Abstract
The utility model discloses a train wheel forming mould which comprises an upper mould (1), a lower mould (2) and a circular mould (3), wherein the lower mould (2) is positioned in the circular mould (3); a circular ring-shaped upper boss (4) is formed on the lower surface of the upper mould (1), and takes the center of the lower surface of the upper mould (2) as a center; a groove is formed in the center of the lower surface of the upper mould (1); a support pillar (5) is arranged at the center of the lower mould (2); a circular ring-shaped lower boss (6) taking the support pillar (5) as the center is arranged on the lower mould (2); a through hole running through the lower mould (2) is formed between the lower boss (6) and the support pillar (5); and a through hole running through the lower mould (2) is formed between the lower boss (6) and the circular mould (3). The train wheel forming mould with the structure can enable formed wheels to be easily taken out, so that the formed wheels are prevented from being damaged.
Description
Technical field
The utility model relates to train wheel and makes the field, specifically is the train wheel shaping dies.
Background technology
At present, the manufacturing of countries in the world train wheel except that a small amount of employing cast steel, is to use the steel ingot base mostly, through forging and pressing and rolling after machined form.The technological process of existing Russia newly-built wheel shaping in this year production line: steel billet is successively on three hydraulic presses; Jumping-up, impression and four work steps of die forging forge into forging in jumping-up, ring; Hole enlargement on milling train again; Punching on a hydraulic press, press-bending and correction at last, per hour 120 of the Gao Shida of productivity ratio.And the wheel forming technology flow processs that state adopted such as day, moral, English, U.S.A: blank that steel ingot is processed earlier on same hydraulic press through blocking and two work step forging of die forging; After rolling hole enlargement; Per hour 80 of punching and press-bendings on another hydraulic press, productivity ratio.Conventional molds is shaped at wheel, and the back is difficult takes out the shaping wheel, and adopts outside special device to take out the shaping wheel, has not only increased cost, also possibly make the shaping wheel impaired.
The utility model content
The utility model provides a kind of train wheel shaping dies; Having solved wheel shaping dies in the past is difficult for the shaping wheel is taken out; And if adopt outside special device to take out the shaping wheel, not only increase cost, also possibly make the impaired problem of shaping wheel.
The utility model is that the technical solution problem mainly realizes through following technical scheme: the train wheel shaping dies; Comprise upper die and lower die and ring mould, counterdie is positioned at the ring mould, and the lower surface of said patrix is provided with circular convex platform; Said convex platform is the center of circle with the center of the lower surface of patrix; The center of the lower surface of said patrix is provided with a groove, and the center of said counterdie is provided with a support column, and also being provided with on the said counterdie with the support column is the circular lower convex platform at center; Be provided with the through hole that runs through counterdie between said lower convex platform and the support column, also be provided with the through hole that runs through counterdie between lower convex platform and the ring mould.
The cross section of said groove and support column be shaped as circle, the area of bottom portion of groove is equal to or greater than the area at support column top.
Being shaped as of the longitudinal section of said groove and support column is trapezoidal.
The equal diameters of said convex platform and lower convex platform, and convex platform and lower convex platform are positioned on the same vertical straight line.
The angle of the center line of said patrix and the center line of counterdie is 1.5 °.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model is provided with through hole on counterdie; Only need push rod be passed through hole when taking out the shaping wheel; And then wheel ejected get final product; Greatly facilitate the taking-up of wheel like this, operate also very simply, also avoided simultaneously adopting other taking-up instruments that wheel is caused damage.

Fig. 2 is the profile of the utility model.
Pairing Reference numeral is in the accompanying drawing: 1, patrix, 2, counterdie, 3, the ring mould, 4, convex platform, 5, support column, 6, lower convex platform.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
Like Fig. 1, shown in Figure 2; The utility model comprises patrix 1, counterdie 2 and ring mould 3, and counterdie 2 is positioned at ring mould 3, and the lower surface of patrix 1 is provided with circular convex platform 4; Convex platform 4 is the center of circle with the center of the lower surface of patrix 1; The center of the lower surface of patrix 1 is provided with a groove, and the center of counterdie 2 is provided with a support column 5, and also being provided with on the counterdie 2 with support column 5 is the circular lower convex platform 6 at center; Be provided with the through hole that runs through counterdie 2 between lower convex platform 6 and the support column 5, also be provided with the through hole that runs through counterdie 2 between lower convex platform 6 and the ring mould 3.
The cross section of the groove of present embodiment and support column 5 be shaped as circle, the area of bottom portion of groove is equal to or greater than the area at support column 5 tops.
Being shaped as of the longitudinal section of the groove of present embodiment and support column 5 is trapezoidal.
The convex platform 4 of present embodiment and the equal diameters of lower convex platform 6, and convex platform 4 is positioned on the same vertical straight line with lower convex platform 6.
The angle of the center line of the patrix 1 of present embodiment and the center line of counterdie 2 is 1.5 °.
The operation principle of the utility model is: at first steel billet is put into counterdie 2; Counterdie 2 moves upward and contacts with the patrix that rotates 1, and support column 5 inserts in the groove of patrix 1, falls counterdie 2 then; Through the through hole on the counterdie 2 blank that is shaped is ejected, accomplish wheel and be shaped.
As stated, then can realize the utility model well.
