Problems solved by technology

This patent also does not consider the fatigue strength of the saw blade, nor can it make full use of the power driving the main motor
On the other hand, the patent also fails to realize that the tension force of the saw blade is not directly proportional to the sawing resistance force. Based on this feedback control, the control of a given sawing force cannot be effectively realized.

Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034]A band saw generally includes a saw frame system and a feed system. The saw frame system mainly includes a driving wheel, a driven wheel, and a saw blade set on the outer ring of the main and driven wheels. The main motor drives the driving wheel to rotate, and the friction between the driving wheel, the driven wheel and the saw blade drives the saw blade to run along. A tensioning oil cylinder is arranged at the driven wheel, and the tensioning oil cylinder adjusts the tension degree of the saw blade between the driving wheel and the driven wheel, thereby ad...

Abstract

The invention relates to an optimization method of a reference saw cutting force of a saw blade of a band sawing machine. The optimization method comprises the steps: calculating a rated saw cutting force Fx0 according to Formula (A), calculating a theoretical saw cutting force Fx1 according to Formula (B), carrying out fatigue parameter checking calculation on the initial saw cutting force Fx1 of the saw blade to allow Fx1 to meet Formula (C), calculating a limit saw cutting force Fx2 of the saw blade according to Formula (D), and taking a minimum value of the three saw cutting forces as the reference saw cutting force Fxc. The method makes full use of power of a main drive motor, considers influence of a saw cutting working condition on the service life of the saw blade and limiting cases of feeding forces of different materials, optimizes the reference saw cutting force, and takes the reference saw cutting force as a control reference of the saw cutting force, realizes intelligent saw cutting of the band sawing machine and effectively prolongs a fatigue life of the saw blade.

Description

technical field [0001] The invention relates to the technical field of band sawing machines, in particular to an optimal method for the reference cutting force of saw blades of band sawing machines. Background technique [0002] Modern manufacturing industry is developing towards high efficiency, high precision and economy. As the starting point of metal cutting, sawing has become an important part of the process of parts processing. There is a big gap between domestic band sawing machine products and foreign advanced band sawing machine products, especially the problems of low intelligence and low sawing efficiency. As the first process of parts processing, the effect and efficiency of sawing often affect the efficiency of the entire production line. Improving the sawing efficiency of band sawing machines can prevent sawing from becoming the bottleneck of the entire production line. [0003] At present, the control method of constant power sawing of metal cutting band sa...
