Stamping device for inner strap

Abstract

The invention provides a stamping device for an inner strap. The device comprises a pre-forming part, a hole detection part, a material supply part, a pattern forming part and a control part, wherein the pre-forming part comprises a piercing punch for forming position control holes on a processed plate at regular intervals, and a cutting punch for cutting off the processed plate with the position control holes according to set length; the hole detection part identifies the positions of the position control holes; the material supply part discontinuously supplies the processed plate according to the interval of the position control holes; the pattern forming part consists of a plurality of pattern stamping punches which are used for forming patterns on the processed plate supplied by the material supply part; and the control part controls to drive the material supply part and the pattern forming part based on the positions of the position control holes, which are detected by the hole detection part, and a forming program selected from pre-input forming programs for various forming types.

Description

technical field [0001] The invention relates to a stamping device for inner strips. Background technique [0002] A grid is used to properly maintain the interval between fuel rods in the nuclear reactor core, to suppress the vibration of the rods, to support the fuel rods in the axial direction, and to restrain the rods in the vertical direction for the longitudinal movement. One type of common grid design is as follows: comprising a plurality of inner strips which together form an egg-basket type (egg-basket) having roughly square cells each containing fuel rods. crate). [0003] Such an inner strap (1) is formed into a desired pattern by stamping a metal sheet. The inner strip is not limited to a specific shape, such as figure 1 , 2 , As shown in 3, various shapes are formed, so there is a problem that a corresponding press equipment should be provided. [0004] Specifically, in stamping forming has such as figure 1 When the inner strip 1 of the pattern shown, the A...
