Abstract

The invention discloses an angle control device for a bending pipe. The angle control device comprises a supporting frame, a fixing device, an infrared thermal imager, a distance measuring sensor anda computer, wherein the supporting frame is supported on one side of a bending machine, the fixing device is arranged on the supporting frame, and the infrared thermal imager and the distance measuring sensor are fixed on the fixing device; and a lens of the infrared thermal imager is opposite to the working surface of the bending machine, a signal emitting end of the distance measuring sensor isopposite to a positioning point on the bending machine, the infrared thermal imager is connected with a first port of the computer through a signal line, and a second port of the computer is connectedwith a control cabinet of the bending machine through a signal line. According to the angle control device for the bending pipe, temperature and angle parameters before and after bending of the bending pipe can be collected, a database of bending process parameter groups of the bending pipe is established, and the control over the angle of the bending pipe is realized by calling the parameter groups of the database.

Description

technical field [0001] The invention relates to the technical field of pipe bend production equipment, in particular to a pipe bend angle control device. Background technique [0002] Pipe bending is widely used in various engineering fields such as machinery, shipbuilding, petroleum, construction, etc. The heat-simmering pipe bending process of medium frequency induction heating is currently the most widely used production process with the highest economic benefits. Due to the deformation after cooling and the rebound of the metal material, the bend angle produced by this process has a large deviation, and it is difficult to control with traditional processes and technical means. Due to the large angle deviation, the elbow will inevitably be forcibly corrected to the required angle at the installation site during installation, which makes the inside of the pipe wall bear tensile and compressive stress for a long time, and under the impact or pressure of the fluid inside the...
