Shearing machine |
摘要 |
A shearing machine for cutting off a material being continuously fed at a constant high speed into a relatively short lengths requiring adjustment of the revolution speed of a driving motor only within a relatively small range. The shearing machine comprises mainly three sections: a reciprocating mechanism driven by a motor to move cutters horizontally, a travelling assembly and double-acting cylinder to drive a movable cutter vertically while being moved horizontally, and a two-way rotary valve driven by the motor to control the double-acting cylinder device in conjuinction with movement of the reciprocating mechanism. The reciprocating mechanism translates rotary torque into reciprocating linear motion of relatively small stroke length. The two-way rotary valve is driven directly by the motor, facilitating synchronization of horizontal cutter speed with material feed speed and rapid movement of the cutters without any response delay.
