The finite element analysis of the crank flying shears;

Research and improvement on the auto control system of flying shear on the high speed wire rolling line;

Redesign and Improvement of Starting-Stop Flying Shears;

Improvement of cut mode of No.2 flying shears

2 flying shears of Wire Plant of Han Steel,steel accumulation breakdown got fewer,operation ratio raised and products more qualified.

Adjustment of speed and position parameters on motion control system of start-stop shear;

Reform of Continuous Shear in Finish Rolling;

3 shear wasn't satisfied with the new production requirement.

Optimization of double eccentric pendulum fly shear;

To reform old fly shear used of axial tire type clutch and brake,the questions of incorrect electromagnetic clutching and incorrect brake control on old fly shear are saved.

The horizontal disk shears can not shear rhombohedral section of rolled material before it is came into finish rolling mill,and so the vertical shaft type disk fly shears is designed and it's practical calculating formula is got based on the priciple of operation of disk type shear machine and fly shears.

The critical equipment and its control,to realize semi-endless rolling of strip were introduced,which were including high-speed flying shear.

Flying shears equipment is one of the important continuously imported metallurgical equipment in china.

A succinct and practical method for calculating mechanical parameters of flying shears is obtained.

This paper studies the effect of variant transmission plans of drum flying shears on the conditions of the forces on low driving gears of the hollow shaft sleeves and analyzes the forces on the shear mechanism and low eccentric driving shafts.
