Description

Technical Field

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

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

[0003] Specifically, the functions of these springs include:

[0004] Shock-absorbing spring: A shock-absorbing spring is provided under the seat to reduce the degree of shock during flight and improve the comfort experience of passengers.

[0005] Adjusting spring: In the aircraft seat adjustment mechanism, the spring provides elastic support, controls the tilt angle of the seat, and performs controlled actuation between the bed position and the upright position of the seat.

[0006] Safety spring: In the aircraft seat belt retractor, the spring is used to keep the seat belt taut, so that the seat belt can be quickly retracted and released quickly in an emergency.

[0007] According to the above information, it can be determined that the types of springs used in aircraft seats mainly include compression springs and tension springs; compression springs are commonly used to provide elastic support and shock absorption, while tension springs are used to control the tilt angle of the seat and the adjustment of the seat position.

[0008] The springs used on aircraft have relatively high quality requirements, especially paying attention to the material, elasticity and durability of the springs; to ensure the best comfort and safety during flight.

[0009] The steel used to produce springs needs to be sheared before production, and the main reasons are:

[0010] Utilize shear strain to store energy: The mechanical energy storage of a spring is equal to the 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 (tensile and compressive strain) of metal materials is much greater than the elastic modulus of the shear strain (shearing), shear can be used to more effectively utilize the elastic energy storage of metals.

[0011] Optimize stress distribution: For springs with non-axisymmetric shapes, such as tank suspension springs, shear can make the stress distribution on the cross-section more uniform, thereby improving the performance and lifespan of the spring.

[0012] Remove rolling defects: After rolling, the steel may have irregular deformed parts at the head, tail and edges, and these parts need to be sheared off to ensure the dimensional accuracy and surface quality of the spring.

[0013] In summary, the shearing process of spring steel is to make more effective use of the elastic properties of the material, optimize the stress distribution, remove manufacturing defects, and meet the requirements of specific applications.

[0014] Since spring steel is generally sheared to a fixed length before producing springs, during the production process of spring steel, it is formed through processes such as drawing and winding. During this process, the diameter or roundness of the steel wire may be insufficient due to improper processes. If springs are produced using spring steel with such defects, the produced springs will also be eliminated during subsequent inspections and cannot be used, resulting in waste.

[0015] Therefore, we propose a shearing device and shearing process for the steel used in aircraft seat springs. Summary of the Invention

[0016] In view of this, the present invention provides a shearing device and shearing process for the steel used in aircraft seat springs, which are used to solve the problem that in the production of aircraft seat springs in the prior art, some products that do not meet the requirements are wasted in vain and are likely to increase the detection cost in subsequent processes.

Brush hairs are fixedly connected inside the circle. The air outlet at one end of the pneumatic quick connector is aligned with the position of the turbine blades. By connecting the compressed air source to the pneumatic quick connector, the high-speed air pressure drives the turbine blades to rotate, so that the surface of the spring steel can be cleaned by the brush hairs.

[0024] Preferably, a vibration motor is fixedly installed on the outer wall of the sleeve. A spring bellows is installed inside the sleeve.

A sliding rod is slidably installed inside the sliding sleeve. The end of the sliding rod is fixedly connected to a support frame. An electric push rod is fixedly installed on the support frame.

[0028] Preferably, the sorting mechanism includes a support plate. A support frame is fixedly connected to the center of the top of the support plate. Openings are respectively provided at both ends of the support frame. A storage box A and a storage box B are respectively placed at both ends of the top of the support plate. A triangular receiving block is slidably installed in the upper part of the support frame.

[0033] S2. When the laser diameter gauge detects that the diameter of the spring steel does not meet the production parameters of the high-quality springs, mark the position at this time, that is, the length from this position to the outlet nozzle of the full-automatic wire feeder, and this length is at least sufficient to meet the requirement of producing one high-quality spring; after producing one high-quality spring, cut it off.

[0034] S3. Then control the spring forming machine to execute the process corresponding to the parameters required for the production of low-quality springs to produce low-quality springs.

[0035] S4. At the same time, control the sorting mechanism to switch. After the production of the low-quality springs is completed, cut it off; store the produced low-quality springs and high-quality springs separately.

[0036] S5. When the laser diameter gauge detects that the diameter of the spring steel meets the requirements, in the same way as in steps S2 - S4, switch to the process corresponding to the parameters required for the production of high-quality springs, and at the same time control the sorting mechanism to switch, and store them separately in this way.

[0037] Implementing the embodiments of the present invention will have the following beneficial effects:

[0039] Before the spring is formed, the spring steel is detected.

At the same time, during production, they are directly separated into two types of products; there is no need to detect and pick out in the subsequent process, saving the process cost;

[0040] If there is no need to produce other products during production (low-quality requirements), and if it is possible to use all spring steel materials that meet the requirements as much as possible, it is also possible to directly cut off the spring steel material after the laser diameter gauge detects it by marking the position and then directly cutting it with a shear knife after it comes out of the outlet nozzle of the full-automatic wire feeding machine for spring steel materials;

[0041] The cleaning mechanism can directly clean online, which can not only improve the detection accuracy of the laser diameter gauge and avoid false detection, but also remove the dust adhering to the surface of the spring steel material, facilitating subsequent spring forming production; moreover, the structure of the cleaning mechanism is simple, there is no dead angle in cleaning, and it is easy to implement.

[0063] During implementation, it also includes a PLC controller (not shown in the figure), the signal output end of the laser diameter gauge 600 is connected to the signal input end of the PLC controller, and the spring forming machine 100, the full-automatic wire feeder 300, the sorting mechanism 400 and the hydraulic cylinder 201 are respectively controlled by the PLC controller.

[0064] Among them, the full-automatic wire feeder 300: consists of a material tray, a base, a motor, a reducer, a frequency converter, an induction switch, a relay and electrical components, etc., and is responsible for automatically, continuously and efficiently conveying the wire to the designated processing position or the next process. The full-automatic wire feeder 300 is an existing technology.

[0065] Among them, the spring forming machine 100: is an automated device dedicated to manufacturing various types of springs, and can form the metal wire into the required spring shape through steps such as curling, compressing, and stretching, and also belongs to the existing technology.

[0066] As Figure 3 shown, the cleaning mechanism 500 includes a sleeve 502, a round hole 504 is opened at the center of one end of the sleeve 502, and a pneumatic quick coupling 503 is also installed at this end of the sleeve 502. The other end of the sleeve 502 is installed with an end cover 505, and an opening 506 is opened in the middle of the end cover 505. A linear bearing 507 is fixedly installed inside the sleeve 502, a cylinder 508 is movably installed inside the linear bearing 507, a turbine blade 509 is fixedly connected to the inner wall of the cylinder 508, a circle 510 is connected to the center of the cylinder 508 through the turbine blade 509, and a brush hair 511 is fixedly connected inside the circle 510; among them, the air outlet of one end of the pneumatic quick coupling 503 is aligned with the position of the turbine blade 509; by connecting the compressed air source to the pneumatic quick coupling 503, the high-speed air pressure is used to drive the turbine blade 509 to rotate, so that the surface of the spring steel 700 can be cleaned by using the brush hair 511 (the brush hair 511 can be selected as pig bristle).

[0067] Among them, when the cleaning mechanism 500 is in use, the compressed air gas source is connected to the pneumatic quick connector 503. The compressed air blowing the turbine blade 509 can cause the circle 510 to rotate, and at the same time can drive the brush bristles 511 to clean the surface of the spring steel 700.

[0068] During implementation, as Figure 2 shown in, a vibration motor 501 is fixedly installed on the outer wall of the sleeve 502. A spring bellows 512 is installed inside the sleeve 502. One end of the spring bellows 512 abuts against one side surface of the end cover 505, and the other end of the spring bellows 512 is fixedly connected to a thrust bearing 513. One side surface of the thrust bearing 513 abuts against one end of the cylinder 508.

The spacing gap is convenient for dust discharge under high air pressure.

[0070] During implementation, as Figure 5 shown in, the classification mechanism 400 includes a support plate 401. A support frame 402 is fixedly connected to the center of the top of the support plate 401. Openings 407 are respectively arranged at both ends of the support frame 402; a storage box A403 and a storage box B404 are respectively placed at both ends of the top of the support plate 401. A triangular receiving block 409 is slidably installed in the upper part of the support frame 402. The triangular receiving block 409 can move horizontally under the drive of the drive mechanism, so as to selectively drop the formed springs falling into the support frame 402 into the storage box A403 or the storage box B404.

[0071] Specifically, two parallel sliding grooves 408 are respectively opened on both inner walls of the support frame 402. Sliders 410 are respectively fixedly connected to both side walls of the triangular receiving block 409. The sliders 410 are slidably installed in the sliding grooves 408.

[0072] During implementation, the drive mechanism includes a forward and reverse motor 405 fixedly installed outside the support frame 402. The output shaft of the forward and reverse motor 405 penetrates through the inside of the support frame 402 and is fixedly sleeved with a gear 406. A rack 411 is fixedly connected to one side of the triangular receiving block 409. The gear 406 is meshed with the rack 411. The forward and reverse motor 405 is controlled by a PLC controller.

[0073] Specifically, a shearing process for the steel used in the production of aircraft seat springs adopts the above-mentioned shearing equipment for the steel used in the production of aircraft seat springs, and specifically includes the following steps:

[0074] S1. Set the production data parameters of two types of springs on the PLC controller. The production data parameters are used to control the spring forming mechanism to produce springs of different models; one is the parameters for the production requirements of high-quality springs, and the other is the parameters for the production requirements of low-quality springs.

[0075] S2. When the laser diameter gauge 600 detects that the diameter of the spring steel 700 does not meet the production parameters of high-quality springs, mark the position at this time, that is, the length from this position to the outlet nozzle 301 of the full-automatic wire feeder 300, and this length is at least sufficient to meet the requirement of producing one high-quality spring; after producing one high-quality spring, cut off.

[0076] S3. Then control the spring forming machine 100 to execute the process corresponding to the parameters for the production requirements of low-quality springs to produce low-quality springs.

[0077] S4. At the same time, control the sorting mechanism 400 to switch. After the production of low-quality springs is completed, cut off; store the produced low-quality springs and high-quality springs separately.

[0078] S5. When the laser diameter gauge 600 detects that the diameter of the spring steel 700 meets the requirements, in the same way as steps S2 - S4, switch to the process corresponding to the parameters for the production requirements of high-quality springs, and at the same time control the sorting mechanism 400 to switch, and store them separately in this way.

[0079] Embodiment 2:

[0080] Different from Embodiment 1, the laser diameter gauge 600 is straddled on the spring steel 700, and the laser diameter gauge 600 can be translated along the axial direction of the spring steel 700 through the translation mechanism 800.

[0081] Specifically, the translation mechanism 800 includes two sets of sliding sleeves 801 fixedly connected to one side of the laser diameter gauge 600. A sliding rod 803 is slidably installed inside the sliding sleeve 801. The end of the sliding rod 803 is fixedly connected to the support frame 200. An electric push rod 804 is fixedly installed on the support frame 200. One end of the piston rod of the electric push rod 804 is fixedly connected to one side of the laser diameter gauge 600 through a connecting rod 802, and the electric push rod 804 is controlled by the PLC controller.

[0082] The translation mechanism 800 is used to adjust the distance between the laser diameter gauge 600 and the wire outlet nozzle 301 of the full-automatic wire feeder 300. Assuming this distance is L, in implementation, the length of L can be adjusted by the translation mechanism 800. When producing a spring steel material for an aircraft seat spring (high-quality spring), the material length used remains unchanged (this length is a), and when producing a spring for other purposes (low-quality spring), the material length used for the spring steel material also remains unchanged (this length is b). Among them, L is at least greater than a and b. In this way, during production, if a non-compliant situation is detected, the production of the spring currently being produced can still be completed.

The accompanying drawings show the preferred embodiments of the present application, but do not limit the patent scope of the present application. The present application can be implemented in many different forms.

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.
