Description
Technical field
The utility model belongs to mould manufacturing field, is specifically related to a kind of recycle apparatus for tail gas of automotive vehicle flange loop forming mould.
Background technology
Research shows, the motor vehicle fuel energy discharged that burns only has about 1/3rd to be used effectively, and its complementary energy all scatters and disappears or is discharged in air, causes great energy waste, also causes adverse effect to environment.Therefore, the recirculation of automobile waste heat uses, and is conducive to the energy-saving and emission-reduction realizing automobile.
Flange ring is part in recycle apparatus for tail gas of automotive vehicle, and the traditional processing technology of this flange ring is that after lost-wax casting, machined is shaped.Defect intrinsic in casting technique is as wayward in pore, shrinkage porosite, crackle etc., in use gets rusty easily, and the mechanical property of foundry goods comparatively Plastic Forming part is low, affect the service life of part.Meanwhile, still need after casting to carry out follow-up machining processes, stock utilization is lower, and production efficiency is low.Therefore, research and development recycle apparatus for tail gas of automotive vehicle flange loop forming mould, make processing flange ring operation simple, properties of product are superior seems particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of recycle apparatus for tail gas of automotive vehicle flange loop forming mould.
The technical solution of the utility model is: a kind of recycle apparatus for tail gas of automotive vehicle flange loop forming mould, comprises necking in spindown and necking spinning forming two parts mould.
Described necking in spindown part mould comprises core and lower core; Described upper core and lower core band fluted, for fixing blank position, prevent pipe from the process of spinning roller feeding, radial deflection occurring, ensure the stability of necking in spindown process.
Described necking spinning forming part mould comprises reducing counterdie and liner core.
Further, the conveniently demoulding of described flange ring, the liner core of described necking spinning forming adopts block insert type structure, and described block insert type structure is spliced by 4 parts.
Beneficial effect: compared with traditional production technology, the spin forming method that product provided by the utility model can adopt necking in spindown to combine with necking spinning forming, avoids the inherent shortcoming such as pore, shrinkage porosite, crackle in process for machining after traditional lost-wax casting.Meanwhile, spinning forming process can ensure forming accuracy and the surface quality of flange ring part, improves yield rate.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described further.
A kind of recycle apparatus for tail gas of automotive vehicle flange loop forming mould, comprises necking in spindown and necking spinning forming two parts mould, as shown in Fig. 1,2,3,5.
Described necking in spindown part mould comprises core 10 and lower core 11; In described necking in spindown, described upper core and lower core band fluted, for fixing blank position, prevent pipe from the process of spinning roller feeding, radial deflection occurring, ensure the stability of necking in spindown process.
Described necking spinning forming part mould comprises reducing counterdie 12 and liner core 13.
Operation principle: adopt necking in spindown to combine with necking spinning forming, pipe direct forming is gone out recycle apparatus for tail gas of automotive vehicle flange ring, and this manufacturing process comprises the steps:
Necking in spindown step: consider the symmetry of spinning and enhance productivity, takes a necking in spindown to be shaped two parts.Necking in spindown process is divided into two passages, Figure 2 shows that two passage spinning undergauge process schematic.The external diameter of initial pipe is 114mm, and wall thickness is 5mm, is highly 60mm.Upper core 10 and lower core 11 compress pipe 1 and drive it to rotate, and spinning roller is feeding radially.Be the pre-undergauge spinning process of the 1st passage on the left of Fig. 1, adopt sphere spinning roller 6, the arc radius of its section is 13mm.After prewhirling, inwall and upper core 10, the lower core 11 of pipe is fitted, and the blank 2 of the outer rim that obtains prewhirling with sphere, the arc radius of pipe middle is 13mm, and internal diameter is 83.8mm.Be the pre-undergauge spinning process of the 2nd passage on the right side of Fig. 1, adopt the undergauge spinning roller 7 consistent with the outer profile size designed by flange ring, obtain the biscuit throwing after necking in spindown 3.The overall wall thickness of biscuit throwing 3 is evenly distributed, and the wall thickness in most of region is about 4.5mm.Vertical wall section is owing to being subject to the effect of contraction of core, and wall thickness change is less.And in forming process, pipe 1 is subject to the radial compression applied of the axial compressive force of core 6 and sphere spinning roller 6, undergauge spinning roller 7, and its length can slightly shorten, and is decreased to 57.3 ± 0.3mm.
Cut off step: cut off from centre by the biscuit throwing 3 after necking in spindown, obtain two necking spinning forming biscuit throwings 4.
The left side of necking spinning forming step: Fig. 2 is depicted as spinning reducing process schematic, and necking spinning forming mould mainly comprises reducing counterdie 12 and liner core 13.The biscuit throwing 4 of necking spinning forming is placed on reducing counterdie 12, drives necking spinning forming biscuit throwing 4 to rotate by liner core 13 and counterdie 12.Reducing spinning roller 8 feeding obliquely, its direction of feed is consistent with the inclination angle of the outline end of flange ring 5, is 20 ° in an embodiment.Die clearance between reducing spinning roller 8 and liner core 13 is identical with the design wall thickness of described flange ring 5, and the wall thickness of the flange ring part end in embodiment is 4mm.After necking spinning forming step, the flange reducing of biscuit throwing 4 vertical wall section can be completed.
The right side of shaping step: Fig. 2 is depicted as spinning reducing process schematic, and flange ring end, vertically to lower feeding, flattens by shaping spinning roller 9, obtain final flange ring part 5, flange ring height is 23mm, and the external diameter of bottom vertical wall section is 92.8mm, and wall thickness is 4.5mm.
In necking in spindown, upper core 10 and lower core 11 are with fluted 14, for fixing blank position, prevent pipe from the process of spinning roller feeding, radial deflection occurring, and ensure the stability of necking in spindown process.The effect of sphere spinning roller 6 makes pipe Thickness Distribution after necking in spindown more even, avoids the excessive thinning of radius area.Sphere spinning roller and undergauge spinning roller are floating type spinning roller, namely automatically can regulate the relative position between pipe in forming process.
After the shaping, conveniently flange ring part 5 demoulding, liner core 13 adopts easy-to-mount block insert type structure.As shown in Figure 4, described block insert type structure is spliced by 4 parts.
