[0002] Steel pipe is a steel material with a hollow cross section, whose length is much greater than its diameter or circumference. According to the material, it is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; according to the purpose, it is divided into steel pipe for pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling and high-pressure equipment.

[0003] When the ends of a round steel pipe are spliced, it is usually necessary to perform a shrinking process on the ends of the steel pipe to facilitate the splicing operation, and the shrinking process of the steel pipe is usually performed on a shrinking machine. A traditional shrinking machine usually includes a shrinking cylinder with a movable end and an abutment seat at the other end, and a placement seat and a clamping seat that can move up and down provided between the shrinking cylinder and the abutment seat. The steel pipe is positioned by the cooperation of the clamping seat and the placement seat.

[0004] The above structure can only perform shrinkage treatment on one end of the steel pipe during use, and cannot perform selective and synchronous shrinkage operation on both ends of the steel pipe as needed, which reduces the use scope of the device; and when positioning the steel pipe before shrinking, the clamping seat is moved downward and adjusted to make the steel pipe tightly abut against the placement groove. In this way, after the shrinkage is completed, the steel pipe is easily stuck on the inner wall of the placement groove, causing inconvenience in taking out and reducing the use efficiency of the device. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the two ends of the steel pipe cannot be selectively and synchronously contracted as required, and it is inconvenient to take out the steel pipe, which reduces the application scope of the device.

[0007] A right mounting seat is symmetrically fixed at the other end of the top surface of the operating table, and a right hydraulic cylinder is provided on the right mounting seat. A right shrinking tube is fixed on the movable end of the right hydraulic cylinder, and a detachable end cover is also provided on the right shrinking tube. An adjusting device for lifting the steel pipe is also provided on the operating table near the left end of the placement seat.

[0008] Furthermore, a cylinder body is fixedly sleeved on the outer side surface of the right shrinking cylinder end and an internal thread is provided on the inner wall of the cylinder body, and a threaded cylinder matching the internal thread is fixedly provided on the end surface of the end cover.

[0009] Furthermore, the adjusting device includes a lifting seat and an electric push rod. A lifting seat that can move up and down is provided on the operating table near the left end of the placement seat. A mounting groove is opened in the operating table corresponding to the middle of the lifting seat. An electric push rod is fixed on the bottom wall of the mounting groove. The movable end of the electric push rod is fixedly connected to the bottom surface of the lifting seat through a connecting rod.

[0010] Furthermore, a cavity is opened in the operating table corresponding to the two ends of the lifting seat, and a moving rod that can slide up and down is passed through the cavity. The end of the moving rod extending out of the top surface of the operating table is fixedly connected to the bottom surface of the lifting seat, and a limit seat is fixedly provided on the bottom surface of the moving rod, and a buffer spring is wound between the limit seat and the top wall of the cavity.

[0011] Furthermore, the end of the top surface of the lifting seat is an arc-shaped structure.

[0012] The advantages of the utility model compared with the existing technology are:

[0022] Embodiment 1

[0023] like Figure 1 As shown, a high-hardness steel pipe forming equipment comprises an operating table 1 and a supporting column 2 on the bottom surface of the operating table 1, a placing seat 3 is fixedly provided in the middle position of the top surface of the operating table 1, and a clamping seat 4 which can move up and down is provided on the placing seat 3, and the steel pipe is positioned by the up and down movement of the clamping seat 4 and the cooperation of the placing seat 3, and a left mounting seat 5 is fixedly provided at one end of the top surface of the operating table 1 corresponding to the placing seat 3, and a left hydraulic cylinder 6 is provided on the left mounting seat 5, and a left shrinking tube 7 is fixedly provided at the movable end of the left hydraulic cylinder 6, and the left shrinking tube 7 is driven to move rightward by the extension of the left hydraulic cylinder 6, so that the left end of the steel pipe is shrinked, and the above-mentioned features belong to the prior art;

