Description

Technical Field

[0001] This invention belongs to the field of transformer core manufacturing technology, and specifically relates to a silicon steel sheet material tower turning machine for transformer cores. Background Technology

[0002] The core of an ultra-high voltage transformer is generally made of silicon steel sheets with a thickness of 0.18mm to 0.30mm, which are stacked manually. According to design requirements, the core is arranged in a stepped manner. Each step is called a stage of the core, and the silicon steel sheets of the same stage have the same width.

[0003] The cross-sections of the core's columns and yoke are formed by stacking the inverse and forward stacking materials of the core. Due to the sheet-like structure of the silicon steel sheets, the following situations typically arise, primarily requiring manual material handling:

[0004] 1. The iron core has a four-column structure. The insert plate material in the lower yoke of the iron core needs to be processed by cutting the upper and lower half towers. Two positive tower materials (or negative tower materials) need to be processed, and then one positive tower material (or negative tower material) is flipped into a negative tower material (or positive tower material).

[0005] 2. For the core column splicing material, the upper and lower half towers also need to be cut and processed. Two positive tower materials (or negative tower materials) need to be processed, and then one positive tower material (or negative tower material) is flipped into a negative tower material (or positive tower material).

[0006] 3. When the lower and upper yoke sheets are cut from the same piece, the lower yoke material requires one positive tower piece and one negative tower piece, while the upper yoke material requires two negative tower pieces. Therefore, the upper yoke material is cut in the same manner as the lower yoke material, and then one positive tower piece is flipped into a negative tower piece. Alternatively, the lower yoke material is cut in the same manner as the upper yoke material, and then one negative tower piece is flipped into a positive tower piece.

[0007] 4. In order to improve the shearing efficiency of the cross-cutting line, the material is uniformly cut into positive tower material, and then half of the positive tower material is flipped into negative tower material, which can improve the shearing efficiency by 20%.

[0008] In all the above situations, the silicon steel sheet silo needs to be turned over. Currently, the turning method is manual turning, which is labor-intensive for employees, involves long working hours, and can easily become a bottleneck process that restricts output. At the same time, the manual turning of silicon steel sheets can easily damage the silicon steel sheets and pose a risk of increased unit iron loss of the silicon steel sheets.

[0009] Therefore, how to solve the problem of the flipping of the iron-core silicon steel sheet material tower has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0010] To solve the above problems, the present invention provides a turning machine for iron-core silicon steel sheet material towers, comprising:

[0011] Base;

[0012] A rotating body is placed above the base and rotatably connected to the base. One end of the rotating body in the horizontal direction is the driving end, and the other end is the material cart inlet / outlet end.

[0013] Two mobile material carts are provided, each of which can enter or exit the rotating body from the material cart's inlet / outlet end.

[0014] A material cart conveyor frame is placed outside the rotating body and is used to send the mobile material cart into or out of the rotating body through the material cart inlet and outlet ends;

[0015] The first driving device is connected to the driving end of the rotating body and is used to drive the rotating body to rotate around the horizontal axis.

[0016] The rotating body has an internal hollow structure, and its interior has two material cart stations arranged vertically.

[0017] A fixing clamping device is used to fix and clamp the mobile material cart onto the rotating body;

[0018] During operation, one of the mobile carts is initially positioned at the upper cart station of the rotating body, while the other mobile cart, after receiving the material sheet on the cart conveyor, is sent to the lower cart station of the rotating body. At this time, the fixing and clamping device is activated to fix and clamp the two mobile carts inward. Then, under the drive of the first driving device, the rotating body is rotated 180 degrees to complete the flipping of the material sheet. The cart conveyor then moves the mobile cart at the lower station along with the material sheet out, thus completing one material sheet flipping process.

[0019] Preferably, the present invention may also include the following further improvements.

[0020] Furthermore, the material cart conveyor frame is equipped with a second drive device, a conveyor belt, and connecting parts;

[0021] The conveyor belt is connected to the second drive device in a transmission manner;

[0022] The connector is fixed to the conveyor belt;

[0023] The end of the mobile material cart is equipped with a hook that can move up and down;

[0024] When the mobile material cart needs to be fed into or removed from the rotating body, the hook is engaged with the connector; when the rotating body performs a flipping motion, the hook is disengaged from the connector.

