Description

Technical Field

[0001] The present invention relates to the technical field of transformer silicon steel sheet lamination, in particular to a lamination device for transformer silicon steel sheets. Background Art

[0002] Silicon steel sheets are a ferromagnetic material containing silicon, coated with an insulating coating. When the transformer is operating, the iron core is in an alternating magnetic field. Based on the principle of electromagnetic induction, eddy currents are generated inside the core, causing the core to heat up and resulting in energy loss. If a single iron core is used, the eddy current path is long, the resistance is low, the eddy current intensity is high, and the loss is significant. However, when the silicon steel sheets are stacked, the insulating coating blocks the eddy current flow path, confining the eddy current to the interior of each silicon steel sheet, shortening the path and increasing the resistance, thereby significantly reducing eddy current losses and improving transformer efficiency. In transformer production, silicon steel sheets must be stacked layer by layer in a specific direction to form a closed magnetic circuit.

[0003] However, when aligning the punched hole in the silicon steel sheet with the positioning rod, if the diameter of the positioning rod is the same as that of the punched hole in the silicon steel sheet, the friction between the silicon steel sheet and the positioning rod becomes greater when the silicon steel sheet is moved downward, and the stacking is less smooth; when the punched hole diameter is larger than the positioning rod diameter, the bottom silicon steel sheet is prone to shaking during the stacking process, which can easily affect the subsequent placement of the silicon steel sheets; in addition, after the silicon steel sheets are stacked, their edges need to be repeatedly adjusted to be neat, and sometimes the operator needs to use tools to knock on their edges, which has a low alignment efficiency, and excessive knocking force can easily cause the stacked silicon steel sheets to shift as a whole, thereby reducing the stacking accuracy. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a lamination device for transformer silicon steel sheets.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a lamination device for transformer silicon steel sheets, including a frame, a base fixedly installed on the top of the frame; a card slot is provided in both the frame and the base; a positioning mechanism is fixedly installed in the card slot; a fixing mechanism is installed on the positioning mechanism; and an alignment mechanism and a leveling mechanism are fixedly installed on the four sides of the frame.

[0006] The top of described supporting plate is fixedly provided with the support frame, and the support frame is fixed with the support frame by bolt.

[0007] Specifically, the fixing mechanism includes a positioning rod and a stop block. The positioning rod is fixedly installed on the support plate by bolts, and the bottom end of the positioning rod is fixedly connected to the stop block. The end of the positioning rod facing away from the support plate is clamped and installed with a cover plate. The top of the cover plate is symmetrically fixed with two hanging rings, and the bottom end of the cover plate is bonded with a rubber pad. The positioning rod passes through the inner wall of the cover plate, the rubber pad and the support plate. The stop block is in contact with the bottom of the support plate, and the width of the stop block is greater than the diameter of the positioning rod.

[0008] Specifically, the alignment mechanism includes a long rod and a fixed frame, long rods are symmetrically fixedly installed on both sides of the frame, a fixed frame is fixedly connected between the two long rods, two hydraulic rods are symmetrically fixedly installed on the fixed frame, the telescopic ends of the hydraulic rods are fixedly installed with a connecting frame, the bottom end of the connecting frame is fixedly installed with a support plate, the telescopic ends of the hydraulic rods are slidably connected to the long rods, the two groups of support plates slide in opposite directions, and the support plates are in contact with the base and the end of the card plate.

[0009] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0010] The beneficial effects of the present invention are:

