The mounting plate 4 Two slide grooves 42 are provided on the side wall near the second blocking plate 38. The two slide grooves 42 are arranged up and down. The interior of the two slide grooves 42 is provided with a forming structure. The forming structure includes a slider 45 arranged inside the slide groove 42. A limit rod 44 is penetrated through the slider 45. The slider 45 is slidably connected to the limit rod 44. Both ends of the limit rod 44 are fixedly connected to the inner wall of the slide groove 42. A forming half mold 29 is fixedly connected to the side wall of the slider 45.

The guide rod 10 passes through the side plate 2 and is slidably connected to the side plate 2. The hollow water injection pipe 9 and the guide rod 10 are slidably mounted with the side plate 2 through linear bearings. A third spring 41 located on the inner side of the limit sleeve 28 is sleeved on the hollow water injection pipe 9. One end of the third spring 41 is fixedly connected to the inner wall of the limit sleeve 28, and the other end of the third spring 41 is fixedly connected to the side wall of the mounting plate 40.

The end of the inclined rod 34 away from the limit sleeve 28 is rotatably connected with a vertical rod 8. The vertical rod 8 is fixedly connected to the lower side wall of the cross bar 33. Since the limit sleeve 28 can only slide laterally along the direction of the guide rod 10, when the cross bar 33 drives the vertical rod 8 to move downward, since the inclined rod 34 is inclined, when the upper end of the inclined rod 34 moves downward, according to the relevant principles of physical force decomposition, the force will be decomposed into a downward force and a horizontal force at this time. The horizontal force will inevitably squeeze the lower end of the inclined rod 34 to move horizontally, thereby driving the limit sleeve 28 to move horizontally. A pressure pump 3 is provided on one side of the bottom plate 1, and the output end of the pressure pump 3 is connected to a water pipe 4, and the water pipe 4 is connected to the end of the hollow water injection pipe 9.

[0037] The feeding mechanism includes a rotating column 12, and four storage grooves 21 are arranged on the side wall of the rotating column 12. The four storage grooves 21 are arranged at equal intervals along the circumference of the rotating column 12. A rotating rod 11 is horizontally penetrated inside the rotating column 12, and the rotating rod 11 is fixedly connected to the rotating column 12. Four first locking holes 27 are arranged at both ends of the rotating column 12, and the four first locking holes 27 on the same side are arranged at equal intervals along the circumference of the rotating rod 11. The two ends of the rotating rod 11 respectively penetrate two side plates 2, and the rotating rod 11 is rotatably connected to the side plates 2. A mounting hole is arranged on the side wall of the side plate 2 on the right side, and a positioning block 24 is arranged inside the mounting hole. The positioning block A first spring 25 is fixedly connected to the upper end of 24, and one end of the first spring 25 away from the positioning block 24 is fixedly connected to the inner top wall of the mounting hole. Four positioning grooves 22 cooperating with the positioning block 24 are provided on the side wall of the rotating rod 11. The four positioning grooves 22 are arranged at equal intervals along the circumferential direction of the side wall of the rotating rod 11. The positioning block 24 passes through the inner bottom wall of the mounting hole and extends to the inside of the positioning groove 22. The positioning block 24 is inserted into the inside of the positioning groove 22, and the elastic force of the first spring 25 is applied to the positioning block 24, so that the rotating rod 11 can be positioned, thereby ensuring the stability of the rotating rod 11 and the rotating column 12.

[0038] The linkage mechanism includes a moving block 15 arranged inside the moving groove 16, the moving block 15 is fixedly connected to the side wall of the cross bar 33, the lower end of the moving block 15 is fixedly connected to a rack 17, the side wall of the side plate 2 is fixedly connected to a guide sleeve rod 18, the lower end of the rack 17 is slidably inserted inside the guide sleeve rod 18, the left end of the rotating rod 11 is installed with a gear 23 through a one-way bearing 20, the rack 17 is meshed with the gear 23, and by setting the one-way bearing 20, the rack 17 moves down Due to the one-way transmission of the one-way bearing 20, the gear 23 will not be driven to rotate, and when the rack 17 moves up and meshes with the gear 23, it can drive the gear 23 to rotate. A pressure touch switch 19 is provided on the inner bottom wall of the movable groove 16. The pressure touch switch 19 is electrically connected to the pressure pump 3. When the pressure touch switch 19 is triggered by the downward pressure of the movable block 15, the pressure pump 3 can be started through the pressure touch switch 19, and water is injected and pressurized into the interior of the connecting end 47 through the water supply pipe 4 and the hollow water injection pipe 9.

