Vertical rib plate machining method

Abstract

The invention discloses a vertical rib plate machining method. The vertical rib plate machining method comprises the steps that S1, a blank material is prepared; S2, the blank material is laterally pressed by the four sides, a big allowance is removed through rough machining, and the allowance of 4mm remains in the single side, and a roughing part is obtained; the roughing part is subjected to semi-finishing, the allowance of 2mm remains in the single side, and a semi-finishing part is obtained; S3, first annealing treatment is conducted, heating is conducted to reach the temperature of 220-260 DEG C, heat preservation is conducted for 3-3.5 hours, and air cooling is conducted; S4, the semi-finishing part is clamped in an overturning mode, the bottom face of the semi-finishing part is machined, and it is guaranteed that the flatness of the bottom face is not larger than 0.1 mm; and S5, secondary annealing treatment is conducted, heating is conducted to reach the temperature of 200-220DEG C, heat preservation is conducted for 3-3.5 hours, and air cooling is conducted. When the vertical rib plate machining method is adopted, clamping is convenient, the clamping times are fewer, themachining process datum is unified, errors of repeated positioning are effectively reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a method for processing vertical ribs. Background technique [0002] Ribs have the characteristics of light weight, high bearing capacity, strong bending resistance, and small space occupation. After reasonable design, they can play the role of support, protection, and frame connection. They are widely used in aerospace, ships, automobiles, construction, and energy transportation. and other fields. Effective reinforcement optimization can not only rationally organize the structure, make full use of space, and tap the potential of materials, but also reduce product costs and reduce the negative effects caused by the increase in unit capacity. When the rib plate is welded, it will produce large thermal stress, which will lead to deformation of the parts, which will affect the installation accuracy of the rib plate and affect the processing quality; and then there wil...

AI Technical Summary

Problems solved by technology

When the rib plate is welded, it will produce large thermal stress, which will lead to deformation of the parts, which will affect the installation accuracy of the rib plate and affect the processing quality; and then there will be a large error in the installation accuracy, and the installed rib plate will be damaged. There is internal stress, which leads to cracking and damage of the ribs, which seriously affects the service life of the ribs

Moreover, welding can also cause environmental pollution, which is not in line with today's energy-saving and environmentally friendly production concepts.
