Description
Technical field
It the utility model is related to the anti-tripping waste structure of the big piece groove profile cavity plate of high-speed electric expreess locomotive iron core multi-station progressive die.
Background technology
Electric machine iron core multi-station progressive die has turned into production main flow, and increasing enterprise enjoys to bring using progressive die
High efficiency, high accuracy, the advantage such as low cost.The input of conventional single punch-die is gradually reduced for this.But product size is increasing,
Motor product stator groove profile quantity is also more and more, such as stator groove profile is changed into 64,72,84 grooves from original 24,36,48 grooves,
Continue obviously unreasonable using single piece stator trench structure, groove profile quantity is more, and the accumulated error between groove profile is bigger, actual
It is also bigger to the tension of groove profile die block in production process, often there is groove profile die block tightening force deficiency, groove profile
Cavity plate loosens, and potential safety hazard occurs in mould production.
To solve the problems, such as that groove profile cavity plate easily loosens, using big piece groove profile cavity die structure (groove profile quantity >=3 groove), subtract
Few piece quantity, and fixing screws are set at the corresponding big piece groove profile cavity plate back side, ensure the normal production of mould.Due to adopting
With big tile configuration, groove profile cavity plate can not process anti-tripping waste groove using tool master grinding machine, find have in punching
During jump-scrap, mould is pulled down from lathe, cutting edge of die carried out slightly blunt or to cavity plate inwall craft kerve.What when
Between jump-scrap operating personnel it is uncontrollable, influence production efficiency and product cost.
The content of the invention
The present invention will overcome the disadvantages mentioned above of prior art, there is provided a kind of anti-tripping waste structure of big piece groove profile cavity plate.
The anti-tripping waste structure of big piece groove profile cavity plate, big piece groove profile cavity plate 2 is made up of some pieces of pieces 6, on piece 6
Groove profile 61 the groove of quantity >=3, piece 6 fixed with cavity plate fixing screws 4, and big piece groove profile cavity plate 2 is in annular shape, big piece groove
The excircle of type cavity plate 2 is inserted by the banding of die block 3, the inner periphery of big piece groove profile cavity plate 2 by plug 1, big piece groove
Type cavity plate 2 is provided with rotation stop alignment pin 5, it is characterised in that：The both sides inner wall surface of each groove profile 61 opens up skewed slot 62；Continuous
Punching press in, flute profile waste material 7 forms salient point 71, when flute profile waste material 7 is constantly down extruded in groove profile 61, salient point at skewed slot 62
71 skid off the side wall that skewed slot 62 touches groove profile 61, and flute profile waste material 7 is stuck on big piece groove profile cavity plate 2.
Further, the incline direction for the skewed slot 62 that the both sides inner wall surface of each groove profile 61 opens up is opposite.
Further, each side inner walls surface of groove profile 61 is provided with two to four skewed slots 62,62 wide 0.1mm- of skewed slot
0.2mm, deep 0.03mm-0.04mm, 5 ° -12 ° of gradient.
The salient point that the utility model is formed using flute profile waste material at skewed slot blocks flute profile waste material, prevents from jumping thereon.Even
In continuous punching press, flute profile waste material is moved down in groove profile, and the side of flute profile waste material is successively met according to position relationship with skewed slot
And form salient point, remove skewed slot again.After salient point removes skewed slot, on the wall for the groove profile for being just stuck in cavity plate, flute profile waste material is prevented
Upper jump.
Preferably, the incline direction of the skewed slot both sides inner wall surface of groove profile opened up is arranged on the contrary, being capable of gutter
Posture of the shape waste material in groove profile is more steady, further reduces the probability of flute profile scraps-bounce.
The skewed slot of the both sides inner wall surface of each groove profile of big piece groove profile cavity plate is machined by slow wire feeding.
The beneficial effects of the utility model are：Solve the scraps-bounce problem of big piece groove profile cavity plate in high speed blanking,
It can prevent scraps-bounce from causing cutting edge of die to burst apart, the risk that die life reduces, reduce production cost.

Embodiment：
The utility model is further illustrated below in conjunction with the accompanying drawings.
The anti-tripping waste structure of big piece groove profile cavity plate, big piece groove profile cavity plate 2 is made up of some pieces of pieces 6, on piece
Groove profile 61 the groove of quantity >=3, piece 6 fixed with cavity plate fixing screws 4, and big piece groove profile cavity plate 2 is in annular shape, big piece groove
The excircle of type cavity plate 2 is inserted by the banding of die block 3, the inner periphery of big piece groove profile cavity plate 2 by plug 1, big piece groove
Type cavity plate 2 is provided with rotation stop alignment pin 5, and the both sides inner wall surface of each groove profile 61 opens up 0.1mm-0.2mm two to four wide, depth
0.03mm-0.04mm, 5 ° -12 ° of gradient skewed slot 62, the incline direction of the both sides inwall skewed slot 62 of groove profile 61 are opposite；Continuous
Punching press in, flute profile waste material 7 forms salient point 71, when flute profile waste material 7 is constantly down extruded in groove profile 61, salient point at skewed slot 62
71 skid off the straight wall that skewed slot 62 touches groove profile 61, and flute profile waste material 7 is stuck on big piece groove profile cavity plate 2.
The salient point that the utility model is formed using flute profile waste material at skewed slot blocks flute profile waste material, prevents from jumping thereon.Even
In continuous punching press, flute profile waste material is moved down in groove profile, and the side of flute profile waste material is successively met according to position relationship with skewed slot
And form salient point, remove skewed slot again.After salient point removes skewed slot, on the wall for the groove profile for being just stuck in cavity plate.So, flute profile waste material
After raw material separation, its side continuously produces snap-in force with the side wall of groove profile, and the snap-in force is with the position of flute profile waste material
Gradual increase is moved down, prevents flute profile scraps-bounce.
The incline direction for the skewed slot that the both sides inner wall surface of groove profile is opened up is arranged to exist on the contrary, can stablize flute profile waste material
Posture in groove profile is more steady, further reduces the probability of flute profile scraps-bounce.
Content described in this specification embodiment is only enumerating to the way of realization of inventive concept, protection of the invention
Scope is not construed as being only limitted to the concrete form that embodiment is stated, protection scope of the present invention is also and in art technology
Personnel according to present inventive concept it is conceivable that equivalent technologies mean.
