Description

Technical Field

[0001] The utility model relates to the technical field of fluoroplastics products, in particular to a fluorine equidistant telescopic corrugated pipe and a shaping device thereof. Background Technique

[0002] The forming process of general fluoroplastic corrugated pipes is to carry out shaping processing on pipe materials. In order to achieve continuous shaping operations, they are usually designed as spiral corrugated pipes. There are two types of shaping. One is to heat through a spiral die, and then the pipe material is spirally inserted into the inner part of the pipe and matched with the spiral die outside the pipe for forming. The other is to heat through a spiral die, seal both ends of the pipe material and insert it into the spiral die, and use air pressure to blow and expand to form a spiral corrugated pipe. Because the spiral corrugated pipe itself has a certain spiral direction, there will be a phenomenon of offset spiral angle when bending. The spiral corrugated pipe has poor efficiency in local shaping and non-shaping of segmented straight parts. Poor matching between the spiral rod inserted spirally and the spiral die outside the pipe will cause poor waveform or uneven thickness. Content of the Utility Model

Detailed implementation mode

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings. Embodiment 1

[0025] Refer to Figures 1-6 , which is the first embodiment of the present utility model. This embodiment provides an embodiment of a fluorine equidistant telescopic bellows and its shaping device, including a frame 11, a protective cover 14 is fixedly arranged on the upper end surface of the frame 11, and a pipe 12 that can move left and right is arranged above the frame 11;

[0026] Four jogging rollers 13 are symmetrically arranged up and down on the left and right sides of the outer circumferential surface of the pipe 12 and are rotatable. A shaping cavity 19 that communicates left and right is arranged in the protective cover 14. Three die moving cavities 25 are arranged on the lower wall of the shaping cavity 19. A preheating fixing frame 22 is fixedly arranged on the left side of the upper end surface of the frame 11.

[0027] Two left heating dies 20 that can move back and forth are arranged in the protective cover 14.

[0028] Two middle heating dies 18 that can move back and forth are arranged on the right side of the left heating die 20.

[0029] Two cooling and shaping dies 17 that can move back and forth are arranged on the right side of the middle heating die 18. A cooling radiator 21 is fixedly arranged on the end surface of the cooling and shaping die 17 away from the pipe 12. The cooling radiator 21 can play a role in heat dissipation and cooling.

[0030] A heating coil 16 is rotatably arranged on the outer circumferential surface of the pipe 12 on the left side of the left heating die 20. The heating coil 16 can play a role in heating. The left end surface of the heating coil 16 is fixedly connected to the right end surface of the preheating fixing frame 22.

[0031] Four rotating motors 23 are fixedly arranged on the right side of the protective cover 14 and the left side of the preheating fixing frame 22. The front end surface of the jogging roller 13 is power-connected to the rotating motor 23 on the same side.

[0032] The formed pipe is clamped in parallel between four jogging rollers 13. The feeding distance for each time can be controlled by a PLC. At this time, the pipe 12 will first pass through the heating coil 16 for preheating the plastic softening point, and then pass through the two opposite left hot molds 20 and the middle hot mold 18. At this time, after the pipe 12 reaches the working temperature in the left hot mold 20 and the middle hot mold 18, the two rotating motors 23 on the left side are started to drive the jogging rollers 13 on the left side to rotate and convey at a fixed pitch. While the rotating motors 23 on the right side are not started, the pipe 12 will be expanded against the inner walls of the left hot mold 20 and the middle hot mold 18 due to conveying push and thermal expansion, completing the shaping of the first pitch. Embodiment 2

[0033] Refer to Figures 1-6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a mold rotating shaft 26 is rotatably provided in the mold moving cavity 25. A mold motor 24 is fixedly provided on a side wall of the mold moving cavity 25 away from the pipe 12. The outer circumferential surface of the mold rotating shaft 26 is threadedly connected to the left hot mold 20, the middle hot mold 18 and the cooling and shaping mold 17 on the same side.

[0034] A control panel 15 is fixedly provided on the front end surface of the protective cover 14. The control panel 15 can play a role in controlling the start and stop of all motors of the present invention.

[0035] Subsequently, the left hot mold 20, the middle hot mold 18 and the cooling and shaping mold 17 that can be opened and closed back and forth are synchronously opened. The jogging rollers 13 on both the left and right sides rotate and convey the pipes with the same pitch at the same time. The pipe 12 that has been shaped in the left hot mold 20 cavity enters the middle hot mold 18, and the above-mentioned pipe 12 is preheated and shaped with equal pitch for repeated operations until the pipe 12 enters the cooling and shaping mold 17 for shaping. In this way, the pipe 12 with equal-distance expansion can be obtained through sequential forming operations; if no shaping is performed in a certain section of the working process, only the alternating rotation of the jogging rollers 13 is used to convey the pipe 12 to the next working distance.

[0036] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
