A device for removing corroded fastening dead nuts

Abstract

The invention discloses a device for dismounting a rusted fastened screw nut. The device comprises a base, a fixing bracket, a screw nut wrench, a cap combining wrench, a jack device, an adjusting bolt and a jackscrew, wherein two fixing blocks are arranged at the top of the fixing bracket; the jack device and the adjusting bolt are respectively positioned on two sides of the fixing bracket; an adjusting bolt fixing block is arranged on one side facing to the adjusting bolt, of the fixing bracket; a second threaded through hole is formed in the adjusting bolt fixing block; the adjusting bolt is in threaded connection with the second threaded through hole; the opening of the screw nut wrench and the opening of the cap combing wrench are both positioned between the two fixing blocks; the tail part of the screw nut wrench contacts the lifting output end of the jack device; the tail of the cap combing wrench contacts the head of the adjusting bolt. By adopting the device, a rusted fastenedscrew nut is dismounted by using a jack smartly, the defect that the rusted fastened screw nut is violently dismounted by using a wrench at present is avoided, safe and efficient production can be ensured, both the labor and the force can be saved, and in addition, screw rods and screw nuts can be relatively well maintained.

Description

technical field [0001] The invention belongs to the technical field of nut removal devices, and in particular relates to a device for removing corroded and fastened dead nuts. Background technique [0002] In the rolling mill workstation of the SCR continuous casting and rolling copper rod production line, each station is equipped with rolls, which need to be used in a fixed size for processing copper rods. Due to the high extrusion force, it is easy to cause the rolls to move, and each of the fixed rolls The rollers are all clamped with screws. The copper nut on the screw can fasten the roll, and the cap can prevent the copper nut from loosening. Due to the high-temperature production conditions, the emulsion and some impurities adhere to the screw for a long time, which easily leads to corrosion of the screw, and the nut and cap on the screw are too tight, which is extremely difficult to disassemble. [0003] The way and angle of the nut and cap on the original dismantle...

Problems solved by technology

The disadvantages of this disassembly method are low work efficiency, long shutdown time, and waste of manpower and material resources; the use of heavy hammers can easily cause serious damage or damage to equipment and tools, increase the difficulty and cost of equipment maintenance, and the labor intensity of workers is high; , because the screw is not fixed, under the impact of the hammer, it is easy to fly out and hurt people and equipment, which poses a great safety hazard
