This machine is between shear welder and host (forming sizing mill) ,use for after a roll of strip steel are used up, before the next roll strip since prepared from uncoiling, shearing and butt welding time to ensure that the host (forming sizing mill) continuous production and store enough strip steel.
This unit is main include in press & carry material device, accumulator assemble, carry off material unit, electric control unit:
(１) press & carry material device:It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press & carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.
(2)Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.
(3)Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.

The forming & sizing unit is the vital equipment to the pipe mill line. This unit abide by the roll frame theory. It could continue process some specification steel tube by no-contact welding, that is carrying some strip steel to this unit and let it passing the frame roll to frame tube raw, and then take the electric fluid together on the tube welding surface so as to treat the tube temperature higher to suit welding by the pressing roll welding, and then after cooling, forming sizing and flattener to product what is your demand tube.

Upper pipe → align → chain transport to the water pressure center → clamp → fixed and mobile end test head extends to seal both ends of the steel pipe → low-pressure water fills with water, exhausts → closes the water filling valve and exhaust valve → pressurizes → Protects pressure→Relieve pressure→Retract the fixed and mobile end test head→Clamp loose→Send the steel pipe out of the chain→empty water→discharge
This machine is used to collect, stack steel pipe into 6 or 4 angles, and bundle automatically. It runs stably without manual operation. Meanwhile, eliminate the noise and knocking of shock of steel pipes. Our packing line can improve your pipes quality and production efficiency, reduce cost, as well as eliminate potential safety hazard.
