Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Shown in Fig. 1-Fig. 5, in Fig. 4, the dotted line at each drift place is to six drifts be distinguished, and convenient observation understands use.The progressive die of the cylinder cover hood seal gasket metallic framework of a kind of formed automobile engine of the present invention, comprises mould bases, charging guide holder, the grading processing assembly of six steps; Described mould bases comprises die shank 1, top mold frame 2, upper padding plate 3, die 15, lower bolster 16 and lower mold holder 17 from top to bottom, and die 15 is fixed on lower bolster 16; To lead with guide pillar 20 through ball bearing guide bushing 19 between top mold frame 2 with lower mold holder 17 and coordinate.Top mold frame 2 connects punch press top by die shank 1; Lower mold holder 17 is provided with mould pin 18 and both are arranged on work bench of punch press together.
Guide holder is arranged on mould bases front end, and the grading processing assembly of six steps is arranged between top mold frame 2 and lower mold holder 17; The grading processing assembly of six steps comprises upper punch fixed head 4, guide pin backing plate 5, guide pin 11, holding pad 6, guide pin backing plate 5 and holding pad 6 are suspended on below upper punch fixed head 4 through screw from top to bottom, helical spring 27 is housed between guide pin backing plate 5 and upper punch fixed head 4, guide pin 11 is through on holding pad 6 from top to bottom, guide pin backing plate 5 covers on holding pad 6 and guide pin 11, prevents guide pin 11 from dropping out.
The grading processing assembly of six steps also comprises and is arranged on successively from front to back on upper punch fixed head 4 and flattens binder drift 12, stepping six separate punches 13 drift 10, the adjacent vulcanization member of stepping five through the stepping one installing hole drift 7 of guide pin backing plate 5 and holding pad 6, Stepping positioning hole drift 8, stepping trisulfides forming punching head 9, stepping four vulcanization member simultaneously, and described die 15 is provided with the forming cavity corresponding with above-mentioned six drifts.
Have a lot of hollow out to design in the middle of metallic framework 14 after shaping, between metal support body, bonding strength is lower, and easily deform distortion.The grading assembly of six step of the present invention is when molding sulfuration part 14.1, adopt step 3 and progressive being excised by material unnecessary for vulcanization member 14.1 surrounding of step 5 two steps, specially binder drift 12 between the adjacent vulcanization member of stepping five designed, after being placed on stepping four vulcanization member flattening drift 10, the advantage done like this works as step 4, when flattening vulcanization member 14.1, improve the bonding strength of metallic framework 14 metal support body, prevent from flattening process process, causing whole metal firmware 14 to be out of shape.After flattening process completes, then by die-cut for material unnecessary for metallic framework 14 hollow part, avoid metallic framework 14 to be out of shape, mention product percent of pass.
Described charging guide holder comprises fixed guide reservation 24, guide runner 23, guiding pin 25, guide pad 22; Fixed guide reservation 24 is fixed on the front of lower mold holder 17, and guide runner 23 sliding fit is in the guide rail of fixed guide reservation 24, and guide pad 22 is connected with guide runner 23, and guiding pin 25 is arranged in guide pad 22.