[0025] Furthermore, the end of the mobile material cart is provided with a guide member, the hook is provided with a guide rod, and the guide member is provided with a guide hole that cooperates with the guide rod;

[0026] At the upper and lower workstations of the material cart inlet / outlet, a third driving device is respectively provided to cooperate with the guide rod. The third driving device can drive the hook to move upward, thereby realizing the disengagement action from the connector.

[0027] Furthermore, the fixing and clamping device includes a fixing block located at the bottom of the moving material cart and a locking cylinder located on the rotating body;

[0028] The bottom of the fixing block is provided with an insertion hole, and the end of the drive rod of the locking cylinder is a ball joint. The ball joint can be inserted into the insertion hole for fixing and locking under the action of the drive rod.

[0029] Furthermore, the fixing clamping device also includes a fork, the end of which has a forked structure;

[0030] The bottom of the fixing block is also provided with a sliding groove that is adapted to the fork, and the fork can move freely in the sliding groove;

[0031] The spherical joint has a mating surface at its root that is adapted to the fork.

[0032] After the spherical connector is inserted into the insertion hole, the fork moves along the groove toward the spherical connector, and the two forked structures are inserted into the root of the spherical connector, thus completing the locking and fixing between the moving material cart and the rotating body.

[0033] Furthermore, the groove has a wedge-shaped, trapezoidal, or conical structure.

[0034] Furthermore, each of the mobile carts is provided with four sets of fixing clamping devices, and the four sets of fixing clamping devices are arranged opposite each other in pairs along the width direction of the mobile cart.

[0035] Furthermore, each of the mobile material carts also includes two sets of linkage drive devices at its bottom, each set of linkage drive devices being used to drive a pair of forks to simultaneously insert into and simultaneously remove from the spherical joint.

[0036] Furthermore, the linkage drive device includes:

[0037] First end plate, first limiting rod, first driving rod, first connecting rod, intermediate connecting rod, swing rod, fixed shaft, mounting bracket, second end plate, second limiting rod, second driving rod, second connecting rod;

[0038] The first end plate and the second end plate are arranged opposite each other along the width direction of the moving material cart;

[0039] One end of the first limiting rod is fixed to the inner side of the first end plate, and one end of the second limiting rod is fixed to the inner side of the second end plate;

[0040] The first limiting rod is a cylindrical structure with openings at both ends. The first end plate has a through hole, and the first driving rod passes through the cylindrical structure and exits through the through hole.

[0041] The second drive rod is hinged to the other end of the second limiting rod;

[0042] The two ends of the intermediate connecting rod are fixedly connected to the ends of the first driving rod and the second driving rod, respectively.

[0043] The intermediate connecting rod has through-holes in both the horizontal and vertical directions, including a horizontally narrow hole and a vertically narrow hole.

[0044] The fixed shaft passes through the horizontal elongated hole and is fixed to the mounting bracket, which is fixed to the bottom of the mobile material cart;

[0045] The swing arm passes through the vertical narrow hole;

[0046] The middle part of the swing arm is rotatably connected to the fixed shaft;

[0047] The two ends of the first connecting rod are respectively hinged to one end of the first limiting rod and one end of the swing rod;

[0048] The two ends of the second connecting rod are respectively hinged to the second limiting rod and the other end of the swing rod;

[0049] The first connecting rod, the swing rod, and the second connecting rod form a "Z" shaped structure after installation.

[0050] The fork is fixed to the inner side of the first end plate and the second end plate respectively;

[0051] When the second end plate is pushed inward, the fork fixed to the second end plate moves inward, and at the same time, the fork located on the first end plate also moves inward under the drive of the linkage mechanism.

[0052] When the first drive rod is pushed inward, the first end plate will be pushed outward, thereby causing the fork mounted on the second mounting plate to move outward. At the same time, the fork located on the first end plate also moves outward under the drive of the linkage mechanism.

[0053] Furthermore, a fourth driving device is provided on the rotating body at a position corresponding to the second end plate for pushing the second end plate; and a fifth driving device is provided at a position corresponding to the first driving rod for pushing the first driving rod.

