Example Embodiment
[0070] Example 1
[0071] In such Figure 5 For the catheter shown in, the specification of the catheter tube is Φ110×2.0mm, the length of the straight section at the A end is 400mm, the length of the straight section at the B end is 100mm, and the bending part is a right-angle bend with a bending radius of R200.
[0072] A clamping device suitable for welding of elbows. The device mainly includes a rotating disc, a supporting mechanism, an adapter, a pipe clamp ring, bolts and other connecting parts, such as Figure 4 Shown.
[0073] The rotating disc is a disc with a diameter of Φ500mm and a thickness of 30mm. There is a boss with a diameter of Φ50mm and a height of 100mm on the back of the disc. The boss is clamped by a three-jaw chuck on a conventional welding positioner to realize the rotating disc and welding. The positioner is installed and fixed, and the welding positioner can be turned on during the welding process to realize the rotation of the rotating disc with the main ...
Example Embodiment
[0087] Example 2
[0088] Such as Image 6 The catheter shown in the specification of the catheter tube is Φ110×2.0mm, the length of the straight section of the A end is 400mm, the bending part is a right-angle bend with a bending radius of R200, and the straight section of the B end is 100mm in length and is connected in the middle of the flange 1 compensator, the size of the butt joint between the compensator and the pipe and flange is Φ109×1.5mm, and the inner diameter of the butt joint is the same.
[0089] The clamping device for elbow welding and clamping is exactly the same as that of the first embodiment. The steps of using the bending pipe welding and clamping device for pipe clamping and welding include:
[0090] (1) Prepare a conventional welding positioner. The welding positioner directly clamps the flange of the pipe end A to complete the welding of the circumferential seam between the pipe and the flange, and the welding positioner directly clamps the flange of the pipe...
Example Embodiment
[0100] Example 3
[0101] Such as Figure 7 The pipe shown in the pipe is welded by two ends of the pipe and two flanges. The specification of the pipe is Φ110×2.0mm. The length of the straight section of end A of the left end of the pipe is 400mm and the length of the straight section of end B is 100mm, curved The part is a bend with a bending radius of R200 and a bending angle of 45°; the length of the straight line at the C end of the pipe at the right end is 100mm and the length of the straight end at the D end is 400mm, and the bending part is a bend with a bending radius of R200 and a bending angle of 45°. Angle; The connection between the pipe and the pipe is a short straight section B and a straight section C directly welded, and the weld is not on the straight section at the end of the pipe.
[0102] The clamping device for elbow welding and clamping is exactly the same as that in Example 1. The steps of using the elbow welding and clamping device for pipe clamping and wel...
