Description

The present invention relates to a method for crimping and / or crimping at least one first component with a second component, to a semifinished product for forming a flanged assembly, to a flanged assembly and to a machine tool for producing a flanged assembly.

Beading is a common procedure for joining two or more components together. In this case, a specially shaped sheet metal part is bent so that the parts then can not fall apart.

Usually, when crimping the parts to be joined are pressed together and then fixed together in this state by crimping. By crimping the parts are pulled together so far that there is no gap between them, that is, they are "on block". Slight biasing forces that hold the parts together in a block are achieved by elongating the bent sheet metal parts when crimping.

The Utility Model DE 81 05 788 U1 discloses a sealed with a metal cover electronic control device with recessed housing edge portions cross attachment tabs. Depending on a fastening tab is pressed into a recess adjacent to the recessed edge portion of the housing recess, wherein a pointing away from the edge portion free end of the fastening tab is held on a back wall of the recess.

Against this background, the approach presented herein provides an improved method of crimping at least one first component with a second component, an improved crimped assembly forming pedestal, an improved crimped assembly, and an improved machine tool for producing a crimped assembly according to the main claims.

Advantageous embodiments will become apparent from the dependent claims and the description below.

A crimping of a plurality of components using a suitably pre-bent further component allows a connection of the components under a voltage that degrades by temperature expansion or contraction of the parts when cooled not or only slowly. This can be achieved by having resilient lengths, i.e. an elastic fraction of the sheet metal strain of the parts to be joined, which are sufficiently long.

An improved according to the approach presented here crimping can allow greater ways of thermal expansion and maintained over the entire temperature range necessary for the fixation of the parts clamping force. Thus, rattling or even falling apart of the flanged parts can be effectively avoided at low temperatures.

A method of crimping at least one first component with a second component comprises the following steps:
Providing a third component having a first connection portion and a second connection portion extending at a predetermined angle with respect to the first connection portion, wherein in the providing step, the third component is applied to the second component such that the first connection portion forms a common interface of the third Component and the second component lies flat against the second component and the second connecting portion extends away from the second component at the predetermined angle; and
Bending an end portion of the second connecting portion, wherein in the bending step, the end portion of the second connecting portion is bent around an end edge of the first component and / or an end edge of the second component until the end portion on the first component comes to rest around the first component To connect crimped with the second component.

The method can be carried out by a suitable machine tool, for example computer-controlled. The crimping connection can be understood as a connection technique in which components are positively connected by bending over a connecting element around at least portions of the components. The connecting element may be a separate element or a component of one or more of the components to be connected. In general, in this connection technique, the element used to make the connection is metal. The components to be joined may be formed of metal or plastic and stacked one above the other. For example, the first component and the second component may each be a printed circuit board or a printed circuit board and a cover for the printed circuit board. The first and the second component may be formed as straight or curved or stepped plates, which are to be placed flat on each other in at least one area and to connect crimping. Like the first and second components, the third component may be formed as a plate, which may have a bend and possibly further bends at the transition between the first and the second connecting portion. The third component may comprise a metal or be formed of metal. The first and second connecting portions may be formed by bending at the predetermined angle at a suitable position of the third component. The first and the second connecting portion may have different lengths. With the application of the third component to the second component, the second component can be sandwiched between the first component and the third component. In the application, the first connecting portion of the third component can be applied to a central region of the second component, so that the second connecting portion extends toward the end edge of the second component. The predetermined angle at which the second connecting portion extends away from the second component may be, for example, between five and forty degrees. Below the end edge of the first component and the end edge of the second component, one side of the components formed as plates can be understood as having a smaller area compared to the main sides expansion, which extends at right angles to the opposing main sides of the components. For example, the respective end edges can determine a height or thickness of the first or second component. As a result of the clinching, the end portion of the second connecting portion may abut on a first major side of the first member opposite to a second major side of the first member adjacent to the second member. Upon completion of the step of bending, the third component in the region of the second connecting portion can clasp the first and the second component in a U-shaped manner and thus connect to one another in a form-fitting manner. With the aid of the method, it is possible to create a full peripheral flanging of the first component with the second component. The flanging can also consist only in sections, for example on one or more sides of a stack of rectangular components.

