Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, and in particular to a transformer core processing table. Background Technology

[0002] When processing transformer cores, to ensure the proper alignment of steel laminations, especially in the inner lamination structure, a steel plate is often placed at each end. These plates limit the movement of the laminations during stacking. The ends can also be aligned by hammering. However, this hammering method, with its significant impact force, can easily cause deformation at the ends of the steel laminations. This is because the ends of the steel laminations in the middle are machined into a V-shape, which is less resistant to impact under high force, making it prone to deformation. Utility Model Content

[0003] This utility model provides a transformer core processing table to overcome the shortcomings of the prior art and solve the problem of easy deformation of steel sheets during the lamination process, which has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A transformer core processing table includes a rectangular frame with side panels welded to both its inner and outer sides. A central support plate is welded inside the rectangular frame, and side plates are bent downwards on both sides of the central support plate. Multiple pairs of through rods are threaded through the side panels, with the length of the through rods parallel to the length of the central support plate. An outer end plate is welded to the outer end of each pair of through rods. A vertical plate is screwed to the upper end of the outer end plate. Multiple connecting rods are threaded through the vertical plate. An inner clamping plate is provided on the inner end of each connecting rod, and an inner top plate is fitted onto the inner clamping plate. A T-shaped groove is formed on the outer wall of the inner top plate, and the inner clamping plate passes through the T-shaped groove. An outer pressure plate is welded to the outer end of each connecting rod, and an outer extension arm is threaded through the outer pressure plate. An inner top rotating plate is rotatably mounted on the outer end of the outer extension arm, and the inner end of the inner top rotating plate acts on the outer wall of the vertical plate. This solution differs from existing hammering methods. It achieves steel sheet alignment by rotating an inner top plate, which acts on the steel sheets. Furthermore, the alignment process utilizes a gentler force and lower impact, thus preventing deformation of the steel sheet ends. To allow for layer-by-layer steel sheet alignment, the inner top plate is designed to move vertically.

[0006] Furthermore, in order to improve the clamping effect and clamping force during alignment, a pair of arc-shaped plates are welded on the outer wall of the outer pressure plate, and the inner end of the inner top rotating plate acts on the arc-shaped plates.

[0007] Furthermore, to facilitate the rotation of the inner top plate, a handle is welded to the outer end of the inner top plate.

[0008] Furthermore, to facilitate the stacking of steel sheets layer by layer and avoid the influence of connecting rods and other components on the stacking, it is necessary to frequently pull the connecting rods and other components outward during stacking. To facilitate the locking and rapid movement of the connecting rods and other components, a pair of concave seats are provided between the side plates. The inner end of the through rod is located on the concave seat. A pair of outward protruding pins are provided on both sides of the concave seat. A pair of waist-shaped holes are opened on the side plates. The outward protruding pins are inserted into the waist-shaped holes. An end cap is provided on the outer end of the outward protruding pin. A spring is sleeved on the outer end of the outward protruding pin. The inner end of the spring abuts against an inner pressure plate. The inner pressure plate is sleeved on the outward protruding pin. A limiting rotating plate is rotatably provided on the inner pressure plate. The inner end of the limiting rotating plate acts on the side plate.

[0009] Furthermore, in order to improve the stability of the connection between the limiting plate and the side plate, multiple slots are provided on the side plate along its length, and the inner end of the limiting plate is locked in the slots.

[0010] The advantages of the above technical solution are:

[0011] This invention solves the problem that the ends of the steel sheet are easily deformed by hammering, and improves the quality of the transformer core. Attached Figure Description

[0017] like Figures 1-4 As shown, a transformer core processing table includes a rectangular frame 1, with a surrounding plate 10 welded to both the inner and outer sides of the rectangular frame 1, a central support plate 2 welded to the inside of the rectangular frame 1, and side plates 22 bent downward on both sides of the central support plate 2.

