[0025] 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 scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses an impact-resistant elbow forming device. (Refer to...) Figure 1 and Figure 8 An impact-resistant elbow forming equipment includes a stamping base 1, a sliding table 3 fixedly connected to one side of the stamping base 1, a fixed connecting rod 4 fixedly connected to one side of the stamping base 1, a first hydraulic cylinder 2 fixedly connected to the top of the fixed connecting rod 4, a stamping upper shell 18 fixedly connected to the telescopic end of the first hydraulic cylinder 2, a supporting inclined seat 10 slidably connected inside the sliding table 3, and a feeding mechanism 5 provided inside the sliding table 3.

[0028] The feeding mechanism 5 includes a rack 504, which is fixedly connected to the inner wall of the sliding table 3. A second hydraulic cylinder 501 is fixedly connected to the top of the support inclined seat 10. A sliding seat 11 is fixedly connected to the telescopic end of the second hydraulic cylinder 501. A connecting block 502 is fixedly connected to the top of the sliding seat 11. A large motor 506 is fixedly connected to one side of the support inclined seat 10. A gear 505 is fixedly connected to the output end of the large motor 506. The surface of the gear 505 meshes with one side of the rack 504. A sleeve 503 is fixedly connected to one side of the connecting block 502. A small motor 510 is fixedly connected to the inner wall of the connecting block 502. A support shaft 509 is fixedly connected to the output end of the small motor 510. A rotating cam 507 is rotatably connected to the inner wall of the sleeve 503. Chain wheels 508 are fixedly connected to both the surface of the support shaft 509 and the surface of the rotating cam 507. The two chain wheels 508 are connected by a chain. In the transmission, a sliding rod 511 is slidably connected to the inner wall of the sleeve 503. A spring 512 is provided on the surface of the sliding rod 511. A push plate 513 is fixedly connected to one side of the sliding rod 511. A sliding table 3 installed on one side of the stamping base 1 can be used to support the movement of the feeding mechanism 5, so that it moves the elbow into the stamping base 1 and is shaped by the stamping upper shell 18. A fixed connecting rod 4 installed on one side of the stamping base 1 supports the first hydraulic cylinder 2, so that it can drive the stamping upper shell 18 to move up and down. A large motor 506 installed at the bottom of the support inclined seat 10 can drive the gear 505 to move on one side of the rack 504, thereby driving the elbow to move. The sleeve 503 installed at one end of the connecting block 502 can be used to place the bent pipe. A small motor 510 drives the rotating cam 507 to rotate, so that its protruding part pushes the sliding rod 511 to lock the bent pipe, thereby increasing the connection strength between the sleeve 503 and the bent pipe.

[0029] Reference Figure 3 A connecting pipe 16 is fixedly connected to the top of the connecting block 502, and a ventilation mesh 15 is fixedly connected to the top of the connecting pipe 16. The connecting pipe 16 installed on the top of the connecting block 502 can be used to install a small motor 510, so that the small motor 510 is in communication with the outside air. When the small motor 510 is running, it can increase the heat dissipation effect of the small motor 510.

[0030] Reference Figure 1 The inner wall of the sliding table 3 is fixedly connected to a slide rod 8. The surface of the slide rod 8 is slidably connected to the inner wall of the support inclined seat 10. When the large motor 506 drives the gear 505 to move on the rack 504, the slide rod 8 can increase the stability of the support inclined seat 10 moving in the sliding table 3.

[0031] Reference Figure 1A crash plate 9 is fixedly connected to one side of the support sloping seat 10. There are two crash plates 9. When the sliding seat 11 moves to the extreme position, the crash plate 9 will block the sliding seat 11 and the sliding platform 3 to prevent the sliding platform 3 from colliding with the sliding seat 11.

[0032] Reference Figure 1 A fixed connecting plate 6 is fixedly connected to one side of the sliding platform 3. A fixed rib 7 is fixedly connected between the fixed connecting plate 6 and the sliding platform 3. The fixed connecting plate 6 installed on one side of the sliding platform 3 can fix the sliding platform 3 to the ground by screws, increasing the connection strength between the sliding platform 3 and the ground. The fixed rib 7 installed between the fixed connecting plate 6 and the sliding platform 3 can increase the connection strength between the sliding platform 3 and the fixed connecting plate 6.

[0033] Reference Figure 2 and Figure 4 The inner wall of the sliding table 3 is provided with a ramp 13. A limit seat 12 is fixedly connected to one side of the sliding seat 11. The ramp 13 installed inside the sliding table 3 can guide lubricating oil into the sliding table 3, thereby reducing the friction between the support ramp 10 and the sliding table 3 and extending the service life of the support ramp 10. The limit seat 12 installed on one side of the sliding seat 11 can restrict the sliding seat 11, reduce the force on the second hydraulic cylinder 501, and protect the connection surface between the sliding seat 11 and the support ramp 10.

[0034] Reference Figure 1 and Figure 4 A limiting baffle 17 is fixedly connected to the top of the sliding table 3, and a limiting disc 14 is fixedly connected to the surface of the sleeve 503. The limiting baffle 17 installed on the top of the sliding table 3 can protect the gear 505 and the rack 504 and prevent parts from falling into the sliding table 3. The limiting disc 14 installed on the surface of the sleeve 503 can limit the elbow when the sleeve 503 is pressing against it, so as to avoid collision with the connecting block 502.

[0035] Working principle: The large motor 506 drives the gear 505 to rotate, causing it to slide on the surface of the rack 504. After aligning the sleeve 503 with the elbow, the second hydraulic cylinder 501 pushes the sleeve 503 deeper into the heated and molded elbow. When the elbow falls, it will land on the surface of the sleeve 503. The large motor 506 drives the support inclined seat 10 to move to the front end of the stamping base 1. The small motor 510 pulls the sleeve 503 to move it into the molding cavity of the stamping base 1. Then, the first hydraulic cylinder 2 pushes the stamping upper shell 18 to squeeze the elbow, thereby molding the elbow to the final product size and shape. Finally, the second hydraulic cylinder 501 pushes the elbow upward through the sleeve 503. After removing the elbow, it can be moved to the next process, thus completing the molding and transportation of the elbow.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
