钣金工

As the application of the methods given, involute helicoid, which is widely applied in engineering, is developed into plane. And the problem in plate metalwork, which is t he development of square-circle tie-in, is also solved by the method.

其一是钣金工中方-圆类接头的展开问题，该问题的解决是锥面展开方法的成功应用；其二是螺旋输送器的核心部件——铰龙的展开问题，它是切线曲面展开方法应用的典型实例。

This method is most special is the principle of simple and clear, setting out the process visible and tangible, it is applicable to a little bit knowledge of sheet l scene lofting geometry, which is a revolutionary approach, which not only greatly reduced the mapping workload, but also a great convenience in construction. Same time, it can also be a more traditional method (open show diagram drawing or galvanized sheet cut oil felt like, after re-opening in the pipe body gestures draw the cutting line method) is more accurate and pipe sections match exactly between the butt, thereby ensuring the steel fork tube and bend production quality.

该方法的最大特就点是原理简单明了，放样过程看得见摸得着，很适用于稍有一点几何常识的钣金工现场放样，这是一革命性的方法，它不仅大大地减少了制图工作量，而且也极大方便快捷了施工，同时它还可较传统方法（绘制开口展图后用油毛毡或镀锌板裁样再后在管身上比划绘出开口切割线的方法）来得准确无误与管段间对接严丝合缝，进而保证钢岔管和弯头的制作质量。

The company also has a cohesive and professional teem;qualified engineers designers,top gun technicians well-trained sizing sheet engineers and solderers,professional staff of the service after sales of building in project;experienced marketing managers.ect.

公司还拥有一支凝聚力很强的专业团队、资深的工程师和设计师、专业过硬的技术员、训练有素的钣金工、焊工、专业的安装售后服务员、经验丰富的营销经理人等。
