IV. Main Spare Parts Technical Flow:
1. The plug welding working process of the front and rear rack, large arm, bucket etc as below:
1.1 The front and rear rack is the key part in the whole machine, so the quality is directly
related to the whole machine. The deformation of the rack will directly cause the other
parts of damage, even cause the whole machine scrap. Considering the machine quality
and working life, so the whole machine adopts the 460C alloy steel.
The technical flow:
Baiting- Bending Plaits- Connection and Alignment-Welding-Tempering (The tempering
temperature is 550~650 centigrade,elimination of the jointing stress and deformation )- Sand
Blasting- Bore a hole-Polishing and assemble with primer spray
1.2 The car adopts 460C alloy steel, the technical flow as above.
2. The Oil Cylinder Main Spare Parts Technical Flow:
2.1 The cylinder Barrel: welding oil mouth-honing, to ensure out-of-roundness of the cylinder
barrel
2.2 Piston Rod: Forging-Rough Turning-Hardening and Tempering-Finish Turning-Bore a
hole-Grinding-Hard Chrome Plating-Polished Finish
2.3 Pressure Test: The assemble oil cylinder through testing pressure and testing leak of
test-bed, after confirming everything is well then to be used. The testing pressure is 20Mpa
2.4 The oil cylinder seal adopts the combination seal.
3. The Main Shaft Parts Technical Flow:
Baiting-Rough Turning-Tempering-Finish Turing-Quenching-Grinding
The Material of front axle of big arm, rear axle of big arm, articulated in middle axle,lift, tipping
bucket and pin roll etc: 40Cr
4. All shaft sleeves are adopted lubricated oil copper bush.
