Description

Fine-engraving milling micro-texture cutter for Dongfei ebony

Technical Field

The utility model relates to a finishing impression mills little texture cutter for east africa ebony.

Background

The Dongfei yellow ebony belongs to rosewood of tamarind branches, the air-dried density of the rosewood is 1.25-1.33g/cm3, the water content is 12%, the hardness of a simple card is 4050 pounds, the compressive strength along grain is 74.7Mpa, the bending strength is 266.5Mpa, and the bending elastic modulus is 20.59Gpa, and belongs to superhard wood.

The wood is widely applied to finished products of mahogany furniture, artware, commercial gifts and the like. According to statistics, the entrance amount of the rosewood in China is 14.45 ten thousand cubic meters in 2000, and is dramatically increased to 205.5 ten thousand cubic meters in 2014; as of 2016, more than 3 million mahogany furniture enterprises in China have an annual output value of over 1650 billion. The rosewood products are strongly loved by consumers at home and abroad, and the market is huge. Milling is an extremely important step in the processing process of the east African yellow sandalwood.

However, in the milling process, the characteristics of high strength, high hardness, wear resistance, anisotropy and the like of the east African yellow sandalwood cause large friction force and unstable milling force in the processing process, and the service life of the milling cutter is obviously reduced compared with other raw wood materials processed. According to the data provided by Sunday Red (Fujian) furniture Co.Ltd, the average life of the flat bottom sharp knife for processing Dongfei yellow sandalwood is only about 6 h. The cutter has a short service life, and frequent cutter changing is needed in the machining process, so that the machining efficiency is seriously influenced, the machining error is increased, and the economic benefit of an enterprise is greatly influenced.

Disclosure of Invention

In view of this, the utility model aims at providing a finishing impression mills little texture cutter for east non ebony, simple structure, easy and simple to handle can increase the heat radiating area of knife face.

The technical scheme of the utility model is that: the utility model provides a finishing impression mills little texture cutter for east is black yellow sandalwood, includes the handle of a knife, is provided with the blade at the handle of a knife front end, and it has three chip groove to distribute along blade center axis array on the blade, the blade includes cylinder portion and circular cone portion, is provided with the cutting edge at the position that chip groove and toper portion meet, is provided with little texture stripe near the front end of cutting edge one side in the chip groove, is provided with the edge on the toper portion.

Furthermore, the included angle between the edge and the central axis of the knife body is 20 degrees.

Further, the chip groove comprises a groove bottom, a groove surface A and a groove surface B.

Further, the flute surface a is close to the blade edge and the flute surface a is a plane.

Further, the groove surface B is an arc surface.

Further, the diameter of the knife handle is larger than that of the knife body.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has the advantages of being simple in structure and easy and simple to handle, can increase the heat radiating area of knife face, the saw-dust of can also in time discharging reduces cutter wearing and tearing, increases cutter life.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

As shown in fig. 1-4, a micro-texture cutter for fine carving and milling of Dongfei yellow sandalwood comprises a cutter handle, wherein a cutter body is arranged at the front end of the cutter handle, three chip removal grooves are distributed on the cutter body along a central axis array of the cutter body, the cutter body comprises a cylindrical part and a conical part, a cutting edge is arranged at the part where the chip removal grooves are connected with a conical part, a micro-texture stripe is arranged at the front end of one side, close to the cutting edge, in each chip removal groove, and an edge is arranged on the conical part. The chip discharge groove can discharge the cut sawdust in time, and the sawdust is prevented from being clamped between the conical part and the cutting surface of the Dongfei ebony, so that friction heating is easily caused. The front end of one side, close to the cutting edge, in the chip groove is provided with the micro-texture stripe, so that the stress concentration of the cutter tip is reduced, the blade breakage is avoided, and the service life of the cutter can be prolonged. The cutting edge is arranged at the connecting part of the chip groove and the conical part, so that the cut sawdust can be discharged into the chip groove in time. The arrangement of the edge can reduce the contact area between the peripheral surface of the conical part and the Dongfei black wingceltis wood, and further increase the heat dissipation area between the conical part and the Dongfei black wingceltis wood. The micro-texture fringes are fringe textures with certain sizes and distribution, a femtosecond laser is adopted to carry out fringe processing on the surface of the cutter, and the cross section size is as follows: depth 10 μm, width 25 μm, and pitch 50 μm; is arranged at the front end of the conical part, is close to the cutting edge and is arranged in parallel, and is 5mm away from the cutter point.

In this embodiment, the included angle between the edge and the central axis of the blade body is 20 °.

In this embodiment, the flute includes a flute bottom, a flute face a and a flute face B.

In this embodiment, the flute surface a is close to the blade edge, and the flute surface a is a plane.

In this embodiment, the groove surface B is an arc surface. The arc-shaped surface is beneficial to improving the chip removal efficiency.

In this embodiment, the diameter of handle of a knife is greater than the diameter of blade.

The specific implementation mode is as follows: during operation, the cutter handle of the cutter is clamped on the milling machine, the milling machine is started, the cutter rotates around the central shaft, the Dongfennei ebony is milled, the cutting edge continuously mills the Dongfennei ebony in the milling process, and sawdust generated by cutting is discharged from the chip discharge groove.

Above-mentioned operation flow and software and hardware configuration only do as the preferred embodiment of the utility model discloses a not therefore restrict the patent scope of the utility model, all utilize the utility model discloses the equivalent transform of doing of description and attached drawing content, or directly or indirectly use in relevant technical field, all the same reason is included in the patent protection scope of the utility model.
