Description

Process for producing at least one component for a furniture fitting

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 general problem in the production of structural components such as rails, in particular for the furniture industry or furniture branch, is the need for metal, which is necessary for the production of one of the rails or the like. 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.

One measure for saving metal is the use of thin-walled sheet metal, the weight of the rail also being able to be reduced in an advantageous manner. In the prior art, rails, in particular for the furniture industry, are usually cut to length by means of a separating cut—for example using a saw blade of defined width—so that a rail with defined dimensions is generated. However, this produces a high level of metal as a waste product, and there has been a long-standing need in the furniture industry to achieve material savings by eliminating such scrap metal.

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. However, the procedure for a specific area of responsibility with defined tasks, individual purposes, constructive designs and specific challenges does not exist.

Further methods are known from the documents US 2009/019804 A1, DE 19641 144 A1,

DE 102007018 927 A1, US Pat. No. 2,222,842 A and DE 2030561 A1 are known.

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.

This object is solved by the features of claim 1.

It is therefore provided according to the invention that the following process steps are carried out in chronological order: 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.

This makes it possible for the first time that material waste, which occurs in the furniture industry in the case of conventional component parts such as rails or the like as a result of the machining process for separating the rail from a profile material, can be effectively prevented. In mass production, this involves reduced disposal and/or recycling of scrap metal, cleaner component components and a cleaner processing environment, less post-processing work and significant cost savings in production, since processing steps and stamping waste or cutting waste - caused, for example, by a cutting width of a cutting tool - with of each manufactured component are accumulated.

The mechanical separation such as breaking, buckling or splitting without the aid of cutting tools such as saw blades was previously unknown in the furniture industry and above all in the case of structural components such as rails, especially since there has been meticulous effort to date, the complex geometric configurations of rails or the like - in the first place Line due to large material thicknesses and high cross-sectional diameter of the profiles with simultaneous high demands on geometrical accuracy and precision of the profile - to be affected as little as possible by using the cutting separation process, whereby it is also ensured according to the invention that the geometry of the profile of the at least one component component is precise in the cross section and over is maintained throughout the longitudinal extent.

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.

If 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

Component component possible, wherein the 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.

The technical term 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.

In addition, there is the positive property that the at least one component due to the lack of burrs - due to a cutting separation process - a lower risk of injury for a user of a piece of furniture and / or a fitter in the

Installation of the cast component represents and no post-processing is required. In addition, severing tools, for example, have a limited service life due to signs of wear, with maintenance and/or repair work in the mass production of component parts being able to be significantly reduced. 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. In the event of a bending load, 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 at least one notch preferably comprises two flanks, one flank being assigned to the at least one component after the breaking off process.

As stated at the outset, protection is also sought for a drawer pull-out guide for movably mounting a drawer on a furniture body, comprising at least one body rail to be fastened to the furniture body and at least one drawer rail to be connected to the drawer, which is mounted displaceably in a longitudinal direction relative to the at least one cabinet rail, the at least one cabinet rail and/or the at least one drawer rail having a profile formed from at least one flat sheet metal in a cross section orthogonal to the longitudinal direction characterized in that the at least one body rail and/or the at least one drawer rail is produced as a component by such a method, so that at least one, in particular two, end surfaces of the profile of the at least one body rail and/or the at least one drawer rail are tapered is trained.

However, the use of the method is applicable to furniture hardware other than drawer slides.

The longitudinal direction is generally identical to the longitudinal extension of the metal sheet. The taper particularly preferably extends over the entire profile of the at least one structural component in the end face.

Advantageous embodiments of the invention are defined in the dependent claims.

According to an advantageous embodiment of the invention, it is provided that the at least one notch connects both side surfaces of the metal sheet and/or at least two opposite notches are arranged on the two cover surfaces of the sheet metal, preferably one above the other in a direction orthogonal to at least one of the two cover surfaces.

A particularly symmetrical end face of the assembly component can be generated by notches lying one on top of the other, with notches arranged opposite and/or next to one another generally being able to have different depths and/or notch geometries. Provision is advantageously made for the bent sheet metal to be mechanically separated, preferably broken off, particularly preferably bent and divided, at at least two, preferably at least two notches lying one above the other.

