High frequency steel Square weld pipe mill Making Machine

The three-high rolling mill requires a lifting platform or turning guide plate, as well as various special turning machines, steel moving machines, reverse enclosing discs, forward enclosing discs, standing enclosing discs and other devices.
The function of the rewinding plate is to guide the flat oval, diamond, and rectangular rolling pieces to the next stand, and turn the 90-degree angle to make the rolling pieces stand upright into the square hole or vertical rolling hole. The rolling piece in the running trough of the enclosure cannot naturally complete the above-mentioned turning action, and must rely on the twisting pipe.
The function of the positive encircling plate is to guide the standing square rolling piece from one rolling mill to another rolling mill, and make the rolling piece naturally turn over a 45-degree angle and flatly enter the oval pass.
The function of the standing wall is to guide the rolled pieces of the upper rolling line to the lower rolling line on the same stand, and twist the rolled pieces at an angle of 45 degrees. Some rolling mills for the production of welded tube billets also use a standing wall, which only serves as a guide and does not have the effect of twisting the rolled piece.

The utility model belongs to the technical field of steel pipe processing, and specifically relates to a new type of steel pipe rolling mill. Mechanism; wherein the rolling mechanism includes: a mandrel, at least two matching arc-shaped compression blocks and corresponding hydraulic cylinders that are sheathed on the mandrel; each hydraulic cylinder is suitable for driving the corresponding arc-shaped compression blocks inward Pressing to form a rolling barrel to squeeze the steel pipe between the rolling barrel and the mandrel; the control module is adapted to control the drive locking mechanism to lock the mandrel, and the traction mechanism to pull the steel pipe through the rolling barrel , To roll the steel pipe; the displacement detection device is suitable for detecting the rolled length of the steel pipe; and when the rolled length of the steel pipe is equal to the set value of the control module, the control module controls the new type of steel pipe rolling mill to stop working.

Product Description

HGF300 high-frequency welded pipe production line is the special equipment providing longitudinally welded pipe and cold formed steel for industries such as metallurgy, construction, transportation, machinery, vehicles and so on. Used traditional square technology to produce square and rectangle pipe.Taking cold or hot-rolled steel as raw materials, through cold-formed and high-frequency welding method to produce the suitable round tube. Material of the coil: low carbon steel (σb500Mpas235Mpa.)Strip Steel: Q235 (max.)

Finished product will be of round pipe, square and rectangle pipe.
