Its design essence is, formerly after total conceptual design, a design which points each main spare part, question of installing and making a reservation etc., and carry on the intensity to check and test to the specific part, and in relevant thematic parts, analysis of paring question that the lifespan of very beginning of the hammer lengthens in detail. In the design of each spare part, should include the choice, sureness, demand processed, structure craft satisfication of the size of the material, and the demand for cooperating with other parts, etc.. When the intensity is checked, should use relevant formulae, carry on the analysis of the dangerous position, need to check form, mapping, calculation, etc.. Then to install , work course , work situation after predict that carries on more overall inspection whole, give consideration to the question in such respects as maintaining and safety ,etc. at the same time. Finally, choose to analyse in machining accuracy, public errand to two groundwork parts, economy and dependability that the breaker soed as to ensure is designed finally.
