The guide channel composed of the upper guide wheel and the lower guide wheel is used to replace a guide nozzle or a guide fitting, which can prevent twist, pole blockage with small friction and good surface quality of the casting blank, is applicable for continuous casting and continuous rolling production of pole stock used for copper alloy, aluminum alloy electrical engineering.
Description
Technical field
The utility model relates to a kind of continuous casting and connects the rolling equipment of pricking production line, especially relates to and a kind ofly is used for the production of copper alloy, the aluminium alloy electrician leads bit architecture with the special-shaped steel mill import that production line is pricked by pole stock continuous casting company.
Background technology
Copper alloy, aluminium alloy electrician are generally trapezoidal base with the continuous-cast blank of pole stock, in the operation of rolling, be respectively trapezoidal, circular, oval, spherical triangle etc. in strand cross section, the rolling position of difference, except that circular all is special-shaped base, in order to guarantee rolling carrying out smoothly, just need be when the milling train charging lead bit architecture and strand is reversed control by import.
Bit architecture is led in existing import, usually form by the guide wheel group of paired setting, but guide wheel group is controlled bad to reversing of shaped blank, therefore on this basis, between introduction group and milling train, be provided with and fixedly lead mouth or defend plate, lead mouth and defend plate when longer, linearity should not guarantee, and and the friction between the base is big, influences the base surface quality, so the influence of rolled quality; Lead mouth and defend plate more in short-term, cause blocked shot again easily.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can prevent to reverse, bit architecture is led in the milling train import of blocked shot and the little special-shaped base that rubs.
The technical scheme that its technical problem that solves the utility model adopts is: bit architecture is led in the milling train import of special-shaped base, comprise the leading wheels that are fixed on the rolling-mill housing, be provided with between leading wheels and milling train by support and be fixed at least one upper block on the rolling-mill housing and at least one lower tumbler, the bus by upper block and lower tumbler surrounds and constitutes the bit port of leading that axis projection and strand transverse shape adapt.
The beneficial effects of the utility model are: the bit port of forming by upper block and lower tumbler of leading replaces leading mouth or guide and guard, when avoiding reversing, changes sliding friction into rolling friction, and it is little rub, should not blocked shot, and cc billet surface quality is good.
Description of drawings
Fig. 1 is that master of the present utility model looks and partly cuts open figure;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the cooperation schematic diagram of embodiment two upper blocks and lower tumbler;
Fig. 4 is the cooperation schematic diagram of embodiment three upper blocks and lower tumbler.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Bit architecture is led in the milling train import of special-shaped base of the present utility model, comprise the leading wheels that are fixed on the rolling-mill housing, between leading wheels and milling train, be provided with by support and be fixed at least one upper block 1 and at least one lower tumbler 2 on the rolling-mill housing, the bus by upper block 1 and lower tumbler 2 surround constitute that axis projection and strand transverse shape adapt lead bit port 3.
The bit port of forming by upper block 1 and lower tumbler 23 of leading replaces leading mouth or guide and guard, leading bit port 3 axis projections and strand transverse shape adapts and can effectively avoid the generation reversed, sliding friction simultaneously changes rolling friction into, it is little to rub, unsuitable blocked shot, cc billet surface quality is good, only need change corresponding upper block 1 and lower tumbler 2 at difform shaped blank and get final product.
Concrete, described support is the split type structure that is provided with cavity, and described upper block 1 and lower tumbler 2 are respectively arranged with one and be arranged in the cavity.Because upper block 1 will closely contact with each surface of base with lower tumbler 2, airtight relatively working environment, prevented that foreign matter from entering the surface that is attached to upper block 1 and lower tumbler 2, thereby influence the surface quality of base, a upper block 1 and a lower tumbler 2 are set respectively and adopt the support of split type structure then to guarantee the facility of installing.Certainly upper block 1 and lower tumbler 2 also can be provided with respectively a plurality of, upper block 1 and lower tumbler 2 can stagger mutually vertically setting, also can be symmetrical arranged up and down.Upper block 1 and lower tumbler 2 two ends are fixing by bearing 6 respectively.
Further, interface position is to the influence on base surface when preventing to adopt subdivision up and down, and as scratching etc., split type structure before and after above-mentioned support adopts comprises the fore-stock 4 and the after-poppet 5 that are respectively arranged with charging hole and discharge opening; Described after-poppet 5 is fixed on the fore-stock 4 and by fore-stock 4 and is fixed on the rolling-mill housing.At this moment, after-poppet 5 is between frame and fore-stock 4, and the fastening force that fore-stock 4 is fixed on the frame forces after-poppet 5 to be close to the frame surface, has strengthened the support of after-poppet 5, has simplified the fixing operation of support.
Charging for convenience, the charging hole of above-mentioned fore-stock 4 is bellmouth orifices 42.
In order to guarantee that upper block 1 and lower tumbler 2 structures and milling train to the heart, further strengthen the fixed effect of support, above-mentioned after-poppet 5 is consistent with the hole shape of milling train import near milling train one end shapes.After fixing, after-poppet 5 inserts in the hole of milling train import, when guaranteeing the heart, has further simplified fixing operation.
In order further to avoid reversing of base, hole shape fixed the lead mouth 7 consistent in being provided with, the described fixed end that mouth 7 is fixed on after-poppet 5 of leading except the close milling train in hole with the strand cross section; A described fixed end of leading close upper block 1 of mouth 7 endoporus and lower tumbler 2 is a horn mouth.The bell-mouthed setting made things convenient for fixed mouth 7 chargings of leading, the fixed mouth 7 of leading is very short simultaneously, it is little to rub, and its place ahead and upper block 1 are adjacent with lower tumbler 2, and rear and rolling mill roll are adjacent, blocked shot can not take place, play the effect of taking over from the past and setting a new course for the future simultaneously, the fixed existence of leading mouth 7 has remedied upper block 1 and lower tumbler 2 with the gap between the rolling mill roll, has prevented that the secondary of base from reversing, guaranteed to prevent the effect reversed, should change the corresponding fixed mouth 7 of leading at difform shaped blank.
Insert cooling water for convenience the base temperature is controlled, simplify the making of support simultaneously, be provided with packing ring 8 between above-mentioned fore-stock 4 and the rolling-mill housing, radially be provided with the cooling water interface 10 that is communicated with the support cavity along packing ring 8.
