Description
Technical Field
The utility model relates to a tubular product plane bending test auxiliary device for the crooked preparation work of the convex test piece of corrugated metal pipe in the anti-seepage testing process after the corrugated metal pipe is crooked belongs to the civil engineering field.
Background
The experience of using metal corrugated pipes in the engineering field is nearly 200 years, and with the vigorous development of city construction in the last half century, various working conditions have prompted the demand for various metal corrugated pipes, for example, the construction industry uses metal corrugated pipes as delivery vehicles to deliver various liquids or gases. Along with the progress of construction and production activities and the progress of industry, the variety and the quality of the metal corrugated pipe are greatly improved. Generally, all kinds of metal corrugated pipes of today have the advantages of convenient manufacture, low price, good sealing performance, corrosion resistance and the like.
However, such a large number of metal bellows, which are widely used, necessarily requires quality assurance of the metal bellows. In fact, under instructive consideration, the ministry of construction in China has issued relevant detection standards for metal corrugated pipes as early as the nineties of the last century, namely JG/T3013-. Later departments such as the union of mechanical industry and the like also promulgate more significant JB/T6169-2006 Metal corrugated pipe. Until 2007, the Ministry of construction in China abolishes JG/T3013-1994 < metallic spiral tube for prestressed concrete >, and replaces the Ministry with JG 225-2007 < metallic corrugated tube for prestressed concrete >, and the standard properties of the Ministry of construction change from the original recommended instructive standard to the mandatory standard.
This standard has been used for more than 10 years to date, and extensive trial and error personnel have successively found some of the inconveniences of this standard in the course of its use. For example, the detection of the anti-leakage performance of the metal corrugated pipe after bending is very important, and the detection can most reflect the anti-leakage performance of the metal corrugated pipe after deformation caused by external force or other reasons in engineering. However, the standard JG 225-2007 metal bellows for prestressed concrete is not precise in setting up the test, and only a principle description is given simply, and the introduction and description of related instruments are lacked. After the research of documents and the market research, no mature instrument is found to complete the work of detecting the leakage resistance of the metal corrugated pipe after bending. In this regard, the authors have developed a relevant testing apparatus, a device for detecting the leakage resistance of the corrugated metal pipe for a vertical gauge building after bending, which is capable of substantially solving the problem that patent applications have been filed so far.
However, in the process of testing the leakage resistance of the bent metal corrugated pipe, a large pain point exists, namely how to bend the metal corrugated pipe into the circular arc shape required by the test accurately and quickly without damaging the pipe body. Because the arc shape of the metal corrugated pipe is influenced by the size parameters of the metal corrugated pipe, the metal corrugated pipe has the characteristics of immobility and temporality, related equipment for solving the problem is lacked at present, and the pipe sample can be bent only by means of visual measurement, ruler side or experience of a test inspector in many cases. This causes two problems, first and the accuracy of the curved arc. Secondly, the manual method easily causes the stress concentration of the pipe sample at a certain point, so that a plurality of pipes can be broken in the bending process or the hoisting process after bending.
Therefore, the utility model provides a fan formula metal bellows plane bending apparatus. The device can be used for quickly and conveniently bending the circular arc-shaped linear of the metal corrugated pipe by a single person, and the finished pipe has standard linear, uniform stress and no stress concentration. Therefore, the accuracy and effectiveness of the anti-permeability performance detection test after the metal corrugated pipe is bent are ensured to the maximum extent. Therefore, the device has extremely high application value and popularization prospect, and is a powerful assistant for pipe detection, especially for metal corrugated pipe detection.
