ZTZG's Round Pipe Making Machine Without Changing Rollers: For producing ordinary carbon steel pipes, the roughing and finishing rollers before welding are shared. The sizing section uses a quick-change worktable and hydraulic quick-release device, allowing for rapid changes in sizing dimensions. When changing to different round pipe specifications, there's no need to disassemble and change rollers. For producing stainless steel pipes or low-carbon steel pipes using submerged arc welding, due to the slower welding speed, the entire production line can operate without changing rollers. This means that rollers are shared across the entire production line for different pipe specifications, and online electric adjustment is possible. Highly suitable for manufacturers producing multiple specifications in small batches of round pipes!

ZTZG's new direct-forming, roller-share tube-making machine is suitable for producing medium to large-sized square and rectangular tubes ranging from 200 to 500 square meters. It is a fully automated welded pipe production line that requires no roller changes. It can produce square and rectangular tubes of different specifications, with the rollers driven by a motor allowing for online adjustment and modification of production specifications. This significantly reduces rollere costs and improves production efficiency. The mechanized adjustment precision is higher, resulting in more regular tube shapes. Manufacturers of large-diameter square and rectangular tubes for building structures, industrial machinery, and transportation should definitely learn about ZTZG's automated, mold-free square tube equipment!

This ZTZG's jointly developed, designed, and manufactured "Round-to-Square Tube Production Line Without Roller Change" can produce round tubes, square tubes, and rectangular tubes without requiring roller changes. When producing round tubes of different specifications, the rough forming and fine forming rollers before welding are shared. When producing square and rectangular tubes within a certain range, no roller changes are needed in the forming section before welding;The sizing section adopts a misalignment adjustment method, allowing online adjustments to produce different specifications of square and rectangular tubes. This significantly reduces roller costs, improves production efficiency, and greatly enhances economic benefits for tube manufacturers!

When producing square rectangular tubes, a direct square forming method is used, and the product form is a square rectangular tube during welding. The mold does not need to be replaced, only needs to be electrically adjusted online. In order to make the square tube more beautiful, Zhongtai creatively designed a diagonal insertion roller structure. The diagonal insertion roller is a structure that penetrates deep into the steel pipe to prevent deformation of the R angle, and controls the internal control of the steel pipe R angle. Adding a reverse bending device to the sizing to prevent steel pipe rebound, especially suitable for high-strength steel products.

The Zhongtai Round Square Changing and Not Changing Mold Unit is most suitable for customers with a large number of square and rectangular specifications. It uses the frame (or sliding sleeve) to stay relatively stationary with the roller and slide on the roller shaft to achieve mold opening and closing, thus achieving the effect of not changing the mold. When changing production specifications, compared with traditional round to square units, it saves a lot of mold investment, improves efficiency, increases production, reduces labor intensity, and no longer requires manual disassembly and assembly of molds.
