The hammer of 630 KJ is an advanced forge device, whose hit energy and hit power during forge process are the key elements to forge quality. Therefore, from analyzing mathematical model of hit power, the forge quality can be developed. In this paper, the device we designed can measure acceleration change during forge, from which the mathematical model between acceleration and hit power can be constructed according to the change discipline between them. The digital signal processing system of functional model based on FPGA is designed, in which Verilog HDL program language compiled by Quartus II environment is downloaded into FPGA to implement all the functions. Such method can improve the speed of digital signal processing, from which the max hit power and the max hit energy can be got according to acceleration and displacement.
