Detailed Description
The present disclosure details an exemplary roof ditch molding that includes a pre-formed notch prior to roll forming and extrusion to provide a finished end feature of the molding that does not require an end cap.
Referring to FIG. 1, a vehicle 10 has a roof 12 that includes a channel known as a roof ditch 14. Roof ditch 14 is a channel within roof 12 that directs water away from the sides of the vehicle and may also include attachment welds securing the roof to the vehicle. The ditch molding assembly 16 covers the roof ditch 14 and provides a desired aesthetic appearance and water management function.
Fig. 2 shows an apparatus 20 for manufacturing the roof ditch molding assembly 16. A method of manufacturing the roof ditch molding assembly 16 using the apparatus 20 includes first forming a flat metal strip 22, as shown in fig. 3. The apparatus 20 includes a cutting device that then forms a slot 24 in the flat metal strip 22 to provide a flat slotted strip 26, as shown in fig. 4. After forming the grooved strip 26, it is fed into a roll former to provide a profiled grooved strip 28, as shown in FIG. 5. Next, a flexible material 30 is extruded over the profiled grooved strip 28 to cover the profiled grooved strip 28 to provide a co-extrusion roll-formed roof ditch molding 32, as shown in fig. 6. The co-extrusion roll formed roof ditch molding 32 is then cut to a desired length to provide roof ditch molding 34 having cut ends 36 (FIG. 8A) at the slot locations 38 (FIG. 7) to provide tabs 40 at each cut end 36. The pattern 42 of flexible material 30 is removed from the slot 24 associated with the cut end 36, as shown in fig. 7. The tab 40 is then bent to provide a final shaped end 44 of the roof ditch molding assembly, as shown in FIG. 1.
In one example, the flat metal strip 22 is made of an aluminum material. In one example, the flexible material 30 comprises a plastic material. Other types of materials may also be used to shape the strip and provide a flexible cover material.
In one example, the process begins with unwinding a thin continuous aluminum strip 50 from a roll 52, as shown in FIG. 2. For example, a thin continuous aluminum strip 50 is unwound at a constant speed. The aluminum strip 50 is passed through a leveler or leveler 54 to ensure that the strip 50 is flat to provide a flat metal strip 22 (fig. 3). Next, the continuous flat metal strip 22 is passed through a take-up ring or restrictor 56 to regulate the material flow/velocity. This allows the flat metal strip 22 to be stopped (i.e., held in place) long enough to form the notches 24 in the strip 22 while maintaining a consistent unwind rate and providing a flat slotted strip 26.
To form the slot 24, the strip 22 is fed into a hydraulic punch 58 via rollers 60 and the strip 22 is stopped/held so that the slot 24 can be punched into the strip to form the flat slotted strip 26. Thus, at this point of the process, a continuous slotted strap 26 is provided, with the slots 24 spaced along the length of the strap 26 (fig. 4). The notches 24 are pre-punched to remove excess strip material prior to any extrusion or roll forming process.
In one example shown in fig. 4, the flat grooved strip 26 has opposite side edges 62 that extend along the length L of the flat grooved strip 26 and are spaced apart from each other by the width W of the flat grooved strip 26. In one example, the notches 24 are formed in pairs in each of the opposing side edges 62 such that the pairs of notches 24 are spaced apart from one another in a first direction along the length L of the flat slotted strap 26, with the notches in each pair of notches being aligned with one another in a second direction across the width W of the flat slotted strap 26. Thus, for example, a first pair of notches 24a, 24b are aligned with one another across the width W of the strap 26, and a second pair of notches 24c, 24d are aligned with one another across the width W of the strap 26, with the first pair of notches 24a, 24b being spaced apart from the second pair of notches 24c, 24d along the length L of the strap 26.
