Heat setting tool for casting with complex structure

Abstract

The utility model discloses a heat setting tool for a casting of a complex structure. The heat setting tool comprises a positioning baffle A, wherein the positioning baffle A is provided with a positioning clamping block and conducts clamping face contact on a thin-wall clamping opening of the casting to restrain stress deformation. The casting is placed on the bottom plate, the thin-wall clamping opening obtains uniform supporting stress in the positioning clamping block through clamping face contact to restrain stress deformation, the situation that stress deformation occurs to the thin-wall clamping opening of the casting due to the fact that the stress of a local pressing point after supporting is large is avoided, and the problem that stress deformation occurs to the thin-wall clamping opening of the casting after supporting is conducted and the thin-wall clamping opening of the casting is pressed and contacted is solved.

Description

Technical Field

[0001] The utility model relates to a heat setting tool for castings with complex structures, belonging to the technical field of casting production tooling. Background Art

[0002] For thin-walled, complex-structured titanium alloy castings, defects in the castings need to be repaired by welding. After the repair welding, the castings are subjected to greater thermal stress and are prone to deformation due to heat.

[0003] The existing casting deformation prevention technology is shown in Chinese Patent Publication No. CN213142085U. Although deformation can be prevented by evenly distributing support and then pressing the casting, for castings with thin-walled clamps, stress deformation occurs at the thin-walled clamps of the castings after support and then pressing. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a heat setting tool for complex structure castings.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a heat setting tool for complex structure castings, comprising:

[0007] A positioning baffle A is provided to provide a positioning block for engaging the thin-walled clamping surface of the casting to suppress stress deformation.

[0008] It also includes a positioning baffle B, which is fixedly spaced from the positioning baffle A and distributed on the bottom plate to form a space for accommodating the casting; the positioning baffle A and the positioning baffle B are fixedly connected by a fixing block.

[0009] The positioning block at the positioning baffle A is integrally formed with the positioning baffle A and fixedly connected thereto.

[0010] The casting also includes a heat-setting support block A, a heat-setting support block B and a heat-setting support block C which can be placed in the concave space of the casting for surface contact support.

[0011] It also includes a counterweight block that can press down the heat-setting support block A, the heat-setting support block B and the heat-setting support block C. The counterweight block presses the heat-setting support block A, the heat-setting support block B and the heat-setting support block C flat on the top surface of the positioning baffle A and the positioning baffle B.

[0012] The beneficial effect of the utility model is that the casting is placed on the bottom plate, and the thin-walled clamp is contacted in the positioning block through the engaging surface to obtain uniform support force to suppress stress deformation, thereby avoiding the situation where the thin-walled clamp of the casting is subjected to excessive force after support and compression, which causes stress deformation at the thin-walled clamp of the casting, and solves the problem of stress deformation at the thin-walled clamp of the casting after support and compression.

[0017] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0018] like Figures 1 to 3 shown.

[0019] A heat setting tool for complex structure castings in the present application includes:

[0020] The positioning baffles A1 and the positioning baffles B4 are fixedly distributed on the bottom plate 8 at intervals, and the positioning baffles A1 and the positioning baffles B4 are fixedly connected by the fixing block 3. The relative inner surfaces of the positioning baffles A1 and the positioning baffles B4 are provided with positioning blocks 14 that are engaged with the thin-walled clamping opening 12 of the casting 2. The positioning block 14 at the positioning baffle B4 is integrally formed and fixedly connected with the positioning baffle B4, and the positioning block 14 at the positioning baffle A1 is integrally formed and fixedly connected with the positioning baffle A1.

[0021] It also includes heat setting support blocks A5, heat setting support blocks B6 and heat setting support blocks C7. Heat setting support blocks A5, heat setting support blocks B6 and heat setting support blocks C7 can be placed in the concave space of the casting 2 for surface contact support.

[0022] It also includes a counterweight block 9 that can press down the heat-setting support block A5, the heat-setting support block B6 and the heat-setting support block C7. The counterweight block 9 flattens the heat-setting support block A5, the heat-setting support block B6 and the heat-setting support block C7 on the top surface of the positioning baffle A1 and the positioning baffle B4 to prevent the heat-setting support block A5, the heat-setting support block B6 and the heat-setting support block C7 from being squeezed out when the concave space of the casting 2 rebounds.

[0023] The casting 2 is placed on the base plate 8, and the thin-walled clamp 12 on the side of the casting 2 contacts the engaging surfaces of the positioning blocks 14 on the positioning baffle A1 and the positioning baffle B4. The thin-walled clamp 12 obtains uniform support force in the positioning block 14 through the engaging surface contact to suppress stress deformation, thereby avoiding the situation where the thin-walled clamp of the casting is subjected to excessive force at the local point after support, which causes stress deformation, and solves the problem of stress deformation at the thin-walled clamp of the casting after support and compression.
