Abstract

The invention discloses a ratchet type sealing welding ring cutter. According to the ratchet type sealing welding ring cutter, the welding line cutting precision is high, the time is saved, and equipment body is not easily damaged. The ratchet type sealing welding ring cutter comprises an inner ring used for cutting a sealing welding ring; a first opening used for allowing the sealing welding ringto extend thereinto is formed in the inner ring; the inner ring comprises an upper inner ring and a lower inner ring connected to the upper inner ring, and two first rolling wheel are clamped betweenthe upper inner ring and the lower inner ring; a cutter head used for cutting the sealing welding ring is arranged between the two first rolling wheel, a screw rod is arranged on one sides of the first rolling wheel, and a screw rod nut is arranged on the screw rod; and the screw rod nut is connected to a positioning rod, a second rolling wheel is arranged at the end part of the positioning rod,and the connecting lines among the two first rolling wheels and the second rolling wheel define a triangle for clamping the sealing welding ring.

Description

technical field [0001] The invention belongs to the technical field of hardware, and in particular relates to a ratchet type seal welding ring cutter. Background technique [0002] Now in some factories with high leakage level, such as nuclear power plants, the flange sealing of field equipment uses a large number of sealing welding ring welding seals. When these devices need to be repaired, the sealing welding ring needs to be cut to disassemble the flange. [0003] The existing sealing welding ring cutting technologies are manual sawing bow sawing and grinding machine grinding. Manual sawing bow sawing cannot accurately locate the exact position of the sealing welding ring. After cutting, the cutting range is wide, which is easy to damage the flange body. It is often difficult to use when the flange position is not good, and it takes a long time; although the grinding machine can quickly remove the welding meat, the equipment body is often also polished at the same time, ...
