Description
Technical field
The present invention relates to a kind of process using holotype high accuracy positioning laser cutting generator thin plate fanning strip.
Background technology
Laser cutting plate is that the Operational preparation cycle is short compared to forcing press punching processing plate advantage, small lot processing
When the cycle is short, cost is low, more flexible, and due to laser cutting when need high pressure auxiliary gas shield, it is combustion-supporting and remove slag,
When processing generator thin plate fanning strip, when particularly sheet metal thickness is between 0.5mm-1mm, high pressure auxiliary gas blows laser and cuts
Processing notch to be cut, causes defocusing amount constantly to change, the surface quality of section is poor, while produces horizontal wavy cutting track, into
And cause dimension overproof.
The content of the invention

Cursor position uses for making when internal layer supporting plate (4), outer layer supporting plate (5)；
2) tool part blanking is positioned：Special point grid (1), connector (2), retainingf key (3), internal layer supporting plate (4), outer layer support
Plate (5) is cut by laser blanking according to coordinate position：Special point grid (1), connector (2), retainingf key (3) internal layer supporting plate (4) and outer
The material of layer supporting plate (5) is Q345 steel plates, and hydraulic press flattens after internal layer supporting plate (4), outer layer supporting plate (5) blanking, special after blanking
It is not cusp defect that tool marks, which are inscribed, in sharp grid (1), connector (2), retainingf key (3) hole, need to be polished at cusp with file, special point grid
(1), internal layer supporting plate (4), outer layer supporting plate (5) unevenness are less than or equal to 3mm, and special point grid (1) are internal layer supporting plate (4) and outer layer support
The branch stake tool of plate (5), its structure are:Be made of the Q345 steel plates of thick 3mm, holotype is made of upper and lower two parts, lower part be with
There is the pilot hole with the fastening of retainingf key (3) bolt in connector (2) matched circular portion, circle centre position, top is divided into support
The gusseted part of internal layer supporting plate (4) and outer layer supporting plate (5), top are down flat to firm support internal layer supporting plate (4) and outer layer
There is the fixing groove fixed with laser cutting machine in supporting plate (5), special point grid (1) both sides, top needs to be polished with file；
3) instrument assembling is positioned：Special sharp grid (1), connector (2) are used into bolt, gasket and nut with retainingf key (3)
Assembling, places internal layer supporting plate (4) and outer layer supporting plate (5), makes square hole and retainingf key on internal layer supporting plate (4) and outer layer supporting plate (5)
(3) protrusion coordinate, at internal layer supporting plate (4) and outer layer supporting plate (5) bottom cooperation increase solder joint be allowed to fixed, by it is square forever
Magnet is placed in supporting plate magnet bore (6), and in supporting plate magnet bore (6) bottom, increase solder joint consolidates the permanent magnet inside hole；
4) prepare and process before processing：Thin plate plate to be cut by laser is placed on outer layer supporting plate (5), it is ensured that covering
Reserved path and magnet hole site are processed, then starts Laser cutting thin plate punching；
5) restorer state after processing sheet punching：After product examination qualification, spiral shell is disassembled using Wrench
Bolt, gasket and nut assembling, remove internal layer supporting plate (4), outer layer supporting plate (5) and retainingf key (3), the permanent magnet welded with it, extensive
Restore the special sharp grid structure of laser cutting machine, you can continue to process other conventional slab plates.
Technique effect
Main advantages of the present invention are：Existing laser cutting machine is transformed using structure in the present invention, innovation
Use new exclusive point grid to position supporting plate with ectonexine, steel plate during laser cutting is fitted closely with supporting plate, ensure that it is cut
Longitudinal judder is preferably minimized when cutting, and reduces defocusing amount change, and then ensure the surface quality of section；Using magnet reserved in advance
Square hole coordinates welding permanent magnet, and plate horizontal direction is positioned, and ensures that plate relative laser cutting nozzles do not tremble, and then
Ensure horizontal size during laser cutting of sheet, ensure that punching sheet of generator uniformity is good；While special sharp grid are transformed, protect
The function of former special sharp grid is stayed, does not need to change special sharp grid in the former slab of processing, it is only necessary to which bolt supporting plate of dismantling can be processed
Other products, reduce cost and improve processing efficiency at the same time.Meanwhile the present invention uses standardized designs thinking, arrange all fixed
The possible position of key, makes supporting plate for different product and fixed key position provides guidance.
It is the defects of when the present invention solves Laser cutting thin plate, not single to use in processing generator stator-rotator punching
, can also be on the product of other 0.5mm-1mm plates be processed during piece.By intra-company's experiment unit, Vancomycin resistance, the Taohe River
Mouthful, the production verification of moral molten iron turbine generator unit, it is practical, and ensure that product quality, take into account economy, timeliness and
Reliability, the new method and thinking for expanding working ability are provided for laser cutting processing technique method.Laser cutting
Plate has the characteristics that the preparatory period is short, programming is flexible, and when particularly small lot is processed, the Sheet Metal Forming Technology that compares needs to make
For punch die, the characteristics of cost is lower, the cycle is shorter.But since high pressure auxiliary gas blows incision, laser cutting is caused to add
During work thin plate, uniformity is bad, and the mass defects such as dimension overproof, cross-sectional face quality be bad easily occur.
