Thick-wall 800H alloy machining equipment and machining method thereof

Abstract

The invention discloses thick-wall 800H alloy machining equipment and a machining method thereof. The method comprises the following steps that the two ends of an annular-column-shaped thick-wall 800Halloy piece are placed on clamping equipment, a rod piece with an outer thread opening in the outer wall is rotated manually, the rod piece with the outer thread opening in the outer wall drags a supporting head to move, the supporting head drags a plate-shaped part used for firm clamping to firmly clamp and reinforce the inner wall of the annular-column-shaped thick-wall 800H alloy piece; and apiston is operated and drags a connecting block to move. The problems that in the prior art, a prepared annular-column-shaped thick-wall 800H alloy piece rebounds, when the annular-column-shaped thick-wall 800H alloy piece is clamped, concave spots are often generated on the clamped wall face of the annular-column-shaped thick-wall 800H alloy piece, the wall face of the annular-column-shaped thick-wall 800H alloy piece is uneven, and the defect that the annular-column-shaped thick-wall 800H alloy piece is brittle due to too large impact are solved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of thick-walled 800H alloy processing, in particular to a thick-walled 800H alloy processing equipment and a processing method thereof. Background technique [0002] INCOLOY800H is an austenitic heat-resistant alloy widely used in high-temperature pressure-bearing structural parts. The high strength of 800H is mainly due to the addition of carbon, aluminum, and titanium elements, and it is annealed at a minimum temperature of 1149 ° C to achieve a grain size of ASTM5 Grade or coarser. The thick-walled alloy corresponding to INCOLOY800H material, that is, the biggest advantage of the thick-walled 800H alloy is that it can be 100% recycled, which is in line with the national strategy of environmental protection, energy saving, and resource conservation. The national policy encourages the expansion of the application field of the thick-walled 800H alloy. [0003] The method of folding...

Problems solved by technology

[0005] The current device is unable to reduce the amount of deformation of the ring-column-shaped thick-walled 800H alloy part after the roll forming is completed, which makes the ring-column-shaped thick-walled 800H alloy part rebound after the preparation is completed; the current device When clamping the ring-shaped thick-walled 800H alloy parts, concave spots often appear on the clamped wall surface of the ring-shaped thick-walled 800H alloy parts, which makes the wall surface of the ring-shaped thick-walled 800H alloy parts uneven. When the folding preparation is started, the clamping position does not have shock absorption performance, and it often happens that the ring-shaped thick-walled 800H alloy parts are brittle due to too much impact, making the folding preparation unsuccessful
