Problems solved by technology

When the metal tube is deformed and the pressure of the forming tool is removed, the formed metal tube will have a dimensional change due to the metal material itself, that is, springback. Due to the uncertainty of the springback amount, manual detection has a large error and time consuming

Embodiment Construction

[0030] see Figure 1 to Figure 6 , a method for detecting the angle of a pipe bend. When a pipe bender bends a pipe, a section of the pipe bend 9 needs to be relatively fixed. This section is called the fixed section, and the section to be bent is called the bending section. It is called the included angle section, and it forms a certain included angle with the fixed section. This method detects the angle of the included angle,

[0031] Step 1, two sensors 7a, 7b are arranged beside the angled section of the elbow 9;

[0032] Step 2, after the bending section of the elbow 9 is removed from the external force and the rebound is stable, use the first stepping motor 8a and the second stepping motor 8b to drive the probes of the two sensors 7a and 7b to measure two or more different points in the angle section position information, and send the position information to the single-chip microcomputer, the single-chip microcomputer completes the calculation and displays the angle inf...

Abstract

The invention discloses a method and a device of elbow pipe angle detection. The method of the elbow pipe angle detection includes the steps of arranging two sensors besides an included angle section of an elbow pipe, using stepping motors to drive the two sensors to respectively detect position information of two point locations, sending the position information to a single chip microcomputer, finishing calculation by the microcomputer and displaying angle information on a displayer. The device of the angle of the elbow pipe detection comprises a moving assembly, the sensors, the displayer, and the single chip microcomputer. The moving assembly comprises a group of moving platforms which are overlaid, the moving directions of the moving platforms are perpendicular to each other, the sensors are arranged on the moving platform arranged at the top portion, and the moving assembly, the sensors and the displayer are respectively connected with the single-chip microcomputer. The accurate angle of bend of the elbow pipe can be displayed on the displayer, precision of elbow pipe products is improved, and precision and efficiency of production of the elbow are improved.

Description

technical field [0001] The invention relates to mechanical and electronic technologies, a bent pipe detection, especially a digital control detection method and its device. Background technique [0002] With the development of society, the demand for various types of pipe bends in all walks of life has grown rapidly. In order to ensure the installation quality of on-site pipe butt joints, the requirements for the angle accuracy of pipe bending are getting higher and higher. All this has prompted people to pay more attention to pipe bending. In-depth research on processing technology, processing equipment and testing equipment. [0003] Traditional pipe bending machines rely on manual measurement and angle control to process and produce pipe bends. This production method is very inefficient, and even the on-site pipe connection errors are large, which seriously affects the installation quality and progress of pipes. Therefore, manual measurement It has been unable to meet th...