[0024] A right mounting seat 8 is symmetrically fixed at the other end of the top surface of the operating table 1, and a right hydraulic cylinder 9 is arranged on the right mounting seat 8. A right shrinking tube 10 is fixedly arranged at the movable end of the right hydraulic cylinder 9, and a detachable end cover 11 is also provided on the right shrinking tube 10. When the end cover 11 is installed, the right side end of the steel pipe can be abutted. When the end cover 11 is removed, the elongation of the right hydraulic cylinder 9 is controlled, and the left and right ends of the steel pipe can be shrinked synchronously. In this way, the right side end of the steel pipe can be selectively non-shrinked or shrunken as needed, thereby improving the use range of the device. An adjusting device for jacking up the steel pipe is also provided on the operating table 1 near the left end of the placement seat 3.

[0025] like Figure 2 and Figure 3As shown, a cylinder body 12 is fixedly sleeved on the outer side of the end of the right shrinking cylinder 10 and an internal thread 13 is opened on the inner wall of the cylinder body 12. A threaded cylinder 14 matched with the internal thread 13 is fixed on the end face of the end cover 11. With the cooperation of the threaded cylinder 14 and the internal thread 13, the end cover 11 is detachably connected.

[0026] Embodiment 2

[0027] Based on the first embodiment, Figure 4 and Figure 5 As shown, the specific structure of the regulating device is as follows:

[0028] The adjusting device includes a lifting seat 15 and an electric push rod 17. A lifting seat 15 that can move up and down is provided on the operating table 1 near the left end of the placement seat 3. A mounting groove 16 is opened in the operating table 1 corresponding to the middle of the lifting seat 15. An electric push rod 17 is fixedly provided on the bottom wall of the mounting groove 16. The movable end of the electric push rod 17 is fixedly connected to the bottom surface of the lifting seat 15 through a connecting rod. The extension and retraction of the electric push rod 17 is controlled to drive the lifting seat 15 to move up and down, and the steel pipe after the shrinkage treatment is lifted up, thereby facilitating the removal of the steel pipe and improving the use efficiency of the device.

[0029] A cavity 18 is provided in the operating table 1 corresponding to the two ends of the lifting seat 15, and a moving rod 19 which can slide up and down is passed through the cavity 18. The end of the moving rod 19 extending out of the top surface of the operating table 1 is fixedly connected to the bottom surface of the lifting seat 15, and a limit seat 20 is fixedly provided on the bottom surface of the moving rod 19, and a buffer spring 21 is wound between the limit seat 20 and the top wall of the cavity 18. Under the action of the moving rod 19 and the buffer spring 21, the lifting seat 15 can be adjusted up and down in a buffered manner, thereby avoiding a strong lifting force on the steel pipe.

[0030] The top end of the lifting seat 15 is an arc-shaped structure, and when the lifting seat 15 is at the lowest position, the left shrinking tube 7 can pass through the arc-shaped structure to move left and right.

[0031] In specific use, firstly, the end cover 11 is installed or disassembled according to the need to shrink one or both ends of the steel pipe. When shrinking one end of the steel pipe, the end cover 11 is fixedly connected to the right shrinking tube 10, and the steel pipe is placed in the placement seat 3. By controlling the downward movement of the clamping seat 4, the steel pipe is positioned. Finally, the extension of the left hydraulic cylinder 6 is controlled to drive the left shrinking tube 7 to move rightward, and the left end of the steel pipe is shrunken. After the shrinking is completed, the clamping seat 4 is moved upward, and then the extension of the electric push rod 17 is controlled to drive the lifting seat 15 to move upward. At the same time, under the action of the moving rod 19 and the buffer spring 21, the steel pipe is buffered and lifted up, so as to facilitate the removal of the steel pipe.

[0032] When it is necessary to perform synchronous shrinking treatment on the two ends of the steel pipe, the end cover 11 is removed, and the left shrinking tube 7 and the right shrinking tube 10 are driven to move synchronously to the right by controlling the synchronous extension of the left hydraulic cylinder 6 and the right hydraulic cylinder 9, so as to perform synchronous shrinking treatment on the left and right ends of the steel pipe, thereby improving the scope of use of the device.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
