Description

Technical Field

[0001] The utility model relates to the technical field of safety spring piece crimping testing, in particular to a safety spring piece crimping testing machine. Background Technique

[0002] Safety spring pieces are important components that play a key role in various devices and systems. They are usually designed to withstand specific pressures, tensile forces or impact forces, and maintain stable performance under the action of these forces to ensure the safe operation of the entire system. For example, in the braking system of an automobile, safety spring pieces can help maintain the correct position and pressure of the braking components, ensuring the reliability of braking. In the buffer device of an elevator, the spring piece can play a buffering role when the elevator descends abnormally, reducing the impact force and protecting the lives of passengers;

[0003] For some existing safety spring piece crimping testing machines, when conducting crimping tests on safety spring pieces, first place the safety spring pieces on the machine table, then press the safety spring pieces downward through a pressing block, and then conduct tests through a pressure sensor;

[0004] The following problems exist in some traditional safety spring piece crimping testing machines: when conducting crimping tests on safety spring pieces, when the safety spring pieces are not placed stably, the safety spring pieces will pop out when they are pressed downward, which may cause harm to employees.
