When, it is ensured that it is heated that range is not too big, and causes at the position that camshaft serpentine head is connected with axle portion because being heat-treated not
The loss of strength caused by；
Process B: by the vertical type chamber for being put into extrusion die of the raw material A after being heated, set raw material A city vertical state
It sets, and is heated portion of the end of a upward, and the pressure head of face extrusion die；
Process C: starting extrusion die is moved down using pressure head and is heated portion of a progress precompressed to raw material, makes raw material
The oxide layer for being heated one end falls off, during preventing subsequent forming, the oxide layer on surface shape on the serpentine head of camshaft
At pit；
Step D: jumping-up is carried out to one end that raw material is heated using pressure head, so that being heated portion of the whole height of a
It reduces；
Process E: pressing to a that is heated portion of after jumping-up using the pressure head of extrusion die, the portion for being heated raw material
Point a intracavitary is shaped to workpiece embryo material in the type of extrusion die；
Process F: extrusion die is opened, and workpiece embryo material is demoulded from extrusion die, camshaft is made, while to extrusion die
Tool is cooled down.
In one of preferred embodiment, in process F, cooling can also be that carry out of mold is formed graphite water
It after mist, being sprayed onto extrusion die, extrusion die is cooled down, graphite water can not only cool down the type chamber of mold, meanwhile, also
The inside of mold can be lubricated.
In another preferred embodiment, in process C, one be heated to raw material is moved down to pressure head when utilizing
After end carries out precompressed, pressure-air is blown to raw material surface, the oxide layer for making raw material be heated one end falls off, and prevents oxide layer from falling off
The type that residue afterwards stays in mold is intracavitary.
It should be noted that the heating temperature for being heated portion of a of raw material can be to be taken the photograph in 1000-1200 in process A
Within the scope of family name's degree, select according to the actual situation.
The above method selects the column raw material of an entirety, extrusion forming after heating to part of it, it is ensured that cam
The serpentine head of axis and axle portion are integrated, it is ensured that the intensity of camshaft prevents from being broken, meanwhile, an extrusion forming, letter
