Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy spiral welded pipe processing, in particular to a cutting device for aluminum alloy spiral welded pipes. Background Art
[0002] Compared with pipes processed by turning, boring, etc., welded pipes have the advantages of simple production process, high production efficiency, and less waste, which makes welded pipes widely used. According to the direction of the weld, it is divided into straight seam welded pipe and spiral welded pipe. Straight seam welded pipe is a pipe obtained by rolling the plate of aluminum alloy structure or low carbon carbon structure into a tube billet in a direction perpendicular to the width of the plate, and then welding the gap of the tube billet through welding equipment. Spiral welded pipe is a pipe made by rolling the steel strip of aluminum alloy structure or low carbon carbon structure into a tube billet at a certain spiral angle, and then welding the tube billet seam. Compared with straight seam welded pipe, spiral welded pipe can produce pipes of different diameters using the same width of strip steel. For large-scale pipeline construction projects such as power transmission and oil transportation, it is difficult to produce pipelines that meet the requirements using the straight seam pipeline process. Since spiral welded pipes need to be welded according to spiral lines during the production process, the welding direction of the welds of spiral welded pipes is not a simple vertical or parallel relationship. For this reason, spiral welded pipes exhibit stronger compressive and tensile properties. Among them, threaded welded pipes made of aluminum alloy have the characteristics of strong corrosion resistance, light weight, and low transportation cost, so that aluminum alloy spiral welded pipes can be widely used in the construction of large-scale pipelines such as power transmission and oil transportation.
[0003] In the production process of aluminum alloy spiral welded pipes, the semi-finished products of aluminum alloy spiral welded pipes are all long pipes, which are much longer than the actual required length. At this time, the whole aluminum alloy spiral welded pipe needs to be cut, that is, the aluminum alloy spiral welded pipe needs to be cut into a required length. Therefore, in the production process of aluminum alloy spiral welded pipes, cutting equipment is required to cut the aluminum alloy spiral welded pipes. In order to facilitate the processing needs of rolling aluminum alloy spiral welded pipes into pipe billets and welding, the processing process of aluminum alloy spiral welded pipes needs to keep the threaded pipe rotating. To this end, if the end of the aluminum alloy spiral welded pipe is clamped and fixed, the rotation of the aluminum alloy spiral welded pipe needs to be turned off first. Repeatedly starting and stopping the rotation of the aluminum alloy spiral welded pipe is very troublesome. However, if the aluminum alloy spiral welded pipe is cut directly, the end of the aluminum alloy spiral welded pipe is difficult to clamp and fix, resulting in a lack of force support points at the end of the aluminum alloy spiral welded pipe, causing the end of the aluminum alloy spiral welded pipe to be suspended and tilted, resulting in the front end of the aluminum alloy spiral welded pipe being high and the rear end being low. For this reason, the aluminum alloy spiral welded pipe cut by the cutting blade has some deviation, which reduces the stability of the device. In addition, after the aluminum alloy spiral welded pipe is cut, it is necessary to remove the aluminum alloy spiral welded pipe from the cutting equipment. The current method is that workers operate handling tools to carry the cut aluminum alloy spiral welded pipe. Since the cut aluminum alloy spiral welded pipe is located on the cutting station of the cutting equipment, it is necessary to move the cut aluminum alloy spiral welded pipe out of the cutting station before the cutting process of the aluminum alloy spiral welded pipe can be carried out again. In order to facilitate the continuous cutting of the aluminum alloy spiral welded pipe, it is necessary to arrange a special person to keep an eye on the handling operation. Therefore, the cutting process requires more personnel. Therefore, there is room for improvement in the cutting process of aluminum alloy spiral welded pipes, starting from the perspective of improving cutting quality and cutting efficiency, so as to improve the quality and processing efficiency of aluminum alloy spiral welded pipes.
