Problems solved by technology

However, under harsh working conditions or working for a long time, the lubricating fluid with impurities in the pit cannot be effectively discharged, resulting in greatly weakened lubrication and pressure bearing capacity after accumulation, and there is no correlation between the surface texture and the friction pair of the band saw blade.

Embodiment 1

[0041] Such as image 3 As shown, the pits are arranged in two rows along the circular direction of the saw blade of the band sawing machine, and the distance between any two pits in the same row is equal; the pits are rectangular on a plane parallel to the surface of the saw body; the bottom of the pits is along the vertical band. For the straight line segment in the circular direction of the saw blade of the sawing machine, the included angles between the two side surfaces and the surface of the saw body are equal and range from 1° to 5°. In this embodiment, the angle is 3°. The area of ​​the pit on the surface of the saw body is 3mm 2 . The lubricating fluid enters the pit to form a lubricating film between the band saw blade and the workpiece; the inclined side of the pit makes the lubricating fluid tend to be thrown out when the band saw blade is sawing at high speed, thereby providing support for the band saw blade; After the cutting is completed, the lubricating fluid...

Embodiment 2

[0043] Such as Figure 4 As shown, the pits are arranged in two rows along the circular direction of the saw blade of the band sawing machine, and the distance between any two pits in the same row is equal; the pits are rhombus-shaped on the plane parallel to the surface of the saw body; For the straight line segment in the circular direction of the saw blade of the sawing machine, the included angles between the two side surfaces and the surface of the saw body are equal and range from 1° to 5°. In this embodiment, the angle is 3°. The area of ​​the pit on the surface of the saw body is 3mm 2 .

Embodiment 3

[0045] Such as Figure 5 As shown, the pits are equidistantly arranged along the circular direction of the saw blade of the band sawing machine; the pits are composed of two grooves that are triangular on the plane parallel to the surface of the saw body and arranged along the direction of the circular direction of the vertical band saw blade. The three sides of the triangle appearing on the plane parallel to the surface of the saw body are set in parallel, but facing oppositely; the two grooves are not connected; the angle k between the bottom of the groove and the surface of the saw body is 0-5°, when k≠0, The minimum depth of the intersection surface between the bottom of the groove and the saw body is 0 (that is, the intersection surface and the surface of the saw body are intersected), and the maximum depths of the two grooves are located on different sides; k=0 in this embodiment (that is, the groove The bottom is parallel to the surface of the saw body, and the depth of...

Abstract

The invention discloses a groove-type-structure band saw sawing device based on bionics. The non-smooth-form surface has better abrasion resistance; during a bad working condition or long-time work, lubricating liquid with impurities in pits can not be effectively discharged, lubricating capacity and pressure bearing capacity are greatly reduced after accumulation, and reporting of related researching and applying of a surface texture in the aspect of band-sawing-machine saw blade friction pairs does not exist. The groove-type-structure band saw sawing device comprises a band-sawing-machine saw blade, a driving wheel, a driven wheel and guide columns. A plurality of pits are formed in the surface of a saw body of the band-sawing-machine saw blade, the maximum depth of the pits ranges from 0.01 mm to 1 mm, and the pits are of bionics groove-type structure. According to the groove-type-structure band saw sawing device, texture processing is carried out on the surface of a band saw, lubricants are stored, and the cutting contact area of the band saw is reduced so that the cutting performance of the band saw can be improved. Meanwhile, due to the gradient of the pits, lubricating liquid in the pits can be replaced and supplemented in time, the lubricating effect on the band saw is greatly improved, and the service life of the band saw is prolonged.

Description

technical field [0001] The invention belongs to the technical field of band saw cutting devices, relates to a band saw blade, in particular to a novel band saw blade based on bionics and having a special groove structure. Background technique [0002] With the development of modern manufacturing industry, metal band sawing machine, as the equipment required for the first process of mechanical processing and manufacturing, has become an important part of the part processing process. Due to its fast cutting speed, high processing precision, and less material loss , has been widely used, but at present many domestic band sawing machines have various problems, such as severe heat generation of the saw blade, low sawtooth strength, and fast wear of the saw body, which have always been important factors affecting its high-end. [0003] At the same time, tribology has been developed by leaps and bounds. Many experts and scholars have found that the two surfaces in contact with each...