Next, the flat slotted strip 26 passes through another take-up ring 64 that is used to regulate the flow/speed of material to the roll former 66. The strip 26 passes through guides 68 that align the strip 26 for use in a roll former 66. The strip 26 is fed into a roll former 66 and converted from a flat strip to a profiled strip 28 using a series of rollers 70 as shown in figure 5. In one example, the roller 70 is configured to convert a flat strip into a profiled strip having C-shaped sections. The C-shaped section has a base portion 72 with flanges 74 extending upwardly away from opposite edges of the base portion 72.
Next, the profiled grooved strip 28 passes through a straightener 76 which straightens the profile and directs the profiled grooved strip 28 into an extruder 78. During extrusion, a flexible material 30, such as a soft plastic skin, is, for example, overmolded over the strips 28 to cover the C-shaped sections. In one example, soft green plastic material such as thermoplastic elastomer (TPE) or Thermoplastic Polyurethane (TPU) pellets, spheres, or powder is charged into a hopper 80 and then fed into a long heated cylindrical extruder 78. The material is moved through this extruder chamber by a rotating screw (not shown) and forced into an optional metering device 82, which may be used to control the material flow. The molten plastic is forced through a small opening that includes a die 84 to shape the finished product. The profiled grooved strip 28 passes through a die 84 and a thin layer of flexible material 30, e.g., about.5 mm thick, is extruded over the C-shaped section covering the entire profiled grooved strip 28. The strip then passes through a cooling device 86. Small fins or seals (not shown) may also be formed on each side of the extrusion if desired. This forms the co-extrusion roll-formed roof ditch molding 32.
Next, the co-extrusion roll formed roof ditch molding 32 is cut to a desired length with a die cutter 88 to provide the final roof ditch molding 34 having cut ends 36, as shown in fig. 8A. In addition, the original plastic overmold is trimmed to prevent wrinkling along the edges. In one example, excess plastic material is removed in a triangular pattern 42, as shown in fig. 7. The molding 32 is then cut at the center of the slot, as indicated at 90, which forms two tabs 40. One tab 40 is for the first final roof ditch molding 34 and the other tab 40 is for the second final roof ditch molding 34. Although a triangular pattern is shown, other patterns may be used to provide different tab configurations as desired.
Thus, the die cutter 88 not only die cuts the metal but also trims away excess flexible material along the edges of the profile. When excess material is trimmed away in the triangular pattern 42, a tapered surface 92 is provided that extends from each side edge of the final roof ditch molding 34 toward the distal end of the tab 40. The die cutter 88 then makes a center cut 90 and returns to grasp the next section of the co-extrusion roll formed roof ditch molding 32. The cut pieces are then transferred to an output station 94.
After the co-extrusion roll formed roof ditch molding 32 is cut to length and excess material is removed to provide the final roof ditch molding 34, a profiled end having tabs 40 is provided, as shown in FIG. 8A. Next, the final roof ditch molding 34 is stretch-bent in a stretch bender 98 to match the contour of the vehicle roof 12, and the notch tab 40 at the end 36 of the final roof ditch molding 34 is shaped to close the end of the molding and give the vehicle 10 a highly finished appearance. In one example, the form 34 is placed in a stretch bender 98 and clamped in place. The molding 34 is then shaped to fit the contour of the roof 12. The tab 40 at the end 36 of the form 34 is then bent, for example, up to 90 degrees to provide the final formed end 44. The form 34 is then removed from the stretch bender 98.
Conventional attachment brackets, clamps and foam pieces (not shown) are still required and assembled to the molding. However, the need for a separate end cap and assembly is eliminated. Thus, the roof ditch molding 34 of the present subject matter provides a cleaner and more elegant appearance when compared to molding having an end cap. Further, bending the tab 40 to provide the final shaped end 44 results in significant cost savings.
Although specific component relationships are shown in the drawings of the present disclosure, the illustrations are not intended to limit the disclosure. In other words, the placement and orientation of the various components shown may vary within the scope of the present disclosure. In addition, the various figures accompanying this disclosure are not necessarily drawn to scale, and some features may be exaggerated or minimized to show certain details of particular components.
The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. Accordingly, the scope of legal protection given to this disclosure can only be determined by studying the following claims.