[0011] (1) The present invention relates to a lamination device for transformer silicon steel sheets. Before laminating the silicon steel sheets, two positioning mechanisms are first symmetrically installed on the base. When the inner wall thereof is tightly fitted with the base, the positioning mechanism can be fixed to the frame by a tool, thereby preventing the positioning mechanism from being displaced and causing deviation in the lamination position during the lamination process. That is, the frame is first placed on a flat ground to ensure that the base fixed on the frame can be in a stable state; when the card plate is installed on the base, the card block fixed at the bottom end of the mounting block can be aligned with the card slot provided in the frame and the base. The inclined surface structure of the card block is tightly fitted with the inner wall of the card slot, and the height of the card block is consistent with the height of the card slot, so that the mounting block can be in conflict with the top of the base, thereby facilitating the fixing of the card block in the frame by bolts; since the mounting block is fixedly connected to the side wall of the support plate by bolts, when the card block is installed in the frame, the bottom end of the support plate will contact the top end of the base. A connecting block is fixed between the support plate and the card plate, and the support plate drives the connecting block to move. The connecting block and the card plate move together, so that the card plate arranged in an L-shaped structure can be snapped together with the base, thereby achieving the fixation of one side card plate; there are sockets at both ends of the card plate, and the limit rods pass through the inner wall of the card plate and are fastened with bolts, so that the two card plates can be assembled together, and the card plate on the other side can also be fixed at the same time, so that the card plates on both sides are tightly fitted with the base, preventing the silicon steel sheet from being placed in a deviation position due to the displacement of the card plate during the lamination process; and then according to the punching position of the silicon steel sheet, a plurality of plug rods are threadedly installed on the top of the card plate. Since a number of groups of balls are installed on the inner equidistant rotation of the plug rods, the punching holes of the silicon steel sheet are aligned with the plug rods and slowly inserted. The rolling action of the balls can reduce the friction between the silicon steel sheet and the plug rods, so that the silicon steel sheet falls smoothly on the card plate, and the L-shaped gasket set at the top of the support plate can also form a preliminary limit for the corners of the silicon steel sheet to prevent the silicon steel sheet from shifting on the card plate; repeat the above steps and stack the silicon steel sheets layer by layer, lightly press the surface of the silicon steel sheet to ensure that the layers are tightly fitted.

[0012] (2) The present invention relates to a stacking device for transformer silicon steel sheets. When stacking, the edges of the stacked silicon steel sheets can be aligned according to the alignment mechanism and leveling mechanism installed around the frame, and the corners of the silicon steel sheets can be limited. That is: during the stacking process, the motor installed at the bottom of the support frame is started, and the motor drives the screw rod to rotate inside the support frame. Since a sliding frame is threadedly installed on the screw rod, the sliding frame is limited by the slide groove set in the support frame. When the screw rod rotates, the sliding frame can only move smoothly along the slide groove part of the support frame to the top of the silicon steel sheet. A clamping plate is installed at the bottom of the sliding frame, and a fixed plate is installed in the clamping plate by bolts. When the fixed plate moves with the sliding frame to a height exceeding the base, one side of the silicon steel sheet can be limited by the fixed plate during the placement of the silicon steel sheet; when the position of the silicon steel sheet is offset, the slider installed on the sliding frame is started. The electric push rod pushes the connecting rod fixed at the end to drive the push plate to move in the direction close to the fixed plate, so that when the push plate contacts the surface of the silicon steel sheet, the silicon steel sheet is pushed to contact the side wall of the fixed plate, thereby limiting the position of the silicon steel sheet between the push plate and the fixed plate, thereby making the silicon steel sheet in a vertical state; then the hydraulic rod installed in the fixed frame can be opened, and the telescopic end of the hydraulic rod slides along the inner wall of the long rod fixed on the frame, and its telescopic end drives the connecting frame and the support plate fixed at the end to move toward both sides of the silicon steel sheet. The two sets of support plates approach the silicon steel sheet synchronously in opposite directions until they contact the side wall of the silicon steel sheet, and the other two sides of the silicon steel sheet can be aligned by uniform thrust; after the leveling is completed, the electric push rod contracts to drive the push plate to reset, and the motor reverses to make the sliding frame return to its initial position; the hydraulic rod drives the support plate to reset, which is convenient for the subsequent overall movement of the stacked silicon steel sheets.

