压力加工设备(国外英文资料) 1, the original parts of the rolling machine: the power of the supply execution part; Drive part: the movement form and energy of the original moving part as required for the work part. The execution part: the metal completes the plastic deformation. 2, the role of the work seat and the parts of each unit: Roll: the core component of metal plastic deformation in rolling form. Roller bearing: to support roll and position. Roll adjustment device: adjust the position of the roll and fix it after adjustment to ensure the required deformation. Machine frame: the adjustment device and the guide device for installation and fixing roll, roll bearing, roll. Roller guide device: to guide the rolling pieces in and out of the roll with the right and smooth direction. A: it is used to set the frame on the foundation. 3, the mark of a rolling mill: Blank section: the diameter of the diameter of the helical wheel; Strip mill: roll length; Steel tube rolling mill: it is made out of steel tube diameter (continuous cold rolling mill with no head rolling). 4, why dont cold rolled steel sheet using cast iron roll: 】 【 because D after determine the modulus of elasticity is inversely proportional to the minimum thickness, the smaller the elastic modulus, the greater the minimum thickness = 0.5 E E iron steel in order to guarantee the minimum thickness should be forged steel rolling mill. The roll is the core part of the mill that is directly in contact with the rolling piece, which forces the metal to produce plastic deformation. 6, the load on roll rolling: the friction load, the mechanical load, the heat load. 7, the failure form of roll: wear and break. Process requirements and life requirements of roll roll: The process requirements: to ensure the quality and production of the required rolling materials, the roll has reasonable structure, size and material. (2) life requirements: roll too early or not is not normal damage, failure, requirements for this roll has requir
