Description

A tool and method for rapid detection of misalignment of structural forgings

technical field

The invention belongs to the detection technology of structural forgings, in particular to a tool and method for rapidly detecting the misalignment of structural forgings.

Background technique

Displacement refers to the relative displacement along the direction of the parting surface between any corresponding points on both sides of the parting surface in the forging. Calculated by A=(b2-b1)/2, where b1 and b2 are the minimum and maximum projected lengths or widths measured parallel to the main parting plane, in millimeters (mm). Misalignment is a key factor affecting the quality of forgings in the forging process. To ensure the quality of structural forgings, misalignment must be controlled. Due to the influence of forging equipment, die bases, molds and other process factors, misalignment will definitely occur. In order to control the misalignment, the actual misalignment of structural forgings must be measured first. Along the periphery of the parting surface, the local wear of the forging die, the change in the thickness of the forging, and the detection error directly affect the measurement accuracy of the offset value, resulting in difficult to judge the offset value of the structural forging in actual production.
