Description

Guard bar pipe water cutting anti-deformation clamp Technical Field The utility model relates to the technical field of water cutting clamps, in particular to a guardrail pipe water cutting deformation-preventing clamp. Background The guardrail is a fence structure for isolation, protection or decoration, is mainly applied to scenes such as roads, bridges, balconies, municipal works and the like, has the core functions of ‌ for safety protection, traffic guidance, area division and environment beautification, and is a main structural material for manufacturing the guardrail. However, in the prior art, in the aspect of industrial cutting technology, the existing technology has low cost and easy operation, so that the technology becomes a mainstream cutting mode, when the guardrail tube is cut by using water cutting, the guardrail tube can vibrate under the influence of high-pressure water flow impact in the water cutting process, and because the guardrail tube is generally hollow and generally lacks damping measures for the interior of the guardrail tube when being cut, the vibration can be amplified when the guardrail tube is cut, so that the guardrail tube can be deformed when being cut. Disclosure of utility model The utility model aims to solve the defects in the prior art that the guardrail tube is affected by the impact of high-pressure water flow and vibrates in the water cutting process, and the guardrail tube is generally hollow and lacks damping measures in the guardrail tube when being cut, so that the vibration can be amplified in the cutting process, and the cut can be deformed.
