Abstract
Description
- This application claims priority of U.S. Provisional Patent Application Ser. No. 60/586,009 filed Jul. 7, 2004, entitled “Method of Inserting Structural Support Member in Roll-Formed Part” and U.S. Provisional Patent Application Ser. No. 60/588,118 filed Jul. 14, 2004, entitled “Reinforcement for a B-Pillar of an Automotive Vehicle.”
- This invention relates generally to the manufacture of reinforced structural components such as frame members for motor vehicles. More specifically, the invention relates to a method for incorporating a support member in such a component. In particular, the invention relates to a process for incorporating a reinforcing support member in a roll-formed component.
- The structural integrity of the passenger and cargo compartments of a motor vehicle relies upon the use of support pillars and other frame members. These structural components require a combination of high strength and light weight. Furthermore, in order to provide for the dissipation of energy in the event of a crash, these components should exhibit controlled and reliable deformation properties. The prior art originally utilized pillars and other structural components which comprise tubular or channel-like members of various cross-sectional configurations. However, the art subsequently turned to structural components having separate support members, also referred to reinforcement inserts, disposed therein. In some instances, these support members were inserted into pillars and the like after fabrication. For example, prior art U.S. Pat. Nos. 5,219,197 and 6,406,077 show methods wherein a support is inserted into the interior of a fabricated beam. Another approach is shown in U.S. Pat. No. 5,385,375 wherein a body of foamable polymeric material is injected into the interior volume of a beam and permitted to expand to form a polymeric insert. In another approach shown in U.S. Pat. No. 6,733,040, a two-piece beam is utilized, and an insert is placed therein and the two separate beam portions are then joined together.
- These prior art approaches are difficult to implement since they require that an insert be placed into the interior of a closed beam, or they require that an insert be installed into a two-part beam which process requires subsequent joining of the beam components. Such processes are not compatible with high speed, and in some instances, continuous, manufacturing processes which are generally favored for the fabrication of such components. Therefore, there is a need for a method for manufacturing reinforced pillars, frame members, and other structures, which method is simple to implement and compatible with high-speed fabrication processes such as roll forming.
- As will be explained in detail hereinbelow, the present invention provides a method for the fabrication of reinforced structures such as beams, pillars, and the like. The method of the present invention does not require that an insert be placed into a closed profile of a finished beam, nor does it require the use of multipart beams. As will be explained in detail hereinbelow, the present invention temporarily affixes a reinforcing support member to a body of material at an intermediate stage in its processing, and this combination is subsequently subjected to further processing to form a single part beam member having a reinforcing support member fixedly retained thereby. The method of the present invention may be readily implemented in conjunction with a high speed, preferably continuous, roll-forming process. These and other advantages of the present invention will be apparent from the drawings, discussion and description which follow.
- Disclosed herein is a method for manufacturing a reinforced structural component. In a first step of the method a body of sheet material, such as a body of sheet steel, is subjected to a first forming operation which shapes it into an intermediate structural member. The intermediate structural member defines a channel which extends along at least a portion of its length. In a separate step, a reinforcing insert or other such support member is provided. This support member is disposed in the channel of the intermediate structural member and affixed thereto so that it is retained in said channel. In a subsequent step, a second forming operation is carried out on the intermediate structural member having the support member retained therein. The second forming operation at least partially encloses and fixedly retains the support member within the channel. In particular instances, at least one of the first and second forming operations are a roll-forming operation.
- In particular instances, the step of affixing the support member to the intermediate structural member comprises a mechanical affixation step which may employ tabs, toggles, piercings, deformations and the like so as to secure the support member. In other instances, the support member may be adhered by adhesives, or by welding or brazing.
- In some instances, all or part of the structural component may be subjected to a further processing step, and this processing step may take place before or after the second forming operation. Such further processing steps may include sweeping, bending, die forming, welding, cutting, crushing, heating and/or quenching.
- The method of the present invention is compatible with continuous, roll-forming processing, and in some instances, an additional cutting step may be implemented either before or after the first or second forming operation.
- Also disclosed herein are articles made according to the process of the present invention.

While the present invention will have utility in the fabrication of metallic and nonmetallic components, it will find particular advantage in fabrication of structural components which include metallic portions. In particular, the present invention is readily adapted for use in high speed metal forming operations such as roll forming.
