Abstract
The utility model relates to a novel round die vulcanized V-type belt die, and comprises an upper die, more than two middle dies and lower dies; the axial top part of each middle die is an upwardly convex ring, and the axial bottom part thereof is a concave step ring groove, two adjacent middle die shafts face upwards, the convex ring of the middle die at the upper part is positioned in the concave step ring groove of the middle die at the bottom part, an inner groove matched with the outer surface of a V-type belt is formed on the surface of the matching point of the convex ring and the concave step ring groove of two adjacent middle dies, the bottom part of the upper die is the concave step ring groove, the convex ring at the top part of the middle die close to the bottom part of the upper die is positioned in the position of the concave step ring groove at the bottom part of the upper die, and the bottom part of the lower die is the upwardly convex ring, and the convex ring at the top part of the lower die is positioned in the position of the concave step ring groove at the bottom part of the middle die close to the convex ring of the top part of the lower die. The lining length of the novel die is 2325 and can be shortened by 0.6 percent; the vulcanized belt is used to perform experiment for 200 hours, the change rate of the outer perimeter is only 0.6 percent, and the fatigue lifetime is 4 times of traditional vulcanized die. Therefore, the novel belt die reaches the level of Japan BANDO belts. (Experimental method: a drive wheel drives at the speed of 1750, the power is 6 KW and the tension is 900 N, which are higher than the GB/T12735-1991national standard.
Description
Technical field
The utility model relates to the mould of V-shape belt circle mould sulfuration usefulness.
Background technology
The mode of existing V-shape belt sulfuration has three kinds: compression molding, the sulfuration of circle mould, drum-type sulfuration.Three kinds of vulcanization respectively have pluses and minuses, and advantage such as circle mould sulfuration is even, attractive in appearance, efficient and enjoy high praise, the existing scope of application is very wide, also is the main sulfuration means of domestic and international production firm.Circle mould sulfuration is exactly that ready-made made-up belt is enclosed within on the mould successively, and then puts gum cover, hangs in the vulcanizing tank, covers cover plate, the cover that closes, and logical external pressure reaches 0.8-1.0Mpa, presses 0.42MPa in logical again, makes made-up belt vulcanize compression forming.From said process just as can be seen, made-up belt is enclosed within on the mould, all sizes just can only be more than or equal to all sizes in the mould in the made-up belt so, inside compression forming during sulfuration, vulcanize that the belt percentage elongation big slightly, belt influence to general use is little, as ordinary straps such as A, B, C, D, E, big, the demanding belt of some loads is then shown the use elongation.
Summary of the invention
In order to reduce the percentage elongation of belt, improve the service life of belt, the problem of elongation appears using in existing circle mould sulfuration belt, and the utility model provides a kind of new construction circle mould sulfuration V-shape belt mould.
Concrete improvement design is as follows:
New construction circle mould sulfuration V-shape belt mould comprises circular patrix, circular middle mould and circular counterdie more than two, it is characterized in that:
Mold shaft is the bulge loop that raises up to the top in described, and it axially corresponds to indent step annular groove in the bottom,
Described two adjacent middle mold shafts make progress, and the bulge loop of mould is arranged in the indent step annular groove place of bottom mould in the top; The bulge loop of two adjacent middle moulds and surface, indent step annular groove cooperation place form the inner groovy that cooperates with the V-shape belt outer surface;
Described patrix bottom is an indent step annular groove, and the top bulge loop of adjacent with it middle mould is positioned at the indent step annular groove place of patrix bottom;
Described counterdie top is the bulge loop that raises up, and described counterdie top bulge loop is arranged in the indent step annular groove place of adjacent with it mould bottom.
Useful technique effect of the present utility model is: 1, can reduce the circumferential length of strength layer, as HC2345 traditional moulds sulfuration, winding displacement length is 2340mm, and is 2325 with the utility model new construction mould winding displacement length, can shorten 0.6%.
2, when doing fatigue life test, with SB54 is example, and the belt of traditional moulds sulfuration was tested 50 hours, the outer perimeter rate of change is 2%, and the belt of new construction sulfuration was tested 200 hours, and the outer perimeter rate of change only is 0.6%, and also be its 4 times fatigue life, (test method: driving wheel passes speed 1750 to be changeed the level of approaching Japanese slope east belt, power 6KW, tension force 900N is higher than the GB/T12735-1991 national standard).

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, new construction circle mould sulfuration V-shape belt mould comprises circular patrix 1, circular middle mould 2 and circular counterdie 3 more than two.
Two adjacent middle mold shafts make progress, and the bulge loop of mould is arranged in the indent step annular groove place of bottom mould in the top; The bulge loop of two adjacent middle moulds and surface, indent step annular groove cooperation place form the inner groovy that cooperates with V-shape belt 4 outer surfaces, see Fig. 5;
Patrix 1 bottom is an indent step annular groove, and the top bulge loop of adjacent with it middle mould is positioned at the indent step annular groove place of patrix bottom;
The utility model mould collar extension seals, and internal orifice opens wide, and sees Fig. 2.
During operation made-up belt is put into mould successively from the inside, the every middle mould 2 that closes is successively put into processed V-shape belt 4 inboard of made-up belt then, and the cover plate up and down that closes is seen Fig. 5, puts into jar, and cover closes.In gum cover, feed steam 0.8-1.0MPa, make its by gum cover to the outside tension force of made-up belt, make strength layer be subjected to very big tension force.Feed the steam of 0.4MPa as curing temperature to the mould outside.
