Description
Technical field
The utility model relates to plant equipment field, relates in particular to a kind of mechanical transmission-type steel bar cutter.
Background technology
Steel bar cutter is reinforcing bar to be cut into the special-purpose machinery of Len req, and the application on heavy construction building site is very extensive.Steel bar cutter is divided into two kinds of machine driving and hydraulic drives.Mechanical transmission-type bar cropper in the past, during work, mostly adopt motor after one-level V--belt Drive and secondary gear transmission deceleration, drive crankshaft rotating, bent axle promotes connecting rod does reciprocating linear motion slide block and cutting blade in the slideway of support, makes movable blades and fixed blade be staggered and cut off reinforcing bar.This class steel bar cutter is owing to having adopted the transmission of one-level band and secondary gear transmission, when motion and power pass to slider-crank mechanism, the process that has an Efficiency Decreasing, in addition, structure is not compact, and weight is large, installs, debugs complicated, and owing to requiring gear drive to have certain precision, manufacturing cost is also higher.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, cuts the mechanical transmission-type steel bar cutter that efficiency is high.
The technical solution adopted in the utility model is: a kind of mechanical transmission-type steel bar cutter, comprise casing, motor, shaft coupling, eccentric shaft, mounting plate, bottom plate, cut case, described eccentric shaft is connected with described motor by shaft coupling, the described case that cuts, between described mounting plate and bottom plate, cuts case described in described eccentric shaft passes.
Further, the described case that cuts is mainly comprised of casing, connecting rod, slide block, block, voussoir, cutting blade and ledger-plate, described connecting rod is connected with described eccentric shaft, described cutting blade is connected with described box inside wall, described ledger-plate is connected with described slide block, described eccentric shaft passes described slide block, and is attached thereto by described connecting rod, and described voussoir is between described two blocks.
Further, described voussoir is connected with sprocket wheel by steel wire rope, and described sprocket wheel is also connected with a handwheel.
Further, between described cabinet wall and described slide block, be also provided with a spring.
Further, described in, cutting case is provided with for placing the groove of reinforcing bar.
Further, the groove depth of described groove is greater than the diameter of reinforcing bar.
Further, described cutting blade and ledger-plate blade are positioned on straight line.
Further, in described slide block, be provided with the groove being connected with described connecting rod.
The beneficial effects of the utility model are: 1. the length of connecting rod reduces, more compact structure, and transmission force property improves, and extend service life; 2. eccentric distance e is very little, and the cutting force of generation increases; 3. transmission is simple, has reduced the number of revolute pair, has improved efficiency; 4. the cutting time shortens, and has greatly improved labor productivity; 5. compact overall structure, floor space is little.

The specific embodiment
In order to make the advantage of the purpose of this utility model and technical scheme clearer, below in conjunction with accompanying drawing and example, the utility model is further elaborated.
As shown in drawings: a kind of mechanical transmission-type steel bar cutter, comprise casing 1, motor 2, shaft coupling 3, eccentric shaft 4, mounting plate 5, bottom plate 6, cut case 7, described eccentric shaft 4 is connected with described motor 2 by shaft coupling 3, the described case 7 that cuts, between described mounting plate 5 and bottom plate 6, cuts case 7 described in described eccentric shaft 4 passes.The described case 7 that cuts is mainly comprised of casing 8, connecting rod 9, slide block 10, block 11, voussoir 12, cutting blade 13 and ledger-plate 14, described connecting rod 10 is connected with described eccentric shaft 4, described cutting blade 13 is connected with described casing 8 madial walls, described ledger-plate 14 is connected with described slide block 10, described eccentric shaft 4 is through described slide block 10, and be attached thereto by described connecting rod 9, described voussoir 12 is between described two blocks 11.In described slide block 10, be provided with the groove being connected with described connecting rod (9).Described cutting blade 13 and ledger-plate 14 blades are positioned on straight line.Described voussoir 11 is connected with sprocket wheel 16 by steel wire rope 15, and described sprocket wheel 16 is also connected with a handwheel 18.Between described casing 8 inwalls and described slide block 10, be also provided with a spring 18.The described case 7 that cuts is provided with for placing the groove 19 of reinforcing bar.The groove depth of described groove 20 is greater than the diameter of reinforcing bar.
During work, reinforcing bar is placed in and is cut in case 7 upper grooves 19.Power-on, is directly with movable eccentric wheel 4 rotations by motor 1, and eccentric shaft 4 forms eccentric mechanism together with connecting rod 9 and slide block 10, its eccentric throw is e, and in the scope allowing in machining accuracy, making crank length is that eccentric throw is enough little, like this, can, in the situation that motor torque is certain, increase cutting force.When eccentric shaft 4 turns over 180 ° by shown position, the distance that slide block 10 is moved to the left is 2e, under the effect of voussoir 12 gravity, falls rapidly, and 2e gap is eliminated; When camshaft forwards 360 ° to by 180 °, slide block 10 promotes the box-frame 2e that moves right together with voussoir 12, is fixed on the moving knife on casing 8,13 2e that move right, and now, voussoir 12 falls, and 2e gap is eliminated, and completes the circulation of one-period.Along with the continuous rotation of eccentric shaft 4, often turn around, cutting blade 13 2e that moves right, until under the effect of cutting force, by bar cutting.After cut-out, rotate handwheel 17 voussoir 12 is promoted, cutting blade 13 sets back under the active force of spring 18.
