Description
The utility model relates to the electric tool that a kind of cutting edge that adopts the work of vibrocutting mechanism is done compound linear reciprocating motion, particularly for high rigidity materials such as carbon steel, cast iron, concrete, can be efficient, convenient, accurately, safely at the vibration electric hand saw of working site sawing.
The operation principle that existing cutting edge is done straight-line electric hand saw generally is by slider-crank mechanism of Motor Drive, doing simple linear reciprocating motion by slider-crank mechanism drive saw blade cuts, the cutting scheme of cutting edge is common cutting scheme, be cutting edge must continue the extruding cut material, so that be cut material formation elastic-plastic deformation zone in a big way, place, produce a large amount of sliding deformations and produce smear metal from the stress raiser fracture afterwards.With reference to the graph of a relation of cutting force P (t) under the common cutting scheme of accompanying drawing 1 and time t, in working angles, cutting force P (t) is the lasting cutting force of complicated wave form alternating force Psin ω t of having superposeed on a constant cutting force Pmean.Be P (t)=Pmean+Psin ω t, rather than a constant power.Constant force Pmean is the necessary condition that produces alternating force Psin ω t in the working angles, the heating in the working angles and the wearing and tearing of cutting edge mostly thus power cause.The main effect of alternating force is to cut, and produces smear metal.Because cutting force is big, in order to guarantee saw blade that cantilever installs unstability not when the cutting, must the used thickness size big saw blade is to obtain high rigidity, and thick saw blade cutting output is big, produces big cutting force, must need powerful motor, large scale high-strength structure spare again, make that machine volume, power consumption are big, Heavy Weight, and active force, the reaction force cut between the material are big, are difficult to grip when materials such as cutting iron and steel, are unsuitable for long-time hand-held and use.The disc type electric hand saw is simple in structure, and sawing speed is fast, also is with the cutting of common cutting scheme, but has volume, weight, defective that power consumption is big equally, particularly because design feature, can not the curve sawing, and be difficult to irregular workpiece be carried out sawing in the working site.Therefore, adopt the old-fashioned electric hand saw of common cutting scheme work since the cutting force when high rigidity material such as cutting iron and steel etc. big, be difficult to gripping, the easy unstability of saw blade, wearing and tearing, inefficiency, only be applicable to sawing timber or the close material of hardness with it.
The purpose of this utility model is exactly a kind of hard materials such as sawing carbon steel, cast iron that are mainly used in that design at the deficiency that exists in the above-mentioned existing electric hand saw, average cutting force is little during cutting, the sawing size is accurate, heat in metal cutting is atomic, do not have the cutting spark, the cutting-rate height, in light weight, volume is little, easy operating, vibration electric hand saw safe in utilization.Be used at the working site curve or straight line is sawed-off and the metal of high rigidity material such as sizing sawing carbon steel, cast iron and various, soft and alloy material and stone material, timber, plastic or other material.
The purpose of this utility model is achieved in that the utility model comprises handle, motor, decelerator, the motion case, once (amplitude with respect to the motion case done of saw blade is big in motion, the motion that frequency is low) mechanism, front supported beam, saw blade, it is characterized in that: secondary motion (saw blade do with respect to the fast vibration of motion slide block once) mechanism is installed on the once motion slide block of a motion, the decelerator that connects with motor have power transmission shaft A and two output shafts of power transmission shaft B respectively be installed in the motion case in motion and secondary motion mechanism connect, saw blade is fixed on the saw cramp slide block that connects with the drive link axial restraint of secondary motion mechanism, and scale mechanism is installed on the front supported beam.During work, the electric-motor drive decelerator, power transmission shaft A drives a motion, makes once the motion slide block do the reciprocating motion that amplitude is big, frequency is low on two parallel travellers that are fixed on the motion case, and main effect is a scrap fallaway; Power transmission shaft B drives secondary motion mechanism driving saw blade, does with respect to little, the high frequency vibration of amplitude of motion slide block once.The compound motion that motion and secondary motion mechanism produce just can make the cutting edge of saw blade cut under vibrocutting mechanism.When vibrocutting, cutting edge is a pulse cutting force to what be cut that material applies.Cutting edge be cut the continuous dynamic phenomenon identical of generation between the material with the one-shot failure mechanism, i.e. impact → disengaging → impact is cut material and is just changed brittle fracture into form smear metal when not producing plastic deformation.Accompanying drawing 2 is the graphs of a relation of cutting force P (t) and time t under the vibrocutting mechanism, the 1/3-1/5 when the average cutting force of this moment only is common cutting scheme, in addition littler.As spark machined, the mode that Laser Processing etc. utilize thermal pulse to process, vibrocutting is to utilize the power pulse, utilizes energy to cut to peak efficiency.In vibrocutting, vibration produces the rigidization effect, makes vibration electric hand saw, saw blade and the several times when being cut rigidity that part shows and all being equivalent to common cutting, like this, being cut between part and the vibration electric hand saw has staticization effect relatively, makes the vibration electric hand saw be easy to holding operation.Because the rigidity effect, the thin saw blade of the rigidity deficiency that seems when being subjected to continue cutting force has enough rigidity during in vibrocutting.Simultaneously, local oscillator is started the saw blade of composite construction of electric saw the rigidity higher than the saw blade of common single structure when same thickness.Owing to use the high rigidity saw blade of thin composite construction, little to the loss of being cut material, the reducing of cutting output makes cutting force reduce, the reducing and help saw blade unstability not when sawing of cutting force, reduce the coefficient result of effect with the cutting force of vibrocutting mechanism itself, the average cutting force of the average cutting force when making the sawing of vibration electric hand saw during much smaller than common electric hand saw sawing.When the vibration sawing, cutting edge has sharpization effect, promptly show than cutting effect sharper under common cutting scheme, simultaneously, in vibrocutting, the disappearance of constant force Pmean, make heat in metal cutting atomic, can not waste energy, can not cut material production heat damage effect to quilt yet, can not produce built-up edge or sticking tooth phenomenon yet because of the heat fusing of being cut material because of heat in metal cutting because of producing a large amount of heat in metal cuttings.Therefore, saw blade stock-removing efficiency height, not easy to wear, long service life.In sum, because reducing of average cutting force, the raising of stock-removing efficiency, just can use fractional electric motor, requirement to the structural strength of parts is also less, also little by sawing material and active force and the reaction force of vibration between the electric hand saw, thus make that complete machine is in light weight, volume is little, low in energy consumption, be easy to holding operation.The scale mechanism that is made up of scale bar, scale card, scale bar hold-down screw, the tight screw of scale kayser, scale bar axle is installed on the front supported beam, and scale bar can rotate around the scale bar axle.When determining that saw is gone into the sizing sawing of the degree of depth, with the scale bar hold-down screw that scale bar is uprightly fixing, adjusting scale card to predetermined saw is gone into depth dimensions and is used the tight screw lock of scale kayser on scale bar, after saw is gone into desired depth, the scale card with touched by the sawing material, saw blade sawing no longer downwards guarantees the sawing dimensional accuracy;
