Description
Technical field
The present invention relates to motor, transformer core production tooling device, relate 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.
Summary of the invention
The problem to be solved in the present invention is, for the defect of prior art, provides riveted back bracket closed assembly device in a kind of iron core mould, and the distortion in the time of reducing punching closed assembly, guarantees iron core overlapping quality, enhances product performance.
Object of the present invention is achieved through the following technical solutions.Riveted back bracket closed assembly device in iron core mould, comprise die, the downside of die is provided with die shoe, die shoe is provided with Sleeve around pipe end, in Sleeve around pipe end, be provided with iron core overlapping passage, the downside of die shoe is provided with the plate that connects material, die shoe downside and connect material and be provided with iron core slide aperture between plate, one side of iron core slide aperture is provided with iron core ejecting device, in the iron core overlapping passage of described Sleeve around pipe end, be provided with iron core pallet, the downside of iron core pallet is provided with a connecting rod, and the plate that connects material is provided with a through hole, and connecting rod is connected with a drive unit through the through hole connecting material on plate.This device compared with the difference of the iron core automatic overlapping and assembling device of prior art is, at the iron core overlapping passage of Sleeve around pipe end, set up iron core pallet, and iron core pallet is driven by drive unit.Drive unit promotes iron core pallet and rise to certain altitude in iron core overlapping passage, start punching press punching, when the quantity of punching meets the requirements of sheet and counts, drive unit drives iron core pallet to decline, the upper plane for the treatment of iron core pallet drops to the upper plane of the plate that connects material with high, and drive unit stops.Now, iron core ejecting device is started working, and iron core ejecting device promotes iron core, iron core is pushed away to the downside of iron core overlapping passage, outside launch mode.During iron core overlapping, the pressure on top is from punch, and lower support power from the frictional force producing between the Sleeve around pipe end inwall below die and punching outer rim, mainly comes from the support force of drive unit to iron core pallet on a small quantity.Because the frictional force of punching outer rim reduces, punching bottom is subject to the support force of iron core pallet, make the whole bottom of punching stressed evenly, and punching top is also that stepless action is in punching from the pressure of punch, punching top and bottom are stressed evenly, therefore punching is not yielding in closed assembly process, and the distortion that punching produces in thrusting process is also corrected, the distortion of punching diminishes, tightness between punching and punching also increases, iron core overlapping quality has obtained large increase, and properties of product are also greatly improved.
