Abstract
This patent belongs to field of motor manufacturing.For solving the technical problem that mould is complicated when carrying out the operation of open slot cage rotor cast aluminium, installation is difficult at present, the utility model provides a kind of open slot cage rotor punching can cancelling mould in cast aluminium, it comprises circular punching body, circular uniform some rotor on punching body, rotor top is provided with the rotor extended to punching body edge and closes up, and it is characterized in that: rotor closes up and extends between rotor outer circle outline line and punching excircle configuration line.This rotor punching structure rationally, manufacture easy, can omit the middle mould of cast-aluminum die, cast-aluminum die manufacture becomes more succinct, and the rotor obtained after cast aluminium is consistent with existing open slot cage rotor in feature and performance.
Description
Technical field
This patent belongs to field of motor manufacturing, relates to a kind of cage rotor punching, can cancel mould in cast aluminium during cast aluminium, and the rotor made does not increase rotor aluminum consumption, and feature and performance are equal to open slot cage rotor.
Background technology
Current cage rotor punching is divided into open slot and closed slot two kinds, the structure of open slot rotor punching is shown in shown in accompanying drawing 1 and accompanying drawing 2, it comprises circular punching body 1, at the edge of ring-type punching body 1, uniform some rotor 2, are provided with rotor and close up 21 between the edge of rotor 2 top and punching body 1.After cast aluminium completes, full aluminium liquid is cast in rotor 2 and rotor closing in 21, the rotor of cast aluminium is delivered to lathe and carries out turnery processing, rotor radius by the turning of punching excircle configuration line 11 to rotor outer circle outline line 12, the distance that rotor radius reduces is referred to as monolateral rotor airgap, and rotor closing in 21 is opened on rotor outer circle outline line 12.Closed slot punching is then closed up without rotor, and the top of rotor is positioned at rotor outer circle outline line 12 inside.Open slot cage rotor is when carrying out cast aluminium operation thus, and Cast Aluminum Dies is generally divided into patrix, middle mould, counterdie, and open slot cage rotor rotor closes up and 21 to block by the effect of middle mould, and when preventing cast aluminium, aluminium liquid spills.And closed slot rotor can cancel mould in cast aluminium when cast aluminium, but closing up without rotor due to cast-aluminum rotor, there is not aluminium sliver in rotor surface, so rotor conductor resistance is comparatively large, not as open slot cage rotor in performance.
Summary of the invention
For solving the technical problem that mould is complicated when carrying out the operation of open slot cage rotor cast aluminium, installation is difficult at present, the utility model provides a kind of open slot cage rotor punching can cancelling mould in cast aluminium.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of open slot cage rotor punching can cancelling mould in cast aluminium, it comprises circular punching body, circular uniform some rotor on punching body, rotor top is provided with the rotor extended to punching body edge and closes up, and it is characterized in that: rotor closes up and extends between rotor outer circle outline line and punching excircle configuration line.
The beneficial effects of the utility model are: rational in infrastructure, manufacture easy, and can omit the middle mould of cast-aluminum die, cast-aluminum die manufacture becomes more succinct, and the rotor obtained after cast aluminium is consistent with existing open slot cage rotor in feature and performance.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of prior art split shed groove rotor punching.
Accompanying drawing 2 is the enlarged diagram at I place in accompanying drawing 1.
Accompanying drawing 3 is the structural representation of rotor punching provided by the utility model.
Accompanying drawing 4 is the enlarged diagram at II place in accompanying drawing 3.
The rotor punching structure schematic diagram of accompanying drawing 5 for obtaining after adopting the rotor punching turning that provides of the utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in accompanying drawing 3 and accompanying drawing 4, a kind of open slot cage rotor punching can cancelling mould in cast aluminium, it comprises circular punching body 1, circular uniform some rotor 2 on punching body, rotor 2 top is provided with the rotor extended to punching body edge and closes up 21, and this rotor closing in 21 extends between rotor outer circle outline line 12 and punching excircle configuration line 11.
As shown in Figure 4, because rotor closing in 21 is not directly opened on punching excircle configuration line 11, therefore carry out cast aluminium operation time need not worry aluminium liquid can by rotor close up 21 flow out, there is no need to design special plugging part, mould in can directly omitting, cast aluminium operation is with the operation of closed slot cage rotor.After cast aluminium, the rotor of cast aluminium is delivered to lathe and carries out turning operation, as shown in Figure 5, after rotor turning, the outline line of rotor surface is accompanying drawing 3 and the rotor outer circle outline line 12 shown in accompanying drawing 4, now, rotor closing in 21 is opened on this outline line, and the rotor obtained is as consistent in open slot cage rotor of the prior art in feature and performance.
