The invention can quench the all working part of the tooth, so the root of the tooth is protected, the laser intensifying has the inhere advantage of intensifying, so the saw piece has many merits such as the long using life, the better ability of standing up the tear, the fixedness and the without the crack.
Description
Technical field
The present invention relates to laser reinforcing and metallic substance thermal treatment field, particularly a kind of laser-quenching technique method that is applied to circular saw bit.
Background technology
Diameter is a Φ 1500-2200mm circular saw bit at present, has been widely used in the online high-speed cutting steel of iron and steel enterprise, and the wearing and tearing when cutting for enabling to bear need carry out quenching strengthening to tooth portion.Present similar circular saw bit enhancement method has high-frequency quenching and process furnace to quench.
The high-frequency quenching saw blade wears no resistance, and the distortion of process furnace quenching saw blade is big, and especially they all inevitably will be quenched to tooth root, cause stress concentration, are easy to generate crackle in use, and are totally unfavorable to the saw blade safety of high-speed cutting.
Also useful in the past laser is to the example of circular saw bit quenching strengthening, but laser beam shines from the side, be that machine tool chief axis is parallel with the light beam irradiates direction, quenched in the both sides of saw blade teeth, quench less than fire in the teeth middle part, do not make the working position of whole teeth obtain quenching, so the inhomogeneous unanimity of teeth intensity, collapse tooth easily.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of laser reinforcing technological method that is used for circular saw bit, the working position of its whole teeth can both be strengthened, and saw blade is more durable.
The object of the present invention is achieved like this: a kind of laser reinforcing technological method that is used for circular saw bit is characterized in that comprising following sequential steps: (1) is installed in circular saw bit on the machine tool chief axis; (2) adopt extinction coating that tooth portion is applied pre-treatment; (3) tooth portion is carried out laser reinforcing and handle, machine tool chief axis is vertical with the light beam irradiates direction, and light beam radially shines circular saw bit.
In the described step (1), saw blade is installed on the machine tool chief axis with the lathe main axis rotation, by locating device control saw blade swing degree≤1mm.
In the described step (3), the circular saw bit sense of rotation for make hot spot from crown to the tooth root scanning direction.
In the described step (3), the back of tooth of light beam irradiates circular saw bit.
In the described step (3), the sweep stopping point position is by realizing with being in the light of a back tooth crown.
In the described step (3), laser output power is 1800W～3600W, sweep velocity 700～900mm/min.
In the described step (3), laser apparatus adopts broadband integration camera lens, and spot width is than the big 2-4mm of saw blade thickness.
The working position that the present invention has whole teeth obtains quenching; the tooth root of teeth is protected; laser reinforcing institute inherent reinforcing edge in addition, the saw blade of strengthening with the present invention has long service life, wear resistance is better, indeformable, the advantage that is not easy to crack.
Description of drawings
Fig. 1 is a scheme of installation of the present invention;
Fig. 2 is a work synoptic diagram of the present invention.
Embodiment
The present invention is a kind of laser reinforcing technological method that is used for circular saw bit, mainly comprises following sequential steps, at first circular saw bit 2 is installed on the machine tool chief axis 1, adopts extinction coating that tooth portion is applied pre-treatment then; At last tooth portion is carried out laser reinforcing and handle, machine tool chief axis 1 is vertical with light beam 3 direction of illuminations, and saw blade 2 is installed on the machine tool chief axis 1 and rotates with lathe main shaft 1, and 3 pairs of circular saw bits 2 of light beam radially shine (as shown in Figure 1).Saw blade 2 is installed on the machine tool chief axis 1, preferably by locating device control saw blade swing degree≤1mm.For adapting to the saw blade of handling different diameter, can be by main shaft 1 height of center of lathe selective headstock being increased to greater than circular saw bit 2 radiuses with base, this saw blade installation method makes the present invention not be subjected to the influence of saw blade diameter.
Extinction coating is aggregate with the carbon element, can form protective atmosphere when laser radiation, avoids strengthening layer oxidation, decarburization, makes saw blade antifatigue more.Tooth portion is applied the extinction coating that crown 21 is removed in the back wiping, make crown 21 unlikely fusings, saw blade is in use sharper, and the cutting resistance is littler.
As shown in Figure 2, tooth portion is carried out in the laser reinforcing treatment step, circular saw bit 2 sense of rotation be make light beam 2 hot spot from crown 21 to the tooth root scanning direction, make the little crown position of thermal capacity have identical temperature rise with the big denticle of thermal capacity, make the unlikely burning in crown position; The back of tooth 23 of light beam 3 irradiation circular saw bits 2 makes the back of tooth 23 little molten reinforcements and the preceding flank of tooth 22 is phase transformation strengthening, makes the sticking tooth of laser saw blade; Can be in the light by the crown with a back tooth and realize in hot spot sweep stopping point position, be from tooth root 2mm to the sweep stopping point position of each tooth, can avoid tooth root to quench to fire; Laser output power will be decided according to selected DE Lens Flares width and flute profile size, and the best is 1800W～3600W, requires shadow surface (back side) little molten, and the non-shadow surface (front) of tooth is a canescence quenching vestige, sweep velocity 700～900mm/min; Laser apparatus adopts broadband integration camera lens, spot width is than the big 2-4mm of saw blade thickness, so that a saw blade can have been swept together, whether scanning process need be observed the light beam irradiates face little molten, whether non-shadow surface (front) is canescence quenching vestige, in time adjusts power and speed.The heating region of saw blade laser quenching is little, makes saw blade saw blade laser quenching distortion little.
Embodiment
To thickness is 16mm, and diameter is Φ 2100mm, and the circular saw bit of cutting H shaped steel carries out intensive treatment, and step is as follows:
(1) the saw blade deflection of marching into the arena detects;
(2) by shown in Figure 1 pending saw blade is installed on the machine tool chief axis, and degree of swing is adjusted to less than 1mm;
(3) adopt broadband integration camera lens, H=20mm;
(4) tooth portion is carried out blacking extinction coating, wipe crown coating then;
(5) hot spot radially shines circular saw bit, and the main axis rotation direction is counter clockwise direction (shown in Fig. 1 arrow), wherein angle lens α=45., power N=2900W, external circe speed V=800mm/min;
(7) procedure quality monitors, whether observe the light beam irradiates face little molten, and whether non-shadow surface (front) is canescence quenching vestige, in time adjusts power and speed.
Simultaneous test
Table 1 is to be 16mm to thickness, and diameter is the test-results of being done on the cutting H shaped steel circular saw bit of Φ 2100mm.
Table 1.
By test as can be known, when the saw blade material adopted 65Mn, 45Mn2V, the saw blade of being handled by laser-quenching technique of the present invention exceeded near 1 times than existing technology by the calculation of sawing amount work-ing life, and sticking tooth, and the bent deflection of wooden dipper obviously is better than existing technology less than 1mm.
