Background
With the rapid development of the nuclear industry, the nuclear energy occupies heavier and heavier proportion in the national economy development; the field of nuclear energy production is more and more, wherein the functions of power generation, heat supply and the like are particularly outstanding; in addition, the more and more serious energy and environmental crisis promote the advantages of clean energy such as nuclear power to reappear, and nuclear power also continues to play an important role in future low-carbon energy in the world; pressurized water reactors are commonly adopted in nuclear power in China, so the processing of the grid straps of the nuclear fuel assemblies is also particularly important.
The inner strip punching device with application number CN201010143073.8 can process a grid strip, which comprises a preforming part, a punching punch for forming position control holes at a specified interval on a processed plate material, and a shearing punch for cutting the processed plate material with the position control holes at a set length; a hole detection unit for recognizing the position of the position control hole; a material supply unit configured to supply the plate material to be processed discontinuously at intervals of the position control holes; a pattern forming section including a plurality of pattern-pressing punches for forming a pattern on the work sheet supplied from the material supply section; and a control unit for controlling the driving of the material supply unit and the pattern forming unit based on the position of the hole detected by the hole detection unit and a molding program selected from molding programs of molding types input in advance.
However, most of the conventional grid straps are formed on a wide strap at one time, and the wide strap is deformed greatly and has poor stability during processing, so that the grid straps are poor in processing effect.
Disclosure of Invention
The invention aims to provide a grid strip processing method to solve the technical problem that the grid strip processing method in the prior art is poor in processing effect. The technical effects that can be produced by the preferred technical scheme in the technical schemes provided by the invention are described in detail in the following.
In order to achieve the purpose, the invention provides the following technical scheme:
