Description

Technical Field

[0001] This utility model provides a stamping fixture for aviation heads, belonging to the field of aviation connector technology, and particularly relates to a stamping fixture for aviation head core and outer shell. Background Technology

[0002] Aviation connectors are key components used in electrical, hydraulic, or pneumatic systems in the aviation field. They are mainly used to achieve reliable connections between different devices or system components, ensuring that signals, liquids, or gases can be transmitted safely and efficiently during flight. Their design typically needs to meet stringent aviation standards and features high strength, high temperature resistance, vibration resistance, waterproofing, dustproofing, and lightweighting to adapt to complex and ever-changing flight environments and ensure the normal operation of aviation systems.

[0003] The existing stamping process for aerospace connectors lacks a cushioning device. In this case, the impact force generated during stamping may lead to accelerated wear on the mold and equipment, thereby affecting the precision and quality of the parts. In addition, the lack of cushioning may also cause stress concentration in the metal material during stamping, which may lead to cracks or deformation, affecting the reliability and service life of the aerospace connectors. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a stamping fixture for aero-machine head core and outer shell, which solves the problems of severe mold wear, reduced part precision and low production efficiency caused by lack of buffering in the existing stamping process.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stamping aviation head rubber core and outer shell fixture, including a connector, the lower end of which is connected to a stamping base tube sleeved on its outside via a fixedly connected corrugated tube, the inside of which is connected to a rubber core structure via a corrugated groove; the rubber core structure includes a clip corresponding to the corrugated groove, the clip has a buffer rubber rod penetrating through it inside, and a conical return spring is sleeved on the outside of the buffer rubber rod.

[0006] Preferably, the core structure is made of rubber, and the buffer rod is fixedly connected with symmetrically distributed locking blocks corresponding to the return spring. A blocking surface placed on the locking block is fixed to one end of the buffer rod.

[0007] Preferably, the lower part of the card has a connecting shell that fits into itself, and the end of the connecting shell away from the card has an inclined surface with a diameter smaller than the maximum diameter of the return spring.

[0008] Preferably, the end of the connecting shell furthest from the card is fitted with a corresponding limiting frame, which ensures the positioning and sliding of the buffer rubber rod.

[0009] Preferably, a rubber ring is fitted on the stamping base tube to ensure a buffered connection at the joint of the stamping base tube.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] This invention achieves a buffering function between the rubber core and the outer casing fixture during the stamping of the aero-connector by incorporating a bellows at the lower end of the connector and a rubber core structure inside the bellows. The rubber core structure further incorporates a buffer rod and a return spring. When impact forces are generated during stamping, the bellows and rubber core structure absorb and disperse the impact force, while the buffer rod, under the action of the return spring, further absorbs and mitigates the impact force, thereby reducing direct impact on the mold and equipment, reducing wear, and improving the precision and quality of the parts. Simultaneously, this buffering design effectively avoids stress concentration in the metal material during stamping, reducing the risk of cracks or deformation and enhancing the reliability and service life of the aero-connector. Through this innovative structural design, this invention successfully solves the problem of the lack of a buffering device in the stamping process of aero-connectors in the prior art.

[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a stamping fixture for aero-head rubber core and outer shell, including a connector 1. The lower end of the connector 1 is connected to a stamping base tube 3 sleeved on its exterior via a corrugated tube 2. The interior of the corrugated tube 2 is connected to a rubber core structure 5 via a corrugated groove 4. The rubber core structure 5 includes a retainer 6 corresponding to the corrugated groove 4. The retainer 6 has a buffer rubber rod 7 that passes through it, and a conical return spring 8 is sleeved on the outside of the buffer rubber rod 7. In addition, the rubber core structure 5 is made of rubber material, and symmetrically distributed retaining blocks 9 corresponding to the return spring 8 are fixedly connected to the buffer rubber rod 7. A blocking surface 10 placed on the retainer 6 is fixedly connected to one end of the buffer rubber rod 7.

[0023] In this embodiment, by designing the core structure 5 as a rubber material, its elasticity and buffering capacity during the stamping process are enhanced, effectively absorbing impact force and reducing wear on the mold and equipment. The cooperation between the locking block 9 and the return spring 8 ensures that the buffer rubber rod 7 can quickly return to its original position after being impacted, improving the response speed and service life of the fixture. The setting of the blocking surface 10 ensures the correct positioning of the buffer rubber rod 7 within the locking piece 6, preventing it from shifting during the stamping process and ensuring stamping accuracy.

[0024] Furthermore, the fitting design of the connecting shell 11 and the clip 6, guided by the inclined surface 12, allows the return spring 8 to move smoothly within the connecting shell 11. Simultaneously, the use of the limiting frame 13 further ensures the stable sliding of the buffer rubber rod 7, preventing excessive extension or contraction, thus guaranteeing stability and reliability during the stamping process. The rubber ring 14 provides additional cushioning at the connection point of the stamping base tube 3, further reducing the transmission of impact force during stamping and improving the overall durability and stamping quality of the fixture. These carefully designed features work together to give the stamping aviation head rubber core and outer shell fixture of this invention significant advantages in improving production efficiency and product quality.

[0025] like Figure 3 and Figure 4 As shown, the lower part of the locking component 6 is equipped with a connecting shell 11 that fits into itself. The end of the connecting shell 11 away from the locking component 6 has a slope 12 with a diameter smaller than the maximum diameter of the return spring 8. Simultaneously, a corresponding limiting frame 13 is fitted around the outer end of the connecting shell 11 away from the locking component 6, ensuring the positioning and sliding of the buffer rubber rod 7. A rubber ring 14 is fitted onto the stamping base tube 3, ensuring a buffered connection at the joint of the stamping base tube 3. These design features collectively improve the buffering performance and operational stability of the fixture.

[0026] In this embodiment, by employing a rubber core structure 5, the fixture can maintain stable performance under different temperature and pressure conditions. Simultaneously, the softness of rubber helps reduce noise and vibration during stamping. The symmetrically distributed locking blocks 9, in conjunction with the return spring 8, not only improve the cushioning effect but also ensure that the buffer rod 7 can smoothly and quickly return to its initial position after being impacted, thereby improving the continuity and efficiency of the stamping process.

[0027] The design of the blocking surface 10 provides a stable support point for the buffer rod 7, preventing it from shifting or being damaged under high pressure, thus enhancing the overall stability of the fixture. The fitting design of the connecting shell 11 and the clamp 6, guided by the inclined surface 12, allows the return spring 8 to freely extend and retract within the connecting shell 11, while the limiting frame 13 ensures the positioning accuracy of the buffer rod 7 during extension and retraction, preventing excessive movement and thus guaranteeing the accuracy and repeatability of the stamping process.

[0028] The rubber ring 14 plays a crucial buffering role at the connection of the stamping base tube 3. It absorbs and disperses the impact force generated during the stamping process, reducing damage to the mold and equipment and extending the service life of the fixture. In addition, the rubber ring 14 also helps to improve the sealing of the connection, preventing leakage during the stamping process and ensuring the safety and reliability of the stamping process.

[0029] In use, first, fix the connector 1 in a suitable position on the stamping equipment to ensure its stability. Then, fix the bellows 2 to the lower end of the connector 1, and sleeve the stamping base tube 3 on the outside of the bellows 2. Next, install the rubber core structure 5, so that it is connected to the inside of the bellows 2 through the bellows groove 4. The rubber core structure 5 includes a clip 6, and a buffer rubber rod 7 is provided inside the clip 6. A conical return spring 8 is sleeved on the outside of the buffer rubber rod 7 to provide necessary cushioning. Then, align the clip 9 fixedly connected to the buffer rubber rod 7 with the return spring 8, and place the blocking surface 10 connected to the fixed block at one end of the buffer rubber rod 7 on the clip 6 to ensure the correct positioning of the buffer rubber rod 7. Next, fit the connecting shell 11 below the clip 6. An inclined surface 12 is provided at one end of the clamping part 6 to guide the movement of the return spring 8. At the same time, the limiting frame 13 is sleeved on the outside of the end of the connecting shell 11 away from the clamping part 6 to ensure the positioning and sliding of the buffer rubber rod 7. Finally, a rubber ring 14 is sleeved on the stamping base tube 3 to ensure the buffer connection at the connection of the stamping base tube 3. After completing the above steps, the stamping operation of the aviation head rubber core and the outer shell can be carried out. During this process, the bellows 2 and the rubber core structure 5 will absorb and disperse the impact force, and the buffer rubber rod 7 and the return spring 8 will provide additional buffering, reduce the wear on the mold and equipment, and improve the stamping accuracy and quality. At the same time, the rubber ring 14 will also provide buffering at the connection of the stamping base tube 3, further reducing the transmission of impact force and ensuring the stability and safety of the entire stamping process.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
