Description
Technical field
The utility model relates to the cold headers fields that steel ball processing uses, and are specifically related to a kind of cold headers blank guide rail
Assembly.
Background technique
Steel ball belongs to an important component of bearing, and the preceding working procedure that steel ball cold heading process is produced as steel ball is directly determined
The cost and quality of steel ball production are determined.The main transmission of ball cold header is transmitted by main motor drive big belt pulley, again by power
To crankshaft, the power of crankshaft it is orderly pass to three mechanisms: drive master slider to move back and forth by crank combination, connecting rod and realize
Punching press movement；Blank cam is driven to realize blank movement by blank time adjustment plate, pull rod；By feed adjustment plate drive into
Expect that mechanism realizes intermittent feeding.The close fit of three parts forms a complete steel ball cold heading machine, by the steel of certain specification
Silk is by feeding, cutting, cold-heading until steel ball blanks.
What is be wherein closely related with blank process is blank guide rail assembly.The component mainly includes that tool apron, cutter shaft are led
