Description
Technical field
The present invention relates to a kind of metal material processing technique manufacturing method, particularly a kind of manufacture method of monel end socket.
Background technology
Monel is a kind of excellent structural timber, and along with the expansion year by year of its consumption, the application in the processing and manufacturing of various engineering structure and equipment gets more and more.Plastic deformation difference is there is due to during monel cold forming, easy to crack, and the shortcoming such as screen resilience is large, make its formed machining more difficult, if method is improper or technique is unreasonable, often cause workpiece to meet technical requirement, be shaped comparatively difficulty, as easy as rolling off a logly cause the problem such as to tear during shaping, cause and scrap.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, thus a kind of manufacture method of monel end socket is provided, punching course is stablized, be out of shape even, smooth and easy, the hot-working system determined is feasible, and technological parameter is reasonable, and workpiece size controls better, metal streamline distribution is reasonable, stable performance.
According to technical scheme provided by the invention, a kind of manufacture method of monel end socket, comprising:
(1), Design of Dies: during Design of Dies, larger factor is affected mainly to forming process and product size: patrix pressure head diameter D
1, counterdie draw ring outlet diameter D
2, the gap Z of upper and lower intermode, counterdie draw ring fillet R selects;
Patrix: the end socket after punching press is in cooling procedure, and metal contracts, makes end socket diameter reduce.Therefore, during patrix design, the size of patrix pressure head diameter should suitably be strengthened.Patrix pressure head diameter D
1=Do (1+ ε %), in formula: Do is end socket theoretical diameter, ε is the average shrinkage amount of end socket diameter, gets 0.5 ~ 0.7%.Upper mold materials: cast steel;
Counterdie: main consideration counterdie draw ring outlet diameter D
2with counterdie draw ring fillet R, they ensure the critical size carried out smoothly that is shaped.Counterdie draw ring outlet diameter D
2=D
1+ 2Z, Z are the gap of upper and lower intermode.The factor such as amount of swelling on the nominal thickness of blank, the plus tolerance of sotck thinkness and shaping rear head top is depended in the determination of Z value.Size the counting for much to forming quality of Z and R value.Z, R are too small, radial drawing power when making shaping increased, stretch forming difficulty, and the Reducing thickness of workpiece is increased, time serious, cause workpiece to tear.Excessive Z, R, easily cause wrinkling.During design, Z=1.06t, R=(2.5 ~ 3.5) t, t are blank thickness of slab.Lower mold materials: internal mold cast iron, outer moulded steel;
