動の走間往復動剪断装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a running shearing device, and more particularly to a running reciprocating shearing device driven by a crank or eccentric drive for shearing thick and wide metal materials.

る。 In order to efficiently cut large cross-section steel materials such as those produced in steel plate rolling equipment, a large-capacity ultra-thick running shearing device is required. The structure of a shearing machine for shearing large cross-section steel materials increases in proportion to the power of the thickness of the steel material, so when performing high-speed running shearing, the inertia of the shearing machine becomes extremely large.

た。 In conventional running shearing devices, the mechanism that moves the shearing blades to match the feed rate of the shearing material and the mechanism that drives the shearing blades and shears the material are constructed inseparably, and therefore both mechanisms are integrated. Since it is driven by two power sources, the power source must have a large capacity due to its large inertia, and in the case of extremely thick plates, there are problems such as the inability to stop and shear.
