Technical Field

[0001] The utility model belongs to the technical field of flying shears, and in particular relates to a resettable metallurgical flying shear testing machine. Background Art

[0002] The shearing machine that transversely shears the rolled pieces in operation is called a flying shear. It is a processing equipment that can quickly cut iron plates, steel pipes, and paper rolls. The flying shear is an important equipment used by steel companies to shear metal billets. The quality of its performance will directly affect the production efficiency of the rolling production line and plays an irreplaceable role in the industry.

[0003] The shears in the existing technology are industrial products with a fixed overall structure and are difficult to disassemble. It is impossible to conduct teaching experiments on the equipment during laboratory classes in schools, and it is impossible to understand its internal mechanical principles in detail and accurately, which affects subsequent research on the operating characteristics and optimal design of the shears.

Students can disassemble and assemble the experimental machine independently during experimental classes. It can also be matched with the Internet of Things measurement and control system and corresponding sensors (force sensors, encoders, displacement sensors, torque sensors) to conduct statics and kinematics experiments, so that they can intuitively understand the internal mechanical principles.
