Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of iron core clamps, and in particular to a clamping structure for an angled iron core. Background Technology
[0002] Angle-folded cores are a type of wound core, composed of multiple closed, bent silicon steel sheets stacked together. Their final shape is not achieved through annealing, but rather through bending the silicon steel sheets, thus eliminating the reliance on annealing. Therefore, some transformers use angle-folded cores instead of traditional wound cores.
[0003] In the production process of angle-core transformers, transformer assembly and core production are mostly completed in different workshops. Generally, after the core is produced, it is transported to the transformer assembly workshop for assembly with the coils.
[0004] During the transportation of angled iron cores, securing and protecting the cores is crucial. Currently, there is no fixed method for packaging and transporting angled iron cores; most often, the cores are laid flat in combination with simple wooden frames. This method does not provide sufficient protection for the cores, and the simple packaging is discarded after the cores are replaced with proper clamps. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a clamping structure for a bent iron core to solve one or more problems in the prior art.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A clamping structure for a bent iron core includes a top plate, a bottom plate, and two side plates. The top plate and the bottom plate are arranged in parallel, and the two side plates are respectively connected between the top plate and the bottom plate. The top plate, the bottom plate, and the side plates form a cavity for accommodating the bent iron core. The sides of the top plate, the bottom plate, and the side plates facing the cavity are all provided with baffles to prevent the bent iron core from leaving the cavity.
[0008] With the above solution, the iron core is placed in the cavity of the clamp before transportation. The clamp's fully enclosed structure can effectively protect every edge of the iron core, reducing the risk of damage during transportation and effectively protecting the iron core. Moreover, the clamp structure can not only be used for transporting folded iron cores, but also for clamping iron cores and directly using them for transformer assembly, replacing the disposable packaging solution and reducing production costs.
[0009] Furthermore, the side plate and the bottom plate are an integral structure, and the top plate is detachably connected to the two side plates.
[0010] Furthermore, each end of the top plate extends into an extension section along the length direction, and a connecting section is provided on the extension section. The connecting section is parallel to the side plate, and the width of the extension section is less than the width of the side plate. The end of the extension section away from the top plate is located between the two flanges of the side plate, and the corresponding connecting section is fixed to the side of the side plate facing the chamber by bolts.
[0011] With the above solution, the top plate can be detachably connected to the side plate, and when the top plate is disassembled and reinstalled on the side plate, it can slide vertically from the top of the side plate down along the edge of the side plate to the installation position, which can complete the positioning more quickly and make the installation process faster.
[0012] Furthermore, the connecting section is located on the side of the top plate away from the chamber.
[0013] The above solutions facilitate the clamping and fixing of bolts, making the loading and unloading process more convenient.
[0014] Furthermore, a waist-shaped hole is provided on the side plate, and the waist-shaped hole is located on the side of the top plate away from the cavity.
[0015] The above solutions provide bolt mounting holes for fixing to the external structure, making the clamp structure more stable when fixed to the external structure.
[0016] Furthermore, there are multiple waist-shaped holes on the same side plate, and these multiple waist-shaped holes are arranged at intervals along the width direction of the corresponding side plate.
[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows: Before transporting the iron core, the iron core is placed in the cavity of the clamp. The full-enclosure structure of the clamp can effectively protect every edge of the iron core, reduce the risk of damage during transportation, and effectively protect the iron core. Moreover, the clamp structure can not only be used for transporting folded iron cores, but also for clamping the iron core and directly using it for transformer assembly, replacing the disposable packaging solution and reducing production costs.

[0025] A clamping structure for a bent iron core, see [link / reference]. Figure 1 The system includes a top plate 1, a bottom plate 3, and two side plates 2. The two side plates 2 are integrally formed with the bottom plate 3 and are located on opposite sides of the bottom plate 3. The side plates 2 are perpendicular to the bottom plate 3. The top plate 1 is parallel to the bottom plate 3, and its two ends are detachably connected to the ends of the two side plates 2 furthest from the bottom plate 3. The top plate 1, bottom plate 3, and side plates 2 form a chamber 4 for accommodating the angled iron core. The sides of the top plate 1, bottom plate 3, and side plates 2 facing the chamber 4 are all provided with baffles to prevent the angled iron core from detaching from the chamber 4.
[0026] See Figure 2 The side plate 2 and the bottom plate 3 are made by laser cutting metal sheets and then using an integral bending process. The height of the side plate 2 is higher than the height of the corner iron core it accommodates. The side plate 2 has a lower clamping bolt hole 22 and a waist-shaped hole 21 at the position where it is higher than the corner iron core.
[0027] There are two lower clamping bolt holes 22, which are located near the two sides of the side plate 2. The waist-shaped hole 21 is located on the side of the lower clamping bolt holes 22 away from the bottom plate 3. The length of the waist-shaped hole 21 is parallel to the length of the side plate 2.
[0028] In one embodiment, see Figure 3 The length direction of the waist-shaped hole 21 is perpendicular to the length direction of the side plate 2.
[0029] In one embodiment, see Figure 4 There are multiple waist-shaped holes 21 on the same side plate 2, and the multiple waist-shaped holes 21 are arranged at intervals along the width direction of the corresponding side plate 2.
[0030] See Figure 1 , Figure 5Both ends of the top plate 1 extend into extension sections 11 along the length direction. Connecting sections 12 are provided on the extension sections 11, and are parallel to the side plates 2. Like the side flanges, the connecting sections 12 are formed by bending the top plate 1, but the bending direction of the connecting sections 12 is opposite to that of the side flanges on the top plate 1. The width of the extension sections 11 is less than the width of the side plates 2. The extension sections 11 have the same number of upper clamping bolt holes 13 as the lower clamping bolt holes 22 on the side plates 2. When the top plate 1 is connected to the side plates 2, the end of the extension section 11 furthest from the top plate 1 is located between the two side flanges of the side plates 2, and the upper clamping bolt holes 13 on the connecting sections 12 correspond one-to-one with the corresponding lower clamping bolt holes 22 on the side plates 2, and the corresponding upper clamping bolt holes 13 and lower clamping bolt holes 22 are connected together.
[0031] Preparations before transportation: Place and fix the base plate 3 horizontally, with the side plate 2 facing vertically upwards. Place the cut-to-shape clamping insulation inside the lower clamping frame formed by the base plate 3 and side plate 2. Then place the angled iron core into the U-shaped frame of the lower clamping. Place the upper clamping insulation, then install the upper top plate 1, and tighten it by passing bolts through the bolt holes 13 of the upper clamping and 22 of the lower clamping. The overall structure is as follows when the preparations are complete. Figure 6 As shown.
[0032] The core is rotated 90° and transported in this state.
[0033] After transportation is completed, the coil assembly process begins: the iron core is laid flat, and the top plate 1 and upper clamp insulation are removed; the iron core is pulled out, the coil is installed, and the angled iron core is gradually inserted back in; the upper clamp insulation is placed, the top plate 1 is installed back, and then the iron core is stood up for subsequent assembly.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
