The specific embodiment
Embodiment 1: the SABS support is as example in the processing daily output C16A of our company torsion beam:
Daily output C16A SABS rack forming mould is to take " increase technique and stay long and fabrication hole " to realize the locate mode of complex-curved upper two pin-and-holes location, its positioning datum is located at the peak of loose plug, can avoid well blank on complicated, irregular curved surface during moulding because play causes the phenomenons such as product is monolateral, SABS rack forming mould mould structure is shown in Fig. 1-4:
Upper die structure relation is: punch 5, upper padding plate 4 are installed on the cope match-plate pattern 3 by order illustrated by bolt, and one reinstates holding pin and fixes; Guide pin bushing 2 interference fit are squeezed in the dowel hole that is fixed on cope match-plate pattern 3 correspondences.
The lower die structure relation is: die block 9, lower bolster 14 are bolted on lower bolster 15, and fixing together with steady pin; Die plate insert 8 interference fit are squeezed into the solid shaped cavity that forms in the lock chamber of die block 9, and are connected with lower bolster 14 by bolt; In the locating hole of alignment pin 6 burying forming top boards 10, and the spring 12 of packing into, be bolted together with cushion block 11 again, form the comprehensive movable component that integrates location, moulding, liftout, after assembly fixes, guarantee that alignment pin 6 exceeds moulding top board 10 upper surface 3.0mm, can be movable downwards when alignment pin 6 is subjected to force compresses, movable component is placed in the solid shaped cavity of the fixation kit that is formed by die plate insert 8 and die block 9 by matched in clearance; Push rod 13 is placed on cushion block 11 belows, and passes lower bolster 14 and lower bolster 15, passes straight through to the lathe plunger tip; Guide pillar 1 interference fit is squeezed into and is fixed on the lower bolster 15.When assemble the upper and lower part of above-mentioned mould, need to guarantee that punch 5 left and right two salient points are at same level height (such as Fig. 1).Punch 5 is controlled at except material thickness in the 0.1-0.15mm scope with the gap, composition surface of die plate insert 8.Moulding top board 10 and cushion block 11 assemblies can be in the solid shaped cavity that counterdie forms easy on and off movable, and when push rod 13 pushed up to peak, moulding top board 10 was higher than the upper surface of die plate insert 8.
Monolateral gap between fixation kit and the movable component is 0.18-0.22mm; The forming surface gap of the forming surface of punch 5 and die plate insert 8 is 2.60-2.70mm, namely is controlled at except material thickness in the 0.10-0.20mm scope.
Moulding process is as follows as shown in Figure 6:
(1), blanking: according to material 08, thickness 2.5mm and each dimensional requirement of moulding of SABS support in the Zhengzhou daily output C16A torsion beam, analysis and calculation goes out Workpiece shaping needs billet size, again according to the stock layout layout of blanking operation, determine the scrap (bridge) surplus, draw at last the product blank size.
(2), blanking: the process of determining the front road of Workpiece shaping operation concerned process steps is blanking size.Stay long size (20 * 48) to carry out the plate cae analysis by forming shape and technique, tentatively obtain the product development size, then finally determine the development size by on-the-spot actual tests.
(3), punching: the location needs according to daily output C16A SABS rack forming, stay long centre position to go out the hole of 2 φ 8.6+0.10 0 with perforating die in technique, be convenient to make positioning datum in molding procedure.
(4), moulding: at first, design shape, size and the pressing direction of moulding punch and matrix.Daily output C16A SABS rack forming punch adopts global shape, and except forming surface, other are regular cuboid, and the moulding position draws according to shape of product.According to forming height, angle, technique is stayed long and the locate mode requirement, and circular arc R 7 positions are made as the peak of molding concave die, and moulding angle reasonable in design, and left and right two salient points that punch contacts product when guaranteeing compacting contact product (as shown in Figure 1) simultaneously.Molding concave die is processed into profile according to shape of product, and each face is got suitable fillet to make things convenient for Material Flow according to forming direction.Then determine location and the pushing method of making, because of moulding location and head part needs, mould the latter half is designed a movable component, for this reason, molding concave die is split along circular arc tangential line, part interference is fixed in the die block (such as die plate insert 8), another part cooperates push rod easy on and off movable (such as moulding top board 10) in the solid shaped cavity of counterdie, hole site according to product on the moulding top board processes dowel hole and spring eye, and be connected with cushion block, location, moulding, liftout effect are played in combination.At last, determine processing technology and the assembly technical requirement of punch and matrix.Punch and matrix divides mould to draw according to product 3D shaping, and is come by the digital control processing of machining center integral body, guarantees that shape is identical, and the process line cuts die is divided into two (die plate insert, moulding top board) again.After the assembling, the gap of punch and die plate insert forming surface guarantees to be 2.60mm, can be up and down in the moulding top board during alignment pin pressurized, and the monolateral gap in moulding top plate member and the fractal chamber of mould Lower Half is 0.20mm, and when push rod pushed up to peak, the moulding top board was higher than the die plate insert upper surface.
Before the product compacting, push rod with the moulding Roof to peak, then the product that punching is good is put into two alignment pins and is located, punch is descending with lathe, about two salient points contact simultaneously product and continue product is suppressed complete moulding, punch presses down the disengaging product with alignment pin, after moulding is finished, patrix is up with the lathe slide block, and push rod ejects moulding top board and product, can take out product.
(5), cut off (technique is stayed length): according to daily output C16A SABS support product figure profile, will stay long (20 * 48) excision because the moulding location needs the interim technique that increases.
(6) rush pilot hole: welding position and reference for assembling according to daily output C16A SABS support product diagram technology requires go out two pilot hole 2-φ 8 with the perforating die punching out.
Such SABS support blanking, rush the processing and forming that just can be directly used in mould after the fabrication hole operation.The 1st step: will produce C16A SABS rack forming mould daily and be installed on the YB32-100 hydraulic press; The 2nd step: start hydraulic press, taking blame for others with lathe ejects push rod 13 and moulding top plate member, and ejection height is higher than die plate insert 8 upper surfaces; The 3rd step: will rush daily output C16A SABS stentplacement after the fabrication hole operation on the detent mechanism alignment pin 7 of mould, moulding top board 10; The 4th step: operation hydraulic press top shoe is descending, and punch 5 left and right two salient points contact at first simultaneously daily output C16A SABS support and proceed compacting, and are on earth to be pressed, the complete moulding of product; The 5th step: the hydraulic press top shoe is up, and the upper part of driven mold breaks away from return, and taking blame for others under the operation lathe ejects push rod 13 and moulding top plate member, and product ejects with the moulding top plate member, and can take out the product that ejects this moment; The 6th step: repeating step 2 is to the operation of step 5.
