Description
One, affiliated field:
The utility model relates to a kind of combination flat-cut annular saw.
Two, prior art:
As everyone knows, legend saw is Chinese master craftsman of the Spring and Autumn period invention, apart from modern so that the history in more than 2500 year to be arranged.Singly be the saw of processing round log, through production practices for many years, be transformed into buck saw, the annular saw that is driven by machine power by the manual rifle saw of two people in past manual bow saw, two people, the main force of leading timber processing is a band saw now.From the differentiation of saw timber processing, we are not difficult to find out that saw has two main lines in evolution process: the one,, enhance productivity to machine driving by manually.The 2nd,, saw kerf is narrowed down by wide, improves volume recovery, reduces discarded object----saw foam.But saw rings discarded object saw foam and will produce.The saw foam says it is " white pollution " from the angle of environmental protection, and this is the common recognition of countries in the world.China just proposes the reasonable utilization to the saw foam from the sixties, mainly is as working as the saving of fuel coal.The seventies occurs the particieboard processing industry, part is sawed foam and is used for doing filling and adds material; The eighties occurs bar-producing machine, the saw foam can be used to make charcoal.The nineties, be used to plant packed auricularia auriculajudae, mushroom in a large number.Because the minimizing of timber, some local saw foam has become easy-to-sell goods.In a word, can sell for money, after all still to sawing the comprehensive utilization of foam though saw foam.Owing to transportation or to sawing the decision of various factors such as foam Tree Species Selection.The saw foam does not also have the qualitative commodity that become so far, and now China is except that a spot of saw foam is utilized by people, and most saw foams by burning in vain, though " white pollution " burnt in processing like this, can bring " smoke contamination " again so far.On global angle, want thoroughly to solve the pollution problem of saw foam, answer has only one, and the saw foam is become the higher commodity of economic worth.The saw foam does not have complete qualitative one-tenth Wood products (commodity) so far, and crux is exactly that proverb is said too broken because the saw foam wood-fibred that present sawn timber processes is too short.So, forest product industry as: particieboard, medium-density plate, product such as fiberboard and papermaking wood pulp are not all used.Because the appearance of band saw, sawn timber was processed the epoch of round log with the past with annular saw.What remain now has only round cross cut saw.It is as follows to process the reason that plate, square bar eliminated by band saw with annular saw: 1. annular saw is the radius acting when sawn timber.Therefore, the diameter of round log is greater than 500mm, and the diameter of annular saw must make annular saw itself manufacturing, flat sawing all compare difficulty greater than more than the 1000mm.2. annular saw is when sawing, and is big with the round log contact area, thereby it is big to produce frictional resistance.Reduce work efficiency.3. the annular saw diameter is excessive.Produce the shake pendulum, saw kerf is increased.Cause volume recovery low, surface irregularity.4. annular saw is to use hand feed when sawn timber is produced, and labour intensity is big.Also influence simultaneously the sawn timber flatness.But, with annular saw round log is processed because the wood footpath of round log is lack of standardization, the part that causes does not cut, and at this moment produces a kind of long filament saw foam, at that time the workman to this phenomenon " reeling off raw silk from cocoons ".From sawn timber theoretically, the reason of generation wire drawing is that flat-cut causes.Quarter sawing can " not reeled off raw silk from cocoons ".So present band saw can " not reel off raw silk from cocoons " when processing plate, square bar forever.This long filament saw foam, little to the wood-fibred destructiveness, its length is used for making paper pulp and processing medium density fibre board (MDF) all greater than 5mm, can substitute the raw material wood chip of artificial fully.When the defibrator defibre, want saving of work and time than wood chip.If the saw foam of sawn timber processing all becomes long filament saw foam, long filament saw foam has just really become commodity.The economic worth of itself can be equal to wood chip.If this method can realize that the processing of " no discarded object " sawn timber just may become now, can improve timber utilization rate again simultaneously, really accomplish " eat to do and press only ".Therefore, press at present and develop a kind of aforementioned four defectives of processing plate, square bar existence with annular saw that overcome, overall target is better than band saw again simultaneously, can thoroughly eliminate " white pollution " of saw foam, and can process the combination flat-cut annular saw of long filament saw foam.
Three, summary of the invention:
The purpose of utility model is in order to overcome the technical problem that can not process long filament saw foam that prior art exists, a kind of reasonable in design is provided, the efficient height, the same at power consumption with identical band saw, under the also basic the same situation of productivity ratio, cost is lower than band saw, overall economic efficiency is than higher combination flat-cut annular saw, this combination flat-cut annular saw not only can solve the problem that prior art can not be processed long filament saw foam, and " white pollution " (the belonging to " no discarded object " processing) that can thoroughly eliminate the saw foam, improve timber utilization rate, really accomplish " eat to do and press only ", can overcome and process plate with annular saw, aforementioned four defectives that square bar exists.
