Analysis and treatment of broken wire saw of granite mining wire saw

The diamond wire saw is a flexible cutting tool, which is mainly supported by wire rope as the core of the overall structure. If the wire rope is broken, it will directly cause the broken rope of the wire saw. If the wire rope breaks, the two broken wire ropes can continue to be plied through the joint. But this situation will lead to the disconnection of the joint. In the following, we will analyze the two situations of broken diamond wire saw rope at the joint and broken diamond wire saw rope at the non-joint (wire rope in the middle of beads.

Diamond wire saw rope breaking at joint

Most of the reasons for the broken diamond wire saw rope at the joint are due to the extraction of the joint. Very few reasons are that the diamond wire saw beads at the joint move and wear and tear. Finally, due to long-term wear, the joint is worn and broken. The specific reasons are as follows:

1. The size of the connector is incorrect. The main reason is that the joints used to connect the wire ropes are too large. This situation is not common. The broken diamond wire saw rope caused by the wrong diameter of the joint mostly occurs in this situation that some novice operators do not know much about the docking diamond wire saw rope. The solution is very simple, it can be matched with a suitable caliber joint. The best practice is that the diamond wire saw manufacturer send some suitable joints when a customer buys the diamond wire saw. The diamond wire saw products of JIANGXI LINSING Diamond Tools Co., Ltd. will give some free diamond wire saw joints according to the customer's requirements.

2. The crimping clamp is not suitable for die diameter. If the diameter is too large, the pressure will be insufficient. If the diameter is too small, the "big ears" will be pressed out, causing the joint to crack and the rope to break. It is also easy to deal with this situation that you just need to purchase a crimping clamp that matches the size of the pressing die. In order to better match the pressing die, it is recommended to find the same purchaser as the pressing die to prevent the inconsistency of the size of the crimping clamp and the joint.



3. The rubber which needs to be peeled as the joint on the diamond wire saw rope is not peeled off cleanly, resulting in a weak crimping force between the joint and the diamond wire rope. This situation is very common. Therefore, it is necessary for the operator to peel off the rubber from the mining wire saw as cleanly as possible in the early stage of the diamond wire saw rope knotting, which can be assisted by tools such as a utility knife and a needle-nose vise.

4. The cutting time is long, and the joint itself wears seriously, resulting in breakage. This occurs in granite mines that cut large surfaces. Due to long-term cutting, the diamond wire saw beads are consumed excessively, and the joints begin to rub against the stone. Long-term friction of the joints will gradually thin the joint wrapping layer. When the alloy layer is worn out , which will naturally lead to broken diamond wire saw ropes. There are two solutions to this situation: one is to increase the number of turns of the diamond wire saw rope in order to increase the friction surface, thereby reducing the wear of the joint, and the other is to replace the new diamond wire saw rope.

5. During the cutting process, the improper setting of the cutting process will cause the saw machine to shake frequently, which leads the joint to come out. On the other hand, the current is too high, resulting in too much power. During the process of cutting granite, the joint cannot withstand the strong pulling force, which causes the rope to break. The solution to this situation is also very simple: reducing the working current of the diamond wire saw machine, and keeping the diamond wire saw machine running smoothly during the cutting process.

Wire rope breaking in the middle

1. The diamond wire saw suddenly pressed by the stone when cutting, and the wire rope breaks under the tension of the instantaneous high speed. The solution is to increase the cutting gap as much as possible to enhance the support during the cutting process.

2. During the use of the diamond wire saw, one or several diamond wire saw beads rotate (also call loosen), and the diamond wire saw beads wear out the steel diamond wire saw rope until the diamond wire saw rope breaks. This situation often occurs. The main solution is to conduct shutdown inspections in a timely manner, to know the situation of each diamond wire saw bead and the situation of the joint, and to avoid some follow-up troubles.



3. Because the cooling water did not keep up, the dry grinding causes the rubber to crack and the steel wire to break during the cutting process. When this situation happens, it is necessary to increase the flow of cooling water in time to keep the diamond wire saw beads at a suitable temperature, thereby reducing the possibility of rubber aging and deformation.
