[0030] Usage method and working principle of this device: During use, when it is necessary to bend and roll the inner barrel of the washing machine, first pass one end of the stainless steel material through the heating box 4 and the auxiliary roller 3 and send it to a suitable position. Then, under the operation of the staff, rotate the threaded lead screw 23 to drive the fixed plate 22 to move, so as to fix one end of the stainless steel material to the outer wall of the forming shaft 17. And under the action of the spring inside the limiting device 24, drive the limiting rod to be inserted into the threaded lead screw 23, so as to fix and limit the threaded lead screw 23 to prevent the stainless steel material from loosening during bending and rolling.

And in cooperation with the auxiliary shaft 10, the stainless steel material is bent and formed. When the stainless steel is bent and formed, through the continuous rotation of the forming shaft 17, continuous shaping can be carried out on the stainless steel inner barrel to improve its quality. When the inner barrel of the washing machine is completed with bending and shaping, the second motor 19 stops working, so that the forming shaft 17 stops rotating.