In general, however, it is also conceivable to use only one notch for the mechanical separation process.

It has proven to be favorable that the at least one component is formed with a substantially burr-free taper on at least one, preferably two, end faces of the profile, it being preferably provided that the taper has a taper cross-section parallel to the longitudinal extension of the metal sheet essentially in shape of a preferably isosceles triangle, wherein the narrowing cross section is particularly preferably convex and/or concave.

The tapering is generally brought about by a combination of strain hardening through the introduction of the at least one indentation and plastic deformation in the mechanical separation process step and generally extends over the entire end surface of the profile.

According to an advantageous embodiment of the invention, it is provided that the bent metal sheet is broken in the area of the at least one indentation without separating cuts, without punching and without waste, with the at least one indentation being used as a predetermined breaking point during buckling of the bent metal sheet, it being preferably provided that the at least one assembly component is formed without post-processing.

The type of mechanical cutting is generally arbitrary, with no chip waste occurring during the mechanical cutting and, if necessary, post-processing by cutting can be provided - but this is not absolutely necessary in order to be able to use the at least one component directly as a furniture rail, for example. It has proven to be advantageous that the sheet metal has a wall thickness in the range of 0.6 mm and 0.8 mm.

The wall thickness of less than 1.5 mm, which is used in conventional structural components such as rails, results in a particularly light structural component that can be mechanically separated in a particularly favorable manner using the method according to the invention and has low material consumption.

An advantageous variant of the present invention consists in that the metal sheet is folded into a fold in the area of at least one side surface, preferably during the bending of the metal sheet.

A wall thickness can be doubled locally by a fold in order to increase strength and/or stability properties in desired areas of the structural component without doubling the weight of the structural component itself.

It is particularly preferred that the at least one notch in the form of a groove or a profiling with an opening angle in the range between 40° and 140°, preferably between 75° and 105°, particularly preferably essentially 90°, is introduced into the metal sheet.

For example, identical or different depths and/or geometries can be used for the at least one notch in order to act as a defined predetermined breaking point for tearing off and/or breaking off.

In an exemplary embodiment of the invention, it is provided that the at least one notch has a notch cross section parallel to the longitudinal extent of the metal sheet in the form of a triangle, a trapezium, a segment of an ellipse and/or a segment of a circle.

The at least one notch is particularly preferably present after the bending process to form the profile of the sheet metal in such a way that between the both top surfaces between 0.05 mm and 0.2 mm, preferably between 0.08 mm and 0.12 mm remain. Particularly preferably, the at least one indentation has a trapezoidal shape, with the smallest side length of the trapezoid between the two cover surfaces being between 0.1 mm and 0.4 mm, preferably between 0.15 mm and 0.25 mm.

According to a preferred exemplary embodiment of the invention, it is provided that exactly four notches arranged in pairs on the two cover surfaces are made in the flat sheet for each component, with the component being formed by breaking off twice, preferably consecutively, via the four notches of the bent sheet.

As a result, both the mechanical separation process can be favored and material savings can be maximized.

It has proven to be advantageous for the metal sheet to be provided with a large number of indentations arranged in pairs on the two cover surfaces and for a large number of structural components to then be broken off mechanically.

As a result, a large number of assembly components can be produced in series in a time-efficient manner and preferably without interruption using one and the same semi-finished product.

Furthermore, it is preferably provided that the taper comprises an angle in the range between 60° and 140°, preferably between 75° and 105°, particularly preferably essentially 90°, it being preferably provided that at least one, preferably both, end surfaces in Are formed substantially free of burrs.

The geometry of the taper can be flexibly adjusted via the geometry of the at least one indentation.

In a further embodiment it can be provided that the at least one cabinet rail and/or the at least one drawer rail has at least one fastening section with a Has a fastening side which can be brought into contact with the furniture body or the at least one furniture part at least in sections during assembly on the furniture body or at least one furniture part, the at least one fastening section having at least one, preferably circular, opening for the passage of a fastening means, preferably a screw, wherein the at least one opening is surrounded by a bead on a second side spaced apart from the fastening side by a material thickness of the fastening section, preferably between 0.5 mm and 1.5 mm, particularly preferably between 0.6 mm and 0.8 mm , which protrudes transversely from the second side.

