A Band Sawing Machine Design And Research For Aluminum Processing

In the modern industry,aluminum is irreplaceable,because aluminum is a light metal,aluminum profile is now widely used,especially in the field of machinery,construction and aviation industry.Electrolytic aluminum industry in China develops gradually from the 30 s to the 2001,the original aluminum production capacity reached about 4300000 tons,ranking first in the world.The original aluminum production reached about 13000000 tons in 2009,experiencing a glut.With the development of electrolytic aluminum technology,the groove of the electrolytic cell is more and more larger,and the biggest groove in the world is the 600kA electrolytic cell which is produced in China.The increase of electrolyzer groove brings greater difficulty in aluminum project construction.Generally electrolytic tank columns of busbar processing which are below 240kA using vertical band saw.As a result of the basic changes in the form of 400kA column bus connection,vertical band saw could no longer meet the needs of the construction site for processing.Aim at above problems,according to the actual needs of electrolytic aluminum project,applied to a vertical band sawing machine in order to meet the processing requirements of the 400kA column aluminum bus bar.In this passage,I mainly completed the following work:(1)Make full use of field condition,reform the vertical band sawing machine into a horizontal band sawing machine.Design the guide device,saw frame device,blade bracket mechanism and working table etc.(2)Give up the drive system of the vertical band saw,redesign the drive system of the modified horizontal band sawing machine.Adopts the way that Motor drive pulley,makes sure of the type of drive motor,pulley,synchronous belt after calculation.(3)Adopt the original hydraulic system of vertical band saw,using this system for used for horizontal band saw table drive.According to the new working conditions,check the pressure cylinder,oil pump,motor,etc.Determine the hydraulic system of oil and other components of the system.Other components of the hydraulic system and other components of the system are determined.(4)Using electrical operating system to controls the modified horizontal band sawing machine.The completion of the transformation of band sawing machine through engineering practice,the cutting rate reached 130cm2/min,meet the processing requirements of 400kA electrolytic tank column bus.Not only guarantees the processing quality,but also saves the cost of the construction.
