The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model front view; Fig. 2 is the D-D cutaway view of left view among Fig. 1.
As shown in Figure 1 and Figure 2, the utility model provides a kind of hydraulic reinforcing-steel cutter, and its structure comprises: frame 1; On frame 1, be fixed with respectively as lower member: be equipped with bottom knife 7 following tool rest 6, the upper cutter head 4 of cutter 5, the workbench 8 of spacer bar 15 are housed.
The utility model also is fixed with master cylinder 2, compressed oil cylinder 3 and is connected the hydraulic system of master cylinder 2, compressed oil cylinder 3 on frame 1.
The piston 16 of described master cylinder 2 connects upper cutter head 4.Can realize moving up and down under hydraulic system drives when the piston 16 of master cylinder 2, the upper cutter head 4 that is connected with piston 16 drives cutter 5 and realizes that upward down cut moves.
The pressure head 9 of described compressed oil cylinder 3 pistons ends is positioned at workbench 8 tops.For cooperating shearing to reinforcing bar 15, need pressure head 9 that reinforcing bar 15 is fastened, pressure head 9 can firm fasten reinforcing bar 15 under the driving of compressed oil cylinder 3.
As shown in Figure 3, described hydraulic system comprises: pressure oil is supplied with part 20 and connected pressure oil control section 30.
It is general pressure oil feedwaies that described pressure oil is supplied with part 20.Pressure oil supply part 20 comprises by universal components such as oil pump 10, overflow valve 11, oil filters 14 forms pressure oil feedway commonly used, does not describe in detail at this.