[0013] (3) The stacking device for transformer silicon steel sheets described in the present invention limits the topmost silicon steel sheet in turn through a positioning mechanism and a fixing mechanism, thereby facilitating the fixing of the positioning mechanism and the fixing mechanism together while also facilitating the centralized transportation of the stacked silicon steel sheets, namely: when the silicon steel sheets are stacked to a preset thickness, a positioning block is screwed into the top end of the insertion rod to limit the top silicon steel sheet and also limit the longitudinal displacement of the silicon steel sheet; the through hole of the cover plate is aligned with the positioning rod fixed on the support plate, and the cover plate is slowly lowered to make the rubber pad fit the surface of the top silicon steel sheet, the positioning rod passes through the inner wall of the cover plate and the rubber pad, and the stopper fixed at the bottom end of the positioning rod contacts the bottom of the support plate, which can ensure that the cover plate exerts uniform pressure on the top silicon steel sheet; if transportation is required, the stacked silicon steel sheets can be hoisted as a whole through the lifting ring fixed on the cover plate, and the cooperation of the rubber pad and the positioning rod can also prevent the silicon steel sheets from falling apart.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8As shown, a lamination device for transformer silicon steel sheets according to the present invention includes a frame 1, a base 2 is fixedly mounted on the top of the frame 1; a slot 7 is provided in both the frame 1 and the base 2; a positioning mechanism 5 is fixedly mounted on the slot 7; a fixing mechanism 6 is mounted on the positioning mechanism 5; and an alignment mechanism 3 and a leveling mechanism 4 are fixedly mounted on the four sides of the frame 1.

[0026] Specifically, such as Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the positioning mechanism 5 includes a mounting block 501 and a clamping block 502. The clamping block 502 is fixedly installed on the frame 1 by bolts. The top of the clamping block 502 is fixedly connected to the mounting block 501. The clamping block 502 is located in the clamping slot 7, and the portion where the clamping block 502 contacts the frame 1 and the base 2 is arranged in an inclined structure. The height of the clamping block 502 is equal to the height of the clamping slot 7. The mounting block 501 contacts the top of the base 2. The mounting block 501 is fixedly connected to the side wall of the support plate 503 by bolts. Then, the support plate 503 is fixedly installed with a connecting block 508 on the side wall away from the mounting block 501, and a card plate 509 is fixedly installed on the connecting block 508. The card plate 509 is engaged with the base 2, and a limit rod 510 is fixedly installed between the two card plates 509 by bolts. When the card block 502 is installed in the rack 1, the bottom end of the support plate 503 will contact the top end of the base 2. A connecting block 508 is fixed between the support plate 503 and the card plate 509, and the support plate 503 drives the connecting block 508 and the card plate The top of the support plate 503 is symmetrically bonded with two gaskets 504, and the gaskets 504 and the card plate 509 are both L-shaped. The shaped structure is set up, and according to the punching position of the silicon steel sheet, multiple plug rods 505 are installed on the top thread of the clamping plate 509. Since several groups of balls 507 are installed on the inside of the plug rod 505 for equidistant rotation, the punching of the silicon steel sheet is aligned with the plug rod 505 and slowly inserted. The rolling action of the ball 507 can reduce the friction between the silicon steel sheet and the plug rod 505, so that the silicon steel sheet falls smoothly on the clamping plate 509. The L-shaped gasket 504 set at the top of the support plate 503 can also form a preliminary limit for the corners of the silicon steel sheet to prevent the silicon steel sheet from shifting on the clamping plate 509.

[0027] Specifically, such as Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the fixing mechanism 6 includes a positioning rod 602 and a stopper 604. The positioning rod 602 is fixedly installed on the support plate 503 by bolts, and the bottom end of the positioning rod 602 is fixedly connected to the stopper 604. The stopper 604 contacts the bottom of the support plate 503, and the width of the stopper 604 is greater than the diameter of the positioning rod 602. The stopper 604 contacts the bottom of the support plate 503 to ensure that the pressure of the cover plate 601 on the top silicon steel sheet is uniform; the end of the positioning rod 602 away from the support plate 503 is engaged with the cover plate 601, and the top of the cover plate 601 is symmetrically fixed. It is fixedly connected with two hanging rings 603, and a rubber pad 605 is bonded to the bottom end of the cover plate 601. The positioning rod 602 passes through the inner wall of the cover plate 601, the rubber pad 605 and the support plate 503. The through hole of the cover plate 601 is aligned with the positioning rod 602 fixed on the support plate 503, and the cover plate 601 is slowly lowered to make the rubber pad 605 fit with the surface of the top silicon steel sheet. The positioning rod 602 passes through the inner wall of the cover plate 601 and the rubber pad 605. The stopper 604 fixed at the bottom end of the positioning rod 602 contacts the bottom of the support plate 503, which can ensure that the pressure of the cover plate 601 on the top silicon steel sheet is uniform.

