Embodiment Construction

[0029] The following examples describe the present invention in detail. These examples are only to describe the best embodiment of the present invention, and do not limit the scope of the present invention.

[0030] 180° arch beam structure diagram of 400MN die forging hydraulic press, from Figure 1 It can be seen from the above that it is composed of three 40° single beams and two 30° single beams connected by positioning pins. Including 30° left arch beam 1, 40° left arch beam 2, 40° middle arch beam 3, 40° right arch beam 4, 30° right arch beam 5, positioning pin 6. Such as figure 1 shown.

[0031] A mechanical processing method for a combined 180° arch beam. The mating surfaces of a single arch beam are processed well, and allowances are left for other parts, and the mating surfaces are ground and combined to form a 180° arch beam. Part finishing benchmark, split 180° arch beam, and finish processing each single arch beam; take 40° middle arch beam as an example to il...

Abstract

The invention relates to a machining method of a combined 180-degree arch beam. The machining method comprises the steps that the matching faces of all arch beam single bodies are machined, allowancefor other parts is reserved, the matching faces are subjected to lapping-fitting, the contact rate is 80%, 0.10 mm of a feeler gauge cannot enter the space, and the 180-degree arch beam is assembled on a numerical control milling machine; the180-degree plane of the combined arch beam and positioning pin holes in the 180-degree plane are subjected to finish machining overall, the inner arc surface,outer arc surface and upper plane datum are made; the 180-degree arch beam is disassembled; and all the arch beam single bodies are subjected to finish machining according to the datum in the step 6.The combined 180-degree arch beam is machined through the machining method, thus the machining precision is improved, all technical indexes are controlled within the minimum range, and the technicalrequirements of a drawing are met.

Description

technical field [0001] The invention relates to the field of machining, in particular to a machining method for a combined 180° arch beam. Background technique [0002] The 400MN heavy-duty aviation precision die forging hydraulic press is designed by Tsinghua University according to the Kanhe principle, and it is the largest steel wire winding single frame, single cylinder die forging hydraulic press in the world so far. The 180° arch beam of the machine is composed of three 40° single beams and two 30° single beams. The usual processing method for 180° arch beams is to combine the 5 split bodies that make up the 180° arch beams according to the figure, and then combine the 5 split bodies to form a 180° arch beam. The 180° arch beam formed by this processing method is difficult to meet the design technical requirements in terms of size and shape tolerance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mech...
