Abstract
The invention discloses a technology and method for removing horizontal burrs of turbine generator stator iron core grain oriented silicon steel pieces. A locating mould is used for placing punched pieces neatly, an appropriate grinding tool is used for conducting deburring processing on punched fracture faces, and at last, the fallen burrs are cleaned up. According to the technology and method, the novel materials (grain oriented silicon steel pieces) can be applied to the motor industry, the problem that the special burrs cannot be removed by a common deburring machine is solved and the phenomenon that a motor iron core emits heat is avoided.
Description
Technical field: what the present invention relates to a kind of turbine generator stator core punching has an orientation silicon steel sheet underturner process.
Background technology: the thick non-orientation silicon steel sheet material punching out of 0.5mm is adopted in the turbine generator stator core punching since the dawn of human civilization always in the generating equipment, its internal organizational structure of this material is even, only produce the vertical burr along pressing direction after the material punch process, this burr just can be removed totally with the normal sands burr machine of taking.But in recent years in order to reduce electromagnetic consumable at the combustion turbo generator, all adopt the orientation silicon steel sheet material that has of 0.35mm thickness to come the punching out stator iron-core lamination in the air-cooled steam turbine generator, this material is because the particularity of its milling method is different through the burr and the non-oriented silicon steel sheet that produce after the punch process, the processing back also produces a kind of thread horizontal burr along rolling direction except producing vertical burr, this burr is thread tight the connection with punching, can't remove with common flash trimmer, if this burr is not exclusively removed clean (especially in the slot wedge) punching closed assembly and is become can cause between lamination behind the iron core and connect, electric machine iron core heating phenomenon, utilize positioning clamping fixture that punching is stacked neatly so develop a kind of process of removing this burr, adopt suitable milling tool to remove the generation of this burr phenomenon of avoiding that the motor feels hot.
Summary of the invention: the purpose of this invention is to provide the process that a kind of removal has the horizontal burr of orientation punching, to avoid the generation of electric machine iron core heating phenomenon behind the assurance punching closed assembly.Technical scheme of the present invention is:
(1) silicon steel sheet with rolling passes through the uncoiler uncoiling along rolling direction, and the band material is sent in the upper and lower cutting edge of punch die of punch press, opens pressing equipment and carries out punching out processing.
(2) punching after the punching out separates with waste material, punching is put into specify pallet.The intact punching plane of disruption of punching out this moment has formed the vertical burr along pressing direction, has also formed the thread horizontal burr that links to each other with punching in addition on the plane of disruption of rolling direction.
(3) punching being removed vertical burr handles: the punching that the size qualified products will be housed is transported to by the abrasive band flash trimmer of appointment, and the one side that punching is jagged is relative with the abrasive band, and piecemeal sending into removed vertical burr in the flash trimmer.
(4) will go the punching of vertical burr to pile up neatly by manually putting into positioning clamping fixture, brush horizontal burr in slot part and the slot wedge up and down with steel brush, with yoke portion and the inside diameter of sand paper or nylon bruss friction punching, remove horizontal burr.
(5) with all planes of disruption of banister brush cleaning punching, prevent that burr from sticking on the section of punching, the burr complete liquidation of being struck off is clean.
Technique effect:
1. the present invention has broken the history that electromechanics trade continues the non-oriented silicon steel sheet punching out stator iron-core lamination of use always, has realized having this new material of orientation silicon steel sheet in the application of generator industry.
2. solved the problem that has the thread horizontal burr that forms after the punching out of orientation silicon steel sheet can't remove with the abrasive band flash trimmer, adopt positioning clamping fixture that punching is stacked neatly, by the suitable milling tool of artificial use that the thread burr polishing of these levels is clean, it is clean to be attached to the deburred of punching section with banister brush at last.
3. adopt positioning clamping fixture that punching is stacked punching section all aligns all when neat, section presents flat state, at this moment can expose the defective of section, for example the section of punching presents a bright line vertically, mould defectiveness herein is described, need to check the die clearance or with in time multiple mouthful on mould, to improve the punching cross section quality.
4 the invention solves the difficult problem that electric machine stator irons such as gas turbine generator, 1,000,000 ultra supercritical steam turbine generators, air cooling 200,000 turbo generators, air cooling 350,000 turbo generators have the horizontal burr of orientation silicon steel sheet removal.
Embodiment:
1. punching out is finished the qualified stator punching of size and be transported to by the flash trimmer of abrasive band by pallet, the one side that punching is jagged is relative with the abrasive band, punching a slice a slice is sent into removed vertical burr in the flash trimmer.
2. will go the punching of vertical burr to pile up neatly by manually putting into positioning clamping fixture, be stacked to till the 300mm height, the section of punching at this moment forms high plane of 300mm by the wire of thin slice, at this moment brush horizontal burr in slot part and the slot wedge up and down with steel brush, with yoke portion and the inside diameter of sand paper or nylon bruss friction punching, remove horizontal burr.
3. with all planes of disruption of banister brush cleaning punching, prevent that burr from sticking on the section of punching, the burr complete liquidation of being struck off is clean.
Need with equipment and instrument:
● have the 500T program controlled punch press of automatic driven unwind function
● meet the punch die of drawing geomery
● the abrasive band flash trimmer
● remove horizontal burr positioning clamping fixture
● the steel brush of band handle
● sand paper, nylon bruss
● banister brush.
Claims (1)
1. a turbine generator stator core has the horizontal burr process of orientation silicon steel sheet removal, it is characterized in that: (1) passes through the uncoiler uncoiling with the silicon steel sheet of rolling along rolling direction, the band material is sent in the upper and lower cutting edge of punch die of punch press, opened pressing equipment and carry out punching out processing; (2) punching after the punching out separates with waste material, the appointment pallet is put in punching, the intact punching plane of disruption of punching out this moment has formed the vertical burr along pressing direction, has also formed the thread horizontal burr that links to each other with punching in addition on the plane of disruption of rolling direction; (3) punching being removed vertical burr handles: the punching that the size qualified products will be housed is transported to by the abrasive band flash trimmer of appointment, and the one side that punching is jagged is relative with the abrasive band, and piecemeal sending into removed vertical burr in the flash trimmer; (4) will go the punching of vertical burr to pile up neatly by manually putting into positioning clamping fixture, brush horizontal burr in slot part and the slot wedge up and down with steel brush, with yoke portion and the inside diameter of sand paper or nylon bruss friction punching, remove horizontal burr; (5) with all planes of disruption of banister brush cleaning punching, prevent that burr from sticking on the section of punching, the burr complete liquidation of being struck off is clean, and above-mentioned technology is turbine generator stator core the horizontal burr technology of orientation silicon steel sheet removal.
