Description

Technical Field

[0001] This application relates to the field of electromagnetic technology, specifically to a sliding detachable iron core lower mold device. Background Technology

[0002] In the field of transformer core manufacturing, the lamination of silicon steel sheets is a core process. The lamination accuracy directly affects the transformer's energy efficiency and noise level; therefore, strict control over the positioning and alignment of the silicon steel sheets is necessary during the lamination process. Traditional processing equipment typically employs a fixed template structure (e.g., a rigid platform based on mechanical limit blocks or threaded locking) to ensure consistent lamination positions through physical constraints. However, this approach suffers from low demolding efficiency and a risk of lamination deformation. After stacking multiple layers of silicon steel sheets (e.g., more than 50 layers), the formed core must be removed from the fixed template. Due to the tight contact surface between the template and the core, existing technologies typically rely on manual prying or external clamps for forced separation. This process is prone to uneven stress, leading to lateral displacement or interlayer misalignment of the stacked silicon steel sheets, severely impacting the finished product yield. Furthermore, the fixed template requires frequent disassembly of limit components or fasteners during the demolding stage, resulting in low processing efficiency.

[0003] It is evident that the rigid constraints of fixed templates in existing technologies make it difficult to simultaneously improve processing efficiency, finished product accuracy, and equipment reliability. Therefore, there is an urgent need to develop a new type of lamination equipment that can ensure the positioning accuracy of silicon steel sheet stacking, achieve rapid and non-destructive demolding, and adapt to the needs of large-scale production. Utility Model Content

[0004] In view of the above problems, this application provides a sliding detachable iron core lower mold device to solve the technical problems of poor efficiency and accuracy of iron core lamination.

[0005] To achieve the above objectives, this application provides a sliding detachable iron core lower die device, used to be mounted on an iron core stacking machine to support iron cores stacked by the iron core stacking machine, comprising:

[0006] A sliding track is horizontally positioned longitudinally in the stacking area of ​​the core laminating machine;

[0007] A substrate for supporting the iron core, the back of the substrate is provided with a downward protrusion, a slider and two or more rollers; the slider is located at the rear of the substrate and slides in cooperation with the sliding track, the rollers are located on both sides of the front of the substrate and are used to roll and support the front of the substrate; the downward protrusion is located at the rear of the substrate and protrudes downward.

[0008] The substrate can move forward along the sliding track so that the lower convex part abuts against the first limiting block. The substrate can move backward to disengage the slider from the sliding track, so as to remove the substrate and the stacked iron cores from the iron core laminator.

[0009] Further, two or more of the rollers are respectively arranged on both sides of the substrate, and the rollers on the same side are arranged along the extending direction of the sliding track.

[0010] Further, it includes two mutually parallel sliding tracks, and four sliders are arranged on the back of the substrate; two sliders are arranged at the rear of the substrate, and the other two sliders are arranged in the middle of the substrate.

[0011] Further, an operation window is opened at the rear of the substrate. The operation window is located in front of the lower convex part, and when the substrate slides to the position where the lower convex part abuts against the first limiting block, the first limiting block and the lower convex part are located in the operation window; the first limiting block is provided with a locking structure for locking the lower convex part.

[0012] Further, the first limiting block is a "convex" - shaped structure protruding upward. The top of the first limiting block is an upper convex part, the upper convex part abuts against the lower convex part, and the locking structure is arranged on the upper convex part.

[0013] Further, it further includes a second limiting block. The second limiting block is arranged behind the sliding track. When the substrate moves backward to the position where the slider disengages from the sliding track, the lower convex part abuts against the second limiting block.

[0014] Further, the second limiting block is a "convex" - shaped structure protruding upward. Adjusting grooves extending longitudinally are arranged on both sides of the second limiting block, and both sides of the second limiting block are connected to the adjusting grooves, so that the longitudinal position of the second limiting block is adjustable.

[0015] Further, a handle for pushing and pulling the substrate to move along the sliding track is arranged at the front of the substrate.

[0016] Further, a guiding groove adapted to the roller is arranged below the roller, and the guiding groove is parallel to the sliding track.

[0017] Unlike existing technologies, the sliding detachable iron core lower mold device described above includes a base plate for supporting the iron core. A slider is located at the rear of the back of the base plate, and the front is supported by rollers. Therefore, the slider and rollers work together to move along a sliding track. Since there is no slider at the front of the base plate, a small movement is sufficient to detach the base plate from the sliding track, facilitating the removal of the base plate and the iron core together, thus achieving iron core molding. Furthermore, when the base plate moves forward, a downward protrusion located at the rear of the base plate helps to fix the base plate, improving its stability during lamination operations. Therefore, this sliding detachable iron core lower mold device can be stably installed on a lamination machine and allows for convenient and rapid sliding demolding.

