[0028] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Combination Figures 1 to 5 As shown, a seamless steel pipe shrinking machine provided by the utility model includes a shrinking mechanism 1, a conveyor belt 2 and a baffle 3.

[0032] Combination Figures 1 to 5 As shown, the shrinking mechanism 1 performs reciprocating motion to shrink the seamless steel pipe; the width of the conveyor belt 2 is smaller than the length of the seamless steel pipe, and the seamless steel pipe is placed horizontally on the conveyor belt 2; the baffle 3 is located on the side of the conveyor belt 2 away from the shrinking mechanism 1, and the baffle 3 fits one side end face of the seamless steel pipe. The seamless steel pipe shrinking machine conveys the seamless steel pipe to the specified position through the conveyor belt 2, and then further positions the seamless steel pipe through the design of the baffle 3, determines the position of the seamless steel pipe, and through the design of the width of the conveyor belt 2, the shrinking section of the seamless steel pipe is suspended in the air, so that the movable shrinking mechanism 1 can shrink the seamless steel pipes in turn.

[0033] In some embodiments, in combination Figure 1 As shown, the seamless steel pipe shrinking machine also includes a baffle hydraulic cylinder 31, the driving end of the baffle hydraulic cylinder 31 is fixedly connected to the baffle 3, and the movement direction of the baffle hydraulic cylinder 31 is the same as the axial direction of the seamless steel pipe. The position of the baffle 3 is controlled by the baffle hydraulic cylinder 31, and the seamless steel pipe biased towards the direction of the baffle 3 can be pushed to the specified position. At the same time, when the conveyor belt 2 is conveying seamless steel pipes of different lengths, the air length of the shrinking section can still be guaranteed.

[0034] In some embodiments, in combination Figure 1As shown, the seamless steel pipe shrinking machine also includes a steel pipe positioning wheel 32, which is fixedly connected to the baffle 3. The steel pipe positioning wheels 32 are used in pairs, and each pair of steel pipe positioning wheels 32 is distributed up and down. The outer contour surface of the steel pipe positioning wheel 32 fits the seamless steel pipe. One end of the seamless steel pipe can be fixed to the baffle 3 through the steel pipe positioning wheel 32 to prevent the seamless steel pipe from being offset and unable to rest against the baffle 3. At the same time, the fixing method will not extend new actions, reducing the complexity of the structure.

[0035] In some embodiments, in combination Figure 1 As shown, the baffle 3 also includes a soft gasket 33, and the soft gasket 33 is fixed on the surface of the baffle 3 that is in contact with the seamless steel pipe. By adding the soft gasket 33, the damage to the seamless steel pipe when the seamless steel pipe abuts against the baffle 3 can be reduced. At the same time, the soft gasket 33 can effectively prevent the seamless steel pipe from rebounding during the abutting process.

[0036] In some embodiments, in combination Figure 1 As shown, it also includes a shrinking base 11 and a guide rail 12. The shrinking base 11 is fixedly connected to the shrinking mechanism 1. The shrinking base 11 is slidably assembled on the guide rail 12. The shrinking base 11 is a platform for installing the shrinking mechanism 1. The reciprocating motion of the shrinking mechanism 1 can be achieved by sliding the shrinking base 11 on the guide rail 12. Based on this motion, the shrinking processing can be achieved by controlling the start and stop of the shrinking mechanism 1.

[0037] In some embodiments, in combination Figure 1 As shown, the seamless steel pipe shrinking machine also includes an electric hydraulic push rod 13, the driving end of the electric hydraulic push rod 13 is fixedly connected to the shrinking base 11, and the fixed end of the electric hydraulic push rod 13 is slidably assembled on the guide rail 12. The establishment of the electric hydraulic push rod 13 can adjust the vertical height of the shrinking mechanism 1, thereby increasing the applicability of the shrinking mechanism 1.

[0038] In some embodiments, in combination Figure 1 As shown, at least two shrinking mechanisms 1 are horizontally fixedly connected to the shrinking base 11. By connecting multiple shrinking mechanisms 1 to the shrinking base 11, the number of seamless steel pipes shrunken in a single action can be increased, thereby improving the efficiency of the shrinking process.

[0039] In some embodiments, in combination Figure 1As shown, seamless steel pipe positioning grooves 21 are evenly arranged on the conveyor belt 2, and the spacing distance between the seamless steel pipe positioning grooves 21 is greater than the width of the head shrinking mechanism 1. The design of the seamless steel pipe positioning grooves 21 can effectively prevent the seamless steel pipe from rotating on the conveyor belt 2, improve the accuracy of docking during the head shrinking process, and improve the stability of the head shrinking process. At the same time, controlling the spacing of the seamless steel pipe positioning grooves 21 can prevent the head shrinking mechanism 1 from interfering with the unprocessed seamless steel pipe during the head shrinking process, causing the unprocessed seamless steel pipe to deviate, thereby affecting the head shrinking process.

[0040] In some embodiments, in combination Figure 1 As shown, the seamless steel pipe positioning grooves 21 evenly opened on the conveyor belt 2 are composed of continuous V-shaped surfaces, and the number and spacing of the V-shaped surfaces are the same as the number and spacing of the shrinking mechanism 1. By designing the appearance of the seamless steel pipe positioning grooves 21, it is possible to ensure that in a single processing sequence, the relative position of a single or multiple seamless steel pipes and the shrinking mechanism 1 is precisely controlled, which is an important factor for the stable and high-speed operation of the seamless steel pipe shrinking machine.

[0041] In some embodiments, in combination Figure 1 As shown, the seamless steel pipe shrinking machine also includes a fixing component 4, which includes a pressing block 41 and a pressing block hydraulic cylinder 42. The pressing block 41 is located above the conveyor belt 2, and the lower surface of the pressing block 41 fits the seamless steel pipe. The upper surface of the pressing block 41 is fixedly connected to the driving end of the vertically set pressing block hydraulic cylinder 42. The seamless steel pipe that has been shrunk is fixed by the fixing component 4, which can effectively avoid the adhesion between the seamless steel pipe and the shrinking mechanism 1, thereby improving the stability of the continuous shrinking process.

[0042] Working process: the seamless steel pipe passes through the shrinking mechanism 1 in sequence under the conveyance of the conveyor belt 2; when the seamless steel pipe is facing the shrinking mechanism 1, the shrinking mechanism 1 moves toward the seamless steel pipe, and the seamless steel pipe enters the shrinking hole of the shrinking mechanism 1 under the action of the baffle 3, and the shrinking process begins; after the shrinking process is completed, the seamless steel pipe is fixed by the fixing component 4, the shrinking mechanism 1 returns to the initial position, and then the fixing component 4 is lifted, the shrunken seamless steel pipe moves backward, and the new seamless steel pipe passes through the shrinking mechanism 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
