Metal corrugated pipe bending tester and test method thereof

Abstract

The invention discloses a metal corrugated pipe bending tester and a testing method thereof. The metal corrugated pipe bending tester comprises a square frame column, and a plurality of arc-shaped grooves with different sizes are formed in each side face of the square frame column. According to the metal corrugated pipe bending tester, the square frame column is adopted, the arc-shaped grooves of multiple specifications are formed in each column face, the metal corrugated pipe bending tester can adapt to bending of metal corrugated pipes of different specifications, the bending efficiency is improved, the equipment cost is reduced, the vertical structure is adopted, and manual bending is also facilitated;when the length of the metal corrugated pipe is 1.5 m, the lower end of the metal corrugated pipe is clamped into the groove to serve as a supporting point; the upper side of the metal corrugated pipe is slowly pressed and bent and gradually pressed into the arc-shaped groove, compared with horizontal bending, operation is more convenient, clamping is more time-saving and labor-saving, local damage of the metal corrugated pipe (the metal corrugated pipe formed by spirally winding an iron sheet, and water leakage is prone to occurring in a gap between the wound inner layer and the wound outer layer) is avoided, and the measurement stability is improved.

Description

technical field [0001] The invention relates to a metal bellows bending tester and a testing method thereof, belonging to the technical field of metal bellows bending equipment. Background technique [0002] The anti-leakage performance test of metal bellows for prestressed concrete needs to bend the metal bellows specimen, take it off after bending, seal the lower end with water or cement slurry, and check the water seepage on the surface of the metal bellows. Most of the models use a single groove corresponding to a diameter, resulting in many models and inconvenient transportation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metal bellows bending tester and its testing method to solve the above-mentioned problems in the prior art. [0004] The technical solution adopted by the present invention is: a metal bellows bending tester, which includes a square frame column, and each side of the square frame co...
