Description
Technical field
The present invention relates to be installed on the cutting machine blade saw for cutting and the manufacture method thereof when cutting weeds or weedtree etc. (hereinafter referred to as weedtree etc.), used.
Background technology
In the past, as incisory butcher's saw, for example, Fig. 8 and butcher's saw shown in Figure 9 be well-known.As shown in Figure 8, this butcher's saw 101 has formed on the par 102a of discoideus parent metal dish 102 cores to cutting machine 104 installing hole 103 of usefulness has been installed, simultaneously, in the outer periphery of par 102a, formed the circular expanding section 102b that expands downwards.In addition, in the expanding section of the parent metal dish 102 102b outside, blade part 102c is perk state backward towards described par 102a direction.
Then, shown in Fig. 9 (a) and (b), on the blade installation portion 105 on the blade part 102c top of parent metal dish 102, by solder brazing the blade 106,107 that is provided with front 106a, 107a and top end face 106b, 1407b has been installed respectively.That is, blade installation portion 105 sections of being of Fig. 9 (a) differ from shape, and two installed surface 106c, 106d of blade 106 have been installed by solder brazing respectively on this blade installation portion 105.In addition, the blade installation portion 105 of Fig. 9 (b) is the chase shape, sees the installed surface that is half-circle-arc shape by what blade 107 had been fixed in solder brazing from the plane by what three installed surface 107c～107e constituted on this blade installation portion 105.And, as the butcher's saw by the solder brazing fixed blade, for example, open in Patent Document 1 (opening flat 06-24429 communique in fact) on parent metal dise knife blade top.
But, although this butcher's saw 101 have can in the recess of 102b inboard, expanding section, set to cutting machine 104 install usefulness construction bolt 108, can prevent that thereby construction bolt 108 heads are to exposing outside advantages such as controlling its wearing and tearing or distortion, be installed in blade 106,107 (blade) on the parent metal dish 102 blade part 102c but also exist, the problem of cutting performance differences such as its cutting weedtree by solder brazing.
Promptly, described butcher's saw 101, its manufacture method that adopts is after blade 106,107 is installed to the blade part 102c of parent metal dish 102 by solder brazing, shape expanding section 102b by punching press (extruding), therefore, the resilience meeting of parent metal dish 102 causes forming 102b lateral, the expanding section top perk of parent metal dish 102, sees Fig. 8.Consequently, there is angle in par 102a as the relative parent metal dish 102 of projected direction of the blade 106,107 of blade, can't form roughly on unidirectional plane with par 102a, so blade is difficult to the right angle and enters weedtree etc., thereby cause its cutting performance poor.
In addition, be installed in the blade 106,107 on the blade installation portion 105 of parent metal dish 102 by solder brazing, if carry out solder brazing according to form shown in Fig. 9 (a), though can guarantee front 106a so significantly as the blade 106 of cutting edge, but solder brazing area (fixed-area) is less, and blade 106 comes off easily.On the contrary, if carry out solder brazing according to form shown in Fig. 9 (b), though can strengthen the solder brazing area to a certain extent so, but the area as the front 107a of the blade 107 of cutting edge just diminishes easily, for improving cutting performance, just need skive blade 107 once more, the result can cause being difficult to prolonging the life-span of butcher's saw 101 etc., because the butcher's saw 101 of which kind of form all cuts both ways.
In addition, when carrying out the cutting operation of weedtree etc., operator's power can be asked the root that cuts off weedtree etc., blade 106,107 as blade just enters the first-class below of gravelstone easily like this, thereby cause that gravelstone is first-class to pop up or blade 106,107 damages and causes separation of fragments, to such an extent as to personal injury may take place the operator.Because the force direction that butcher's saw 101 is born has nothing in common with each other, so the generally following multiple reason stack of these accidents causes that for example, the revolution of butcher's saw 101 causes the resonance of parent metal dish 102; Or the vibrations of butcher's saw 101 itself cause alternate stress to focus on flange section, and this flange section is the installation portion of installing to cutting machine 104, chaps to parent metal dish 102 from this mounting portion; Butcher's saw 101 comes off etc. from cutting machine 104, and from security standpoint, parent metal dish 102 itself needs the intensity of certain bending stress.
Summary of the invention
The object of the present invention is to provide a kind of blade saw for cutting and manufacture method thereof, when fully improving the bending stress of parent metal dish, can reduce as far as possible that gravelstone is first-class upsprings upward, and security is superior, blade can enter weedtree etc. in the right angle, can easily obtain good cutting performance.In addition, except that above-mentioned purpose, other purpose is the solder brazing area of the blade installation portion on the relative parent metal dise knife of increased blade blade top, and can guarantee enough big front, reduce problems such as blade comes off, further improve security in, the decline of control cutting performance also increases the service life.

