Description
Technical field
The present invention relates to a kind of wood cutter, particularly the carbide alloy wood cutter.
Background technology
Along with the raising of people's living standard, the quality of furniture also there are continuous renewal, higher requirement.Yet a class commonly used can be made counterbore with the cutter that also can do groove milling and deburring in the at present processing of the timber on domestic, the international market---be exactly straight knife of the clear end.Clear bed plate has the advantages such as purposes is wide, the scope of application is large, quantity required is many, cost performance is high, easy to use, simple, and demand domestic, the international market is progressively ascendant trend, and the space grows a lot.The key of clear bed plate tool is its cutter head section, the carbide chip at common straight knife cutter head place upwards has segment distance in the footpath of cutter heart section, clear bed plate is in order to reach application target, the carbide chip at cutter head place directly upwards must be crossed the sub-fraction heart in heart section, and the processing of ability counterbore bottom is smooth like this.Shown in Fig. 1-4, present clear bed plate is that two carbide chips and matrix are in the same place by high frequency, soldering processing, normally the cutter head section at matrix leaves two skewed slots, the wedge carbide chip is installed in the skewed slot, because the carbide chip at cutter head place radially will care, so two skewed slot projections in the vertical direction link to each other, be a line, add also and need offer chip area that make the matrix thickness at knife head place very thin, thermal capacity is very little.Because knife head matrix thickness is too thin, the matrix temperature distortion is very large when welding, carbide chip is easy to fracture, even welding advances there be not the carbide chip of fracture, when the postorder sharpening, wait until the external force accumulation because thermal stress adds grinding force, also have the fracture of part generation carbide chip.Behind the finished product, in use, because of the carbide chip residual stress, reach the reasons such as matrix head intensity difference, may cause particularly soon whole fracture of head of knife, or gross distortion, or the carbide chip fracture.Therefore, the existing product structure working durability is short, and cost performance is low.
Summary of the invention
The present invention aims to provide a kind of reinforced clear bed plate, by the improvement of cutter head construction, strengthen intensity and the thermal capacity of matrix head, the thermal stress deformation of matrix head after the minimizing high-frequency welding, avoid the problems such as the fracture of cutter head place, carbide chip fracture, improve qualification rate and the service life of cutter.
Technical scheme of the present invention is: reinforced clear bed plate, matrix head have two symmetrical skewed slots, and two skewed slot projections in the vertical direction are at a distance of certain distance A; On the hypotenuse of the large end of wedge carbide chip projection is arranged, the height of projection is equal to or greater than A/2; In the matrix skewed slot, soldering is fixed on the matrix wedge carbide chip by hypotenuse and projection base location and installation.
Further, there is transition arc described carbide chip hypotenuse and junction, projection base.
Further, described distance A value is 1.0mm-3.5mm.
Preferably, during clear bed plate diameter X≤Ф 6.4mm, the distance A value is 1.0mm.
Preferably, during clear bed plate diameter Ф 6.4mm＜X≤Ф 12.7mm, the distance A value is 1.5mm.
Preferably, during clear bed plate diameter Ф 12.7mm＜X≤Ф 19.1mm, the distance A value is 1.8mm.
Preferably, during clear bed plate diameter Ф 19.1mm＜X≤Ф 25.4mm, the distance A value is 2.0mm.
Preferably, during clear bed plate diameter Ф 25.4mm＜X≤Ф 31.8mm, the distance A value is 2.5mm.
Preferably, during clear bed plate diameter Ф 31.8mm＜X≤Ф 38.1mm, the distance A value is 3.0mm.
Preferably, during clear bed plate diameter Ф 38.1mm＜X≤Ф 50.8mm, the distance A value is 3.5mm.
The present invention has strengthened intensity and the thermal capacity of matrix head, can reduce the thermal stress deformation of matrix head after the high-frequency welding, avoids the problems such as fracture of the fracture of cutter head place and carbide chip, improves product percent of pass and the service life of clear bed plate production.

Among the figure: 1-matrix, 2-carbide chip, 3-skewed slot, 4-hypotenuse, 5-projection.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 5-8, the reinforced clear bed plate of the present invention, matrix 1 head have symmetrical 3, two skewed slot 3 projections in the vertical direction of two skewed slots at a distance of certain distance A; On the hypotenuse 4 of wedge carbide chip 2 large ends projection 5 is arranged, the height H of projection 5 is equal to or greater than A/2; The base location and installation that wedge carbide chip 2 passes through hypotenuse 4 and projection 5 is in matrix skewed slot 3, and soldering is fixed on the matrix.After welding is finished, the radially blade of carbide chip end is crossed the matrix axle center fully, can satisfy instructions for use, and the thickness of matrix end improves greatly, thereby improved intensity and thermal capacity, can reduce the thermal stress deformation of high-frequency welding, avoided the fracture of the fracture of cutter head place and carbide chip, simultaneously, can also improve well cutting-tool's used life.
Further, wedge carbide chip hypotenuse 4 has transition arc with the junction on projection 5 bases, strengthens the bonding strength at projection place, avoids stress to concentrate.
Further, the projector distance A value of two the skewed slot vertical direction in matrix 1 end is larger, and the intensity of matrix head is better, and thermal capacity is larger, and the thermal deformation that welding causes is less; But the A value is larger, and the width of carbide chip is just less, and the intensity of carbide chip is just less.The optimum of overall balance is: the projector distance A value of two skewed slot vertical direction is taken as 1.0mm-3.5mm, and the distance A value directly is directly proportional with sword.
Preferably, during clear bed plate diameter X≤Ф 6.4mm, the distance A value is 1.0mm.
Preferably, during clear bed plate diameter Ф 6.4mm＜X≤Ф 12.7mm, the distance A value is 1.5mm.
Preferably, during clear bed plate diameter Ф 12.7mm＜X≤Ф 19.1mm, the distance A value is 1.8mm.
Preferably, during clear bed plate diameter Ф 19.1mm＜X≤Ф 25.4mm, the distance A value is 2.0mm.
Preferably, during clear bed plate diameter Ф 25.4mm＜X≤Ф 31.8mm, the distance A value is 2.5mm.
Preferably, during clear bed plate diameter Ф 31.8mm＜X≤Ф 38.1mm, the distance A value is 3.0mm.
Preferably, during clear bed plate diameter Ф 38.1mm＜X≤Ф 50.8mm, the distance A value is 3.5mm.
After adopting structure of the present invention and parameter thereof, use through reality, carbide chip leafing rate reduces to 0 by 20% after the welding, carbide chip leafing rate reduces to 0 by 10% during sharpening, the whole fracture rate in cutter head place reduces to 0 by 90% during use, greatly improved product percent of pass and service life, good economic benefit has been arranged.
Obviously, above embodiment only is to example of the present invention, and is not the restriction to embodiment of the present invention.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present invention amplified out and still are among protection scope of the present invention.
