Definitions
- the present invention relates to the use of a wear-resistant steel component.
- wear-resistant steels are available on the market in the prior art.
- the wear-resistant steels are used in machines wherever high abrasive wear is to be expected.
- This high abrasive wear finds its origin mainly in the types of wear shock load and fretting.
- surface segments are continuously removed from the steels, so that it comes to such a wear that these machine components must be replaced as soon as they have fallen below a critical level of wear.
- Object of the present invention is therefore to show a way to extend machines and components of machines that are exposed to high abrasive wear in their life and to operate more cost-effectively.
- a hot-formed and press-hardened, wear-resistant steel component having a hardness of between 500 and 700 hardness Brinell (HB), as a steel component in construction machines is particularly preferably used as an excavator bucket, concrete mixer bucket, auger bucket or transport bucket for conveyors. Supplementary use in construction machines, which are exposed to high abrasive wear, are also part of the use of the invention.
- the use according to the invention further provides for the use of a hot-formed and press-hardened, wear-resistant steel component having a hardness of between 500 and 700 HB as a steel component in agricultural machines. Particularly preferred here is a wear-resistant steel component, the use of a plow or a cutting device of harvesters.
- the wear-resistant steel component as Schar, Scharspitze or Scharmesser, Scharblatt, baffle, Scharfuß, holder for share point, chisel, rake crusher, plow or plant, plant wedge, system saver, sole block or Sole log, Sech, mouldboard or Mollblech or coating rail, mouldboard edge or Mollblechkante, insert plate, strip or strip body or scraper or comes to a cutting device of a harvester as a knife or blade used.
- the steel component is used in mining machines, preferably in conveying elements, crushing elements or sorting systems.
- the wear-resistant steel component becomes utility, transportation, clearing or maintenance machinery, preferably in snow removal machines or as a coulter and / or scraper bar in a snowplough or in a snowthrower.
- the wear resistant steel component is used in home, garden, do-it-yourself or craft machinery exposed to high abrasive wear.
- the wear-resistant steel component may be formed in particular as a sliding plate or used as such.
- the wear-resistant steel component can furthermore be designed in particular as an ear lifter or used as such.
- the wear-resistant steel component Even has a hardness greater than or equal to 700 HB.
- the excavator bucket according to the invention in its entirety consists of wear-resistant steel, without weaknesses are produced by joining seams or the like or weak points are compensated by the aftertreatment such that excavator buckets used in the invention have a high durability and resistance to abrasive wear.
- a significant advantage of the use according to the invention is that the manufacturing costs and also the operating costs of the hot-formed and press-hardened, wear-resistant steel components decrease dramatically, since replacement intervals are increased and longevity is increased. With the use according to the invention it is possible to use components with complex component geometries.
- the use according to the invention is further distinguished by the fact that the steel components are at least partially aftertreated, for example by a partial heat treatment.
- the heat treatment By the heat treatment, the possibility is given to post-process the wear-resistant steel component used in accordance with the invention in further steps, without significant limitations of the wear-resistant hardness occurring.
- the heat treatment can be carried out in several stages or steps. A particularly preferred heat treatment is carried out, for example, by heating the steel component to a heating temperature in a range between 500 and 900 degrees, holding the heating temperature for a holding time and then cooling it from the heating temperature in at least one phase.
- An advantage of the aftertreatment according to the invention is that it is possible to produce material properties in a targeted manner in the desired ranges in a process-reliable manner which is suitable for the wear-resistant use of the invention Steel component needed.
- the starting temperature of the warm-up is always lower than the martensite start temperature, preferably the starting temperature is below 200 degrees Celsius.
- a steel alloy is used for their production which has the following alloying elements in each case in percent by weight:
- Ni nickel
- Ni nickel
- the alloying components used in accordance with the invention make the steel alloy particularly suitable for its soft formability and cooling behavior for optionally cold preforming and thermoforming combined with tool hardening while achieving the desired hardnesses for a wear resistant composite material composition.
- the steel component used according to the invention is produced with bending angles of more than 5 degrees.
- steel components used in the invention it is possible to use highly complex geometries such that bending angles of more than 5 degrees, in particular more than 10 or even 15 degrees are present. For example, it is therefore possible to reshape geometries in the form of an excavator bucket or the like into a final state with only one method step, and subsequently to use the manufactured components according to the invention.
- the wear-resistant steel component has a hardness of more than 550 HB.
- the unhardened steel sheet is shaped by the hot forming process and then press-hardened.
- wear-resistant steel components which have a hardness of up to 450 HB, these being designed substantially as a steel plate or planar steel components.
- At least one through opening and / or at least one recess is introduced into the steel component in a punching step by means of at least one punching tool. It is preferred according to a first variant, if the at least one continuous opening and / or the at least one recess during a period of hot forming and / or press hardening is introduced into the still warm or at least not yet completely cooled Stahlbauteit. In the case of this first variant, it is particularly preferred if the at least one hole tool after the punching step is led out of the still warm or at least not yet completely cooled steel component again. According to a second variant, it is preferred if the at least one continuous opening and / or the at least one recess is introduced before hot forming.
- a through aperture and / or at least one recess is or are introduced into the wear-resistant steel component by means of a previously mentioned punching step, it is particularly advantageous if the at least one through opening introduced into the steel component has a chamfer or a face toward the steel component is provided to both surface sides of the steel component out with a chamfer and / or the at least one recess is provided with a chamfer. In this case, it is highly preferred if the chamfering of the at least one continuous opening and / or the at least one recess is carried out during a period of hot working and / or press hardening in the warm or at least not yet fully cooled steel component.
- Fig. 1 is a perspective view of a blade tip of a plow, which is provided with a hole, the hole towards the concave curved surface side, having a chamfer
- the hot-formed and press-hardened, wear-resistant steel component is attached to a Used plow as a share tip 1.
- the share tip 1 has a concave curved surface side 2.
- the punching step is carried out immediately after hot working and before the start of press hardening. This ensures that the hole 3 is introduced into the still warm steel component.
- the hole tool is thereby led out again directly after the punching step from the still warm steel component, thereby avoiding that a shrinkage of the steel component takes place or could take place on the hole tool.
- the steel component is provided with a chamfer 4.
- the chamfering of the hole 3 is carried out after the perforation step has been carried out in the still warm steel component.
