[0002] Seamless steel pipe is a kind of steel pipe with sophisticated manufacturing technology, which is characterized by no welds. It is made by perforating solid round steel billets and then hot rolling, cold drawing or cold rolling. Compared with welded steel pipes, seamless steel pipes have higher strength, pressure resistance and corrosion resistance, and are suitable for high pressure, high temperature and special use environment requirements. In order to adjust the diameter, wall thickness or length of the pipe to meet specific requirements and standards, a pipe shrinking machine may be used to help adjust the size and shape of the pipe, improve the quality of the pipe, improve the surface finish, and improve production efficiency.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a tube shrinking machine for seamless steel tube production, comprising a cabinet 1, a processing tube 2 is arranged on one side of the cabinet 1, an electric push rod 3 is arranged inside the processing tube 2, the output end of the electric push rod 3 is fixedly connected to a connecting plate 4, one side of the connecting plate 4 is fixedly connected to a rack 5, a rotating column 6 is rotatably connected inside the processing tube 2, and a gear 7 is fixedly connected to the outer wall of the rotating column 6, a limiting rod 8 is fixedly connected inside the processing tube 2, and the outer wall of the limiting rod 8 is slidably connected to a gear The rack 15 is meshed with the gear 7, the gear 7 is meshed with the rack 29, a push plate 10 is fixedly connected to one side of the rack 15, a shrink tube assembly is arranged on the top of the rack 29, the shrink tube assembly includes a connecting disk 11, the connecting disk 11 is fixedly connected to the top of the rack 15, a connecting plate 2 12 is slidably connected inside the connecting disk 11, a die-casting block 13 is fixedly connected to the top of the connecting plate 2, and the die-casting block 13 is slidably connected inside the processing tube 2;

[0031] Specifically, the precise action of starting the electric push rod 3 guides the connecting plate 4 to drive the rack 5 to move correctly, and the starting rack 5 pushes the gear 7 to rotate, so that the rack 29 moves in the opposite direction of the rack 5 under the constraint of the limit rod 8. As the rack 29 is pushed upward, the connecting disk 11 and the connecting plate 2 12 move synchronously to accurately adjust the position of the die-casting block 13 to ensure that the processing process of the steel pipe is stable and reliable. This automated design not only improves the processing efficiency and accuracy, but also ensures the consistency of product quality. After the operation is completed, the rack 29 begins to move downward, and the rack 5 guides the push plate 10 to move upward, so that the push plate 10 smoothly pushes the processed steel pipe out of the processing pipe 2, achieving the effect of efficient and automatic material withdrawal. The precise design of this set of automated devices provides reliable guarantee for the smooth progress of the production process, ensuring the dual guarantee of production efficiency and product quality.

[0032] Reference Figure 1 and Figure 4 A hydraulic push rod 14 is provided on the top of the cabinet 1, and a connecting plate 3 15 is fixedly connected to the output end of the hydraulic push rod 14, and a fixing plate 19 is fixedly connected to the bottom of the connecting plate 3 15, and a sliding column 16 is slidably connected inside the fixing plate 19, and a spring 17 is sleeved on the outer wall of the sliding column 16, and one end of the spring 17 is fixedly connected to the inside of the fixing plate 19, and the other end of the spring 17 is fixedly connected to a clamping plate 18, and the clamping plate 18 is fixedly connected to one end of the sliding column 16, and a limiting column 20 is slidably connected inside the fixing plate 19, and the limiting column 20 is fixedly connected to the inside of the cabinet 1;

[0033] Specifically, during the steel pipe processing, the hydraulic push rod 14 is adjusted to drive the connecting plate 3 15 and the fixing plate 19 to a suitable height under the restriction of the limit column 20. This precise adjustment process ensures the accuracy and stability of the steel pipe processing. When the steel pipe is inserted into the middle of the fixing plate 19, the steel pipe will be squeezed by the clamping plates 18 on both sides, which causes the clamping plates 18 to move to both sides under the restriction of the sliding column 16, and at the same time exerts a squeezing force on the spring 17. The reaction force generated by the reduction of the spring 17 enables the clamping plate 18 to exert just the right amount of force on the steel pipe, ensuring that the position of the steel pipe is stable and reliable, which not only ensures the stability and accuracy of the steel pipe during the processing, but also improves the processing efficiency and product quality.

[0034] Working principle: When the equipment is used to process the steel pipe, first according to the length of the steel pipe, the hydraulic push rod 14 is adjusted to drive the connecting plate 3 15 and the fixing plate 19 to a suitable height under the restriction of the limit column 20. At this time, the steel pipe is inserted into the middle of the fixing plate 19. At this time, the steel pipe will first squeeze the clamping plates 18 on both sides, so that the clamping plates 18 will move to both sides under the restriction of the sliding column 16, and at the same time generate a squeezing force on the spring 17. The reaction force generated by the reduction of the spring 17 allows the clamping plate 18 to apply a certain force to the steel pipe, thereby stabilizing the position of the steel pipe. At this time, the part of the steel pipe that needs to be processed will enter the processing pipe 2. When the electric push rod 3 is started, it pushes the connecting plate 14 to synchronously drive the rack 15 to move, so that the rack 15 makes the gear 7 start to rotate, and then the rack 29 is displaced in the opposite direction of the rack 5 under the restriction of the limit rod 8. When the rack 29 is pushed upward, the corresponding connecting plate 11 will also be displaced synchronously, and at the same time slide through the position of the connecting plate 2, so that the die-casting block 13 is gradually brought together under the restriction, so as to process the steel pipe. After the operation is completed, the rack 29 starts to move downward, so that the rack 15 drives the push plate 10 to move upward, so that the push plate 10 can push the processed steel pipe out of the processing pipe 2, so as to achieve the effect of automatic material withdrawal.

[0035] 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.
