Description

Technical Field

[0001] This application relates to the field of transformer technology, and more specifically, to an I-beam pasting fixture for a winding mold of a dry-type transformer low-voltage coil. Background Technology

[0002] In the manufacturing process of low-voltage coils of dry-type transformers, the production of winding molds is a crucial step. Traditional processes require manual pasting of multiple I-beams (I-beam-shaped heat sinks) onto the surface of a fiberglass cloth board (glass cloth board). The multiple layers of glass cloth board with I-beams attached are then rolled and welded into a cylindrical mold, using the gaps between the I-beams to form heat dissipation channels.

[0003] However, in practice, to ensure the I-beams are symmetrically distributed circumferentially, workers often use a method of stacking and pasting fiberglass sheets layer by layer. However, the upper fiberglass sheet is prone to sticking to the lower I-beams due to glue seepage, leading to a decrease in product quality or even rendering the product unusable, necessitating time-consuming and labor-intensive rework. To solve this problem, existing improvements involve adding barrier sheets between the fiberglass sheets to prevent direct adhesion between the upper and lower I-beams. However, practice has shown that this improvement is still limited in its effectiveness. The upper fiberglass sheet may still stick to the lower barrier sheet due to glue seepage, requiring manual separation of the adhered fiberglass sheet and barrier sheet. This not only fails to effectively solve the problem but also adds extra production steps, increases production costs, and slows down production progress.

[0004] There is currently no effective technical solution to the above problems. Utility Model Content

[0005] The purpose of this application is to provide a tooling for pasting I-beams on a winding mold for a low-voltage coil of a dry-type transformer, so as to solve the problem of adhesion between the upper glass cloth board and the lower barrier sheet or I-beam, making the pasting process more controllable.

[0006] This application provides an I-beam pasting fixture for a winding mold of a low-voltage coil of a dry-type transformer, including a separator seat and a first support piece, wherein the separator seat and the first support piece are separated.

[0007] The separator has a plurality of separator slots arranged in an array along a first horizontal direction. The separator slots extend vertically and their openings face the first support piece. The separator slots are used to define the storage position of one end of the I-beam.

[0008] The first support plate has a plurality of supports arranged along a first horizontal direction. The supports are used to support the glass cloth board so that the top surface of the glass cloth board is attached to the other end of the I-shaped strip.

[0009] The I-beam bonding fixture for the winding mold of the low-voltage coil of the dry-type transformer of this application is used in conjunction with the first support plate through the use of the separator seat. This achieves rapid and accurate alignment and bonding of the I-beams. The first support plate supports the glass cloth only by relying on multiple supports arranged along the first horizontal direction, which reduces the contact area between the two and effectively solves the problem of adhesion between the upper glass cloth board and the lower first support plate or I-beams. This makes the bonding process more controllable, ensures the placement stability of the glass cloth board, and improves production efficiency and product quality.

[0010] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer has a supporting base plate on the bottom side of the separator seat away from the first support plate, and reinforcing ribs on both sides of the separator seat connecting the supporting base plate.

[0011] The reinforcing ribs, the partition seat, and the supporting base plate together form a triangular structure, thereby increasing the structural strength of the partition seat and reducing the possibility of deformation. Through the synergistic effect of the supporting base plate and the reinforcing ribs, the partition seat effectively solves the problem of insufficient structural strength, ensuring the reliability and stability of the I-beam strip pasting fixture during operation.

[0012] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer, wherein the distribution density of the support body is greater than the distribution density of the partition groove.

[0013] The support structure provides denser support points for the glass cloth sheet, ensuring its placement stability and surface flatness. This effectively prevents deformation of the glass cloth sheet in the lower workpiece, thereby improving the accuracy and quality of the I-beam bonding.

[0014] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer, wherein the width of the dividing groove is greater than the width of the I-beam.

[0015] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer, wherein the support body is an upwardly bent piece formed by stamping the first support piece.

[0016] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer, wherein the bending piece is in the shape of an isosceles triangle.

[0017] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer includes a bending sheet divided into a first bending sheet and a second bending sheet. The first bending sheet and the second bending sheet are alternately arranged on the first support sheet along a first horizontal direction, and the line connecting the tops of the plurality of first bending sheets is parallel to the line connecting the tops of the plurality of second bending sheets.

[0018] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer, wherein the distance between the top end of the first bending piece and the top end of the second bending piece in the second horizontal direction is 1 / 20-1 / 2 of the width of the glass cloth board, and the second horizontal direction is perpendicular to the first horizontal direction.

[0019] The I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer includes, wherein each of the supports comprises two symmetrically arranged round nails fixed to the top surface of the first support plate.

