Fig. 1～Fig. 7 is the example that relates to blade saw for cutting of the present invention.As shown in Figures 1 and 2, blade saw for cutting 1 (becoming butcher's saw 1) is provided with discoideus and has formed the parent metal dish 2 in a plurality of light weights hole 3, 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 par 2a of Rack in the outside of installing hole 4; In the outside of this par 2a, formed towards segment difference section 2b as the below tilted direction projecting height size h shown in Figure 2 of anti-cutting machine 5 sides, simultaneously, formed smooth blade part 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 part 2c, will be set at parallel (same direction) with par 2a as blade 7 directions (projected direction laterally) of blade.
In addition, on parent metal dise knife blade 2c top, blade carrier (briar tooth) 8 and blade installation portion 9 (with reference to Fig. 3) have been formed according to certain interval; On each blade installation portion 9, the described blade 7 that is made of superhard alloy has been installed by solder brazing.At this moment, as Fig. 3～shown in Figure 5, blade 7 is provided with front 7a and top end face 7b and 4 installed surface 7c～7f, simultaneously, in the thickness direction both sides of 3 installed surface 7c～7e, has formed respectively and has seen L-shaped a little handguard 7g from the side.In addition, tackle the shape of this blade 7 each installed surface 7c～7f, described blade installation portion 9 has formed concave shape.
Then, described blade 7 is installed on the blade installation portion 9 of parent metal dish 2 by solder brazing according to following form.Promptly, blade 7 is inserted on the blade installation portion 9 of parent metal dish 2 from diagram arrow イ direction, thereby form shown in Figure 4, parent metal dish 2 is sandwiched in the state between a pair of handle 7g of blade 7, in this state, the inboard of 4 installed surface 7c～7f and a pair of handle 7g is fixed by solder brazing.So, the solder brazing area of the blade installation portion 9 of phase blade 7 will significantly enlarge.In addition, as shown in Figure 4, be installed in the blade 7 on the blade installation portion 9 of parent metal dish 2, the part of its handle 7g is from the outstanding given size in two sides of parent metal dish 2, and this is of a size of sawtooth outstanding width w1, w2.
Next, an example of the manufacture method of described butcher's saw 1 is described according to the engineering drawing of Fig. 6.About butcher's saw 1, the processing of the extrusion process by punching press (K01) parent metal dish blank rough stocks such as () carbon steel plates at first, being shaped is provided with the blade part 2c of described par 2a and segment difference section 2b and blade 8 or blade installation portion 9.Then, utilize for example this parent metal dish 2 of high-frequency induction heating quenching, by the heat treatment (K02) of annealing.When carrying out this heat treatment, by under the heating pressurized state, carrying out the processing of parent metal dish 2, prevent the perk of par 2a and blade part 2c etc., form the par 2a and the blade part 2c that are parallel to each other.
The heat treatment of parent metal dish 2 for example, is carried out surface treatment (K03) by bead after finishing, and after this surface treatment finishes, for example utilizes the high-frequency induction heating that blade 7 is installed on each blade installation portion 9 of parent metal dish by solder brazing (K04).Then, (K06) handled in the grinding (K05) of front 7a, top end face 7b by carrying out blade 7 and two sides etc., fine finishining, produces butcher's saw 1.Promptly, described butcher's saw 1 by under the heating pressurized state to solder brazing the parent metal dish 2 of front of blade 7 heat-treat, perk can guarantee that par 2a and blade part 2c are in parastate because rebound can to prevent par 2a or blade part 2c.
The butcher's saw 1 of Xing Chenging cuts by sawing and to stop cover plate 5c, saw control flange 5d and construction bolt 10 as shown in Figure 7 like this, is installed on the saw support lugn on rotating shaft 5a top of cutting machine 5.During installation, snap on the saw support lugn 5b by face the anti-blade part 2c side of butcher's saw 1 par 2a, make construction bolt 10 be positioned at the recess 6 of butcher's saw 1, at this moment, height dimension h by segment difference section 2b makes the head of construction bolt 10 be positioned at recess 6, and (in Fig. 7 below) is outstanding not laterally.
In addition, the given size of the width of butcher's saw 1 par 2a (effectively flat width) is set greatlyyer than the external diameter of the saw support lugn 5b of cutting machine 5, and par 2a forms the state of the entire flange face that fits tightly saw support lugn 5b.Under this installment state, by operation cutting machine 5 rotating knife blade saws 1, like this, the blade 7 of this blade part 2c will become the state (for example) that roughly at right angles enters with weedtree, therefore can successfully cut weedtree.
But, under the installment state that cutting machine 5 is installed, for example, as shown in Figure 8, also the bolt cover sheet can be installed in the recess 6 shown in Figure 7.At this moment, for example, also can push down the outer peripheral edges portion of the bolt cover sheet 11 that roughly is the dish shape and install by saw control flange 5d etc.In addition, in the bottom of bolt cover sheet 11, form as required and make this cover sheet self annular recessed portion 11a of rotation smoothly.
Like this; according to described butcher's saw 1; the blade part 2c that parent metal dish 2 is equipped with par 2a and segment difference section 2b and extends in parallel with par 2a; when the height dimension of segment difference section 2b is installed to cutting machine 5 than by construction bolt 10 with par 2a; the outstanding size of this construction bolt 10 is big; therefore; on the 2a of the par of parent metal dish 2, form circular recess 6 by segment difference section 2b; can protect construction bolt 10 and suppress the wearing and tearing of bolt head or distortion etc. by this recess 6; butcher's saw 1 is installed to cutting machine 5 or when cutting machine 5 is pulled down butcher's saw; construction bolt 10 can be operated well, the replacing operation of butcher's saw 1 can be successfully carried out.
