Problems solved by technology

[0002] Compared with punching and processing plates by presses, laser cutting plates have the advantages of short production preparation period, short cycle, low cost and more flexibility in small batch processing, and because laser cutting requires high-pressure auxiliary gas protection, combustion and slag removal, in When processing generator thin plate sectors, especially when the thickness of the plate is between 0.5mm-1mm, the high-pressure auxiliary gas blows the laser cutting incision, resulting in constant changes in defocus, poor surface quality of the section, and horizontal wavy cutting trajectory, resulting in a size out of tolerance

Embodiment Construction

[0015] 1) Firstly, according to the edge contour of the generator stator and rotor punching sheet drawing and the holes are offset 4mm toward the inner direction of the punching sheet to form an internal supporting plate laser cutting program, then offset 4mm toward the outer direction of the punching sheet, and form an external supporting plate with the appropriate outer contour Plate laser cutting procedure. According to the prepared program, the positions of the fixed keys close to, on the outer edge of the inner pallet and the outer edge of the outer pallet are randomly selected, and the coordinate positions are recorded for use in making the inner pallet and the outer pallet, such as image 3 shown;

[0016] 2) Design the connection quantity and position of positioning tools: according to the pre-prepared drawings, select the positions of the fixed keys close to the outer edges of the inner pallet 4 and the outer pallet 5, and the number of fixed keys is required to be no...

Abstract

The invention relates to a process method for electric generator sheet sector pieces through complete high-precision positioning laser cutting. A standard high-precision positioning method is adopted, and according to the method, parts of a tip gate, a fixed key, a connecting part, an inner supporting plate, an outer supporting plate and the like are assembled. The beneficial effects that the problems that when a laser cutting machining process method is used for machining sheets, the size precision is low, repeatability is poor, and the surface quality is poor are solved, the application range of board laser cutting machining is effectively expanded, it is ensured that an original laser cutting machine structure is easy to restore, and machining of a conventional thick board is not affected are achieved.

Description

technical field [0001] The invention relates to a process method for cutting thin-plate sectors of a generator by adopting a full-type high-precision positioning laser. Background technique [0002] Compared with punching and processing plates by presses, laser cutting plates have the advantages of short production preparation period, short cycle, low cost and more flexibility in small batch processing, and because laser cutting requires high-pressure auxiliary gas protection, combustion and slag removal, in When processing generator thin plate sectors, especially when the thickness of the plate is between 0.5mm-1mm, the high-pressure auxiliary gas blows the laser cutting incision, resulting in constant changes in defocus, poor surface quality of the section, and horizontal wavy cutting Track, which in turn leads to dimension out-of-tolerance. Contents of the invention [0003] The present invention provides a process method for cutting generator thin plate sectors by usi...
