Abstract
The present invention provides a mould method of cold press forming for pressing automotive composite girders at one step in the automotive industry and the use of girders for the same series of heavy automobiles. Double-layer longitudinal gingers of the same heavy-duty automobiles are pressed into formation according to the design requirements of products; the left double-layer longitudinal girders and the right double-layer longitudinal gingers are formed and combined by six pairs of press forming moulds, which is respectively divided into respective three procedures of the composite integration of the inner left gingers, the composite integration of the inner right gingers and the composite integration of the outer gingers. On the basis that an original upper mould base and an original lower mould base are not changed, the convex-concave mould and the spring spindle of the double-layer longitudinal gingers are modified at the corresponding change part, and thus, the module has multifunction. The mould of which the total weight is 73 tons, the length is 9 m and the height is 1.3 m, solves the one-step cold-press forming of the double-layer series of longitudinal gingers of the heavy-duty automobiles.
Description
The invention belongs to pressure-shaped mould tool mechanical field, be mainly used in cold-press moulding of auto industry crossbeam.
Product design requirement by West Germany Ben Ci motor corporation similar heavy-duty car variable cross-section bi-laminate curved longeron, be inner beam, outer beam respectively single-piece be formed with the compound one press forming of the 2mm magnitude of interference, realize left and right double-deck stringer forming and pressing with six pairs of pressure-shaped mould tools usually.So under the same conditions, production efficiency is low, it is big to take the production area, labor strength is big, and mould design, manufacturing are invested very big, and the cycle is long, longer to exploitation homologous series modified product trial-produce period, invest bigger, the longitudinal beam of present domestic truck generally by individual layer steel plate press forming or press forming the longeron internal layer add one again and strengthen gusset and weld, to improve the rigidity and the intensity of longeron.
The present invention is means with the mechanical technique for exploitation China heavy-duty car sets out, and the realization one module multiple usages is a purpose, solves cold-press moulding of double-deck serial longeron.
The present invention adopts two uneven in length (in 10000mm～6000mm) thickness differences (in the 20mm), and the low alloy steel plate 16mm that width does not wait is overlapping, is power with the hydraulic press, promotes cold-press moulding of pressure-shaped mould.73 tons of its mould gross weights, long 9 meters, wide 1.3 meters, high 1.1 meters, on, counterdie each minute three sections six compositions, every section joint all is to be cross-linked, flat key centering, to guarantee the mold integral good rigidly, stressed even, on, bottom plate, protruding, die all adopts the segmentation bolt to connect, die orifice material selection Tool Alloy steel, and heat treatment is HRC55～65, form accuracy and highly polished, design five push rods and three spring spindles in the impression, also designed five special-purpose push rods in the press, directly replaced the effect of retainer plate, the operational procedure that had both met hydraulic press has satisfied the serviceability of pressure-shaped mould again.
To be further elaborated invention in conjunction with the accompanying drawings:
Fig. 1, right double-deck longeron front view (Zuo Liang and right beam symmetry)
Fig. 2, right double-deck longeron vertical view
Fig. 3, right double-deck longeron sectional drawing
Fig. 4, double-deck serial longeron pressure-shaped mould sectional drawing
Fig. 5, double-deck serial longeron pressure-shaped mould assembly front view
Fig. 6, double-deck serial longeron lower mould assembly vertical view
According to Fig. 4, Fig. 5, Fig. 6 illustrates mould structure and the operation principle that proposes according to the present invention.
Punch (4) is assemblied on the Connection Block (3) by bolt and flat key (14), refill and fit on the upper bolster (2), three leads (5) are respectively assembled in the upper bolster both sides, die plate insert (6) and backing plate (7) use bolts assemblies on die socket (8), five push rods (11) and three spring spindles (16) are housed in the die thorax, five special-purpose push rods (10) have been housed on the hydraulic press workbench (9), assembled on each four activity orientation piece (12) and the left side in both sides, plane on the die socket two locating pieces (15) have been housed, and with six leads (5) control die clearance, when compacting workpiece stock is sent in the die socket locating piece, hydraulic press moved cross beam (1) moves downward, with its shaping, starting (1), special-purpose push rod (10) in the hydraulic press workbench rises, jack-up (11) workpiece ejects, and takes out workpiece again.
The present invention takes the modular construction design, has realized one module multiple usages, and its effect is as follows:
1, the double-deck serial longeron reliable in quality of the heavy-duty car suppressed of the present invention meets the product technology requirement fully.
2, this mould structure slightly adjusts the double-deck longeron that can suppress the homologous series different size.
3, dismounting, convenient transportation, handling safety is reliable, and it is few to take plant area.
4,, be example with double-deck longeron, if make a casing pressure shape mould again according to the product technology requirement, need 500,000 yuan by factory's cost accounting, other factory's cooperation needs 2,000,000 yuan, and the cycle is more than 2 years, now utilize double-deck longeron mould design improvement, only used 30,000 yuan, three months manufacturing cycles.
5, saved a large amount of compacting expenses, six procedure press formings, the existing two procedures that only needs can be shaped.
6, for country has saved a large amount of foreign exchanges, import one bogie frame needs 8000 marks, by producing 2000 per year, can save foreign exchange 1,600 ten thousand marks every year.
7, use the double-deck longeron of heavy-duty car of this method compacting, its performance is better than the longeron of domestic automobile of the same type.
8, the present invention has been used for weapons portion iron-clad horses truck and distortion car (having developed 12 kind vehicles).
9, external relevant document and retrieval find no this report.
Claims (2)
1, a kind of cold stamping die is made up of upper die and lower die, push rod, supporting plate, bolt, and each constitutes by three sections to it is characterized in that upper and lower mould, and every section joint system is cross-linked, and by flat key centering; Upper and lower mould, supporting plate, protruding, die all adopt the segmentation bolt to link to each other with base, and five push rods, three spring spindles are housed in the impression.
