Coil Straightener Shear end and Welder

MAY SHUAY-established as a provider of engineering and technical services for the steel pipe and tube industry, saw tube & pipe makers' growing requests of setting up complete tube mill plants. Based on solving their various needs for different machines, we designed this Coil Straightener Shear end and Welder. It's obviously to see it's a multifunctional machine which combines straighten, shear end and welder of coils. All different machine functions are controlled by unitary systematic methods. Below are descriptions of this Coil Straightener Shear end and Welder.

◆ Uncoiler
Coil infeed plates move to uncoil through plate track, and then they will be raised to position by oil hydraulic. Until two holding roller sets enter to fixed coil section, then they will be put into leveling section by motor power. After all actions are completed, then loosen clutch of the motor to keep the holding rollers maintain idle state. It can avoid two motors to pull each other.

◆ Leveling Section
Steels enter to leveling section through high/low holder arms, after leveling by leveling roller set, and then they enter welding & shearing section. The roller is driven by oil hydraulic.

◆ Shearing Section
The enter/exit side boards were driven by oil hydraulic. After both work-pieces were put into the position, they will be clamped right away, then welding and shearing will be finished. Clamping boards can make left/right movement to facilitate the sheared work-piece automatic positioning.

◆ Welding Process
The mobile way of electronic arc is adopting DC motor to drive the linear system and make accuracy movement of welding torch. It could reduce melt-through at the edges of work-piece effetely.

• ◆ Two-sides leveling roller
  It will increase uncoiling difficulties if the coil is too winding. However, it will be solved through the leveling roller with inch-adjustment to ensure good straight quality.
  
  ◆ Hydraulic power
  Even coil’s thickness is larger than normal ones, but they also can be levered by hydraulic power system.
  
  ◆ Coil-Guide Plate
  The best advantage of coil-guide plate is labor-saving due to it make hold manually become useless.
  
  ◆ Clamp copper
  Controlled by DC Motor, it can be adjusted according to operator’s request.
  
  ◆ Bottom weld cylinder
  Bottom weld cylinder is below machine welding area. Coil can be hold stable to prevent over weld damages happen.
  
  ◆ Side roller
  Side rollers are both installed at machine beginning and end position. The purpose is to make workpiece unmovable.
