Description

Technical Field

[0001] The invention relates to the technical field of transformer production equipment, and in particular to a core plate forming production line. Background Art

[0002] In the existing processing and production, the iron core steel plate of the transformer adopts the cold rolling production process, which requires the raw steel strip to be wound into a coil of a specific diameter, and then the coil is cold rolled to obtain the finished iron core steel plate.

[0003] In the prior art, the production of core steel plates is still achieved through manual operation of corresponding equipment. Since the steel strip raw materials and the formed core steel plates are very heavy, manual operation is often very dependent on cranes, the production threshold is high, and there are also problems such as low production efficiency and great safety hazards.

The steel strip coil can be supported on the material supporting plate, which is convenient for transferring to the rolling platform for pressing processing. The core plate forming production line of the present invention realizes the winding of the steel strip coil by the winding device, and then removes the steel strip coil from the winding device and flips it to be flush with the rolling platform by the material moving device, and then transfers it to the rolling device for pressurized rolling and forming, thereby avoiding manual material handling or crane material handling and greatly improving production efficiency.

[0035] Reference Figures 1 to 8 The core board forming production line of the present invention makes the following embodiments:

[0036] A core plate forming production line includes: a winding device 100, a rolling device 200 and a material moving device 300.

[0037] The winding device 100 is used to wind the steel strip material into a coil of a preset diameter. In this embodiment, the winding device 100 includes a winding turntable 110 and a winding drive member. The winding turntable 110 is in the shape of a disk, and the rotation axis of the winding turntable 110 extends in the left-right direction.

[0038] The winding device 100 and the material transfer device 300 are arranged on the left and right sides, and the winding turntable 110 has a plurality of winding blocks 120 on one side facing the material transfer device 300. The plurality of winding blocks 120 are distributed around the circumference of the winding turntable 110.

[0039] The rolling device 200 and the material transfer device 300 are arranged front and back, and the rolling device 200 has a rolling platform 210 extending front and back. The left and right sides of the rolling platform 210 are respectively provided with a forming rib and a forming block 220, and the forming rib is fixedly arranged on the rolling platform 210. The rolling device 200 includes an extrusion driving member 230 for driving the forming block 220 to move left and right relative to the forming rib.

[0040] The material transfer device 300 includes: a translation frame 310 , a translation driving mechanism, a flip frame 330 , a flip driving mechanism 340 and a material transfer clamping mechanism 350 .

[0041] The flip frame 330 has a rotation axis extending forward and backward. The flip frame 330 has a material support plate 331 extending forward and backward. The material support plate 331 is flush with the rolling platform 210 when perpendicular to the up and down direction. A plurality of material transfer clamp mechanisms 350 are distributed on the material support plate 331 along a circular path. The material transfer clamp mechanism 350 has a material clamping part that can be opened and closed.

[0042] The flip frame 330 is rotatably connected to the translation frame 310, and the flip driving mechanism 340 is used to drive the flip frame 330 to rotate relative to the translation frame 310. The translation frame 310 is slidably arranged in the left and right directions, and the translation driving mechanism is used to drive the translation frame 310 to move left and right relative to the winding device 100.

[0043] During actual use, the winding turntable 110 rotates, and the steel strip material is wound into an annular steel strip coil by a plurality of the winding clamping blocks 120. The flipping drive mechanism 340 drives the flipping frame body 330 to rotate, so that the material supporting plate body 331 is flipped to a vertical state. The material supporting plate body 331 is parallel to and oppositely arranged with the winding turntable 110. The translation drive mechanism drives the translation frame body 310 to move towards the winding device 100, so that the material supporting plate body 331 approaches the winding turntable 110. After a plurality of the material shifting clamping mechanisms 350 clamp various parts of the steel strip coil, the translation drive mechanism drives the flipping frame body 330 to move away from the winding turntable 110, and the material supporting plate body 331 is flipped to be flush with the rolling platform 210 through the flipping drive mechanism 340, so as to realize the material taking after the steel strip coil is wound. The steel strip coil can be supported on the material supporting plate body 331, which is convenient for being transferred to the rolling platform 210 for pressing processing.

[0044] In this embodiment, the winding clamping blocks 120 are arranged on the right side of the winding turntable 110, the material shifting device 300 is arranged on the right side of the winding device 100, and the rolling device 200 is arranged in front of the material shifting device 300.

