Definitions
- the invention relates to a method for producing a cover which can be placed on the end of a motor vehicle exhaust pipe and which is made from deep-drawable stainless steel, and to a cover produced by the method.
- Such screens serve as a decorative piece on the end of the exhaust pipe protruding from the rear of a motor vehicle. For this reason, it depends crucially on the non-rusting raw material stainless steel and on the appearance of the surface of the panel.
- a round plate (10) is produced from stainless steel sheet
- a pot-like cup (10.1; 10.2; 10.3; 10.4) with a bottom (11.4) inclined with respect to the longitudinal axis (25) with a step-wise decreasing diameter (D1, D2, D3, D4) and a gradually increasing jacket length (L1, L2, L3, L4) pulled,
- the jacket (12.4) is cut perpendicular to the longitudinal axis (25) of the cup (10.4) to the required length (Lo) and a condensate (16) and / or a fastening hole is introduced into the jacket (12.5),
- the edge (14) of the base (11.5) is bent parallel to the longitudinal axis (25) and then rolled into a cup (10.6) to form a circular arc (17) and
- the transition from the inclined floor to the casing of the various deep-drawing steps is always rounded off, so that no damage occurs in the transition area from the floor to the casing of the drawn cup.
- the base is inclined to the jacket of the various deep-drawing steps over a diameter of approximately 70 ° or 110 ° to the longitudinal axis.
- one embodiment provides that the jacket is cut to the required length and the condensate drain opening is inserted and / or mounting hole can be performed together. These process steps can be carried out together since they take place in the same processing direction. If it is provided that the hole in the bottom is cut before the circular-arc-shaped end is rolled in, then the rolled-in end of the beveled end face of the cup becomes uniform.
- a diaphragm produced by the method is characterized in that it is designed in one piece as a sleeve, one end face inclined to the longitudinal axis being provided with an arc-rolled end and the other end face perpendicular to the longitudinal axis having a diameter in the adjoining end section which is smaller than the diameter of the rest of the jacket.
- the rolled-in end stiffens and avoids sharp edges, while the retracted end section stabilizes the drawn panel and prevents undesirable material restoration due to tension in the material.
- the jacket of the sleeve-shaped cover is provided with an opening and / or bore, which can be used as a condensate drain or for connecting the cover to the exhaust pipe.
- Fig. 1 4 the view from the front with the retracted
- Fig. 1 5 in an enlarged partial view the rolled-up end of the beveled side of the finished panel.
- the blank 10 shown in side view in FIG. 1 is made of deep-drawn stainless steel sheet with a diameter D1 of z. B. 1 90 mm and a thickness do of, for example, 1 to 1, 2 mm, preferably cut.
- the cup 1 0.2 with a smaller diameter D2 96.95 mm, but with a greater length L2 of the casing 1 2.2, is drawn, so that the cup 1 0.1 according to FIG. 1 has become cup 1 0.2, as shown in FIG. 3 shows.
- the lengths L1 to L4 result automatically, since the output round 1 0 is defined.
- the slider is cut with a cutting punch 20 and a central hole 1 3 is punched into the base 1 1 .5 with the punch 30 so that an annular edge 1 4 remains around the hole 1 3 ,
- FIG. 8 shows a cutting tool 40 and a punching tool 50, with which the jacket 1 2.5 of the cup 10.5 according to FIG. 7 has the length Lo to the required dimension is shortened, the end face 1 5 obtained being directed perpendicular to the longitudinal axis 25 of the cup 1 0.6.
- a breakthrough 1 6 and / or a hole is punched into the jacket 1 2.5, it being possible for the jacket 1 2.6 to be cut off and the diameter 1 6 and / or the hole to be punched simultaneously, since the two directions of operation of the processes are the same.
- the bore 1 3.1 can be cut to position the edge 14.1 uniformly around the jacket 1 2.5 of the cup 10.6.
- a region of the edge 14.1 adjacent to the hole 1 3.1 is first bent parallel to the longitudinal axis 25 of the cup 1 0.6 and then subsequently shaped in a circular arc with tools 60 and 65.
- the tools 60 and 65 are adapted to one another in a semicircle in the facing corner regions, as shown in FIGS. 10 and 11.
- Fig. 1 2 shows, the finished end face 1 1 .5 of the cup is held with the tool 65 and a tool 70 pulls the end section 1 8 in the region of the cut end face 1 5 in such a way that the diameter of the diaphragm 10.7 is reduced in this area.
- the aperture 10.7 is supported in the receptacle 1 9 of the tool 70.
- the rolled-up end 1 7 in the region of the end face 1 1 .6 not only avoids sharp edges, but also serves in connection with the drawn-in end section 1 8 of the casing 1 2.5 to stabilize the deformed cover 10.7, so that the tensions arising from tensions in the material increase no uncontrollable material reset with impairment of the surface of the aperture 1 0.7.
- FIGS. 1 3 to 1 5 show a vertical section through the finished panel 1 0.7 with the rolled-in drain 1 7 on the inclined face 1 1 .6 with the hole 1 3.2 and the drawn-in end section 1 8 on the cut face 1 5.
- the cut leaves also recognize the wall thickness of the panel 10.7, which is obtained with a material of approximately 1 to 1.2 mm thick and can inevitably also be of different thicknesses, which is due to the various processing operations.
- Fig. 14 shows the view into the cavity formed by the panel 10.7 seen from the front side 15, which serves as a receptacle for the end of a motor vehicle exhaust pipe.
