[Chinese instrument network instrument research and development] In the explanation process of the chemistry class experiment, the glass instrument is fragile, the connection is inconvenient, and the paper instrument model paste is fixed and troublesome. These problems inevitably confuse many teachers. How to overcome the limitations of glass instruments and paper instruments, so that the experimental explanation becomes convenient, efficient and safe?
Recently, the “Magnetic Chemistry Experiment Instrument Components†developed jointly by the teachers of Chongqing Yizhong Chen Guojun and Zhang Guohui solved this problem. This innovation has won a utility model patent certificate issued by the State Intellectual Property Office of the People's Republic of China.
Two teachers, Chen Guojun and Zhang Guohui, found that due to the limitations of the instrument, the experimental demonstration session in the chemistry class was inefficient. To overcome this problem, they overcome the safety problems of glass instruments by making models and overcome the splicing problems of paper instruments through magnetic patches. After repeated modifications and adjustments, we finally developed a convenient, efficient, and safe magnetic chemistry experimental instrument assembly.
According to reports, the component contains a magnetic patch made from an experimental instrument model. When the experimental instrument model is used on a blackboard or a whiteboard, various experimental devices can be spliced ​​to facilitate the correction and analysis of the teacher at any time during the explanation. Both sides of the display whiteboard are magnetic. One side can be used by students to design the experimental device with a magnetic instrument model. The other side is also magnetic. It is convenient for the students to explore the activity, and then the group work is presented on the blackboard as a whole and displayed.
The acquisition of this patent certificate is a great affirmation of the two teachers’ awareness of scientific and technological innovation. They actively think in their work, give play to the spirit of scientific research, and solve problems according to the actual situation. At the same time, they also allow students to see the teaching wisdom of teachers.

Angle Punching Machine is special used for angle tower industry, for transmission tower, electric tower, power tower, electric power fittings, structure storage facility, and steel structure industry.
For small steel angle, we have TAPM1010, TAPM1412, which have high speed punching efficiency for high speed feeding cnc carriage.
For heavy angle, TAPM1516, TAPM2020 for angle punching, marking, shearing is more accuracy.
Big project angle tower have to use cnc angle drilling and marking line, which angle size exceed 20mm, 25mm
Plate Drilling Machine is for 1500*800mm, 1500*1000mm working area, thickness within 25mm, TPPD cnc plate drilling and Punching Machine is more competitive.
2000*1200mm, 2000*1600mm, 3000*1600mm, 3000*2000mm steel plate working are could use High Speed CNC Drilling Machine, tighten by T-Slot clamps 12 pcs, 7.5kn each. More power for plate holding.
Beam Drilling Machine have single drilling spindle line and 3 drilling spindles and 9 drilling spindles water cooling, adopted BT40/BT50
H I U Channel steel beam with high efficiency for steel structure.
