Wire saw and wire saw automatic control method

Abstract

The invention relates to a wire saw and a wire saw automatic control method, which realizes the automation of the cutting process on the basis of the existing wire saw cutting system scheme, monitors the system operation information in the cutting process in real time, and takes the optimal cutting efficiency as the control target , realize automatic adjustment of cutting speed and cutting tension, and monitor and protect various abnormal states that may occur in system operation. Compared with the prior art, the system and method of the present invention can quickly respond to the change of the cutting load and effectively improve the cutting efficiency; while improving the degree of automation of the cutting operation, the human intervention in the cutting process is reduced, and the labor cost is reduced; and It can also automatically respond quickly to equipment abnormalities, reduce equipment failure rate and failure time, and improve production safety.

Description

technical field [0001] The invention belongs to the technical field of automation control, in particular to the field of cutting equipment, and in particular to a wire saw and a wire saw automatic control method. Background technique [0002] A wire saw is a device that uses a special rope (hereinafter referred to as a rope), such as a rope embedded with diamond beads, to move around the object to be cut at high speed to cut the object. The equipment was originally mainly used for mining stone in mines. With the continuous development of related technologies, its application has now been extended to stone processing, block shaping, metal processing, building renovation, building demolition and other fields. Due to the characteristics of low loss, high efficiency and wide application range, the related technology has good application and development prospects. [0003] When the wire saw is working, the rope is wrapped around the pre-designed fracture of the object to be cut,...

AI Technical Summary

Problems solved by technology

The actual operation is difficult and requires high operator experience, and it is difficult to find the best matching working point of cutting speed and cutting tension through manual adjustment

Especially when the material of the object to be cut is uneven (for example, when cutting reinforced concrete members, the load will change suddenly when encountering steel bars), it is necessary to constantly adjust the cutting speed and cutting tension, which not only wastes manpower, but also cannot achieve fast and accurate adjustment

In this way, on the one hand, if the load suddenly increases, but the cutting speed or cutting tension is not lowered in time, it may cause the equipment to stop due to overload protection, affect work efficiency, and may damage the rope and equipment in severe cases, and even cause safety accidents; on the contrary, On the other hand, if the load suddenly decreases, but the cutting speed and cutting tension are not adjusted in time, it will cause the operation of the equipment to fail to reach the desired power upper limit, and the cutting efficiency will decrease

[0013] In summary, the existing wire saw cutting system has problems such as low degree of automation, low production efficiency, high labor cost, high equipment failure rate, and poor safety.
