Problems solved by technology

The hydraulic nut cutter can easily cut nuts. However, when cutting nuts, the force point of the cutter is often not aligned with the center line of the hydraulic push rod, that is, the piston rod of the hydraulic cylinder. On the line, breaking the nut will generate a large torque, so after a period of use, the hydraulic cylinder will be damaged

Abstract

The invention relates to a nut splitter, which comprises a main body frame, a hydraulic cylinder, a sliding block, a movable knife and a fixed knife, wherein the hydraulic cylinder is fixedly installed on the main body frame; the main body frame is provided with one pair of guide slots; two ends of the sliding block are matched with the guide slots and are respectively arranged in the guide slots; two ends of the sliding block can slide in the guide slots; the sliding block and the piston rod of the hydraulic cylinder are fixedly connected; the movable knife is fixedly connected with the sliding block; the fixed knife is fixedly installed on the main body frame. According to the nut splitter disclosed by the invention, fire and electricity are not used, bolt screw threads are not damaged, and therefore the difficulty of disassembling and replacing bolts and nuts can be conveniently, quickly, safely and efficiently solved.

Description

technical field [0001] The invention relates to the technical field of nut removal tools; in particular, the invention relates to a nut cutter. Background technique [0002] Nuts widely used in industrial production are exposed to high temperature or corrosive environments in the open air. Some are rusted to death, and some are damaged due to bumping. In short, it is very difficult to disassemble the nuts if there is a problem. In the past, the nuts and bolts were usually cut off by gas welding. However, in some special working conditions, it is sometimes strictly forbidden to use fire (electric) welding operations, such as coal powder bunkers in power plants, high-pressure and high-temperature pipelines in oil pipelines, etc. At the same time, it is even more helpless to replace the nuts and bolts. [0003] Concrete sleeper spike nuts will corrode on the spike bolts due to maintenance and environmental reasons and cannot be removed. If the bolts are damaged by gas welding,...
