Definitions
- the invention relates to a process for the aftertreatment of one-piece stainless steel moldings which have been produced from deep-drawable stainless steel blanks or blanks by deep drawing, punching, rolling and shaping.
- This object is achieved according to the invention in that the finished molded articles are treated immediately after production in a drum equipped with hard granulate particles and set in rotary movements.
- Ceramic particles which have a particle size in diameter which is smaller than twice the radius of rounded convex and / or concave surface regions of the moldings are preferably used as granulate particles. It should also be noted that the deep-drawing, stamping, rolling and shaping processes are carried out in immediately successive process steps.
- An aftertreatment has proven to be particularly advantageous in which the aftertreatment time and / or the speed of the drum are selected as a function of the material thickness and / or the size of the surface of the moldings.
- the material thickness for the panels for motor vehicle exhaust pipes produced as stainless steel moldings is advantageously chosen to be 1 to 1.2 mm.
- the method according to the invention can advantageously be applied to a one-piece stainless steel blank 10 according to FIG. 1, which is produced from a stainless steel blank and is used as a diaphragm for the end of a motor vehicle exhaust pipe.
- One end face 1 2 is chamfered, punched out with a hole 14 and provided with a rolled-up edge 1 5 around hole 1 4.
- the jacket 11 of the panel is drawn in several deep-drawing steps and cut off perpendicularly to the longitudinal axis in the region of the other end face 13, as the reference number 17 shows.
- the end section 1 6 is reduced in diameter by upsetting to return movements of the jacket
- Fig. 2 shows the view in the jacket 1 1 from the front side 1 7 and Fig. 3 shows the rolled edge 1 5 in the region of the front side 1 2 on an enlarged scale.
