Description
Technical field
The present invention relates to a kind of wood cutter, particularly carbide alloy wood cutter.
Background technology
Along with the raising of people's living standard, also there are continuous renewal, higher requirement to the quality of furniture.But a conventional class can make the counterbore cutter also doing groove milling and deburring in the timber processing at present on domestic, 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 the demand of domestic, international market is in progressively ascendant trend, and grow a lot space.The key of clear bed plate tool is its cutter head portion, the carbide chip at common straight knife cutter head place has segment distance in the radial direction in cutter heart portion, clear bed plate is in order to reach application target, the carbide chip at cutter head place must cross the sub-fraction heart in heart portion radial direction, could process smooth by counterbore base like this.As shown in Fig. 1-4, current clear bed plate is by together with high frequency, soldering processing by two panels carbide chip and matrix, normally output two skewed slots in the cutter head portion of matrix, wedge shape carbide chip is arranged in skewed slot, because the carbide chip radial direction at cutter head place will be cared, so two skewed slot projections are in the vertical direction connected, in a line, add and also need to offer chip area, make the matrix thickness at knife head place very thin, thermal capacity is very little.Because knife head matrix thickness is too thin, when welding, matrix temperature distortion is very large, carbide chip is easy to fracture, even if weld the carbide chip into no fracture, when postorder sharpening because thermal stress adds that grinding force waits until that external force is accumulated, also have the fracture of part generation carbide chip.After finished product, in use, because of carbide chip residual stress, and the reason such as matrix head strength difference, knife particularly head overall fracture soon or gross distortion may be caused, or 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 improvement of cutter head construction, strengthen intensity and the thermal capacity of matrix head, the thermal stress deformation of matrix head after 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, and matrix head has two symmetrical skewed slots, two skewed slot projection A in a distance in the vertical direction; The hypotenuse of the large end of wedge shape carbide chip has projection, and the height of projection is equal to or greater than A/2; Wedge shape carbide chip is by hypotenuse and projection base location and installation in matrix skewed slot, and soldering is fixed on matrix.
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, distance A value is 1.0mm.
Preferably, during clear bed plate diameter Ф 6.4mm < X≤Ф 12.7mm, distance A value is 1.5mm.
Preferably, during clear bed plate diameter Ф 12.7mm < X≤Ф 19.1mm, distance A value is 1.8mm.
Preferably, during clear bed plate diameter Ф 19.1mm < X≤Ф 25.4mm, distance A value is 2.0mm.
Preferably, during clear bed plate diameter Ф 25.4mm < X≤Ф 31.8mm, distance A value is 2.5mm.
Preferably, during clear bed plate diameter Ф 31.8mm < X≤Ф 38.1mm, distance A value is 3.0mm.
Preferably, during clear bed plate diameter Ф 38.1mm < X≤Ф 50.8mm, distance A value is 3.5mm.
Invention enhances intensity and the thermal capacity of matrix head, the thermal stress deformation of matrix head after high-frequency welding can be reduced, avoid cutter head place to rupture and the problem such as fracture of carbide chip, improve product percent of pass and the service life of the production of clear bed plate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Fig. 5-8, the reinforced clear bed plate of the present invention, matrix 1 head has symmetrical two skewed slots, 3, two skewed slot 3 projection in the vertical direction A in a distance; The hypotenuse 4 that wedge shape carbide chip 2 is held greatly has projection 5, and the height H of projection 5 is equal to or greater than A/2; Wedge shape carbide chip 2 passes through the base location and installation of hypotenuse 4 and projection 5 in matrix skewed slot 3, and soldering is fixed on matrix.After having welded, the radial blade of carbide chip end crosses matrix axle center completely, instructions for use can be met, and the thickness of matrix end improves greatly, thus improve intensity and thermal capacity, the thermal stress deformation of high-frequency welding can be reduced, avoid the fracture of the fracture of cutter head place and carbide chip, meanwhile, cutting-tool's used life can also be improved well.
Further, wedge shape carbide chip hypotenuse 4 has transition arc with the junction on projection 5 base, 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 A value is larger, the width of carbide chip is less, and the intensity of carbide chip is 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 distance A value is directly proportional to sword footpath.
Preferably, during clear bed plate diameter X≤Ф 6.4mm, distance A value is 1.0mm.
Preferably, during clear bed plate diameter Ф 6.4mm < X≤Ф 12.7mm, distance A value is 1.5mm.
Preferably, during clear bed plate diameter Ф 12.7mm < X≤Ф 19.1mm, distance A value is 1.8mm.
Preferably, during clear bed plate diameter Ф 19.1mm < X≤Ф 25.4mm, distance A value is 2.0mm.
Preferably, during clear bed plate diameter Ф 25.4mm < X≤Ф 31.8mm, distance A value is 2.5mm.
Preferably, during clear bed plate diameter Ф 31.8mm < X≤Ф 38.1mm, distance A value is 3.0mm.
Preferably, during clear bed plate diameter Ф 38.1mm < X≤Ф 50.8mm, distance A value is 3.5mm.
After adopting structure of the present invention and parameter thereof, use through reality, after welding, carbide chip leafing rate reduces to 0 by 20%, during sharpening, carbide chip leafing rate reduces to 0 by 10%, during use, the overall fracture rate in cutter head place reduces to 0 by 90%, substantially increase product percent of pass and service life, have good economic benefit.
Obviously, above embodiment is only citing made for the present invention, and the restriction not 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 exhaustive without the need to also giving all embodiments.And these belong to spirit institute's apparent change of amplifying out of the present invention or change and are still among protection scope of the present invention.