[0054] The present invention provides a silicon steel sheet stack turning machine, which is applicable to the silicon steel sheet stacking tower and sheet pallet in the core workshop production process. It can complete a 180° vertical turning according to process requirements, and has an automatic clamping function during the turning process to prevent sheet tipping, slippage, misalignment, and potential quality risks such as scratches, edge deformation, or breakage of the silicon steel sheets. The equipment as a whole has the advantages of stable operation, safety and reliability, high efficiency, low noise, and low energy consumption. The entire turning process is fully automatic and requires no manual intervention. Attached Figure Description

[0068] A specific embodiment of the iron-core silicon steel sheet material tower turning machine provided by the present invention includes:

[0069] The base 1 can be a steel frame or other types of structure, used to support the rotating body 2 and allow the rotating body 2 to rotate on it;

[0070] A rotating body 2 is placed above the base 1 and is rotatably connected to the base 1. One end of the rotating body 2 in the horizontal direction is the drive end 201, and the other end is the material cart inlet / outlet end 202. The rotatable connection with the base 1 means that the rotating body 2 can rotate on the base 1, and the two are in rolling or sliding contact, preferably rolling contact. For example, the rotating body 2 is provided with a circumferential track, and the top of the base 1 is provided with a roller that cooperates with the track. When the rotating body 2 rotates, the track moves along the roller.

[0071] There are two mobile material carts 3, each of which can enter or exit the rotating body 2 from the material cart inlet / outlet 202; the mobile material carts 3 are used to receive the stacked iron core silicon steel sheet material tower.

[0072] The material cart conveyor 4 is placed outside the rotating body 2 and is used to send the mobile material cart 3 into or out of the rotating body 2 via the material cart inlet / outlet end 202.

[0073] To facilitate the movement of the mobile material cart 3 in and out of the rotating body 2, a preferred embodiment is that the bottom of the mobile material cart 3 is provided with two rows of straight tracks, and the material cart conveyor frame 4 is provided with two rows of rollers arranged at intervals; correspondingly, the rotating body 2 is also provided with rollers arranged at intervals that connect with the rollers on the material cart conveyor frame 4. It can be understood that since the rotating body 2 needs to be able to enter and exit the mobile material cart 3 at both the initial position and the position after rotating 180 degrees, the rotating body 2 needs to be provided with two rows of rollers, one above the other.

[0074] The first driving device 5 is connected to the driving end 201 of the rotating body 2 and is used to drive the rotating body 2 to rotate around the horizontal axis. The first driving device 5 can be a motor or a rack and pinion hydraulic cylinder. To facilitate speed control, a braking device, such as a holding brake, is provided between the first driving device 5 and the rotating body 2.

[0075] The rotating body 2 has an internal hollow structure, and there are two material cart stations arranged vertically inside it; the vertical arrangement here is determined according to the orientation in the working state.

[0076] A fixing clamping device is used to fix and clamp the mobile material cart 3 onto the rotating body 2;

[0077] During operation, one of the mobile material carts 3 is initially located at the material cart station on the upper part of the rotating body 2, while the other mobile material cart 3, after receiving the material sheet on the material cart conveyor 4, is sent to the material cart station below the rotating body 2. At this time, the fixing and clamping device is activated to fix and clamp the two mobile material carts 3 inward. Then, under the drive of the first driving device 5, the rotating body 2 is rotated 180 degrees to complete the flipping of the material sheet. The material cart conveyor 4 then moves the mobile material cart 3 located at the lower station along with the material sheet out, thus completing one material sheet flipping process.

[0078] For the material car conveyor frame 4, in order to smoothly send the moving material car 3 into the rotating body 2, it is equipped with a second drive device 6, a conveyor belt 7 and a connecting piece 8; the second drive device 6 can be a motor, and the conveyor belt 7 can be a toothed belt.

[0079] The conveyor belt 7 is connected to the second drive device 6 in a transmission connection;

[0080] The connector 8 is fixed to the conveyor belt 7;

[0081] The end of the mobile material cart 3 is provided with a hook 9 that can move up and down;

[0082] When the mobile material cart 3 needs to be sent into or removed from the rotating body 2, the hook 9 is engaged with the connector 8. When the rotating body 2 performs a flipping action, the hook 9 is disengaged from the connector 8.

