The squeeze roller stand is a five-roller structure, the bottom roller is a cylindrical roller, and the height of the roller seat after repairing the roller is adjusted by adding a cushion.Two side stand rollers, bearing mounted inside the roll, double support type roll seat, the openings of the stand rollers on both sides are adjusted by two motors respectively.The upper roller is equipped with 2 sets. The upper roller is raised and lowered separately and adjusted separately. Electric adjustment is adopted.The extrusion roller adopts closed structure, and the position of different specifications can be adjusted.Side roll inward tilt 1 degree, side roll in the premise of meeting the strength as small as possible.
The stand is double knife,Use alternately or at the same time, do not stop to replace the cutter
Outer scrap: double planer type, with burr winding device;Planer lifting using hydraulic cylinder, can quickly lift and up and down fine tuning;External burr knife can be adjusted horizontally to the operation;A lower supporting roller device is provided.
Weld surface flattening action, two roller type, passive, the height of the lower roller through adding pad adjustment, change the product specifications without changing the roller.
Function:Cool the steel tube to room temperature for further rolling and straightening into the shaping section.Add waterproof cover.
Finish product to proper shape and straighten.
The shaping unit is composed of four staggered axes, with both upper and lower shaft being active. Two dc 160KW motors are respectively driven by reducer, gear box and universal shaft, and the rollers are staggered
Cut the running steel tube into the following runout table.
When the continuous working rolling mill delivers the steel pipe to the flying saw, the saw car tracks and synchronizes with the pipe speed, the clamp block clamps, and the two saw cutting systems installed on the rotary table with the saw blade rotation, which makes radial feed under the drive of the feed ac servo motor.At this time, the rotary table is also rotating, and the saw cutting system makes compound movement between the rotary table and its own feed, and cuts the steel pipe along the section shape track of the cut piece.Then the systems relax back into place and wait for the next working cycle.The cutting feed use polar coordinates type.
