Quick details of machine
1. Gearbox
Transmission gear: Parallel tri-axial structure is combination of reduction and matrix. The gear is made of high quality alloy. It had been treated by cementation heat process, the precision grade can reach6th. It guarantees the tooth surface is high speed, overloading, low noise and high torque.
Drive bearing: The brand of axletree: NSK.
Lubrication: Gear bearings in the gear box will be of oil immersed. There is hydraulic lubrication in the gear engagement and gear bearings.
Cooling: Lubricated cooling adopts shell and tube cooler and circulated water cooling method.
2. Screw & Barrel
Diameter:￠71mm
L/D:40:1
Direction of rotation: Co-rotating
Screw & elements: 38CrMoAlA, surface nitrogen treated, HV = 950 ~ 1100. Using special CNC grinding machine for screw, after dedicated grinding, its curve fit and surface finish is much better than screw elements treated by conventional processing method
Core axle: High quality alloy steel 40CrNiMo that with high tenacity and durability. It had been treated by the hardening and tempering process.
1). Diameter: ￠71.8mm 2). Structure: The first section works for main feeding, the fifth section is set up for venting naturally, and the ninth section is set up for vacuum venting and others are blocked. 3). Material: 38CrMoAlA, surface nitrogen treated, HV = 950 ~ 1100.
4). Heating: Adopt multiple step format electric heating. The first and the second zone and the machine head zone are cast copper heater and others are cast aluminum heater. The total heating power is 60kw and the max heating capacity every section can reach 500℃.
5). Cooling: Adopt soft water cooling system in the barrel and tap water cooling way outside barrel. The circulation pipes are made of stainless steel and the water inflow regulating valves are stainless valves.
The brand of electromagnetic valve is DANFOSS.
6) Length:290*10=2900mm
