Band sawing machine

Abstract

A bank sawing machine comprises a machine body, wherein a saw frame is arranged on the machine body; a workbench is arranged in the saw frame; two vertical columns are arranged in the saw frame; guiding arms are arranged between the two vertical columns; a guiding seat is mounted on each guiding arm; a shockproof seat is mounted on each guiding seat; two swinging shafts are arranged in each shockproof seat; a spring is arranged between the front parts of every two swinging shafts; two rolling wheels are connected onto the rear parts of every two swinging shafts; and a saw belt clearance is left between every two rolling wheels. The bank sawing machine provided by the invention has the beneficial effects that the shock of a saw belt can be reduced and even eliminated when the bank sawing machine is in use; the shockproof effect is obvious; the service life of the saw belt is prolonged; the material section precision is improved; and the saw cutting noise is reduced.

Description

technical field [0001] The invention relates to the technical field of band sawing machines, in particular to a band sawing machine. Background technique [0002] Band sawing machine is a machine tool used for sawing various metal materials. According to the structure, it is divided into horizontal and vertical; according to the function, it is divided into semi-automatic, fully automatic and numerical control. The horizontal type can be divided into double column and scissor type. The band sawing machine is mainly used for sawing various alloys and metal materials such as carbon structural steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, and acid-resistant steel. [0003] At present, during the use of the band sawing machine, the power system of the band sawing machine will cause the saw band to vibrate, and the saw band itself will vibrate when cutting materials. Therefore, when the band sawing machine is used, the saw band will inevitably v...

Problems solved by technology

[0003] At present, during the use of the band sawing machine, the power system of the band sawing machine will cause the saw band to vibrate, and the saw band itself will vibrate when cutting materials. Therefore, when the band sawing machine is used, the saw band will inevitably vibrate. , and the vibration of the saw band has a great impact on sawing, especially for sawing machines with increased width, the vibration of the saw band will cause rough cut surfaces, the teeth will wear out quickly and become blunt, and the life will be shortened. At the same time, the vibration of the saw band will make abnormal noise , forming noise, the actual application effect is not ideal

[0004] The Chinese invention patent with the patent number of 201510257252.7 discloses a saw blade damping mechanism, which achieves the shock absorption effect by pressing the saw blade with a pressing block. The reaction force and pressure on the saw blade are too large, which will easily damage the saw blade and reduce the service life of the saw blade