[0028] Specifically, such as Figure 1 、 Figure 2 and Figure 8 As shown, the alignment mechanism 3 includes a long rod 301 and a fixed frame 302. The long rods 301 are symmetrically fixedly installed on both sides of the frame 1, and a fixed frame 302 is fixedly connected between the two long rods 301. Two hydraulic rods 303 are symmetrically fixedly installed on the fixed frame 302. The telescopic ends of the hydraulic rods 303 are slidably connected to the long rods 301. The telescopic ends of the hydraulic rods 303 are fixedly installed with connecting frames 304. The bottom ends of the connecting frames 304 are fixedly installed with abutment plates 305. The two groups of the abutment plates 305 slide in opposite directions, and the abutment plates 305 contact the ends of the base 2 and the clamping plate 509. The telescopic ends of the hydraulic rods 303 slide along the inner walls of the long rods 301 fixed on the frame 1, and the telescopic ends drive the connecting frames 304 and the abutment plates 305 fixed at the ends to move toward the two sides of the silicon steel sheet. The two groups of abutment plates 305 approach the silicon steel sheet synchronously in opposite directions until they contact the side walls of the silicon steel sheet. The other two edges of the silicon steel sheet can be aligned by uniform thrust.

[0029] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, the leveling mechanism 4 includes a support frame 401 and a motor 402. Two support frames 401 are symmetrically fixedly installed on both sides of the frame 1 away from the long rod 301. The bottom end of the support frame 401 is fixedly installed with a motor 402. The output end of the motor 402 is fixedly connected to a screw rod 403 through a coupling. The screw rod 403 is threadedly connected to a sliding frame 404. A slide groove 409 is provided inside the support frame 401. The slide groove 409 is slidably installed with a sliding frame 404, and the width of the sliding frame 404 near the end of the support frame 401 is equal to the width of the slide groove 409, the side wall of the sliding frame 404 is fixedly installed with two electric push rods 405, the telescopic end of the electric push rod 405 is fixedly installed with a connecting rod 408, and the connecting rod 408 is fixedly connected with a push plate 406. The motor 402 drives the screw rod 403 to rotate inside the support frame 401. Since the sliding frame 404 is threadedly installed on the screw rod 403, the sliding frame 404 is supported by the support frame The slide groove 409 provided in 401 is limited. When the screw rod 403 rotates, the sliding frame 404 can only move smoothly along the slide groove 409 of the support frame 401 to the top of the silicon steel sheet; the bottom end of the sliding frame 404 is fixedly installed with a clamping plate 410, and a fixing plate 407 is fixedly installed in the clamping plate 410 by bolts. The push plate 406 contacts the side wall of the base 2, and the fixing plate 407 is slidably connected to the base 2. The screw rod 403 is rotatably connected to the support frame 401. The support frame 401 is arranged in an inverted T-shaped structure. When the position of the silicon steel sheet is offset, the electric push rod 405 installed on the sliding frame 404 is started, and the electric push rod 405 pushes the connecting rod 408 fixed at the end to drive the push plate 406 to move toward the fixed plate 407, so that when the push plate 406 contacts the surface of the silicon steel sheet, it pushes the silicon steel sheet to collide with the side wall of the fixed plate 407, thereby limiting the position of the silicon steel sheet between the push plate 406 and the fixed plate 407, and making the silicon steel sheet in a vertical state.