According to an embodiment of the method, in the step of providing as the third component, a member may be provided in which the predetermined angle is in a range of one degree to 30 or 40 degrees. A bend between the first and the second connecting section in this angular range can, after the bending step, bring about a maximum prestressing in the second connecting section of the third component, by means of which the first and the second component can be optimally held together.

According to an embodiment, the method between the step of providing and the step of bending may include a step of bending the second connection portion toward the second component. Thus, a contact point spaced from the common interface between the second component and the third component can be created. The point of contact between the second and third components may be near the end edge of the second component and proximate to the junction marked by a bend between the first and second connecting portions of the third component. With this method step, the advantageous bias voltage for holding together the first and second component can be produced in a simple manner.

In particular, in the step of bending, a void may be formed between the common interface and the point of contact. Also with this embodiment in the form of the cavity, the bias voltage for the fixed connection of the first to the second component can be easily produced and maintained.

According to a further embodiment, in the step of providing as the third component, a component may be provided in which the second connection portion has at least a first portion and a second portion which are arranged at a further predetermined angle to each other, wherein in the step of bending a portion of the second portion is bent as the end portion, and wherein the second portion is farther than the first portion from the first connection portion. The subdivision of the second connection section into the first and second subsections can also be produced by means of a material bend. In this case, the resulting additional angle between the two sections can be greater than the angle between the first and the second connecting section. For example, this further predetermined angle may be 90 degrees or in the range of 90 degrees. In particular, the bending around this further predetermined angle may be a bending of the third component towards the end edges of the first and second component, based on the arrangement of the third component with respect to the second and first component after the first connecting portion has been applied to the first component second component. The first and second sections may be the same or different lengths. With this method step, the final step of the bending can be advantageously prepared by already taking place a suitable preforming of the third component. With the optimal choice of a size of the further predetermined angle and the bias voltage can be further increased.

In particular, in the crimping step, a flanging of the end edge of the first component and the end edge of the second component can be produced by means of the third component. This connection technology enables a particularly secure, robust and easy-to-reach connection of the first component with the second component. It is particularly advantageous that can be completely dispensed with additional elements such as clamping or screw elements.

A semifinished product for forming a flared assembly comprises a first component, a second component and a third component, wherein the second component is sandwiched between the first component and the third component, and wherein the third component has a first connection portion and one at a predetermined angle opposite the first connecting portion extending second connecting portion and rests against the second component, that the first connecting portion and the second component form a common interface, while the second connecting portion extends at the predetermined angle away from the second component, wherein the second connecting portion of a End edge of the first component and an end edge of the second component facing.

Such a semi-finished product can be produced by simple means by carrying out the method described with reference to the preceding embodiments.

According to one embodiment of the semifinished product, the third component may have a smaller width than the first component and / or the second component. Thus, only a partial connection of the first with the second component can be realized. Such a section-wise connection can be designed so that in a rectangular assembly - consisting of the first, the second and the third component - the flanging invention is formed only on one side. For this purpose, the entire third component or only the second connecting portion or also the first and second connecting portion can be made narrower in the region of the later flanging than the first and second component. To stabilize the crimping can be realized on a side opposite the other side. In this embodiment of the semifinished product, the connection of the first component to the second component can be brought about particularly quickly and cost-effectively.

A flanged assembly using a semifinished product according to one of the preceding embodiments is characterized in that an end portion of the second connecting portion is bent around the end edge of the first component and the end edge of the second component, wherein the end portion rests on the first component and wherein between the second Component and the third component, a cavity is formed.

A machine tool for producing a flanged assembly has the following features:
a device for providing or supplying at least a first component, a second component and a third component, wherein the third component has a first connecting portion and a second connecting portion extending at a predetermined angle with respect to the first connecting portion;
a device for applying the third component to the second component in such a way that the first connecting portion for forming a common interface of the third component and the second component is applied flat against the second component and the second connecting portion at the predetermined angle of the second component extends away; and
means for bending an end portion of the second connection portion to abut the end portion on the first component to make the crimped assembly.

