Embodiment Construction
[0022] The invention mainly includes three aspects, namely, the design of iron-clad repair tooling, the design of pressurized auxiliary tooling, and the process of blade replacement and iron-clad repair.
[0023] Iron-clad repair tool
[0024] Iron-clad repair tool 2 adopts a segmented design, which is the same as the segment and length of blade 1. The repair tool is divided into upper and lower molds. After the molds are closed, it has a U-shaped die structure. The inner shape is the same as the outer shape of the blade 1 ( Iron-clad appearance) is the same, and each section of iron-clad needs 1 set.
[0025] Pressurized auxiliary tooling
[0026] The pressurized auxiliary tooling is proposed to improve the bonding performance of the clad iron, and its structure includes the leading edge stopper 3, the trailing edge stopper 9, the pressurized nut 4, the spring 7, the gasket 5 and so on. The auxiliary pressurization tooling includes a front edge stopper 3, a pressurization n...