The specific embodiment
Describe in detail according to drawing below and carry out form of the present invention.
Fig. 1～Fig. 5 is the example that relates to blade saw for cutting of the present invention.As Fig. 1～shown in Figure 3, blade saw for cutting 1 (being called butcher's saw 1) is provided with discoideus and has formed the parent metal dish 2 of a plurality of lightweights hole 3a, 3b, has formed aftermentioned in the center of this parent metal dish 2 and to cutting machine 5 installing hole 4 of usefulness has been installed.
In addition, parent metal dish 2 has formed the installation par 2a of Rack in the outside of installing hole 4; In this outside that par 2a is installed, formed the segment difference section 2b that is of a size of h1 towards projecting height as anti-cutting machine 5 sides, simultaneously, formed blade par 2c in the outside of this segment difference section 2b.Then, on parent metal dish 2, formed from described segment difference section 2b and seen rounded space shape recess 6 to its inboard, simultaneously, by parallel formation par 2a and blade par 2c are installed, will be set at parallel (unidirectional plane) with installation par 2a as blade 7 directions (projected direction laterally) of blade.
In addition, on parent metal dise knife sword par 2c, formed the protuberance 8 that a plurality of (among the figure being 10) and installing hole 4 are concentric circles according to certain intervals.As shown in Figure 3, each protuberance 8 roughly is hemispherical, apart from blade 7 tops apart from more than the size L=15mm, and formed the height of sphere diameter d 1/5～1/3 (1/4 is ideal), therefore, the outstanding size apart from blade par 2c is set at h2=5～7mm.Outstanding size h2 by protuberance 8 or apart from the setting of size L as described later, in the rigidity of guaranteeing protuberance 8 itself, has suppressed that gravelstone is first-class upsprings upward.
And, outer peripheral edges at described parent metal dish 2---2c top, blade par, form a plurality of blade carriers (briar tooth) 10 and blade installation portion 11 (with reference to Fig. 1) according to certain intervals, on each blade installation portion 11, fixed the described blade of forming by superhard alloy 7 by solder brazing.At this moment, blade 7 has formed front 7a and top end face 7b and 4 installed surface 7c～7f as shown in Figure 4, has formed by the thickness direction both sides at 3 installed surface 7c～7e and has seen the handguard 7g that roughly is the L word shape from the side.In addition, the shape for to each installed surface 7c～7f that should blade 7 has formed concave shape on the described blade installation portion 11.
Described blade 7 is as described below to be welded on by solder brazing on the blade installation portion 11 of parent metal dish 2.Promptly, arrow イ direction according to figure (4) is inserted into blade 7 on the blade installation portion 11 of parent metal dish 2, therefore, parent metal dish 2 is sandwiched between a pair of handguard of blade 7, in this state, the two sides 2d shown in Fig. 4 (b) is fixed by solder brazing respectively on the inner face of 4 installed surface 7c～7f and blade installation portion 11 and 1 couple of handguard 7g and the parent metal dish 2.Therefore, the solder brazing area of blade 7 phase blade installation portions 11 has just significantly enlarged.In addition, be fixed on the blade 7 on the blade installation portion 11 of parent metal dish 2, the part of its handguard 7g is from the outstanding given size in the two sides of parent metal dish 2, and this is of a size of outstanding size.
The butcher's saw 1 of this formation is produced by following operation.Promptly, at first, behind the ram extrusion processing parent metal dish blank (raw material of carbon steel plate etc.), be formed with the described installation par 2a of installing hole 4, with segment difference section 2b, blade carrier 10, blade installation portion 11 and the blade par 2c that is provided with lightweight hole 3a, 3b and protuberance 8.When extrusion process, as shown in Figure 2, each size of described recess 6 is set as follows: the R that the R of blade par 2c side is R1=4～10mm (5mm is ideal), install par 2a side is that R2=5～15mm (6mm is ideal), the diameter that par 2a is installed are that the diameter of Φ 1=85mm, recess 6 is Φ 2=125mm etc.By the setting of these sizes,, and can suppress vibration or the swing of blade par 2c even the parent metal dish blank that extrusion process is made up of carbon steel plate etc. also can prevent cracking of recess 6 parts etc.
