Definitions
- the present invention is based on a method for producing a sheet metal product, the sheet metal product being made from a sheet metal pre-product by mechanical forming.
- Sheet metal pre-products are usually processed further using mechanical forming processes, such as deep drawing.
- the forces introduced into the sheet metal material are transmitted to the sheet metal pre-product via the sheet metal surface.
- the geometry of the sheet metal product and the frictional forces between the sheet metal surface and the forming tool that occur in the forming process result in some very high local stresses on the sheet metal surface. These local stresses, which are made up of normal and shear forces, can be subject to considerable changes during the forming process. For an optimal forming result, it is necessary to be able to control the sheet metal flow during the forming process.
- the sheet metal flow is controlled, in particular, by influencing the retaining forces, which counteract the drawing force of the forming process. This influence occurs, for example, through additional lubrication with lubricants. This leads to a local reduction in frictional forces and thus to a reduction in the restraint forces.
- An increase in the restraint forces can be achieved, for example, by using pull beads.
- Laser texturing processes are known from the publication DE 10 2012 017 703 A1, with which chem skin-pass rollers can be verse with a deterministic, ie geometrically determined texture.
- This texture is applied to the surface of the skin during the skin pass process
- Transferred sheet metal pre-products to be processed as a negative, ie elevations on the surface of the Walzeno result in valleys in the surface of the sheet metal pre-product and vice versa.
- the depressions made in this way in the surface of the sheet metal pre-product are used as so-called lubricant pockets, which hold a lubricant applied to the sheet metal surface and can carry it with them during the forming process.
- the functionality of the lubricants used is essentially determined by the additives added to the lubricant.
- the additives can, for example, cause the formation of a boundary layer through an accumulation of polymer chains or also through chemical reactions on the metallic surfaces of the forming tool and sheet metal precursor and prevent direct contact between the surfaces of the forming tool and sheet metal precursor.
- the bond between the polymer chains is based on van der Waals forces. Therefore, these can be shifted relative to one another with relative ease.
- the bonding of the polymer chains to the surfaces of the forming tool and sheet metal intermediate is based on a dipole bond.
- the boundary layer is usually a few nanometers thin and can easily be detached from the surfaces of the forming tool and sheet metal pre-product.
- the invention is therefore based on the technical problem of providing a manufacturing method for sheet metal products which does not have the disadvantages of the prior art, but instead offers effective lubrication when the sheet metal pre-product is formed while using less lubricant.
- This object is achieved by a method for producing a sheet metal product from a sheet metal pre-product, wherein at least one surface of the sheet metal pre-product is coated with a Beschich device, wherein the sheet metal pre-product is rolled, with depressions being rolled into the surface during the rolling, after the coating and Rolling lubricant is introduced into the depressions, whereby the sheet metal pre-product is mechanically reshaped with a shaping tool after the introduction of lubricant, thereby marked net that the surface is coated in such a way that the coating in the forming tool during the forming process, in particular with relative movement between the sheet metal and tool surface, is elastically deformable under loads of 0.5 MPa to 20 MPa and plastically deformable under loads above 20 MPa .
- the method according to the invention enables the lubricant in the depressions to be transported in a targeted manner to the critical areas of the forming tool as lubricant pockets.
- the depressions enable the surface of the sheet metal pre-product to absorb the lubricant and to transport it largely without loss. Only at high loads, i.e. where the lubricant is required for lubrication between the sheet metal pre-product and the forming tool, is it released locally through plastic deformation of the depressions.
- the volumes of the depressions correspond to the required amount of lubricant. It is conceivable that the amount of lubricant required is between 0.5 g / mm 2 and 1 g / mm 2 . It is also conceivable that sheet metal blanks or sheet metal in strip form are provided as the sheet metal intermediate product. It is also conceivable that a skin pass roller is used as the roller for rolling the indentations into the sheet metal pre-product, to which a geometric texture has been applied, in particular using a laser texturing process. All sheet metal deformations are conceivable as mechanical reshaping of the sheet metal pre-product to the sheet metal product. Examples are bending, deep drawing, twisting, pressing and stretch drawing. The coating is preferably between 1 pm and 30 pm, in particular between 2 pm and 15 pm, thick.
- the surface is coated in such a way that the coating in the forming tool during the forming process, in particular with relative movement between the sheet metal and tool surface, under loads of 0.5 MPa to 15 MPa elastically deformable and under Loads above 25 MPa is plastically deformable.
- the existing loads in the forming tool are expressed as pressure, i.e. force per area, on the surface of the sheet metal pre-product.
- pressure i.e. force per area
- the depressions are rolled in as closed depressions in relation to a main plane of extent of the sheet metal pre-product. This advantageously enables safe and largely loss-free transport of the lubricant. Due to the closed shape in relation to the main plane of extension of the sheet metal pre-product, no lubricant can run out of the recess from the side. This also ensures that the lubricant is released in the event of a plastic deformation of the recess and is not pressed away from the area of the plastic deformation along a non-closed recess.
- the depressions are rolled in I-shaped, rectangular or square in relation to the main plane of extent of the sheet metal pre-product. This results in well-shaped depressions, for example. It has been shown that this enables very effective lubricant transport. However, it is also conceivable that the depressions are round, oval, triangular or cross-shaped in relation to the main plane of extent of the sheet metal pre-product.
