Description
Technical field
The utility model belongs to cutting equipment manufacturing technology field, specially refers to a kind of cutter head and the saw blade of this kind of cutter head is installed.
Background technology
Have at present that a kind of one group of saw blade has 80～120 for cutting the lithotome of square shape and artificial stone's saw blade, on a saw blade, be evenly equipped with 28～38 cutter heads, once can cut out 80～120 sheet materials, the thickness 10～20mm of sheet material.The matrix size of above-mentioned saw blade is generally: length 4350mm X height 180mm X thickness 1.6～2.0mm; The size of cutter head is generally: length 20mm X height 9mm X thickness 2.7～3.1mm, there is above-mentioned size known, the solder side length of single cutter head and matrix only has 20mm, and because whole cutter head all contains diamond, after the polishing of the solder side of cutter head, the outstanding diamond of solder side can reduce the weld strength of cutter head and matrix, in cutting process, because weld strength is inadequate, cutter head easily comes off, and causes security incident.In addition, when the height of cutter head is less than 3.2mm, due to the decline of sharpness and weld strength, whole group of saw blade arrives critical point in service life, generally can not continue to use, and caused the waste of part diamond in cutter head.
Summary of the invention
The purpose of this utility model is the saw blade that proposes a kind of cutter head and this kind of cutter head is installed, and the weld strength between this kind of cutter head and saw bit matrix is higher, can improve the utilization rate of cutter head, and can save diamond, reduces costs.
The unique distinction of cutter head of the present utility model is: the top of cutter head is for containing adamantine working lining, and the bottom of cutter head is greater than the length of working lining for not diamantiferous alloy transition layer, the length of described alloy transition layer.
Above-mentioned cutter head utilizes its alloy transition layer and saw bit matrix welding, and alloy transition layer, owing to there is no outstanding diamond, adopts the powder metallurgy sintered body close with the physics and chemistry performance of steel matrix, and its weld strength gets a promotion; And be greater than the length of working lining owing to stating the length of alloy transition layer, so improved the bonding area of single cutter head and matrix, correspondingly also just improved weld strength, in cutting process, cutter head can not come off, and has stopped the generation of security incident; And can be so that the working lining of cutter head can be finished using, finally remaining is there is no adamantine alloy transition layer, has saved a large amount of diamonds, has reduced the cost of product.
Further, described cutter head thickness is reduced to alloy transition layer gradually by working lining, efficiently solves like this problem that the sheet material of cutting is clamped saw blade and cutter head, avoids the quality problems such as sheet material deflection, concentric reducer, fracture.
Further, the vertical cross-section of described alloy transition layer is trapezoidal, and described alloy transition layer is less than the length away from cutter head one side near the length of cutter head one side.Alloy transition layer adopts trapezoid cross section design, can be when enough bonding areas be provided, can also provide the space of enough cooling and deslagging, the normal use of assurance saw blade.
Further, described alloy transition layer and working lining joint rounding off, concentrate to reduce stress, makes the combination between alloy transition layer and working lining more stable.
The saw blade the utility model proposes comprises matrix and cutter head, and key is that described cutter head adopts the above-mentioned cutter head the utility model proposes, and the alloy transition layer of described cutter head and the matrix of this saw blade are welded and fixed.
The utility model, by changing the structure of cutter head, has strengthened the weld strength between cutter head and saw bit matrix, and has improved the utilization rate of cutter head, has saved diamond, has reduced saw blade cost, has good practicality.

Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the partial structurtes schematic diagram of saw blade of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in the figure, the top of the cutter head 1 of the present embodiment is for containing adamantine working lining 11, and the bottom of cutter head 1 is not diamantiferous alloy transition layer 12, and the length of described alloy transition layer 12 is greater than the length of working lining 11; The vertical cross-section of alloy transition layer 12 is trapezoidal, and described alloy transition layer 12 is less than the length away from cutter head 1 one sides near the length of cutter head 1 one sides.
The thickness of cutter head 1 is reduced to alloy transition layer 12 gradually by working lining 11, efficiently solves like this problem that the sheet material of cutting is clamped cutter head 1, avoids the quality problems such as sheet material deflection, concentric reducer, fracture.
The saw blade the utility model proposes comprises matrix 2 and cutter head 1, and key is the above-mentioned cutter head 1 that described cutter head 1 adopts the present embodiment to propose, and the alloy transition layer 12 of described cutter head 1 is welded and fixed with the matrix 2 of this saw blade.
Above-mentioned cutter head 1 utilizes its alloy transition layer 12 and saw bit matrix 2 welding, and alloy transition layer 12, owing to there is no outstanding diamond, adopts the powder metallurgy sintered body close with the physics and chemistry performance of steel matrix 2, and its weld strength gets a promotion; And be greater than the length of working lining 11 owing to stating the length of alloy transition layer 12, so improved the bonding area of single cutter head 1 and matrix 2, correspondingly also just improved weld strength, in cutting process, cutter head 1 can not come off, and has stopped the generation of security incident; And can so that the working lining 11 of cutter head 1 can finish using, finally remaining is not diamantiferous alloy transition layer 12, saved a large amount of diamonds, reduced the cost of product, alloy transition layer 12 adopts trapezoid cross section design, can be when enough bonding areas be provided, the space of enough cooling and deslagging can also be provided, guarantee the normal use of saw blade.
