Sheet-like element carries out heat treated, makes sheet-like element and sheet-like element adhered to one another, makes with regulation stacking number
Bonding laminated cores.
Background technology
Generally, superposition batten is carried out the laminated cores of sheet-like element obtained by stamping procedure and blank operation by with
Make the stator or rotor of motor or electromotor, the method for laminated cores is made widely known in the technical field of the invention.
Carried out for forming groove portion, teeth portion successively by the batten to being supplied to grading (progressive) die device
Deng punch process and punch press process being formed continuously individual sheets shape part, finally, be stamped by regulation number superposition profile
Individual sheets shape part and make sheet-like element set, so as to make motor laminated cores.
Such as the content disclosed in Korean Patent Laid 10-2005-0026882 grades, individual sheets shape part
Fixing method have following so-called embossing laminating method, i.e. form embossing in each individual sheets shape part
(embossing), when being laminated sheet-like element, in the way of embossing is compressed mutually sheet-like element is made to tie mutually
Close.
With emboss as above overlapped way making motor core in, because making to be formed at mother in the way of forcing to buckle into
The shape fastening of the spill jut and convex jut of material, thereby serves to the effect such as deceleration driven and produces iron loss and magnetic
The loss of flux density.Also, Existential Space coefficient is reduced, produces the problem of vibrating noise because of covibration.
As the bonded laminating method for solving the above problems, in Korean granted patent publication the 10-0119014th
The stacking adhering device of motor core is disclosed, the stacking adhering device of said motor core includes：Mould, by lower mold support；
