Crank rotary flying shears machine

Page view
[Abstract]:
用飞剪机剪切厚度较大的板带或钢坯时,为了保证剪后轧件剪切断面的平整,往往采用刀片作平移运动的飞剪机。曲柄回转杠杆式(也称曲柄连杆式)飞剪机就是此类飞剪机的一种。     图9-3是曲柄连杆式飞剪机结构图。刀架1作成杠杆形状,其一端固定在曲柄轴2端部,另一端与摆杆3相连。当曲柄轴2转动时,刀架1作平移运动,固定在刀架上的刀片能垂直或近似地垂直轧件。  由于这类飞剪机在剪切轧件时刀片垂直于轧件,剪切断

When the fly shear machine is used to shear the thick plate or billet, in order to ensure the smooth shear section of the rolled piece after shear, the fly shear machine with the blade as the translation movement is often used. The crank rotary lever type (also known as the crank connecting rod type) flying shear machine is one of these flying shear machine.

 It should be pointed out that in the modern continuous small steel mill, the range of product range is 10-50mm, and the range of rolling mill speed variation is 2-20m/s. Therefore, the single use of the above rotary or crank-link flying shears can not meet the production requirements, and set up two flying shears at the same time of greater investment. For this reason, a crank - rotary flying shear machine (as shown in figure 9-4) has been developed. When the shear section is large and the speed is low, the flying shear is a crank connecting rod (figure 9-4a). When the shear section is small and the speed is high, the connecting rod 5 is removed from the tool holder 1 and fixed together with swing rod 4 on the box body 3 of the flying shear (figure 9-4b). At this point, it is a rotary flying shear. This kind of flying shearing machine can change quickly and conveniently, can adapt to the situation that the speed range of rolling piece and shear range have very big change.
