Seamless welding technology for square tubes
The seamless welding technology for square tubes has shown excellent performance in square tube welding, improved the precision and finish of pipe fittings, and overcome the shortcomings of seams that affect the appearance during welding. It can effectively eliminate the welds, intersections and parting lines of pipe fittings. The key to this process is the use of advanced technology and vertical machining centers, which can produce molds in a completely new way. At the same time, efficient heating and refrigeration cycle technology is used during the forming process. The characteristics of seamless welding technology of square tube manufacturers are as follows:
(I) In previous production, the cooling pipeline was arranged near the surface of the square tube, and the surface finish was always uneven. In some newer processes, by setting the water flow of the core and cavity cooling pipelines near the injection area, the quality of the square tube produced can be better guaranteed;
(II) The emergence of seamless welding technology makes it possible to change the channel design and use polyhedron vertical machining center milling. In the actual molding process, changes in channel design can help control the optimal temperature changes for heating and cooling of square tubes;
(iii) The application of seamless welding technology will not cause warping and deformation of square tubes, nor will it cause any problems with the matching of the mold cavity and the mold on the side of the core. Since the workpiece can be tilted, it avoids the use of only ball milling cutters for end face processing, which extends the service life of the milling cutter;
(iv) Square tube manufacturers use seamless welding technology, which can not only help eliminate mold welds, but also correspondingly improve the accuracy, finish and appearance of square tubes;
(v) The seamless welding technology of square tube manufacturers can keep temperature fluctuations within 60°C by milling important mid-diameter penetration chambers. These penetration chambers are milled behind the mold cavity, and their shape is consistent with the mold cavity. They can serve as channels for high-pressure steam and cooling water, and can play a role in heat conduction on the surface of the mold cavity, making the temperature distribution more uniform, thereby maintaining temperature changes and controlling the temperature fluctuation rate;
