Description
The utility model relates to the cast tube machine of the centrifugal production of a kind of water cooling metal mold 400-700mm ductile iron pipe.
Centrifugal ductile cast iron pipes has high strength, deep drawing quality, advantages such as good corrosion resistance, extensively in city and industrial construction water supply gas transmission engineering, use, China does not also produce the equipment of 400-700mm ductile iron pipe, manufacturer mainly concentrates on industrially developed country, wherein German machine is good slightly on performance, it is mainly by pouring section, host machine part, the tube drawing part, take over part, compositions such as fortune tube portion, it mainly contains following shortcoming: 1) German spun cast pipe dust feeder adopts oil motor to drive feeding screw, its screw rod length reaches 7 meters, at work because the chute thermal deformation, the screw-casing rod bending, it is undesired to cause the pipe die powder to carry, sometimes also need workman's cloth powder, greatly reduce production efficiency; 2) the synchronous rotation of bellmouth core and pipe die guarantees by the contact force of stooling frame spring compression bell socket sand core and pipe die, so the bellmouth core is in stress, and the big slightly bellmouth core of thrust is frangible, and breakage rate reaches 3-5% sometimes; Thrust is slightly little, and bellmouth core and pipe die frictional force are not enough, and the bellmouth core phenomenon that " throws switch " takes place, and fuse and molten iron generation relative motion cause the bellmouth part of poor quality; 3) selection of the material plate of guide rail and wheel is unreasonable, uses less than 1 year, and guide rail spreading distortion reaches 5-10mm, and the wheel wearing and tearing are also more serious, and host center is moved down, and are excessive with tube pulling machine centre deviation, cause the tube pulling difficulty; 4) because unreasonable on the structural design between the complete machine various piece, every parts and each parts cooperate last non-cutting time all longer in action, and it is longer therefore to produce a cast tube time, and productivity ratio is lower.
The purpose of this utility model is to design a kind of production efficiency height, and the pipe die powder is carried convenient and swift, the not breakable centrifugal tube casting machine of bellmouth core.
The utility model be achieved in that it by apparatus for pouring, host machine part, tube pulling machine, take over part, base, electric part and hydraulic part and form, wherein, apparatus for pouring is fixed on an end of base, fan-shaped casting ladle is arranged on it, water and wrap the fixed constant velocity plate, elevating ram is by the pulley mechanism of cranking arm, drive the constant speed plate and provide uniform iron water amount to chute so that casting ladle is left and right, the front end of apparatus for pouring is left and right chute, left and right chute can left and rightly move under the driving of hydraulic cylinder, and can turn over turnback, carry out continuously to guarantee cast.Host machine part has a hollow cylinder, and it is fixing vehicle wheel down, is sitting in by wheel on the track of base, and make it can prolong track by hydraulic cylinder and move forward and backward, promptly away from apparatus for pouring, or near apparatus for pouring; Be fixed with motor, water inlet pipe and water outlet pipe and cable on it; It in it cast tube mould by the support roller supporting, the high speed rotation of cast tube mould is that motor drives by belt, the Inlet and outlet water cooling tube is arranged on the cylindrical cavity outside the cast tube mould, guarantee that in the centrifugal casting process molten iron institute liberated heat water that all is cooled takes away, to obtain high-quality cast tube; Also be fixed with a bellmouth core manipulator on away from the cylinder of apparatus for pouring one side, this manipulator, can also be moved forward and backward outside the decapacitation rotation by Driven by Hydraulic Cylinder.Drawbench is fixed on the opposite side of base, and the master cylinder on it can make the tube drawing pincers stretch out, and leading oil cylinder can make the strong spreading of jaw, and to clamp cast tube female end straight tube inwall, when treating that main frame retreats, cast tube is extracted automatically.Taking over part is made up of bulb-tubulating machine, adapter dolly and adapter trolley track, two independently support arms are arranged on the bulb-tubulating machine, this support arm is on base rail, under the pipe die base and with guide rail in vertical state, two support arms can be swung 90 degree, and can automatically reset, and its front end can lift, so that the good pipe of casting tumbles automatically to taking on the dolly.Take over dolly and taking on the trolley track by pressure wheel, taking on the dolly has electronic scale, and display tube is heavy automatically, drives by the capstan steel wire rope, in order to cast tube is transported on the tempering furnace track.
Fix a powder feeding pipe at left and right chute outer bottom, powder feeding pipe links to each other with high-pressure air pipe.
Change the shaft section of stooling frame on the bellmouth core manipulator into " L " type, allow stooling frame and pipe die inner face press, and consequent frictional force drive core rotates synchronously.
The utility model compared with prior art has following advantage: 1) owing to reasonable in design between each several part, action cooperates non-cutting time short, thereby has improved productivity ratio; 2) owing to adopt the automatic cloth powder of aerodynamic force, shortened the time of cloth powder greatly; 3) because core does not directly contact with pipe die, greatly reduce the breakage rate of core, thereby improved the qualification rate of cast tube.
