Description

Technical Field

[0001] The utility model relates to the technical field of flange post-weld correction, in particular to a multifunctional flange correction tool. Background Art

[0002] In the prior art, the commonly used method for angle correction between flange and pipe fitting is to adjust the position by directly clamping the flange with a fixture. Although this traditional correction method can achieve preliminary alignment of the angle to a certain extent, its inherent limitations cannot be ignored. First, directly clamping the flange for correction, especially when the clamping force is not properly controlled, can easily cause the flange to deform or be damaged. As a key component for connecting pipes and equipment, the shape accuracy and surface quality of the flange directly affect the sealing performance and service life. Once damaged, it often requires a complex repair process or even cannot be repaired, thereby increasing the risk of flange scrapping and causing unnecessary economic losses to the enterprise; secondly, even if some functions of the flange can be restored through repair, the time cost and labor cost of the entire processing process will increase significantly. Frequent repairs not only reduce production efficiency, but may also cause delays in production plans and affect the overall project progress. In addition, direct clamping correction is difficult to ensure the accuracy and consistency of correction, because the instability of human operation and the accuracy limitations of the fixture itself may affect the correction results.

[0003] In summary, the traditional clamping flange correction method has obvious drawbacks, and there is an urgent need for a more efficient, accurate and less damaging multifunctional flange correction tooling to meet the needs of modern industrial production. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a multifunctional flange correction tool, which performs correction by matching a frustum with a flange mounting hole, thereby avoiding deformation or surface damage that may be caused by directly clamping the flange.

[0005] The technical solution of the utility model is as follows:

[0006] A multifunctional flange correction tool comprises a base, a sliding block and a truncated cone, wherein the truncated cone is fixedly arranged on the top of the sliding block, and the sliding block can be installed on the base in a horizontal linear sliding manner.

[0007] The base is provided with a groove body which cooperates with the sliding block in a horizontal direction, and the groove body penetrates the base horizontally.

[0008] The groove body is a T-shaped groove, and the sliding block is a T-shaped block structure that is clearance-matched with the groove body.

[0009] The matching clearance between the slider and the trough body is 0.05-0.1mm.

[0010] Two sliding blocks are installed in the tank body.

[0011] The length and width dimensions of the base match the dimensions of the flange to be calibrated.

[0012] The outer diameter and height dimensions of the frustum match the dimensions of the flange mounting hole of the flange to be calibrated.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model discloses a multifunctional flange correction tool, which reduces the risk of flange damage: the tool performs correction by matching the truncated cone with the flange mounting hole, avoiding deformation or surface damage that may be caused by directly clamping the flange. This non-contact or slight contact correction method can significantly reduce the risk of flange damage, protect the original accuracy and surface quality of the flange, and reduce the economic losses caused by flange scrapping.

[0015] 2. The utility model discloses a multifunctional flange correction tool, which improves the correction accuracy and consistency: through the precisely designed frustum and the matching mechanism of the slider and the slot body, the tool can achieve fine adjustment of the flange angle. Compared with traditional manual operation, this mechanized correction method has higher stability and repeatability, can significantly improve the correction accuracy and consistency, and ensure that each flange can achieve the expected correction effect.

[0022] The components represented by the reference numerals in the figure are:

[0023] The utility model comprises: 1. a base, 2. a sliding block, 3. a frustum, 4. a trough body, 5. a flange, and 6. a pipe fitting. DETAILED DESCRIPTION

[0024] like Figure 1 As shown, the multifunctional flange correction tool integrates three core components: a base 1, a slider 2 and a frustum 3, aiming to provide an efficient and accurate flange correction solution.

[0025] Among them, Figure 2 As shown, the truncated cone 3 is firmly mounted on the top of the slider 2 by welding or the like, and the slider 2 can slide flexibly and linearly in a horizontal direction on the base 1.

[0026] The base 1 is specially designed with a slot body 4 that fits tightly with the slider 2. The slot body not only runs through the entire base horizontally, but also adopts a T-slot structure to ensure accurate and stable clearance fit with the T-block-shaped slider 2. This clearance is carefully controlled between 0.05-0.1mm to balance smooth sliding and correction accuracy. In order to further improve the correction efficiency and flexibility, two sliders 2 are cleverly installed in the slot body 4.

[0027] It is worth noting that the size of the base 1 is carefully customized to ensure that it matches the length and width of the flange 5 to be corrected, so as to achieve precise docking. The outer diameter and height of the truncated cone 3 are strictly designed according to the size of the flange mounting hole to ensure that it can accurately and stably act on the flange during the correction process, achieving an efficient and lossless correction effect.

[0028] The multifunctional flange correction tool can meet the angle requirements between the flange and the connecting piece through the base and the conical slider. This avoids the unqualified angle between the flange mounting hole and the connecting piece after welding due to the lack of correction tool. It improves the correction efficiency and reduces the scrap rate.

[0029] In a specific embodiment: the length and width of the base 1 can be of any size, the slider 2 slides in the groove of the base, and the distance between the sliders can be adjusted arbitrarily; the slider 2 can be of any size, and can adapt to flange correction of different sizes by cooperating with the groove body 4; the cone 3 can be of any diameter, and can adapt to the size of the flange mounting hole by adjusting the size of the upper and lower diameters of the cone; the clearance between the groove body 4 on the base 1 and the slider 2 is matched, and the tolerance is 0.05-0.1mm.

[0030] like Figure 3 and Figure 4 As shown, the base 1 and the flange 5 to be calibrated are fixed by the frustum 3. The base 1 is clamped with a vise, and the upper part connected to the flange is rotated by a wrench to achieve Figure 3to complete the correction of the 6-angle between the flange and the pipe fitting.

[0031] By using this multifunctional flange correction tool, after the flange 5 is welded, while it is corrected to the angle required by the drawing, it also avoids the scrapping of the flange 5 caused by abnormal correction, thereby improving the quality and qualification rate.