The technical solution of the utility model is achieved by following manner: a kind of flat-cut annular saw, comprise frame 4 and on saw cover 3, be installed on the annular saw of frame 4 one ends and the belt pulley 8 of the other end by axle 6, sport car workbench 5, it is characterized in that: said annular saw be designed to successively in three groups and every group on, following annular saw diameter identical in twos to the combination flat-cut annular saw cut (as Fig. 7,8, shown in 9), first, second, the annular saw diameter of the 3rd group of combination flat-cut annular saw successively decreases and successively respectively by annular saw 1 and annular saw 2, annular saw 9 and annular saw 10, annular saw 11 and annular saw 12 are formed (as shown in Figure 7), displacement 7 (displacement 7 as shown in Figure 7 or title displacement H) back is staggered to cutting setting in the center of circle of annular saw 1 and annular saw 2
The annular saw 9 of said second group of combination flat-cut annular saw and the center of circle of annular saw 10 are on same vertical center line, and the center of circle of annular saw 9 and annular saw 10 is respectively above and below the annular saw 1 of first group of combination flat-cut annular saw and the center of circle of annular saw 2, and the diameter of annular saw 9 and annular saw 10 is less than the annular saw 1 of first group of combination flat-cut annular saw and the diameter (as shown in Figure 7) of annular saw 2 simultaneously.
The annular saw 11 of said the 3rd group of combination flat-cut annular saw and the center of circle of annular saw 12 are on same vertical center line, and the annular saw 9 of the center of circle of annular saw 11 and annular saw 12 and second group of combination flat-cut annular saw and the center of circle of annular saw 10 are on same horizontal line and respectively above and below the annular saw 1 of first group of combination flat-cut annular saw and the center of circle of annular saw 2, their diameter is less than the annular saw 9 of first group and second group combination flat-cut annular saw, annular saw 10 and annular saw 11, the diameter of annular saw 12, promptly first, second, the annular saw 1 and the annular saw 2 of the 3rd group of combination flat-cut annular saw, annular saw 9 and annular saw 10, the annular saw diameter of annular saw 11 and annular saw 12 successively decreases successively, as Fig. 7,8, shown in 9.
In the present technique, first group is made up the flat-cut annular saw or be called single group combination flat-cut circular saw designs is upper and lower two annular saws 1 and annular saw 2 to cutting, and upper and lower two centers of circle certain distance that staggers to the annular saw 1 cut and annular saw 2, be to have certain displacement 7 between the center of circle of annular saw 1 and annular saw 2, this first group is made up the flat-cut annular saw or is called list group combination flat-cut annular saw and can use separately under other each situation about organizing be set, as shown in Figure 1, 2, 3; Generally, the structure of first group of combination flat-cut annular saw is constant, and second group of combination flat-cut annular saw is set on this basis, can constitute two groups of combination flat-cut annular saws like this and use separately, shown in Fig. 4,5,6; The structure that also can be first group of combination flat-cut annular saw is constant, second group and the 3rd group combination flat-cut annular saw combination flat-cut annular saw is set on the basis on this basis constitutes three groups of combination flat-cut annular saws and use (shown in Fig. 7,8,9) separately, this is a present technique best-of-breed technology scheme; In like manner, second group, the 3rd group and the 4th group of combination flat-cut annular saw also can be set on first group of combination flat-cut annular saw constitutes four groups of combination flat-cut annular saws (shown in Figure 10,11,12) and uses separately.Certainly, also can be that four groups of above combination flat-cut annular saws use in theory, but design philosophy and principle be basic identical.
The design philosophy of present technique, method and principle are:
1, about the generation of flat-cut, at first analyzes Figure 13, just can clearly obtain answer.When 16 diameters of the round log shown in Figure 13 during greater than the radius of annular saw 1, will produce flat-cuts (perhaps being called flat-cut section 15) in a section 15, produce quarter sawing (non-flat-cut section 17) in b section 17.So it is exactly " long filament saw foam " that a section 15 produces the saw foam, the saw foam that b section 17 produces is exactly common saw foam.Because long filament saw foam is pulverized by b section 17 time, so common annular saw is sawed foam seldom adding the long filament that can see man-hour.
2, determine that about the length of " long filament saw foam " we see Figure 14 earlier, just can obtain the length answer.We learn that annular saw 1 is when processing sawn timber a section by Figure 13, annular saw is in rotation processing, two cuttings 19 mark two ditches with processed timber (a section) earlier, the width of ditch is exactly the parallel width of two cuttings 19, when pushing away tooth 18 and forward the position of (processed timber or round log 16 move forward to) cutting 19 to, push away tooth 18 with release of the wood wool in the ditch and formation long filament saw foam, the length of long filament saw foam is that the cutting of first cutting 19 is sharp to the distance that pushes away crown that pushes away tooth 18 (about 30mm), because the rotation of annular saw is very fast, the radial feed of processed in addition timber or round log 16, so, the length of final long filament saw foam be not first cutting point to push away crown apart from length, but this length about 1/2 or 1/3, more than about 10mm, but this has just satisfied papermaking and the required wood fiber length of medium-density plate.