[0030] When the present invention is used, first, the rack 1 is placed on a flat ground to ensure that the base 2 fixed on the rack 1 is in a stable state; when the card plate 509 is installed on the base 2, the card block 502 fixed at the bottom end of the mounting block 501 can be aligned with the card slot 7 provided in the rack 1 and the base 2. The inclined surface structure of the card block 502 fits tightly with the inner wall of the card slot 7, and the height of the card block 502 is consistent with the height of the card slot 7, so that the mounting block 501 can be in conflict with the top of the base 2, thereby facilitating the passage of the bolts. The clamping block 502 is fixed in the frame 1; since the mounting block 501 is fixedly connected to the side wall of the support plate 503 by bolts, when the clamping block 502 is installed in the frame 1, the bottom end of the support plate 503 will contact the top end of the base 2, and a connecting block 508 is fixed between the support plate 503 and the clamping plate 509. The support plate 503 drives the connecting block 508 and the clamping plate 509 to move together, so that the clamping plate 509 set in the L-shaped structure can be clamped together with the base 2, thereby realizing that the clamping plate 509 on one side can be clamped together. The two ends of the card plate 509 are provided with a socket, and the limit rod 501 passes through the inner wall of the card plate 509 and is fastened with bolts. The two card plates 509 can be assembled together, and the card plate 509 on the other side can also be fixed so that the card plates 509 on both sides are tightly fitted with the base 2 to prevent the position of the silicon steel sheet from being deviated due to the displacement of the card plate 509 during the lamination process; and then a plurality of plug rods 505 are installed on the top of the card plate 509 according to the punching position of the silicon steel sheet. 05 is internally installed with several groups of equidistantly rotating balls 507. The punching holes of the silicon steel sheet are aligned with the insertion rod 505 and slowly inserted. The rolling action of the balls 507 can reduce the friction between the silicon steel sheet and the insertion rod 505, so that the silicon steel sheet falls smoothly on the card plate 509. The L-shaped gasket 504 set on the top of the support plate 503 can also form a preliminary limit for the corners of the silicon steel sheet to prevent the silicon steel sheet from shifting on the card plate 509. Repeat the above steps and stack the silicon steel sheets layer by layer, gently press the surface of the silicon steel sheets to ensure that the layers are tightly fitted.

[0031] When the lamination process is completed, the motor 402 installed at the bottom end of the support frame 401 is started, and the motor 402 drives the screw rod 403 to rotate inside the support frame 401. Since a sliding frame 404 is threadedly installed on the screw rod 403, the sliding frame 404 is limited by the slide groove 409 provided in the support frame 401. When the screw rod 403 rotates, the sliding frame 404 can only move smoothly along the slide groove 409 of the support frame 401 to the top of the silicon steel sheet. A clamping plate 410 is installed at the bottom of the sliding frame 404, and a fixing plate 407 is installed in the clamping plate 410 by bolts. When the fixing plate 407 moves with the sliding frame 404 to a height exceeding the base 2, during the process of placing the silicon steel sheet, one side of the silicon steel sheet can be limited by the fixing plate 407; when the position of the silicon steel sheet is offset, the electric push rod 405 installed on the sliding frame 404 is started, and the electric push rod 405 pushes the connecting rod 408 fixed at the end to drive the push plate 406 to move closer After the cam 406 is in the working state, the cam 406 is in the working state, and the cam 406 is in the working state, so that the cam 406 is in the working state, and the cam 406 is in the working state, so that the cam 406 is in the working state, and the cam 406 is in the working state.

[0032] When the silicon steel sheets are stacked to a preset thickness, a positioning block 506 is screwed into the top end of the insertion rod 505 to limit the top silicon steel sheet and also limit the longitudinal displacement of the silicon steel sheet; align the through hole of the cover plate 601 with the positioning rod 602 fixed on the support plate 503, and slowly lower the cover plate 601 so that the rubber pad 605 fits the surface of the top silicon steel sheet. The positioning rod 602 passes through the inner wall of the cover plate 601 and the rubber pad 605, and the stopper 604 fixed at the bottom end of the positioning rod 602 contacts the bottom of the support plate 503, which can ensure that the pressure of the cover plate 601 on the top silicon steel sheet is uniform; if transportation is required, the stacked silicon steel sheets can be hoisted as a whole through the lifting ring 603 fixed on the cover plate 601, and the cooperation of the rubber pad 605 and the positioning rod 602 can also prevent the silicon steel sheets from falling apart.
