Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a corrugated pipe forming machine, including a bottom plate 1 and a mold 6, the mold 6 is divided into two groups, the inner wall shape of the two groups of molds 6 after being combined together matches the outer wall shape of the corrugated pipe, the two groups of molds 6 are arranged in a mirror image, and the mirror image arrangement is set to ensure that the areas where the two groups of molds 6 are close to each other can just touch, the inner wall of the bottom plate 1 passes through and is rotatably connected with a rotating rod 2, the top of the rotating rod 2 is fixedly connected with a rotating wheel 3, the outer wall of the rotating wheel 3 is transmission-connected with a conveyor belt 4, the transmission direction of the left conveyor belt 4 is counterclockwise, and the transmission direction of the right conveyor belt 4 is clockwise.

[0035] Reference Figure 3 , Figure 6 and Figure 7 A control mechanism 5 is provided on the outside of the conveyor belt 4, and the control mechanism 5 includes a protection block 51. A slide groove 52 is provided at the bottom end of the protection block 51. The shape of the slide groove 52 is a rectangular parallelepiped. A slide bar 53 is slidably connected to the inner wall of the slide groove 52. The width of the slide bar 53 matches the width of the slide groove 52. The bottom end of the slide bar 53 is fixedly connected to the bottom end of the mold 6. The end of the slide bar 53 away from the rotating wheel 3 is elastically connected to the inner wall of the slide groove 52 through a spring 54. One end of the spring 54 is fixedly connected to the end of the slide bar 53 away from the rotating wheel 3, and the other end of the spring 54 is fixedly connected to the inner wall of the slide groove 52. The setting of the spring 54 ensures that when the mold 6 is not subjected to force, it can be located at a position far away from another group of molds 6.

[0036] Reference Figure 4 - Figure 6The control mechanism 5 also includes a control block 55, the top of which is fixedly connected to the bottom of the mold 6, and an anti-deflection component 58 is arranged inside the control block 55. The anti-deflection component 58 includes a working groove 581, which is opened on the inner wall of the left end control block 55 away from the rotating rod 2, and an anti-deflection block 582 is slidably connected to the inner wall of the working groove 581. The end of the anti-deflection block 582 close to the rotating rod 2 is elastically connected to the inner wall of the working groove 581 through a spring 583, and one end of the spring 583 is fixedly connected to the end of the anti-deflection block 582 close to the rotating rod 2 The other end of the spring 583 is fixedly connected to the inner wall of the working groove 581, and a positioning groove 584 is provided at the end of the right end control block 55 away from the rotating rod 2. The position and shape of the positioning groove 584 are consistent with the working groove 581. The top view of the anti-deflection block 582 is a rectangular block with two triangular grooves cut out. The width of the anti-deflection block 582 is consistent with the positioning groove 584. Through the matching shape setting, it is ensured that the anti-deflection block 582 can enter the positioning groove 584, and it can be ensured that the corresponding molds 6 at the left and right ends can be in the same horizontal position after entering.

[0037] Reference Figure 2 - Figure 4 The top of the bottom plate 1 is fixedly connected to an outer push block 56 in the area inside the conveyor belt 4. The top view of the outer push block 56 is a rectangular right-angled trapezoid cut out of a triangle. The shape of the outer push block 56 is set to ensure that when the control block 55 contacts the oblique angle of the front end of the outer push block 56, it can move in the direction away from the control block 55, and the cut angle of the outer push block 56 is set on the inner side of the front end. The outer wall of the rotating rod 2 is rotatably connected to a support plate 7. The top of the support plate 7 contacts the bottom end of the mold 6. Through the setting of the support plate 7, the bottom end of the mold 6 has a supporting force. The outer wall of the rotating rod 2 on the upper and lower surfaces of the support plate 7 is provided with a protrusion larger than the diameter of the rotating rod 2. Through the setting of the protrusion, it is ensured that the support plate 7 is not easy to fall under the action of gravity during use. The inner wall of the support plate 7 is provided with a through hole matching the position of the rotating rod 2. A power slot 8 is opened inside the bottom plate 1. The inner wall of the power slot 8 is fixedly connected with a motor 9. The output shaft of the motor 9 is fixedly connected to the bottom end of the rotating rod 2.

[0038] Working principle: When in use, the staff starts the equipment, so that the motor 9 starts, so that the left conveyor belt 4 rotates counterclockwise, thereby driving the half of the left mold 6 close to the right side to move from front to back, and at the same time, the right conveyor belt 4 rotates clockwise, so that the half of the right mold 6 close to the left end also moves from front to back.

[0039] During the movement of the mold 6, it first changes from tilted to horizontal. When it just becomes horizontal, since the slide bar 53 is only subjected to the force of the spring 1 54, the slide bar 53 is at the end away from the other side mold 6, so the left end mold 6 is not in contact with the right end mold 6.

[0040] As the conveyor belt 4 is transported, when the control block 55 contacts the inclined surface of the push-out block 56, the control blocks 55 on both sides move toward each other under the control of the inclined surface of the push-out block 56. During the movement, the anti-deflection block 582 first moves toward the direction of entering the positioning groove 584. Since the end of the anti-deflection block 582 close to the positioning groove 584 is set at an angle, the anti-deflection block 582 can enter the positioning groove 584 more easily and can be adjusted in time when there is a small position deviation.

[0041] After the adjustment is completed, as the moving distance of the control block 55 increases, the dies 6 on both sides approach each other, thereby squeezing the pipe in the middle of the dies 6 on both sides and squeezing the surface of the pipe into shape, so that corrugations appear on the outer wall of the pipe, thereby forming the corrugated pipe.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
