Abstract
The invention discloses a continuous cold extruding device for asymmetric splines. The continuous cold extruding device comprises a hydraulic machine, an ejector rod and a mold. The mold is installed on a lower working platform of the hydraulic machine. The ejector rod is installed on an upper working platform of the hydraulic machine. The mold comprises a guide mold body and an extruding mold body. The guide mold body is installed on the extruding mold body. A guide mold cavity matched with parts is formed in the guide mold body. An extruding mold cavity matched with the to-be-machined splines in shape is formed in the extruding mold body. The axis of the guide mold cavity and the axis of the extruding mold cavity are located on the same straight line. By means of the manner, continuous cold extruding machining can be carried out on the multiple parts through the continuous cold extruding device, and the production efficiency is greatly improved.
