Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminum material extrusion die technical field relates to a kind of extrusion dies with anti-collision structure. BACKGROUND

[0002] There are several shortcomings in the existing aluminum extrusion die in avoiding aluminum rod and forming cavity external impact, mainly reflected in die design, material selection and extrusion process control. First, it is difficult to accurately predict the flow behavior of aluminum material in the extrusion process during die design, which may cause aluminum rod to impact the outside of forming cavity due to unstable movement or too fast speed when entering forming cavity.
