Abstract
Description
- The present invention relates generally to a method for making an automotive headliner and more particularly to a method for making a punched automotive headliner.
- Vehicle headliners are commonly utilized in automotive design and construction in order to improve the appearance of the inside of the automobile. In addition, headliners may be utilized to provide sound absorption in order to improve passenger comfort. Headliners are preferably lightweight and rigid and may be mounted to the roof in a variety of fashions. They commonly must accommodate a variety of features such as sunroofs, lighting, entertainment features, ventilation, and most recently safety features.
- As the resultant complexity of the vehicle headliner form has increased in response to these features, so too has the complexity of manufacturing the headliner. Traditional punch methodologies utilized to generate proper form in a headliner blank can experience undesirable fatigue when utilized to continuously generate orifices within the blank to accommodate these features. Traditional punch methodologies place the headliner blank within a punch tool between a punching component and a mating component. The punching component is pressed towards the mating component until it punches through the headliner blank and contacts the mating component. This in turn removes waste from the headliner blank and thereby forms the desired orifices and other shapes.
- It is known, however, that repeated engagement of the cutting edge on the punching component with the mating component can serve to dull the cutting edge and reduce its effectiveness. In short term degradation, this may negatively impact the quality of the sheared edge of the headliner which in turn may impact installation and customer satisfaction. Over longer term degradation, the cutting edge may experience greater difficulty in effectuating the punch itself and may require replacement. Such replacement requirements can impact manufacturing costs, which in turn impact the part and automotive cost basis. A more robust punch methodology that preserved the cutting edge over greater usage could be utilized to provide improvements to the manufacturing costs.
- In addition to the robustness of punch tooling, existing methodologies leave room for improvement in the headliner design. Commonly, in areas surrounding the outer edge of the headliner or feature areas, the headliner blank material is bent to generate a flange. These flanges may be utilized for both appearance as well as assembly considerations. Often it is required that an additional support element be bonded to these flanged areas of the headliner blank such that structural rigidity is preserved and mounting strength is generated. The dual material throughout the generated flanged area can serve to increase the weight of the headliner assembly. This, in turn, effects both cost as well as fuel efficiency of the vehicle. An improved headliner design that minimized material overlap between the headliner blank and support element could be utilized to both reduce weight and lower costs.
- It would therefore be highly desirable to have a new method for producing automotive headliners that improved machining robustness. It would further be highly desirable to have an automotive headliner with improved weight savings.
- It is therefore an object of the present invention to provide a method of producing a punched headliner with improved reliability. It is a further object of the present invention to provide an automotive headliner with reduced weight.
- In accordance with the objects of the present invention a method for making a punched headliner adapted to be installed in a motor vehicle is provided. The method includes placing a flange element within a punch tool, the punch tool comprising a punching component and a mating component. The flange element is placed abutting the mating component.
- A headliner blank is placed within the punch tool between the punching component and the flange element. A punching edge, positioned on the punching component, is moved towards the mating component. The headliner blank is thereby pressed between the punching edge and the flange element. The punching edge is pressed into contact with the flange element such that a shearing edge is formed on the headliner blank and a waste component is separated from the headliner blank.
- Other objects and features of the present invention will become apparent when viewed in light of the detailed description and preferred embodiment when taken in conjunction with the attached drawings and claims.

