Extrusion rod and application of extrusion rod to sunflower heat dissipater profile

Abstract

The invention discloses an extrusion rod and application of the extrusion rod to a sunflower heat dissipater profile, and relates to a method for producing sunflower heat dissipater profiles. A pressing head is in threaded connection with the open end of a barrel-shaped main body of the extrusion rod; a spring is arranged in the barrel-shaped main body; a through hole coaxial with the spring is formed in the pressing head; an inner supporting rod is inserted into the through hole in a clearance manner; the front end of the inner supporting rod is fixedly connected with a rod head; and the rod head is arranged in the barrel-shaped main body in a clearance manner. Before the extrusion starts, the inner supporting rod extends into a tubular blank, and the rod head realizes a supporting function, so that a metal material can be prevented from flowing to the axis during the extrusion. According to the extrusion rod, tubular metal is taken as an extrusion molding blank, so that a metal material can be more reasonably distributed, the flowing speed at a profile outlet is more uniform, metal dead regions are greatly reduced in the extrusion process, the extrusion force is reduced, the burden on power equipment is alleviated, the energy consumption is also reduced, and the service life of a die is prolonged.

Description

technical field [0001] The invention belongs to the field of profile processing, in particular to a method for producing sunflower radiator profiles by using tubular blanks. Background technique [0002] The application of radiators is becoming more and more widespread today, and it is involved in many fields. [0003] Many radiator profiles are produced by hot extrusion, and most of them use solid billets in the production process. However, in the actual production process, it is still difficult to produce some Sunflower radiators with larger outer diameters and higher heat dissipation teeth. The main reasons are: there is a serious dead zone phenomenon at the front end of the mold during extrusion, and the flow of metal materials is difficult. , Unbalanced feeding, large extrusion force, short mold life, etc. At present, there is no report on the use of tubular blanks to produce sunflower radiator profiles. Contents of the invention [0004] The first object of the pr...
