Description
Technical field
The present invention relates to a kind of tabular cutting tools and a kind of stationary fixture; In tabular cutting tools; Be soldered to as the length direction ora terminalis of the pedestal of rectangular plate shape base part as the cutting tip of blade part and partly go up forming cutting edge, this stationary fixture is located also fixed pedestal and cutting tip when set pedestal and cutting tip securely.
Background technology
In Wood Processing or similar processing, use thicknessing and planning machine to make having an even surface of member to be cut; In this thicknessing and planning machine; Rotatably settle the cylindrical cutting element that is known as planer head, and utilize the planing tool of being located on the planer head outer surface to cut board member or similar component.The traditional planing tool that in this flush cut, uses is the planing tool described in patent documentation 1; For example; Length direction two ora terminalis of carbide alloy or analog partly are formed rectangular plate shape, and polished on length direction two ora terminalis part, to form cutting edge.Generally speaking, about four planing tools are installed on the planer head, and the cutting edge of each planing tool is outstanding slightly from the outer surface of planer head.Planing tool shown in the prior art alongst is formed on two length direction ora terminalis parts the blade part; Therefore the cutting edge of a blade part in this blade part since the use in flush cut become can not the time spent, planing tool is installed the use of guaranteeing another blade cutting edge partly in the opposite direction.And, when the cutting edge of another blade part also becomes can not the time spent, replacement planing tool itself, and abandon the planing tool of using.
Patent documentation 1: real fair 2-23371 number of Japan.
Planing tool shown in the prior art is designed to, when the cutting edge of both sides all becomes can not the time spent, must the whole planing tool of replacement.But the carbide alloy that forms planing tool is more expensive than materials such as steel; And; It is less that blade partly accounts for the ratio of whole cutting element, therefore, and owing to the wearing and tearing of blade part are replaced the whole planing tool that carbide alloy processes and will be caused the business efficiency of difference and increase operating cost.
In view of this point, can form by steel cheaply as the pedestal of the major part of planing tool, but as the cutting tip split of blade carbide alloy partly be welded on the pedestal, thereby reduce the manufacturing cost of whole planing tool.But when pedestal and cutting tip were formed by different materials, the thermal coefficient of expansion of two kinds of members just differed from one another naturally, when welding and cooling, can between two kinds of deformation of members amounts, produce difference.That is, because usually steel has the thermal coefficient of expansion higher than carbide alloy, therefore when heating and cooling, steel has than the relative bigger expansion of carbide alloy and changes, therefore can residual big internal stress on planing tool after the welding.Residual stress cause following problem: the strain that can not revise on whole planing tool, occurs or on cutting tip, produce the crack.Therefore, so far, do not provide as yet through being welded to the practical planing tool of making on the pedestal that forms by steel by the cutting tip that the sintered hard material forms.Though through carrying out soldering and cutting tip be attached on the pedestal being lower than under the temperature of welding, the strain and the crack that occur in the time of suppressing the above-mentioned cutting tip of combination, this way only limits to sectional area very greatly to guarantee the cutting tip of soldering area basically.This be because, combine with inadequate soldering area to cause not enough bond strength, cause cutting tip can not bear use as cutting element.Therefore, there are the cutting elements such as planing tool of the long-pending wire cutting tip of small bore not put in the practical application as yet such as soldering.
In design process of the present invention, the present inventor has carried out the correlation between the sectional area of crack/strain that following experiment confirms when the cutting tip that the sintered hard material is formed is welded on the pedestal that is formed by steel, may to occur and cutting tip.

Obtain the chart shown in Figure 12 (a) and Figure 12 (b) from measurement result.The number in the crack that the histogram graph representation shown in Figure 12 (a) is produced on cutting tip 70 corresponding to each cutting tip sectional area S.Obvious from chart, be 2.55mm at cutting tip sectional area S
2To 5.1mm
2Situation under, do not produce the crack, and be 5.95mm at cutting tip sectional area S
2Or under the bigger situation, the number in the crack that is produced increases according to the size of cutting tip sectional area S.Relation between the dependent variable δ of each cutting tip sectional area S of the graphical presentation shown in Figure 12 (b) and length direction ora terminalis part.Obvious from chart, along with diminishing of cutting tip sectional area S, the dependent variable δ of length direction ora terminalis part significantly increases.That is, the deducibility dependent variable δ and the cutting tip sectional area S that go out length direction ora terminalis part is inversely proportional to.
Afterwards, cutting tip 70 is being set as the length with 100mm, the width of 3.0mm and thickness (the cutting tip sectional area S=5.1mm of 1.7mm
2) and when pedestal 72 was set as the thickness of length with 100mm, 5 to 30mm width and 1.5mm, the inventor had carried out this experiment under the situation that changes pedestal 72 width.As a result, do not find the crack to occur on the cutting tip 70 and only found the strain of length direction ora terminalis part.
According to experimental result, the inventor thinks, if the cutting tip sectional area S of cutting tip 70 is about 5.0mm
2, can under the situation that does not produce the crack on the cutting tip 70, carry out laser weld so.Understanding according to following is made the present invention: strain (the particularly strain of length direction ora terminalis part) is along with diminishing of cutting tip sectional area S increases; If can successfully suppress strain; So the use of expensive sintered hard material can reduce significantly, can be applied to fully such as on the tabular cutting tools such as planing tool.
