Detailed description of the invention
embodiment 1
The present embodiment provides a kind of cold stamping negative angle a bending and molding device, structure as depicted in figs. 1 and 2, comprise cope match-plate pattern 1 and lower bolster 2, be connected by lead between cope match-plate pattern and lower bolster, lead comprises guide pillar 3 and guide pin bushing 4, guide pillar is arranged on lower bolster, and guide pin bushing is in the lower end at cope match-plate pattern; Cope match-plate pattern bottom is provided with mold mounting plate 5, and upper mold mounting plate is provided with punch 6 and oblique contract drive block 7, and oblique contract drive block lower end is provided with inclined-plane, and the height of punch is longer than the height of oblique contract drive block; The upper surface of lower bolster is installed with lower mold mounting plate 8, the both sides of the punch projected position on lower mold mounting plate are respectively equipped with left side folded block 9 and oblique contract sliding block 10, the upper end of left side folded block and oblique contract sliding block is provided with the location-plate 11 of locating steel plate to be punched, left side folded block and oblique contract sliding block both sides are provided with interior de-guide plate 15, make the interior de-guide plate of left side folded block, tiltedly contract sliding block and both sides form interior taking off and strike out die cavity, in this forming cavity, be provided with material returned spring 12; Oblique contract sliding block de-strike out the end face that die cavity contacts with interior and is provided with lean-in inclined-plane, oblique contract sliding block 10 both sides are provided with slider guide plate, the other end of oblique contract sliding block is connected with oblique contract limited block 13 by back-moving spring, and oblique contract limited block and oblique contract locating piece 14 are fixedly linked; Oblique contract sliding block contacts one end with oblique contract limited block and is provided with driving inclined-plane, drives inclined-plane and inclined-plane, oblique contract drive block lower end to fit and drives, and promotes oblique contract sliding block move back and forth between left side folded block and oblique contract limited block by oblique contract drive block.
A process for stamping for a cold stamping negative angle bending and molding device, comprises the following steps:
(1) steel plate to be punched is placed in the location-plate of the upper end of left side folded block and oblique contract sliding block;
(2) start the hydraulic means on cope match-plate pattern, cope match-plate pattern is moved down, when upper and lower mould has just started to contact, the downward punching press of punch steel plate to be punched, oblique contract drive block does not touch oblique contract sliding block, cannot produce driving force to sliding block, now sliding block is close to oblique contract limited block under the effect of back-moving spring, and its oblique contract sliding block is equivalent to the effect of right side folded block;
(3) cope match-plate pattern continues to move downward, and completes the preliminary bending process treating stamping steel plate, and now tiltedly contract drive block starts to contact oblique contract sliding block;
