Abstract
The invention provides forge forming process for a shaking seat of a bogie and the shaking seat in forge forming. The novel forge molding process for the shaking seat includes forge molding of high-quality alloy steel, the shaking seat in forge forming comprises a spring support plate and a lower support seat, the lower support seat of the shaking seat is mounted below the spring support plate, a bump is disposed on a carrying tabletop of the spring support plate, the lower support seat 3 is an annular support consisting of four support legs, and the spring support plate and the lower support seat are made of 25MnCrNiMoA rolled round steel by means of forging. Production efficiency of the shaking seat can be obviously improved by the aid of the forge molding process, and the produced shaking seat for the bogie is applicable to meeting requirements of running of a high-speed railway vehicle.
Description
Technical field
The present invention relates to a kind of processing method and product of railway product, especially relate to a kind of bogies for railway vehicles with the seat that shakes that shakes a forging molding process and forging molding.
Background technology
Shaking seat is a vitals in the bogies for railway vehicles, be installed between the spring load plate of bogie of car bogie side frame and bearing spring, and be a main stressed member, so requirement on the make is quite high.At present bogies for railway vehicles uses and shakes seat and cast as E level steel and shake seat; It all is to cast out through cast steel that seat is shaken in this casting; Carry out annealing in process through heat treatment again, also need carry out harmless visiting of magnetic and check look at whether casting flaw is arranged; So make cumbersomely, and qualification rate is not high.
Completion along with railway construction in China heavy duty speed-raising; Cast steel shakes seat because of casting factor; Defectives such as can't avoiding having pore, shrinkage porosite, be mingled with, crackle, service life are short, and the existence of these defectives constitutes potential potential safety hazard to rolling stock heavy duty high-speed cruising.So need badly further bogie is improved with shaking seat with the manufacturing approach of shaking seat and to bogie.
Through domestic patent retrieval, do not have to find to have separately to the patent application of shaking seat in the bogies for railway vehicles.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; Propose a kind of production efficiency of shaking seat that can obviously improve and overcome above-mentioned deficiency simultaneously, a kind of bogie that is applicable to high-speed railway vehicle operation needs is with shaking a forging molding process and a kind of bogie with shaking seat.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: a kind of bogie adopts and forges manufacture craft making bogie with shaking seat with shaking a forging molding process; Comprise (1) the selection of material: forge and to shake seat and will select the superior alloy steel steel billet for use, said superior alloy steel steel billet will with the E level cast steel material intensity of present use quite or be higher than E level cast steel material;
(2) accurately calculate material and blanking: it is heavy accurately to calculate material based on heat forging drawing, avoids die cavity to be not fully filled or beats unreal;
(3) base: forge on hammer anvil with 1-3T flat-die hammer after the round base after the blanking is heated to 950-1150 ℃, make round base preliminary deformation, obtain the rectangle blank; Because shake two ear head of seat, it is more to account for material, therefore, press shoulder after the employing gas cutting ear more again;
(4) finish-forging: forge with 6500-9000T friction press putting into forging mold after the blank heating, hit 2-3 shapings, the design of forging mold will help metal flow, and die cavity can be full of, and does not produce folding phenomenon;
(5) cut edge: cut overlap on the forging with 800-1200T friction press;
(6) normalizing: as conditioning treatment, crystal grain thinning eliminates stress, for final heat treatment provides suitable structural state;
(7) ball blast: remove the forging surface scale with special equipment;
(8) flaw detection: whether the inspection forging exists crackle or bark pocket;
(9) shaping: on hydraulic press, smooth with shaping mould and special tooling.
(10) machining: cause surplus to carry out machine to the place of drawing requirement processing and two ear's pattern drafts and add;
(11) polishing.
As a further improvement on the present invention, also carried out following steps after said step 10 polishing:
(12) heat treatment: forging is heat-treated the comprehensive mechanical performance of giving full play to steel alloy with the special specification of heat treatment of formulating;
(13) ball blast: surface peening improves the fatigue strength that shakes seat;
(14) flaw detection.
As a further improvement on the present invention, the preferred described superior alloy steel steel billet of step 1 is selected 25MnCrNiMoA milling round steel or 35CrMo for use;
As further improvement of the present invention, 930 ℃ of the preferred described normalizing temperatures of step 6 temperature retention time 3-4 hour, are come out of the stove and are carried out air cooling.
The present invention also provides a kind of seat that shakes according to above-mentioned manufacturing process forging molding; This shakes seat by the superior alloy steel forging molding; Comprise spring planet and following supporting seat, the said following supporting seat that shakes seat is installed in the spring planet below, and said spring planet cushion cap face is provided with prominent navel.
As further improvement of the present invention, preferred said supporting seat down is an annular ledge, and said annular ledge comprises four feets.
As further improvement of the present invention, described forging molding what shake that seat adopts is that 25MnCrNiMoA milling round steel or 35CrMo forge and form.
In sum, a kind of bogie of the present invention with shake a Forging Technology and a kind of forging molding shake that seat is avoided having pore, shrinkage porosite, is mingled with, defective such as crackle, service life are short and obviously improve the production efficiency of shaking seat.