The machine tool can be designed to suitably carry out a method for crimping at least one first component with a second component according to one of the above-explained embodiments in their devices and to produce a crimped assembly in accordance with the above-described embodiment or its semifinished product.

A computer program product with program code which can be stored on a machine-readable carrier such as a semiconductor memory, a hard disk memory or an optical memory and is used to carry out the crimped connection according to one of the embodiments described above if the program is installed on a computer is also of advantage or a device is executed. For example, a corresponding computer or a corresponding device for carrying out the method can be suitably coupled to the machine tool described above in order to carry out the method suitably by means of the devices of the machine tool.

In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and similarly acting, wherein a repeated description of these elements is omitted.

1 shows a cross-sectional view of a portion of an embodiment of an inventive crimped assembly 100 with an identification of the different voltage ranges of the module 100 , In the 1 Sectionally shown module 100 includes a first component 102 , a second component 104 and a third component 106 , At the in 1 the embodiment shown is in the first component 102 around a lid of the assembly 100 , at the second component 104 around a circuit board of the assembly 100 and at the third component 106 around a bottom of the assembly 100 , Alternatively, the components can 102 . 104 . 106 also fulfill other functions.

Like the illustration in 1 shows is the second component 104 executed as a flat plate. The first component 102 is stepped and lies in one edge area on block on the second component 104 on. The third component 106 is also stepped and encompasses the first component 102 and the second component 104 from below and forms in a U-shaped encompassing edge regions of the first component 102 and the second component 104 a flanging of the first component 102 with the second component 104 ,

At the finished beaded assembly 100 as they are in 1 are shown, there are various - indicated in the diagram - voltage ranges, which refers to a durability of the crimped connection of the components 102 . 104 . 106 impact. Here comes the third component 106 a central role too. It must be shaped in a certain way to provide a bias to hold the assembly together 100 contribute. The third component 106 can be divided into several areas. A marked by an ellipse first area 108 of the third component 106 is by a step-like bending of the third component 106 marked and forms the actual housing function. A second area marked by another ellipse 110 of the third component 106 fulfills the function to build up the bias. This second area 110 is in particular by a first connecting portion 112 and a second connecting portion 114 of the third component 106 whose meaning is discussed in more detail with reference to the following figures. In a third area marked by another ellipse 116 of the third component 106 will be in the second area 110 built-up bias on the remaining parts 102 . 104 the assembly 100 forwarded. A fourth area 118 indicates another bias range.

The areas 108 and 110 , which map the housing function, are constructed similar to the prior art in order to meet the protective function of the housing can. The inventive special design of the third component 106 especially in the third area 116 , With reference to the following figures are based on individual phase images of a method for producing the flanged assembly 100 explains the inventive features for introducing the required bias.

In the 1 The illustration shown shows by way of example how a detail of a housing assembly flanged according to the approach presented here 100 can look like. Only the cross section is shown on one side. According to embodiments of the concept presented here are such crimps around the entire housing of the assembly 100 arranged around. Alternatively, the assembly 100 also more or less components than the one in 1 have shown embodiment.

2 shows a cross-sectional view of a phase of a method according to the invention for crimping connecting at least one first component with a second component to form the flanged assembly 1 , In the illustration in 2 is a semi-finished product 200 the in 1 illustrated exemplary assembly.

The phase diagram shows the arrangement of the semifinished product 200 after the step of providing the first component 102 , the second component 104 and the third component 106 , This is the first component 102 on the second component 104 in an edge region of both components 102 . 104 placed in a block, that is, in the edge region are the flat portions of the first component 102 and the second component 104 flat loosely on each other, are not yet compressed. An end edge 202 of the first component 102 and an end edge 204 of the second component 104 are not quite flush, because the second component 104 something in the direction of a center of the semifinished product 200 withdrawn. The end edges 202 . 204 be through side surfaces of the components 102 and 104 formed, which have a smaller area than the respective main sides, where the three components 102 . 104 . 106 adjoin one another.

