By adopting the above technical scheme, this vehicle seats lock pawl processing technology step is through sawing sheet, punching, correcting, and raising is cold It squeezes, fine and trimming, realizes the high-precision of lock pawl processing, it is easily molded, it improves automotive seat and is latched in safety and can By the problem of property deficiency, the stability of vehicle seats has been ensured.

The further setting of the present invention: a length of 29mm of the size of the machining area, width 22mm, a height of 4mm.

By adopting the above technical scheme, a length of 29mm, width 22mm, a height of 4mm machining area are sized to most preferably.

The further setting of the present invention: cold extrusion includes multiple cold extrusion, and the cold extrusion number is 10 times or more.

By adopting the above technical scheme, plate can make plate to be processed have high-precision because of material limitation through multiple cold extrusion, Size in Cold Extrusion Process is gradually reduced, and preliminary cold extrusion diameter is 5mm, and secondary cold extrusion is having a size of 4mm, and centre is through multiple After cold extrusion, final cold extrusion diameter is 2.5mm, and size is gradually reduced by initial 1mm space reductions with 0.5mm, is improved whole Body machining accuracy.

The further setting of the present invention: the groove diameter is 5.2mm.

By adopting the above technical scheme, the groove diameter of 5.2mm is set as best.

The further setting of the present invention: the ejection pillar height degree is having a size of 7mm.

By adopting the above technical scheme, the height dimension that 7mm ejects column is set as best.

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 Discharging forms ejection column 2, and the angle between ejection 2 side wall of column and machining area is that arc angle 3 is arranged；Step 5: to adding Work area domain side carries out tooth form fine, and the structure of the tooth form fine 4 includes U-lag 11 and step, and the step includes first Step 12, second step 13 and third step 14, the first step 12, second step 13 and third step 14 are successively to downward Stretch, structure one end of the tooth form fine 4 is bent upwards through U-lag 11 vertically downward along machining area, then through first step 12, It second step 13 and extends downwardly for third step 14 times；Step 6: to the waste material generated after raising, cold extrusion and tooth form fine into Row trimming processing.

This vehicle seats lock pawl processing technology step is realized through sawing sheet, punching, correcting, raising, cold-extruded, fine and trimming The high-precision of lock pawl processing, it is easily molded, improve the problem that automotive seat is latched in safety and reliability deficiency, guarantee The stability of vehicle seats.
