Embodiment Construction
[0016] The structure of the heat-shaping jig for titanium alloy thin-walled tubular parts of the present invention will be further described below through examples and in conjunction with the accompanying drawings.
[0017] The thermal correction fixture in this embodiment is used for the high-pressure compressor front case on the engine. The material of the high-pressure compressor front case is titanium alloy TC2, mainly by butt welding of 2 forgings, 2 semi-cylindrical bodies and It is formed by surfacing welding of 4 longitudinal mounting sides and rolling welding of 2 annular reinforcing ribs, with a wall thickness of 1.5mm-3.3mm and a height of 530mm.
[0018] In this embodiment, the structure of the thermal correction clip is as follows figure 1 , figure 2 As shown, it includes a base 1 , a shape adjustment seat 2 , a shape adjustment screw 3 , a support seat 5 , a bushing 11 and a pressure plate 7 . The shape-correcting seat 2 is a cylindrical body with a flange, an...

Disclosed is a thermal shaping clamp of a titanium alloy thin-wall tubular part. The thermal shaping clamp of a titanium alloy thin-wall tubular part comprises a base, a shaping seat, shaping screws, a support seat, bushes and press boards. The shaping seat is a cylinder with a flange disc, and the wall of the cylinder is provided with at least two circles of bush mounting holes around the central line of the cylinder; the support seat is in a ring shape; the central hole of every bush is a screw hole matched with the corresponding shaping screw, and the bushes and the shaping screws are identical to the bush mounting holes in the cylinder of the shaping seat in quantity; the shaping seat is mounted onto the base through the flange disc, the support seat is mounted on the base, and the central line of the support seat coincides with that of the shaping seat; every bush is mounted inside the corresponding bush mounting hole in the cylinder of the shaping seat, and every shaping screw is mounted inside the screw hole of the corresponding bush; the number of the press boards is at least four, and the press boards are mounted on the circumference of the base at equal intervals and used for fixing the portions of a titanium alloy thin-wall tubular part to be shaped on the upper end surface of the support seat after the titanium alloy thin-wall tubular part to be shaped is mounted in position.
Description
technical field [0001] The invention belongs to a shape correcting fixture for thin-walled parts, in particular to a thermal shape correcting fixture for titanium alloy thin-walled cylindrical parts. Background technique [0002] Titanium alloy is a material with good thermoplasticity and is easy to deform when heated. Therefore, thin-walled cylindrical parts made of such materials are prone to deformation during welding and heat treatment, especially thin-walled cylindrical parts with complex shapes (such as on engines The high-pressure compressor front casing), the deformation is more serious, in order to make the thin-walled cylindrical parts made of titanium alloy meet the design requirements, the shape must be corrected after welding, and the shape correction fixture must be used during heat treatment. The existing heat-calibration jig has a complex structure and poor versatility, and it is difficult to meet the requirements of heat-calibration of titanium alloy thin-wa...