The third component 106 is with its first connecting section 112 to the second component 104 on a main side of the second component 104 created, which is another main page, which is attached to the first component 102 adjacent, opposite. With a successful application forms the first connection section 112 a common interface 205 with the second component 104 , This is the second component 104 sandwiched between the first component 102 and the third component 106 arranged. The first connection section 112 lies flat against the second component 104 at. Like the illustration in 2 shows, the first connection section 112 and the second connection portion 114 by a bend of the third component 106 formed at a predetermined position. The first connection section 112 and the second connection portion 114 are thus formed integrally with the third component and formed only by a material deformation.

Due to the bending, which in an early process step for producing the flanged assembly from 1 can be generated, the second connection section runs 114 at a predetermined angle 206 opposite the first connecting portion 112 so that with successful creation of the first connection section 112 to the second component 104 the second connection section 114 at the predetermined angle 206 from the second component 104 - in the representation down - away away. The predetermined angle 106 must not be too large and not too small to cause a plastic deformation at the bending point at a later step of bending back of the second connecting portion, which ensures a maximum bias for fixing the components. At the in 2 shown embodiment of the semifinished product 200 is the angle 206 in the rough range between 30 and 40 degrees.

Like the illustration in 2 shows is the second connection section 114 longer than the first connection section 112 and further away from a center of the semifinished product 200 as the first connection section 112 , In particular, the second connection section 114 through a first subarea 208 and a second subarea 210 characterized. The first section 208 and the second subarea 210 Be through another material bend to another predetermined angle 212 , created. The further predetermined angle 212 is greater than the predetermined angle 206 , The bend of the third component 106 around the further predetermined angle 212 is required to the third component 106 in addition to the bias structure in a suitable form to bring to beading. Like the illustration in 2 shows, the further predetermined angle 212 between the first subarea 208 and the second subarea 210 Approximately 90 degrees, it can alternatively be larger or smaller.

With application of the third component 106 to the second component 104 in the manner described above, it turns out that as a result of the bending around the predetermined angle 206 the third component 106 from the second component 104 extends away while the third component 106 due to the bend around the further predetermined angle 212 again to the second component 104 extends, in particular to the end edges to be flanged 202 . 204 of the first component 102 or second component 104 , It is also good to see that the second section 210 further than the first subarea 208 from the first connection portion 112 is removed. With the described application of the third component 106 extends the second portion 210 something about a block-lying surface of the first component 102 and thus a surface of the semifinished product to be flattened 200 In addition, at a later stage of the manufacturing process, the flanging by simply bending over an end portion 214 of the third component 106 can be accomplished.

The representation in 2 shows with the semi-finished product 200 the assembly to be flattened out 1 thus in a preassembled condition. Especially is the third component 106 im in the 1 marked third area, ie in the region of the second subarea 210 bent so that it in the third area and also in the means of the further predetermined angle 212 marked fourth area of the remaining components 102 . 104 projects.

3 shows a plan view of the semifinished product 200 in the manufacturing phase 2 , A section line AA marks the cross section through the semifinished product 200 who in 2 is shown. From the top view is clearly visible, as the third component 106 in this manufacturing phase before flanging against the first component 102 and the second component 104 protrudes.

4 shows on the basis of a further cross-sectional view of a further phase in the inventive method for crimping connecting at least a first component with a second component to form the crimped assembly from 1 , In the illustration in 4 is like in 2 a section of the semifinished product 200 shown. 4 shows the exemplary semi-finished product 200 after a step of bending the second connection portion 114 towards the second component 104 , In this step of bending becomes the first subarea 208 of the second connection portion 114 of the third component 106 until it stops against the second component 104 pressed. The bending is carried out until one of the common interface 205 spaced contact point 400 between the second component 104 and the third component 106 is created. Accordingly, between the touch point 400 and the beginning of the common interface 205 a small cavity 402 between the second component 104 and the third component 106 educated.

Furthermore, the illustration in FIG 4 , as a result of bending, the second portion 210 of the second connection portion 114 to the end edge 202 of the first component 102 invests. Because the end edge 204 of the second component 104 is retracted by a small amount, with the application of the second portion 210 and the first component 102 another cavity 404 between the second component 104 and the third component 106 educated.

