Description

Automatic milling production line for longitudinal seams of pipe body Technical Field The utility model relates to an automatic milling production line for longitudinal joints of a pipe body, and belongs to the technical field of longitudinal joint milling of large-sized pipes. Background The large-scale pipe is widely applied to the fields of construction, industrial manufacture, municipal engineering and energy, and the pipe comprises plastics, metals, concrete and the like according to material distinction. For large-scale metal pipe, the welding operation of pipe molding needs to be carried out, the pipe is curled into a tubular structure by a plate, the welding operation needs to be carried out on the longitudinal joint spliced by the plate, and the longitudinal joint is expanded as an opening due to the fact that the plate has a certain thickness and is large in size, and the welding quality and the welding stability can be influenced by the opening expansion structure. Therefore, before the plates are curled into a tubular structure, groove forming needs to be carried out on two end faces of the spliced plates, butt joint can be carried out on the spliced joints in a regular manner after the grooves are formed, but due to the fact that the diameter and the wall thickness of a tubular structure are large, welding after the spliced joints are directly carried out cannot meet welding firmness, welding seam milling of certain specifications needs to be carried out on the inner side and the outer side of the spliced joints, welding operation is convenient and welding area is improved, welding of the inner side and the outer side is carried out step by step, relative splicing tolerance of the inner side is small and operation is easy, therefore, pre-welding of the inner side welding seam is carried out firstly, welding of the outer side welding seam is carried out, in the welding process of the inner side welding seam, the influence of butt joint position, welding temperature and the like can be carried out, certain flatness deformation difference exists on the outer side welding seam, and therefore welding seam milling of the outer side spliced seam needs to be carried out based on the inner side welding seam after the pre-welding of the inner side welding seam. The welding seam milling is generally carried out by adopting a manual or linear cutting device, the preformed pipe body is large in volume and weight, so that the welding seam milling forming is difficult, the traditional pipe longitudinal seam welding equipment is realized by adopting the displacement of the pipe through a milling end, but the displacement driving of a large pipe cannot be realized, in addition, the side of a spliced seam is exposed, the linear displacement of the milling equipment is adopted, the stress uniformity of the pipe is poor, the deformation of the spliced seam is irregular, the roundness of the pipe is difficult to ensure, the relative position degree of the milling equipment and the spliced seam is difficult to ensure, and the product quality cannot be controlled.
