Embodiment Construction
[0016] see figure 1 , a processing method for processing an automobile steering arm in the present invention, comprising the following steps: 1) OP10-OP30 punching and trimming process: punching and trimming strips, punching out positioning process holes and product contours, and making adjacent The middle part between the two parts remains connected, and the rest is cut off to generate a stretchable strip; 2) OP40 pre-drawing process: one-time drawing, through two groups of activities arranged perpendicular to the feeding direction and moving in this direction Both ends of the part are simultaneously drawn by the convex and concave dies; 3) OP50 secondary drawing process: two sets of secondary drawing fixed dies arranged perpendicular to the feeding direction are used to simultaneously draw both ends of the part; 4) OP60 three-time drawing Process: through two sets of three-time drawing fixed dies arranged perpendicular to the feeding direction, both ends of the part are simu...

The invention discloses a movable male die and female die progressive die and method for producing an automobile steering arm. The method comprises the steps that (1) strip materials are punched and trimmed, and it is ensured that the middle portions between every two adjacent parts are connected all the time and the rest parts are cut off; (2) one-time drawing is carried out, wherein two ends ofthe parts are drawn simultaneously through two groups of movable dies capable of moving in the feeding direction; (3) the two ends of the parts are drawn simultaneously through two groups of secondarydrawing fixing dies; (4) the two ends of the part are drawn simultaneously through two groups of tertiary drawing fixing dies; (5) the two ends of the part are drawn simultaneously through two groupsof quaternary drawing fixing dies; (6) the parts are shaped simultaneously through two groups of shaping and fixing dies; and (7) blanking is carried out. When the movable male die and female die progressive die and the method are adopted to carry out drawing, a male die and a female die can move along with the flowing of the materials, and therefore the phenomenon that the parts are drawn and cracked due to the fact that the flowing of the materials is blocked by the two ends of the fixing drawing male die and female die is avoided. The structure can be suitable for progressive die production, single-step die production can be replaced by progressive die production, and the production efficiency is high. The movable male die and female die progressive die is a double-head movable male die and female die drawing progressive die of the automobile steering arm.
Description
technical field [0001] The invention relates to a progressive die and method of a movable convex and concave die for processing an automobile steering arm. Background technique [0002] Both ends of the steering arm of the car need to be drawn. When both ends are drawn at the same time, the fluidity of the material is not good, which is easy to cause material cracking. The normal process is to draw one end of the product first, then turn around and draw the other end, and finally draw both ends at the same time. Shaping to ensure the center distance of the product. This can only be produced with a single-process mold, and the efficiency is too low. Contents of the invention [0003] The purpose of the present invention is to set up a kind of movable convex and concave die progressive die and method for processing the steering arm of the automobile for the steering arm that needs to be drawn at the same time at both ends to overcome the material flow. Drawing cracking can...
