The high precision combined mould mainly comprises a fixed core mould, fixing rings, a moving core mould, transition rings and a tail top tray, wherein the fixed core mould is provided with a through process hole, and the tail end of the fixed core mould is provided with a step hole of which the diameter is greater than that of the process hole; the tail top tray is a step shaft matched with the step hole of the fixed core mould; the cross section of the moving core mould is circular; the moving core mould is tightly sleeved outside the fixed core mould; the moving core mould is clamped by the fixed core mould and the tail top tray through the transition rings; and the fixing rings are provided with threaded holes. The fixed core mould and the tail top tray are automatically aligned and centered through guide taper angles easily and reliably, the one-way load applied by a rotating wheel is effectively overcome, and the linearity of workpieces is ensured; moreover, the high precision combined mould is low in manufacturing difficulty, high in precision and easy and convenient to assemble and disassemble, and is used reliably.
Description
Technical field
The utility model belongs to the mold machining technology field, is specifically related to a kind of high accuracy tubing necking in spindown and uses assembling die.
Background technology
The mould pressing technology be symmetrical revolving parts under rotation status metal material pressure by put line by line to face, produce simultaneously the technology of elastic-plastic deformation shaping with flowing along predetermined direction and mode.Because spinning can be produced more the metal parts near net shape (clean property); And has a stock utilization height; Advantages such as metallic fiber links up, and the product integrated quality is good, this technology being applied in auto industry, construction machinery industry and the military industry more and more widely.For satisfying complicated and diversified product spinning production demand, develop the mould that adapts with it and also must carry out thereupon.
Necking in spindown is common in the production that gas cylinder closing in, bellows etc. become the diameter product, general no mould, eccentric mandrel or the assembling die of adopting.The present invention studies a kind of specific use high accuracy reducer pipe necking in spindown and uses assembling die.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, provides that a kind of manufacture difficulty is low, precision is high, loading and unloading are simple and convenient, service-strong high accuracy tubing necking in spindown is used assembling die.
The technical scheme that the utility model adopted is: a kind of high accuracy tubing necking in spindown is used assembling die; It is mainly by fixedly core, retainer ring, movable core, transition rings and tail take over a business to form; Said fixedly core is provided with the fabrication hole that runs through, and its tail end is provided with the diameter stepped hole big than fabrication hole, said tail take over a business for the step axle of the stepped hole coupling of fixing core; The cross section of said movable core is circular; It tightly is enclosed within outside the said fixedly core, and said movable core is taken over a business clamping through be fixed core and tail of transition rings, and said retainer ring is provided with screwed hole.
As preferably, place, the aperture of said stepped hole is provided with the guiding cone angle with angle, corresponding with it, the step shaft end of taking over a business at said tail also is provided with the guiding cone angle with angle.
As preferably, the angle of said guiding cone angle is 15 degree.
As preferably, said fixedly core, movable core and tail take over a business all to adopt tool steel to process.
As preferably, said retainer ring upper screwed hole circumferentially evenly distributes along it.
The beneficial effect of the utility model is:
1, fixedly core and tail take over a business through the guiding cone angle to align centering automatically, and it is simple and reliable to feel relieved;
2, fixedly core and tail are taken over a business the centering back through the little matched in clearance of straight section, make the two keep higher rotating accuracy, axiality and rigidity, effectively overcome the unidirectional load that spinning roller applies, and guarantee the workpiece linearity;
3, at the axial arranged some holding screws of retainer ring, through holding screw workpiece pressing and the fixing core screwed, provide spinning required moment of torsion, install simple and practical;
4,, guarantee that fixedly core and tail are taken over a business the end play minimum, the difficulty of reduction processing activity core length through the length of preparation transition rings.And can be convenient for changing after the transition rings wearing and tearing, and, reduce die cost without the movable core of integral replacing;
5, assembling die processing and manufacturing difficulty is low, precision is high, loading and unloading are simple and convenient, use is reliable.