- the depressions are rolled in with a depth of 2 pm to 15 pm, preferably 2 pm to 10 pm and particularly preferably from 2 pm to 5 pm. This enables the volume of the depressions to be well adapted to the required volume of lubricant.
- the depth of the Fung in the context of the present invention is the depth of the depression after the surface has been coated.
- the depressions are rolled in with a ratio of depth to volume of the depression of 1: 3 to 1:15 and preferably 1: 5 to 1:10. A corresponding ratio also has a positive effect on lubricant transport and targeted local wetting with lubricant.
- the volume of the depression in the context of the present invention is the volume of the depression after the surface has been coated.
- depressions are rolled into at least 30% of the surface of the surface of the sheet metal pre-product. This ensures that lubricant is actually transported to wherever high loads in the forming tool make it necessary to introduce lubricant.
- the depressions are rolled in such that a bottom of the depression has a smaller area than the projection of the depression onto the main plane of extent of the surface.
- the depressions are rolled into, for example, trough-shaped or cup-shaped. This is particularly advantageous when releasing the lubricant when the recess is deformed.
- the depressions are rolled in such that the walls of the depressions enclose an angle of 105 ° to 140 ° and preferably 110 ° to 120 ° with the main plane of extent of the surface.
- the angle between the walls of the depressions and the main plane of extent of the surface the volume changes of the depressions can be specifically adjusted by the load.
- Correspondingly designed angles between the walls of the wells and the main plane of extent of the upper surface have proven to be advantageous.
- Zinc is ideal as a cathodic corrosion protection coating. If the zinc is processed accordingly, the flow limit ze of the zinc exceeded at the highly stressed points in the forming tool, whereby the lubricant is advantageously released in a targeted manner.
- the sheet metal pre-product is coated by hot-dip galvanizing, the sheet metal pre-product being coated before rolling (rolling in the depressions).
- Hot-dip galvanizing is well mastered and has already been integrated to a large extent in manufacturing processes.
- the surface is preferably coated with a closed coating, the coating not being pierced when the depressions are rolled in.
- the sheet metal pre-product is coated electrolytically, the sheet metal pre-product being coated after the rolling (rolling in of depressions).
- the coatings follow the uncoated course of the surface to be coated very precisely. The coating can therefore take place after the depressions have been rolled in. This sequence enables a very uniform coating, even within the depressions.
- Another object of the present invention for solving the above-mentioned task is a sheet metal product produced using the method according to the invention.
- Figure 1 shows schematically the method according to an exemplary embodiment of the present invention.
- Figure 2 shows schematically a section of a sheet metal pre-product according to an exemplary embodiment of the present invention.
- Figure 3 shows schematically a section of the surface of a Blechvorpro products according to an exemplary embodiment of the present invention.
- the sheet metal pre-product 2 is provided as a strip (coil material) or Pla tine and rolled with skin-pass rollers 3.
- the skin pass rollers roll 3 trough-shaped depressions (see Figure 2) into the surface of the sheet metal pre-product 2.
- the depressions are several micrometers deep, several micrometers long and wide, regularly arranged and are rolled into about 40% of the surface.
- the skin pass rollers 3 have previously been processed, preferably with a laser texturing process, in such a way that they have a corresponding negative for rolling in the depressions on their surface. It should be noted that the negative has an elevation for each depression, the elevation being higher than the depression rolled in by the elevation being deep.
- a skin pass liquid for example, is preferably introduced between the sheet metal intermediate 2 and skin pass roll 3.
- the surfaces in the coating installation 4 are electrolytically coated with zinc approximately 7 ⁇ m thick.
- the zinc layer follows the surface geometry of the underlying surface, in particular the rolled-in depressions.
- the coating with zinc is carried out by means of hot-dip galvanizing. In this case, however, the coating would have to be carried out before the rolling / skin-passing, since a coating applied by hot-dip galvanizing affects the surface geometry of the underlying surface, in particular the rolled-in surface Wells that follow less well compared to electrolytic plating. The rolling in of the recesses after the hot-dip galvanizing would, however, compensate for this disadvantage.
- the lubricant 8.1 is now introduced into the depressions on the coated surface.
- the rolled and coated sheet metal pre-product 2 is cut to length from the strip to form a blank and then subjected to forming in a forming tool 5.
- a forming tool 5 One example is deep drawing as a possible form of forming.
- the still platinenför shaped sheet metal precursor 2 is inserted into the forming tool 5.
- Outer edges of the sheet metal pre-product 2 are held by hold-down devices 5.3 of the forming tool 5 on supports 5.4 of the forming tool 5, while the punch 5.1 presses the inner area of the sheet metal pre-product 2 into the die 5.2.
- FIG 2 a section of a sheet metal pre-product 2 according to an exemplary embodiment of the present invention is shown schematically.
- a section orthogonal to the plane of extension of the surface 7 of the sheet metal intermediate product 2 can be seen.
- the regularly arranged depressions 6 are several micrometers deep and have the bottom 6.1 and the walls 6.2.
- the walls 6.2 enclose an angle ⁇ with the main extension plane of the surface 7 of 110 ° to 120 °.
- FIG. 3 schematically shows a section of the surface 7 of a sheet metal intermediate product 2 according to an exemplary embodiment of the present invention.
- Recesses 6 can be seen, the projections of which onto the main plane of extent of the surface 7 are I-shaped.
- the surface 7 has the depressions 6 on more than 30% of its area.
