Problems solved by technology

Due to the large amount of heat input during welding, the welding stress is huge, resulting in serious welding deformation, and the roundness of both ends of the final dimension of the part (design value 1.5mm) is out of tolerance
[0004] If the roundness of the end face of the shell is out of tolerance, the subsequent shells will not be able to be assembled and riveted, and eventually the shell will be scrapped, which will cause incalculable economic losses and consume a lot of manpower and time costs

Embodiment 1

[0022] Such as figure 1 As shown, a shell product end face roundness vibration aging correction device, it includes a strut 1, an adjustment mechanism 2, a pressure block 3, a vibrator 5, a probe 6 and a measuring device 7, the two ends of the strut 1 are respectively There are briquetting blocks 3, and an adjusting mechanism 2 is arranged between each briquetting block 3 and the strut 1. The briquetting block 3 moves along the axial direction of the strut 1 under the regulation of the regulating mechanism 2, and the outer surface of the briquetting block 3 pushes Press on the inner wall of the housing 4 to be adjusted, the exciter 5 is placed on the inner wall of the housing 4 to be adjusted, the probe 6 is arranged on the outer wall of the housing 4 to be adjusted near the pressing block 3, and the measuring device 7 is respectively It is connected with probe 6 and vibrator 5 for control.

[0023] The pressing block 3 presses against the smallest diameter of the housing 4 t...

Embodiment 2

[0033] The structure of a device for correcting the roundness of the end face of a shell product through vibration and aging is the same as that in Embodiment 1.

[0034] A method for correcting the shape of a shell product end face roundness vibration aging correction device is adopted, which comprises the following steps:

[0035] S1, measure the diameter of the housing 4 to be corrected: measure the diameter of the housing 4 to be corrected with a diameter measuring tool, and mark its minimum diameter position;

[0036] S2. Install the correcting device: put the correcting device into the housing 4 to be corrected, adjust the adjusting mechanism 2, and press the pressing blocks 3 against the minimum diameter of the housing 4 to be corrected;

[0037] S3, afterburner support large end frame: such as figure 2 As shown, adjust the regulating mechanism 2, so that the end face diameter of the housing 4 to be corrected is enlarged by 7.5mm;

[0038] S4, vibration aging: start ...

Embodiment 3

[0042] The structure of a device for correcting the roundness of the end face of a shell product through vibration and aging is the same as that in Embodiment 1.

[0043] A method for correcting the shape of a shell product end face roundness vibration aging correction device is adopted, which comprises the following steps:

[0044] S1, measure the diameter of the housing 4 to be corrected: measure the diameter of the housing 4 to be corrected with a diameter measuring tool, and mark its minimum diameter position;

[0045] S2. Install the correcting device: put the correcting device into the housing 4 to be corrected, adjust the adjusting mechanism 2, and press the pressing blocks 3 against the minimum diameter of the housing 4 to be corrected;

[0046] S3, afterburner support large end frame: such as figure 2 As shown, adjust the adjustment mechanism 2 to make the end face diameter of the housing 4 to be corrected enlarged by 7.8mm;

[0047] S4, vibration aging: start the ...

Abstract

The invention relates to a shell product end surface roundness vibration aging shape-correction device. The device comprises a brace rod (1), press blocks (3), a vibration exciter (5), a probe (6) and a measurement device (7), wherein two ends of the brace rod (1) are respectively provided with the press block (3), the press block (3) is pressed on the inner wall of a to-be-shape-corrected shell (4), the vibration exciter (5) is arranged on the inner wall of the to-be-shape-corrected shell (4), and the probe (6) is arranged on the outer wall of the to-be-shape-corrected shell (4) close to the press block (3). The shape-correction method comprises the following steps: S1, measuring diameter of the to-be-shape-corrected shell (4); S2, mounting the shape-correction device; S3, stretching the end frame by adding force; S4, carrying out vibration ageing; S5, standing; and S6, detecting. The device and method disclosed by the invention have the advantages that the problem that the end surface roundness of the welded and machined shell product is poor is effectively solved, the final appearance size of each section is guaranteed, the pass rate of the shell and the section is obviously prompted, and the shell production and problem processing periods are shortened.

Description

technical field [0001] The invention relates to a device for correcting the roundness of the end face of a shell product through vibration and aging and a method for correcting the shape. Background technique [0002] The deformation problem of high-strength steel cylindrical thin-walled welded structure has always been the focus and difficulty in the manufacture of shells. In order to ensure its manufacturing accuracy, it is usually necessary to control welding deformation and adopt post-weld correction. The main way to control welding deformation is to use special fixtures to fix the welding parts "inner support and outer hugging" before welding. However, due to excessive welding stress, the anti-deformation effect is not ideal, and there is still a phenomenon of out-of-poor roundness. [0003] The material of a shell product is 2A14, the diameter is 2000mm, the height is 505mm, and the wall thickness is 14mm. The shell is assembled and welded by the upper shell section an...