[0018] Multiple pairs of through rods 36 are threaded through the enclosure plate 10. The length direction of the through rods 36 is parallel to the length direction of the central support plate 2. An outer end plate 37 is welded to the outer end of each pair of through rods 36. A vertical plate 38 is installed on the upper end of the outer end plate 37 by screws. Multiple connecting rods 39 are threaded through the vertical plate 38. An inner clamping plate 45 is provided on the inner end of the connecting rod 39. An inner top plate 46 is fitted on the inner clamping plate 45. A T-shaped groove 47 is formed on the outer wall of the inner top plate 46. The inner clamping plate 45 passes through the T-shaped groove 47. An outer pressure plate 40 is welded to the outer end of the connecting rod 39. An outer extension arm 42 is threaded through the outer pressure plate 40. An inner top rotating plate 43 is rotatably provided on the outer end of the outer extension arm 42. A handle 44 is welded to the outer end of the inner top rotating plate 43. The inner end of the inner top rotating plate 43 acts on the outer wall of the vertical plate 38. In addition, a pair of arc-shaped plates 41 can be welded to the outer wall of the outer pressure plate 40, and the inner end of the inner top rotating plate 43 acts on the arc-shaped plates 41.

[0019] A pair of concave seats 3 are provided between the side plates 22. The inner end of the through rod 36 is provided on the concave seat 3. A pair of outward protruding pins 30 are provided on both sides of the concave seat 3. A pair of waist-shaped holes 21 are provided on the side plate 22. The outward protruding pins 30 are inserted through the waist-shaped holes 21. An end cap is provided on the outer end of the outward protruding pin 30. A spring 31 is sleeved on the outer end of the outward protruding pin 30. The inner end of the spring 31 abuts against an inner pressure plate 32. The inner pressure plate 32 is sleeved on the outward protruding pin 30. A limiting rotating plate 33 is rotatably provided on the inner pressure plate 32. The inner end of the limiting rotating plate 33 acts on the side plate 22. Alternatively, multiple slots can be provided along the length of the side plate 22. The inner end of the limiting rotating plate 33 is engaged in the slots.

[0020] This embodiment follows the existing processing method for stacking transformer steel sheets. First, multiple layers of steel sheets are placed on the rectangular frame 1. Then, the positions of the stacked steel sheets are calibrated according to design standards. After calibration, multiple layers of steel sheets are placed on the central support plate 2. During stacking, the inner top plate 46 is used to align the two ends of the steel sheets. This process is repeated layer by layer to complete the stacking of the steel sheets. This operation is a conventional method used by those skilled in the art, and therefore only briefly described. This embodiment mainly focuses on the alignment of the two ends of the steel sheets, which will be explained in detail below.

[0021] During stacking, to avoid the inner top plate 46 and connecting rod 39 affecting the stacking operation of the steel sheets, the limiting plate 33 is rotated outward when stacking the outer steel sheets to cancel the force exerted by the limiting plate 33 on the side plate 22 or to remove it from the slot. Then, the inner top plate 46 and connecting rod 39 are pulled outward, and the stacking operation of the outer steel sheets is then carried out.

[0022] When stacking steel sheets in the middle, the inner top plate 46 and connecting rod 39 are moved inward first, and then the limiting rotating plate 33 is rotated. During the rotation, the inner end will act on the side plate 22 or the corresponding slot. During the tightening process, the spring 31 will be compressed, so that after fixing, the elastic force provided by the spring 31 ensures the effect between the limiting rotating plate 33 and the side plate 22.

[0023] When adjusting the position of the inner top plate 46 and the connecting rod 39, the inner top plate 46 needs to be pulled upwards so that it is placed on the middle support plate 2, or on the steel sheet at the top layer. Then, the operator rotates the inner top rotating plate 43. When the inner top rotating plate 43 rotates, its inner end will act on the arc surface of the arc plate 41, thereby causing the outer pressure plate 40 and the inner top plate 46 to move inwards. When the steel sheets are stacked, the two ends of the steel sheets can be limited, thus ensuring that the two ends of the steel sheets are aligned when stacked. Precise alignment can also be achieved by controlling the rotation angle of the inner top rotating plate 43.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
