Description

Punching machine for core of disk-type electrical motor

The utility model relates to a kind of punching apparatus of processing disc type electric machine end face groove iron core.

Disc-type electric motor is a kind of axial field electric motor makes of novelty, it with relatively have unique advantage when the same electrical performance with power radial magnetic field induction motor, mainly show as simple in structure, axial dimension is short, volume is little, in light weight, noise is low, material is economized, therefore it is in construction hoisting machinery, centrifugal machine, water pump, machine tool feed system, and particularly aspects such as control automatically, robot and household electrical appliance have a wide range of applications and demand.Iron core in the disc-type electric motor is a critical component, and it is to dash volume by band material to form, and the back of reeling is radially forming straight trough (or helicla flute, skewed slot) simultaneously.(see Fig. 1, Fig. 2, Fig. 3) in order to satisfy this design feature of iron core, had the special-purpose punching apparatus of processing this iron core at present, it can make band material the limit trimming around in make and have the various line of rabbet joint (straight troughs, helicla flute, skewed slot) iron core, but iron core exists the error that can't eliminate in winding process, this is because existing special-purpose punching apparatus itself does not have due to these compensation of error structures of elimination on the one hand, also be the most basic on the other hand, be that existing special equipment has problems on the processing method of iron core, thereby directly caused the mismachining tolerance of iron core.Below the iron core machining method in the prior art is done the introduction and the analysis of summary.

Switzerland Micro-Electric AG company, their existing special-purpose Punching and rolling machines that adopts the production disc type electric machine iron core of computer control.The volume mode of dashing of this kind Punching and rolling machine is with the Mathematical Modeling of logatithmic spiral as the disc type electric machine iron core.Whole dashing licks journey (Fig. 4), with logatithmic spiral is its Mathematical Modeling, iron core is to be clipped in OA, the OC limit with the continuous equation graduation of workpiece mandrel, the silicon steel sheet band material of breaking through slotted eye is wound up on the mandrel, along with iron core diameter constantly enlarges, it is outwards mobile that OB is prolonged at its center, forms iron core so gradually.This towards the volume mode as long as guarantee that iron core edge and OA, OC are tangent, and OA, OC limit angle perseverance are ψ, promptly obtain the straight-line groove iron core of five equilibrium.This shortcoming towards the volume mode: key issue is that silicon steel sheet band material is to be that Mathematical Modeling is dashed volume with the logatithmic spiral, and as seen the actual iron core that is wound logatithmic spiral anything but exists certain error.

Laid-open U.S. Patents in May nineteen eighty-two (U.S.No.4,320,645) published a Louis Stanley by name Australian's invention be used for process disc type and dash special equipment around iron core, its basic structure is as shown in Figure 5.When iron core band material is reeled, girth between every circle all has an increment, the position that increment is provided is at Hou Yiquan and last circle overlap (promptly rising to part), so the groove and the distance between groove of band material have just had corresponding increment to compensate with the continuous increase of the iron core number of turns.Compensation in this as can be seen from Figure 5 equipment is moved to the left by punch die and provides, and the workpiece mandrel vertically descended by lever transmission when this compensation was moved by the every circle overlap joint of band material on workpiece mandrel superposition.By this compensation rate of lever transmission but the iron core inter-alveolar distance is compensated on the position of actual needs by the overlap joint superposition, and dash volume when initial drift position and workpiece mandrel winding position certain distance is arranged, this method can not accurately be located.In the lever driving-chain, there is not correction to add mechanism in addition again, so this equipment exists the error that can't eliminate in coiling iron core.

The purpose of this utility model is for a kind of punching apparatus of disc type electric machine iron core is provided on the one hand, and it can overcome error and shortcoming in the processing of prior art iron core effectively, guarantee iron core dash around precision; Contain on it and eliminate the compensation of error device.

The purpose of this utility model realizes in the following way:

Thereby the punching apparatus of the utility model processing iron core is to adorn motion and the processing request that a cover auxiliary equipment is finished the utility model processing disc type iron core on existing arbitrary suitable punch press.Described auxiliary equipment has three parts, and they are transfer case assembly, worktable frame assembly, band material tensioning support assembly.