[0083] Specifically, such as Figure 2 , Figure 3 As shown, the end of the mobile material cart 3 is provided with a guide member 10, the hook 9 is provided with a guide rod 91, and the guide member 10 is provided with a guide hole that cooperates with the guide rod 91;

[0084] At the upper and lower positions of the material cart inlet / outlet 202, a third drive device 11 is respectively provided, which cooperates with the guide rod 91. Through the third drive device 11, the hook 9 can be driven to move upward, thereby realizing the disengagement action from the connecting piece 8. After disengagement, the moving material cart 3 can be freed from the constraint of the conveyor belt 7, and the rotating body 2 can rotate without interfering with other components. The third drive device 11 can be a hydraulic cylinder or a pneumatic cylinder.

[0085] The fixing and clamping device includes a fixing block 301 located at the bottom of the mobile material cart 3 and a locking cylinder 12 located on the rotating body 2; the fixing block 301 can be welded to the bottom of the mobile material cart 3 and can be a rectangular block structure.

[0086] The bottom of the fixing block 301 is provided with an insertion hole, and the end of the drive rod of the locking cylinder 12 is a ball joint 121. The ball joint 121 can be inserted into the insertion hole for fixing and locking under the action of the drive rod.

[0087] When the moving material cart 3 carrying the iron core sheet enters the rotating body 2, the locking cylinder 12 at the bottom lifts upwards, which can hold the iron core sheet between the upper and lower moving material carts 3, so that the sheet remains stable and does not slip during the flipping process. At the same time, the locking cylinder 12 at the top can hold the moving material cart 3 at the upper station, so that the upper moving material cart 3 will not fall.

[0088] In order to clamp and fix the moving material cart 3 at the upper and lower workstations, a preferred embodiment is that the fixing and clamping device further includes a fork 302, the end of which is a forked structure;

[0089] The bottom of the fixing block 301 is also provided with a sliding groove 3011 that is adapted to the fork 302, and the fork 302 can move freely in the sliding groove 3011;

[0090] The spherical joint 121 has a mating surface at its root that is adapted to the fork 302;

[0091] When the ball joint 121 is inserted into the insertion hole, the fork 302 moves along the slide groove 3011 toward the ball joint 121, and the two forked structures are inserted into the root of the ball joint 121, thus completing the locking and fixing between the moving material cart 3 and the rotating body 2.

[0092] The groove 3011 has a wedge-shaped, trapezoidal, or conical structure.

[0093] Each of the mobile material carts 3 is provided with four sets of fixing clamping devices, and the four sets of fixing clamping devices are arranged opposite each other in pairs along the width direction of the mobile material cart 3.

[0094] Each of the mobile material carts 3 also includes two sets of linkage drive devices 40 at its bottom. Each set of linkage drive devices 40 is used to drive a pair of forks 302 to simultaneously insert into and simultaneously remove from the ball joint 121.

[0095] For the linkage drive device 40, a preferred embodiment is that the device includes:

[0096] First end plate 401, first limiting rod 402, first driving rod 403, first connecting rod 404, intermediate connecting rod 405, swing rod 406, fixed shaft 407, mounting bracket 408, second end plate 409, second limiting rod 410, second driving rod 411, second connecting rod 412;

[0097] The first end plate 401 and the second end plate 409 are arranged opposite to each other along the width direction of the moving material cart 3; the first end plate 401 and the second end plate 409 are rectangular plate structures and are respectively movably connected to the two sides of the bottom of the moving material cart 3.

[0098] One end of the first limiting rod 402 is fixed to the inner side of the first end plate 401, and one end of the second limiting rod 410 is fixed to the inner side of the second end plate 409.

[0099] The first limiting rod 402 is a cylindrical structure with openings at both ends. The first end plate 401 has a through hole. The first driving rod 403 passes through the cylindrical structure and exits through the through hole. The first limiting rod 402 and the second limiting rod 410 can be square steel tubes, with the length set as needed. The first driving rod 403 and the second driving rod 411 are round steel.

[0100] The second drive rod 411 is hinged to the other end of the second limiting rod 410;

[0101] The two ends of the intermediate connecting rod 405 are fixedly connected to the ends of the first driving rod 403 and the second driving rod 411, respectively. The intermediate connecting rod 405 can be made of square steel tube or square steel, and its two ends are welded to the first driving rod 403 and the second driving rod 411 as a whole.