[0036] Please see Figures 1 to 4 This embodiment uses a sliding, detachable lower die device 4 for the iron core. This sliding, detachable lower die device 4 is used in conjunction with an iron core laminating machine. For example... Figure 1The diagram shows the structure of the core laminating machine. The core laminating machine includes a support frame and a stacking gripper 1 mounted on the support frame. Two parallel longitudinal tracks 3 are mounted on the support frame, and a gantry frame is mounted on the two longitudinal tracks 3. A transverse track 2 is mounted on the gantry frame. The stacking gripper 1 is movably mounted on the transverse track 2 and is driven to move along the transverse track 2 by a transverse motor 21. Figure 1 and Figure 3 As shown, the lower part of the stacking gripper 1 is provided with an extension rod 11, and the end of the extension rod 11 is provided with a suction cup 111 for adsorbing the iron core 20. The extension rod 11 allows the suction cup 111 to reach down to the bottom of the iron core fixing plate 5 to adsorb the iron core 20.

[0037] The central part of the core stacking machine is the core stacking area 20, which is the area where core stacking operations are performed. The sliding detachable core lower die device 4 is located in the stacking area. The stacking gripper 1 grabs the cores 20 from the core fixing plates 5 on both sides of the core stacking machine and stacks them onto the sliding detachable core lower die device 4. Multiple core fixing plates 5 are provided on both sides of the core stacking machine, and two or more cores of different shapes are placed on each core fixing plate 5. The stacking gripper 1 alternately grabs different cores 20 and stacks them onto the sliding detachable core lower die device 4, thereby forming a closed core body. When the cores 20 are stacked to a predetermined number, the sliding detachable core lower die device 4 is detached from the core stacking machine. Then, a clamp removes the sliding detachable core lower die device 4 along with the cores 20 on it. An empty sliding detachable core lower die device 4 is then inserted into the stacking area for core stacking operations.

[0038] like Figure 2 As shown, in this embodiment, the sliding detachable iron core lower mold device 4 includes: a sliding track 42, a base plate 41, and a limiting block 43. The limiting block 43 includes a first limiting block 431 and a second limiting block 432. The sliding track 42 is horizontally arranged longitudinally in the stacking area of ​​the iron core stacking machine; the longitudinal direction is... Figure 2 The direction indicated by the middle arrow Y is the same as the direction indicated by the horizontal arrow X. The sliding track 42 is fixedly mounted on the support or table surface of the stacking area. The base plate 41 is used to support the iron core 20, and the base plate 41 can be a plate made of aluminum or aluminum alloy. The back of the base plate 41 is provided with a downward protrusion 435, a slider 44, and two or more rollers 45; the slider 44 is located at the rear of the base plate 41 and slides in cooperation with the sliding track 42, the rollers 45 are located on both sides of the front of the base plate 41, and are used to roll and support the front of the base plate 41; the downward protrusion 435 is located at the rear of the base plate 41 and protrudes downward 435.

[0039] The substrate 41 can move forward along the sliding track 42, so that the lower protrusion 435 abuts against the first limiting block 431. The substrate 41 can move backward so that the slider 44 disengages from the sliding track 42, so as to remove the substrate 41 and the stacked iron core 20 from the iron core stacking machine.

[0040] To ensure the smooth sliding of the substrate 41, two sliding tracks 42 are preferably provided. The sliding tracks 42 can be I-shaped tracks or other tracks with cross-sectional shapes commonly used in the art. In order to allow the slider 44 to separate or re-engage with the sliding track 42, no track limiting block 43 is provided at the rear end of the sliding track 42.

[0041] Therefore, in this embodiment, a slider 44 is provided at the rear of the back side of the substrate 41, and the front is supported by a roller 45. The slider 44 and the roller 45 can stably support the substrate 41 and the iron core 20 stacked on it, and allow the substrate 41 to move along the sliding track 42. Since the front of the substrate 41 is not provided with a slider 44 in this embodiment, but is supported by a roller 45, the substrate 41 can be detached from the sliding track 42 with a small movement, making it easy to remove the substrate 41 and the iron core 20 on it together, thus realizing the iron core molding. Furthermore, when the substrate 41 moves forward into place, the lower protrusion 435 on the substrate 41 abuts against the first limiting block 431, which can fix the substrate 41 and improve the stability of the substrate 41 during the stacking operation. Therefore, this sliding detachable iron core lower mold device 4 can be stably installed on the stacking machine and can also facilitate quick sliding demolding.