[0020] The I-beam bonding fixture for the winding mold of the low-voltage coil of the dry-type transformer further includes a second support piece with the same structure as the first support piece. The second support piece is disposed on the side of the first support piece near the separator seat and is used to support another glass cloth board so that one end of the I-beam is bonded to the top surface of the glass cloth board.

[0021] As can be seen from the above, the I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer provided in this application, through the cooperation of the separator seat and the first support piece, realizes the rapid and accurate alignment and pasting support of the I-beam. The first support piece only supports the glass cloth based on multiple supports arranged along the first horizontal direction, reducing the contact area between the two, effectively solving the problem of adhesion between the upper glass cloth board and the lower first support piece or I-beam, making the pasting process more controllable, ensuring the placement stability of the glass cloth board, and improving production efficiency and product quality.

[0034] Firstly, please refer to Figures 1-6 Some embodiments of this application provide an I-beam pasting fixture for a winding mold of a low-voltage coil of a dry-type transformer, including a separator 1 and a first support piece 2, wherein the separator 1 and the first support piece 2 are separated.

[0035] The separator 1 has a plurality of separator grooves 11 arranged in an array along the first horizontal direction. The separator grooves 11 extend vertically and the groove openings face the first support piece 2. The separator grooves 11 are used to define the storage position of one end of the I-beam 3.

[0036] The first support plate 2 has multiple supports 21 arranged along the first horizontal direction. The supports 21 are used to support the glass cloth plate 4 so that the other end of the I-shaped strip 3 is pasted on the top surface of the glass cloth plate 4.

[0037] Specifically, the partition groove 11 on the partition seat 1 is used to fix one end of the I-beam 3, ensuring the neatness of the I-beam 3 arrangement, achieving precise alignment of the I-beam 3, so that the I-beam 3 can be pasted on the glass cloth board 4 in an orderly and precise manner, ensuring the quality of product manufacturing.

[0038] More specifically, such as Figure 3 As shown, the separator 1 and the first support piece 2 are used together for precise alignment and support of the I-beam 3, respectively, enabling continuous and rapid pasting of the I-beam 3.

[0039] It should be noted that, as Figure 4 As shown, in actual use, the separator 1 is used in conjunction with multiple first support plates 2: after all the corresponding I-beams 3 are pasted on the glass cloth board 4 on the first support plate 2, the worker places the next first support plate 2 on these I-beams 3, and then places the next glass cloth board 4 on the first support plate 2 to continue pasting the I-beams 3 on the glass cloth board 4. That is, in actual use, the first support plate 2 replaces the original barrier plate and is alternately stacked with the pasted workpiece (the combination of glass cloth board 4 and I-beams 3) to realize the batch continuous pasting process of I-beams 3.

[0040] More specifically, the support body 21 on the first support piece 2 raises the glass cloth plate 4 to a certain height, avoiding direct contact between the glass cloth plate 4 and the surface of the first support piece 2. The first support piece 2 only contacts the glass cloth plate 4 through the top end of the support body 21, reducing the contact area between the two. Even if glue seeps out from the glass cloth plate 4, it will not tightly bond the glass cloth plate 4 to the first support piece 2. The first support piece 2 is used as an isolation carrier for adjacent workpieces. It supports the glass cloth plate 4 based on multiple supports 21 arranged along the first horizontal direction, which can ensure the placement stability of the glass cloth plate 4. Its bottom surface contacts the top surface of multiple I-beams 3 that have been glued to the lower workpiece. The I-beams 3 are generally glued to the glass cloth plate 4 below by applying glue to their bottom surface. Therefore, their top surface will not stick to the first support piece 2 above. The multiple I-beams 3 that have been glued to the first support piece 2 can ensure the flatness of the placement of the first support piece 2, thereby ensuring the processing consistency of the lower workpiece.

[0041] More specifically, the divider 1 can be made of metal or non-metal materials, and the shape and size of the divider groove 11 can be adjusted according to the shape and size of the I-beam 3 to ensure that the I-beam 3 can be stably placed in the divider groove 11.

[0042] More specifically, the opening of the dividing groove 11 is set facing the first support piece 2, which makes it convenient for workers to first use the dividing groove 11 to align one end of the I-beam 3, and then paste the other end of the I-beam 3 onto the glass cloth plate 4 to ensure processing quality.

[0043] More specifically, the support 21 on the first support piece 2 can take many forms. For example, the support 21 can be a bent piece formed by stamping the first support piece 2, or it can be a part fixed to the top surface of the first support piece 2.

[0044] More specifically, the number and arrangement of the supports 21 can be adjusted according to the size of the glass cloth board 4 and the spacing of the I-beams 3 to ensure that the glass cloth board 4 can be stably supported and that the I-beams 3 can be accurately pasted to the top surface of the glass cloth board 4.

