Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
As shown in the figure, the invention provides a kind of reinforcing steel shearing mechanism with multiaspect use moving cutting tool, described reinforcing steel shearing mechanism comprises: a revolvable eccentric shaft 8, and one end articulated linkage 2 one end of eccentric shaft 8, the other end of connecting rod 2 is by connecting one end of the hinged shear arm 3 of bearing pin 13; Shear arm 3 hinged supports are on shear arm back shaft 10, and shear arm 3 other ends are equipped with moving cutting tool 6; Shear arm back shaft 10 is fixed on the fixing tool rest 4 being integrated with frame 1, on fixing tool rest 4, dead knife 5 is housed.
Described moving cutting tool 6 is one and has symmetric polygon cylinder, and each limit of polygon cylinder is the moving cutting tool shear blade 12 of moving cutting tool 6; Moving cutting tool 6 is fixed on shear arm 3 other ends by securing member, and the moving cutting tool shear blade 12 on moving cutting tool 6 moves the reinforcing bar 7 of shearing through dead knife 5 along the end face of dead knife 5.
