Abstract

The utility model relates to a comb-shaped anti-avulsion cutter tooth structure used for wood material and wood material processing. The utility model is characterized in that the edge of the cutter tooth is not in a line but in comb shape; a plurality of triangle cutting edges, with equal or non-equal tooth clearances, are arranged on the cutter tooth. Compared with the traditional cutter tooth structure, the utility model has the advantages that the utility model is applied to precut the workpieces such as solid woods, bamboo material and artificial plates, etc., and cuts off the interlocked grain of the wood material and the bamboo material; when machined by a planing blade, the cutter tooth participates in the cutting with part interphase edges rather than with the whole edge; the generated cutting chippings are section by section rather than on the whole milling width; therefore, the wood material or bamboo material is not damaged on the cutting plane, and the processing defects such as excavation cutting, etc. are prevented. Furthermore, the edge and a rotary axis line are in a certain angle and the cutter tooth cuts by angles; on the same milling condition, the milling radius of the utility model is greater; therefore, the corrugated depth of the surface of the processed workpieces is small, with smooth surface. The cutting resistance is small in the whole process. Furthermore, the milling depth can be increased on the same power of a motor.

Description

The anti-knife-tooth structure of tearing of comb teeth shape

Technical field

The utility model relates to a kind of timber and bamboo processing and tear knife-tooth structure with comb teeth shape is anti-, it belongs to timber and bamboo processing is used the cutting-tool engineering field.

Background technology

At present, the processing of timber and bamboo wood plane all is to adopt the plane planing tool, and manufacturing deficiencies such as fiber is rubbed with the hands, torn, cutout often appear in finished surface.Part producer is because of can't reaching crudy, and the change production technology promptly need not be planed and be carried out plane processing, and uses heavy contact calibrating machine instead.Contact calibrating machine no doubt can reach desired surface roughness, but tolerance is difficult to satisfy the thickness of workpiece, and the sander power consumption is very big, and the sand paper waste is serious, this only is the makeshift that solves surface roughness, can not fundamentally solve workpiece surface roughness and dimensional tolerance problem.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of any knife-tooth structure that carries out timber and bamboo wood milling in the revolution mode that can be applicable to---the anti-knife-tooth structure of tearing of comb teeth shape.Technical solution of the present utility model: its structure is that the cutting edge of cutter tooth is not a straight line, but is comb teeth shape, cutter tooth several triangle cutting edges that distribute.Advantage of the present utility model (comparing): be used for work pieces such as solid wood, bamboo wood, artificial board are cut in advance with traditional knife-tooth structure, on the milling depth direction, cut off the cross lamination of timber and bamboo wood, shear tool adds man-hour, cutter tooth is not participated in cutting with whole cutting edge, but the alternate cutting edge cutting of part, the smear metal that forms is not on whole milling width, but segmentation, so timber or bamboo wood just can not destroy below the cutting plane, prevent the appearance of manufacturing deficiencies such as cutout.

In addition, cutting edge and axis of rotation at an angle, cutter tooth is an angle milling, as shown in Figure 3, according to ripple degree of depth Y=250*V _z ²/ 2R, wherein, V _zBe the feed engagement of cutter, R is the milling radius.Under equal milling condition, the milling radius of this utility model is bigger, and therefore, the work piece external waviness degree of depth is little, surfacing.The cutting resistance of whole process is less, and under equal power of motor, can increase milling depth.

Description of drawings

Accompanying drawing 1 is an Application Example structural representation of the present utility model.

Accompanying drawing 2 is the blade relative position schematic diagrames that are applied on the transposition cutter hub.

Accompanying drawing 3 is schematic diagrames of the work piece external waviness degree of depth

Among the figure 1 is cutter tooth, the 2nd, and blade, the 3rd, cutter hub.

The specific embodiment

The contrast accompanying drawing, utilize special emery wheel that the cutting edge of cutter is processed into the broach shape, shown in Figure 1, the cutting edge of cutter tooth is not a straight line, but be comb teeth shape, the cutter tooth triangle cutting edge that several space widths equate (or cutter tooth distribute the unequal triangle cutting edge of several space widths) that distributes.Be used for work pieces such as solid wood, bamboo wood, artificial board are cut in advance, on the milling depth direction, cut off the cross lamination of timber and bamboo wood, shear tool adds man-hour, timber or bamboo wood just can not destroy below the cutting plane, prevent the appearance of manufacturing deficiencies such as cutout.And, cutting edge and axis of rotation at an angle, cutter tooth is an angle milling, the work piece external waviness degree of depth is little, surfacing.The cutting resistance of whole process is less, under equal power of motor, can increase milling depth.

As shown in Figure 2, staggering relatively between the blade in use, this figure 1/2 facewidth that staggers relatively makes shear tool add man-hour, the work piece surfacing.

As Fig. 3, ripple degree of depth Y=250*V _z ²/ 2R, wherein, V _zBe the feed engagement of cutter, R is a radius of clean-up.Under equal machining condition, the milling radius of this utility model is bigger, and the corresponding ripple degree of depth is just less, so the surface is comparatively smooth.

Claims

1, comb teeth shape is anti-tears knife-tooth structure, and it is characterized in that the cutting edge of cutter tooth is not a straight line, but be comb teeth shape, cutter tooth several triangle cutting edges that distribute, blade is located on leg-of-mutton two sides.
