Description

Technical Field

[0001] The invention relates to the technical field of spring production, and in particular to a shearing device and a shearing process for producing steel for aircraft seat springs. Background Art

[0002] The springs used in aircraft seats are mainly used to provide elastic support and shock absorption.

[0003] Specifically, the functions of these springs include: Shock-absorbing spring: A shock-absorbing spring is installed under the seat to reduce the vibration of the seat during flight and improve the passenger's comfort experience.

[0004] Adjustment Springs: In aircraft seat adjustment mechanisms, springs are used to provide resilient support, control the recline angle of the seat, and provide controlled actuation of the seat from the bed position to the upright position.

[0005] Safety Spring: In an aircraft seat belt retractor, a spring is used to keep the belt taut so that it can be quickly retracted and to release the belt quickly in an emergency.

[0006] Based on the above information, it can be determined that the types of springs used in aircraft seats mainly include compression springs and extension springs; compression springs are often used to provide elastic support and shock absorption, while extension springs are used to control the seat's tilt angle and seat position adjustment.

[0007] The springs used in aircraft have relatively high quality requirements, with particular attention paid to the material, elasticity and durability of the springs to ensure optimal comfort and safety during flight.

[0008] The steel used to produce springs needs to be sheared before production. The main reasons are: Using shear strain to store energy: The mechanical energy storage of a spring is equal to strain and stress (energy = force × displacement). Under the same stress, the greater the strain, the more mechanical energy can be stored. Since the elastic modulus of the normal strain (tension and compression strain) of metal materials is much larger than the elastic modulus of the shear strain (shear), the elastic energy storage of metals can be more effectively utilized through shearing.

[0009] Optimize stress distribution: For springs with non-axisymmetric shapes, such as tank suspension springs, shearing can make the stress distribution on the cross section more uniform, thereby improving the performance and life of the spring.

[0010] Removing rolling defects: After rolling, the steel may have irregular deformation parts at the head, tail and edge. These parts need to be sheared off to ensure the dimensional accuracy and surface quality of the spring.

[0011] In summary, the shearing process of spring steel is to more effectively utilize the elastic properties of the material, optimize stress distribution, remove manufacturing defects, and meet the needs of specific applications.

[0012] Spring steel is usually cut to a fixed length before production, but during the production process, spring steel is formed by drawing, winding and other processes. In this process, improper process may cause the diameter or roundness of the steel wire to be insufficient. If springs are produced using spring steel with such defects, the produced springs will be eliminated in subsequent testing and cannot be used, resulting in waste.

[0013] Therefore, we propose a shearing device and a shearing process for producing steel for aircraft seat springs. Summary of the invention

The production data parameters are used to control the spring forming mechanism to produce springs of different types; one of them is the parameter required for the production of high-quality springs, and the other is the parameter required for the production of low-quality springs; S2. When the laser diameter gauge (600) detects that the diameter of the spring steel (700) does not meet the high-quality spring production parameters, the current position is marked, i.e., the length of the wire outlet nozzle (301) of the automatic wire feeding machine (300) is reached at this position, and the length is at least sufficient to produce a high-quality spring; after producing a high-quality spring, the spring is cut off; S3, then controlling the spring forming machine (100) to execute a process corresponding to the parameters required for the production of low-quality springs, and producing low-quality springs; S4, simultaneously controlling the classification mechanism (400) to switch, and cutting off the low-quality springs after the production is completed; and storing the produced low-quality springs separately from the high-quality springs; S5. When the laser diameter gauge (600) detects that the diameter of the spring steel (700) meets the requirement, the process is switched to the process corresponding to the parameters required for high-quality spring production in the same manner as steps S2-S4, and the classification mechanism (400) is controlled to switch, so as to store them separately.
