Description
Technical field
The utility model relates to motor, transformer core is produced tooling device, relates in particular to riveted closed assembly device in a kind of iron core mould.
Background technology
Iron core is one of strength member of the products such as motor, transformer, generally by the silicon steel sheet of the high and low loss of permeability, is made.The iron core of a product can form to hundreds of sheet silicon steel sheet by several, and the quality of iron core overlapping quality will be directly connected to the performance of product.Along with the development of technology, iron core overlapping technology by traditional manual reason sheet, develops into automatic laminating.It has eliminated the techniques such as artificial reason sheet, pressurization, rivet or screw attachment, argon arc welding, makes punching in a secondary mould, complete punching closed assembly, has greatly alleviated workman's labour intensity, has improved labor productivity.During the products such as automatic laminating technology has now been widely used in electric machine rotor iron core, transformer core are manufactured.As shown in Figure 3, the iron core automatic overlapping and assembling of prior art is to realize in a secondary Multi-task position progressive die, conventionally by twice punching press, is completed the closed assembly of punching.During stamping-out, first in billot upper punch, make projection, then carry out blanking, under the stamping press effect that the bottom of a rear punching projection moves downward at punch, buckle into the top of last punching projection, be about to punching and laminate.During iron core overlapping, the pressure on top is from punch, and lower support power is from the frictional force producing between the Sleeve around pipe end inwall below die and punching outer rim.The frictional force that this method is subject to due to punching acts on punching outer rim, punching discontinuity, this frictional force is larger again, cause blanking punching easily to produce distortion, and punching also can produce distortion in thrusting process, tightness between punching and punching is inadequate, causes iron core overlapping second-rate, and properties of product decline.Chinese patent Granted publication number: CN2012.09.26, Granted publication day: 202454435U, a kind of Multi joint iron core overlapping platform is disclosed, comprise core lamination stack clamping device and iron core overlapping platform, on iron core overlapping platform, left and right bilateral symmetry is installed the left and right two parts core lamination stack clamping device cooperatively interacting, and iron core overlapping platform consists of some supporting leg upper end welding steels.During this equipment iron core overlapping, need manual operation, inefficiency.
