Multiple-type Flying  shears for wire rod production line

1.Brief Introduction to Flying Shear:

the function of the flying shear:
1, as the head and rear part of the rolling parts have some defect or the temperature of steel is too low, the flying shear needs to cut the head and rear to ensure the quality of the rolling parts before it gets into the finishing mill.
2, the flying shear will cut the rolling parts immediately if any failure occurs to the finishing mill, then the switch will turn the parts to snap shear to snap.

3.Performance features:
Flying shear is composed of transmission equipment, cutting support base and upper & lower spindle. Rotary tool rest has installed backsword, two spindles which are parallel with start-stop work system. Tool rest makes one revolution to finish one cutting period. the motor drives the spindle through reduction gears and makes the upper, lower spindle rotated through the gear.

the lower spindle is connected with transmission equipment. Motor adapt separately ventilated machine and equipped speed measuring motor to measure the speed of the direct motor. Safety gear coupling is installed between the motor and reduction gears to ensure the safety to use the equipment.

Cutting support base is a welded case with four-layers, it has four gear rolls inside, including upper, lower spindle and the others are transition gear rolls

Upper spindle has optical-electricityencoder to control the start-stop position of the shear blade in the processing of the cutting.

Lubrication:
Recycled lubrication is adopted for internal gear and bearing of the shearing machine with dilute oil supplied by outside dilute oil station. Sump lubrication is applied for redactor.
