DETAILED DESCRIPTION

[0031] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0032] like Figure 1-2 As shown, this embodiment provides a straightening mold for coil production, including a support plate 20, with side panels 3 symmetrically arranged at the upper and lower ends of the support plate 20. There are four side panels 3 in total, two of which are arranged at the top and two at the bottom. The two side panels 3 located at the top are detachably connected to the support plate 20, while the two side panels 3 located at the bottom are fixedly connected to the support plate 20.

[0033] The middle portion of the support plate 20 is slidably connected to a plurality of horizontal plates 2 affixed to each other, with any adjacent horizontal plates 2 being slidably connected. Limit blocks are provided on both sides of the horizontal plates 2. These limit blocks prevent the horizontal plates 2 from sliding horizontally along the support plate 20 and prevent them from sliding off the support plate 20. The limit blocks limit the movement of the horizontal plates 2, restricting their sliding range to a specified distance.

[0034] The side plate 3 is connected to the vertical plate 14 through a driving mechanism, and the side plate 3 is connected to the bottom plate 7 through a first spring 5. The bottom plate 7 is slidably connected to the side plate 3, and the bottom plate 7 and the vertical plate 14 are perpendicular to each other. The bottom plate 7 and the vertical plate 14 are slidably connected; the bottom plate 7, the vertical plate 14, the horizontal plate 2 and the support plate 20 cooperate with each other to form a cavity 4 for placing the coil, and there are 4 cavities 4 in total.

[0035] The side plate 3 is provided with a sliding groove, and the first spring 5 is slidably arranged in the sliding groove. One end of the first spring 5 is connected to the sliding groove, and the other end of the first spring 5 is connected to the bottom plate 7. The bottom plate 7 is slidably connected to the sliding groove. The first spring 5 is always in a compressed state, so that the bottom plate 7 can always be in close contact with the vertical plate 14.

[0036] One end of the horizontal plate 2 is positioned outside the support plate 20, and both ends of the horizontal plate 2 are provided with a number of small grooves adapted to fit the vertical plates 14. In the initial state, the vertical plates 14 slide in the small grooves. The small grooves facilitate the cooperation between the vertical plates 14 and the horizontal plates 2. Under the action of the small grooves, the vertical plates 14 and the horizontal plates 2 can maintain close contact, ensuring that after adjustment, there will be no holes on the top that would affect the glue effect.

[0037] A large groove is formed on the upper end of the support plate 20 , and an inserting block 1 adapted to the large groove is fixedly connected to the side plate 3 above, and the inserting block 1 is slidably arranged in the large groove.

[0038] Several limiting grooves 16 are provided in the large groove, and a sliding groove 19 is provided in the insert block 1. A second spring 18 is slidably connected in the sliding groove 19. One end of the second spring 18 is connected to the sliding groove 19, and the other end of the second spring 18 is connected to a positioning ball 17 adapted to the limiting groove 16.

[0039] The second spring 18 is always in a compressed state, so that the positioning ball 17 can be in close contact with the limiting groove 16. The positioning ball 17 plays a role in positioning the movement of the insert block 1.

[0040] The drive mechanism includes a vertical bolt 12. A vertical threaded block 13 is fixedly connected to a vertical plate 14. The vertical bolt 12 is threadedly connected to the vertical threaded block 13. After passing through the vertical threaded block 13, the vertical bolt 12 is rotationally connected to the base plate 7. The vertical bolt 12 is always in rotational contact with the base plate 7. Therefore, when the vertical bolt 12 moves, it drives the base 7 to move. Furthermore, when the vertical bolt 12 rotates, the distance between the vertical threaded block 13 and the base plate 7 increases, thereby enabling vertical movement of the vertical plate 14.

[0041] The vertical thread block 13 is fixedly connected to the slide rail 8, the slide rail 8 is slidably connected to the slider 11, the side plate 3 is fixedly connected to the horizontal thread block 10, the horizontal thread block 10 is threadedly connected to the horizontal bolt 9, and the horizontal bolt 9 passes through the horizontal thread block 10 and is rotatably connected to the slider 11.

[0042] The slide rail 8 and the slider 11 can slide relative to each other. Therefore, when the vertical plate 14 moves in the vertical direction, the slider 11 slides relative to the slide rail 8, thereby not affecting the position setting of the horizontal bolt 9.

[0043] A vertical scale 15 is provided on the vertical plate 14, and a horizontal scale 6 is provided on the bottom plate 7. The width and length of the cavity 4 can be adjusted more conveniently through the scale, so as to facilitate the processing of coils of different specifications.

