[0026] Such as image 3 As shown, it is a structural schematic diagram of the bending die. The bending die is composed of an upper bending die 2, a limit block 3 and a lower bending die 4. The upper bending die 2 and the lower bending die 4 are combined to limit the The positioning block 3 is arranged on the lower bending die 4 outside the upper bending die 2, and the limiting block 3 limits the vertical movement range of the lower bending die 4, such as Figure 4 , 5 As shown, it is a structural diagram of the upper die of the bending die. The upper die 2 of the bending die is provided with two semicircular holes, and the radius of the hole r1=R1, the radius r2=R2, and the radius of the end of the hole r5=r6=D / 2, the slope of the two holes is 30°, such as Figure 6 , 7 As shown, it is a structure diagram of the lower die of the bending die, the structure of the lower die 4 of the bending die is matched with the upper die 2 of the bending die, and the radius of the semicir...