- The present invention will be explained with reference to
FIGS. 1A-1E which are schematic depictions of a general process according to the present invention. The process starts, as is shown inFIG. 1A , with a body of asheet material 10. Thesheet material 10 may comprise a ferrous or nonferrous metal, or it may comprise a body of another deformable material such as a polymeric material. As illustrated inFIG. 1 , the body ofsheet material 10 is shown as being a discrete body of material; however, it is to be understood that in many instances, the sheet material may be provided as an elongated web of material such as a body of coiled steel stock or the like. In some instances, the material will be cut into discrete sheets before subsequent forming, while in other instances, forming operations may be carried out, on a continuous basis, on the elongated web of material. - In any instance, the body of
sheet material 10 is subjected to a first forming operation which alters at least the cross-sectional profile of the body ofmaterial 10 so as to form an intermediatestructural member 12 as is shown inFIG. 1B . The intermediatestructural member 12 is configured so as to define achannel 14 which extends along at least a portion of the length of the intermediatestructural member 12. In the illustrated embodiment, thechannel 14 is defined by two turned-upsidewalls structural member 12. However, other forming operations such as stamping, bending, and the like may also be used in the practice of the present invention. - As is shown in
FIG. 1C , asupport member 20 is provided. Thismember 20 serves as a reinforcement in the completed structural component of the present invention. Thesupport member 20 is shown inFIG. 1C as having what is generally referred to in the art as a “hat” configuration; but, support members having other configurations, including closed profiles, may be utilized in the practice of the present invention. Thesupport member 20 may be comprised of a body of a ferrous or nonferrous metal, but in other instances the support member may comprise a body of polymeric material, including foamed or foamable polymeric material, or it may comprise a composite of organic and inorganic materials. In some particular instances, the support member may be a metallic member formed by a high-speed forming process such as roll forming. Accordingly, it will be appreciated that a wide variety of support members may be employed in the practice of the present invention. - In a subsequent step of the present invention, as is shown in
FIG. 1D , thesupport member 20 is disposed within thechannel 14 of the intermediatestructural member 12, and occupies substantially all of the length of thechannel 14. However, in other embodiments of the present invention, thesupport member 20 may occupy only a portion of the length of thechannel 14; and in yet other embodiments, a plurality of support members may be disposed in the channel. In any instance, thesupport member 20 is affixed to the intermediatestructural member 12 so as to be at least temporarily retained therein during subsequent processing. Such affixation may be by mechanical means, adhesive, welding, brazing or the like. - Referring now to
FIG. 2 , there is shown a cross-sectional view of an intermediatestructural member 12 together with asupport member 20 which is in the process of being disposed in thechannel 14 thereof. As will be seen fromFIG. 2 , a first body of adhesive 22 and a second body of adhesive 24 are disposed on the flange portions of thesupport member 20, and theseadhesive bodies support member 20 to the intermediatestructural member 12. Such adhesives may comprise contact adhesives, hot melt adhesives, curable adhesives or the like. - Referring now to
FIG. 3 , there is shown a cross-sectional depiction of another embodiment of intermediatestructural member 12 which has asupport member 20 retained therein by means oftabs structural member 12. Thesetabs channel 14 and allow thesupport member 20 to be snapped into place. Yet other configurations may be employed to mechanically affix the support member to the intermediate structural member. For example, as is shown inFIG. 4 , asupport member 20 includesflange portions 30, 32 which engage thesidewalls structural member 12 and slightly deform so as to provide an interference fit which retains thesupport member 20 in thechannel 14. In yet other instances, other mechanical affixations such as toggles, piercings, and the like, as well as welds or brazed joints, may be utilized to affix the support member in the channel of the intermediate structural member. It should be noted that any such affixation need only have temporary integrity, since subsequent processing will fixedly join the members. Therefore, short term adhesive bonds or relatively simple mechanical joints may be employed. - Referring now back to
FIG. 1E , there is shown a further step in the process of the present invention. Specifically,FIG. 1E shows a completed reinforcedstructural component 40 which is resultant from carrying out a second forming operation on the structure ofFIG. 1D , namely the intermediatestructural member 12 having thesupport member 20 affixed thereto. In theFIG. 1E illustration, portions of thesidewalls structural member 12 have been folded over so as to define a closed structure which fixedly retains thesupport member 20 therein. In the illustrated embodiment, the two edges of thesidewalls seam 42; this seam may be closed in a subsequent operation, such as by welding, although this step is optional. In yet other embodiments, the intermediate structural member may be otherwise shaped in the second forming operation, provided that such shaping causes it to fixedly retain the support member therein. This second forming operation may comprise a roll-forming operation, a bending operation, or any other such forming operation. - In some instances, the finished component, or members comprising it, may be subjected to further processing. For example, as is shown in
