Brief Discussion on Processing Technology of Welded Pipe Machine
Release time:
2018-12-06 11:56
First of all, to understand the processing technology of welded pipe roll machine, we must first understand the quenching process. After rough turning and semi-finishing turning, the roll should be quenched and tempered at low temperature before finishing turning. Quenching is to change the microstructure of the roll, change the spherical pearlite after withdrawal into tempered martensite and a small amount of retained austenite, and improve the surface hardness and wear resistance of the roll. Obtain sufficient strength and toughness; Prolong service life of rolls.

Secondly, the more common water bucket roller is chrome plated. In the printing process, the ink on the water roller will also be transferred to the water-channeling roller and the water bucket roller, thus reducing its water transfer. In addition, when the downtime is long, even if the water bucket roller and the ink roller are not contaminated with ink, the original hydrophilic properties of the roller are changed due to the formation of an oxide film on the surface and the adsorption of oil mist dust and other debris in the air on the roller surface.
Finally, according to the law of strip steel deformation, we choose edge bending forming method, double radius bending combination forming method, W reverse bending forming method, row roller straight edge forming method. In the aspect of pass design, computer aided design and simulation analysis of rolling deformation are used to optimize the roll design.
Jiangsu Nanyang Machinery Manufacturing Co., Ltd. produces: ZG series high-frequency welded pipe unit, GW series cold bending forming unit, BG series stainless steel pipe making unit, FG high-precision composite pipe production line, roll mold.