[0042] In one embodiment, to improve the support strength and stability of the substrate 41 during movement, two or more rollers 45 are respectively provided on both sides of the substrate 41, and the rollers 45 on the same side are arranged along the direction extending from the sliding track 42. Figure 2 As shown, in this embodiment, two rollers 45 are provided on both sides of the front part of the substrate 41 along the longitudinal direction.

[0043] like Figure 2 As shown, in this embodiment, two parallel sliding tracks 42 are included, and four sliders 44 are provided on the back of the substrate 41; two sliders 44 are located at the rear of the substrate 41, and the other two sliders 44 are located at the middle of the substrate 41. When the substrate 41 moves forward to its position, all four sliders 44 are connected to the sliding tracks 42, and the front of the substrate 41 is supported by multiple rollers 45, thus greatly improving the support strength and stability of the substrate 41.

[0044] like Figure 2As shown, in some embodiments, in order to improve the stability of the front-end movement when the substrate 41 moves, a guiding groove 441 adapted to the roller 45 is provided below the roller 45, and the guiding groove is parallel to the sliding track 42. The width of the guiding groove is slightly larger than the width of the roller 45, and the roller 45 can be limited within the groove through the guiding groove, so that the roller 45 can only roll along the direction of the guiding groove.

[0045] As Figure 2 and Figure 4 As shown, in this embodiment, an operation window 433 is formed by hollowing out a corresponding part of the substrate 41 at the rear of the substrate 41. The operation window 433 is located in front of the lower convex part 435, and when the substrate 41 slides to a position where the lower convex part 435 abuts against the first limiting block 431, the first limiting block 431 and the lower convex part 435 are located within the operation window 433; the first limiting block is provided with a locking structure for locking the lower convex part 435.

[0046] The operation window 433 is used to lock the lower convex part 435 and the first limiting block 431. The operation window 433 can be in different shapes such as circular, square, etc., and the size of the operation window 433 can be set according to the sizes of the first limiting block 431 and the lower convex part 435, so as to expose the first limiting block 431 and the lower convex part 435.

[0047] As Figure 2 and Figure 4 As shown, the first limiting block 431 has a "convex" - shaped structure protruding upward. The top of the first limiting block 431 is an upper convex part, and the upper convex part abuts against the lower convex part 435, and the locking structure is arranged on the upper convex part.

[0048] The first limiting block 431 can be made of structural members with high structural strength such as steel, aluminum alloy, etc. In this embodiment, the locking structure is a locking hole 4311, and a threaded hole is provided at a position corresponding to the locking hole on the lower convex part 435, that is, a fixing part 434 is provided on the lower convex part, and the locking hole is arranged on the fixing part. Therefore, by passing a bolt through the locking hole and connecting it to the threaded hole on the lower convex part 435, the lower convex part 435 and the substrate 41 can be locked to the first limiting block 431, so as to prevent the substrate 41 from accidentally sliding during the lamination operation. In other embodiments, the locking structure can also be a snap - type locking structure, a ball - type locking structure and other conventional locking structures in the mechanical field.

[0049] As Figure 2 and Figure 3As shown, in this embodiment, it further includes a second limiting block 432. The second limiting block 432 is arranged behind the sliding track 42. When the substrate 41 moves backward to the position where the slider 44 is disengaged from the sliding track 42, the lower convex portion 435 abuts against the second limiting block 432. The second limiting block 432 is in a "convex" shape protruding upward. The structure of the second limiting block 432 can be the same as that of the first limiting block 431, and will not be repeated here. The second limiting block 432 can make the substrate 41 stop at a specified position after disengaging from the sliding track 42, so it is convenient for the fixture for automatic control to pick up the substrate 41 and the iron core thereon.

[0050] As Figure 3 shown, adjustment grooves 436 extending longitudinally are provided on both sides of the second limiting block 432. Both sides of the second limiting block 432 are connected to the adjustment grooves, so that the longitudinal position of the second limiting block 432 is adjustable. That is, the adjustment grooves extend along the Figure 2 direction indicated by the arrow Y in the figure, so the relative distance between the second limiting block 432 and the sliding track 42 can be adjusted.

[0051] As Figure 2 shown, in order to facilitate pushing and pulling the substrate for demolding or loading the substrate into the sliding track 42, a handle 46 for pushing and pulling the substrate to move along the sliding track 42 is provided at the front of the substrate 41. The handle 46 is integral with the substrate 41. The handle 46 can be formed by hollowing out a part of the material at the front of the substrate 41. In some other embodiments, the handle can also be a split type, and the handle 46 is fixed to the front of the substrate 41 by bolts.

[0052] Finally, it should be noted that although the above embodiments have been described in the text of the specification and drawings of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application, using the content recorded in the text of the specification and drawings of this application, and any technical solutions directly or indirectly implementing the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
