Description

Technical Field

[0001] This utility model relates to the field of transformer core processing technology, and more specifically to a silicon steel sheet stacking device for manufacturing transformer cores. Background Technology

[0002] Silicon steel sheets used in transformer core manufacturing are a type of silicon-containing alloy steel widely used in transformer core production due to their excellent magnetic permeability. Silicon steel sheets have a small hysteresis loop, effectively reducing hysteresis losses and thus lowering the heat generated by the core. Furthermore, by processing silicon steel sheets into sheets and insulating them before laminating them, eddy current losses can be further reduced, further lowering the temperature rise of the core.

[0003] Currently, during the stacking process of silicon steel sheets, multiple silicon steel sheets need to be passed through positioning rods. These positioning rods are used to limit the stacked silicon steel sheets, allowing them to be initially stacked into the shape of a transformer core. After stacking, the silicon steel sheets need to be fixed by binding or clamping. In order to remove the stacked silicon steel sheets, they are often manually moved through the positioning rods and then removed for use. This method is quite cumbersome and needs improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a silicon steel sheet stacking device for manufacturing transformer cores, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a silicon steel sheet stacking device for transformer core manufacturing, including a stacking platform, a stacking support platform fixedly installed on the top of the stacking platform, a support plate provided below the stacking platform, a plurality of positioning rods provided on the top of the support plate, and screws fixedly connected to the bottom ends of the plurality of positioning rods. A plurality of threaded grooves are opened on the top of the support plate, and the outer wall threads of the screws are installed inside the threaded grooves. The top ends of the plurality of positioning rods movably penetrate through the interior of the stacking platform and the stacking support platform and extend to the top of the stacking support platform. An installation groove is opened at the bottom of the stacking platform, and two limiting blocks are slidably connected inside the installation groove. Connecting frames are hinged on both sides of the top of the support plate, and the number of connecting frames is two. The top ends of the two connecting frames are hinged to the bottom of the two limiting blocks.

[0006] Furthermore, the mounting groove is equipped with a bidirectional lead screw, the two ends of which are rotatably mounted on both sides of the inner wall of the mounting groove via bearings, and the two limiting blocks are internally symmetrically threaded to the outer wall of the bidirectional lead screw.

[0007] Furthermore, the mounting groove is provided with a worm and a worm wheel, the worm and the worm wheel mesh with each other, and the worm wheel is fixedly sleeved in the middle of the outer wall of the bidirectional lead screw.

[0008] Furthermore, a geared motor is fixedly installed on the top of the stacking platform, and the output end of the geared motor extends into the interior of the mounting groove and is fixedly connected to the top of the worm gear.

[0009] Furthermore, a mounting plate is fixedly connected to the lower center of the mounting groove, and the bottom end of the worm gear is rotatably mounted on the top of the mounting plate via a bearing.

[0010] Furthermore, support frames are fixedly connected to the four corners of the bottom of the stacking platform. A limiting groove is opened on one side of the support frame, and limiting sliders are fixedly connected to both sides of the support plate. The outer wall of the limiting slider is slidably connected to the inside of the limiting groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model utilizes a combination of a geared motor, worm gear, mounting plate, worm wheel, double-acting screw, limit block, and connecting frame to facilitate the vertical movement of the support plate.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The silicon steel sheet stacking device for manufacturing transformer cores involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] like Figure 1-8 As shown, a silicon steel sheet stacking device for manufacturing transformer cores includes a stacking platform 1, a stacking support platform 2 fixedly installed on the top of the stacking platform 1, a support plate 48 provided below the stacking platform 1, a plurality of positioning rods 3 provided on the top of the support plate 48, and screws 31 fixedly connected to the bottom ends of the plurality of positioning rods 3. A plurality of threaded grooves 49 are opened on the top of the support plate 48, and the outer wall threads of the screws 31 are installed inside the threaded grooves 49. The top ends of the plurality of positioning rods 3 movably penetrate through the interior of the stacking platform 1 and the stacking support platform 2 and extend to the top of the stacking support platform 2.

