Problems solved by technology

[0003] For the materials and processing technology used to make the C-shaped shell, the existing commonly used production process is mainly through forging, ignoring the influence of the thermal processing process on the elastic properties and hardness of the steel, and the produced C-shaped shell has low bearing capacity and low elastic properties. Poor, and cannot meet the requirements for the use of recoverable structures

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...

Abstract

The invention discloses a production process for a C-shaped-opening cylindrical shell with a threshold buckling unloading self-resetting function. The production process mainly comprises a machining technology and a heat treatment technology. The production process specifically comprises the steps of rolling of a steel plate or pouring by means of a mould; drilling after moulding is completed; exposure in a high temperature; normalizing; low-temperature tempering; exposure in a high temperature; quenching (oil cooling); medium-temperature tempering; and natural cooling. According to the heat treatment technology applicable to the C-shaped-opening cylindrical shell with the threshold buckling unloading self-resetting function, the key lies in two times of high-temperature heat treatment at controlled temperatures; through primary heat treatment, internal stress during machining is eliminated, and the design dimension and shape of the plate are maintained; and through secondary heat treatment, the hardness and elasticity of a component are improved, and a metal internal structure is stabilized. The production process is simple, short in period, and low in cost, the produced C-shaped-opening cylindrical shell is good in restorability, the problems that steel plates available in the market are low in hardness and cannot be directly used for recoverable structures are solved, and the production process is beneficial for market application and popularization.

Description

technical field [0001] The invention belongs to the technical field of metal production and processing, and in particular relates to a production process of a C-shaped open cylindrical shell with threshold buckling unloading self-resetting function. Background technique [0002] The C-shaped open cylindrical shell with threshold buckling unloading and self-resetting function is a shock-absorbing and shock-isolation device assembled from a special C-shaped open cylindrical shell, high-strength bolts, and upper and lower connecting steel plates. This device has a large vertical bearing capacity and Rigidity can effectively support the weight of the building, and the seismic isolation bearing can undergo large deformation elastic displacement in the horizontal direction. Cooperating with the damping system and the support protection system, it can also effectively isolate the seismic energy and prevent the seismic energy from being transmitted to the upper structure, effectively...
