Embodiment 1
[0028] see below figure 2 , figure 2 It shows that the blanking device of the present invention has used the metal wires arranged at intervals, and the structure of the wires arranged at intervals is completely different from the receiving plate of the traditional technology, and the metal wires arranged at intervals have played the following roles at least: first, the cam The contact area between the shaft 4 and the metal wire is small, and the metal wire is smooth throughout, which avoids collisions and bumps with the camshaft. Secondly, the sliding speed of the camshaft 4 on the wire is slowed down, avoiding flying out of the connection due to the inertia of the drop. Part 2 risk.
[0029] exist figure 1 Among them, the material receiving part 2 adopts the metal wire structure arranged at intervals, which achieves higher production efficiency through a simple structure.
[0030] As an indispensable part of the present invention, the material selection and manufacture a...
Embodiment 2
[0037] In this embodiment, the material and manufacturing process of the metal wire are further optimized.
[0038] The Ni-based alloy with a weight percentage content of Fe between 10% and 16%, specifically selects 14% Fe content by weight percentage, and also includes the following components (weight percentage): 15% Cr, 0.5% Al, 3 % Mo, 0.2% W, 7% Co, 0.5% C.
[0039] The deformation rate of each section of the wire drawing process is 30%, and the finished product is heat-treated at a constant temperature of 720°C for 12 hours.
Embodiment 3
[0041] The difference between this embodiment and embodiment 2 is:
[0042] The Ni-based alloy with a weight percentage content of Fe between 10% and 16%, the Fe weight percentage content is specifically selected as 16%, including the following components: 20% Cr, 2% Al, 2.5% Mo, 0.9 % W, 5% Co, 0.8% C.
[0043] The deformation rate of each section of the wire drawing process is 35%, and the finished product is heat-treated at a constant temperature of 750°C for 6 hours.