[0045] The left side of the translation frame body 310 has an avoidance opening. In the projection in the up-and-down direction, the translation frame body 310 is in an inverted "C" shape. The front and rear dimensions of the avoidance opening are larger than those of the winding device 100. When the translation frame body 310 moves leftward, the avoidance opening of the translation frame body 310 can avoid the winding device 100, preventing obstruction and interfering with the material taking of the steel strip coil.

[0046] Both the front and rear ends of the flipping frame body 330 are provided with flipping guide rings 333 in a circular ring shape. The flipping drive mechanism 340 includes a guide wheel group. The guide wheel group is arranged in pairs in the front and rear of the translation frame body 310. The guide wheel group includes a plurality of flipping guide wheels 341 arranged along an annular path. Both axial ends of the flipping guide wheel 341 have guide flanges. The two flipping guide rings 333 are correspondingly arranged with the guide wheel group. The plurality of flipping guide wheels 341 arranged along the annular path are all in rolling contact with the flipping guide rings 333, and the guide rings are embedded between the two guide baffles.

[0047] The flipping drive mechanism 340 further includes a flipping drive motor 342. The flipping drive motor 342 is drivingly connected to one of the flipping guide wheels 341.

[0048] Furthermore, the flip frame 330 has a first limit plate and a second limit plate, and the translation frame 310 has a first positioning plate 311 and a second positioning plate. The first limit plate and the second limit plate are both arranged at the outer edge of the flip range of the flip frame 330, and the first positioning plate 311 and the second positioning plate are fixedly connected to the translation frame 310. When the support plate 331 is flush with the rolling platform 210, the first limit plate abuts against the first positioning plate 311. When the support plate 331 is parallel to the winding turntable 110, the second limit plate abuts against the second positioning plate.

[0049] The translation drive mechanism includes a base frame 320, a translation drive motor, a drive rack and a drive gear. The translation frame 310 is slidably mounted on the base frame 320 in the left-right direction, and the drive rack extends in the left-right direction and is fixedly mounted on the base frame 320. The drive gear is rotatably mounted on the translation frame 310 and meshes with the drive rack. The translation drive motor is drivingly connected to the drive gear.

[0050] There are four material transfer clamp mechanisms 350, which are respectively arranged at the front and rear ends and the left and right ends of the annular path. When the winding turntable 110 is taken out, the upper and lower ends and the front and rear ends of the steel strip coil are clamped by the four material transfer clamp mechanisms 350, so that the steel strip coil can be disengaged from the winding clamp block 120 as the turning frame 330 moves to the right.

[0051] In order to prevent the stroke of the forming block 220 from being too large, the distance between the forming rib and the forming block 220 is generally smaller than the diameter of the steel strip coil. In order to facilitate the transfer of the steel strip coil from the support plate 331 to the rolling platform 210, the steel strip coil needs to be compressed and deformed in the left and right directions when entering the rolling platform 210.

[0052] The two material moving clamp mechanisms 350 disposed at the front and rear ends are respectively a front material moving clamp 351 and a rear material moving clamp 352. The front material moving clamp 351 and the rear material moving clamp 352 are disposed front and rear and are connected to the flip frame 330 for front and rear sliding movement. The material moving device 300 also includes a clamp driving mechanism 360 for driving the front material moving clamp 351 and the rear material moving clamp 352 to move toward or away from each other along the front and rear direction.

[0053] After the steel strip coil is flipped over with the supporting plate 331 to be flush with the rolling platform 210, the clamp driving mechanism 360 drives the front clamp 351 and the rear clamp 352 to move away from each other in the front-to-back direction, thereby increasing the distance between the front and rear ends of the steel strip coil, and the steel strip coil is extended forward and backward and narrowed left and right.

[0054] The flip frame 330 is provided with two first clamping slides 335 for sliding along the front-back direction. The two first clamping slides 335 are arranged front and back. The front material clamp 351 and the rear material clamp 352 are respectively installed on the two first clamping slides 335.

[0055] The clamping drive mechanism 360 includes a material moving drive motor 361 and a screw nut drive component 362. The two first clamping slides 335 are driven by corresponding screw nut drive components 362. The material moving drive motor 361 is connected to the screw nut drive component 362 to realize the linear drive of the first clamping slide 335.

