Embodiment 1
[0071] combine figure 1 , figure 2 and image 3 , the high-precision laser welding machine cutting edge of the present embodiment includes an upper cutting edge group 1 and a lower cutting edge group 2, and the upper cutting edge group 1 includes two cutting edges, and the two cutting edges of the upper cutting edge group 1 are respectively located on On the two sides of the rectangular projection 4, and the cutting surfaces of the two cutting edges of the upper cutting edge group 1 are oppositely arranged; the lower cutting edge group 2 includes two cutting edges, and the two cutting edges of the lower cutting edge group 2 They are respectively arranged on the two inner sides of the rectangular groove 5, and the cutting surfaces of the two cutting edges of the lower cutting edge group 2 are arranged oppositely; the rectangular protrusion 4 is matched with the rectangular groove 5; the upper cutting edge group 1 The two cutting edges and the two cutting edges of the lower c...
Embodiment 2
[0107] The cutting edge of the high-precision laser welding machine of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0108] Wherein, the manufacturing method of single shear blade comprises the following steps:
[0109] Step 1. Raw material preparation for the scissors
[0110] The cutting edge is made of a forged blank, and the components of the forged blank are: C: 0.89%, Si: 0.20%, V: 0.87%, W: 0.45%, Mn: 0.45%, Co: 0.30%, Ti: 0.55%, P: 0.02%, Cr: 11.74%, Mo: 0.45%, and the rest is Fe; firstly cut the cutting edge hair, and the quality of the cut cutting edge hair is: the quality of the finished cutting edge = 2.9; Then, forging the cut scissors at a heating temperature of 1080°C, thickening and elongating the scissors, the forging ratio is 7;
[0111] Step 2. Annealing treatment of forging hair damage
[0112] After step 1 forging, the forged blank is annealed, specifically: first put the forged blank into a heat treatment furn...
Embodiment 3
[0143] The cutting edge of the high-precision laser welding machine of this embodiment is basically the same as that of Embodiment 1, the difference is that:
[0144] Wherein, the manufacturing method of single shear blade comprises the following steps:
[0145] Step 1. Raw material preparation for the scissors
[0146] The cutting edge is made of a forged blank, and the components of the forged blank are calculated by weight percentage: C: 0.82%, Si: 0.10%, V: 070%, W: 0.40%, Mn: 0.25%, Co: 0.20%, Ti: 0.42%, P: 0.01%, Cr: 9.8%, Mo: 0.35%, and the rest is Fe; firstly cut the cutting edge hair, and the quality of the cut cutting edge hair: quality of finished cutting edge = 2.5; Then, forging the cut scissors at a heating temperature of 1040°C, thickening and elongating the scissors, the forging ratio is 6.1;
[0147] Step 2. Annealing treatment of forging hair damage
[0148] After step 1 forging, the forged blank is annealed, specifically: first put the forged blank into t...
