The further setting of the present invention: the ejection column outer end is fillet setting.
By adopting the above technical scheme, stress can be evacuated stress along the normal direction of circular arc by round-corner transition, be unlikely to crack
Lead to waste product, while enhancing overall aesthetics.
The further setting of the present invention: the arc angular radius is 0.5mm.
By adopting the above technical scheme, the arc angle of 0.5mm radius setting is best.
Detailed description of the invention
Attached drawing 1 is specific embodiment of the invention overall structure Fig. 1；
Attached drawing 2 is specific embodiment of the invention overall structure Fig. 2.
Specific embodiment
A kind of vehicle seats lock pawl processing technology as shown in Fig. 1 to 2, comprising the following steps: step 1: plate is carried out
Sawing sheet forms machining area, and is punched out to form correcting region at the diagonal both ends of plate；Step 2: pass through the correcting region
It goes to fix plate progress correcting；Step 3: processing mold includes punch-pin and cavity plate, is carried out by processing mold to machining area
Raising, for machining area between cavity plate and punch-pin, the raising of the machining area is contacted through punch-pin is downwardly protrude to form groove 1
Expect with ejection；Step 4: cold extrusion is carried out in groove, groove contacts downwards top by punch-pin between cavity plate and punch-pin
