Abstract
The utility model discloses a cast-aluminum rotor centrifugal-casting hollow type water injection fast-retracting dummy shaft. The key point of the technical scheme is that the cast-aluminum rotor centrifugal-casting hollow type water injection fast-retracting dummy shaft comprises a shaft body and rotor punching sheets, wherein each rotor punching sheet is provided with a shaft hole, the shaft body is arranged in the shaft hole, the shaft body and the shaft hole forms a seal fit, one end of the shaft body is provided with a water inlet, the other end of the shaft body is provided with a water outlet, an empty cavity is arranged in the shaft body, and the empty cavity is respectively communicated with the water inlet and the water outlet. By injecting cooling water in the shaft body, the radial volume of the shaft body become smaller according to the heat-expansion and cold-contraction principle, thus the shaft body can be easily separated from the rotor punching sheets.
Description
Technical field
The utility model relates to a kind of mould, and more particularly, it relates to a kind of cast-aluminum rotor spun casting hollow type water filling rewind down dummy shaft.
Background technology
Rotor has multi-disc punching to stack formation, in punching, annular array has several punching grooves, in the time that stacking, punching forms cast aluminium through hole, the punching of folding needs frame, on straight tube dummy shaft, cast aluminium through hole is carried out to spun casting, during due to casting, temperature is very high, straight tube dummy shaft and punching are heated and are bulged, after causing cast aluminium, punching is difficult to separate with straight tube dummy shaft, people need to knock straight tube dummy shaft punching is separated with straight tube dummy shaft, cause straight tube dummy shaft easily to damage, or treat that bulk temperature reduction separates punching again with straight tube dummy shaft, but because the straight tube dummy shaft exiting is also with certain temperature, need coolingly could again load onto punching completely, cause processing slowly, lose time, improve processing cost.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of cast-aluminum rotor spun casting hollow type water filling rewind down dummy shaft.
For achieving the above object, the utility model provides following technical scheme: a kind of cast-aluminum rotor spun casting hollow type water filling rewind down dummy shaft, comprise axis body, rotor punching, described rotor punching is provided with axis hole, and set axis body is positioned at axis hole, and described axis body and axis hole form and be sealed and matched, one end of described axis body is provided with water inlet, the other end of described axis body is provided with delivery port, in described axis body, is provided with cavity, and described cavity communicates with water inlet, delivery port respectively.
By adopting technique scheme, when after cast molding, rotor punching can block with axis body, then in water inlet, pass through cooling water, cooling water flows in cavity from water inlet, and then flows out through delivery port, in this process, axis body has been subject to certain cooling, according to principle of expanding with heat and contracting with cold, with respect to there being before certain dwindling, at this moment just there is certain space in the radially area of axis body between axis body and rotor punching, so just axis body can be taken out very easily, time saving and energy saving.
The utility model is further set to: described cavity is spiral helicine cavity.
By adopting technique scheme, increase the flow process of cooling water, make the cooling more thorough of axis body.
The utility model is further set to: described water inlet is provided with rubber stopper.
By adopting technique scheme, in not needing to note cooling water, clog water inlet with piston, prevent that some foreign matters and reptile from entering.
The utility model is further set to: one end that described axis body is provided with water inlet is provided with handle.
By adopting technique scheme, can axis body be taken out by handle.

Embodiment
Referring to figs. 1 through Fig. 2, the utility model cast-aluminum rotor spun casting hollow type water filling rewind down dummy shaft embodiment is described further.
A kind of cast-aluminum rotor spun casting hollow type water filling rewind down dummy shaft, comprise axis body 1, rotor punching 5, described rotor punching 5 is provided with axis hole 8, set axis body 1 is positioned at axis hole 8 and axis body 1 forms and is sealed and matched with axis hole 8, one end of described axis body 1 is provided with water inlet 3, the other end of described axis body 1 is provided with delivery port 7, described water inlet 3 places are provided with rubber stopper 2, in described axis body 1, be provided with spiral helicine cavity 6, described cavity 6 communicates with water inlet 3, delivery port 7 respectively, and one end that described axis body 1 is provided with water inlet 3 is provided with handle 4.
When after cast molding, rotor punching 5 can block with axis body 1, then in water inlet 3, pass through cooling water, cooling water flows in spiral helicine cavity 6 from water inlet 3, can carry out so cooling fully, then water flows out through delivery port 7 again, in this process, axis body 1 has been subject to certain cooling, according to principle of expanding with heat and contracting with cold, the radially area of axis body 1 is with respect to there being before certain dwindling, at this moment between axis body 1 and rotor punching 5, just there is certain space, so just can axis body 1 be taken out very easily by handle 4, time saving and energy saving, do not need cooling in, water inlet 3 use rubber stoppers 2 are clogged, prevent that some foreign material and reptile from entering in cavity 6.
