Background technology
The little type steel bar cut-off machine of a kind of hand-held occurred in the market, this kind of bar cropper have use flexibly, the advantage of fast shut-off, if any people on July 27th, 2007 apply for, the patent No. 200720112377.1, name be called the utility model patent of " a kind of bar cropper ".But the disadvantage that the bar cropper that the bar cropper of prior art comprises above-mentioned patented technology exists is: be 1. limited to appearance and size, pump assembly pump oil mass is operationally limited, so cut off responsiveness when carrying out bar cutting work comparatively slow, work effect of cutting machine is lower; 2. the oil suction chamber of hydraulic part is come by the elastic shrinkage of rubbery human body when oil transportation, rubbery human body is located in clamp block, and rubbery human body is by after oil temperature rising, caoutchouc elasticity can be deteriorated, so oil transportation slows, fuel delivery reduces, so direct oil-feed affecting oil suction chamber, causes bar cropper operationally effect reduction.
Summary of the invention
For overcoming the deficiency that background technology exists, the utility model is taked following technical scheme to implement:
High-performance rebar cutting machine, by the cut-off parts axially arranged, hydraulic part and power section composition, cut-off parts comprises clamp block, dead knife and movable blade, dead knife is fixedly located in clamp block, movable blade is actively installed in clamp block, after movable blade and dead knife relative motion, reinforcing bar is cut off, it is characterized in that: hydraulic part comprises the pump housing, assembly of the plunger pump and pump shaft, the plunger hole being provided with four radial direction in the pump housing installs four assembly of the plunger pump, the pump oil action of assembly of the plunger pump is promoted by the roller be installed on the eccentric spindle nose in pump shaft front end, pump shaft carries out pivoting support by the pump housing, the rotation of pump shaft is driven by the motor of power section.
Described assembly of the plunger pump is made up of the leather cup set gradually up and down in plunger hole, upper spring seat, little spring, lower spring cup, plunger spring and plunger, the oil-in of transversely cutting groove as assembly of the plunger pump is offered in the middle of plunger hole, transversely cutting groove communicates with the oil suction chamber of the described pump housing, under the spring-force driven dual of plunger spring, the bottom of described plunger is tight against the rolling surface of described roller all the time.
Pump housing front end sets out oil pocket, go out in oil pocket and be movably equipped with first piston, first piston is connected with movable blade by knife bar, the front end of first piston is provided with the first spring, oil suction chamber is established in pump housing rear end, be movably equipped with the second piston in oil suction chamber, the rear end of the second piston is provided with the second spring, go out oil pocket be positioned at first piston before cavity A and oil suction chamber be positioned at the second piston before cavity B connected by the built-in oil circuit of the pump housing.
After adopting technique scheme, the attainable Advantageous Effects of bar cropper of the present utility model is: 1. appropriate design pump body structure also adopts four assembly of the plunger pump simultaneously, so, bar cropper operationally just can largely improve pump oil mass, so cut off responsiveness block, effectively improve and cut off effect; 2. the oil transportation of oil suction chamber has been come by the second piston and the second spring, rubbery human body structure compared to existing technology, obviously there is the advantage that oil transportation is stable, though during work oil temperature raise after oil transportation speed also can constant speed constant, thus effectively improve work effect of bar cropper.According to system test, the utility model can improve effect more than 30%.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
As shown in the figure, high-performance rebar cutting machine of the present utility model, by the cut-off parts axially arranged, hydraulic part and power section composition, cut-off parts comprises clamp block 15, dead knife 16 and movable blade 17, dead knife 16 is fixedly located in clamp block 15, movable blade 17 is actively installed in clamp block 15, after movable blade 17 and dead knife 16 relative motion, reinforcing bar is cut off, hydraulic part comprises the pump housing 5, assembly of the plunger pump 12 and pump shaft 8, the plunger hole 6 being provided with four radial direction in the pump housing 5 installs four assembly of the plunger pump 12, the pump oil action of assembly of the plunger pump 12 is promoted by the roller 13 be installed on the eccentric spindle nose 14 in pump shaft 8 front end, pump shaft 8 carries out pivoting support by the pump housing 5, the rotation of pump shaft 8 is driven by the motor 7 of power section.
Described assembly of the plunger pump 12 is made up of the leather cup 121 set gradually up and down in plunger hole 6, upper spring seat 122, little spring 123, lower spring cup 124, plunger spring 125 and plunger 126, the oil-in of transversely cutting groove 18 as assembly of the plunger pump 12 is offered in the middle of plunger hole 6, transversely cutting groove 18 communicates with the oil suction chamber 10 of the described pump housing 5, under the spring-force driven dual of plunger spring 125, the bottom of described plunger 126 is tight against the rolling surface of described roller 13 all the time.
