Abstract
Description
- This application claims priority from U.S. Provisional Patent Application No. 60/589,111 filed on Jul. 19, 2004, which is hereby incorporated by reference.
- The present invention is generally related to exhaust tubes, and more particularly to exhaust tubes having a draw-form formed therein.
- Many tubular structures designed to have components connected thereto. In such a case, many tubular structures utilize flat portions formed along the surface of the tubular structure for mounting components thereto. While such flat portions assist in mounting components to tubes, these flat portions can often be deformed during secondary forming operations or construction of the finished product. The deformation of such flat portions can prevent the connection of the required component and require additional forming operations to correct such deformations.
- The field of art has attempted to minimize the deformation to the flat portions caused by secondary operations by providing circular draw-forms having a flat portion therein (as shown in FIG. A). The circular draw-forms are stamped into the tubular surface so as to provide a flat portion upon which a component may be mounted. As such, the wall of the circular indentations is supposed to protect the flat portion from deforming during secondary forming or construction operations.
- One particular industry where tubular structures require such flat portions is the automotive industry and particularly the exhaust tube industry. For example, tubular catalytic converter canisters comprise tubular structures having draw-forms stamped therein so as to provide a flat portion where a HEGO boss (Heated Exhaust Gas Oxygen) can be welded for placement of the HEGO sensor. This sensor is used by the engine management system to monitor mixture strength in the exhaust gases. In construction of such canisters, a circular draw-form indentation is typically stamped into the tubular structure so as to provide a flat surface for the HEGO boss. Converter bricks are then stuffed inside the tube and the entire assembly is swaged, or reduced to a smaller diameter, in a secondary operation. The forming forces during swaging tend to deform the flat portion and the attached HEGO boss under the current forming methods (as shown in
FIGS. 1 and 2 ). - It has been observed that circular shaped draw-forms tend to deform during subsequent forming operations. Deformation of the draw-forms and their flat portions can inhibit the connection of the HEGO sensor and make the tube worthless for its intended purpose. Such deformation of the draw-form and flat portion must be repaired or reformed in subsequent operations to permit the proper connection of the HEGO sensor. Such corrective action can be time consuming and costly. Therefore, there is a need in the art to prevent the current occurrence of deformation found in circular draw-forms during subsequent forming operations.
- Therefore, there is a need in the art to provide a draw-form and a method for producing a draw-form in a tubular structure that either does not deform, or minimally deforms, so as to maintain the required flat portion needed for the proper connection of components.
- Accordingly, the present invention provides a tubular member having an outer wall, and a draw-form formed in the outer wall. The draw-form comprises a substantially flat bottom portion, a plurality of walls extending upwardly from the bottom portion and attached to the outer wall, and wherein the walls are configured in a polygonal orientation.
- In an alternative embodiment, the present invention provides an exhaust tube that comprises a tube having an outer wall defining an interior exhaust passage, a draw-form formed in the outer wall. The draw-form comprises a substantially flat bottom portion, a plurality of walls extending upwardly from the bottom portion and integrally attached to the outer wall, and wherein the walls are configured in a polygonal orientation to substantially prevent deformation of the draw-form during subsequent forming operations.
- In yet another embodiment, the present invention provides a method of manufacturing a draw-form. The method comprises placing a tubular member having an outer wall in a fixture, forming a substantially flat bottom portion in the outer wall of the tube, forming a plurality of walls extending upwardly from the bottom portion and attached to the outer wall, wherein the walls are configured in a polygonal orientation to maintain the bottom portion substantially free from deformation during subsequent forming operations.
- Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
- Objects and advantages together with the operation of the invention may be better understood by reference to the following detailed description taken in connection with the following illustrations, wherein:
- FIG. A is a top view of a tubular member having a previously known circular draw-form therein;
-
FIG. 1 is a top view of a tubular member having a previously known circular draw-form and HEGO boss showing deformation thereof after a secondary forming operation; -
FIG. 2 is an interior view ofFIG. 1 ; -
FIG. 3 is a perspective view of a tubular member having a draw-form according to the present invention. -
FIG. 4 is an interior view ofFIG. 3 ; -
FIG. 5 is a close-up view of the draw-form shown inFIG. 3 ; -
FIG. 6 is a cross-sectional view and close-up thereof of a tubular member having a draw-form with a MIG welded HEGO boss connected thereto; and -
FIG. 7 is a cross-sectional view and close-up thereof of a tubular member having a draw-form with HEGO boss CD welded thereto, which is the most preferred embodiment of the present invention. - While the present invention is described with reference to the preferred embodiment, it should be clear that the present invention could be used with any tubular structure in any industry where tubular structures require flat connection portions. Therefore, the description of the preferred embodiment herein in illustrative of the present invention and should not limit the scope of the invention.
- With reference to
FIGS. 3-5 , a draw-form 10 is formed in a tubular member ortube 12. Thetube 12 can be made from any material that permits formation of the draw-form 10, and is preferably composed of metal material. Thetube 12 includes anouter wall 11 that defines aninterior exhaust passage 13. The draw-form 10 comprises a substantiallyflat bottom portion 14 having anaperture 16 extending therethrough and bounded bywalls 18 configured in a polygonal orientation. Thewalls 18 may be substantially parallel to saidbottom portion 14, but may also be at a non-right angle thereto, such as an acute or obtuse angle. Additionally, thewalls 18 are attached to theouter wall 11 of thetube 12. They may be attached integrally. Additionally, thewalls 18 may be attached to thebottom portion 14 either integrally or non-integrally. To non-integrally attach thebottom portion 14 to thewalls 18, thebottom portion 14 is welded in place. Otherwise, if thewalls 18 are integrally formed with thebottom portion 14, the two are created during a forming operation such as stamping. - Preferably, the
walls 18 are configured to form a rectangular or square configuration, however, other polygonal orientations may be used. The straight-line walls 18, which may have rounded corners, act as strengthening ridges that prevent the deformation of the draw-form 10 during subsequent forming operations, such as swaging, so as to maintain theflat portion 14 substantially free from deformation. As such, the polygonal draw-form 10 restricts the movement of tubing material in the area where the draw-form 10 exists and maintains theflat portion 14 in generally its stamped configuration. In other words, the polygonal draw-form 10 prevents large displacements in the formed area during a secondary post draw-form operation. - In the method of manufacture, the
tube 12 is placed with a draw-form press (not shown). A properly configured polygonal male punch is used in conjunction with a corresponding polygonal female die to make the desired polygonal draw-form 10 at the desired draw depth in thetube 12. As indicated above, the draw-form 10 can be any polygonal figure, but preferably the draw-form is either rectangular or square. - Once the draw-
form 10 has been formed in thetube 12, the HEGO boss can be mounted to the draw-form 10. As shown inFIG. 6 , the traditional method of mounting aHEGO boss 20 to the draw-form 10 is by MIG welding, although any welding process can be utilized. TheHEGO boss 20 is inserted within theaperture 16 and connected bywelds 22 therein. As shown inFIG. 7 , the preferred embodiment, theHEGO boss 20 is CD welded (capacitive discharge) to the interior of the draw-form 10. InFIG. 7 , theHEGO boss 20 includesprotrusions 30 thereon that assist in attaching it to the draw-form 10. Theprotrusions 30 can be used to temporarily attach theHEGO boss 20 to thebottom portion 14 of the draw-from 10 until it is welded in place. Alternatively, theprotrusions 30 can be used to attach theHEGO boss 20 directly to thebottom portion 14. Additionally, theHEGO boss 20 may be attached to the underside of thebottom portion 14 of the draw-form 10, as shown inFIG. 7 , or it may be attached to the top side of thebottom portion 14. - The present polygonal draw-form displays strength characteristics superior to the prior used circular draw-forms during secondary forming operations. As opposed to the circular draw-forms, the angular orientation of the straight-lined
walls 18 withstands and better distributes the forces acting thereon during the secondary forming operation. - The invention has been described above and, obviously, modifications and alternations will occur to others upon a reading and understanding of this specification. The claims as follows are intended to include all modifications and alterations insofar as they come within the scope of the claims or the equivalent thereof.