After processing parent metal dish blank has been made parent metal dish 2, for example this parent metal dish 2 is quenched the heat treatment of annealing simultaneously by the high-frequency induction heating.When this heat treatment, parent metal dish 2 carries out under the pressurized state in heating, therefore can prevent to install the reflex action of par 2a and blade par 2c etc., forms the installation par 2a and the blade par 2c that are parallel to each other.The heat treatment of parent metal dish 2 for example, is carried out surface treatment by bead after finishing, and for example by the high-frequency induction heating blade 7 is welded on each blade installation portion 11 of parent metal dish 2.
Then, the grinding of front 7a, top end face 7b by carrying out blade 7 and two sides etc. and fine finishining are handled, and make butcher's saw 1.Promptly, described butcher's saw 1 is before solder brazing welding blade 7, under the heating pressurized state parent metal dish 2 heat-treated, therefore, can prevent to install par 2a and the 2c reflex action of blade par by resilience, and par 2a can be installed is parallel state with blade par 2c.
The butcher's saw 1 of Gou Chenging stops cover plate 5c, presses blue 5d of sawing and construction bolt 9 to be installed in holding on the blue 5b of sawing as the rotating drive shaft 5a top of cutting machine 5 by saw cut as shown in Figure 5 like this.During installation, the installed surface 2a of butcher's saw 1 is snapped on the face that holds the blue 5b of sawing of cutting machine 5, and then construction bolt 9 is positioned at the recess 6 of butcher's saw 1, at this moment, according to the height dimension h1 of segment difference section 2b, the head of construction bolt 9 is arranged in recess 6 can not be projected into the outside (Fig. 5 is the below).
In addition, the width of the installation par 2a of butcher's saw 1 (effectively par width, be described size Φ 1) given size set than cutting machine 5 to hold the blue 5b external diameter of sawing big, par 2a is installed forms the state that fits tightly with the flange face integral body of holding the blue 5b of sawing.Under this installment state, make cutting machine 5 action rotating knife blade saws 1, the blade 7 on this 2c top, blade par will become the state that slightly at right angles enters weedtree etc. so, thereby can successfully cut off weedtree etc.
Fig. 6 is the bending stress measurement result figure that shows parent metal dish 2 on the described butcher's saw 1.As shown in Figure 7, at this moment bending stress measuring method is as follows, for the measurement test piece S1 of the described parent metal dish 2 of present patent application invention and the measurement test piece S2～S5 of the tabular parent metal dish that 4 kinds do not have segment difference section 2b, the outer peripheral edges of each test piece S1～S5 are placed on the circular brace table 13, and with each measure test piece S1～S5 be fixed on utilize its installing hole 4 can access regulation test power (unit: diameter thousand newton) is the lower end of the anchor clamps 14 of 70mm.Then, the test power that makes anchor clamps 14 descends when changing, according to each pilot strength measurement measure the stroke (deflection) of test piece S1～S5.
As shown in Figure 6, found that according to it: for example, relatively stroke (deflection) is the test power of 1.2mm, and the measurement test piece S1 of present patent application invention compares other and measures test piece S2～S5 so, needs about bigger test power more than 3 times.That is to say, the parent metal dish 2 of present patent application invention (measuring test piece S1) is compared does not have the tabular of segment difference section 2b parent metal dish (measurement test piece S2～S5), its bending stress significantly improves, for example, and phenomenons such as resonance in the time of can effectively suppressing to rotate at a high speed or swing.
Like this; according to described butcher's saw 1; parent metal dish 2 possesses the par 2a of installation and segment difference section 2b and blade installation portion 2c; in the time par 2a will be installed by construction bolt 9 be installed on the cutting machine 5; the height dimension h1 of segment difference section 2b sets greatlyyer than the outstanding size of this construction bolt 9; so recess 6 that on the 2a of the installation par of parent metal dish 2, forms by segment difference section 2b; can protect construction bolt 9 and reduce the wearing and tearing or the distortion of head by this recess 6; butcher's saw 1 is installed on the cutting machine 5 or when cutting machine 5 is pulled down butcher's saw 1; the rotary manipulation construction bolt 9 well, therefore can successfully carry out the replacing operation of butcher's saw 1.
In addition, influence the blade par 2c and the parallel setting of installation par 2a of cutting performance, therefore, the same with usual model, as the blade 7 of blade with install between the par 2a (to the installed surface that cutting machine 5 is installed) and have angle, can prevent that blade 7 from entering weedtree etc. sideling, can make blade 7 slightly at right angles enter weedtree etc., thereby make butcher's saw 1 easily obtain good cutting performance.