The bead reinforces the perimeter of the opening, allowing the force from the underside of a screw head to be distributed over a larger area. The sinking of the screw head into the thin-walled metal of the fastening section can be reduced by the bead. The risk of damage to the peripheral edge of the opening can therefore be reduced in this way and material can be saved.

According to an advantageous embodiment of the invention, it is provided that the at least one cabinet rail and/or the at least one drawer rail is folded into a fold in the region of at least one profile surface of the profile.

A ratio of the load capacity of the rail or another component to the weight of the rail/component can be increased by the fold.

Provision is particularly preferably made for the at least one taper to have a taper cross-section parallel to the longitudinal extent of the metal sheet essentially in the form of a preferably isosceles triangle, with the taper cross-section preferably being convex and/or concave. According to a preferred embodiment, it is provided that the profile has at least one embossing, preferably oriented orthogonally to the longitudinal extent of the metal sheet, for stiffening the profile, it being preferably provided that the at least one embossing extends over at least two essentially orthogonal profile surfaces and/or or at least two embossings are provided, which are arranged alternately in the direction of an inner area and in the direction of an outer area of the profile.

The at least one embossing promotes the stability and/or strength of the at least one assembly component with a particularly efficient use of material.

Fig. 1 shows a drawer pull-out guide 4 for movably mounting a drawer on a furniture body (furniture parts are not shown in the illustrations for reasons of clarity), comprising a body rail 2 to be fastened to the furniture body and a drawer rail 3 to be connected to the drawer, which is positioned relative to the Carcass rail 2 is slidably mounted in a longitudinal direction 30 . The body rail 2 and the drawer rail 3 each represent a rail as a structural component 1 for a furniture fitting, which in this embodiment is in the form of a drawer pull-out guide 4 .

A carriage for guiding the drawer rail 3 relative to the cabinet rail 2 is arranged between the cabinet rail 2 and the drawer rail 3 . In general, a middle rail can be provided in addition, which is arranged on the cabinet rail 2 and/or the drawer rail 3 .

The body rail 2 and the drawer rail 3 have a profile 15 formed from flat sheet metal 5 in a cross section 14 orthogonal to the longitudinal direction 30, the body rail 2 and the drawer rail 3 being produced by a method for producing a rail 1 for the drawer pull-out guide 4, which is explained in more detail according to FIGS. 3a to 7c. Fig. Lb differs from Fig. La only in that the carriage was removed for purposes of illustration. As a result, a punching out of the drawer rail 3 can be seen, which is materially connected to two orthogonal profile surfaces 40 and serves both as a stiffener and as a stop for the carriage.

2a shows the arrangement of a drawer rail 3 and a cabinet rail 2 in a partially extended position. The profile 15 of the carcass rail 2 comprises six embossings 41 oriented orthogonally to a longitudinal extension 6 of the metal sheet 5 to reinforce the profile 5, with two groups of embossings 41 each being provided, which alternate in the direction of an inner area 42 and in the direction of an outer area 43 of the profile 15 are arranged. In general, however, just one group and/or groups of two or more alternating embossings 41 is also possible.

The body rail 2 and the drawer rail 3 are each folded into a fold 21 in the area of two profile surfaces 40 of the profile 15 . In general, only one rail 1 can have folds 21 and/or only include one or more fold(s) 21 . The folds 21 can be generated before, after and/or preferably during a bending process of the profile 15.

The carcass rail 2 comprises a fastening section 32 with a fastening side 33 which can be brought into contact with the furniture carcass or the at least one furniture part when it is mounted on the furniture carcass. The fastening section 32 comprises four circular openings 35 for the passage of a fastening means 36 in the form of a screw. The openings 35 are surrounded by a bead 39 on a second side 38 spaced apart from the fastening side 33 by a material thickness of the fastening section 32 - which can generally deviate from the wall thickness 20 of the metal sheet. Punching in the end area of the body rail 2, which protrudes through the fold 21, prevents the profile 15 from gaping (enlargement of an angle between side surfaces 9) in a particularly effective manner, with the beading 41 of the body rail 2 and the drawer rail 3 also preventing the rails from gaping by increasing a section modulus of the profile 15 or a stability/strength of the profile 15 and deformation—in particular in the longitudinal direction 30—of the profile 15 inhibit.