[0056] In some other embodiments, the clamping drive mechanism 360 may also adopt a bidirectional drive screw. The axial direction of the bidirectional drive screw extends in the front-to-back direction, and the front half and the rear half of the bidirectional drive screw have opposite thread rotation directions. The output shaft of the material shifting drive motor 361 is connected to the bidirectional drive screw in a driving manner. The two first clamping slides 335 are connected to the bidirectional drive screw in a threaded manner with opposite thread rotation directions.

[0057] When the material shifting drive motor 361 drives the bidirectional drive screw to rotate, the two first shifting clamp slides 335 approach each other or move away from each other in the front-to-back direction, so that the front material clamp 351 and the rear material clamp 352 can be aligned with the front and rear ends of the steel strip coil to achieve material picking, and can also stretch the steel strip coil on the supporting plate 331 to facilitate subsequent pressurization and rolling.

[0058] In some other embodiments, the clamp-shifting driving mechanism 360 may also be in the form of a motor-driven synchronous belt component. Two synchronous pulleys are arranged front and back, and the synchronous pulleys are driven by the motor to rotate, so that the synchronous belts wound around the two synchronous pulleys can move along a closed loop path. The two first clamp-shifting slides 335 are respectively connected to the left and right sides of the synchronous belt to achieve forward and backward reverse movement.

[0059] The other two material moving clamp mechanisms 350 are respectively a left material moving clamp 353 and a right material moving clamp 354. The left material moving clamp 353 and the right material moving clamp 354 are slidably arranged on the perpendicular bisector of the connecting line of the front material moving clamp 351 and the rear material moving clamp 352. The clamp moving driving mechanism 360 is transmission-connected with the left material moving clamp 353 and the right material moving clamp 354, and makes the two move toward each other or away from each other along the perpendicular bisector of the front material moving clamp 351 and the rear material moving clamp 352.

[0060] In this embodiment, the flip frame 330 is provided with two second clamping slides 336 for sliding along the left and right directions. The two second clamping slides 336 are arranged on the perpendicular bisector of the connection line of the two first clamping slides 335, and the left material clamp 353 and the right material clamp 354 are respectively installed on the two second clamping slides 336.

[0061] The clamping drive mechanism 360 includes four transmission connecting rods 363. The four transmission connecting rods 363 are respectively arranged between the forward material clamp 351, the left material clamp 353, the rear material clamp 352 and the right material clamp 354. The forward material clamp 351, the left material clamp 353, the rear material clamp 352 and the right material clamp 354 are all transmission-hinged with the ends of two of the transmission connecting rods 363, and the four transmission connecting rods 363 form a parallelogram connecting rod structure. When the forward material clamp 351 and the rear material clamp 352 move away from each other, the left material clamp 353 and the right material clamp 354 move toward each other, so that the left and right sides of the steel strip material coil are narrowed and the front and rear sides are elongated, and the circular ring shape is changed into an approximately elliptical ring shape.

[0062] In some other embodiments, the two first clamping slides 335 and the two second clamping slides 336 can be driven to move forward and backward by a linear driving component such as a cylinder, an electric push rod, a hydraulic push rod, or a screw nut driving assembly.

[0063] When the steel strip coil is transferred from the supporting plate 331 to the rolling platform 210, in order to avoid the material clamping part from obstructing the steel strip coil, it is preferred that the material shifting clamp mechanism 350 can be telescopically moved in a direction perpendicular to the supporting plate 331. In this embodiment, the supporting plate 331 has a clamping avoidance hole 332. The material shifting clamp mechanism 350 is disposed in the clamping avoidance hole 332. The material shifting clamp mechanism 350 includes a telescopic driving member 356. The telescopic driving member 356 is used to drive the clamping part to move relative to the flip frame 330 in a direction perpendicular to the supporting plate 331.

[0064] Specifically, the material shifting clamp mechanism 350 includes: a material clamping member 355 and the telescopic driving member 356. The material clamping member 355 includes a material clamping cylinder and a material clamping piece. The material clamping pieces are arranged in pairs facing each other, and the material clamping cylinder is used to drive the paired material clamping pieces to press against or open each other to form the material clamping part. The telescopic driving member 356 is a telescopic cylinder, and the cylinder body of the telescopic driving member 356 is connected to the first clamping slide 335 or the second clamping slide 336, and the piston rod of the telescopic driving member 356 is connected to the material clamping member 355.

