Description

Technical Field

[0001] The utility model relates to the technical field of coil press-fitting, in particular to a supporting device and a pressing device for coil press-fitting, which are used for press-fitting a coil of an electric transformer. Background Art

[0002] The rectangular coil of the distribution transformer is formed by winding the wire around a winding mold. In order to ensure that the size of the coil after winding meets the requirements, the rectangular coil of the distribution transformer needs to be pre-pressed with a pressing device after winding. After pre-pressing, it needs to be put into the drying room for drying and shaping.

[0003] When the coil is placed in the pressing device for pre-pressing, a supporting device needs to be placed inside the inner coil. The supporting device needs to have great strength and be able to withstand the pre-pressure for a certain period of time without deformation.

[0004] The traditional support device is made of solid steel blocks. Although it has good strength, it is very heavy and inconvenient for personnel to operate. Specifically, because the tooling is too heavy, it cannot be lifted by one person, and two people are required to lift it, which not only reduces work efficiency, but also reduces the safety of operation, and there is a risk of hitting feet. Utility Model Content

[0005] In view of the defects mentioned in the background technology, the utility model proposes a novel supporting device and a pressing device to achieve the advantage of the supporting device being lightweight while having sufficient strength.

[0006] Based on this, the purpose of the present invention is to provide a support device for coil press-fitting to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a support device for coil pressing, which includes a three-dimensional structure for being placed in the coil to support the coil. The shape of the three-dimensional structure can be set according to the requirements of the coil, for example, it can be a rectangular structure, or it can be a cube structure, etc.

[0008] Preferably, a cavity is formed in the three-dimensional structure, that is, the three-dimensional structure is different from the solid supporting device in the traditional technology. The supporting device is hollow, which can significantly reduce the weight of the supporting device and achieve a lightweight effect.

[0009] Preferably, the wall surface of the three-dimensional structure is made of a plate, which may be a metal plate with relatively high strength such as a steel plate or an iron plate.

[0010] Preferably, a support body for strengthening the three-dimensional structure is provided in the cavity. In order to prevent the support device from being deformed under the action of the pressing device, the support body is arranged in the cavity to ensure the strength of the support structure.

[0011] Preferably, the three-dimensional structure is a cube, which includes an upper plate, a lower plate, and a side plate connecting the upper plate and the lower plate, that is, the appearance is basically consistent with that of a traditional solid steel block.

[0012] Preferably, the support body includes a support plate, which is placed in the cube and has its two ends respectively connected to the upper plate and the lower plate. In actual use, the upper plate and the lower plate occupy a larger area and are subjected to more pressure, so the stress of the upper plate and the lower plate needs to be dispersed. Therefore, the support plate is also connected between the upper plate and the lower plate to share the stress and prevent the upper plate and the lower plate from deformation.

[0013] Preferably, there are several support plates evenly distributed in the cavity, so that the stress borne by the upper plate and the lower plate is evenly dispersed.

[0014] Preferably, the support body also includes a reinforcing plate, which forms a corner at the connection between the support plate and the upper plate and the lower plate, and the reinforcing plate is connected to the corner, that is, the connection strength between the support plate and the upper plate and the lower plate is strengthened to prevent stress from concentrating at the connection and causing deformation of the support body.

[0015] Preferably, there are several reinforcing plates, which can be distributed on each supporting plate to enhance the connection strength of each supporting plate.

[0016] In order to solve the above technical problems, the utility model also provides the following technical solutions: a pressing device for coil pressing, which includes the aforementioned supporting device for coil pressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment: This embodiment provides the best implementation scheme of the support device for coil press-fitting, which is used in the clamping equipment for coil press-fitting.

[0026] Specifically, the supporting device includes a three-dimensional structure that is placed in the coil to support the coil; in this embodiment, the supporting device is used in the press-fitting of the distribution transformer coil. In order to match the shape of the distribution transformer coil, the cross-section of the three-dimensional structure is a rectangle, and extends at both ends of the rectangle to form a cuboid.

[0027] In this embodiment, if Figures 1-2 A cavity 3 is formed in the three-dimensional structure, that is, the interior of the rectangular parallelepiped is hollow.

[0028] In this embodiment, if Figures 1-2 The wall of the three-dimensional structure is prepared by a plate 1, which is a steel plate, and specifically includes an upper plate 11 and a lower plate 12, and a side plate 13 connecting the upper plate 11 and the lower plate 12. There are two side plates 13, which are welded on both sides of the upper plate 11 and the lower plate 12 to form a cylindrical structure with openings at both ends, that is, the two ends of the three-dimensional structure do not need to be closed by plates and are in an open state.

[0029] In this embodiment, if Figures 1-2 The support body includes a support plate 21, which is placed in the rectangular parallelepiped and has two ends welded to the upper plate 11 and the lower plate 12 respectively;

[0030] Specifically, Figure 1 , the extension direction of the upper plate 11 is the X-axis, on the plane where the upper plate 11 is located, the direction perpendicular to the X-axis is the Y-axis, and the direction perpendicular to the lower plate 12 is the Z-axis, then the support plate 21 is located in the plane where the X-axis and the Z-axis are located, and extends along the X-axis, so that the stress is dispersed for the upper plate 11 and the lower plate 12 in the entire extension direction of the three-dimensional structure.

[0031] In this embodiment, if Figures 1-2 There are three support plates 21, which are evenly distributed in the cavity 3 along the Y-axis direction and are welded to the upper plate 11 and the lower plate 12, dividing the cavity 3 into four parts.

[0032] In this embodiment, if Figures 1-2The support body further includes a reinforcing plate 22, the support plate 21 forms a corner with the connection between the upper plate 11 and the lower plate 12, and the reinforcing plate 22 is connected to the corner;

[0033] Specifically, Figures 1-2 The reinforcing plates 22 are right-angled triangular plates, which are welded at the corners formed by the connection between the support plate 21 and the upper plate 11 and the lower plate 12, and there are 16 triangular plates, which are evenly divided into two groups and distributed at the two open ends of the three-dimensional structure, and two reinforcing plates 22 are welded at each end of the four cavities 3.

[0034] Comparing the coil pressing support device in the embodiment with the traditional solid tooling of the same size, it is found that the weight of the improved support device is only 1 / 10 of the traditional one, and it can be fully operated by one person, which not only improves work efficiency but also reduces safety risks during operation.
