Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a processing equipment for long-length, variable-wall-thickness seamless steel pipes. Background Technology

[0002] Long-length variable wall thickness seamless steel pipe is a type of seamless steel pipe with a relatively long single length. Its wall thickness varies continuously or in segments along the axial direction. A gradual wall thickness transition zone is formed at one end of the billet through a high-pressure spinning technique (e.g., reducing from 20mm to 10mm) to avoid stress concentration caused by abrupt changes in wall thickness. The steel pipe adopts segmented rolling and plasma welding processes to connect pipe segments with different wall thicknesses. After the whole pipe is solution treated to eliminate welding stress, it is finally ensured to be defect-free through non-destructive testing. Due to its length, this type of steel pipe requires more material and is therefore heavier, making it more inconvenient to transfer between different processing stations. Utility Model Content

[0003] The purpose of this invention is to provide a processing equipment for long-length, variable-wall-thickness seamless steel pipes to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a processing equipment for long-length, variable-wall-thickness seamless steel pipes, comprising;

[0005] The steel pipe body has a positioning component on its outer side, which includes a steel pipe positioning frame, a support frame, a clamping plate, and a positioning rod.

[0006] There are two steel pipe positioning frames and multiple support frames. The steel pipe positioning frames are hexagonal in structure. Each steel pipe positioning frame has an integrally fixed sleeve A at its corner. There are multiple positioning rods. The two ends of the positioning rods pass through the sleeves A on the two steel pipe positioning frames and are slidably connected to them.

[0007] There are multiple support frames. One end of the support frame is fitted onto the outside of the steel pipe positioning frame and rotatably connected to it. The other end of the support frame is hinged. The outside of the clamping plate is fixedly connected. The clamping plate is arc-shaped. Multiple clamping plates are enclosed to form a ring around the outside of the steel pipe body.

[0008] Preferably, a threaded tube A is fitted on the outer side of the sleeve A, and an external thread is provided on the outer side of the positioning rod. One end of the threaded tube A is rotatably connected to the sleeve A, and the other end of the threaded tube A is fitted on the outer side of the positioning rod and threadedly connected to it. The position of the positioning rod can be adjusted by rotating the threaded tube A. The number of steel pipe positioning frames can be expanded according to the length of the steel pipe body, thereby providing multi-segment support.

[0009] Preferably, the positioning rod has a limiting component, which includes a connecting part, a telescopic rod A, a locking tube, a telescopic tube B, and a push rod;

[0010] One end of the connecting part is fitted onto the outside of the positioning rod and slidably connected to it. The other end of the connecting part is hinged to the telescopic rod A. The telescopic rod A has a hollow structure inside. The telescopic tube B is embedded inside the telescopic rod A and slidably connected to it. The locking tube is fitted onto the connection between the telescopic tube B and the telescopic rod A. The locking tube has a spring pin. The spring pin is inserted into the inside of the telescopic tube B to lock and limit the movement. The push rod is located at one end of the telescopic tube B. Both ends of the push rod are inserted into the inside of the two support frames.

[0011] Preferably, the connecting part has an integrally fixed sleeve B, which is sleeved on the outside of the positioning rod. One end of the sleeve B has a threaded tube B, which is rotatably connected. The other end of the threaded tube B is sleeved on the outside of the positioning rod and threadedly connected to it. By rotating the threaded tube B, the position of the connecting part on the positioning rod can be adjusted, so that the push rod pushes the support frame to tighten, and so that the clamping plate is tightened on the outer wall of the steel pipe body.

[0012] Preferably, the bottom of the steel pipe positioning frame has a base, and the two ends of the base are welded and fixed to two steel pipe positioning frames respectively. The bottom of the base has multiple pulleys, which can push the steel pipe body to move, thereby transferring it between different work stations and improving work efficiency.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Place the steel pipe body between the two support frames and manually press the support frames to make the clamps fit against the outer wall of the steel pipe body. At this time, push the steel pipe body to one end to reduce the gap between the two clamps. The steel pipe body is tightened by friction. Then push the rotating threaded pipe B to make the connecting part slide on the positioning rod, so that the push rod presses the support frame, so that the clamps are continuously tightened, and the steel pipe body is limited and fixed.

[0015] The position of the positioning rod can be adjusted by rotating the threaded tube A. The number of steel pipe positioning frames can be expanded according to the length of the steel pipe body, so as to provide multi-section support and limit the diameter of different parts of the steel pipe.

[0016] The steel pipe body can be moved by pulleys, and then transferred between different work stations, thereby improving work efficiency. Attached Figure Description
