A processing mold and processing method for a fuel assembly grid strip

Abstract

The invention discloses a machining die for fuel assembly grillwork strips. The machining die comprises following parts including a main rack, a controller, a control unit, an inner strip machining die body and an outer strip machining die body; the main rack is provided with one or more airway air discharge pipelines; the controller is electrically connected with the main rack and has two different air discharge modes; the controller is a control unit which controls the corresponding airway air discharge pipelines to discharge air in sequence in a certain air discharge mode; the inner strip machining die body can be detachably connected with the main rack and used for machining one or more sets of different inner strips; the outer strip machining die body can be detachably connected withthe main rack and used for machining one or more sets of different outer strips; the inner strip machining die body and the outer strip machining die body are provided with one or more air cylinder assemblies which make corresponding air cylinders work according to different air discharge modes selected through the controller after being connected with the airway air discharge pipelines. The invention further discloses a machining method of the machining die for the fuel assembly grillwork strips. By means of the machining die for the fuel assembly grillwork strips and the machining method, the cost is reduced, the space is saved, and automated operation is achieved.

Description

technical field [0001] The invention relates to the technical field of processing a fuel assembly grid strip, in particular to a processing mold and a processing method for a fuel assembly lattice strip. Background technique [0002] With the rapid development of the nuclear industry, the proportion of nuclear energy in the development of the national economy is becoming more and more important. There are more and more fields of nuclear energy production, especially for functions such as power generation and heating. The total installed capacity of nuclear power plants currently built and under construction in China is 20 million kilowatts, and it is expected to be about 40 million kilowatts by 2020. From the perspective of the general trend of nuclear power development, the technical route and strategic route for China's nuclear power development have been clarified and are being implemented. The increasingly serious energy and environmental crisis has prompted the reappe...

Problems solved by technology

[0003] Since the nuclear fuel assembly grid consists of 1 type of outer strip and 7 types of inner strips, 8 sets of corresponding molds must be equipped during the processing process, which leads to high cost and takes up a large space, so it needs to be improved