FIG. 5 , thecomponent 40 ofFIG. 1E is further shaped in a sweeping process so as to provide it with a transverse curvature. In other instances, further processing may involve bending, twisting, crushing portions of the structure, piercing, drilling, welding, cutting or the like. In yet other instances, further processing may involve heat treatments. For example, the thus fabricated structure may be subjected to a heating and die forming process. Likewise, the component may be subjected to a heat treatment process such as the process of heating and quenching. In other instances, the intermediate structural member may be subjected to such further processing before it is shaped in the second forming operation, and such processing may take place either before or after the support member is affixed. As will be appreciated by those of skill in the art, various processes may be utilized in conjunction with one another. - Other modifications and variations of the general process presented herein will be readily apparent to those of skill in the art. While
FIG. 1E shows thestructural component 40 resultant from the second forming step as having a completely closed profile, other such profiles including partially closed profiles may be likewise employed.FIG. 6A andFIG. 6B show the cross section of yet another structural component made in accord with the principles of the present invention. As is shown inFIG. 6A , asupport member 42 is disposed in an intermediatestructural member 12 generally similar to that ofFIG. 1B . Thesupport member 42 has a relatively tall profile which extends across a major portion of the height of thechannel 14.FIG. 6B shows the assembly ofFIG. 6A following the implementation of the second forming operation, which operation involves turning down portions of thesidewalls structural member 12. As is shown inFIG. 6B , thesesidewall portions support member 42 to project therebetween. As such, the support member is only partially enclosed within thechannel 14, but it cannot be removed without cutting or deforming and hence it is fixedly retained. - While the support member has been shown as having a relatively simple hat profile, it is to be understood that numerous other embodiments of support member may be utilized in the practice of the present invention. Such support members may comprise metallic as well as nonmetallic components, and as noted above, in some instances, may comprise foamed or foamable polymeric bodies as well as composite materials. Also, the support members may have cross sections which vary along their length, or are otherwise irregular, depending upon particular applications. Also, the intermediate structural member may be variously configured as discussed above. In some instances, the support member may be a body of a self-adhesive polymeric material, such as a foamable or non-foamable adhesive; in such instances the step of disposing the support member in the intermediate structural member and the step of affixing the support member may be carried out simultaneously.

FIGS. 7A and 7B depict yet other embodiments of the present invention. As shown inFIG. 7A , an intermediate structural member, which in this instance comprises a simple channel structure of the type shown inFIG. 1B , has a support member disposed in thechannel 14 thereof. Thesupport member 50 has a generally triangular-shaped cross section with twoflange portions FIG. 7A , theflange portions sidewalls flanges sidewalls sidewalls flanges - Yet other embodiments may be implemented in accord with the present invention. For example,
FIG. 8A shows an intermediatestructural member 60 which defines a V-shaped channel. Asupport member 62 having a cylindrical cross section is affixed therein, and as is shown inFIG. 8B , portions of the sidewalls of the V-shaped intermediatestructural member 60 are folded inward so as to retain thesupport member 62 and thereby define astructural component 64. - The present invention may be implemented in yet other configurations and embodiments. The process of the present invention is readily adapted for high speed manufacturing processes, and is particularly adaptable to processes utilizing sheet steel. Structures of the present invention are simple to manufacture, and have very high strength owing to the reinforced structure thereof. Through the use of lightweight hardenable steels, in conjunction with heat treating or other post forming hardening processes, lightweight, high-strength members such as motor vehicle pillar assemblies, bumper bars, intrusion beams, and the like may be readily fabricated. While this invention has been described primarily with reference to components of motor vehicles, it may likewise be employed to fabricate other structures such as buildings, and other articles of manufacture in which structural components having high strength and light weight are desired.
- The foregoing drawings, discussion and description are illustrative of some specific embodiments of the present invention, but are not meant to be limitations upon the practice thereof. Yet other modifications and variations thereof will be readily apparent to those of skill in the art. It is the following claims, including all equivalents, which define the scope of the invention.
