Saw band tensioning mechanism of high-speed band sawing machine and adjusting method of saw band tensioning mechanism

Abstract

The invention discloses a saw band tensioning mechanism of a high-speed band sawing machine, and relates to the field of machining equipment. The saw band tensioning mechanism of the high-speed band sawing machine comprises a sawing machine base, a saw band body and a saw band tensioning device, the saw band tensioning device comprises a tensioning gear body, the tensioning gear body is arranged in a saw band supporting and fixing frame, and a supporting and adjusting mechanism corresponding to the tensioning gear body is arranged above the saw band supporting and fixing frame. When the saw band tensioning mechanism of the high-speed band sawing machine is used, cutting operation on materials is facilitated, a used mechanical arm body can drive the whole saw band supporting and fixing frame and the saw band body to move, the saw band body is used for cutting the materials, in the using process of the saw band body, as time goes on, the saw band body can be gradually loosened, after the saw band body is loosened, the saw belt body can be tensioned conveniently and rapidly, the tensioning effect is good, and the whole tensioning mechanism is simple in structure, convenient to use and free of manual operation.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a saw band tensioning mechanism for a high-speed band saw machine. Background technique [0002] Band sawing machine is a machine tool used for sawing various metal materials. According to the structure, it can be divided into horizontal and vertical, according to the function, it can be divided into semi-automatic, fully automatic, numerical control, and the horizontal can be divided into double column and scissors; After a long time of use, the saw band will loosen with the hands, so the band saw machine is provided with a tension wheel near the saw band. [0003] In the prior art, when adjusting the tensioning wheel, manual adjustment is generally used. This adjustment method has the following problems. The manual adjustment accuracy is not high, it is difficult to grasp the strength, and it is time-consuming and laborious. The existing tensioning whee...

Problems solved by technology

[0003] In the prior art, when adjusting the tensioning wheel, manual adjustment is generally used. This adjustment method has the following problems. The manual adjustment accuracy is not high, it is difficult to grasp the strength, and it is time-consuming and laborious. The existing tensioning wheel may also have the problem of direction deviation during adjustment, and its lateral support strength is not good, and the tension effect on the saw band is not good. If the above problems occur, the entire saw band may also appear In the case of dislocation, danger occurs, and after the tensioner is adjusted, there is generally no corresponding safeguard measure, and the effective fixation of the tensioner cannot be guaranteed, so that the transmission part may be damaged due to excessive force. For the existing technology In order to solve the above-mentioned problems
