Abstract
The utility model discloses a kind of high strength low noise diamond circular saw film base body, comprise saw bit matrix, centre bore is provided with in the center of saw bit matrix, the cylindrical of upper and lower two sagittal planes of saw bit matrix offers uniformly at intervals partly penetrate tank, the degree of depth partly penetrating tank is the half of saw bit matrix thickness.Be provided with cutter head at every two adjacent sawtooth formed between tank that partly penetrate, all cutter heads being positioned at same sagittal plane form a circle; Namely on the upper sagittal plane and lower sagittal plane of whole matrix, a circle cutter head is all provided with.The high strength low noise diamond circular saw film base body that the utility model provides, has following beneficial effect: 1. add supplemental support, increases incision stability.2. because tank is partly penetrate tank, then cutter head incision thickness reduces by half, and reduces incision and impacts.3. optimize sawtooth stressed, improve fatigue life.4. reduce the modal density of diamond circular saw film base body, reduce radiated noise.
Description
Technical field
The utility model relates to a kind of high strength low noise diamond circular saw film base body, belongs to cutting tool technical field.
Background technology
Diamond disc is widely used in the cutting of stone material, pottery, concrete etc.Traditional diamond circular saw film base body as shown in Figure 4, cylindrical has equally distributed sawtooth, have between each sawtooth " U " shape or " R " shape penetrability tank.Sawtooth periodically cuts out as interrupted process, bears larger impact in cut process, and working angles is unstable, and tooth Root Stress is concentrated, and easily occurs fatigue crack.This external flume cuts off the periphery of saw blade, makes n=ks/2 or n=ks (k=1,2,3 of matrix ...) pitch diameter mode isolated, and increases the modal density of matrix, increases the radiated noise of matrix.
Utility model content
The purpose of this utility model is, provides a kind of high strength low noise diamond circular saw film base body stablizing cutting, can reduce the impact in process, realizes stable cutting; Reduce the modal density of matrix simultaneously, reduce the radiated noise of matrix further.
The purpose of this utility model is achieved in that
A kind of high strength low noise diamond saw blade substrate, comprises saw bit matrix, is provided with centre bore in the center of described saw bit matrix, and the cylindrical of upper and lower two sagittal planes of saw bit matrix offers non-penetrating type tank uniformly at intervals.
Described non-penetrating type tank is semi penetration type tank, and its degree of depth is the half of saw bit matrix thickness; The described degree of depth partly penetrating tank be from saw bit matrix facing radially towards lower or little facing radially towards on to the position of matrix thickness half.
Be provided with cutter head at every two adjacent sawtooth formed between tank that partly penetrate, all cutter heads being positioned at same sagittal plane form a circle; Namely on the upper sagittal plane and lower sagittal plane of whole matrix, a circle cutter head is all provided with.
On the sawtooth of described cutter head welding.
Described partly penetrates tank, and its shape is U-shaped, R shape or semicircle.
The high strength low noise diamond circular saw film base body that the utility model provides, has following beneficial effect:
1. add supplemental support, increase incision stability.Uniform tank on traditional diamond circular saw film base body periphery is changed into both sides uniformly at intervals partly penetrate tank, during the incision of next sawtooth, the sawtooth of side is stable to be cut, and is equivalent to side and adds a supplemental support, increase the stability of cut process, realize continous-stable and cut.
2. because tank is partly penetrate tank, then cutter head incision thickness reduces by half, and reduces incision and impacts; Be only original half during cutter head incision, impulsive force reduces, and increases the stability of cutting, and reduces radiated noise.
3. optimize sawtooth stressed, improve fatigue life.The former tank penetrating shape, tooth Root Stress is concentrated serious, and diamond circular saw sheet matrix, its tank is non-penetrating type, and whole tank sidewall is stressed, the power dispersion that sawtooth is subject to, and reduces tooth Root Stress and concentrates.The phenomenon that tooth Root Stress is too concentrated is eliminated, and improves the resistance to impact of saw bit matrix.
4. reduce the modal density of diamond circular saw film base body, reduce radiated noise.Avoid, because tank cuts off the discontinuity of the diamond circular saw film base body periphery of causing, suppressing matrix n=ks/2 or n=ks (k=1,2,3 ...) pitch diameter mode isolates, and reduces the modal density of matrix, reduces the radiated noise of matrix.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model comprises saw bit matrix 2, saw bit matrix 2 is provided with centre bore 1, centre bore 1 is provided with in the center of saw bit matrix 2, the cylindrical of two sagittal planes of saw bit matrix about 2 offers uniformly at intervals partly penetrate tank 4, the degree of depth partly penetrating tank 4 is the half of saw bit matrix 2 thickness; Here spaced apart refers to; On upper sagittal plane every two and half penetrate just to be provided with between tank one be positioned at lower sagittal plane partly penetrate tank; On lower sagittal plane every two and half penetrate just to be provided with between tank one be positioned at sagittal plane partly penetrate tank; Be provided with cutter head 5 at every two adjacent sawtooth formed between tank 4 that partly penetrate, all cutter heads 5 form a circle; Namely on the upper sagittal plane and lower sagittal plane of whole matrix, a circle cutter head is all provided with.
The degree of depth partly penetrating tank be from saw bit matrix facing radially towards lower or little facing radially towards on to the position of matrix thickness half.
The design (as shown in A in Fig. 4) that existing saw bit matrix is penetrated tank by the utility model changes interval, both sides into and partly penetrates tank, in use, the both sides sawtooth of saw bit matrix 4 welds cutter head 3.
The utility model cutting process as shown in Figure 1, workpiece to be machined 7 enters cutting region at cut process cutter head 5, start stable cutting, be about to enter cutting process cutter head 6 and also start incision at subsequent time, be about to enter in cutting process cutter head 6 cut process, cutting process cutter head 5 provides side supplemental support for it, increases the stability of incision.And because cutter head is alternately welded on cylindrical both sides, the thickness of incision cutter head reduces by half, and further reduces the impact in cut process.
Tank 4 plays chip removal effect in saw kerf in the process.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
