Bending angle measuring mechanism for metal bent pipe

Abstract

The invention discloses a bending angle measuring mechanism for a metal bent pipe, which comprises a convertible angle rotating unit, a clamping unit and a supporting unit, and is characterized in that the clamping unit is arranged on the convertible angle rotating unit and can move along the convertible angle rotating unit; the convertible angle rotating unit is fixed on the supporting unit. Bentpipes with any bending angle can be placed by adjusting the included angle between rotating plates, and the mechanism is convenient and fast to use and is not limited by the bending angle; the mechanism adopts modular design, the position of the bent pipe can be positioned and adjusted by adjusting the rotating plates and a clamping module, and convenience, quickness, accuracy and high flexibility are achieved.

Description

technical field [0001] The invention relates to the field of curved pipe measurement, in particular to a bending angle measuring mechanism of a metal curved pipe. Background technique [0002] Metal pipe fittings are bent and formed, usually by determining a reasonable fulcrum and force point, and applying a certain bending moment or bending force to make it bend and form. However, after the pipe bending process is completed, the elastic deformation contained in the deformation area of ​​the elbow is unloaded, which causes the pipe to rebound, and the stress state inside and outside the elbow is opposite. When unloading, the springback effects are superimposed and the bending angle decreases. , the bending angle after the springback of the elbow and the bending angle before the springback have a deviation, which seriously affects the dimensional accuracy and assembly efficiency of the elbow. In order to effectively compensate the springback and judge whether the forming angl...

AI Technical Summary

Problems solved by technology

For bent pipes, the existing angle measurement devices are more complicated in fixing and positioning, and the positioning time is longer, so fast measurement cannot be performed, and the structure of the measuring device is relatively complicated, which is prone to damage, which is not conducive to popularization and use.
