Structure and composition of special band sawing machine on construction site

The main working components of the special band sawing machine on the construction site are: base, bed, column, saw beam and transmission design mechanism, saw blade guide rail, workpiece clamping device, saw blade tensioning device, feed movement mechanism (automatic series), hydraulic transmission technology system, electrical engineering control information system, lubrication and cooling treatment system.

Applicable Materials

Band sawing machine: Band sawing machine is mainly used for sawing carbon structural steel, low alloy steel, high alloy steel, special alloy steel and stainless steel, acid-resistant steel and other alloys and metal materials. With the development of saw blade technology, ordinary automobile glass, monocrystalline silicon, gem billet gradually began to enter the sawing menu.

Type of special band sawing machine on construction site

According to the process requirements, there are two kinds of log band saw machine and split band saw machine. The log band sawing machine is the main saw of the band sawmill for cutting logs and sawing square lumber. Usually one sports car band saw or double log band saw can be used. Saw wheel diameter 1067-1829mm, up to 3658mm. On the usual single-sided sawing machine, the logs are sawed intermittently, while the sawing machine with double-sided saw can increase the work efficiency by 30%. The main contents of the sports car transmission system include economic friction rope drum, thyristor rectifier DC drive motor and hydraulic motor three kinds of continuously variable transmission design. The double band saw adopts continuous feeding mechanism such as chain conveyor and paper jam arm.

The splitting band saw machine is divided into the main band sawing machine for splitting the wool: the main band sawing machine for splitting the plate into thin plates. In addition, there are several other types of band saws:

① According to the diameter of the saw wheel and the feed mechanism, it is divided into: heavy sports car band saw with a diameter of 1524mm or more, 1067-1372mm light sports car band saw, 1067-1219mm split band saw, and 400-800mm fine woodworking band saw.

②According to the rotation direction of the saw wheel, it is divided into: the right-hand band saw machine rotates clockwise, sawing wood from the right side, rotating the band saw machine counterclockwise from the left side, and sawing wood from the right side.

③ According to the saw blade tensioning device can be divided into: double column lever type ordinary tensioning device band saw machine and hydraulic high tension cantilever band saw machine, its tension is 2~3 times of the former.

According to the relative position and direction of the two saw wheels, it is divided into vertical band saw machine, horizontal band saw machine and oblique band saw machine. Horizontal band saws are only used in China to cut plates into raw plates, and are also used in other countries to saw precious hardwood logs.

⑤ According to the combination of sawing machines, it can be divided into: single band saw machine, double band saw machine, quadruple or multi band saw machine. Double band sawing machine is divided into log double band sawing machine and wool square splitting table type double band sawing machine. Most of them are paired band saws with a combination of left and right hands, but there are also two right-handed tandem band saws, while quadruple band saws are paired band saws.

⑥ According to whether there is a cutting head, it can be divided into: ordinary band saw without cutting head, sports car band saw with single cutting head, double disc cutting head double and four band saws.
