Abstract

The invention discloses a three-piece roller for calendering of a weld, and relates to processing equipment. The three-piece roller specifically comprises a mounting rack, hydraulic rods and a mounting plate, two ends of the bottom surface of the mounting plate are respectively and fixedly connected with the top ends of the vertically-mounted hydraulic rods, the bottom ends of the hydraulic rods are respectively and fixedly connected with two ends of the mounting rack, and a pipeline needing to be calendered is arranged at the bottom of the mounting rack. According to the roller, the weld calendering technology adopting the three-piece type roller is adopted, and redundant solder at the weld is extruded out and protrudes on the outer wall of the pipeline so that the influence on the sealing performance of the weld of the pipeline can be effectively avoided when the solder is cleaned, and the smoothness of the surface of the pipeline is guaranteed.

Description

technical field [0001] The invention relates to a processing device, in particular to a three-piece roller for rolling seams. Background technique [0002] Welding is a commonly used processing method to permanently bond two objects together. The existing large-diameter pipes are made of 304 stainless steel or 316 stainless steel or carbon steel. There is a weld seam on the large-diameter pipes. In order to ensure The inner and outer walls of large-diameter pipes are smooth, and the weld seams need to be removed. [0003] However, in the prior art, when processing pipes of different specifications, it is necessary to replace the entire calendering roller, which is very inconvenient to use, and the excess solder after calendering is irregularly distributed on both sides of the weld, and it is also very difficult to clean. Big. Contents of the invention [0004] The purpose of the present invention is to provide a three-piece roller for seam calendering, so as to solve the...
