Description
(1), technical field
The invention belongs to a kind of DN400-800 water-cooled metal mould centrifugal tube casting machine.
(2), background technology
There is following defective in the DN400-700 centrifuge that uses at present:
1, the cooling effect difference causes product quality problem and production efficiency low.The cooling system of water-cooled centrifugal tube casting machine is most important, is directly connected to product quality.At first require cooling evenly, if inhomogeneous, the excessive temperature differentials of cast tube if the thermal stress that body produced is inconsistent, will cause the fire check of body.Next requires enough cooling water inflows, and the water yield causes the cast tube cooling velocity to slow down will being directly connected to production efficiency inadequately.The DN400-700 centrifuge adopts the cooling tube mode of evenly arranging, but because cast tube female end diameter is big, complex structure, wall unevenness is even, and its heat dissipation capacity is very big, adopts this type of cooling often to cause the female end cooling very slow, there are the temperature difference in body and bellmouth, cause cast tube quality problems to occur, when producing the DN700 cast tube, this situation is apparent in view.In addition, requiring under the high efficiency situation, design of Cooling System causes water shortage to become very big restriction condition.
2, go up two actions of core apparatus (core frame swing and flexible) and finish by two oil cylinders, control respectively, the action accuracy rate is low.Core apparatus is made up of rotating mechanism, hold-down mechanism and core supporting device three parts on the DN400-700 centrifuge.Rotating mechanism is realized the rotation and the location of bell socket sand core by rotational fuel tank.Hold-down mechanism is to realize the mechanism that bellmouth core and pipe die compress by telescopic oil cylinder.In actual mechanical process, the core frame need be finished simultaneously and rotate and flexible two actions, and two mechanisms realize working alone and avoid interfering with each other separately by Trolley case.This cover mechanism complexity, owing to finish by intermediary agency's (Trolley case), so the requirement on machining accuracy strictness, working service is also had relatively high expectations, otherwise because cumulative errors (processing and wearing and tearing) will cause operation precision to reduce, influence is produced.
3, production cast tube specification is few, and the equipment scope of application is narrow.DN400-700 centrifuge maximum can be produced the DN700 cast tube, in use since equipment cooling, on system design problem such as core, it is more serious to produce DN700 cast tube quality problems, therefore can only produce the cast tube of DN400, DN500, three kinds of specifications of DN600 usually, reduce the use ability of equipment greatly.
(3), summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of water-cooled metal mould centrifugal tube casting machine, it is the cooling system good cooling results not only, two actions of last core apparatus are error free, expanded production specification, made lower limit can produce the cast tube of DN400, the upper limit can be produced the DN800 cast tube, and the cast tube quality improves greatly, and product percent of pass is more than 95%.
The present invention solves the technical scheme that its technical problem takes: it comprises centrifugal main frame, described centrifugal main frame comprises head, pipe die, riding wheel apparatus, last core apparatus, cooling water system, head is the fixing and actuating unit of pipe die, the female end external cylindrical surface of pipe die and end face are respectively near locking ring and retaining ring are arranged, retaining ring is fixed on the locking ring, the locking ring is fixed with support ring, stationary power input belt pulley on the support ring, support ring by bearing fixing in fixed disk, fixed disk is fixed on the support, other position of pipe die is supported by riding wheel apparatus, and riding wheel apparatus is fixed on the support; Last core apparatus comprises combined oil cylinder, core frame, hold-down mechanism, pivoted arm frame, one end of pivoted arm frame and the output shaft of combined oil cylinder are fixed, the other end mechanism that is fixed and clamped, fixed core frame on the hold-down mechanism, fixing bellmouth core on the core frame, described combined oil cylinder is fixed on the support, and combined oil cylinder links together telescopic oil cylinder and swing tooth bar oil cylinder, and, realize swing and flexible two actions by the feather key connection; Cooling water system comprises inlet channel, water jacket, outlet conduit, return flume, and inlet channel and outlet conduit are communicated with water jacket, and water jacket wraps in outside the described pipe die, on the support of outlet conduit outlet below return flume is arranged, and realizes not having pushing back water.
The internal diameter size of described locking ring has two kinds, the small-bore be used for producing the DN400-DN500 cast tube, wide-aperturely be used for producing the DN600-DN800 cast tube.
Described cooling water system segmentation is provided with, and guarantees that cooling evenly.
The inlet channel of described cooling water system, outlet conduit overstriking make cooling water inflow fully enough.
Because head has two kinds of locking rings, so expanded production specification, makes lower limit can produce the cast tube of DN400, the upper limit can be produced the DN800 cast tube.Owing to when design DN800 centrifuge,, the cooling system segmentation is provided with according to each section cooling velocity difference, female end adopts tube-in-tube structure, stresses cooling, and the overstriking cooling pipe makes cooling water inflow fully enough, adopting does not simultaneously have the water form that pushes back, and accelerates the cooling water circulation, and cooling effect is obvious.Because two actions of last core apparatus (core frame swing and flexible) change the combined oil cylinder form into by two traditional oil cylinder control forms, the action error of having avoided intermediate link to cause has improved the accuracy rate of action.The cast tube quality improves greatly, and product percent of pass is more than 95%.
