Description

Mobius ring structure double-edge band saw

Technical Field

The utility model relates to a loop type saw technical field specifically is a Mobius loop configuration twolip band saw.

Background

The band saw is a metal strip with a toothed edge on the side, is made of a common alloy steel strip, achieves the purpose of sawing a workpiece by planing the workpiece with saw teeth and taking away saw dust through reciprocating motion, is widely applied to cutting frozen meat food, wood, plastic products, paper products, metal and other materials, and is widely applied to splitting, squaring, cutting, slicing and other applications. One improved generation is to connect the band saw end to form the annular endless band saw, and when in use, the annular band saw does continuous rotary motion along the same direction, and because the speed reduction, reversing and pause are avoided, the structure of the annular band saw machine is simplified and efficient cutting is easier to realize, so that the annular band saw machine which is smaller and more portable or large-size materials can be cut more efficiently.

Chinese invention patent CN106041771 and utility model patent CN205799280 disclose a superhard abrasive band saw. The superhard abrasive band saw comprises a base body formed by connecting a steel band head and a steel band tail into a ring shape, wherein the base body comprises a tooth-shaped part and a continuous tyre body part, a first accommodating space penetrating through the height of the tooth-shaped part is formed by extending a certain distance on the front surface of the tooth-shaped part along the thickness direction of the tooth-shaped part, a second accommodating space penetrating through the height of the tooth-shaped part is formed by extending a certain distance on the back surface of the tooth-shaped part along the thickness direction of the tooth-shaped part, and the extending distance of the first accommodating space in the thickness direction of the tooth-shaped part is equal to the extending distance of the second accommodating space in; and superhard abrasive layers containing superhard abrasive particles are arranged at the top ends of the first accommodating space, the second accommodating space and the tooth-shaped part. This patent describes in the specification that it has an annular band-like structure suitable for cutting high value materials.

Chinese utility model patent CN2400235 discloses a carpenter uses annular band saw blade, and its characterized in that band saw blade's both sides all are equipped with the tooth for large-scale ligneous cutting can improve wood-cutting machine's work efficiency. The Chinese patent CN104210038 discloses an annular diamond double-edge band saw and a manufacturing method thereof, wherein electro-deposition metal layers coated on edges on two sides of a stainless steel band are electroplated, diamond particles are uniformly solidified on the electroplated layers, and a diamond composite coating formed by the electro-deposition metal layers and the diamond particles is used for chip processing. The two inventions are characterized in that saw teeth or abrasive grains which play a role in sawing are arranged on two edges of the saw belt, but only one side edge actually participates in cutting during actual sawing, and the other side cannot effectively play a role in cutting because the other side cannot be reversed to a sawing position.

The Chinese invention patent CN102873401 discloses an annular superhard abrasive wire and a manufacturing method thereof, wherein the annular superhard abrasive wire comprises a wire rope with the diameter of 0.1-6 mm, superhard abrasive particles consolidated on the surface of the wire rope and a coating layer used for consolidating the superhard abrasive particles. The manufacturing method of the annular superhard abrasive wire is that the filament rope is firstly woven into an annular shape with any circumference, and then the superhard abrasive particles are solidified on the surface of the annular filament rope by a coating method, so that the annular superhard abrasive wire with high strength, uniform outer diameter and long service life is formed. The annular superhard abrasive wire saw is suitable for cutting conductor, semiconductor and non-conductor materials by using an annular wire cutting machine.

The chinese invention patent CN108381797 and the chinese utility model CN204136252 respectively disclose an annular diamond fret saw, which is structured by twisting and connecting metal base lines into an annular shape, and then arranging spiral or annular abrasive grain relief and chip grooves. This structure is difficult to consolidate larger particle abrasive particles due to the small surface area of the wire-bonded substrate and the limited total number of attachable abrasive particles is not sufficient for applications with large loads or high cutting efficiency.

International patent publication WO2014/063910 discloses a method of intermittently brazing abrasive grains to form serrations on the surface of a flat steel wire having a bonded mobius annular structure. US patent 4189968(1978-08-30, 1998-08-30 has expired) discloses a similar concept to the present invention, and proposes a method of manufacturing an improved band saw blade comprising providing a metal band of a predetermined length, both edges of which have cutting surfaces, and joining the butt ends of the band saw blade to form a mobius strip, which may have wooden, metal or plastic cutting teeth, a saw blade for cutting paper products, a bonded abrasive grain saw blade for cutting hard materials such as metal or ceramics, etc.

Japanese utility model patent open-secret 09-038823(JP3507208, 1995-08-01 application, 2015-08-01 expired) discloses a concept similar to the present invention, which proposes a mobius annular structure band saw, but it is a direction perpendicular to the annular surface method plane, so the maximum cutting depth can not exceed the diameter of the driving roller, and in order to provide the back support force, it sets the boss shape in the middle of the band saw to support and restrain the band saw position, resulting in the band saw can not be made very thin, the corresponding consequence is that the cutting seam is large, the cutting resistance is large, and then needs a higher power driving motor and produces lower cutting efficiency; meanwhile, the thicker saw band base body can also lead the band saw to have large rigidity and be not beneficial to overturning and bending, and the band saw is easy to fatigue fracture in the periodic overturning and cutting process.

The mobius strip was discovered in 1858 by the german mathematicians auguster mobius and john listerine, and had topological non-directionality, with only one face (surface), and one boundary. Most of the existing annular band saws are single-side annular and are not Mobius band structures, and when materials are sawed, only one side can be sawed.
