Abstract
The utility model relates to a mould is cut to disposable essence of step motor gear realizes going on once only smart cutting the operation and having solved the tradition mould is unable realizes disposable smart problem of cutting the operation to the gear of rough cutting excircle, surely operates through disposable essence and has solved the unqualified problem of substep finishing tooth wheel product precision among the prior art effectively.
Description
Technical field
The application is related to a kind of gear die field, and in particular to a kind of high efficiency production stepping motor gear it is disposable
Fine cut mould.
Background technology
In the production process of precision mechanical part, traditional gear die expects thickness 0.5mm and material for there is thickness of thin
For rustless steel, the production of low voltage switch class stepping motor gear is particularly suitable for, because the dimensional accuracy to product will
Ask very high, existing mould be point four arcses substep fine cut into an annulus, all can produce because mould often runs a step
Error, and how accumulative the step number of operation error more be bigger, along with product material is rustless steel, the hardness of material is higher,
Each step has drawing material and moves when being punched, from further increasing error（Material gravitation discharges）, therefore, existing mould production
The concentricity of 18 sections of circular arcs of the stepping motor gear product for going out and 36 10 ° of angles are difficult to keep stable, it is impossible to produce and meet
The product of required precision.Therefore, by the structure of the existing mould of change, the product for meeting required precision can be stably produced.
The purpose of the application is to provide a kind of stepping motor gear disposable fine cut mould, cylindrical by first slightly cutting, and is allowed
Most is discharged in advance in gravitation in material, it is then cylindrical with a disposable fine cut of fine cut mould with whole drift（Not yet
There are cumulative errors）, it is achieved thereby that the concentricity of 18 sections of circular arcs and 36 10 ° of angles can stablize in product drawing requirement on product
The margin of tolerance in, the product for meeting required precision can be stably produced.
Utility model content
The purpose of this utility model is to provide a kind of stepping motor gear disposable fine cut mould, including fine cut drift
（1）, material returned block（2）, material returned block fixed block（3）, material returned spring（4）, punch fixing plate（5）, fixed plate backing plate（6）And screw
（7）, it is characterised in that the fine cut drift passes through screw（7）It is fixed on punch fixing plate（5）, material returned block（2）It is arranged on fine cut
Drift inside and can move up and down, material returned block further pass through screw（7）It is fixed on material returned block fixed block（3）On, it is described to move back
Material block fixed block upper end width is more than lower end width, and material returned block fixed block passes through and be fixed on fixed plate backing plate（6）, the material returned
Fixed block（3）Upper end and material returned spring（4）It is connected.
The fine cut punch shape is configured according to the shape of gear, and the material returned block and fine cut drift are run to same
The cylindrical structure of gear is constituted during plane.
The material returned block（2）By material returned spring（4）Realize moving up and down.
The gear is stepping motor gear, with 18 sections of circular arcs in same concentricity and 36 10 ° of angles.
Beneficial effect：Compared with prior art, the beneficial effects of the utility model are：By the one of stepping motor gear
Secondary property fine cut mould, realize to slightly cut cylindrical gear carry out disposable fine cut operation solved mould traditional cannot be real
Now the problem of disposable fine cut operation, by disposable fine cut operation substep fine cut product essence in prior art is efficiently solved
Spend underproof problem.

Specific embodiment
Fine cut drift 1 is fixed on punch fixing plate 5 by screw 7, material returned block 2 be arranged on fine cut drift inside and can more than
Lower motion, material returned block is further fixed on material returned block fixed block 3 by screw 7, and the material returned block fixed block upper end width is big
In lower end width, material returned block fixed block passes through and is fixed on fixed plate backing plate 6, upper end and the material returned bullet of the material returned fixed block 3
Spring 4 is connected, and when mould runs downwards, material returned block is first pushed down and slightly cuts cylindrical gear material, is conducted by the spring on material returned block
The power got off, fine cut drift realizes that to the waste material fine cut on gear now, material returned block pushes down tooth when mould runs to closure state
The strength of wheel is maximum, and mould starts to run up, and fine cut drift starts to run up with punch press, due to fine cut drift and gear
Material overlaps, and relative material is to be subject to very big resistance upwards, the thrust that material returned block is subject to upper diaphragm flexures downward to start fortune downwards
OK, when downward thrust is more than the resistance upwards that material is subject to, fine cut drift smoothly separates with gear material, due to material
It is compacted, deformation of products amount will very little, hardly affect the size of product, mould continues to run until that folding condition is so rushed
Bed just completes blanking process.
