Abstract
The utility model relates to a big-revolution special-shaped tightening structure of a motor iron core progressive die. The structure comprises a revolution tightening sleeve which is used for a non-circular special-shaped iron core, wherein the tightening sleeve has a similar copying shape of the non-circular special-shaped iron core; and cemented carbide tightening strips are embedded into the tightening sleeve. The revolution tightening structure is compact, can improve the cutting speed and can enlarge the scale of producing non-circular special-shaped iron cores by using big-revolution automatic stacked progressive dies, and the weight is greatly reduced.
Description
(1) technical field
The utility model relates to the diel of the big rotating automatic overlapping and assembling of a kind of electric machine iron core progressive die band.
(2) background technology
For eliminating of the influence of silicon steel sheet sheet thickness error to the electric machine iron core lamination thickness; The line that changes each punching in the electric machine iron core to; The method that solves generally is on the micron order progressive die in the electric machine iron core lamination process; 20 °～180 ° orientation angles of every rotation are folded a slice punching, and the rotation of this wide-angle laminates the influence to the iron core gauge of the thickness of slab error that can effectively eliminate behind the punching lamination, and the iron core gauge can reach required precision higher more than the IT8; The line of also having guaranteed each punching in the electric machine iron core is to staggered, thereby reaches the purpose that improves the motor product technical performance.
The technology that the wide-angle rotation of foregoing description laminates iron core is " a big revolution technology ", has been applied in the electric machine iron core automatic overlapping and assembling progressive die at present, is called as the big revolution automatic overlapping and assembling of electric machine iron core progressive die.This mould adopts servomotor, synchronous band, slew gear and Programmable Logic Controller, can stablize, realize reliably that punch press whenever just rotates 20 °～180 ° big revolute function towards the slew gear of a mould.
Because it is many that the big revolution automatic overlapping and assembling of electric machine iron core progressive die generally is used for the big revolution lamination of circular iron core; And the tightening structure in the slew gear in mould is coaxial circular configuration; Structurally realize than being easier to; Therefore, ask for something all adopts big revolution automatic overlapping and assembling progressive die to produce iron core than higher circular iron core.Along with the raising that the special-shaped iron core of some non-circles requires, the special-shaped iron core of increasing non-circle also adopts big revolution automatic overlapping and assembling progressive die to produce iron core.
Most important part in the big revolution automatic overlapping and assembling of the electric machine iron core progressive die slew gear is that cover is tightened up in revolution.For the special-shaped iron core of non-circle is tightened up; In cover is tightened up in revolution, inlayed a carbide alloy abnormity edge cover, because carbide alloy edge cover volume is bigger, the structure that takes up room is many; Cause that revolution tightens up that nested structure is huge, weight increases; Manufacturability is relatively poor, and cost is higher, adopts big revolution automatic overlapping and assembling progressive die to produce iron core for the special-shaped iron core of non-circle and brings very big difficulty.Simultaneously, machine rotating part weight increases, also cause moment of inertia too senior general directly influence the stamping-out speed of mould, mould stamping-out speed is obviously reduced.In addition, if not tungsten carbide button's abnormity edge cover is tightened up in the cover in revolution, revolution is tightened up cover because of being subjected to the restriction than carbide alloy difference of self material wear ability like this, makes to turn round to tighten up to overlap and significantly reduces service life.
(3) summary of the invention
The utility model will overcome the revolution of the existing big revolution automatic overlapping and assembling of electric machine iron core progressive die slew gear and tighten up the carbide alloy abnormity edge cover shortcoming that volume is excessive, difficulty of processing is big, cost is high that nested structure is huge, moment of inertia is big, used, provide a kind of structure light and handy compact, moment of inertia is little, be easy to process, the special-shaped tightening structure of big revolution of electric machine iron core progressive die that cost is low.
The special-shaped tightening structure of big revolution of the described electric machine iron core progressive die of the utility model; Comprise that the revolution that is used for the special-shaped iron core of non-circle tightens up cover; It is characterized in that: the described cover that tightens up has the similar profiling shape of the special-shaped iron core of non-circle, the described interior tungsten carbide button of the cover tightening that tightens up.
In the non-circular shaped core comprising a rotary tightening tightening of carbide inlay, inlaid with carbide rotary tightening kit compared casement profiled overall tightening of small size, the structure occupies less space, so that the tighten the cap structure is very compact swing.
The utility model is in cover is tightened up in revolution, directly to process and the special-shaped similar profiling shape of non-circle, tungsten carbide button's tightening again.The tightening of the prior art rotary carbide shaped mosaic inlay kit processing is to tighten the rotary machining a circular stepped bore kit, and then inlaid circular shape while the inner shape of the non-circular shaped carbide casement.
The beneficial effect of the utility model mainly shows: under the identical situation of the special-shaped core dimensions of non-circle, tighten up the interior tungsten carbide button of cover abnormity edge cover with revolution and compare, the nested structure compactness is tightened up in revolution, and weight declines to a great extent.It is the principal element that influences moment of inertia that cover weight is tightened up in revolution, and moment of inertia too senior general directly influences the stamping-out speed of mould, and mould stamping-out speed is obviously reduced.Revolution can improve stamping-out speed 20～30% after tightening up the nested structure change.In view of the above, the utility model will enlarge the specification that the special-shaped iron core of non-circle adopts big revolution automatic overlapping and assembling progressive die to produce iron core.

(5) embodiment
With reference to accompanying drawing:
The special-shaped tightening structure of big revolution of the described electric machine iron core progressive die of the utility model; Comprise the revolution that is used for the special-shaped iron core of non-circle tighten up the cover 1; The described cover 1 that tightens up has the similar profiling shape of the special-shaped iron core of non-circle, the described cover 1 interior tungsten carbide button tightening that tightens up.
Described carbide alloy tightening comprises first tightening 2 and second tightening 3 that is used for the plane that is used for the bight.Have shoulder 4 on described second tightening.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection range of the utility model only limits to the concrete form that embodiment states, the protection range of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