In addition, because set parallel with par 2a influences the blade part of cutting performance 2c, so can prevent from butcher's saw in the past, to take place, as having angle between the blade 7 of blade and the par 2a (to the installed surface that cutter 5 is installed), cause blade 7 to enter problems such as weedtree sideling, blade 7 can at right angles enter with summaries such as weedtrees among the present invention, can easily obtain good cutting performance on butcher's saw 1.In addition; if the bolt cover sheet 11 that covers construction bolt 10 is installed on the recess 6 of 2b inboard, segment difference section by par 2a; just can protect head of construction bolt 11 etc. so by this bolt cover sheet 11 more effectively, can more successfully carry out the replacing operation of butcher's saw 1 on cutting machine 5 etc.
And, owing to formed handguard 7g respectively in the both sides aspect blade 7 thickness, so can enlarge the solder brazing area of the blade 7 of phase blade installation portion 9 by both sides handguard 7g, the installation strength that can significantly improve blade 7 suppresses it and comes off, simultaneously, for example can itself guarantee enough big front 7a etc., can carry out the grinding again of blade 7 etc., can suppress the reduction of butcher's saw 1 cutting performance and prolong its life-span at blade 7.
In addition, owing to see that from the side the handguard 7g of blade 7 is L-shaped a little, therefore can be easily to blade installation portion 9 embeddings of blade 7, simultaneously, the size of space between a pair of handguard 7g is set at roughly identical with parent metal dish 2, thereby fundamentally determined the position relation of blade 7 and parent metal dish 2, can be simply and set described outstanding size w1, w2 etc. effectively, the efficient of solder brazing operation or grinding operation etc. can be improved, the cost of butcher's saw 1 can be made every effort to reduce.
And, according to test, under the situation of described butcher's saw 1, on parent metal dish 2, formed recess 6 by segment difference section 2b, and all have described specified altitude h also at intervals to the par 2a of the installed surface of cutting machine 5 installations as the blade 7 of blade with as butcher's saw 1, therefore, when cutting operation, weeds etc. can not twine the rotating shaft part of cutting machine 5 basically, determine to obtain good cutting performance on butcher's saw 1.
This relatively situation, for example, on butcher's saw in the past 101 shown in Figure 10, as the par 102a of cutting machine 104 installed surfaces and blade at grade, therefore.For example be rolled onto the rotating shaft part of cutting machine 104 for weeds of preventing to cut down etc., installed in cutting machine 104 sides of rotating shaft part and to have prevented the discoid plate (not having diagram) that prevents that is involved in, but be difficult between the rotary shaft of the blade of butcher's saw 101 and cutting machine 104 divides, guarantee sufficient size, therefore be difficult to guarantee that butcher's saw 101 has good cutting performance.
In addition, butcher's saw 1 is produced by following operation: the operation of punch process parent metal dish blank, shaping par 2a and segment difference section 2b and blade part 2c; Heat treatment is in the operation of the parent metal dish 2 of this operation acquisition; Operation of solder brazing blade 7 etc. after this heat treatment; therefore; can protect construction bolt 10 and suppress wearing and tearing of bolt head etc.; can change operation etc. to cutting machine 5 smoothly; can prevent the perk of blade part 2c, can be easily and produce the butcher's saw 1 of good cutting performance with cheap price.Particularly, by the operation of under the heating pressurized state, heat-treating, therefore parallel setting par 2a and blade part 2c can easily guarantee the depth of parallelism of par 2a and blade part 2c can obtain the better butcher's saw 1 of cutting performance with cheap price.
And in described example, blade 7 has formed 4 installed surface 7c～7f, but the present invention is not limited thereto, for example, also can constitute shown in (b) as Fig. 9 (a).That is, (a) blade 7 shown in has 3 installed surface 7c～7e, and handguard 7g has formed the side and seen the shape that is L in the both sides of installed surface 7c, 7d.In addition, (b) shown in blade 72 installed surface 7c, 7d are arranged, handguard 7g has formed the side and has seen the shape that is L in the both sides of installed surface 7c, 7d.Like this, the blade 7 that uses on butcher's saw 1 of the present invention is so long as there is installed surface more than 2, and has the form of handguard 7g to get final product respectively for its both sides.
In addition, in described example, par 2a and the completely parallel situation of blade part 2c have been described, but par 2a of the present invention and blade part 2c can be almost parallels within the possible range, roughly at right angles enter as long as can guarantee relative weedtree of blade etc.In addition, in described example, the width of the par 2a of the number of blade installation portion 9 or shape, parent metal dish 2 or the height dimension h of segment difference section 2b etc. are an example all, in the scope that does not break away from aim of the present invention, can adopt appropriate structures.
The present invention can be applicable on discoideus parent metal dise knife blade top blade has been installed, and is used to cut all blade saw for cutting of weeds etc.
In sum, be preferred embodiment of the present invention only, be not to be used for limiting practical range of the present invention, promptly all equivalences of doing according to the content of the present patent application claim change and modify, and all should be technology category of the present invention.
