Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal pipe processing, in particular to a tool for rounding the cylinder sections of an over-limit container cylinder. Background Art
[0002] An over-limit pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. It is generally a tubular metal container. In the manufacture of containers, each container is composed of multiple cylinder segments, and the cylinder segments need to be rounded after welding. When the cylinder segments are hoisted onto the plate rolling machine for rounding, when the cylinder segments come into contact with the two lower rods of the plate rolling machine, the cross-section of the cylinder segments undergoes irregular and elliptical deformation due to its own weight, making it impossible for the plate rolling machine to operate and complete the rounding and rounding tasks of the cylinder segments.
[0003] The utility model patent with application number CN202223208533.8 discloses an auxiliary tooling for rounding the cylinder section of an over-limit container cylinder, including two side plates, each of which is welded with a lifting lug, a central axis is slidably connected in the two side plates, a main roller is installed on the outside of the central axis through a bearing, a rotating shaft is slidably connected in the two side plates, a secondary roller is installed on the outside of the rotating shaft through a bearing, and a quick-release mechanism is provided on the side plates. The utility model is provided with two side plates, a central axis and two rotating shafts are provided between the two side plates, the main roller is installed on the outside of the central axis through a bearing, and the secondary roller is installed on the outside of the rotating shaft through a bearing, so that the main roller and the secondary roller are in contact with the inner wall of the cylinder section to be corrected at the same time, and all of them are subjected to force during hoisting, the force-bearing area of the inner wall of the cylinder section is large, and the cylinder section will not produce local angular deformation.
[0004] The above technology installs the center shaft and the rotating shaft on the side plate, and then hoists the cylinder segment to the plate rolling machine for rounding. Due to multiple contact points in this process, the cylinder segment is well compressed and the probability of deformation is reduced. However, when rounding cylinder segments of different diameters, if the fixed-size side plates of the above technology are used for construction, the rotating shaft will not be able to make good contact with cylinder segments of different sizes, that is, the multi-point force design cannot be completed. Therefore, it is usually necessary to involve multiple tooling for cylinder segments of different sizes. This process is time-consuming and laborious, and it will also accumulate more tooling equipment. First, an adjustable rounding tooling is needed to adapt to the rounding work of cylinder segments of different sizes. Utility Model Content
[0005] The utility model provides a cylinder section rounding tool for an over-limit container cylinder body, which can solve the problem that a rounding auxiliary tool for a side plate of a fixed size cannot be adapted to the rounding of cylinder sections of different sizes.
[0006] In order to solve the above technical problems, the present application provides the following technical solutions: an over-limit container cylinder section rounding tool, comprising:
[0007] Two first-step shafts: the two first-step shafts are arranged opposite to each other;
[0008] Main shaft: the main shaft is coaxially arranged between the two first step shafts and is rotationally connected with the first step shafts;
[0009] Two second step shafts: coaxially fixedly connected with the first step shaft, and respectively arranged on the side of the two first step shafts away from the main shaft;
[0010] Two lifting blocks: the lifting blocks are respectively fixed on a side of the second step shaft away from the first step shaft;
[0011] Two lifting ears: the lifting ears are respectively fixed on the upper ends of the two lifting blocks;
[0012] First rotating block: one side of the first rotating block is annular and is rotatably connected to one of the first stepped shafts;
[0013] Second rotating block: one side of the second rotating block is annular and is rotatably connected to the second stepped shaft adjacent to the first rotating block;
[0014] Fourth rotating block: one side of the fourth rotating block is annular and is rotatably connected to another first-step shaft;
[0015] The third rotating block: one side of the third rotating block is annular and is rotatably connected to the second stepped shaft adjacent to the fourth rotating block;
[0016] First auxiliary shaft: two sides of the first auxiliary shaft are rotatably connected to the other side of the first rotating block and the other side of the third rotating block respectively;
[0017] Second auxiliary shaft: two sides of the second auxiliary shaft are rotatably connected to the other side of the first rotating block and the other side of the fourth rotating block respectively.