3, the degree of depth of flat-cut processing (a section 15 height among Figure 13), the degree of depth of flat-cut processing, directly the group number of flat-cut saw is made up in influence, and the factor that the single group of decision flat-cut is sawed working depth has two: the one, the diameter of single group flat-cut saw; The 2nd, the profile of tooth and the tooth of single group flat-cut saw are long.Diameter, profile of tooth, long size, the angle of tooth will could be determined through experiment.
4, combination flat-cut saw schematic diagram, as first group of Figure 15 or be called single group of (one group) flat-cut circular saw designs and analyze schematic diagram, thickness of its maximum processing sawn timber is 2a.Figure 16 is that three groups of flat-cut circular saw designs are analyzed schematic diagram, and combination flat-cut saw processing log diameter is: the 3rd group of 2a of the 2nd group of 2a+ of log diameter=first group 2a+.Reason is, the combination flat-cut is sawed every group of saw blade diameter difference, and a value is difference also.
The comparative analysis of combination flat-cut annular saw and common annular saw:
Four reasons that annular saw is eliminated by band saw have been summed up in the front, and still, combination flat-cut saw has overcome four shortcomings of common annular saw fully on design principle.1, combination flat-cut saw is to cutting sawn timber, so process the round log of same diameter, the greatest combined saw blade diameter of combination flat-cut saw is 1/2 of an annular saw diameter.Like this manufacturing, the flat sawing of saw blade are all ensured the quality of products easily.2, combination flat-cut saw adds man-hour at sawn timber, is the layering sawing, and therefore single group saw blade resistance is little, the work efficiency height.Because combination flat-cut saw diameter is little, so frictional resistance is little.3, combination flat-cut saw diameter is little, and it is less to produce the shake pendulum, and saw kerf is less than common annular saw.4, combination flat-cut saw adopts the carriage feed mode identical with band saw.So alleviated labor strength, improved productivity ratio.In a word, combination flat-cut saw is " no discarded object " processing when sawing is produced, and this point is produced the band saw of usefulness now and can't be compared with combination flat-cut saw.
The economic analysis contrast:
Volume recovery is calculated:
For example: Φ 570mm round log, 4m is long, ≌ 1m
3If timber is this round log processing 25mm sheet material.If: band saw saw kerf: 2.5mm, combination flat-cut saw saw kerf 3mm
Ask the surplus value:
Φ 570 ÷ (25+2.5)=20.7 block hair plates
Φ 570 ÷ (25+3)=20.357 block hair plates
Long from result of calculation: Φ 570 round log 4m, saw 25mm hair plates material, the volume recovery of two saws is the same.
Residue calculates: the round log calculation of complex, and use square bar instead and calculate.
For example: 500 * 500 flitches, the sheet material of processing 25mm.If: band saw saw kerf: 2.5mm, combination flat-cut saw saw kerf: 3mm
Band saw processing: 500 ÷ 27.5=18 pieces are surplused 0.18
The processing of combination flat-cut saw: 500 ÷ 28=17 pieces are surplused 0.86
Band saw: 0.18 * 25=4.5mm of residue material sheet material, one of surplus thin plate
Combination saw: 0.86 * 25=21.5mm of residue material sheet material,
The combination saw residue goes out one 20 plate, few one 25 plate.
Band saw: saw foam 1m
3-(0.025 * 0.5 * 18 * 4+0.0045 * 0.5 * 4)
=1m
3-(0.9m
3+0.009m

Combination saw: saw foam 1m
3-(0.025 * 0.5 * 17 * 4+0.02 * 0.5 * 4)
=1m
3-(0.85m
3+ 0.04m
3)=0.11m
3(saw foam)
Band saw: 0.091m
3The saw foam is burnt.
Combination saw: 0.11m
3The saw foam becomes Wood chips for the pulp.
0.11m
3* 2.8 lamination rice * 115 yuan/m
3=35.42 yuan
0.11m
3The wood wool of * 2.8 lamination rice=0.3 lamination rice
Chip separately cost=0.3 * 10 yuan of 0.3 lamination rice=3 yuan.
Residue is worth: 35.42 yuan+3 yuan=38.42 yuan.
Material is identical, and the 20mm plate that length and width are the same is slightly higher than 25mm plate price.So it is identical substantially that 17 blocks of plates of 18 blocks of plates of band saw processing and the saw processing of combination flat-cut add its economic worth of a 20mm plate.
In sum, combination flat-cut saw is compared with prior art, promptly compare with band saw, we are not difficult to find out that the economic benefit of combination flat-cut saw aspect sawn timber processing of " no discarded object " processing is very clear, and power consumption is the same with identical band saw in combination flat-cut saw institute, under the also basic the same situation of productivity ratio, have the combination flat-cut and be sawn into that this is lower than band saw, belong to " no discarded object " processing, characteristics such as overall economic efficiency is higher.
