Embodiment Construction
[0009] The present invention will be described below with reference to the drawings in the embodiments of the present invention.
[0010] Such as Figure 2-Figure 3 As shown, the upsetting and extrusion forming method of the inner T-shaped ring blank of the present invention comprises the following steps:
[0011] 1) Process the inner T-shaped ring blank upsetting and extruding the molding die, heat the raw material steel ingot to 1180-1200°C, and then manufacture the lower sealing ring 1, the lower gasket 3, the outer mold cover 4, the mold core 5 and the The blank of the upper gasket 7;
[0012] 2) annealing the blanks of the lower sealing ring 1, the lower gasket 3, the outer mold casing 4, the mold core 5 and the upper gasket 7;
[0013] 3) Machining the lower sealing ring 1, the lower gasket 3, the outer mold sleeve 4, the mold core 5 and the upper gasket 7 to remove their excess;
[0014] 4) Quenching and tempering the lower sealing ring 1, the lower gasket 3, the out...

Abstract
The invention relates to a heading extruding and forming method for an internal T-shaped ring part blank. The heading extruding and forming method includes the following steps that a raw material steel ingot is heated, and then blanks of a lower sealing ring, a lower gasket, an outer die sleeve, a die core and an upper gasket are manufactured respectively through a forging technology; annealing is conducted on the blanks; machining is conducted on the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket, and the margins of the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket are removed; afterwards, quenching and tempering are conducted, so that the rigidity of the lower sealing ring, the lower gasket, the outer die sleeve, the die core and the upper gasket reaches the 35-40 Rockwell hardness number; afterwards, assembling is conducted; the lower sealing ring is put on a work platform, then the lower gasket is put in a clamping groove of the lower sealing ring, and under positioning and guiding of the lower gasket, the outer die sleeve and the die core are put on the lower sealing ring; then the forge piece blank is placed, and the upper gasket is put on the blank; and a hydraulic machine is started. According to the heading extruding and forming method, the forge piece blank can be promoted to be formed to become a component with an internal T-shaped structure, and a foundation is provided for final ring rolling of an inner T-shaped ring part.
Description
technical field [0001] The invention relates to an upsetting extrusion molding method for an inner T-shaped ring blank, which belongs to the technical field of forging. Background technique [0002] There is a SB564UNSN06690 nickel-based superalloy large-scale inner T-shaped ring, its structure is as follows figure 1 As shown, the inner T-shaped ring 10 includes an annular structure, on the inner wall of the annular structure is provided a circle of protrusions protruding radially, and the section of the protrusions is T-shaped. Due to the irregular shape, narrow material deformation temperature range, and high material deformation resistance, this kind of inner T-shaped ring is difficult to be directly ring-rolled. Therefore, it is necessary to preform the blank first, that is, to manufacture the inner T-shaped , and then use a ring rolling machine for ring rolling. However, no manufacturing method for preforming a blank has been developed in the prior art. Contents of ...
