Description
Technical Field
The invention relates to the field of die casting machine accessories, in particular to an automatic scum striking soup ladle.
Background
In the process of processing and forming aluminum products, a spoon is needed to scoop up molten aluminum, then the spoon pours the molten aluminum into a mold, and the molten aluminum is cooled and formed into related aluminum products in the mold.
Because the surface of the molten aluminum is easy to form an oxide film when being contacted with air, oxidation scum can be formed on the surface of the aluminum liquid, and thus when the aluminum liquid is poured into the mold by the spoon, the oxidation scum can also enter the mold together, thereby influencing the molding quality of aluminum products in the mold.
Disclosure of Invention
The present invention is intended to provide an automatic scumming ladle to reduce the amount of scumming poured into the mold.
In order to achieve the purpose, the invention adopts the following technical scheme: automatic scumming soup ladle, including the soup ladle body, be equipped with the liquid outlet on the soup ladle body, the inside of soup ladle body is equipped with the baffle, and the baffle rotates to be connected on the top of soup ladle body, and liquid outlet and baffle set up relatively.
The principle and the advantages of the scheme are as follows: when the automatic scum beating soup ladle pours the aluminum liquid, the aluminum liquid is poured out from the liquid outlet by rotating the soup ladle body by a certain angle. Because the baffle is arranged opposite to the liquid outlet, the oxidation scum on the surface of the aluminum liquid is blocked by the baffle while the aluminum liquid flows out, so that the poured aluminum liquid is cleaner, and the quality of the aluminum liquid and the product quality are ensured.
In addition, the baffle in this scheme rotates to be connected on the soup ladle body, therefore the soup ladle body when the slope is fallen aluminium liquid, the baffle can keep vertical state, and the baffle can not follow the slope of soup ladle body and slope, has avoided the bottom of baffle and the surface separation of aluminium liquid, has realized that the baffle can insert aluminium liquid level all the time to can block aluminium liquid dross on the surface, can not receive the influence that the soup ladle body emptys.
Preferably, as an improvement, the soup ladle body is provided with a liquid inlet. Through setting up the inlet, when automatic scumming soup ladle was scooping up aluminium liquid, aluminium liquid enters into this internal from the inlet.
Preferably, as an improvement, a rotating shaft is connected between the top of the spoon body and the baffle. From this, through setting up the rotation axis, realized the rotation of baffle on the soup ladle body top.
Preferably, as an improvement, a protrusion is arranged on the inner wall of the bottom of the liquid outlet, and a liquid channel is formed between the protrusion and the bottom of the baffle. When the ladle body pours the aluminium liquid, the aluminium liquid flows through from the liquid passage between the bottom of baffle and the bulge. Along with the pouring of the aluminum liquid into the mold, the amount of the aluminum liquid in the mold gradually increases, the aluminum liquid in the mold gradually approaches to the mold opening, and the aluminum liquid in the mold is easy to splash or overflow from the mold opening. And when empting aluminium liquid through this scheme, the inclination grow gradually of soup ladle body, because the setting of bulge, liquid channel between the bottom of baffle and the bulge diminishes gradually like this to make aluminium liquid constantly diminish from the speed that flows out in the liquid outlet, avoided aluminium liquid too big and empty in the outside of mould from liquid outlet outflow speed, avoided flowing into aluminium liquid speed in the mould too big and make aluminium liquid spill over, also avoided the velocity of flow of aluminium liquid too big and arouse the great splashing of aluminium liquid in the mould.
Preferably, as an improvement, an arc-shaped concave part is arranged on the inner wall of the bottom of the liquid outlet, and a liquid channel is formed between the concave part and the bottom of the baffle; the circle center of the concave part is positioned on the rotation center of the baffle.
Preferably, as an improvement, the baffle plate comprises a fixed part and a sliding part, the sliding part is vertically connected to the fixed part in a sliding manner, the sliding part extends out of the bottom of the baffle plate, the fixed part is fixedly connected with a fixed plate positioned above the sliding part, a tension spring is connected between the fixed plate and the sliding part, and the sliding part is connected with a first magnet block; the top of the soup ladle body is fixedly connected with an arc-shaped plate, the arc-shaped plate is positioned above the baffle, the inner wall of the arc-shaped plate is fixedly connected with a plurality of second magnet blocks, the second magnet blocks and the first magnet blocks are mutually repellent, and the plurality of second magnet blocks are sequentially arranged and distributed on the inner wall of the arc-shaped plate along the arc-shaped edge of the arc-shaped plate; repulsion between the second magnet piece and the first magnet piece becomes larger along with the increase of the dumping angle of the spoon body. With the arrangement, when aluminum liquid is poured, the pouring angle of the soup ladle body is gradually increased, the first magnet block above the baffle plate is opposite to the different second magnet block, the repulsive force between the first magnet block and the second magnet block is continuously increased, the first magnet block continuously moves downwards, the first magnet block drives the sliding part to move downwards, so that the bottom of the baffle extends downwards, the baffle is lengthened downwards, the liquid channel between the bottom of the baffle and the concave part is gradually reduced, thereby make aluminium liquid constantly diminish from the speed that flows out in the liquid outlet, aluminium liquid is too big and empty in the outside of mould from the liquid outlet outflow speed when having avoided the mould to be full fast, has avoided flowing into the aluminium liquid speed in the mould too big and make aluminium liquid spill over, has also avoided the velocity of flow of aluminium liquid too big and arouse the great splashing of aluminium liquid in the mould, is convenient for empty aluminium liquid in the mould to filling with aluminium liquid.
Simultaneously, constantly pouring out along with the aluminium liquid in the soup ladle body, aluminium liquid in the soup ladle body constantly becomes fewly, and the liquid level of aluminium liquid is probably descended, and through this scheme, the bottom of baffle is extension downwards to can make the baffle be located below the liquid level of aluminium liquid, realized stopping the dross on the aluminium liquid that can descend to the liquid level.
Preferably, as an improvement, fixedly connected with head rod in the sliding part, fixedly connected with bar frame on the head rod, the rotation axis passes bar frame, fixedly connected with second connecting rod on the bar frame, first magnet piece is fixed to be located on the second connecting rod. Thereby, the connection of the first magnet block and the sliding portion is realized by the first connecting rod, the bar frame, and the second connecting rod. The sliding part is when vertical removal, and the bar frame is vertical removal as well, and the rotation axis relative movement in the bar frame, the bar frame can not offset with the rotation axis, and the rotation axis can not obstruct the vertical removal of sliding part like this for the baffle can normally stretch out and draw back.