[0065] When the telescopic driving member 356 extends upward, the clamping part can extend from the lower side of the supporting plate 331 to the upper side, so as to obtain the material from the winding device 100. When the steel strip coil needs to be transferred from the supporting plate 331 to the rolling platform 210, the telescopic driving member 356 is reset downward, so that the clamping part is retracted to the lower side of the supporting plate 331, which will not hinder the movement of the steel strip coil.

[0066] In order to prevent the steel strip coil from being stuck on the winding clamp 120 and being difficult to disengage, the winding device 100 is provided with a diameter-changing driving mechanism 130 for driving the winding clamp 120 to slide radially along the winding turntable 110 .

[0067] In this embodiment, the variable diameter driving mechanism 130 includes: a variable diameter driving unit 131 , a variable diameter driving shaft 132 and a variable diameter screw 133 .

[0068] There are multiple reducing screws 133. The reducing screws 133 are arranged in a one-to-one correspondence with the winding blocks 120. The reducing screws 133 extend in the radial direction of the winding turntable 110. The reducing screws 133 are rotationally connected with the winding turntable 110. The winding blocks 120 are threadedly connected with the reducing screws 133 in a one-to-one correspondence. The reducing drive shaft 132 is coaxially rotatably arranged in the middle of the winding turntable 110. The reducing drive unit 131 is used to drive the reducing drive shaft 132 to rotate relative to the winding turntable 110.

[0069] The ends of the plurality of variable diameter screws 133 extend to the middle of the winding turntable 110 and are synchronously connected to the variable diameter drive shaft 132. Specifically, the variable diameter drive shaft 132 extends left and right, and the variable diameter screws 133 are perpendicular to the variable diameter drive shaft 132. The variable diameter drive shaft 132 and the variable diameter screws 133 are synchronously connected by bevel gears that mesh with each other. The variable diameter drive unit 131 can use a rotating drive element such as a servo motor, a stepper motor or a pneumatic motor, and the output shaft is fixedly connected to the variable diameter drive shaft 132 or is connected by a belt drive, a chain drive, a gear drive or a worm gear drive.

[0070] After the winding is completed, the flip frame 330 drives the four material transfer clamp mechanisms 350 to clamp the steel strip material coil, and the variable diameter drive unit 131 drives the variable diameter drive shaft 132 to rotate, synchronously drives the multiple variable diameter screws 133 to rotate, and drives the winding clamp block 120 to move along the radial direction of the winding turntable 110 through thread transmission. The multiple winding clamp blocks 120 move synchronously along the radial direction toward the middle of the winding turntable 110 to loosen the steel strip material coil, making it convenient for the material transfer clamp mechanism 350 to take the material.

[0071] It is worth noting that in order to avoid interference and collision during the material picking process, when the material transfer clamp mechanism 350 moves toward the winding device 100, the winding block 120 and the material transfer clamp mechanism 350 are staggered from each other in the left and right directions, and the material transfer clamp mechanism 350 is aligned with the area between two adjacent winding blocks 120.

[0072] Furthermore, in order to pull the steel strip coil from the support plate 331 to the rolling platform 210, the rolling device 200 includes a material pulling mechanism. The material pulling mechanism includes: a material pulling piece, a lifting drive component and a material pulling drive component. The material pulling piece is arranged above the rolling platform 210. The lifting drive component is used to drive the material pulling piece to move up and down relative to the rolling platform 210, and the material pulling drive component is used to drive the material pulling piece to move forward and backward.

[0073] In this embodiment, the material pulling member is in the shape of a cylinder extending up and down. In actual use, the material pulling driving member drives the material pulling member to move above the steel strip coil of the material supporting plate 331, and after the lifting driving member drives the material pulling member to extend downward into the inner side of the steel strip coil, the material pulling driving member drives the material pulling member to move forward, and the steel strip coil is pulled onto the rolling platform 210 through the material pulling member.

[0074] The lifting drive component is a linear drive component such as a cylinder, an electric push rod, a hydraulic push rod or a screw nut drive assembly arranged in the up and down directions.

[0075] Furthermore, the edge of the support plate 331 has a material guide rib. The material guide rib protrudes from the support plate 331, and can limit the steel strip coil to prevent the steel strip coil from extending out of the support plate 331. The support plate 331 is provided with a material guide outlet at one end facing the rolling device 200. Both sides of the material guide outlet are provided with material guide components 334. The material guide component 334 includes a plurality of guide wheels arranged in an array. The distance between the two material guide components 334 is narrow in front and wide in the back.