[0045] More specifically, the distance between the separator 1 and the first support piece 2 can be adjusted according to the size of the winding die.

[0046] The I-beam bonding fixture for the winding mold of the low-voltage coil of the dry-type transformer in this embodiment of the application is used in conjunction with the first support piece 2 through the partition seat 1, which realizes the rapid and accurate alignment and bonding support of the I-beam 3. The first support piece 2 supports the glass cloth only by multiple supports 21 arranged along the first horizontal direction, which reduces the contact area between the two and effectively solves the problem of adhesion between the upper glass cloth plate 4 and the lower first support piece 2 or I-beam 3. This makes the bonding process more controllable, ensures the placement stability of the glass cloth plate 4, and improves production efficiency and product quality.

[0047] In some preferred embodiments, the bottom of the partition seat 1 on the side opposite to the first support plate 2 has a supporting base plate 12, and the partition seat 1 has reinforcing ribs 13 on both sides that connect to the supporting base plate 12.

[0048] Specifically, the support base plate 12 is fixedly connected to the bottom of the partition seat 1 by bolts, welding, or riveting. This structure increases the contact area at the bottom of the partition seat 1, thereby improving its placement stability. The reinforcing rib 13, together with the partition seat 1 and the support base plate 12, forms a triangular structure, thereby increasing the structural strength of the partition seat 1 and reducing the possibility of deformation. Through the synergistic effect of the support base plate 12 and the reinforcing rib 13, the partition seat 1 effectively solves the problem of insufficient structural strength, ensuring the reliability and stability of the I-beam strip 3 pasting fixture during operation.

[0049] In some preferred embodiments, the distribution density of the support 21 is greater than the distribution density of the partition groove 11.

[0050] Specifically, the distribution density of the support body 21 is greater than that of the partition groove 11, which means that under the same length dimension, the number of support bodies 21 on the surface of the first support piece 2 is greater than the number of partition grooves 11. When the glass cloth plate 4 is placed on the first support piece 2, the support body 21 can provide a denser support point for the glass cloth plate 4, ensuring the placement stability of the glass cloth plate 4 and the flatness of the surface of the glass cloth plate 4, effectively preventing the glass cloth plate 4 in the lower workpiece from deforming, thereby improving the accuracy and quality of the I-beam 3 pasting.

[0051] In some preferred embodiments, the width of the dividing groove 11 is greater than the width of the I-beam 3.

[0052] Specifically, the width of the dividing groove 11 is designed to be greater than the width of the I-beam 3, which ensures that the I-beam 3 can be smoothly placed into the dividing groove 11, avoiding the situation where the I-beam 3 cannot be placed or is difficult to place. In other words, it provides a gap for the placement of the I-beam 3, which can effectively improve the ease of operation.

[0053] More specifically, the placement efficiency of the I-beam strip 3 is improved, which indirectly ensures the efficiency of subsequent I-beam strip 3 pasting. The overall practicality and convenience of the tooling are improved, and it is also convenient to remove the separator seat 1 after all the workpieces have been pasted.

[0054] In some preferred embodiments, the support 21 is an upwardly bent piece formed by stamping the first support piece 2.

[0055] Specifically, the stamping process ensures the manufacturing efficiency and cost-effectiveness of the first support piece 2.

[0056] More specifically, the upward-curving structure allows the bent sheet to make point or line contact with the glass cloth sheet 4, significantly reducing the adhesive contact area between the glass cloth sheet 4 and the support 21. Even if a small amount of adhesive seeps out, the possibility of large-area adhesion between the glass cloth sheet 4 and the support 21 is effectively reduced. At the same time, the bending structure of the bent sheet provides it with sufficient support strength, ensuring that the glass cloth sheet 4 remains stable during the subsequent I-beam 3 pasting process.

[0057] More specifically, the bent sheet refers to a sheet-like structure formed by bending, which is not only easy to manufacture but also provides sufficient structural strength to ensure effective support for the glass cloth plate 4.

[0058] More specifically, the first support piece 2 is stamped from a sheet metal. The stamping equipment processes the sheet metal to integrally form multiple upwardly curved pieces as support bodies 21. The shape of the curved pieces can be designed as triangles, rectangles, or arcs, etc.

[0059] In some preferred embodiments, the bent piece is in the shape of an isosceles triangle.

[0060] Specifically, the isosceles triangular bending sheet structure is stable and can provide reliable support for the glass cloth sheet 4. Compared with other shapes of bending sheets, such as rectangles or circles, the geometric properties of the isosceles triangle make the bending sheet less prone to deformation under pressure, ensuring the stability of the support.