In addition, because on the 2c of the blade par of parent metal dish 2, a plurality of protuberances 8 have been formed according to certain intervals, therefore during cutting operation by making these protuberance 8 kiss the earths prevent blade 7 direct kiss the earths, thereby can prevent that blade 7 from entering into the first-class downside of gravelstone, the present invention can not only suppress the first-class phenomenon of upspringing upward of gravelstone that blade 7 causes, can also by protuberance 8 itself with the first-class back side of gravelstone (ground plane) at parent metal dish 2 forwards or the side eject.Personal injury in the time of consequently can preventing to upspring the cutting operation that causes upward etc. because of gravelstone is first-class, the security in the time of can improving cutting operation.
Particularly since the outstanding size h2 of protuberance 8 or apart from size L all according to aforementioned content setting, therefore can cut off weedtree etc. conscientiously at suitable height and position by blade 7, and keep certain cutting performance well, also can really prevent the first-class phenomenon of upspringing upward of gravelstone that blade 7 causes simultaneously.In addition, protuberance 8 relative 3～5 blades 7 form 1, and therefore the number with protuberance is set at optimal number, and can obtain satisfying simultaneously the butcher's saw of security and cutting performance easily.
In addition, the height dimension of protuberance 8 is set at 1/5～1/3 of sphere diameter d, therefore can guarantee to make protuberance itself to have enough rigidity, thereby can prevent its distortion, simultaneously, number by protuberance 8 is set, and can make the vibration of operator's imperceptible protuberance 8 that contacts with ground from the rotation by parent metal dish 2 when cutting operation as far as possible.In addition, can further improve the operation and the security of cutting operation, for example, can reduce the rotating shaft part that weeds etc. are wound into cutting machine 5, or can make by recess 6 that gravelstone is first-class to splash to the side etc. by segment difference section 2b.
And, owing to formed handguard 7g respectively in the both sides of blade 7 thickness directions, therefore by handguard 7g can increased blade 7 phase blade installation portions 9 the solder brazing area, significantly improved the constant intensity of blade 7 and can suppress it and come off, simultaneously, for example, can itself guarantee enough big front 7a at blade 7, thereby skive blade 7 etc. can be controlled the decline of butcher's saw 1 cutting performance and prolong its life-span once more.
In addition, see from the side, the handguard 7g of blade 7 slightly is the L word shape, therefore can inlay like a cork on the blade installation portion 9 of blade 7, simultaneously, roughly identical with parent metal dish 2 by the size of space between a pair of handguard 7g is set for, fundamentally determine the position relation of blade 7 and parent metal dish 2, can be simply and set outstanding size etc. effectively, the efficient of solder brazing operation or grinding operation etc. can be improved, and the cost of butcher's saw 1 can be made every effort to reduce.
In addition; butcher's saw 1 is behind punch process parent metal dish blank; produced by par 2a and the operation of segment difference section 2b and blade par 2c, the operation that solder brazing is carried out blade 7 in the operation of the parent metal dish 2 that this operation obtains, after this heat treatment in heat treatment etc. be shaped to be installed, therefore can easily and with cheap cost obtain: can protect construction bolt 9 minimizing heads wearing and tearing etc., can carry out the replacing operation to cutting machine 5, the reflex action that can prevent blade par 2c, butcher's saw 1 that cutting performance is good smoothly.
Particularly when the extrusion process of parent metal dish blank, R size R1 with recess portion 6, R2 etc. are set at aforementioned dimensions, even what parent metal dish blank used like this is carbon steel plate, also can prevent to add recess cracking of 6 in man-hour etc., can do one's utmost to control the cost rising of parent metal dish 2, simultaneously, by under the heating pressurized state, heat-treating, par 2a will be installed to be set at parallel with blade par 2c, therefore can be easily and guarantee to install the depth of parallelism between par 2a and the blade par 2c conscientiously, can produce the better butcher's saw 1 of cutting performance with cheap price.
In addition, in described example, blade 7 has formed 4 installed surface 7c～7f, but the present invention is not limited thereto, also can be the form that the installed surface more than 2 is arranged and be respectively equipped with handguard 7g in its both sides.In addition, in described example, installation par 2a and the completely parallel situation of blade par 2c have been described, but installation of the present invention par 2a and blade par 2c can be almost parallels, at right angles enter weedtree etc. as long as can omit.And, in described example, the width of the installation par 2a of the number of blade installation portion 11 or shape, parent metal dish 2 or the height dimension h1 of segment difference section 2b etc. all are examples, in the scope that does not break away from the aim of each invention among the present invention, can adopt appropriate structures.
