Abstract
The invention relates to a device for performing heat treatment correction on a titanium alloy spoke structure welded case. According to the technical scheme, the device for performing heat treatment correction on the titanium alloy spoke structure welded case comprises a base, a central spindle, an inner cover, a limiting sleeve, a gland and a wedge block. The invention aims to perform heat treatment correction on the titanium alloy spoke structure welded case by utilizing the bulging force and gravity of the device, a supporting plate is limited to shrink to drive an inner case to move up during the heat treatment correction, and the titanium alloy spoke structure welded case is enabled to meet the requirement of design paper through one-step heat treatment correction.
Description
Technical field
The present invention relates to a kind of device, particularly relate to a kind of device for titanium alloy spoke structure welding casing straightening by heat treatment.
Background technology
Novel aircraft engine is pursue higher thrust-weight ratio, reduces the overall weight of engine, thus uses titanium alloy material in a large number, and wherein a lot of component is titanium alloy spoke structure welding casing.This kind of titanium alloy spoke structure welding casing is welded by interior casing, outer casing and several spoke-like support plates usually.Produce welding stress during welding and cause part deformation, need to heat-treat correction to titanium alloy spoke structure welding casing.When utilizing existing fixture straightening by heat treatment, cause interior casing moves because support plate shrinks, cause part defective, need to carry out secondary correction.
Summary of the invention
The object of this invention is to provide a kind of device for titanium alloy spoke structure welding casing straightening by heat treatment, the bulging power of this device and gravity (namely downward pressure) is utilized to heat-treat correction to titanium alloy spoke structure welding casing, during restriction straightening by heat treatment, support plate shrinks to drive on interior casing and moves, and makes titanium alloy spoke structure weld casing reach design paper requirement by a straightening by heat treatment.
Technical scheme of the present invention is: a kind of device for titanium alloy spoke structure welding casing straightening by heat treatment, described titanium alloy spoke structure welding casing comprises outer casing and interior casing, and described device comprises base, mandrel, inner cap, stop collar, gland, voussoir; Described mandrel is vertically set on described submounts and is fixedly connected on the center of described base; Described base arranges inner position seam and outside fix seam, and titanium alloy spoke structure welding casing is placed on described base, the described interior casing lower internal diameter in described inner position seam location, the described outer casing lower internal diameter in described outside fix seam location; Cover in described and be provided with positioning spigot one, described inner cap overlapped described mandrel and was placed on described interior casing, and described positioning spigot one locates described interior casing upper internal diameter, described stop collar was overlapped described mandrel be placed on described in cover; Described gland is provided with positioning spigot two, and described gland overlapped described mandrel and is pressed on described outer casing and is pressed on described stop collar simultaneously, and described positioning spigot two locates described outer casing upper internal diameter; Embed described voussoir between described mandrel and described gland, voussoir described in wedging makes described gland, compresses between described stop collar and described inner cap, described device installation.
In heat treatment process, by the bulging power of base, inner cap, gland, casing, outer casing up/down end internal diameter in titanium alloy spoke structure welding casing are corrected, and correct inside/outside casing right alignment.Simultaneously stop collar and gland are by the action of gravity that produces after voussoir wedging in interior casing upper end, in preventing from support plate from shrinking driving, casing moves, complete the distortion correction that titanium alloy spoke structure welds casing in titanium alloy spoke structure welding casing thermal histories.
Beneficial effect of the present invention: the problem of moving on interior casing when adopting this straightening by heat treatment device to solve titanium alloy spoke structure welding casing straightening by heat treatment, this device is simple to operate, economize on the use of funds, be easy to realize through engineering approaches application, the straightening by heat treatment requirement of titanium alloy spoke structure welding casing can be met.
Accompanying drawing explanation
Fig. 1 is the structural representation sectional view of titanium alloy spoke structure welding casing straightening by heat treatment device;
In figure: 1 is base, 2 is inner cap, and 3 is stop collar, and 4 is gland, and 5 is voussoir, and 6 is mandrel, and 7 is outer casing, and 8 is interior casing, and 9 is support plate.
Embodiment
As shown in Figure 1, be put on base 1 by titanium alloy spoke structure welding casing, press inner cap 2, load onto stop collar 3, then put gland 4, inserted wedge 5, completes Assembly of the parts.During straightening by heat treatment, the upper outside positioning spigot of base l and gland 4 produce bulging power external casing 7 upper and lower ends internal diameter under positioning spigot two high temperature correct, on base l, inner position seam and inner cap 2 positioning spigot one at high temperature produce bulging power internal casing 8 upper and lower ends internal diameter and correct, base 1, inner cap 2 are connected by mandrel 6 with gland 4 simultaneously, remain interior casing 8 and outer casing 7 right alignment in heat treatment process.Stop collar 3 applies gravity by the common internally casing 8 of gland 4 and voussoir 5, limit in straightening by heat treatment process because of support plate 9 heat shrinkable cause in casing 8 moves, complete titanium alloy spoke structure welding casing straightening by heat treatment.
