Abstract
The utility model discloses a double-head casting machine and belongs to the field of casting machines. The double-head casting machine comprises a power carrier roller, a die and oxhorn-shaped hoppers, wherein the die is placed on the power carrier roller; and feeding ports are arranged on two end walls of the die. The double-head casting machine is characterized in that: the oxhorn-shaped hoppers are respectively arranged on the feeding ports at the two ends of the die; and casting ladles are arranged above the oxhorn-shaped hoppers. By the adoption of the double-head casting machine, materials can be poured into the die through the two ends of the die at the same time, slurry is mixed in the middle of the die, and centrifugal casting is finished under the rotating centrifugal force of the die, so the temperature gradient caused by that the slurry flows from one end of the die to the other end of the die when one-head casting is reduced and the surface hardness of the roller body is balanced; and the thermal stress is constant and the bonding strength of the hard surface layer and the inner layer of the roller body is uniform, so that the forming quality of the roller body is improved.
Description
Technical field
The utility model belongs to the casting machine field, is specifically related to a kind of double end casting machine.
Background technology
In the production process of roll roll body, be to strengthen the packing of roll body, adopt the spun casting technology usually, spun casting is divided into two kinds of vertical centrifugal casting and horizontal type centrifugal-castings.Horizontal type centrifugal-casting be mould around horizontal rotational shaft, mainly be used for cover class and the tubing foundry goods of production length greater than diameter.Present horizontal type centrifugal-casting adopts a casting mode, is about to mould and is placed on the power carrying roller, and the power carrying roller drives the mould rotation, from the casting material such as end injection molten steel of mould, cast molding under the centrifugal action of mould rotation.This kind casting mode is simple to operate, is prone to row, in foundry industry, is extensively adopted, but along with the development of various process technologies such as food, and the demand of longer roll body is begun to sprout existing and increases gradually.
In the process that reality is used; It is inhomogeneous find to adopt the longer roll body of a casting mode moulding case hardness to occur, the wire drawing phenomenon in process such as food, occurs, causes the food that processes etc. of poor quality; Influence product qualified rate; Even the bond strength of the hard top layer of roll body and internal layer cast iron layer is not enough, causes roll body to damage and can not normally use, and become one of challenge that horizontal centrifugal pouring already faces.
Summary of the invention
The utility model technical problem to be solved provides a kind of double end casting machine, can realize the double end casting to longer roll body, has improved the Forming Quality of roll body.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of double end casting machine is provided; Comprise power carrying roller, mould and ox horn hopper, mould is placed on the power carrying roller, all offers the material mouth on the end walls of mould; It is characterized in that: on the material mouth of both mold ends the ox horn hopper is installed respectively, the top of ox horn hopper all is provided with casting ladle.
Preferably, also comprise scooter, the ox horn hopper is installed at the top of scooter.
Preferably, also comprise elevating lever, elevating lever is packed in the scooter, and the top of elevating lever connects the ox horn hopper.
The beneficial effect of the utility model is:
1, owing on the material mouth of both mold ends the ox horn hopper is installed respectively, the top of ox horn hopper all is provided with casting ladle, has realized the two ends material feeding in it simultaneously through mould; Slip mixes at the middle part of mould; Under the rotary centrifugal force of mould, accomplish spun casting, when having reduced a casting, slurry flows to the formed thermograde of the other end from an end of mould; Make the case hardness of roll body balanced; Because thermal stress is constant, makes the hard top layer of roll body and internal layer bond strength even, thereby improved the Forming Quality of roll body simultaneously.
2, owing to be employed in the mode that the ox horn hopper is installed at the top of scooter, make the mobile convenient, quick of ox horn hopper, saved human and material resources, improved efficient.
3, owing to comprise that elevating lever, elevating lever are packed in the scooter, the top of elevating lever connects the ox horn hopper, is convenient to regulate the height of ox horn hopper with respect to different moulds, has avoided the ox horn hopper to be exclusively used in the drawback of certain mould.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark among the figure: 1, power carrying roller; 2, mould; 3, ox horn hopper; 4, ox horn hopper; 5, scooter; 6, elevating lever; 7, material mouth; 8, material mouth; 9, casting ladle.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
As shown in Figure 1, in the utility model mould 2 is placed on the power carrying roller 1, offer material mouth 7 on the end wall of mould 2; Offer material mouth 8 on another end wall, on the material mouth 7 ox horn hopper 3 is installed, on the material mouth 8 ox horn hopper 4 is installed; The top of ox horn hopper 3,4 all is provided with casting ladle 9, has realized the two ends material feeding in it simultaneously through mould 2, and slip mixes at the middle part of mould 2; When having reduced a casting, slurry flows to the formed thermograde of the other end from an end of mould 2, makes the case hardness of roll body balanced; Because thermal stress is constant, makes the hard top layer of roll body and internal layer bond strength even, thereby improved the Forming Quality of roll body simultaneously.Ox horn hopper 3,4 is installed respectively on the scooter 5, makes the mobile convenient, quick of ox horn hopper 3,4.Be fixed with elevating lever 6 in the scooter 5, the top of elevating lever 6 connects ox horn hopper 3,4, is convenient to regulate ox horn hopper 3,4 height with respect to different moulds 2, makes same ox horn hopper 3,4 can be applicable to different moulds.
During use, mould 2 rotates under the effect of power carrying roller 1, and casting ladle 9 injects slip through ox horn hopper 3,4 respectively simultaneously in mould 2; Slurry is thrown toward its sidewall under the rotation centrifugal force of mould 2; Mobile to the other end separately simultaneously, the slurry at two ends mixes at the middle part of mould 2, after the top layer slip has been cast; The internal layer slip of casting once more is until the roll body moulding.This kind casting mode has reduced slurry in the axial flow process of rotation, has reduced the temperature difference, has realized that the axial temperature of roll body is even, has guaranteed that the adhesion of roll body ectonexine is even, has improved the Forming Quality of roll body.
It is to be noted; Above-mentioned embodiment only is the utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection domain of the utility model.
