the punch in the pressing direction progressive or degressive.
  • the end portion of the recess in the die or the punch may be cylindrical, which end portion may also be free of compression elements in order to achieve the straightening of the component.
  • the Fig. 1 and 2 show a longitudinal section through and a plan view of a die 1 for a tool for surface compaction of a component 2 by moving it along an axis 3 through the die 1.
  • This comprises a MatrizengrundMech 4, which has a recess 5 extending from a first die opening. 6 extends on a first die surface 7 to a, the first die opening along the axis 3 opposite the second die opening 8 at a second die surface 9 continuously through the die body 4 and whose cross section is adapted to the cross section of the component to be compressed 2.
  • the recess 5 has a wall surface 10 for abutment of a component surface 11 of the component 2.
  • the recess has an inner diameter 12 which, beginning at the first die opening 6, becomes smaller in the direction of the second die opening 8, as a result of which the recess 5 tapers along at least part of a pressing length 13 of the die 1 along the axis 3.
  • the component 2 consists of pressed and then sintered metal powder, so it is made by powder metallurgy, the methods and materials for producing such a sintered blank from the prior art are well known and therefore not explained in detail.
  • the component 2 is designed disc-shaped in the illustrated embodiment and has on the component surface 11 has a diameter 14, which corresponds to the surface densification of a raw diameter 15 and after the surface compression to a smaller end diameter 16.
  • the compression element 17 On the wall surface 10 and projecting over this at least one compression element 17 is arranged.
  • the compression element 17 has a thread-like shape, thus extending from the region of the first die opening 6 to the region of the second die opening 8 in the form of a helical or spiral, therefore, can also be referred to as Umformspirale. It is thus generated with the compression element 17, an oblique Umformkante to compaction. Due to the slope of the compression element 17, so the forming spiral results in a "wandering Umformddling" or "a wandering Umformkante" along the component circumference.
  • the compression element 17 need not necessarily be arranged beginning at the first die opening 6, but that an inlet region in the die 1 at the may be formed first die opening in which no compression element 17 is arranged to facilitate the insertion of the component 2 into the die.
  • an end portion 18 of the recess 5 of the die 1 may also be free of the compression element 17 or compression elements 17.
  • this end portion may have an inner cross section that corresponds to the outer contour of the finished compacted component 2, that is, for example, have a cylindrical cross-section, so as to allow the same in a final step of the compression of the surface of the component 2.
  • the compression element 17 extends on the wall surface 10 starting from the first die surface 7 to the second die surface 9.
  • the compression element 17 preferably extends continuously without interruption in the recess 5, but it is possible that this compression element 17 is divided into individual, slightly spaced compression member sections.
  • Fig. 2 can be seen in dotted and dash-dotted lines, there is the possibility that several compression element 12 are arranged on the wall surface 10, so for example two, preferably three (as shown), or four, five, six, etc.
  • the compression elements 17 are preferably in the form of a multi-start thread, so for example three-thread, arranged, the resulting "Verdichtungs sautes" are each offset by a respective same angular value to each other, resulting from the division of 360 ° by the number of thread-like compression elements 17 , ie for example by 120 ° in the arrangement of three compression elements 17th
  • the or the compression element (s) 17 are worked out of the wall surface 10 of the recess 5, that is integrally formed with the die 1.
  • the surface compression of the component 2 is carried out by being introduced through the first die opening 6 in the recess 5 and subsequently moved to and through the second die opening 8, wherein the component surface 11 of the component 2 against the or the compression element (s) 17 of Die 1 is pressed.
  • the direction of movement of the component 2 can also be reversed so that therefore the component 2 is not removed from the die 1 via the second die opening 8 but the first die opening 6.
  • the inner diameter 12 which is defined by the clear width between opposite or cooperating portions of the wall surface 10 of the recess 5, wherein the or the compression element (s) 17 is seen as part of the wall surface 10 and
  • the term inner diameter 12 is not to be understood as limited to circular cross sections, but also as a clear width between interacting press surface parts, which need not necessarily go through the axis 3 of the die 1.
  • the diameter 14 on the component 2 is not limited to radial directions.
  • the recess 5 preferably has an inner diameter 14 which is at least not smaller than the raw diameter 15 of the component in order to simplify the insertion of the component 2.
  • the movement of the sintered part 2 in the die tool 1 preferably takes place in a straight line along the axis 3 in a pressing direction 19 from the first die opening 6 to the second die opening 8, followed by the removal of the component 2 from the die 1, via the second die opening 8 or after Direction of movement reversal against the pressing direction 19 through the first die opening 6, for which purpose an ejector element can be arranged in the second die opening.
  • the rectilinear movement in the direction of the axis 3 can also be superimposed by a rotational movement, whereby the component 2 in the die 1 performs a screwing movement.
  • the component surface 11 also includes screw surfaces.
  • the movement of the component 2 takes place in this case about a screw axis which coincides with the axis 3 or parallel to this, for example, when the screw surface to be compacted on the component surface 11 is not disposed on the entire circumference of the component 2 and this has no rotationally symmetrical body ,
  • the pitch of the screwing movement which must be different from the pitch of the thread-like compression element 17 in order to achieve a surface compression, ie to prevent the component 2 from sliding in the compression passage of the compacting element 17 ,
  • the direction of movement of the component 2 in the die 1 can, as well as the speed of movement to optimize the surface compression have any course and, for example, include a reversal of movement, motion arrest, very slow but also very fast movements. It is possible that the compression is carried out with at least two relative reversals of movement of the component 2 to the die 1, so the component 2 is moved, for example, down through the die 1, in the die 1, the component again a short distance against the original direction of movement is moved back and then moved within the die 1 after a new reversal of motion back in the original direction through the die 1. Of course, this process can be repeated several times or the die 1 can be moved instead of and / or in addition to the component 2.
  • the component 2 after partial compression also allows partial relaxation, wherein the material of the component 2 springs back. It is thus a component and tool gentle compression possible, since smaller forming forces are required by the occurring repeated compression and relaxation.

  • the required relative to the process implementation relative movement between the component 2 and the die 1 can be done by movement of the component 2 and / or by movement of the die 1, wherein the component 2 and the die 1 are each connected to a suitable drive or a fixed frame can or the component 2 with the help a punch or an upper punch and a lower punch is moved through the die 1, as is known per se.
  • the compression element 17 is not designed to extend over the entire inner circumference of the recess 5, but that a predeterminable portion of the wall surface 10 of the recess 5 in the direction of the axis 3 is free of compression elements 17. It is thus possible to produce components 2, after the movement of the component 2 during compression preferably takes place in the direction of the axis, which are surface-compacted only in a partial region.
  • components 2 which have a different degree of surface compaction in different areas by the compression element 17 is formed over a portion of the press length 13 of the die 1 extending continuously over the circumference of the recess 5 or only in a partial region of the circumference of the recess 5 over the press length 13 at least one further thread-like compression element 17 is arranged.
