Description

[0002] Cold rolling: hot-rolled steel coils are used as raw materials, and after pickling to remove the oxide scale, cold rolling is carried out. The finished product is a hard rolled coil. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the hard rolled coil increase, and the toughness and plasticity index decrease. Therefore, the stamping performance will deteriorate and it can only be used for parts with simple deformation.

The corresponding roller shaft 2 has a side plate 3 which is sleeved on the liquid inlet pipe 5 and the liquid outlet pipe 6. The ends of the liquid inlet pipe 5 and the liquid outlet pipe 6 pass through the roller shaft 2. The roller body 1 and the side plate 3 are pre-fixed and connected by positioning parts. The cooling component cools down the roller body 1 to prevent it from deformation. The cooling component is easy to disassemble and clean to avoid dirt remaining on its inner wall and affecting the heat dissipation efficiency.
