A little knowledge of trimmers

For the understanding of the longitudinal shear we are still very little, through the collection and sorting, the following to introduce the relevant knowledge of the longitudinal shear for your reference. The first thing we have to know is what are the components of it? Longitudinal shear balancing machine is divided into three parts: mechanical part, electric control part and electric measurement part. The three parts perform their respective functions, coordinate work and are indispensable. The mechanical part is also called mechanical bridge frame, with the general horizontal dynamic balance for example, the bottom of the balancing machine bed is placed on the basis of balancing machine components and stable equipment, shear cold bending steel equipment by the left and right two swing frame through the roller or V-shaped frame support rotor, rotor rotation conditions. The rotor is rotated by dragging the belt or coupling, and the vibration signals are converted into electrical signals by the sensors installed in the two swing frames, which are transmitted to the electrical measuring part. The mechanical part also includes auxiliary components such as the axial stop frame and safety frame (hood). The longitudinal shear mechanical and electrical control part is to control the start and stop of the motor and speed regulating parts, also known as the electric control box (cabinet). The electronic control part is divided into DC control and AC control, and ac control is divided into two speed AC control and frequency conversion AC control. The electric control part and the mechanical part of the balancing machine are integrated into one. The electrical measuring part is an electronic measuring system, also known as the electrical measuring box or indicator, which filters the electrical signal from the sensor, and compares it with the speed signal as a reference, showing the balance speed and unbalance of the measured rotor. The functions of the electrical measuring part also include plane separation and calibration. Next in about the characteristics and functions of the longitudinal shear balancing machine: the longitudinal shear balancing machine drag the rotor drive mode has the ring belt drag, coupling drag and self-drive. Ring belt drag is the use of rubber ring belt or silk ring belt, by the motor pulley drag the rotor, so the surface of the ring belt drag rotor must have a smooth cylindrical surface, the advantages of ring belt drag is not affected by the rotor unbalance, high balance accuracy. Coupling drag is the use of universal joint to balance the machine spindle and rotor connected. Coupling drag characteristic is suitable for rotor of irregular appearance, straight seam welded pipe can transfer bigger torque, suitable for fan high wind resistance of the rotor, such as drag drag the disadvantages of the coupling is the unbalance of coupling itself affect the rotor (slitting machine steel prices so coupling to balance before use), will also introduce interference affecting the precision of the equilibrium, in addition to do a lot of connection plate to adapt to the different models of the rotor. Self-actuation is the use of the rotor's own dynamic rotation. Self-drive is a type of drag that has little influence on the balance precision. The balance precision can be high, but only special rotors allowed by the structure can use this type of drag. Through the above introduction to the slitter, we have a more detailed understanding of it, I hope it can help in the future work.
