Description

Cable-stayed type forging casting device

Technical field

The utility model relates to a kind of metal casting machine, especially the Casting Equipment of forging.

Background technology

Forging (shown in Figure 1 is near cylindrical) is the high-abrasive material that ball mill must be joined, and is widely used in the production of cement factory and other mineral products.With regard to cement, China's cement output in 2009 is 16.5 hundred million tons.Consume 240 gram forgings according to one ton of cement of every production and calculate, annual forging consumption is near 400,000 tons.

Traditional sand casting process is still adopted in the manufacturing of forging at present.The major defect of this kind technology is that energy utilization rate is difficult to improve (because the molten iron passage between dead head and each die cavity need consume more molten iron, so the molten iron utilization rate of sand casting is difficult to improve).Each ton coke can only be produced 2.8 tons of forgings; Forging per ton need consume 0.357 ton in coke.Coke per ton can melt 5 tons of molten iron, and the molten iron utilization rate is about 60%, and energy waste is bigger; And intensity of workers height.

The utility model content

The purpose of this utility model is to overcome the deficiency that the above-mentioned background technology exists, a kind of forging Casting Equipment is provided, and this equipment should be able to cast forging continuously, but has the production efficiency height, the forging quality is good and the characteristics of energy savings, and intensity of workers is little, and production cost is lower.

The utility model proposes following technical scheme:

Cable-stayed type forging casting device comprises a plurality of moulds that a frame and casting forging are used; It is characterized in that this equipment also comprises the conveyer belt by the actuating unit driving that is obliquely installed on frame; Described a plurality of mould is arranged location and installation on the conveyer belt surface according to direction of motion in-line, and the movement locus of described mould is positioned at the molten iron of the below, molten iron sprue gate of furnace cupola with direct reception thawing.

Described conveyer belt is two chains that are arranged in parallel, and each chain is walked around end to end sealing lopping behind the driven sprocket of the drive sprocket that is positioned at the frame low spot and the high point of frame respectively.

Described each mould is separately fixed on the base plate, and each base plate is hinged between two chains by a bearing pin respectively, and the both sides of each base plate are also installed two rollers respectively; The frame top also be obliquely installed a supporting mould weight and with the matched track of roller so that mould keeps straight-line track.

Described mould is that vertical vertical section is the bar-shaped trough of parallelogram, and two end faces are perpendicular to horizontal plane about it, and the angle of inclination, bottom surface is identical with the angle of inclination of track, and the following position of groove bottom is shaped on the die cavity that several cast forgings are used; The central axis of each die cavity is perpendicular to horizontal plane.

The left side of described mould is shaped on an overflow limit that overhangs outstanding left, and the surface on overflow limit is concordant with the bottom land surface; The correspondence position of mould right side is shaped on the overflow limit matched recessed.

The angle that described rack inclining is arranged is the 15-30 degree.

The below of described frame also is provided with and is beneficial to diesel oil that forging the comes off lamp that fire-cures.

Described actuating unit is the chain-wheel mechanism of driven by motor.

Use principle of the present utility model is: the energising back is mechanically activated, and it is slowly up along the track on the frame that chain drives mould; The molten iron that flow out at the furnace cupola sprue gate just in time flows directly in the die cavity of mould, and first die cavity is filled with the back molten iron and just injected second die cavity along the inclined-plane, and first mould is filled with the back molten iron and just flowed into second mould by the overflow limit; Mould continues in the slow up process, and the molten iron cooling forming in the die cavity is forging, can regulate mould translational speed (thereby solving the too much or very few problem of molten iron) by regulating motor speed; After mould moves to peak just down upset turn back make die cavity opening down, the forging in the die cavity comes off under the gravity effect automatically, by centralized collection.Then, the diesel oil lamp that fire-cures is lighted the oil smoke that the back produces die cavity is fire-cureed, and mold cavity surface is covered one deck cigarette ash, can protect the forging that mould is convenient to next moulding again can break away from mould smoothly.Above process circulates repeatedly, produces and carries out continuously.

The beneficial effects of the utility model are: the continuous casting mode that the utility model adopts, all molten iron that furnace cupola melts all can be cast as steel ingot, and the molten iron utilization rate can be near 100%, and more existing sand casting increases substantially.Through measuring and calculating (only cement is), forging per ton consumes 0.19 ton in coke; Produce 400,000 tons of calculating by national forging, can save 6.68 ten thousand tons in coke every year; Social benefit and economic benefit are very remarkable.In addition, because the full mechanization operation, the staff operates very simple (need not to join complex work such as sand, molding, moulding, oven dry), and labour intensity significantly reduces, and production cost also is minimized.

The specific embodiment

Below in conjunction with Figure of description, the utility model is described in further detail.

Cable-stayed type forging casting device comprises a plurality of moulds 6 that the casting forging is used; This equipment also comprises a frame 2, is obliquely installed the conveyer belt 7 by the actuating unit driving on frame; Described a plurality of mould is arranged location and installation on the conveyer belt surface according to direction of motion in-line, and the movement locus of described mould is positioned at the molten iron of the molten iron sprue gate 5-1 below of furnace cupola 5 with direct reception thawing.

Described conveyer belt is two chains that are arranged in parallel, and two chains mesh with drive sprocket and driven sprocket respectively; Because drive sprocket and driven sprocket are installed at various height respectively, (angle of inclination is determined as required so conveyer belt just forms the state that is in tilted layout; Recommending angle is the 15-30 degree); Each chain is walked around drive sprocket 3 and the high driven sprocket of the putting 8 end to end sealing lopping in back of frame that are positioned at the frame low spot respectively.

Described actuating unit is the chain-wheel mechanism (motor 1 is by the belt drives sprocket wheel, and sprocket wheel drives chain again) that motor 1 drives.
