Saw band vibration eliminating structure of high-speed band sawing machine

Abstract

The invention relates to a saw band vibration eliminating structure of a high-speed band sawing machine and belongs to the field of mechanical processing equipment. The vibration phenomenon of a saw blade of the existing band sawing machine is serious in the cutting process, so cuts of processed workpieces are deflective, and in addition, the saw blade breakage can be frequently caused. The saw band vibration eliminating structure comprises a saw bow, a gantry cross beam, a fixed base, a numerical control system, a saw blade moving mechanism, a saw blade clamping mechanism, a tensioning mechanism, a tensioning oil cylinder and a saw bow moving mechanism, wherein the gantry cross beam is arranged on the fixed base, the saw bow and the gantry cross beam are assembled together, the saw blade moving mechanism, the saw blade clamping mechanism, the tensioning mechanism and the tensioning oil cylinder are respectively arranged on the saw bow, the tensioning oil cylinder is connected with the tensioning mechanism, the saw bow moving mechanism is arranged on the gantry cross beam, and the saw bow moving mechanism used for driving the saw bow to vertically move along the gantry cross beam is connected with the saw bow. The saw band vibration eliminating structure of the high-speed band sawing machine has the advantages that the vibration phenomenon of the saw blade can be lightened, the cutting quality of the processed workpieces is improved, the breakage phenomenon of the saw blade is reduced, and the stable and high-speed cutting on the workpieces is realized.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a structure for eliminating the vibration of the saw band of a high-speed band saw machine. Background technique [0002] The saw blade of an ordinary band sawing machine is tightened by the driving wheel installed on the bow and the driven wheel assembled on the tensioning mechanism. The driving wheel is connected to the reducer, and the reducer is connected to the ordinary motor. The tensioning mechanism is installed on the bow. Installed on the driving wheel and the driven wheel, with the operation of the ordinary motor, the ordinary motor drives the reducer, the reducer drives the driving wheel, and the driving wheel drives the driven wheel through the saw blade, so that the saw blade rotates at a constant speed. The saw bow part is moved up and down by the counterweight oil cylinder, so that the saw blade can be fed up and down, and the band sawing machine can ...

AI Technical Summary

Problems solved by technology

Since the ordinary motor and the counterweight cylinder (hydraulic system) control the movement speed and feed rate of the saw blade with low precision, the movement and feed accuracy of the saw blade cannot be guaranteed, thus accumulating irregular unreleased energy on the saw blade During the process, the vibration of the saw blade is serious, which makes the incision of the processed workpiece deflected, and often causes the saw blade to break
