Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan 华欣诚 introduce you to adjust pipe production equipment failure analysis and common pipe detuning: detuning is entirely a man-made phenomenon, as the roll forming uneven pressure on the same level. In the molding by the different pressure on both sides of the roller, the tube can be solved for some special plateau thus causing the deviation problem. After the sizing rollers slightly detuning can solve some of the joints and tubes do not turn round the problem, but the intensity of offset is too large, it will make the two do not match the cross-cutting equipment pass, leaving the wall to produce scratches. The upper and lower ends of the vertical roll the force should also be uniform cross-cutting equipment offer, if the vertical roll occurs when the upper and lower elevation, the same effect will destroy pass agreement, so that the wall appears scratched. Especially after the pass of R rounded sharpening severe degree of offset, the wall will be more severely scratched. At the same time the practice of offset, but also make more uneven wear pass the arc, resulting in poor circulation. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan 华欣诚 you resolve squeeze rollers scratches caused, mainly in the bottom of the tube, because the following points: (1) does not match the weld pass extruded structure with two-roll, three-roll and four-roll, as long as the combination of the hole do not match, it is likely to cause the tube surface scratches, two roll-type structure is particularly prominent. Factors hole has a lot do not fit to a two-roll structure, for example, such as bearing damage; roller axial movement; pass sample sizes; two roller height position is not the same; shaft bending and assembly of instability and so on. (2) match the height of the lower edge of the squeegee roller should pass highly consistent with the rolling line, while the height of the guide rollers is determined by the tube wall thickness. If the height of the cross-guide roller is reduced to a certain limit shear device manufacturer, squeeze roll groove edge fillet will cause scratches on the bottom of the tube, particularly in the extrusion roll groove fillet sharpening R After more prone to scratches. (3) lack of pressure especially squeeze squeeze two rollers squeeze roller device structure on a roll, when the transverse shear extrusion equipment is insufficient pressure in the tube with the tension, the rollers will appear on the elevation, so R grooved rounded protruding edge, resulting in a lower portion of the tube scratch. When the squeeze roll pass R rounded sharpening, will increase the occurrence of accidents scratch.
