Embodiment 1
[0024] The technological process of the C-shaped open cylindrical shell with self-resetting function mainly includes: mechanical processing technology and heat treatment technology. refer to figure 1 , the specific production process is, steel plate rolling or mold casting → drilling after forming → high temperature overheating → normalizing → low temperature tempering → high temperature overheating → quenching (oil cooling) → medium temperature tempering → natural cooling. The C-shaped shell member is made of manganese steel with grade 65, and the thickness of the steel plate is 1.2mm. First, according to figure 2 Manufacture 6 pieces of corresponding tensile members as shown, and then make a C-shaped shell according to the following heat treatment process, of which 3 pieces of tensile members and C-shaped shells have the same heat treatment process, and the other 3 pieces of tensile members are not subjected to heat treatment as a comparison . Described technological proc...

[0033] The technological process of the C-shaped open cylindrical shell with self-resetting function mainly includes: mechanical processing technology and heat treatment technology. refer to figure 1 , the specific production process is, steel plate rolling or mold casting → drilling after forming → high temperature overheating → normalizing → low temperature tempering → high temperature overheating → quenching (oil cooling) → medium temperature tempering → natural cooling. The C-shaped shell member is made of manganese steel with grade 65, and the thickness of the steel plate is 1.5mm. Firstly, according to image 3 As shown, three corresponding tensile members are manufactured, and then the C-shaped shell is manufactured according to the following heat treatment process. The heat treatment process of the tensile member and the C-shaped shell is the same. Described technological process specifically comprises the following steps:
