结构和特点：
　　“鑫源”牌煤矿折弯机主要用于煤矿巷道U型钢或工字钢的折弯与效直。为适应不同截面巷道的需要，只需更换模具，即可压制不同截面的U型钢成品和不同规格的型材，推广使用U型钢拱梁结构承受载荷是传统工字钢平梁的数倍，即经济坚固又*可靠。

此设备主机为四柱液压机，结构紧凑，液压传动平稳，电气柜及泵站，板面清晰，操作方便，压力大小随时调整，*过载装置配备合理，操作*，可靠耐用。
　　为修旧利废只需要更换模具还可以校直报废的旧拱梁二次压制成型使用，减少了材料投入，节约了成本，产生了客观的经济效益，何乐而不为呢？

This device is the host for the four-column hydraulic machine, compact structure, smooth hydraulic transmission, electrical cabinets and special pumping station, board a clear, easy to operate, the pressure at any time to adjust the size, safety overload device is equipped with reasonable, safe, reliable and durable.

In order to meet the needs of different sections of roadway, just replace the mold, you can suppress the different sections of the U shaped steel finished products and different specifications of the profile, promoting the use of U shaped steel arch-beam structure to withstａnd load is a traditional I-beam flat beam several times, that is, economic strong, safe and reliable.

To repair old or discarded only need to replace the mold can also scrapped the old school straight arch beam forming to suppress the use of the second, reducing the material input cost savings, resulting in an objective economic benefits, why not?
