Description
Technical field
The invention belongs to technical field of forging, it is related to a kind of half-shaft blank hydraulic press forging system and processing method.
Background technology
Currently, auto parts and components semiaxis forging processing technology usually have it is following two：
The first adds the mode of production of pneumatic hammer Closed-Pattern Match Forging Technique, pattern to be using pneumatic hammer dead man：Pneumatic hammer adds air
Hammer pattern, process route：Blanking incudes whole heating, and pneumatic hammer dead man, open die forging is thick, pre-formed, pneumatic hammer ring flange at
Shape.
The advantages of technology is to pull out cone bar using existing facilities air hammer, and the input of equipment is small；The disadvantage is that due to adopting
Cone bar is pulled out with pneumatic hammer, is influenced to will produce eccentric, twisted situation by operating personnel's operation level, technique falls behind, forging
Precision is low, and workpiece surface quality is poor, and following process surplus is big, high rejection rate, and labor intensity is big, loose tool is perishable, easy to wear,
Of high cost, productivity is low, and work is also unstable, and working environment is poor, can only adapt to small batch production.
Second of mode of production using the pre- upsetting oiling press flange forming of hydraulic press：Hydraulic press oiling press mould, technique
Route：Blanking incudes local heating, the poly- material of hydraulic press, local repair temperature, the forming of hydraulic press ring flange.
The advantages of technology is to utilize bar excircle orientation, is not influenced by operating personnel's factor, accurate positioning, product matter
Amount is stablized, and material consumption is few；1, production efficiency is high；2, labor intensity is low；3, production cost is low；4, accurate size is high, more than processing
Measure small, material-saving；5, energy saving；6, stable working, has started the epoch of steam power metal forming machinery, and vibrations are small；7, noise is small.
The disadvantage is that the disposably input of equipment is larger, which adapts to produce in enormous quantities.
Invention content
It is different by replacing the object of the present invention is to provide a kind of half-shaft blank hydraulic press forging system and processing method
