Abstract
The utility model relates to a cutter of a handheld electric planer for wood working, in particular to a universal quick-change double-edge plane cutter. The plane cutter comprises a long strip-shaped positioning groove which is arranged at the center of the plane cutter, wherein two sides of the long strip-shaped positioning groove are respectively provided with a quick-change double-edge plane cutter body with a single-back angle cutting edge, and the single-back angle cutting edge is provided with a new back cutter surface to form a double-back angle structure. The angle error between the back angle and a adjoining back angle of the new back cutter surface is from 2 degrees to 5 degrees, the width of the new back cutter surface is from 0.2mm to 0.7mm, and the surface roughness Ra of the new back cutter surface is from 0.2 to 0.4. The novel quick-change double-edge plane cutter with the technical scheme is simple in structure, durable, and higher in the sharpness of the cutting edges and the intensity of the point of the cutter.
Description
Technical field
The utility model relates to a kind of cutter of hand-held electric planer for wood working, relates in particular to a kind of general quick-changing type twolip planing tool.
Background technology
Woodworking plane edge particularly hand electric planing tool is widely used in the processing of furniture and woodenware product, and it has significantly improved the plane working (machining) efficiency, has alleviated labor strength.The hand electric planing tool is to rotate on the cutter shaft that is being equiped with some planing tools under the drive of high-speed electric expreess locomotive, workpiece is carried out the planing operation of plane surface.General quick-changing type twolip planing tool is a kind of cutter the most frequently used on the electronic planing tool of carpenter, and it not only needs sharp cutting edge, so that it possesses good cutting ability; Simultaneously also need to possess point of a knife intensity preferably, increase the service life simultaneously so that cutter satisfies different environments for use.Existing quick-changing type twolip planing tool only is provided with a back angle owing to be subjected to the restriction of shape and size.In this case in order further to improve the sharpness of planing tool cutting edge, traditional solution has two kinds: the one, by increasing the planing tool relief angle, reducing nose angle realizes, but weakened point of a knife intensity like this, seriously reduce the service life of cutter, also can influence the installation location benchmark of planing tool simultaneously; The 2nd, improve the sharpness of cutting edge by the surface roughness of knife face behind the raising planing tool, but, reduced the competitiveness of product in market like this with regard to increasing the manufacturing cost of product greatly.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple structure, and is permanent durable, the novel quick-changing type twolip planing tool that has not only had higher cutting edge sharpness but also had higher point of a knife intensity.
In order to solve the problems of the technologies described above, a kind of novel quick-changing type twolip planing tool of the utility model, include middle position and be provided with a strip locating slot, both sides are respectively arranged with the quick-changing type twolip planing tool cutter hub of a single relief angle cutting edge, described single relief angle cutting edge is provided with a new back knife face, forms two backs corner structure.The new formed new relief angle of back knife face and the differential seat angle of adjacent relief angle are 2 °～5 °, and the width of new back knife face is 0.2mm～0.7mm, and the surface roughness Ra of new back knife face is 0.2～0.4.
Adopt the novel quick-changing type twolip planing tool of technique scheme,, make point of a knife intensity obviously increase much the service life of having improved planing tool greatly than the product of single relief angle owing to adopted the structure of two relief angles; Because the differential seat angle between adjacent two relief angles is smaller, and the back knife face that increases newly has very high surface roughness (the Ra value of the surface roughness of conventional blades is about 0.8), thereby improved the sharpness of planing tool cutting edge greatly, improved the cutting ability of planing tool; Because the width of the new back knife face that increases is between 0.2mm-0.7mm, such width has not only been protected the original installation of planing tool location benchmark, makes the manufacturing cost of product not have big variation simultaneously, makes it have more the market competitiveness.
Description of drawings
Fig. 1 is the front view of the utility model embodiment 1;
Fig. 2 be the utility model embodiment 1 A-A to the cross section enlarged drawing.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Embodiment 1
As depicted in figs. 1 and 2, the utility model provides a kind of novel quick-changing type twolip planing tool, include middle position and be provided with a strip locating slot 4, both sides are respectively arranged with the quick-changing type twolip planing tool cutter hub 3 of a single relief angle cutting edge 2, described single relief angle cutting edge 2 is provided with a new back knife face 1, forms two backs corner structure.The new back knife face 1 formed new relief angle and the differential seat angle of adjacent relief angle are 5 °, and the width of new back knife face 1 is 0.7mm, and the surface roughness Ra of new back knife face is 0.4.
Embodiment 2
The structure of quick-changing type twolip planing tool is with embodiment 1, and difference is that the differential seat angle of new back knife face 1 formed new relief angle and adjacent relief angle is 2 °, and the width of new back knife face is 0.2mm, and the surface roughness Ra of new back knife face is 0.2.
Embodiment 3
The structure of quick-changing type twolip planing tool is with embodiment 1, and difference is that the differential seat angle of new back knife face 1 formed new relief angle and adjacent relief angle is 4 °, and the width of new back knife face is 0.5mm, and the surface roughness Ra of new back knife face is 0.3.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
