Mine nut cutters are divided into mine nut cutters and integrated nut cutters, also known as mine nut cutters. For corroded nuts that cannot be disassembled, the nut cutter can be used to cut them easily, and there is no damage to the anchor rod, so that it can be used next time. The method of forcibly breaking the nut with a hard object has also caused damage to other parts to a certain extent. At this time, the role of the mining nut breaker is reflected.
Bolts and caps (nuts) widely used in industrial production are exposed to high temperature or corrosive environments in the open air. Some are bitten by rust, and some are damaged due to being hit. In short, there is a problem. It is very difficult to remove the nut. In the past, it was common to use (gas) welding to cut off the nuts and bolts together. However, in some special working conditions, it is sometimes prohibited to use fire (electric) welding operations, such as pulverized coal bins and oil pipelines in power plants. In high-pressure and high-temperature pipelines, it is even more helpless to replace the nut and bolt. The hydraulic nut breaker can not fire, electricity or damage the bolt thread. It is simple, fast, safe and efficient to solve the disassembly of the bolt and nut And replacement puzzles.
The structure of the mining nut cutter is relatively simple. It is similar to a single-opening torx wrench. Its inner ring is smooth, the handle is hollowed out, and there is a straight shank steel bar with a tapered head. When rotating inward, the steel bar is pushed out to achieve strength against the nut. By vigorously holding the nut, the nut cannot withstand huge pressure and burst, and the operation of splitting the nut is completed. Of course, the nut splitter is required to cover the nut , Use the wrench to clamp the hexagonal head screwed into the tail of the rod, and apply force to split the nut easily.
How to use mine nut cutter:
1. Open the oil injection screw plug, fill the manual oil pump box with 20 # engine oil, or hydraulic oil, and switch the unloading valve.
2. Put the head hole of the splitter into the nut to be split and lay it flat.
3. The manual oil pump pushes the cleaver forward to the nut. Note that the pressure gauge shows zero before the cleaver does not reach the nut. The pointer starts to rise after the nut is cleaved. The cleaver pushes into the nut. When the cleaver is pushed over Suddenly, the cleaver quickly split the nut to damage the bolt thread.
4. When the cracking sound of "pit" is heard, it indicates that the nut has been split, and at the same time, the pointer of the manual oil pump pressure gauge quickly returns to zero, that is, the pressure stops.
5. Unscrew the unloading valve, return to the original position after splitting the knife, remove the splitter, and the work is over.
6. Some nuts can also be split with a knife on the opposite side of the split, so that it is divided into two halves and separated from the bolt.
The above is the related knowledge content about mining nut cutter for friends. The power source of the split nut cutter is a hydraulic pump (manual, electric or pneumatic), which has large breaking force, good performance, safe and convenient use and simple maintenance. The integrated nut cutter is compact in structure, relatively light in weight, easy to carry, reliable in performance, safe and convenient to use, and simple to maintain.