In general, two stampings are provided on both end regions of the carcass rail 2, which can be used to connect the carcass rail 2 to a piece of furniture, with one stamping particularly preferably being oriented orthogonally to the side surface 9 and another stamping through a bend parallel to the side surface 9 is arranged.

2b shows an enlarged detail of the drawer rail 3 of the drawer pull-out guide 4. The profile 15 of the drawer rail 3 comprises an embossing 41 which extends over two orthogonal profile surfaces 40. FIG.

In general, at least one end surface 17 and preferably both end surfaces 17 of the profile 15 of the drawer rail 3 and the body rail 2 (see FIG. 2a) are designed with a taper 16 (see FIG. 6); these are not visible in the illustration for reasons of clarity.

Fig. 3a explains the method for producing a rail 1, wherein a flat metallic sheet 5 with a longitudinal extent 6, two cover surfaces 7 and two side surfaces 9 spaced apart by a width 8 of the sheet 5 is provided as a semi-finished product 10 of the rail 1, the sheet 5 is in this embodiment at both

Cover surfaces 7 provided with a notch 13, wherein the Notches 13 are arranged orthogonally to the longitudinal extension 6, the metal sheet 5 is bent so that the profile 15 of the rail 1 is formed in a cross section 14 orthogonal to the longitudinal extension 6 and the bent metal sheet 5 is mechanically separated in the area of the notches 13, the rail 1 of the remaining material - which can be used for the production of further rails 1 - can be broken off mechanically by buckling for division.

The metal sheet 5 is made of steel. In general, however, aluminum or the like, for example, is also usable. It is also conceivable to make only one notch 13 in the metal sheet 5 and/or to arrange the notch 13 at an angle other than 90° relative to the longitudinal extent 6 in order to form the rail without cutting and without waste.

Two possible geometric configurations of the notch 13 can be seen in a sectional view, with a notch 13 in the form of a groove 22 with a notch cross section 25 parallel to the longitudinal extent 6 in the form of an elliptical segment 27 and a notch 13 in the form of a profile 23 as a triangle 19 in the notch cross section 25 was introduced into the metal sheet 5 with an opening angle 24 of 60°.

The sheet metal 5 has a wall thickness 20 of 0.7 mm.

3b shows an enlarged detail of the metal sheet 5 with the preferred geometry of the notch 13, the notch 13 having a notch cross section 25 parallel to the longitudinal extension 6 of the sheet metal 5 in the form of a trapezoid 26. The two notches 13 connect both side surfaces 9 of the metal sheet 5 and are arranged on the two cover surfaces 7 of the sheet metal 5 opposite one another and in a direction orthogonal to at least one of the two cover surfaces 7 one above the other. 3c shows the two indentations 13 from the side, with generally exactly four indentations 13 arranged in pairs on the two cover surfaces 7 being made in the flat metal sheet 5 for each rail 1 in order to break off the rail 1 twice in succession via the four indentations 13 of the bent sheet metal 5 to form. The sheet metal 5 can be provided with a large number of indentations 13 arranged in pairs on the two cover surfaces 7, so that a large number of rails 1 can then be broken off mechanically.

In this embodiment, 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.

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.

4b shows that the bent metal sheet 5 was mechanically separated at the two superimposed indentations 13 by breaking off via kinks and parts. The rail 1 was thereby formed with a burr-free taper 16 on one end surface 17 of the profile 15, with the second end surface 17 generally also being generated in this way. The remaining profile material already has the taper 16, which can be used without post-processing for a subsequent rail 1, with a post-processing step such as filing or grinding being generally provided in order to adapt the shape of the taper 16 or, if necessary, to remove unwanted elevations.

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. In general, as a result of the non-cutting separation process via plastic deformation, a bead-shaped end section can remain on the taper 16 or the taper cross-section 18 can be convex or concave. However, 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. However, pulling the rail 1 away from the remaining profile material is also conceivable. 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 .
