Process Flow.
1). Process flow of hydraulic piston rod.
Connecting rod using 35 steel, processing technology: cold-drawn forming a turning a continuous medium frequency induction hardening, a cylindrical grinding, a fine grinding cylindrical a fine grinding cylindrical shearing section.at finishing a plating chromium to hydrogen tempering shearing section.at fine grinding.In order to improve the surface quality and corrosion resistance of piston rod, super finishing process was added before chrome plating.
2). Piston rod plating process.
Inspection before plating - pack hanging fixture - chemical degreasing, electric lift oil - water - activation pickling - water washing- the moment, the piston rod chromium plating, recycling water - water washing - unloading hanging fixture - inspection
Manufacturing process description:
1. Hydraulic shear cutting
2. CNC machining + additional broaching and milling operations
3. Induction hardening at a range of different frequencies and powers
4. Rotary straightening
5. Proportionally servo controlled CNC grinding
6. Leading edge technologies for hard chromium,
7. Dehydrogenation and tempering
8. Wet polish and superfinish polish with 100% surface condition control
9. Export Packaging
Packing Of Piston Rod
Each rod will be oil treatment first , then separate by layer and layer , one by one .
Each small box use VCI bag to protect from rust , then box into wooden pallet .
The weight and size can be made according to customer requirement .