The representation in 4 shows with the semi-finished product 200 the assembly to be flattened out 1 thus in a pre-pressed state. The externally applied clamping force with the bending process described above acts on the semifinished product from two opposite directions 200 , One in the representation from below on the semi-finished product 200 acting force whose first direction of force 406 is marked by two arrows pointing upwards, and one from above on the semi-finished product 200 acting force whose second direction of force 408 marked by a downward arrow, press the assembly 200 so together, that the items 102 . 104 . 106 come to rest without play. Furthermore, this is the third component 106 introduced deformation again in the direction of the components to be crimped 102 . 104 bent.

It is not mandatory that the third component 106 im means of the further predetermined angle 212 marked fourth area the first component 102 or the second component 104 touched. That is, according to an alternative embodiment of the semifinished product 200 can next to the other cavity 404 a third cavity between the second portion 210 of the third component 106 and the end edge 202 of the first component 102 consist.

5 shows a plan view of the semifinished product 200 in the manufacturing phase 4 , A section line BB marks the cross section through the semifinished product 200 who in 4 is shown. From the top view is clearly visible, as the third component 106 in this production phase on the first component 102 and / or the second component 104 is applied.

6 shows on the basis of a further cross-sectional view of a further phase in the inventive method for crimping connecting at least a first component with a second component to form the crimped assembly from 1 , according to an embodiment of the present invention. The representation in 6 shows an embodiment of the finished flared assembly 100 after a step of bending the end portion 214 of the second connection portion 114 of the third component 106 , Like the illustration in 6 shows became the end section 214 so around the end edge 202 of the first component 102 and around the end edge 204 of the second component 104 bent over on one of the second component 104 facing away from the first main page 600 of the first component 102 came to the concern. This is the first component 102 and the second component 104 through the third component 106 connected with each other.

As shown in 6 After flanging, it remains in the third area, ie in the area of the now U-shaped second subarea 210 , introduced bias in the form of - again marked by arrows - clamping forces 406 and 408 persist and continue to pull the parts 102 and 104 together. The clamping forces 406 . 408 are so to speak "frozen" by means of the flanging technique presented here. The clamping forces 406 . 408 act starting from the third component 106 in the direction of the arrows shown and may be due to different forms of Design of the third component 106 be varied in a wide range.

At a - in 6 illustrated - ideal design is based on the representation in 2 explained predetermined angles of the bending of the third component 106 chosen so large that when bending back a plastic range of deformation is reached again. This can ensure that the maximum possible proportion of the elastic range for the introduction of the maximum clamping forces 406 . 408 is available.

7 shows a plan view of the finished beaded assembly 100 in the manufacturing phase 6 , A section line CC marks the cross section through the assembly 100 who in 6 is shown. From the top view is clearly visible, as after completion of the crimping of the end portion 214 completely bent over and on the first component 102 rests.

8th shows again in cross section the portion of the completed exemplary crimped assembly 100 out 1 , It is easy to see how the first component 102 and the second component 104 by beading by means of the third component 106 held together.

9 shows a perspective view of a section of a completed exemplary crimped assembly 100 in a limited in depth execution. The extent in depth can thus vary depending on the specification. The illustration clearly shows that the crimping of the first component 102 with the second component 104 through the third component 106 only over a partial area of one side of the module 100 extends. This is achieved by the third component 106 in at least one section, a smaller width than the first component 102 and the second component 104 having. The section reduced in width is the one in 9 shown embodiment of the module 100 around the second subarea 210 of the second connection portion 114 of the third component 106 , Alternatively, z. B. also the third component 106 in its entire width narrower than the other components 102 . 104 be executed. In the 9 Sectional crimping shown may also be on other sides of the assembly 100 be realized. Alternatively, the assembly 100 be completely crimped in the manner shown.

A combination with the usual flanging according to the prior art is possible. That is, portions of the assembly may be selected in which the flare is designed according to the concept presented herein, and portions of the product may be selected in which the conventional method is used. Both versions can be side by side on the same product.
