Detailed Description

In order to more clearly illustrate the embodiments of the present invention and/or the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort. In addition, the term "orientation" merely indicates a relative positional relationship between the respective members, not an absolute positional relationship.

Please refer to fig. 1. The invention relates to a spiral bamboo wood hobbing cutter, which comprises: the bamboo wood cutting tool comprises a tool body 1, spiral blade teeth 2 distributed along the radial direction of the tool body 1 and a spiral blade 3 fixedly connected to the spiral blade teeth 2, wherein a chip cutting groove 4 is formed in the spiral blade 3 and used for enabling the chip cutting groove 4 to cut bamboo wood spirally when the tool body 1 rotates.

This application cutter can adopt the round steel to process into the spiral cutter body for raw and other materials, and spiral blade 3 can weld on spiral blade tooth 2 with metal material (like carbide, polycrystalline diamond, ceramic blade, high-speed steel blade etc.) to this hardness and the intensity that increases the blade, make more durable when in-service use.

It should be noted that, the reason why the inventor considers that the spiral blade teeth 2 are arranged in a spiral shape is that many problems occur in the conventional hobbing straight knife: firstly, in the hobbing processing, because the high-speed cutting between cutting edge and the bamboo timber, must produce a large amount of heats, when the condition such as bamboo timber feeding temporary stop, the heat that the cutting produced can produce the burn mark on cutting edge cutting surface, influences the follow-up result of use and the life-span of cutting edge, increases cutter passivation speed, and the inhomogeneous temperature distribution of cutter body still can make the cutter lose stability. Meanwhile, part of the bamboo materials may be due to the problem of materials, if water columns are sprayed to cool the cutting edges during processing, a large amount of cooling water is sprayed on the bamboo materials to influence the quality of the bamboo material of the follow-up processed products, and when the temperature of the cutting edges is too high due to poor heat dissipation effect of the cutting edges, scorching traces may be left on the bamboo materials. And the helical blade tooth 2 of this application can the cutting of branch point, has reduced the area of contact with the bamboo timber in the unit interval, and then the radiating effect can be better, and stability is stronger. Secondly, the material of part bamboo timber is probably harder, when using the straight sword to cut the bamboo timber, because the unit lifting surface area in the unit time is big, the resistance that forms is also big, very easily form the cutting deformation, the cutting face can't reach smooth even effect, perhaps tear the bamboo timber surface even, the bamboo timber after cutting like this can't satisfy the requirement of follow-up processing, the waste of resource and manpower has been caused, the price at the bamboo timber is higher and higher, the processing cost is more and more high at present, the economic loss who causes like this is also huge. Meanwhile, the straight cutter cuts bamboo materials due to a plurality of points simultaneously, reverse resistance to the cutter in unit time is several times of resistance generated when the spiral blade teeth 2 are processed, so that in long-term use, a plurality of bamboo waste products can be easily generated, the cutter is easily damaged under the reaction of large resistance for a long time, and the processing efficiency of a cutting surface can be influenced if the bamboo waste products are not found in time. And the spiral setting of the spiral blade teeth 2 of the present application makes the resistance to the cutter generated in unit time effectively reduced, and the spiral cutting can effectively disperse the resistance to a plurality of points of the spiral blade 3, rather than the stress point is fixed as in the case of a straight cutter, so that the spiral blade is more durable, and the spiral blade 3 can change the cutting point by adjusting the position of the cutter on the equipment, so that the service life of the cutter can be further increased. Third, the bamboo chips generated by the straight knife cutting are large, and the accumulated bamboo chips cannot be removed well in long-term work, which affects the processing quality. And the bamboo bits that the cutting of the helical blade 3 of this application produced are comparatively tiny, are changeed and get rid of.

The chip groove 4 of the present invention may be provided with 1 to 20 grooves, preferably 6 grooves in this embodiment, and the helical blade teeth 2 may be provided with 6 to 24 saw teeth at equal intervals, preferably 10 teeth in this embodiment, for processing different bamboo materials.

In a preferred embodiment, the cutter body 1 is further provided with a mounting hole 5. The mounting hole 5 is arranged at the radial center of the cutter body 1 in a penetrating manner, so that the cutter body 1 can be mounted on equipment for rotating the cutter body 1.

In a preferred embodiment, the mounting hole 5 is provided with a thread. The spiral can make the firm installation of cutter body 1 on making cutter body 1 pivoted equipment, can not drop from equipment in the course of the processing work.

In a preferred embodiment, a chip discharge groove 6 is also arranged between every two adjacent spiral blade teeth 2. The bamboo chips generated in the machining process can slide into the chip discharge grooves 6 along the sliding direction, so that the machining quality cannot be influenced due to the fact that the bamboo chips are accumulated near the spiral blade 3, and when the bamboo chips do not work, the chip discharge grooves 6 formed in the curved surface can also facilitate cleaning of the bamboo chips by workers.

As a preferred embodiment, the chip flutes 4 are equally spaced on the helical blade 3. Therefore, the bamboo material of the cutting chips can not be uneven in shape, and the production management is convenient.

As a preferred embodiment, the spacing between adjacent chip flutes 4 is 0.2-3 mm. The part of the helical blade 3 between the adjacent chip flutes 4 is the part which mainly cuts the bamboo material, and the part is not suitable to be too wide.

As a preferred embodiment, the axial width of the cutter body 1 is 10-100 mm.

As a preferred embodiment, the rake angle of the helical blade 3 is 1 to 50 degrees. As will be readily appreciated by those skilled in the art, the rake angle refers to the angle at which the front face of the helical blade 3 contacts the processed bamboo.

As a preferred embodiment, the screw blade 3 has a rear angle of 5 to 30 degrees. As will be readily appreciated by those skilled in the art, the relief angle refers to the angle at which the rear face of the helical blade 3 comes into contact with the helical blade teeth 2.

As a preferred embodiment, the helix angle of the helical blade 3 is 1-89 degrees. As will be readily appreciated by those skilled in the art, the helix angle refers to the helix angle of the helical blade.

As a preferred embodiment, the number of equally distributed sawteeth on the spiral blade teeth is 6-24.

For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