[0044] A method for using a straightening mold for coil production is characterized in that the method uses the above-mentioned straightening mold for coil production, including the following steps:

[0045] S1: Remove the upper side plate 3 and the support plate 20, then pull the horizontal plate 2 toward the end away from the support plate 20, so that the end of the horizontal plate 2 close to the cavity 4 and the end of the support plate 20 close to the cavity 4 form a flat surface;

[0046] S2: The vertical plate 14 is then driven by the driving mechanism to move in the vertical and horizontal directions, thereby adjusting the width and length of the cavity 4. During this process, the vertical plate 14 drives the bottom plate 7 to slide relative to the side plate 3, and the first spring 5 is compressed, so that the bottom plate 7 and the vertical plate 14 are in close contact;

[0047] S3: Then, the two coils are placed on the two bottom plates 7 located below, and then the corresponding horizontal plates 2 are moved toward the cavity 4, so that the vertical plates 14 located below are moved into the small grooves in the horizontal plates 2, and then the two coils are placed above the horizontal plates 2 on both sides.

[0048] S4: Connect the upper side plate 3 to the support plate 20, and move the upper vertical plate 14 into the small groove in the horizontal plate 2, so that the cavity 4 forms an area for placing the coil, and then process the coil.

[0049] The method for disassembling the side panel 3 and the support plate 20 includes: by moving the upper side panel 3 out, at which time the positioning ball 17 and the limiting groove 16 slide relative to each other, causing the second spring 18 to be compressed, and then the positioning ball 17 slides and contacts the inner wall of the large groove, thereby moving the upper side panel 3 out.

[0050] In step S2;

[0051] The method for the driving mechanism to drive the vertical plate 14 to move horizontally includes: by rotating the horizontal bolt 9, the horizontal bolt 9 drives the vertical threaded block 13 and the vertical plate 14 to move horizontally through the slider 11 and the slide rail 8, and at the same time, the vertical bolt 12 drives the bottom plate 7 to slide relative to the side plate 3, and the first spring 5 is compressed;

[0052] The method for the driving mechanism to drive the vertical plate 14 to move vertically includes: by rotating the vertical bolt 12, the vertical bolt 12 drives the vertical plate 14 to move vertically through the vertical threaded block 13, at this time, relative rotation occurs between the vertical bolt 12 and the bottom plate 7.

[0053] In step S3, when placing the horizontal plate 2, the vertical plate 14 can be driven to move away from the horizontal plate 2 by the vertical bolt 12, and then the corresponding horizontal plate 2 can be inserted into the cavity 4. At this time, the vertical bolt 12 is rotated to allow the vertical plate 14 to be inserted into the small groove of the horizontal plate 2, and as the vertical bolt 12 rotates, the vertical plate 14 and the horizontal plate 2 can be in close contact.

[0054] It should be noted that the upper side panel 3 and the support plate 20 are detachably connected. Under the action of the second spring 18, the positioning ball 17 can be in close contact with the limiting groove 16, thereby facilitating the disassembly of the side panel 3. The retractable positioning ball 17 can not only achieve accurate positioning of the side panel 3, but also, when placing the coil, no auxiliary tools are required, and the disassembly of the side panel 3 can be achieved more conveniently and quickly. By removing the side panel 3 upward, it is convenient to place the coil in the cavity 4, thereby effectively improving the efficiency of coil processing, facilitating large-scale coil processing, and having extremely high promotion value.

[0055] In addition, when the horizontal bolt 9 rotates, it can drive the vertical plate 14 to move horizontally, and can drive the bottom plate 7 and the side plate 3 to slide relative to each other through the vertical bolt 12, thereby compressing the first spring 5. Under the action of the first spring 5, the bottom plate 7 and the vertical plate 14 can be in close contact to ensure that there will be no holes on the bottom surface after the adjustment is completed, affecting the gelling effect. When the vertical bolt 12 rotates, it can also drive the vertical plate 14 to move in the vertical direction, thereby realizing the change of the width and length in the cavity 4, thereby being suitable for the pressing work of coils of different models, improving the diversity of mold pressing, and having high versatility, high production efficiency, safety and reliability, and easy use.

[0056] In addition, several horizontal plates 2 fit together, and according to the distance that the vertical plate 14 moves in the vertical direction, the corresponding horizontal plates 2 can be driven to extend, so that the horizontal plates 2 can always be in close contact with the vertical plates 14, ensuring that there will be no holes on the top after the adjustment, which will affect the gelling effect. The horizontal plates 2 also play a supporting role for the coils, so the lengths and widths of the four cavities 4 do not need to be adjusted at the same time, so that the lengths and widths of the four cavities 4 can be adjusted separately. Therefore, the same mold can be used to press coils of different types, effectively improving the diversity of mold pressing, and has high versatility, high production efficiency, safety and reliability, and is easy to use.

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
