The specific embodiment
As shown in Figure 1, 2, the invention provides a kind of ultra-high strength steel hot stamping mould supporting mechanism, described ultra-high strength steel hot stamping mould supporting mechanism comprises: die ontology 1, hold up that piece 2, guide pin bushing 3, material returned screw component 4, spring 5, cylinder 6, patrix insert 7, upper mould body 8, product 9; Described picking-up piece 2, with water channel 21, by being incorporated into the water pipe outside die ontology 1, provides circulating water on it.Holding up piece 2 materials is that material is the special hot die steel of drop stamping.In punching course, hold up piece 2 and participate in product shaping; Punching press completes pressurize and quenches the stage, holds up 7 actings in conjunction of inserting of piece 2 and patrix, product 9 is realized under certain pressure to quenching.
Described guide pin bushing 3, is installed on die ontology 1.On this guide pin bushing wall, with oil groove, can in guiding, realize self-lubricate function.
Described material returned screw component 4, is made up of screw 41, sleeve 42, packing ring 43 3 parts.Screw 41 is oppositely installed on and holds up on piece 2, and sleeve 42 tops are embedded in and hold up the interior 20mm of piece 2, and mobile jib part is joined with guide pin bushing 3 is sliding, by the fixation of packing ring 43, has controlled the Z-direction motion of sleeve 42, thereby has realized the stable guide function that holds up piece 2.Be jacked to after design operational height when holding up piece 2, packing ring 43 acts on die ontology 1, controls the stroke that holds up piece 2.
Described spring 5, is installed between die ontology 1 and packing ring 4C.Original state, spring 5 does not stress for free state; After picking-up piece 2 is upwards held up, spring 5 stress deformations, in the time that cylinder force 6 power disappear, spring 5 provides a reverse power, promotes material returned screw component and drives picking-up piece 2 to withdraw downwards.
Described cylinder 6, is installed on die ontology 1, and top is fixing with picking-up piece 2.On cylinder, with two gas circuit mouths, there is gas circuit pipe to be connected on the source of the gas outside die ontology 1, by controlling air pressure change, thereby realize picking-up piece jack-up and withdraw.
Described patrix inserts 7, is installed on mould body 8, and patrix is inserted on 7 with water channel 71, by being incorporated into the water pipe outside die ontology 8, provides circulating water.Patrix 7 materials of inserting are the special hot die steel of drop stamping.
For realizing the reasonable stress of supporting mechanism, reduce the mechanism-trouble causing because of mechanism wear, unbalance stress, described screw 41 diameter 16-20mm; Preferably 18mm; Described sleeve 42 length are 200 ± 20mm, preferably 200mm; Be 18-22mm, preferably 20mm at the fitting depth holding up in piece 2; Described guide pin bushing 3 length are 28-32mm, preferably 30mm.
More specific description working motion process of the present invention below.
Figure 1 shows that initial product puts into state.Holding up piece 2 original states is positioned on lower mould body 1.3 guiding left and right of material returned screw component 4 and guide pillar.Spring 5 does not stress without distortion in free state.Product is 900---and in the heating furnace of 950 ℃, heat after 5 minutes, be placed on and hold up on piece 2.
Patrix 8 drives patrix to insert and 7 moves downward, and inserts and 7 touches after product 9 when patrix, inserts under 7 actings in conjunction holding up piece 2 and patrix, and plastic deformation occurs product 9.
Figure 2 shows that punching press completes pressurize as-quenched.After product 9 plastic deformations complete, and hold up 7 laminatings completely of inserting of piece 2, patrix.Hold up piece 2, patrix and insert in the situation of 7 assurance certain pressures, owing to holding up piece 2, patrix inserts 7 all with cooling water channel, can take away fast heat, product 9 in mould by quench cooled.
Figure 3 shows that product holds up state diagram, after pressurize has been quenched, upper mould body 8 drives patrix to insert and 7 moves upward after certain altitude and stop, cylinder 6 starts inflation, promoting to hold up piece 2 moves upward, reach after design height, the packing ring 43 on material returned screw component 4 contacts with lower mould body 1, and restriction holds up piece and continues motion.Manipulator stretches in mould, and product 9 is taken out.
After product 9 takes out, stop after inflation in cylinder 6, because spring 5 is compressed, spring applies downward power by material returned screw component 4 to holding up piece, thereby drives picking-up piece to move downward, and revert to original state position shown in figure mono-.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
