Abstract
The utility model discloses a novel metal-stream inoculation device. The device consists of a hopper, a limiting nozzle, choke plugs and a steel wire rope, wherein the limiting nozzle is connected together with discharging holes through connecting components; the discharging holes are conical; the chock plugs are matched with the conical surfaces of the discharging holes; the centers of the chock plugs are provided with holes; the steel wire rope is placed into holes of the chock plugs; the upper end of the steel wire rope is inserted into a hole in a hollow metal pipe of a hopper bracket, and passes through the center of the metal pipe; the lower end of the steel wire rope passes through the limiting nozzle. The inoculation device is erected at a proper position, and is used for performing metal-stream inoculation on molten iron during casting of the molten iron, thereby achieving a good inoculation effect, effectively enhancing the strength of castings and improving the comprehensive performance of castings. The device has the advantages of easiness and convenience in operation, wide application range and low cost.
Description
Technical field
The utility model relates to a kind of cast iron cast inoculation device, while being specially adapted to hand dropping single-piece large-tonnage foundry goods, uses.
Background technology
" current-following inoculation " is technical process crucial in castings production, but how in the best opportunity, with optimal dose and mode, to add inovulant, is a technique difficult problem that perplexs for a long time casting industry.Many enterprises are for solving the difficult problem of " current-following inoculation ", and cost huge fund is bought import fully-automatic equipment.And these equipment are often only applicable to streamline moulding, foundry goods batch production, at the hand dropping scene of single-piece large-tonnage foundry goods, cannot use.
And adopting in the factory of manual casting ladle cast, although also adopted current-following inoculation, adopting screw feeding or pneumatic reinforced mode more, complex structure, poor stability, cannot effectively control the parameters such as delivery rate, feed time and feed total amount.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, and a kind of scene of pouring into a mould by hand that is suitable for is provided, and can accurately control the current-following inoculation device of delivery rate, feed time and feed total amount.
The said current-following inoculation device of the utility model is by limitting material mouth, attaching parts, discharging opening, plug, steel wire rope and hopper to form.Limit material mouth is linked together by attaching parts with discharging opening, and discharging opening is taper shape, has the plug of identical coning angle and the taper seat of discharging opening matches; Plug center is provided with the fixedly hole of steel wire rope, is provided with the screw that is fixed on steel wire rope by screw on plug; Steel wire rope is placed on plug fixedly in the hole of steel wire rope, and the upper end of steel wire rope penetrates the hole on the guiding hollow metal tube that doubles as hopper base, and passes from hollow metal tube hub, and steel wire rope lower end passes from limit material mouth.The hole of said fixedly steel wire rope, can be through hole, can be also obstructed hole.
The said current-following inoculation device of the utility model, has feature simple to operate, widely applicable, with low cost.By steel wire rope, drive plug to move up and down, can control flexibly the switch of discharging opening.Be equipped with after the limit material mouth of different pore size, only need to change limit material mouth and can change inovulant blanking velocity.
Accompanying drawing explanation:
Accompanying drawing 1: current-following inoculation device schematic diagram;
Accompanying drawing 2: limit material mouth;
Accompanying drawing 3: discharging opening;
Accompanying drawing 4: the plug with through hole;
Accompanying drawing 5: the plug with blind hole.
The specific embodiment
The said current-following inoculation device of the utility model, comprises that limit material mouth 1, attaching parts 2, discharging opening 3, plug 4, steel wire rope 5 and hopper 6 form.Limit material mouth 1 with discharging opening 3 by attaching parts 2(as socket cap screw) with removably, link together, therefore, can there is by uses the limit material mouth 1 adjusting discharging speed of different pore size size; Discharging opening 3 is conical, and its taper seat coordinates with the plug 4 with identical coning angle, and fit clearance is less than 0.1mm; Plug 4 centers are provided with the fixedly hole 8 of steel wire rope, and plug is provided with the screw 10 that is used for fixing steel wire rope 5 in two ends Shang Xia 4, and steel wire rope 5 is placed in the hole 8 of plug 4, is screwed on plug 4; Double as and on the hollow guiding metal tube 7 of hopper 6 supports, arrange porosely 9, the upper end of steel wire rope 5 penetrates the hole 9 on hollow metal tube 7, and passes from metal tube 7 centers, and steel wire rope 5 lower ends pass from limit material mouth 1.Plug 4 moves up and down by the drive of steel wire rope 5.Said attaching parts 2 can be socket cap screws, also the fastening screw of energy of other shape.
While using the said current-following inoculation device of the utility model, first the clogging discharging opening 3 of plug 4 being left behind, in hopper 6, add appropriate random inoculant, then this inoculation device frame (is needed only and can guarantee that inovulant drops on the position on molten iron stream on casting ladle or cup, be not limited to above-mentioned two), during operator is hand held by upper and lower two ends steel wire rope 5 from the side, ready.When cast starts, operator pulls upper end steel wire rope 5a, and plug 4 is moved up, and opens discharging opening 3, and it is upper that inovulant drops on molten iron stream equably, enters die cavity, the effect of performance current-following inoculation.After casting complete, unclamp upper end steel wire rope 5, pull lower end steel wire rope 5b, block discharging opening 3, inovulant stops falling.
This inoculation device is simple to operate, widely applicable, with low cost.By steel wire rope, drive plug to move up and down, can control flexibly the open and close of discharging opening.Be equipped with after the limit material mouth of different pore size, only need to change limit material mouth and can change inovulant blanking velocity.
Claims (4)
1. a Novel stream inoculation device, by limit material mouth, attaching parts, discharging opening, plug, steel wire rope and hopper, formed, it is characterized in that, limit material mouth and discharging opening are linked together by attaching parts, discharging opening is conical, have the plug of coning angle and the taper seat of discharging opening matches, plug center is provided with the fixedly hole of steel wire rope, is provided with the screw that is used for fixing steel wire rope on plug; Steel wire rope is placed on plug fixedly in the hole of steel wire rope, and the upper end of steel wire rope penetrates the hole on hopper base hollow guiding metal tube, and passes from metal tube center, and steel wire rope lower end passes from limit material mouth.
