1、直冷式保護盒特點：冷水通過模具內腔進行循環冷卻，這種冷卻效果非常直接，解決了長期焊模冷卻不到位的問題
　　Features of the direct cooling protection box: the cold water circulates through the inner cavity of the roller sets for cooling. The cooling effect is very direct, which solves the problem of insufficient cooling of the welding for a long time.
　　2、采用焊盒外部調模設計，從根本上解決了焊盒內調模的難題
　　By adopting the design of external roller sets adjustment of welding box, the problem of internal roller sets adjustment of welding box is solved fundamentally.
