Description
Technical Field
The utility model mainly relates to the field of milling tools, in particular to a novel wood cutting tool.
Background
When wood cutting is carried out, the hardness of the cutter is far higher than that of wood and modern artificial wood materials, the structural resistance of the wood and the bonding force of glue are overcome, the material on the surface layer of a workpiece is subjected to large elastic and plastic deformation, meanwhile, the cutter is correspondingly abraded by the reaction force of the workpiece, and a plurality of complex mechanical, physical and chemical phenomena and the like are generated in the wood cutting process. The novel wood cutting tool disclosed by the utility model is most labor-saving by adopting a rotary cutting mode according to the characteristics of forest cutting, so that high-power cutting can be completed by low-power, and the novel wood cutting tool has the advantages of high branch cutting speed, high productivity and smooth section.
Disclosure of Invention
The utility model mainly aims to design a novel wood cutting tool, so that a pruning machine is most labor-saving in cutting, can realize low-power completion of high-power cutting, and has the advantages of high branch cutting speed, high productivity and smooth section.
In order to achieve the above object, there is provided according to the present invention a novel wood cutting tool, comprising: the cutter comprises a cutter handle and a cutting edge, wherein the cutter handle is positioned at two ends of the cutter and is cylindrical, a fastening groove is formed in the middle of the cutter handle, a flat key groove is longitudinally formed in the outer side surface of the cutter handle, and the fastening groove and the flat key groove are used for circumferentially and axially fixing the cutter when the cutter is connected with a coupling; the cutting edges are arc-shaped cutting edges with two teeth, and the material design of the cutting edges adopts high-speed steel.
Furthermore, the fastening grooves are conical and are symmetrically distributed on the tool handles at two ends of the tool; the length of the flat key groove is 2/3 of the length of the knife handle, and the flat key groove is symmetrically distributed on the knife handles at two ends of the knife.
Further, the length of the double-tooth working part of the cutter is 60mm, and the diameter of the cutter is 10 mm.
Furthermore, the number of teeth of the cutter is double, the section of the tooth groove of the cutter is arc-shaped, the center width is designed to be 2.6mm for ensuring the strength of the milling cutter, and the center width is gradually increased from the end part to the tail part of the milling cutter.
Further, the tooth grooves of the cutter are straight groove teeth, the cutting angle of the end blade of the cutter is 90 degrees, the cutter is cut into brittle materials and is cut intermittently when wood is cut, and the rake angle of the cutter with the cutting edge is designed to be 12 degrees.
Furthermore, the back of the cutter tooth is in a narrow-edge structure, the back angle of the narrow edge is 10 degrees, the back angle of the back of the tooth after the narrow edge is 45 degrees, and the motion back angle is larger because the contact area of the narrow edge and the cutting surface is small.
The utility model has the beneficial effects that: the utility model provides a characteristic when the novel wood cutting tool, when cutting according to the forest, adopts the rotary cutting mode laborsaving most, through the design to the cutter cutting parameter, can realize that miniwatt power accomplishes high-power cutting, has that higher cutting branch is fast, productivity ratio is high, the tangent plane is smooth.
Drawings
Figure 1 shows a schematic view of a new wood cutting tool.
Figure 2 shows a schematic cross-sectional view of a novel wood cutting edge.
In the figure: 1-cutting edge, 2-fastening groove, 3-flat key groove and 4-knife handle.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the utility model and not as limiting the scope of the utility model. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Examples
Referring to fig. 1, a novel wood cutting tool includes: the cutter comprises a cutter handle 4 and cutting edges 1, wherein the cutter handle 4 is positioned at two ends of a cutter, a fastening groove 2 is formed in the middle of the cutter handle 4, a flat key groove 3 which is longitudinally formed is formed in the outer side surface of the cutter handle 4, and when the cutter is connected with a coupler, the fastening groove 2 and the flat key groove 3 fix the cutter in the circumferential direction and the axial direction; the cutting edge 1 is a circular arc cutting edge with two teeth, and the material design of the cutting edge 1 adopts W18Cr4V high-speed steel. The fastening grooves 3 are conical and are symmetrically distributed on the tool handles 4 at the two ends of the tool; the length of the flat key groove 3 is 2/3 of the length of the knife handle 4, and the flat key groove is symmetrically distributed on the knife handles 4 at two ends of the cutter.
Referring to fig. 2, a cross-sectional view of a cutting edge 1 is shown, in order to improve cutting quality and productivity, the number of teeth of the cutter is designed to be double, the tooth space section of the cutter is designed to be circular arc, the center width is designed to be 2.6mm to ensure the strength of the milling cutter, and the center width is gradually increased from the end to the tail of the milling cutter. The tooth space of the designed cutter is a straight groove tooth, the cutting angle of an end edge of the cutter is 90 degrees, the cutter is a brittle material and is cut intermittently when wood is cut and processed, and the front angle of the cutter with a designed cutting edge is 12 degrees. In order to solve the contradiction between the diameter of the cutter and the width of the mortise, the tooth back of the cutter is designed to be in a narrow edge structure, the back angle of the narrow edge is 10 degrees, the back angle of the tooth back part behind the narrow edge is 45 degrees, and the motion back angle is larger because the contact area between the narrow edge and the cutting surface is small.
