Description
Technical Field
The utility model relates to a hydraulic means technical field, in particular to novel broken ware of cutting of angle first nut.
Background
Bolt and nut widely used in various devices are particularly easy to corrode and seize under humid, high-temperature or corrosive environments, some screw threads are damaged due to collision or impact in the using or installing process, the nut cannot be disassembled easily due to corrosion seizing and damaged screw threads, and most common method is to directly cut the bolt and nut by flame cutting. However, in some occasions, open fire cannot be used, such as occasions requiring fire prevention and explosion prevention, some occasions only allow the nut to be broken but not damage the bolt, in this case, the nut can be disassembled only by other methods, and the hydraulic nut breaker is the best choice.
The hydraulic nut breaker has two structural forms of a flat head and an angle head.
The cutter with the flat head structure is convenient to manufacture, reliable to use and long in service life, but due to the structure of the cutter, a jack cylinder body of the driving cutter head is interfered with a square flange plate surface below a nut in some occasions, so that the cutter cannot be used. The axis of a cutter head (namely a breaking feed line) of the flat-head structure breaker is consistent with the axis of a piston rod, the outer diameter of a cylinder body of a jack for driving the cutter head is much larger than the diameter of the cutter head, when a nut is broken, the bottom of the cylinder body is inevitably positioned below the surface of a flange, when the nut close to the flange edge is broken, the cylinder body is positioned outside the flange, so that the problem does not exist, but when the nut slightly far away from the flange edge is broken, the cylinder body interferes with the flange surface, so that the nut cannot be used.
The angle head breaking and cutting device can eliminate the structural defects of the flat head breaking and cutting device, and the principle is that the rear end of a jack driving a tool bit is lifted up, so that the bottom surface of a cylinder body of the angle head breaking and cutting device is higher than the bottom surface of a frame of a body of the angle head breaking and cutting device, and the bottom surface of the body frame is ensured to be tightly attached to the surface of a flange and the cylinder body is not interfered with the surface of the flange during. The structure solves the problem that the flat head structure breaking and cutting device cannot overcome, but a new problem appears: the cylinder is lifted to enable the jack axis, namely the breaking and cutting feed line, to form a certain angle with the flange surface, the tool bit axis is not perpendicular to the side plane of the nut, a beveling situation is formed, and finally the bolt can be damaged. However, this design has solved a problem and has created a new problem: although the cutting edge line is parallel to the side face of the nut, the cutter head is obliquely fed downwards, namely, the cutter head sinks continuously in the advancing process, and the situations are as follows: one situation is that at the moment that the cutter head is close to the side face of the nut, the cutting edge covers the full height of the nut, the bottom of the cutting edge is necessarily close to the flange face, the cutter head sinks continuously in the subsequent feeding process, the cutting edge cuts into the flange body obliquely, the more the feeding is, the deeper the cutting is, the resistance force is increased sharply, finally, the cutter head cannot advance, the chopper is out of balance, and the cutting edge is very easy to break; in the second situation, the cutter head is raised (based on that the cutter head does not cut into the flange body after being cut), under the condition that the cutter head is close to the side surface of the nut, the bottom of the cutting edge is inevitably above the bottom surface of the nut, namely, one section of the lower part of the nut is not cut when the cutter head starts to be cut, the nut is not difficult to cut above the cutting edge, the resistance force is relatively small, the lower part cannot break the nut, the resistance force is sharply increased along with the slow downward cutting, the forward movement of the cutter head is finally prevented, and when the cutter head continues to be cut, the cutter can lose balance and break the cutting edge. Therefore, although the angle head breaking and cutting device solves the problem of use occasions, the actual use effect is not good, and the service life of the cutter is short.