[0026] In this embodiment, when stacking silicon steel sheets for transformer core manufacturing, the silicon steel sheets can be passed through the positioning rods 3 and supported by the stacking support platform 2. The transformer core is usually stacked sequentially from five parts: left, right, front, back, and middle. By setting multiple positioning rods 3, the silicon steel sheets in different parts can be limited, which facilitates the stacking of silicon steel sheets. If the positioning rods 3 need to be replaced, the screw 31 at the bottom of the positioning rod 3 can be screwed out from the inside of the threaded groove 49 by rotating the positioning rod 3. Then, the bottom of the positioning rod 3 can be pulled out from the inside of the stacking platform 1 and the stacking support platform 2 to disassemble the positioning rod 3. During installation, the positioning rod 3 can be quickly fixed by screwing the screw 31 at the bottom of the positioning rod 3 in the opposite direction into the inside of the threaded groove 49.

[0027] Example 2:

[0028] like Figure 1-8 As shown, the bottom of the stacking table 1 has an installation groove 4. Two limiting blocks 46 are slidably connected inside the installation groove 4. Connecting brackets 47 are hinged to both sides of the top of the support plate 48. There are two connecting brackets 47, and their top ends are hinged to the bottom of the two limiting blocks 46 via rotating shafts. A bidirectional lead screw 45 is installed inside the installation groove 4. The two ends of the bidirectional lead screw 45 are rotatably mounted on both sides of the inner wall of the installation groove 4 via bearings. The two limiting blocks 46 are symmetrically threaded onto the outer wall of the bidirectional lead screw 45. A worm gear 42 and a worm wheel 44 are installed inside the installation groove 4, and the worm gear 42 and worm wheel 44 mesh with each other. The worm gear 44 is internally fixedly sleeved in the middle of the outer wall of the double-acting screw 45. A geared motor 41 is fixedly installed on the top of the stacking table 1. The output end of the geared motor 41 extends into the interior of the mounting groove 4 and is fixedly connected to the top of the worm 42. A mounting plate 43 is fixedly connected to the middle of the lower part of the interior of the mounting groove 4. The bottom end of the worm 42 is rotatably mounted on the top of the mounting plate 43 through a bearing. Support frames 5 are fixedly connected to the four corners of the bottom of the stacking table 1. A limit groove 6 is opened on one side of the support frame 5. Limit sliders 7 are fixedly connected to both sides of the support plate 48. The outer wall of the limit slider 7 is slidably connected to the interior of the limit groove 6.

[0029] In this embodiment, when the silicon steel sheets are stacked on the positioning rods 3 and need to be retrieved, the geared motor 41 and the worm gear 42 work together to drive the worm wheel 44 and the double-acting screw 45 to rotate. The double-acting screw 45 drives the two limiting blocks 46 and the connecting frame 47 to move. The bottom end of the connecting frame 47 drives the support plate 48 to move vertically. The support plate 48 also drives the limiting slider 7 to slide vertically inside the limiting groove 6. The cooperation between the limiting groove 6 and the limiting slider 7 facilitates the vertical guidance of the support plate 48 and maintains the stability of the support plate 48's movement. During the movement of the support plate 48, multiple positioning rods 3 can be moved down to the bottom of the stacking support platform 2, so that the positioning rods 3 can be removed from inside the stacked silicon steel sheets, thereby facilitating the retrieval of the stacked silicon steel sheets.

[0030] In summary, as Figure 1-8As shown, this silicon steel sheet stacking device for transformer core manufacturing allows the silicon steel sheets to pass through the positioning rods 3 and be supported by the stacking support platform 2. After the silicon steel sheets are stacked, the worm gear 42 is driven by the geared motor 41 to rotate above the mounting plate 43. The worm gear 42 also drives the worm wheel 44 and the double-acting screw 45 to rotate. The double-acting screw 45 drives the two limiting blocks 46 to slide relative to each other inside the mounting groove 4. The two limiting blocks 46 also drive the top ends of the two connecting frames 47 to move. The bottom ends of the connecting frames 47 push the support plate 48 to move. The support plate 48 then drives the limiting slider 7 to slide horizontally inside the limiting groove 6. During this movement, the support plate 48 can drive multiple positioning rods 3 to move downwards, allowing the top ends of the multiple positioning rods 3 to be removed from inside the stacked silicon steel sheets, thus facilitating the collection of the stacked silicon steel sheets.
