Step 10 eight: ball blast carries out roll cast using Caterpillar type shot blasting machine, and the control ball blast time is 7 minutes.
Through the above technical solutions, needing for be put into forge die raw material, passing through later when carrying out forging and stamping production
Press machine squeezes forge die, so that the raw material of mould inside deforms and is full of the die cavity of forge die.Carry out blocking it
Before, jumping-up first is carried out to raw material, bending is carried out to raw material again later, so that the mold cavity shapes of the shape of raw material and Preform Die are more
Be it is close, in this way when carrying out blocking processing, the raw material inside Preform Die only needs to deform lesser amplitude to surrounding
The die cavity of Preform Die can be full of, improve the processing efficiency of blocking to a certain extent.The forming process of product is divided into
Two parts of blocking and finish-forging, can mold the more careful product of surface characteristics.Product is carried out after finish-forging terminates
Solution treatment and ageing treatment, enable product hardness with higher, and its hardness can reach 100 Brinell hardness, produce
Product can tensile strength with higher, and its tensile strength can reach 345 megapascal, product can surrender with higher it is strong
Degree, and its yield strength can reach 315 megapascal.Product needs to undergo two processes of alkali cleaning and pickling, so that the table of product
The oxide skin and erosion in face can obtain more adequately removing.
Preferably, the raw material selected in the step 1 is aluminium alloy, and the mass ratio of the al alloy component are as follows: Si:
