During rail laying, the loop part of the U-shaped bent loop is knocked bent to hold down the foot of the rail and in this way, the sleeper and the rail are connected together.
铺轨时，“U”形弯环的环部被砸弯，压住钢轨的底脚，即可将轨枕与钢轨联结在一起。
The structure can make the back U-type bent part stripped effectively, and also increase the reliability, safety and service life of the die.
该模具结构不但解决了倒u形弯曲件出模困难问题，而且模具的可靠性、安全性及使用寿命显著提高。
When the U-shaped bent loop is broken, the nuts under the sleeper can be screwed off and a new U-shaped bent loop can be assembled for restoring use.
当“U”形弯环断裂时，可将轨枕下面螺帽旋下，换上新的“U”形弯 环，即可恢复使用。
