[0017] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0018] like Figure 1-2As shown, this embodiment provides a stainless steel welded pipe weld seam leveling device, including a support 1, a first weld seam rolling roller 2, a second weld seam rolling roller 3, and an in-pipe rolling roller 4. The first weld seam rolling roller 2 is installed on the support 1; the second weld seam rolling roller 3 is installed on the support 1, and the second weld seam rolling roller 3 is correspondingly arranged with the first weld seam rolling roller 2; the in-pipe rolling roller 4 is installed on the support 1, and the in-pipe rolling roller 4 is located between the first weld seam rolling roller 2 and the second weld seam rolling roller 3.
[0019] In some preferred embodiments of this utility model, the bracket 1 includes a frame 1a, a first mounting bracket 1b, a second mounting bracket 1c, and an adjusting screw 1d. The first mounting bracket 1b is mounted on the frame 1a, and the first weld seam rolling wheel 2 is mounted on the first mounting bracket 1b. The frame 1a is provided with an adjusting groove and an adjusting hole. The second mounting bracket 1c is slidably mounted on the adjusting groove, and the second weld seam rolling wheel 3 is mounted on the second mounting bracket 1c. The adjusting screw 1d is threadedly connected to the adjusting hole, and one end of the adjusting screw 1d is connected to the second mounting bracket 1c through a bearing. Rotating the adjusting screw 1d causes the second mounting bracket 1c to slide along the adjusting groove, thereby adjusting the distance between the second weld seam rolling wheel 3 and the first weld seam rolling wheel 2.
[0020] In some preferred embodiments of this utility model, the bracket 1 further includes a connecting arm 1e, one end of which is installed on the frame 1a, and the other end of which is connected to the inner tube rolling wheel 4.
[0021] In some preferred embodiments of this utility model, a cooling pipe 5 is further included. The cooling pipe 5 is arranged along the connecting arm 1e, and one end of the cooling pipe is correspondingly arranged with the inner roller 4. Thus, the cooling pipe 5 can be connected to external equipment and can be circulated with cooling circulating water or argon gas. The cooling circulating water can quickly cool the inner roller 4, thereby cooling the weld and allowing it to quickly pass through the heat-sensitive zone, preventing the weld from developing a chromium-depleted zone and thus avoiding corrosion failure. The introduction of argon gas fills the stainless steel with argon gas, thereby protecting the stainless steel weld and preventing rust and intergranular corrosion.
[0022] In some preferred embodiments of this utility model, the support 1 further includes an adjusting frame 1f, a first adjusting rod 1g, and a second adjusting rod 1h. The adjusting frame 1f is installed on the frame body 1a, and the first adjusting rod 1g is slidably installed on the adjusting frame 1f. One end of the second adjusting rod 1h is connected to the frame body 1a, and the other end of the second adjusting rod 1h is connected to the adjusting frame 1f. The second adjusting rod 1h and the first adjusting rod 1g are arranged perpendicular to each other. The connecting arm 1e is connected to the first adjusting rod 1g. Thus, the connecting arm 1e can be adjusted by the first adjusting rod 1g and the second adjusting rod 1h, thereby realizing the position adjustment of the inner tube rolling wheel 4.
[0023] In some preferred embodiments of this utility model, a welding torch holder 6 is also included, which is mounted on the bracket 1. Thus, the welding torch holder 6 can be used to mount an external welding torch. After the welding torch welds the stainless steel pipe, before the weld has completely cooled, the weld is hot-rolled and rapidly cooled, allowing the stainless steel weld to quickly pass through the heat-sensitive zone, reducing carbide precipitation, and thereby improving the quality of the welded pipe.
[0024] In some preferred embodiments of this utility model, the welding torch holder 6 includes a first adjusting motor 6a, a second adjusting motor 6b, a third adjusting motor 6c, a first adjusting lead screw 6d, a second adjusting lead screw 6e, a third adjusting lead screw 6f, a first lead screw nut 6g, a second lead screw nut 6h, a third lead screw nut 6i, a first support frame 6j, a second support frame 6k, and a third support frame 6l.
