Claims
- 1. Apparatus for producing a linkage between an exhaust pipe and a hollow cylindrical air/fuel ratio detector holder with an opening for receiving an air/fuel ratio detector in the holder, comprising means for providing a desired finished shape of the exhaust pipe through internal high-pressure on a buckling portion of the exhaust pipe so as to have an inverted contact contour shape complimentary to a convex casing surface of the detector holder, said means including:an internal high-pressure tool divided into an upper die and a lower die for forming a surface by inserting a blank pipe into the desired finished shape of the exhaust pipe, and a shaping device integrated into the tool with a contour facing the pipe corresponding to a contact contour of the casing surface of the holder at a location of intended contact surface at the exhaust pipe.
- 2. Apparatus according to claim 1, wherein the shaping device is constituted by a buckling portion of the surface of the tool.
- 3. Apparatus according to claim 1, wherein the shaping device is formed by a stamping die which is adjustably guidable in a guide bore arranged in the tool and leads into the surface, whereby the contour of the stamping die, having a face movable into the engraving, is shaped correspondingly to the contact contour of the casing surface of the holder.
- 4. Apparatus according to claim 1, wherein a punching die is integrated into the remodeling tool for producing the opening in the finished exhaust pipe.
- 5. Apparatus according to claim 4, wherein the shaping device has a bore within which its punching die is adjustably held.
