Description
Technical field
The utility model relates to the part processing technique field of automobile exhaust gas recirculating system, is specially a kind of large mouthful of rounding die of automobile exhaust recirculation cooling system diffuser.
Background technology
A kind of automobile exhaust recirculation cooling system diffuser, its structure is seen Fig. 1, it includes the large round mouth that an internal diameter is 84mm, diffuser is before carrying out in the road welding procedure, this large round mouth is subject to high temperature deformation, and this diffuser is had relatively high expectations to the circularity of this large round mouth when follow-up and cooling system assembling, therefore need to carry out full circle processing to this large round mouth.Added man-hour carrying out full circle in the past, and be mostly that the outer wall that is set in round mouth by shaping mould carried out simple full circle, its plastic precision is poor, is only applicable to full circle processing less demanding to circularity and that round mouth is less.
Summary of the invention
For the problems referred to above, the utility model provides a kind of large mouthful of rounding die of automobile exhaust recirculation cooling system diffuser, and it can guarantee the required precision of large mouthful full circle.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cover plate, described lower die structure comprises base plate, between described base plate and the cover plate by rolling guidance set guiding matched moulds, described cover plate bottom is fixed with the workpiece briquetting, it is characterized in that: described lower die structure also comprises the workpiece locating piece, plug and full circle slide block, described full circle slide block is provided with eight, described eight full circle slide blocks along described plug periphery respectively correspondence be installed on eight slider guides, described slider guide is fixed on the slide block base, it is outside that described workpiece locating piece inner circle is placed in described eight full circle slide blocks combination cylindrical, described slide block base is passed on described plug top, the bottom is fixed on the described base plate, the combination inner peripheral surface of described plug upper periphery face and described eight full circle slide blocks is the taper seat that cooperatively interacts, and described slide block base is connected by spring with described base plate.
It is further characterized in that: described slider guide and described full circle slide block radial outside are equipped with isometry block, in the described isometry block radial spring are installed; Described full circle slide block and described isometry block top are bolted between described slide block cover plate and the described workpiece locating piece by slide block cover plate axial restraint.
Adopt the utility model mould automobile exhaust recirculation cooling system diffuser to be carried out the shaping of large round mouth, its beneficial effect is: its plastic precision is high, wherein the workpiece locating piece is done pushing radially from large round mouth outer wall positions, eight full circle slide blocks are subjected to plug effect to large round mouth internal face, thereby finishes the full circle processing to large round mouth wall.
Description of drawings
Fig. 1 is the utility model automobile exhaust recirculation cooling system diffuser structural representation to be processed;
Fig. 2 is large mouthful of rounding die structural representation of a kind of automobile exhaust recirculation cooling system diffuser of the utility model;
Fig. 3 is the plan structure schematic diagram of lower die structure of the large mouthful rounding die of a kind of automobile exhaust recirculation cooling system diffuser of the utility model.
The specific embodiment
See Fig. 2 and Fig. 3, the utility model comprises upper die structure and lower die structure, upper die structure comprises cover plate 13, lower die structure comprises base plate 2, between base plate 2 and the cover plate 13 by rolling guidance set guiding matched moulds 11, cover plate 13 bottoms are fixed with workpiece briquetting 12, lower die structure also comprises workpiece locating piece 10, plug 3 and full circle slide block 8, full circle slide block 8 is provided with eight, eight full circle slide blocks 8 along plug 3 peripheries respectively correspondence be installed on eight slider guides 6, slider guide 6 is fixed on the slide block base 5, workpiece locating piece 10 inner circles are placed in the combination cylindrical outside of eight full circle slide blocks 8, slide block base 5 is passed on plug 3 tops, the bottom is fixed on the base plate 2, and the combination inner peripheral surface of plug 3 upper periphery faces and eight full circle slide blocks 8 is the taper seat that cooperatively interacts, and slide block base 5 is connected by spring 4 with base plate 2.Slider guide 6 is equipped with isometry block 7 with full circle slide block 8 radial outsides, and radial spring 16 is installed in the isometry block 7; Full circle slide block 8 passes through slide block cover plate 9 axial restraints with isometry block 7 tops, is bolted between slide block cover plate 9 and the workpiece locating piece 10.Among Fig. 2,1 is feet; Among Fig. 3,14 is limited post, and 15 is inner guiding post.
The below specifically describes and adopts the utility model mould to carry out the process of large mouthful of full circle of automobile exhaust recirculation cooling system diffuser: treat that the shaping workpiece is positioned over the interior location of die cavity of workpiece locating piece 10, upper die structure and lower die structure under the drive of punch press by rolling guidance set guiding matched moulds, in the matched moulds process, upper die structure, slide block base 5 and be fixed in lower die structure part pressurized on the slide block base 5, spring 4 pressurizeds, so that cooperating with the combination internal conical surface of eight full circle slide blocks 8, the top outer conical surface of plug 3 contacts, eight outer moving that full circle slide block 8 is done radially along slider guide 6 by the effect of plug 3, with workpiece locating piece 10 the large round mouth wall of workpiece is carried out radial compression, finish full circle processing; After the full circle completion of processing, the punch press unloading is to the pressure of upper die structure, spring 4, radial spring 16 resiliences, the radial compression that plug 3 is removed eight full circle slide blocks 8, the screen resilience effect that eight full circle slide blocks 8 are subjected to radial spring 6 along slider guide 6 do radially in move, thereby remove the constraint to the large round mouth inwall of workpiece, make things convenient for the taking-up of workpiece.