[0061] More specifically, isosceles triangles are easy to manufacture through stamping and bending processes, resulting in high material utilization and reduced manufacturing costs. Compared to other bent sheet shapes, such as rectangles or circles, isosceles triangles may offer better mechanical properties and processing economy while providing stable support.

[0062] More specifically, during the installation of the I-beam strip 3, the glass cloth plate 4 is placed on multiple isosceles triangular bent pieces. These bent pieces are evenly distributed on the first support plate 2, forming multiple support points that collectively bear the weight of the glass cloth plate 4 and the pressure of the I-beam strip 3 adhered to it. Due to the structural stability of the isosceles triangle, each bent piece can effectively resist the pressure from the glass cloth plate 4, preventing the glass cloth plate 4 from bending or deforming, thereby ensuring the flatness of the surface of the glass cloth plate 4. The flat surface of the glass cloth plate 4 provides a uniform force-bearing surface for the adhesion of the I-beam strip 3, ensuring that the I-beam strip 3 can be firmly and flatly adhered to the glass cloth plate 4, thereby improving the manufacturing quality and efficiency of the dry-type transformer low-voltage coil winding mold.

[0063] In some preferred embodiments, the bending pieces are divided into first bending pieces 211 and second bending pieces 212. The first bending pieces 211 and second bending pieces 212 are alternately arranged on the first support piece 2 along a first horizontal direction, and the line connecting the top ends of the plurality of first bending pieces 211 is parallel to the line connecting the top ends of the plurality of second bending pieces 212.

[0064] Specifically, to address the issues of insufficient uniformity and flexibility in the support body 21, the support body 21 is subdivided into two types: a first bent piece 211 and a second bent piece 212. For example... Figure 2 As shown, the two types of bent sheets are arranged alternately along the first horizontal direction on the first support sheet 2.

[0065] More specifically, the tops of the multiple first bent pieces 211 are designed such that the line connecting them is parallel to the line connecting the tops of the multiple second bent pieces 212. This means that the tops of the two types of bent pieces are aligned in the first horizontal direction, forming a flat support surface together. As a result, the glass cloth sheet 4 receives uniform support in the horizontal direction, ensuring the smooth adhesion of the I-beams 3. This structural design reduces the overall rigidity of the support structure while ensuring effective support for the glass cloth sheet 4.

[0066] In some preferred embodiments, the distance between the top end of the first bent piece 211 and the top end of the second bent piece 212 in the second horizontal direction is 1 / 20 to 1 / 2 of the width of the glass cloth plate 4, and the second horizontal direction is perpendicular to the first horizontal direction.

[0067] Specifically, by setting the distance between the tops of the bent pieces within the range of 1 / 20 to 1 / 2 of the width of the glass cloth sheet 4, the glass cloth sheet 4 can be effectively supported in the horizontal direction.

[0068] like Figure 6 As shown, in some other embodiments, each support 21 includes two symmetrically arranged round nails 213 fixed to the top surface of the first support piece 2.

[0069] Specifically, the support 21 consists of two symmetrically arranged round nails 213, designed to reduce the contact area between the support 21 and the glass cloth sheet 4. Symmetrical arrangement means that the two round nails 213 are symmetrically distributed relative to the center position of the support 21 or a predetermined axis, thus enabling the two round nails 213 to support the glass cloth sheet 4 in a balanced manner, ensuring its placement stability. The round nails 213 are fixed to the top surface of the first support piece 2, providing a stable support structure. As point contact, the round nails 213 significantly reduce the contact area with the glass cloth sheet 4 compared to a surface contact support structure, thereby reducing adhesion problems that may be caused by glue seepage. Compared to the implementation using a bent sheet, the structure with round nails 213 offers higher stability, but increases manufacturing costs.

[0070] In some preferred embodiments, the I-beam pasting fixture for the winding mold of the low-voltage coil of the dry-type transformer also includes a second support piece 5 with the same structure as the first support piece 2. The second support piece 5 is disposed on the side of the first support piece 2 near the separator seat 1 and is used to support another glass cloth plate 4 so that one end of the I-beam 3 is pasted on the top surface of the glass cloth plate 4.

[0071] Specifically, by adding a second support piece 5, the fixture can support two glass cloth boards 4 at the same time, so that both ends of the I-beam 3 can be pasted on the two glass cloth boards 4 at the same time, thereby improving processing efficiency.

[0072] It should be noted that after all the I-beams 3 have been pasted, the workers will need to cut off the parts of the I-beams 3 that protrude from the two glass cloth boards 4 later.

[0073] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0074] The above descriptions are merely some embodiments of this utility model.
