Production process of shackle:
The traditional production process (2) is: blanking → billet → forging → hot flash → hot flattening and shaping → burring → shot blasting → Machining → Heat treatment → shot blasting → hot galvanizing → cold shaping → assembly. Among them, hot flash and hot flattening and shaping processes are realized on the punching machine; Machining procedures include: drilling → chamfering → tapping and other steps.
Due to the previous two traditional shackle body production process is lengthy, labor, equipment occupation, energy waste, high production costs, so the following production process has been introduced.
Instead of milling, instead of hot flattening, try to apply hot over cutting technology. Therefore, the process flow is optimized as follows: blanking → billet making → forging → hot over cut flash → deburring → shot blasting → Machining → Heat treatment → shot blasting → hot galvanizing → cold shaping → assembly; Among them, the machining process includes: drilling → chamfering → tapping and other steps
