材料：模具彈簧選用高應(yīng)力，高速振幅，耐熱性優(yōu)良，疲勞壽命長的合金鋼材料。
Material: the mould springs are made by the alloy steel of higher strain、higher amplitude、heat resting、long-time used.
特點：
Point:
一、 材料形狀：呈矩形截面圓角圓邊形狀，與一般矩形直角直邊的有顯著區(qū)別，彈簧在高頻率工作時可以減少應(yīng)力集中，提高使用壽命。
One: Shape of material: Appear as the rectangular section round edge shape which different to the rectangular cartesian straight edge. The stress concentration will be reduced when the springs are working frequently, and also raise the time of using.
二、 強化處理：彈簧經(jīng)過表面強化處理，其表面組織結(jié)實，提高了應(yīng)力集中點的強度，使彈簧疲勞壽命延長，對高應(yīng)力，高頻率有特殊效果。
Two、Surface peening :After the treatment on each spring, both of the surface tissue and the stress concentration point will be more stronger, and also extending the using time, especial for the higher stress and higher frequency condition
三、 強壓處理：每只彈簧做三次或三次以上強壓處理，消除了使用前的內(nèi)應(yīng)力，保證彈簧使用時不會發(fā)生變形，縮短，斷裂等現(xiàn)象。
Three、Prestressing : Each spring will be prestressed by three or more times, in order to reduce the internal stress before using, keep sure that there will not be any crushed, shorten or broken appeared.
四、 使用壽命：根據(jù)彈簧的行程長度，頻率來決定。
Four、Using times: Decided by the actual working condition, such as working length and the frequency.
