Background

The saw band centering device of the conventional band sawing machine clamps and centers the saw band by adopting 2 alloy blocks, and meanwhile, the saw band feeding force is provided by pressing the back of the saw band by one alloy block, and all the saw band and the alloy blocks are in sliding friction. The alloy blocks are easy to wear, and the maintenance and replacement cost is high. Secondly, in the use process of the band sawing machine bearing, friction between the saw band and the alloy block can be abrasion of the saw band, and the service life of the saw band is influenced. Thirdly, the alloy block is not a standard component, and has small market production scale and high price. Fourthly, the alloy blocks are worn quickly, the saw belt has poor righting effect, the broken material is askew, the material is wasted, and the processing allowance of the subsequent production is increased. On the contrary, if the saw band centralizer has good righting effect and is wear-resistant and durable, the semi-finished product produced and processed by the band sawing machine has more regular appearance and more accurate and stable size, and is more beneficial to controlling the material cost. Especially in the environment of mass production, the cumulative effects of material waste and processing efficiency are obvious, and the improved economic benefit is great.

The band sawing machine is a special machine tool for cutting raw materials, which is generated along with the development of the mechanical industry, and is widely applied to sawing metal and nonmetallic materials. The driving wheel on the band sawing machine rotates to drive the saw blades wound on the driving wheel and the driven wheel to rotate, and the driving wheel and the driven wheel are obliquely arranged, so that the saw belt guiding and centering device is required to be arranged to adjust the direction of saw teeth of the saw belt so as to realize sawing.

The Chinese patent (patent number TW 111200840U) invents a saw belt guide pekinetin seat; the device comprises a pekine mount and a guide piece, wherein the pekine mount comprises a mount body, two first bearing assemblies and a second bearing assembly, the mount body is integrally formed into an L shape by powder metallurgy, the first bearing assemblies and the second bearing assemblies are all arranged on the mount body, a limit groove is axially formed in the bottom position of the guide piece, two clamping pieces are formed on two sides of the limit groove, the guide piece is fixedly arranged on a base, and the clamping pieces are parallel to side columns; by means of the structure, the seat system of the pekinetin seat is directly formed integrally by powder metallurgy, the precision after manufacturing is high, the manufacturing speed is high, the processing cost is also reduced, the friction of the saw belt can be reduced by the first bearing component and the second bearing component, the position of the saw belt can be limited by the clamping piece, and the stability of the saw belt is improved to a certain extent. However, due to the design structure of the saw belt pekinetin seat designed by the TW111200840U, the saw belt angle adjusting process at the outer circle of the working section and the local belt wheel of the saw belt is too severe, so that the saw belt is greatly distorted before and after passing through the pekinetin seat, and the saw belt is continuously distorted and aged in the circulating working process, so that the service life of the saw belt is greatly influenced.
