Abstract
The utility model relates to an automatic end cover system for a horizontal centrifugal casting machine, which is composed of a rotating arm, end covers, a flange casing, a hollow shaft, bearings, and mould end covers. A plurality of groove-shaped cavities which are communicated with each other and surround the wall of the hollow shaft are arranged between the outer surface and the inner surface of the hollow shaft, inlets and outlets are arranged on the cavities for the input and output of cooling liquid, the rotating arm is connected with the hollow shaft, and the flange casing is connected with the mould end cover. During the casting, ordered flowing cooling liquid is input into the cavities in the hollow shaft, the radiant heat of the alloy liquid in the casting groove and the radiant heat of the outward high temperature flame ejected by the hollow shaft can be removed, the problem of the excessively heated axle can be radically solved, and the normal and safe running of a casting machine can be ensured.
Description
The utility model relates to the mould end cap automatic open-close system on a kind of horizontal centrifugal casting machine.
Existing horizontal centrifugal casting machine automatic end convering system is by turning arm, flange outer sleeve, and hollow shaft and bearing, and mould end cap composition, its turning arm is connected with flange outer sleeve, and the mould end cap is connected with hollow shaft.When casting, along with the rotation of mould, the end cap of mould then drives hollow shaft and is rotated with respect to flange outer sleeve by bearing.The casting groove that is fixed on the turning arm through connector passes the hollow shaft axis hole, makes cast gate be in the mold cavity position.The problem that exists is, when high temperature alloy liquid is injected by the casting groove, hollow shaft is produced heat radiation, particularly foundry goods outwards ejects thermal-flame from the hollow shaft axis hole hollow shaft is produced long heat radiation in forming process, this makes hollow shaft and bearing be in abominable hot environment, causes the burning of lubricating oil in the bearing, makes bearing enclose increase distortion, cause bearing working unusual, thereby have influence on normally carrying out of casting work.
The purpose of this utility model is to provide a kind of horizontal centrifugal casting machine automatic end convering system, and in casting cycle, its hollow shaft and bearing are in the state of being cooled, thereby overcomes the problems referred to above that prior art exists.
Implementation of the present utility model: only need improve to original hollow shaft, make it have following feature: to be to have several in the axial wall between the surfaces externally and internally of hollow shaft around groove shape cavity axial wall and that communicate with each other, one an import and an outlet for cooling fluid output for the cooling fluid input arranged on the groove shape cavity that is communicated with, cavity in giving the hollow shaft axial wall injects cooling fluid, it is orderly when mobile that cooling fluid is formed, then nearly all radiant heat is taken away, thereby made hollow shaft and bearing be in normal working environment by cooling fluid.
Adopt horizontal centrifugal casting machine of the present utility model, fundamentally solved the excessively heated axle problem of hollow shaft and bearing, guaranteed under the long situation of required casting time, the safety of casting machine, normal operation.
Fig. 1 is the front section view of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
Below in conjunction with drawings and Examples the utility model is further narrated.
According to Fig. 1 and Fig. 2, present embodiment is by turning arm (1), end cap (3), flange outer sleeve (4), hollow shaft (10) and bearing (11), and mould end cap (5) composition, and having adopted following connected mode: turning arm (1) is connected with hollow shaft (10), and flange outer sleeve (4) is connected with mould end cap (5).The advantage of this connected mode is, when casting, the mould end cap (5) that is rotating will drive flange outer sleeve (4) rotation, and owing to flange outer sleeve (4) matches with the outer ring of bearing (11), hollow shaft (10) cooperates with the inner ring of bearing (11), thereby at this moment hollow shaft (10) then remains static, this provides safety assurance for the mounting means that casting groove (9) stretches in the hollow shaft (10), can overcome the hollow shaft rotating band and give hollow shaft and the mutual unfavorable factor of casting groove.The cooling liquid inlet of hollow shaft (10) axial wall internal cavity is connected with cooling fluid input adapter (7), and corresponding cooling liquid outlet is connected with cooling fluid out splice going splice (8).Cooling fluid can adopt the water that is suitable for cooling off usefulness, wet goods liquid, and the lubricated of bearing (11) realized by lubricating oil pipe joint (2) input lubricating oil.
Claims (3)
1, a kind of automatic end convering system of horizontal centrifugal casting machine, by turning arm (1), end cap (3), flange outer sleeve (4), hollow shaft (10) and bearing (11), and mould end cap (5) composition, it is characterized in that: be to have several in the axial wall between hollow shaft (10) surfaces externally and internally, an import and an outlet that supplies cooling fluid to export for the cooling fluid input arranged on the groove shape cavity that is communicated with around groove shape cavity axial wall and that communicate with each other.
2, horizontal centrifugal casting machine automatic end convering system according to claim 1 is characterized in that: turning arm (1) is connected with hollow shaft (10), and flange outer sleeve (4) is connected with mould end cap (5).
3, horizontal centrifugal casting machine automatic end convering system according to claim 1 and 2, it is characterized in that: the import on the groove shape cavity in hollow shaft (10) axial wall is connected with coolant inlet pipe joint (7), and corresponding outlet is connected with cooling fluid discharge conection (8).
