Embodiment

[0076] The geometric dimensions of the square thick-walled pipe fittings are 8000mm in total length, 14mm in wall thickness, and 80mm×80mm in section size. Feed the pipe to the table top of the straightening machine, and the straightness detection device detects the upper surface of the pipe from left to right. Set the first detection point on the left as the coordinate point O(0, 0), and cross the point to be parallel to the The straight line of the table top of the leveler is the x-axis, and the line perpendicular to the table top of the leveler is the y-axis, and the original plane rectangular coordinate system is established. The straightness detection device is spaced at a fixed distance of 20mm along the pipe to detect and obtain the coordinate data of each position on the upper surface of the profile (x i ,y i ), i=1,2,...,401.

[0077] First, calculate and determine the overall straightness:

[0078] The overall straightness of the profile is determined according to...

Abstract

The invention belongs to the field of metal plastic processing, and in particular relates to a pressure straightening strategy method for a metal profile. The method first measures the geometric curve of the upper surface of the metal profile and obtains a series of data points, reads the data points, and obtains an overall straight line after calculation The straightness point to be straightened and the local straightness point to be straightened. After screening, the overall straightness point to be straightened data set and the local straightness to be straightened point data set are obtained; judge whether the data set is empty, if it is empty, end, otherwise Remove the points to be straightened that do not meet the requirements, and obtain the final data set of the points to be straightened for the metal profile. The method of the present invention makes full use of the inspection data of the full length of the profile, extracts and obtains its overall and local straightness information through a reasonable strategy method, and then accurately corrects the overall and local straightness at the same time after the one-time profile inspection is completed. Greatly improve the straightening effect, improve the straightening efficiency, and improve the yield.

Description

technical field [0001] The invention belongs to the field of metal plastic processing, and relates to a pressure straightening strategy method for metal profiles. Background technique [0002] Metal profiles are widely used structural materials in mechanical products. They are often used in the manufacture of important transmission parts such as guide rails and slide rails, and have extremely high requirements for straightness. However, the production and transportation process of metal profiles often cause them to be bent and deformed, resulting in their flatness not meeting the product quality requirements. Therefore, they need to be straightened to meet the flatness requirements of the parts. [0003] During the production and transportation process, bending deformation may be formed in the entire length of the profile and in the local area. Therefore, during the design and manufacture of parts, the overall straightness within the entire length of the profile and the loca...
