Embodiment Construction

[0056] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0057] A processing method of a combined moving beam according to the present invention, such as Figure 1a-Figure 1e As shown, the combined moving beam is formed by connecting four identical single beams 1 through positioning pins 2, as shown in Figure 2a-Figure 2c As shown, each single beam 1 includes a side plate 11, a side plate 2 12 and a 1 / 4 cylinder 13 between the side plate 1 and the side plate 2, and the section of the 1 / 4 cylinder 13 corresponds to The cross-sections of side plate one 11 or side plate two 12 are in the same plane; the cross-section of 1 / 4 cylinder 13 is the joint surface of each single beam 1, and positioning pin holes 5 are correspondingly opened on it; The processing method of the combined moving beam comprises the following steps:

[0058] 1) Platform marking:

[0059] (1) Place the single beam 1 on the platform, ...

Abstract

The invention relates to a machining method for a combined moving beam. The combined moving beam is formed by connecting four identical one-piece beams through positioning pins. Each one-piece beam comprises a first side plate, a second side plate and a demisemi cylinder located between the first side plate and the second side plate; the cross section of each demisemi cylinder and the cross section of the first side plate on the corresponding side or the cross section of the second side plate on the corresponding side are in the same plane; and the cross sections of the demisemi cylinders arejoint faces of the one-piece beams and provided with positioning pin holes in a one-to-one-correspondence mode. The machining method for the combined moving beam comprises the steps of platform scribing, rough machining, flaw detection, residual stress relieving, semifinishing, assembling, finishing and the like. By reasonably formulating the process route, all technical indexes are controlled inthe minimum range, and thus the technical requirements of drawings are met.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a combined moving beam used in a heavy-duty aviation precision forging hydraulic press. Background technique [0002] The 400MN heavy-duty aviation precision die forging hydraulic press was designed by Tsinghua University according to the Kanhe principle. It is by far the largest single-frame, single-cylinder steel wire winding hydraulic die forging hydraulic press in the world. The moving beam of this equipment is composed of four single beams. In order to ensure the overall precision of the combination, the processing accuracy is very high, and there is no processing precedent for the moving beam of this structure in China. Contents of the invention [0003] The invention provides a processing method of a combined moving beam, through rationally formulating a process route, all technical indicators are controlled within the minimum range,...
