Abstract
The utility model discloses a cast-aluminum rotor punching, which comprises a punching body, wherein a rotating shaft hole is formed in the central position of the punching body, a key slot is formed on the rotating shaft hole, and 84 grooves are formed on the radial surface of the punching body adjacent to the periphery respectively; each groove adopts a closed groove structure, and the distance from a groove-shaped outer groove to the periphery of the punching body ranges from 1.0 mm to 1.2 mm. The grooves of the cast-aluminum rotor punching adopt the closed groove structures, the closed part serves as the middle mold of the cast-aluminum mold during the aluminum casting process of the rotor, so as to prevent the molten aluminum from overflowing, and various required lengths of the iron core are conveniently processed, so that the cast-aluminum rotor punching has a simple structure and is easy for implementation; and furthermore, the middle mold of the cast-aluminum mold is saved, and the production cost, the production period and the management cost are all reduced.
Description
Technical field
The utility model relates to a kind of cast-aluminum rotor punching.
Background technology
At present, traditional cast-aluminum rotor punching flute profile is the open slot structure, corresponding cast-aluminum die will comprise patrix, middle mould, counterdie and mandrel usually, because same seat No. is divided into several specifications, and core length is also inequality, and this just needs mould in several covers of corresponding outfit, has the production cost height, production cycle is long, the shortcoming of production management inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of cast-aluminum rotor punching, and it has simple in structure, saves cost, characteristics with short production cycle.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of cast-aluminum rotor punching, it comprises punching body, shaft hole, keyway and is opened in several flute profiles of punching body limit sagittal plane, wherein, described flute profile adopts the groove structure of remaining silent, and the distance of the outer slot pitch punching body periphery of described flute profile is than the little 0.2mm～0.4mm of gas length.
Especially, the distance of the outer slot pitch punching body periphery of described flute profile is 1.0mm～1.2mm.
Especially, offer 84 flute profiles on the described punching body.
The beneficial effects of the utility model are, the flute profile of described cast-aluminum rotor punching adopts the groove structure of remaining silent, closing section is equivalent to mould in the Cast Aluminum Dies during casting aluminum rotor, stops molten aluminium to overflow, the various required core lengths of convenient processing, during rotor processing external diameter, the flute profile part of remaining silent is fallen in turning, and notch exposes, and meets design requirement, not only simple in structure, be easy to realize; And saved mould in the Cast Aluminum Dies, reduce production costs, production cycle and management cost.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the utility model cast-aluminum rotor punching;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure:
1, punching body; 2, shaft hole; 3, keyway; 4, flute profile; 5, flute profile water jacket; 6, punching body periphery.
Embodiment
Please refer to Figure 1 and Figure 2, Fig. 1 is the structural representation of the utility model cast-aluminum rotor punching; Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
In present embodiment, a kind of cast-aluminum rotor punching, it center that comprises punching body 1, described punching body 1 offers shaft hole 2, offer keyway 3 on the described shaft hole 2, and offer 84 flute profiles 4 on the sagittal plane of described punching body 1 near periphery, described flute profile 4 adopts the groove structure of remaining silent, and described flute profile water jacket 5 apart from the distance of punching body periphery 6 than the little 0.2mm～0.4mm of gas length, described gas length H is 1.4mm, and then described flute profile water jacket 5 is 1.0mm～1.2mm apart from the distance of punching body periphery 6.
The flute profile of above-mentioned cast-aluminum rotor punching adopts the groove structure of remaining silent, closing section is equivalent to mould in the Cast Aluminum Dies during casting aluminum rotor, stop molten aluminium to overflow, the various required core lengths of convenient processing, during rotor processing external diameter, the flute profile part of remaining silent is fallen in turning, notch exposes, meet design requirement, not only simple in structure, be easy to realize; And saved mould in the Cast Aluminum Dies, reduce production costs, production cycle and management cost.