[0018] The basic principle and beneficial effects of this solution: This solution is modified on the basis of the original side panel design, by setting the first auxiliary shaft to be driven by the first rotating block and the third rotating block, and the second auxiliary shaft to be driven by the second rotating block and the fourth rotating block respectively; so that the positions of the first auxiliary shaft and the second auxiliary shaft can be rotated relative to the main shaft, that is, after being rotated into place, the positions of the first auxiliary shaft and the second auxiliary shaft are locked, so as to adapt to the rounding work of the cylinder section under the current size. When it is necessary to calibrate the rounding tooling of other sizes, the rotation angle of the first auxiliary shaft and the second auxiliary shaft can also be adjusted to complete the work adaptation;
[0019] Compared with the simple roller bar, when the cylinder segment is lifted for rounding, the force is applied in a straight line, which can easily cause local angular deformation of the cylinder segment. This causes local convex deformation of the cross section of the cylinder segment. When assembling the entire unit with the adjacent cylinder segment, it is impossible to assemble without external force due to the excessive edges and corners. It can only be forcibly assembled using tooling such as jacks, which ultimately leads to excessive stress in the local weld of the container cylinder. During the welding process, the weld is prone to cracks and other defects, which poses a serious hidden danger after the container is put into use. This solution still uses multi-point contact with the inner wall of the cylinder segment to achieve multi-point force and balance the pressure of the cylinder segment. At the same time, through the rotation adjustment of the first auxiliary shaft and the second auxiliary shaft, it can also adapt to more cylinder segments of different sizes for rounding.
[0020] Furthermore, it also includes an interval stepped shaft, which is fixedly arranged between the first stepped shaft and the second stepped shaft, and the interval stepped shaft is coaxial with the first stepped shaft.
[0021] Beneficial effect: It prevents interference between the rotating blocks on the first step shaft and the second step shaft when they rotate.
[0022] The spaced stepped shaft is protruded downwardly and provided with an extension block; the extension block is provided with an adjusting device for pushing the first rotating block, the second rotating block, the third rotating block and the fourth rotating block.
[0023] Beneficial effect: It is convenient to adjust the angles of the first auxiliary axis and the second auxiliary axis.
[0024] Furthermore, the first rotating block and the third rotating block rotate synchronously, and the second rotating block and the fourth rotating block rotate synchronously.
[0025] Furthermore, the adjusting device is a compression spring.
[0026] Beneficial effect: under the action of the reset force, the compression spring can push the first auxiliary shaft and the second auxiliary shaft to the contact position with the inner wall of the cylinder section; that is, the step of manually controlling the angle is omitted.
[0027] Furthermore, the adjustment device is a plurality of electric telescopic rods corresponding to and controlling four rotating blocks, the base of the electric telescopic rod is fixed to the extension block, and the free ends of the electric telescopic rod are respectively hinged to the four rotating blocks.
[0028] Beneficial effect: Electric control is adopted, which is more precise. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Compared with the simple roller bar, when the cylinder segment is lifted for rounding, the force is applied in a straight line, which can easily cause local angular deformation of the cylinder segment. This causes local convex deformation of the cross section of the cylinder segment. When assembling the entire unit with the adjacent cylinder segment, it is impossible to assemble without using external force due to the excessive edges and corners. It can only be forcibly assembled using tooling such as jacks, which ultimately leads to excessive stress in the local weld of the container cylinder. During the welding process, the weld is prone to cracks and other defects, which poses a serious hidden danger after the container is put into use. This solution still uses a multi-point contact with the inner wall of the cylinder segment to achieve multi-point force and balance the pressure of the cylinder segment. At the same time, through the rotation adjustment of the first auxiliary shaft 2 and the second auxiliary shaft 3, it can also adapt to more cylinder segments of different sizes for rounding.
