Specific embodiment
A kind of hydraulic shear containing blade clearance adjusting means, as shown in figure 1, include hydraulic shear cutting frame 1, by twice parallel
Shearing knife rest 7 and the shearing cutting edge 6 being arranged on shearing knife rest 7 that horizontal slide rail is fixed on hydraulic shear cutting frame 1, in hydraulic shear
Fixing tapered wedges 2, mobile tapered wedges 3, driving means 4 and shearing knife rest lateral thruster are additionally provided with cutting frame 1；
Driving means 4 are coupled with mobile tapered wedges 3 to drive this movement tapered wedges 3 vertically action；Described movement
Tapered wedges 3 and shearing knife rest 7 are placed between fixing tapered wedges 2 and shearing knife rest lateral thruster so that fixing tapered wedges 2, moving
Tapered wedges 3, shearing knife rest 7 are parallel successively with shearing knife rest lateral thruster to be close to arrange；The inclined-plane of mobile tapered wedges 3 is oblique with fixing
The inclined-plane of voussoir 2 relatively and is set parallel to each other.
Described shearing knife rest lateral thruster is by fixed block 8, guide finger 9, holddown spring 10, housing pin 11 and compact heap
12 compositions；
Described compact heap 12 is placed between described fixed block 8 and shearing knife rest 7；
Tapped through hole perpendicular to described compact heap 12 is offered on described fixed block 8, holddown spring 10 is placed in this screw thread
