Description

Current-following inoculation agent feeder

Technical field

The utility model relates to casting with the cast field of tool, relates in particular to current-following inoculation agent feeder.

Background technology

The disappearance mould that with casting pig, spheroidal graphite cast-iron is material needs add granular inovulant at molten iron when cast; With refinement graphite, improve the tensile strength and the percentage elongation of nodularization and cutting ability, raising material; The addition of inovulant is generally 0.07% ~ 0.15%; Prior art is before cast, earlier a certain amount of graininess inovulant to be put into casting ladle after casting ladle is annotated molten iron, to pour into a mould again; Inovulant can not be evenly mixed with molten iron like this, when causing beginning to pour into a mould in the molten iron content of inovulant too much can make foundry goods produce slag inclusion or field trash, can not play the effect that improves material property and the content of inovulant is very few in the molten iron when pouring into a mould finally.

Summary of the invention

For addressing the above problem; The utility model provides current-following inoculation agent feeder; Put into feeder to inovulant; Feeder also adds inovulant to cup in proportion in the cup pouring molten iron of casting ladle above the disappearance mould, makes that inovulant and molten iron are evenly mixed, ratio is suitable, with refinement graphite, improve the tensile strength and the percentage elongation of nodularization and cutting ability, raising material.

For reaching above purpose, the utility model is realized through following technical scheme: the current-following inoculation agent feeder of the utility model comprises the upper barrel body of drum shape; Weld the lower barrel body of an inversed-cone shape in the upper barrel body bottom, in the L shaped upper lug of lower barrel body periphery upper end welding, described upper lug is connected with pull bar through minor axis; Upper lug and minor axis are tight fits, and minor axis and pull bar are movingly, and the tail end of described pull bar connects major axis through minor axis; Hole and minor axis that the pull bar tail end is corresponding are tight fits, and minor axis and major axis are movingly, and the long axis frame of a Y shape is respectively welded in the upper and lower of the inwall of said upper barrel body; An axle sleeve is all welded at the center of long axis frame in the upper and lower, and the endoporus of axle sleeve and major axis be for movingly, lug in the welding of the top of said lower barrel body outer wall; Middle lug is connected with connecting rod through minor axis, and middle lug and minor axis are tight fit, and minor axis and connecting rod are for movingly; Welding one holder is pulled in the connecting rod lower end, and the opposite side welding of said lower barrel body outer wall bottom is lug down, and following lug is connected with plate washer through minor axis; Following lug and minor axis are tight fit, and minor axis and plate washer are movingly, said lower barrel body bottom welding one base plate; The hole of one ￠ 20 is set at the center of base plate, and at three supports of lower barrel body outer wall middle part welding, these three supports are for being uniformly distributed with; When to disappearance mould pouring molten iron, earlier move on to disappearance mould cup place to current-following inoculation agent feeder, at casting ladle in cup injection molten iron; Operating personnel upwards lift rear supporting plate to connecting rod and plate washer is sagging, and inovulant adds in the cup through ￠ 20 holes at base plate center, make inovulant and molten iron in running channel, can flow into the disappearance mould by the evenly mixed back of ratio; Like ￠ 20 hole plugs at base plate center, then operating personnel upwards lift pull bar, major axis is moved down and smash ￠ 20 holes logical; When cast finished, operating personnel pressed down connecting rod, and then supporting plate drive baffle plate blocks ￠ 20 holes at base plate center.

The beneficial effect of the utility model is: feeder is also pressed ratio to cup (molten iron is calculated with the weight of foundry goods in the cup pouring molten iron of casting ladle above the disappearance mould; Inovulant calculates with place, ￠ 20 holes average discharge and the product of the time of interpolation) the interpolation inovulant; Reach that inovulant and molten iron are evenly mixed, ratio is suitable, thus make castings material the graphite refinement, improved nodularization and cutting ability, improved tensile strength and percentage elongation.

The specific embodiment

In order to deepen understanding to the utility model, will combine accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Like Fig. 1, shown in 2: the current-following inoculation agent feeder of the utility model, comprise the upper barrel body 1 of drum shape, weld the lower barrel body 2 of an inversed-cone shape in upper barrel body 1 bottom; The L shaped upper lug 4 of periphery upper end welding at lower barrel body 2; Upper lug 4 is connected with pull bar 5 through minor axis 13, and upper lug 4 is tight fits with minor axis 13, and minor axis 13 is movingly with pull bar 5; The tail end of pull bar 5 is connected with major axis 6 through minor axis 13; Hole and minor axis 13 that pull bar 5 tail ends are corresponding are tight fits, and minor axis 13 is movingly with major axis 6, and the long axis frame 7 of a Y shape is respectively welded in the upper and lower of described upper barrel body 1 inwall; An axle sleeve 8 is all welded at long axis frame 7 centers in upper and lower, and the endoporus of axle sleeve 8 and major axis 6 are for movingly.Lug 11 in the top welding of said lower barrel body 2 outer walls, middle lug 11 is connected with connecting rod 9 through minor axis 13, and middle lug 11 is a tight fit with minor axis 13; Minor axis 13 and connecting rod 9 are for movingly, and welding one holder in connecting rod 9 lower ends pulls 10, a pair of lug 16 down of the opposite side welding of said lower barrel body 2 outer wall bottoms; Following lug 16 is connected with plate washer 12 through minor axis 13, and following lug 16 is a tight fit with minor axis 13, and minor axis 13 is movingly with plate washer 12; Weld a base plate 3 in the bottom of lower barrel body 2, the center of base plate 3 is provided with the hole 14 of a ￠ 20, three supports 15 of outer wall middle part welding of lower barrel body 2; These three supports 15 are for being uniformly distributed with; When to disappearance mould pouring molten iron, earlier move on to disappearance mould cup place to current-following inoculation agent feeder, at casting ladle in cup injection molten iron; It is sagging with plate washer 12 that operating personnel upwards lift rear supporting plate 10 to connecting rod 9; Inovulant adds in the cup through ￠ 20 holes 14 at base plate 3 centers, makes inovulant and molten iron in running channel, can flow into the disappearance mould by the evenly mixed back of ratio (molten iron calculates with the weight of foundry goods, and inovulant calculates with place, ￠ 20 holes average discharge and the product of the time of interpolation).Stop up like the ￠ at base plate center 20 holes 14, then operating personnel upwards lift pull bar 5, major axis 6 is moved down and smash ￠ 20 holes 14 logical.When cast finished, operating personnel pressed down connecting rod 9, and then supporting plate 10 drive baffle plates 12 block ￠ 20 holes 14 at base plate center.

When the enforcement of the utility model can make the cup pouring molten iron of casting ladle above the disappearance mould; Feeder is also pressed ratio to cup and is added inovulant, evenly mixes the graphite refinement that makes castings material, has improved nodularization and cutting ability, has improved tensile strength and percentage elongation thereby reach inovulant and molten iron.