[0102] The intermediate connecting rod 405 has a through horizontal narrow hole 413 and a vertical narrow hole 414 in both the horizontal and vertical directions.

[0103] The fixed shaft 407 passes through the horizontal elongated hole 413 and is fixed to the mounting bracket 408, which is fixed to the bottom of the mobile material cart 3.

[0104] The swing arm 406 passes through the vertical narrow hole 414;

[0105] The middle part of the swing arm 406 is rotatably connected to the fixed shaft 407;

[0106] The horizontal narrow hole 413 and the vertical narrow hole 414 serve to prevent interference with the fixed shaft 407 when the intermediate connecting rod 405 moves left or right, and to allow the two ends of the swing rod 406 to swing freely, thereby enabling the transmission of force in the linkage mechanism.

[0107] The two ends of the first connecting rod 404 are respectively hinged to the first limiting rod 402 and one end of the swing rod 406;

[0108] The two ends of the second connecting rod 412 are respectively hinged to the other end of the second limiting rod 410 and the swing rod 406;

[0109] The first connecting rod 404, the swing rod 406 and the second connecting rod 412 form a "Z" shaped structure after installation;

[0110] The fork 302 is fixed to the inner side of the first end plate 401 and the second end plate 409 respectively;

[0111] When the second end plate 409 is pushed inward, the fork 302 fixed on the second end plate 409 moves inward. At the same time, the fork 302 located on the first end plate 401 also moves inward under the drive of the linkage mechanism.

[0112] When the first drive rod 403 is pushed inward, the first end plate 401 will be pushed outward, thereby causing the fork 302 mounted on the second mounting plate to move outward. At the same time, the fork 302 located on the first end plate 401 also moves outward under the drive of the linkage mechanism.

[0113] On the rotating body 2, a fourth driving device is provided at a position corresponding to the second end plate 409, for pushing the second end plate 409; a fifth driving device is provided at a position corresponding to the first driving rod 403, for pushing the first driving rod 403. Both the fourth and fifth driving devices can be hydraulic cylinders and pneumatic cylinders, respectively, and both only need to push the end plate and then retract during operation.

[0114] Specifically, the working process of the linkage drive device 40 mainly includes two processes: clamping and disengaging. Figure 8 The diagram illustrates the operating principle of the clamping process: When the moving material cart 3 enters the lower material cart position of the rotating body 2, the locking cylinder 12 inserts into the fixed block 301. Before the rotation begins, the fourth drive device is activated to push the second end plate 409. The second end plate 409 then drives the second limiting rod 410 to move. The second limiting rod 410 pushes the second drive rod 411 and the second connecting rod 412 to move simultaneously to the left. Since the fixed shaft 407 is fixed in position, a center point is formed. The first limiting rod 402 and the first drive rod 403 are in a nested relationship. Therefore, under the drive of the connecting rod formed by the first connecting rod 404, the second connecting rod 412, and the swing rod 406, the first connecting rod 404 pulls the first limiting rod 402 to move to the right, thereby causing the first end plate 401 to move to the right. Ultimately, this achieves the simultaneous inward movement of the two forks 302, inserting them into the ball joint 121 of the locking cylinder 12, thus forming a lock. Figure 9As shown, this is the principle of the disengagement action. After the rotating body 2 flips over, before the moving material cart 3 needs to be moved out, the fifth drive device pushes the first drive rod 403. At this time, the first drive rod 403 will drive the second limit rod 410 to the right through the intermediate connecting rod 405 and the second drive rod 411, and at the same time pull the second connecting rod 412 to the right. Then, through the swing rod 406 and the first connecting rod 404, the first connecting rod 404 will be pushed to the left, pushing the first limit rod 402 to the left, and finally realizing that the two forks 302 move to both sides at the same time, completing the action of disengaging the forks 302 from under the ball joint 121. At this time, the locking cylinder 12 can retract, and the moving material cart 3 can be moved out of the rotating body 2.

[0115] The pylon turning machine provided by this invention can turn over the iron chip pylon. At the same time, the ingenious structural design and small footprint greatly improve the turning efficiency, reduce the operator's workload and the damage to silicon steel sheets caused by turning.