[0039] When the production line of the metal bellows of the present invention is used, the hydraulic cylinder 7 is started to extend, driving the cross bar 33 to move downward, and the pressing block 32 is driven to move downward through the movable rod 30 and the sleeve 31, and the pressing block 32 is pressed down on the top of the bellows body 46. The pressing block 32 cooperates with the rotating column 12 to limit and fix the bellows body 46, thereby ensuring the stability of the bellows body 46 and the stability of the processing of the connecting end 47;

[0040] At the same time, through the vertical rod 8 and the oblique rod 34, since the oblique rod 34 is inclined, when the vertical rod 8 moves down, the inclination angle of the oblique rod 34 gradually tends to be horizontal, and the oblique rod 34 can be used to push the limit sleeve 28 to move laterally. When the limit sleeve 28 moves, the third spring 41 can be used to drive the mounting plate 40 to move synchronously, and the mounting plate 40 can be used to drive the hollow water injection pipe 9 to move, and then the first blocking plate 37 can be driven by the hollow water injection pipe 9 to block the inside of the connecting end 47, and the second blocking plate 38 can be used to block the end of the connecting end 47. The two molding half-molds 29 are located at the opening, and the two molding half-molds 29 can be surrounded outside the connection end 47 at the same time. Then, as the limiting sleeve 28 continues to move, the third spring 41 is compressed, and then the limiting sleeve 28 moves and squeezes the molding half-mold 29, so that the two molding half-molds 29 are close to each other and fit on the outer wall of the connection end 47. The locking block 39 is inserted into the first locking hole 27 and the second locking hole 36, so that the pressing block 32, the rotating column 12, and the limiting sleeve 28 can be fixed to each other, thereby ensuring the stability of the subsequent processing of the connection end 47;

[0041] Then, the pressure pump 3 is started, and water is injected into the interior of the connection end 47 through the water delivery pipe 4 and the hollow water injection pipe 9 to increase pressure, and the annular flange 48 can be extruded on the surface of the connection end 47 in accordance with the inner wall shape of the forming half mold 29, and then the pressure pump 3 is stopped;

[0042] The hydraulic cylinder 7 is then started to contract, driving the cross bar 33 to move upward. When the cross bar 33 moves upward, the moving block 15 is driven to move upward at the same time. The moving block 15 drives the rack 17 to move upward, and the inclined rod 34 can be used to pull the limit sleeve 28 horizontally to reset and move. The two forming half molds 29 move away from each other and open. Then the limit sleeve 28 drives the forming half mold 29 away from the connecting end 47, and the first sealing plate 37 and the second sealing plate 38 are driven to move out of the connecting end 47 through the hollow water injection pipe 9. The water inside the connecting end 47 will fall into the collecting box 1 4, and the pressing block 32 moves upward. Then, when the rack 17 meshes with the gear 23, the gear 23 is driven to rotate, and the rotating rod 11 is driven to rotate through the one-way bearing 20, and the rotating column 12 is driven to rotate through the rotating rod 11. The bellows body 46 can be carried by the rotating column 12 to rotate to the bottom of the pressing block 32, and the subsequent molding process can be carried out, so that the bellows body 46 can be automatically loaded and placed in place. At the same time, the processed bellows body 46 falls onto the discharge guide plate 13 as the rotating column 12 rotates.

[0043] Reference Fig.11A metal bellows comprises a bellows body 46, both ends of the bellows body 46 are provided with connecting ends 47, the outer wall of the connecting end 47 is provided with two annular flanges 48, and a sealing ring 49 is provided between the two annular flanges 48. By applying pressure inside the connecting end 47, the two annular flanges 48 can be quickly formed on the outer wall of the connecting end 47, and then the connecting end 47 and the pipe joint can be connected together by squeezing the sealing ring 49 with the inner wall of the existing pipe joint, so that the bellows connection is simple, fast, low cost and high processing efficiency.
