Description
Technical field
The present invention relates to each punching manufacture technical field of mold, especially motor stamping in a kind of magnetic core of electric motor of automobile to return
Revolving die has.
Background technology
The magnetic core of electric motor of automobile interfixed after being typically stacked with by multiple punchings to certain altitude and
Form, however it is most of when punching produces in the prior art, directly will be between drift and cavity plate using drift and cavity plate
Metallic plate on rush after next product fall directly into the container for accommodating punching after carry out manual sorting again, enter again after arrangement
Row multi-disc punching lamination, this mode improves cost of labor, and production efficiency and automaticity are relatively low, due also to one
Each part thickness of block metallic plate exists inconsistent so that each position of punching being punched down can also have variable thickness
Cause, such mode of production be easily caused each position on the magnetic core being stacked up occur thickness difference difference very it is big, so as to influence
The performance of motor directly results in the consequence that the motor of production can not use, so people produce one based on drawbacks described above
The appearance for accommodating punching is fallen into after carrying out indwelling and the regulation that rotates to an angle in the passage of mould after planting under sheet punching press
In device, but any device that multi-disc is stacked to punching progress locking positioning is not provided with the indwelling passage of mould, caused
Centrifugal force caused by rotation loosens between causing between multi-disc punching then produces dislocation, may also lead to after dislocation by multi-disc heap
Folded punching and the motor core that forms have that thickness difference is differed greatly and punching is easily pulled, the top surface and soffit plane of motor core
Spend relatively low, perpendicularity and dimensional accuracy, which also are difficult to reach manufacture, to be required, so that the motor for being stacked punching by multi-disc and being formed
Dynamic balancing poor effect when magnetic core rotates, have impact on the performance of motor.
The content of the invention
The invention aims to solve above-mentioned technology deficiency and design a kind of improving production efficiency, reduce by
The thickness of motor core that multi-disc stacks punching and formed is poor, and the better motor stamping of rotation dynamic balancing of motor core
Turn round mould.
Designed by the present invention motor stamping revolution mould, from top to bottom successively include movable stripper plate, die block,
Die shoe and die shoe backboard, be respectively equipped with die block, die shoe mutually corresponding to through hole, and two through hole split is formed
Installation passage, installation passage is built-in to be provided with revolving body, and the bottom of revolving body is socketed with the belt wheel that revolving body can be driven to rotate, revolution
Cavity plate is embedded with the top of body, and the forming cavity of cavity plate connects with the stamping parts indwelling passage of revolving body, the stamping parts of revolving body
Indwelling passage madial wall is embedded with clamp ring one and clamp ring two, and clamp ring one is adjacent to be located in the bottom of cavity plate, clamp ring two
The bottom of the stamping parts indwelling passage of revolving body；Inserted with top and the metallic plate that will be located at turn around at the top of body on stripper plate
On rush the drift of next stamping parts product, top can be contacted at the top of revolving body with driving rotary body to bottom offset；Die shoe
Spacing collar and stamping parts latch assembly are embedded with the inner passage of backboard, spacing collar is located at the top of die shoe plate, stamping parts
There is the stamping parts for being locked stamping parts to lock passage for the inside of latch assembly, be pushed up in the endoporus of spacing collar inserted with floating
Block, the endoporus top opening of spacing collar are provided with position limiting convex ring at, and the top peripheral side of floating jacking block is provided with limited ring groove, and spacing
Bulge loop is positioned in limited ring groove, and the top of floating jacking block contacts at the bottom of revolving body, floating jacking block after position limiting convex ring
Endoporus be placed on the top of stamping parts latch assembly, being contradicted between stamping parts latch assembly and the bottom of floating jacking block has for floating
Jacking block up spring, stamping parts locking passage can be located on same central shaft and mutually corresponding with stamping parts indwelling passage automatically
Connection, the top of stamping parts locking passage at the top of spacing collar all the time with being mutually flush, and stamping parts locking is logical after revolving body is up
The top in road forms Separation with the bottom of clamp ring two.
Punching angle of the said structure using belt wheel rotation regulation positioned at stamping parts locking channel bottom, it is sharp after regulation
Smoothly separated and be connected in punching course with the punching in clamp ring two with the punching of stamping parts locking passage, and turned round
After body rotation, the multi-disc punching in indwelling passage carries out locking positioning in the presence of clamp ring one and clamp ring two, from
And prevent revolving body from rotating and situation that multi-disc punching rotates under the influence of centrifugal force occurs, avoid between multi-disc punching
Misplace, at the same in the presence of the clamping and positioning of clamp ring one improve punching flatness effect, clamp ring two ensure rotation
The a piece of punching of stamping parts indwelling passage bottommost is not fallen down during turning, then by stamping parts latch assembly in revolving body
Last a piece of punching is changed to stamping parts locking passage during punching press and topmost realizes slitless connection and the mistake locked
Journey, stamping parts latch assembly cause revolving body move upwards after with being separated at the top of stamping parts locking passage when, in revolving body
Punching will not fall the phenomenon of piece, avoid punching and produce relative motion mutually in separation process, in turn result in product change
Shape and scuffing.
Further preferably, stamping parts latch assembly includes two pieces of stamping parts latch being symmetrically set, is fixed on punching
Locking bar on the inside of casting die latch, lock bar top insertion floating jacking block endoporus in, and lock bar top with it is spacing
It is mutually flush at the top of circle, the top of locking bar forms Separation with the bottom of clamp ring two after revolving body is up；Float and push up
The bottom of block is provided with slot, and the top of stamping parts latch is inserted in slot, and locating piece is protruding with the outside of stamping parts latch,
Spring is contacted between locating piece and floating jacking block, and passage is locked in the gap between two locking bars for stamping parts.Its is compact-sized
Reliably, be pointed to stamping parts locking passage in multi-disc punching lock, the performance of clamping and positioning more preferably, especially positioned at lock
Tight uppermost one flat punching of passage, when ensureing revolving body motion separating with locking bar upwards, punching in revolving body will not be by
In punching depart from clamp ring not exclusively, clinging etc. for hydraulic oil produce the phenomenon of piece in rotary course, avoid punching point
Produce relative motion mutually from during, in turn result in deformation of products and scuffing.
