Abstract

The invention discloses a large free forging size online measurement device and method. The device is provided with, on two sides of a forging machine, a horizontal and a vertical motion unit, a laser cast-line method length measuring unit, a temperature-measurement edge searching method diameter online temperature measurement unit, a laser correlation telemetry diameter online measurement unit, a laser correlation telemetry diameter offline measurement unit, a laser beam cast-line method diameter visual inspection and early warning unit, and an operating machine position measurement unit installed on the operating machine. Each measurement unit is installed on the horizontal or the vertical motion unit, and is capable of horizontal or vertical motion. The projection laser beam method, the infrared temperature-measurement edge searching method and the laser correlation telemetry are used in the method to obtain the forging diameter, length, size and the forging contour in a horizontal section. The device and the method achieve online and offline measurement for the forging, enhance measurement functions and improve timeliness, accuracy and efficiency of the measurement.

Description

technical field [0001] The invention relates to an online measuring device and method for the size of a large free forging piece. Background technique [0002] The on-line measurement of the size of large hot luminescent forgings is a technical problem that has not been well solved at home and abroad for a long time. The shortcomings of the current forging size measuring devices at home and abroad are that the online measurement function is not strong, the measurement accuracy and efficiency are low, the automation level is not high, and the entire forging profile cannot be output and compared with the forging process size chart. [0003] At present, the main methods for measuring the size of forgings at home and abroad include direct measurement method, laser beam line projection method, optical measurement method, laser scanning method, CCD image measurement method and structured light measurement method (see Nie Shaomin and Li Shukui published in "Metal Processing in 2008...
