Background technique
Silicon steel sheet is a kind of carbon containing extremely low silicon-iron soft magnetic alloy, is mainly used to make various transformers, motor and hair
The iron core of motor.The processing technology of silicon steel sheet is affected to silicon steel performance, such as cold-reduced silicon sheet adds in punching and bending
During work, mechanical stress and strain are generated, leads to magnetic deterioration, iron loss can increase, therefore after processed, generally carry out
Stress relief annealing, to eliminate mechanical stress and strain, the original magnetism of restorer.Currently used silicon steel sheet punching die
In punching press and blanking operation, silicon steel sheet discontinuity equalization or there are frictional force between blanking channel leads to answering for silicon steel sheet
Power dispersion, the edge for influencing annealing effect, especially silicon steel sheet can generate deformation, greatly affected silicon steel sheet using effect.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of silicon steel machining process and its stamping die, design is new
Grain husk, the silicon steel sheet stress after punching press is uniform, improves silicon steel tablet quality and using effect.
To realize the above-mentioned technical purpose, present invention employs following technical solutions:
A kind of silicon steel machining process, which is characterized in that including following procedure of processing:
Step (1), sorting and feeding: the band-like steel material for meeting default material, thickness requirement, the steel that will be chosen using garage are chosen
Material is promoted to synchronous machine, the input terminal of the output end connection stamping device of synchronous machine；
Step (2), punching press: punching press is carried out to the steel material for being transported to predeterminated position using silicon steel sheet punching die, by steel material punching press
At the silicon steel sheet with preset shape, the silicon steel sheet punching die is using the formed punch in several non-inclined faces to same steel material
Carry out porous punching press simultaneously, it is made after silicon steel sheet stack be added together output；
Step (3), neat piece: quality inspection is carried out to the silicon steel sheet of the output end of stamping device, qualified silicon steel sheet is examined to carry out neat piece
Processing, places the neat superposition of each silicon steel sheet；
Step (4), vanning, weighing: the silicon steel sheet after neat piece is fitted into inside and is covered in the carton of polybag, carton inner wall brush is anti-
Rust is oily, and whole weighing is carried out after carton edge sealing and is recorded.
The invention also discloses a kind of silicon steel sheet punching die in above-mentioned silicon steel machining process, feature exists
In: including upper die holder, formed punch and lower die holder, several formed punches are arranged in the bottom of the upper die holder, and lower die holder, which is equipped with, is being located at formed punch just
The silicon steel sheet blanking channel of lower section, the bottom end of formed punch are set as non-inclined face and parallel with the input end of silicon steel sheet blanking channel.
Preferably, the width of the blanking channel and formed punch are of same size.
Preferably, the side of the formed punch is arranged to smooth surface.
By adopting the above-described technical solution, the present invention has the following technical effect that novel design of the invention, after punching press
Silicon steel sheet stress it is uniform, improve silicon steel tablet quality and using effect.
Detailed description of the invention
Examples of the present invention will be described by way of reference to the accompanying drawings, in which:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification unless specifically stated can be equivalent or with similar purpose by other
Alternative features are replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics
?.
The present invention provides a kind of silicon steel machining process, including following procedure of processing:
Step (1), sorting and feeding: the band-like steel material for meeting default material, thickness requirement, the steel that will be chosen using garage are chosen
Material is promoted to synchronous machine, the input terminal of the output end connection stamping device of synchronous machine；
Step (2), punching press: punching press is carried out to the steel material for being transported to predeterminated position using silicon steel sheet punching die, by steel material punching press
At the silicon steel sheet with preset shape, the silicon steel sheet punching die is using the formed punch in several non-inclined faces to same steel material
Carry out porous punching press simultaneously, it is made after silicon steel sheet stack be added together output；
Step (3), neat piece: quality inspection is carried out to the silicon steel sheet of the output end of stamping device, qualified silicon steel sheet is examined to carry out neat piece
Processing, places the neat superposition of each silicon steel sheet；
Step (4), vanning, weighing: the silicon steel sheet after neat piece is fitted into inside and is covered in the carton of polybag, carton inner wall brush is anti-
Rust is oily, and whole weighing is carried out after carton edge sealing and is recorded.
It is as shown in Figure 1 a kind of silicon steel sheet punching die in above-mentioned silicon steel machining process, including upper die holder
1, several formed punches 2 are arranged in formed punch 2 and lower die holder 3, the bottom of upper die holder 1, and lower die holder 3 is equipped with the silicon steel being located at immediately below formed punch 2
Piece blanking channel 4, the bottom end of formed punch 2 are set as non-inclined face and, blanking channel 4 parallel with the input end of silicon steel sheet blanking channel 4
Width it is preferably of same size with formed punch 2.Formed punch bottom end in silicon steel sheet punching die of the invention is different from traditional formed punch
Bottom end is the inclined surface structure with certain angle, and is arranged to the planar structure in non-inclined face, and formed punch is to silicon steel sheet surface
Stamping press is uniform, and former horizontal direction is able to maintain after the whole punching press of silicon steel sheet and enters blanking channel, silicon steel sheet will not tilt, more
Be easy to through blanking channel, frictional force is reduced between silicon steel sheet and the inner wall of blanking channel, therefore stress distribution will not be destroyed,
The concentration annealing for being conducive to subsequent annealing process, obtains the silicon steel sheet of uniform quality.
In the present invention, the side of preferably formed punch 2 is arranged to smooth surface, and resistance is smaller in punching course, blanking channel 41
Width and silicon steel sheet it is of same size, multi-disc silicon steel sheet stack transmits after being added together, be superimposed it is more neat.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
