Technical parameters and configuration of equipment
1. Main specifications of XK-450:
1.1 Model: XK- φ 450 X1200
1.2 Type: overall splicing
1.3 One time feeding amount: 50~60
1.4 Main motor: 55-6 energy-saving AC motor
1.5 Roller speed ratio: (front: rear) 1:1.29
1.6 Roller linear speed: before (design value): 28.6 m/min
Detailed specifications:
2.1 Roller group:
2.1.1 Type: front roll is of peripheral drilling type, and rear roll is of hollow type. 1 each
2.1.2 Material: alloy chilled cast iron (LTG-H), which is subject to precision grinding after tempering.
2.1.3 Hardness of working surface: HS: 70 ± 2
2.1.4 Strong springs shall be installed between the bearing pedestals on both sides of the roller, which will spring with the electric distance adjustment, effectively avoiding the gap between the distance adjustment screw and the roller and preventing collisions. 2 groups
2.1.5 Double row self-aligning roller bearing is adopted. (Origin: Wafangdian) Group 4
2.1.6 The bearing seat is made of cast iron (FC30) after tempering. The lubricating oil hole shall be attached. 4 groups
2.1.7 The bearing seat cover is made of iron and attached with labyrinth ring oil seal, and there is no oil leakage inside and outside. 4 groups
2.1.8 Rotary joint for roller heating and cooling is attached with stainless steel metal hose. 2 groups
2.1.9 Pneumatic cutter: stable, safe and convenient.                      1
2.2 Base and rack
2.2.1 The substructure is welded with H-shaped steel, tempered and machined. 1
2.2.2 The frame is welded with H-shaped steel and processed after tempering treatment, 2 groups
2.2.3 One stainless steel bowl
2.3 Roller gap adjustment device
2.3.1 Adjustment range: 0.4~15mm
2.3.2 It is composed of hydraulic pump and oil cylinder.
2.3.3 Distance adjustment mode: hydraulic distance adjustment
2.3.4 Electrical control: linkage, single action and inching can be realized to make the distance between two ends of the roller consistent during adjustment.
2.3.5 Distance adjustment specification: oil cylinder is used for distance adjustment on each side, which is stable, safe and not prone to failure. The distance display adopts a digital display distance meter, which is installed on the power distribution cabinet to effectively check the distance between the rods, and a limit switch is installed at the limit position of the distance adjustment, so as to ensure that the distance between the rollers is always within the specified range during the distance adjustment process and prevent the phenomenon of "hitting the rod".    
2.4 Rubber baffle group: hydraulic rubber baffle
2.4.1 Distance adjustment mode: hydraulic distance adjustment and electrical control can realize linkage and single action.
2.4.2 Distance adjustment range: 150~1500mm
2.4.3 It is composed of hydraulic pump, motor, oil cylinder, fixed guide rod and MC nylon baffle
2.4.4 The transmission base and nylon plate base are welded with high-quality SS41
2.4.5 The rubber baffle shall be installed twice to effectively prevent the rubber from entering between the roller bearing blocks.
2.5 Transmission mechanism:
2.5.1 Main motor: 6-level energy-saving AC motor, 1 set at 740rpm
2.5.2 Reduction gear box: SK (XK) 450, single input, double output, closed oil immersed hard gear reducer. Noise ≤ 78dB, safety factor: SA ≥ 2 times.        
2.5.3 Reducer gearbox and motor coupling: elastic sleeve pin coupling. 1 group
2.5.4 Reduction gear box and roller coupling: double shaft universal joint coupling.
