Abstract
The utility model discloses a kind of ring forging molding die for blank, it is characterised in that：The ring forging molding die for blank body is cylinder, and the plane contacted with hydraulic press operating platform is arranged at bottom, and the cylinder endoporus is stepped throughhole, is made up of macropore and aperture.The beneficial effect of this programme is：Using the process of the forging dies so that forging shape is closer to finished form, and using forging die global formation, the requirement to operating personnel's specialized capability substantially reduces.Cogging efficiency improves about more than 50%, and blank disqualification rate is reduced within 2%, and labor strength substantially reduces.With forging stock quality height, the advantage that stability is good, cost is low.
Description
Technical field
Cylinder class ring forging stock technical field is the utility model is related to, more particularly, to a kind of ring forging molding blank mould
Tool.
Background technology
At present, in petrochemical system, valve is the important composition part of pipe-line system.Therefore will for the quality of valve
Ask especially high, the method that big specification valve body, bonnet use open die forging+swage forging substantially before, it is primarily present following shortcoming：1、
Forge less efficient, labor strength is big.2nd, blank quality is unstable, and workpiece is often reprocessed.3rd, operating personnel are needed to have very
High professional skill.4 blank surfaces are irregular, cause machining efficiency low.Big specification valve body, bonnet forging use certainly according to statistics
By the mode of forging+loose tooling forging, forging disqualification rate is about 15%, it is necessary to reprocess, caused by percent defective it is also of a relatively high, cause
Very big economic loss.
The content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, does not conform to for above forging method blank
This higher problem of lattice rate, we have redesigned a set of technical process, using loose tooling forging cogging+roll ring combination, there is provided
A kind of ring forging molding blank frock, frock saving material is notable, reduces cost, has saved the time of machining,
The technical scheme of use is：A kind of ring forging molding die for blank, it is characterised in that：The ring forging molding die for blank sheet
Body is cylinder, and the plane contacted with hydraulic press operating platform is arranged at bottom, and the cylinder endoporus is stepped throughhole, by macropore and
Aperture forms.Using blocking cogging+roll ring forming, blank shape remains metal streamline, improves product close to finished form
Mechanical property and service life.
The technical characteristics of the utility model also has：The macropore, aperture are conical bore, and upward, blank is placed at its big end
In the hole diameter.Macropore, aperture are provided with pattern draft, are advantageous to forging stock and deviate from mould.
The technical characteristics of the utility model also has：The blank diameter is less than the end diameter of the aperture.
The technical characteristics of the utility model also has：In the junction of the macropore and the aperture, inclined-plane is set.Successfully
Solve main rod mould and roll the ring disk face and go out groove phenomenon.
The technical characteristics of the utility model also has：Chamfering R1 is set at the macropore outside diameter, set at end diameter
Chamfering R2 is put, chamfering R3 is set at the outside diameter of the aperture.
The technical characteristics of the utility model also has：The chamfering R1 is 5mm, R2 15mm, R3 40mm.
The beneficial effect of this programme can be learnt according to the narration to such scheme, using the process of the forging dies, be made
Forging shape is obtained closer to finished form, using forging die global formation, the requirement to operating personnel's specialized capability substantially reduces.Open
Base efficiency improves about more than 50%, and blank disqualification rate is reduced within 2%, and labor strength substantially reduces.With forging stock
Quality is high, the advantage that stability is good, cost is low.
Brief description of the drawings
Fig. 1 is the frock operating diagram, and Fig. 2 is the schematic diagram after shaping, and Fig. 3 is to rush endoporus schematic diagram, and Fig. 4 is forging stock
Finished product schematic diagram, Fig. 5 are the utility model schematic diagrames, and Fig. 6 is Fig. 5 B portions enlarged drawing, wherein 1 is forging die, 1-1 is macropore, 1-
2 be aperture, and 2 be blank, and 3 be tup, and 4 be drift, and 5 be forging stock finished product, and A is plane, and R1 is macropore outside diameter chamfering, and R2 is
Macropore end diameter chamfering, R3 are the outside diameter chamferings of aperture.
Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Ring forging molding die for blank, the ring forging molding die for blank body is cylinder, and bottom has and hydraulic press operating platform
The plane A of contact, the cylinder endoporus is stepped throughhole, is made up of macropore 1-1 and aperture 1-2.Macropore 1-1, aperture 1-2
It is conical bore, upward, blank 2 is placed in aperture 1-2 diameters at its big end.The diameter of blank 2 is less than the small end of the aperture 1-2
Diameter.In macropore 1-1 and aperture 1-2 junction, inclined-plane is set.Set chamfering R1, small end straight at macropore 1-1 outside diameters
Chamfering R2 is set at footpath, chamfering R3 is set at aperture 1-2 outside diameter.Chamfering R1 is 5mm, R2 15mm, R3 are
40mm。。
Operation principle, raw material become material by hydraulic press, after increasing forging ratio, are put into mould 1, with the upset compacting of tup
Afterwards, blank ejection die, small head end puts drift 4, and hydraulic press tup is acted on drift 4, is slowly depressed into certain altitude, base
Core material is gone out in material upset, and forging stock is completed.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The variations, modifications, additions or substitutions that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In the scope of protection of the utility model.
