Constant strain rate flow curves have been analyzed in order to develop a constitutive model to describe the high temperature behavior of the materials using the standard kinetic rate equation that relates the steady state flow stress (σ) To the test temperature (T) and the strain rate (ε ) given by [4]: (1) Where σ is the flow stress, n is the stress exponent, Q is the activation energy, and A is a constant.
In the pre-process of DEFORM2D, the stress-strain curves in Fig. 1 were inputted as the material properties of GH4169.

It is composed of control computer, press driver, die driver, material rack driver, material transport equipment driver, lubrication driver and finished product collector, is shown in figure 2.
In this paper, we consider the material, the blanking force, the blanking frequency, the feed step, the product piece number, etc.
According to the relationship between the blanking force and the material hardness, blanking force and the material strength, we calculate the blanking force respectively.
Considering the wear of the die cutting edge, the nounniform of the die clearance, the fluctuation of the material performance and the deviation of the material thickness, the traditional blanking force expressiong is as follows for the flat cutting edge: (3) where P is the blanking force, k is the coefficient determined by the material and its thickness, l is the circumference of the product, t is the material thickness, and is the tensile strength of the material.

Microstructure studies were made on polished sample surfaces using optical microscopy after electrolyzing in 20% perchloric acid and 80% ethanol solution for 5 seconds. 3 Results and discussion 3.1 Anode material selection The electrochemical performance of the anodes in the constant current tests was shown in Tab.2.
Therefore, from the point of view of potential and dissolution, 6# anode is selected as a promising low driving voltage sacrificial anode material for steady working potential, uniform dissolution and high current capacity. 3.2 Effect of environment parameters on performance of the anode Data in Tab.3 show that the current capacity of 6# sample, Al-0.55%Zn-0.5%Bi alloy anode, was greater than 2500Ahr/kg under all the experimental condition.
