Embodiment 1
[0079] The present invention has adopted a kind of manufacturing method of nuclear fuel strip mould, specifically comprises the following steps:
[0080] S1: Feed the long strip-shaped material, punch multiple positioning holes along the feeding direction, and divide the long strip-shaped material into multiple pieces according to the number and position of the positioning holes; each row has 3 Each blank has the same number of positioning holes, which is 4, and the punching positions of the positioning holes on each blank are the same, on the four corners of the blank; the positioning holes are conducive to improving accuracy and facilitating subsequent punching Multiple or single blanks.
[0081] S2: positioning through the positioning hole, punching and punching down multiple blanks with the positioning hole;
[0082] S3: Punching strip characteristic shape grooves on the blank after punching;
[0083] S4: Punching the solid part between the characteristic outline grooves...
Embodiment 2
[0090] The present invention adopts the above-mentioned manufacturing method to manufacture the corresponding nuclear fuel strip mold, including the clamping piece mold. The strip characteristic shape groove punched in the above-mentioned manufacturing method is the clamping piece mold boundary groove, and the clips in the boundary groove The holder pattern is a rigid part protruding inwardly of the tablet.
[0091] The rigid part has enough rigidity not to be deformed when the strip is made, so as to ensure the precision of the characteristic shape groove of the strip.
[0092] exist figure 1 Among them, the clamping part model of the present embodiment can be the first clamping part model 1, and the first clamping part model 1 comprises the footing die 11 that is positioned at its end, is distributed on the footing die 11 The first groove body 12 that is arranged continuously; The first holder mold 1 also has the first protruding belt mold 13 between the 4 footing molds 11;...
