Straightening / Brushin Steel Bar Making Machine , Worm And Gear Type
Instructions of machinery techniques
The single-armed pay-off stand, adopts two single-armed stands to work alternatively to facilitate connecting among wire rods and paying off.
Wire pack stand is cone-typed to the rod changing into loop-typed from linear-typed in case of line disordered.

Mechanical descaling machine:
Mechanical descaling machine consists of two sets of 90 degree bending rolls. According to the theoretical design, it ensures enough bending angle to strip maximum oxidized iron scale. It adjusts quickly so that electrical connector can go through smoothly via pneumatic mode. The totally-enclosed machine adds collection box at the bottom. Straightening part uses ball screw to adjust .
Drawing machine adopts single-drum horizontal drawing machine with a drawing drum of 900mm in diameter, no cooling water system. The motor is connected to the hard tooth cylindrical gears via belts, and the drawing drum, installed in the output shaft of the speed reducer, adopts expanded tube connection making it easily to install. After casting, processing and shaping, the surface of drum surfaces hard alloy. The AC motor adopts variable frequency control. The drawing drum is equipped with pneumatic tight roll to stop, when running it can lift automatically in case of disordering the line while stop.
The drawing die adopts double-die structure, while the two dies are forced to water cooling and the back die equipped with rotating driving system(initiatively)
The drawing motor is 90kw,while the speed reducer is 400 hard tooth speed reducer.
The rotating-die motor is 5.5kw.
The straightening machine is passive typed, consisting of two sets of 90 degree bending rolls while each set is 11 rolls, 5 rolls up and 6 rolls down. It straightens the steel bar via tension drawing by the tractor.
The active-typed brushing machine, driven by motors, consists of wire brushes to remove the impurities in the surface of steel bars.
The motor is 1.1kw and the speed reducer is planet-cycloid retarder typed.
There are two tractors. The first one is located in the front of quenching heating furnace while the second one is located behind the tempering cooling device functioning dragging all the line. The lower roll is in a single input axis and three output axis of non-standard transmission box. The upper roller is in the sliding slot of the upper frame, linked to the lower roll and with pneumatic cylinders controlling moving up and down, and the pressure can be adjusted and maintained to ensure the clamping force of the steel bars and make it works smoothly, to ensure constant tension in the controlling system. Traction roller, with a material of Gr12MoV (HRC58-62), is installed in optical axis via expanded tube to facilitate replacement of traction roller.
The motor is 11kw.
The speed reducer is planet-cycloid retarder typed.

Hydraulic reversing shear machine
According to the requirements of rapid shear production line, it shall ensure synchronous shearing and reversing and the normal continuous production.
The motor for hydraulic pressure station is 2.2 KW.
It is designed according to the requirements of paying-off of steel bars and the rotating speed of take-up drum can be changed regularly according to the speed of steel bars to realize wiring regularly.
Motor: 4KW
Reducer type: worm and gear type.
