Definitions
- the invention relates to a method for producing at least one component for a furniture fitting, in particular a rail, particularly preferably for a drawer pull-out guide. Furthermore, the invention relates to a drawer pull-out guide for movably mounting a drawer on a furniture body according to the preamble of claim 12.
- a high use of material leads to a high weight and increased costs in serial production. It is therefore desirable to use as little metal as possible, especially since resource-conserving use of raw materials has both ecological and economic advantages.
- a method for producing pipes and extruded profiles is already known from document DE 102007018927 A1, with chamfers being used in the pipes or extruded profiles in order to minimize the risk of injury and a degree of deformation after a cutting process step, without generating cutting scrap.
- the disadvantage of the prior art is that only semi-finished products are used as such for further transport of the semi-finished products, but then the tubes and extruded profiles have to be adapted for the respective area of application and the structural design of the semi-finished products is determined by the primary forming process.
- the procedure for a specific area of responsibility with defined tasks, individual purposes, constructive designs and specific challenges does not exist.
- the objective technical task of the present invention is therefore to specify a method for producing at least one component for a furniture fitting that is improved compared to the prior art and an improved drawer pull-out guide, in which the disadvantages of the prior art are at least partially eliminated, and which in particular characterized by a reduction in metal waste during the manufacture of component parts for a furniture fitting.
- a flat, preferably metallic, particularly preferably steel, sheet metal with a longitudinal extension, two cover surfaces and two side surfaces spaced apart by a width of the sheet metal is used as a semi-finished product of the at least one component, preferably rail, provided, wherein the sheet metal has a wall thickness in the range of 0.5 mm and 1.5 mm, the sheet metal is provided with at least one notch on at least one top surface, preferably by at least one embossing die and/or at least one embossing roller, wherein the at least one indentation is arranged transversely, preferably essentially orthogonally, to the longitudinal extension, the metal sheet is bent so that a profile of the at least one component, preferably a rail, is formed in a cross section orthogonal to the longitudinal extension, the bent metal sheet is mechanically separated in the area of the at least one notch, preferably broken off, particularly preferably kinked and divided.
- Particularly light components with a small wall thickness can be manufactured particularly cheaply with little effort and low plastic deformation by the process, where also an aesthetically pleasing appearance of the assembly component is given to a large extent.
- the sheet metal (present as flat steel, for example) is profiled via indentations before a bending process, complex geometries are also involved in the bending process to form the at least one
- At least one notch follows the complex geometry of the profile of the at least one component component in order to be able to produce component components in series particularly efficiently.
- the profile of the at least one assembly component is not undesirably impaired by the at least one notch, in particular due to the introduction before the bending process.
- mechanical cutting is understood to mean all cutting processes that do not generate any material waste, for example due to cutting cutting processes.
- the assembly component can, for example, a rail like a
- a body rail or a drawer rail in particular for a drawer pull-out guide as a furniture fitting, or a hinge arm, an adjusting arm, a hinge part, a housing part or the like for a flap fitting or some other furniture fitting such as a hinge.

- the longitudinal extension of the at least one component can be flexibly adjusted via the positioning of the at least one indentation, with the metal sheet not having to be present with the appropriate length dimensions in advance.
- the at least one component can be a furniture rail, a cabinet rail, a center rail, a drawer rail, etc., for example.
- the at least one indentation can act as a predetermined breaking point by strain hardening in the mechanical breaking process without cutting, chipping and preferably without flash, whereby particularly favorable material characteristics of the component are achieved in an area around the at least one indentation.
- the process of breaking off the assembly component can be carried out using cutting tools without cutting cuts, such as a ram or the like, or manually.
- a semi-automatic or automatic hydraulic or pneumatic drive is particularly preferably used to remove the at least one component from a remaining material by pressure and/or tension (e.g. by pulling apart), with no punching tool, saw or grinding wheel (with conditional burr and post-processing steps) is required.
- the at least one notch can act as a defined break-off edge to form the at least one structural component, with the tensile/compressive loads being focused on the at least one notch.
- the at least one notch can be introduced into the sheet metal in strip form, for example using an embossing stamp such as a notching stamp or an embossing roller such as a notching roller, with generally a tapering in the form of at least one chamfer on an end surface of the profile of the component after the mechanical separation (breaking off). is arranged.

- the indentations 13 are made using an embossing stamp 11 and an embossing roller 12, in which case generally only one embossing roller 12 or embossing stamp 11 or (preferably) two embossing rollers 12 or embossing stamps 11 can be provided in order to cut the indentations 13 into the metal sheet 5 to be introduced before a bending and/or folding process.
- FIG. 4a shows the rail 1, which is provided as a drawer rail 3, in a perspective view before a process step of separating the rest of the profile material.
- a rail 1 designed as a body rail 2 can be provided in an analogous manner.
- Fig. 5 shows the rail 1 after breaking off via the notches 13
- the taper 16 has a taper cross-section 18 parallel to the longitudinal extension 6 of the sheet metal 5 in the form of a isosceles triangle 19 has.
- a bead-shaped end section can remain on the taper 16 or the taper cross-section 18 can be convex or concave.
- no chip-removing process step with material waste is required for the cutting process.
- Fig. 6 shows the rail 1 during the breaking off via two notches 13, the bent metal sheet 5 being broken in the area of the notches 13 without cutting, without punching and without waste, with the notches 13 being used as a predetermined breaking point during a buckling of the bent sheet metal 5.
- the splint 1 is formed without post-processing; However, depending on the requirements made of the rail 1, it can still be subjected to post-processing steps.
- Fig. 7 shows the rail 1 after breaking off via the notches 13, the tapering 16 of the rail 16 having an angle 31 (cf. Fig. 3c) of 90° in the viewing direction orthogonal to the longitudinal extension 6, the end faces 17 being designed without burrs are. If only one notch 13 is used for the breaking off process, an angle 31 of 45° can also be used, for example, in which case the taper 16 can be designed as a right-angled triangle 19 in contrast to an isosceles triangle 19 .
