Embodiment Construction

[0029] The present invention is described in detail below with reference to accompanying drawing and embodiment:

[0030] attached Figures 1 to 6 It can be seen that a method for processing an extra-large arc plate comprises the following steps:

[0031] A, making tire board;

[0032] B. Process the bottom surface of the sheet to be processed into a plane;

[0033] C. Weld the tire plate and the bottom surface of the sheet;

[0034] D. Fit the tire plate to the surface of the machine table;

[0035] E. Detect the radian of the upper arc surface formed by the bottom surface of the sheet; the upper arc surface and the arc surface of the finished arc plate form a conjugate surface;

[0036] F. Carry out milling processing on the upper plane of the sheet metal; ensure that the height difference of the arc plate meets the requirements of the processing drawings;

[0037] G. Remove the tire board; separate the tire board from the machine table and then separate the tire board ...

Abstract

A method for machining extra large circular arc plates comprises the following steps that a bed mould is manufactured, the bottom face of a plate needing to be machined is machined into a plane, the bed mould is welded to the bottom face of the plate, the bed mould is attached to the surface of a machine tool table, the radian of an upper circular arc face formed at the bottom face of the plate is detected, the upper circular arc face and an arc face of a finished circular arc plate form a conjugate surface, milling is conducted on the upper plane of the plate, the difference of a high point and a low point meets the demand of a pattern, the bed mould is dismantled, and the bed mould is separated from the circular arc plate after the bed mould is separated from the machine tool table. The method for machining and preparing the extra large circular arc plates is simple in machining device and high in machining accuracy, lowers machining difficulty, and saves machining time and machining cost.

Description

technical field [0001] The invention relates to a processing method of a plate, in particular to a processing method of an extra-large arc plate. Background technique [0002] In some special equipment, it will be applied to the arc plate with a large radius, and the thickness of the arc plate will have very strict dimensional accuracy requirements. In the first largest single-cylinder 400MN die forging hydraulic press in China, a circular arc plate was 12.81 meters in length, 2.3 meters in width, and 317.576 meters in radius. It is difficult to grasp the dimensional accuracy of such a large radius and the ultra-thin thickness at both ends of the arc plate. It is impossible to complete the processing with a radius of 317.56 meters and the thinnest dimension at both ends of 0.2mm by conventional CNC machine tools. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a processing method for extra-lar...