FIG. 1 is an illustration of an apparatus for the production of punched headliner's in accordance with the present invention, the apparatus illustrated in the loaded position. -
FIG. 2 is an illustration of the apparatus illustrated inFIG. 1 , the apparatus illustrated in the compressed position. -
FIG. 3 is an illustration of the automotive headliner manufactured inFIG. 2 . - Referring now to
FIG. 1 , which is an illustration of an apparatus and method for manufacturing punchedheadliners 10 in accordance with the present invention. Theapparatus 10 includes a punching tool 12 comprised of apunching component 14 and amating component 16. Punching tools 12 are utilized in order to form shapes into headliner blank 18 material in order to produce practical headliner assemblies 20 (seeFIG. 3 ), or similar punched product assemblies, for installation into automobiles. The punching tool 12 includes amaterial gap 13, for part materials, when in theopen position 15. The punching tool 12 closes thematerial gap 13 by moving thepunching component 14 into the closed position 17 (seeFIG. 2 ). Thepunching component 14 includes apunching edge 22. Knownpunching edges 22 andcomponents 14 are commonly comprised of hardened metal. When they continuously impact into themating component 16 themating component face 24 can wear out and thepunching edge 22 may begin crushing into themating component face 24. This results in undesirable wear on the punching tool 12. - The present invention, however, utilizes a unique punching tool 12 and methodology in order to improve wear characteristics of the punching tool. The present invention includes a
mating component 16 comprised of avertical engagement surface 26, a roundedmating transition edge 28 and an upperhorizontal mating surface 30. Aflange element 32 is positioned within the punching tool 12 and is placed abutting themating component 16. Although it is contemplated that theflange element 32 may be inserted in a variety of shapes and conditions, in one embodiment theflange element 32 includes anarched transition portion 34 connecting avertical extension 36 to ahorizontal mounting section 38. Theflange element 32, therefore, conforms to themating component 16. It should be understood, however, that theflange element 32 may be conformed to themating component 16 during punching operations in alternate embodiments. It should further be understood that thevertical extension 36 is not required to be completely vertical but preferably is angled in relation to thehorizontal mounting section 38. In addition, asecond flange element 40 may be additionally placed abutting themating component 16 such that additional mounting capabilities are afforded theheadliner assembly 20. Amounting gap 42 may be formed in thesecond flange element 40, thefirst flange element 32, or both to provide fastener capabilities. - The headliner blank 18, or other material blank, is positioned within the punching tool 12 such that the
flange element 32 is positioned between the headliner blank 18 and themating component 16. The headliner blank 18 is further positioned such that it is between theflange element 32 and apunching edge 22 formed on thepunching component 14. Thepunching edge 22, in turn, is positioned such that both the headliner blank 18 and theflange element 32 are positioned between thepunching edge 22 and themating component 16. In this fashion, thepunching edge 22 can punch through the headliner blank 18, thereby generatingwaste component 46, and impact the flange element 32 (seeFIG. 2 ). Since thepunching edge 22 impacts theflange element 32 rather than themating component 16, thepunching edge 22 impacts avirgin flange element 32 upon each operation (as anew flange element 32 and headliner blank 18 are inserted). This prevents the undesirable wear of themating component 16 and subsequent dulling of thepunching edge 22 experienced by known designs. - Although a variety of punching
edges 22 are contemplated by the present invention, one embodiment contemplates the use of a punchingedge 22 comprised of a firstangled edge 48, a rounded leadingsurface 50, and asecond edge 52. The punchingedge 22 is positioned such that the firstangled edge 48 generates ashearing edge 54 in theheadliner blank 18 and impacts theflange element 32, after shearing theheadliner blank 18, along thearched transition portion 34. It is contemplated that the punchingedge 22 should finish shearing theheadliner blank 18 prior to any portion of the punchingedge 22 contacting themating component 16. The punching edge 44 thereby generates a shearing edge radius ofcurvature 56 that forms a tangent with thearched transition portion 34 of theflange element 32. In this fashion, a contiguous surface is generated from the headlinerupper surface 58 to thevertical extension 36 of theflange element 32. This improves appearance and allows the flange elementvertical extension 36 to act as the sole vertical support for theheadliner assembly 10 rather that the combination of headliner blank 18/support 32 previously utilized. This allows for a reduction in weight of theheadliner assembly 20 or similar punched product assemblies. - Although the
flange element 32 may be attached to the headliner blank 18 in a process subsequent to the punching operations, in one embodiment it is contemplated that abonding material 60 may be positioned between thehorizontal mounting section 30 of theflange element 32 and the headlinerlower surface 62. This provides for theflange element 32 to be joined to the headlinerlower surface 62 during the punching operation and reduces the number of manufacturing steps. In addition, this embodiment helps ensure the alignment of theheadliner shearing edge 54 with theflange element 32. - While the invention has been described in connection with one or more embodiments, it is to be understood that the specific mechanisms and techniques which have been described are merely illustrative of the principles of the invention, numerous modifications may be made to the methods and apparatus described without departing from the spirit and scope of the invention as defined by the appended claims.
