Description

Technical Field

[0001] The invention belongs to the technical field of unwinding racks, and in particular relates to a four-head unwinding rack for a silicon steel sheet transverse shearing line. Background Art

[0002] Silicon steel sheets generally refer to electrical steel, which is also called silicon steel sheets. They are a silicon-iron soft magnetic alloy with an extremely low carbon content. This material has good magnetic conductivity but poor electrical conductivity. Using silicon steel materials with poor electrical conductivity to make iron cores can avoid short circuits caused by closed circuits, which in turn cause circuit heating. Therefore, silicon steel sheets are widely used to make iron cores for various transformers, motors, and generators.

[0003] Shear-to-cross and shear-to-slitting lines are commonly used shearing methods in the production process of silicon steel sheets. Shear-to-cross refers to cutting silicon steel sheets horizontally according to certain specifications and sizes. The sheared silicon steel sheets can be used to make iron cores for motors and transformers.

[0004] At present, there is often a large amount of silicon steel coils cut from the longitudinal shearing line in the transformer core production workshop. The diameter of the silicon steel coils is large and the weight is also large. When loading at the cross-cutting line, the replacement of the silicon steel coils is basically dependent on manual lifting. Due to the instability of manual lifting and the low lifting accuracy, it takes a certain amount of time to complete the loading operation each time. In addition, the unloading rack used in the existing silicon steel sheet cross-cutting line can only hold one roll of sheet at a time. Each time it is used up and replaced, the machine must be stopped for replacement. Therefore, the continuity of production is affected and the labor intensity of workers is increased. In addition, during the feeding process, the diameter of the silicon steel coil decreases with the feeding process, so that the discharge speed of the reel after the diameter changes is inconsistent with the speed of the cross-cutting line flow loading, and during the feeding process, the silicon steel sheets may be bent due to accumulation in the buffer zone due to a large amount of spinning out. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a four-head unwinding rack for a silicon steel sheet transverse shearing line.

[0006] The technical solution adopted to solve the above technical problems is: a four-head unwinding rack for a silicon steel sheet transverse shearing line, comprising a supporting mechanism, the supporting mechanism comprising a supporting frame, a fixing frame is fixedly connected to the top of the supporting frame, a rotating replacement mechanism is installed on the top of the supporting mechanism, and a mounting fixing mechanism is fixedly connected to the top of the rotating replacement mechanism; A plurality of sets of automatic expansion and holding mechanisms are installed on the peripheral side of the installation and fixing mechanism, which are used to clamp and fix the silicon steel coil; An automatic lifting mechanism is installed between the supporting mechanism and the installation fixing mechanism, and a rotating material discharge mechanism is fixedly connected to the top of the automatic lifting mechanism; The rear end of the support mechanism is also provided with a coil lifting mechanism for lifting the silicon steel coil so as to cover the silicon steel coil on the corresponding automatic expansion and holding mechanism.

[0007] Furthermore, an inspection hole is provided at the front end of the support frame, so that the rotating replacement mechanism and the automatic lifting mechanism can be routinely maintained and inspected through the inspection hole.

[0008] Furthermore, the rotation replacement mechanism includes a first bearing installed on the outside of the fixed frame, and an inner gear ring is fixedly installed on the outside of the first bearing. A drive motor is installed on the inner surface of the top of the support frame, and a drive gear meshing with the inner gear ring is installed on the top of the output shaft of the drive motor.

[0009] Through the above technical solution, the inner gear ring, the top mounting and fixing mechanism and multiple groups of automatic expansion and holding mechanisms are driven by the driving motor to rotate, thereby changing the working positions of the four groups of automatic expansion and holding mechanisms. Specifically, when the silicon steel material coil at the working position is unloaded, the driving motor will start to work, thereby driving the driving gear to rotate synchronously through its output shaft. When rotating, the driving gear can drive the meshing inner gear ring to rotate 90 degrees, thereby rotating a group of automatic expansion and holding mechanisms at the adjacent position to the working position, thereby realizing the rapid and automatic replacement of the new material coil, which can greatly shorten the time required for material replacement.

[0010] Furthermore, the installation and fixing mechanism includes a fixing plate fixed on the top of the rotating replacement mechanism, a four-head bracket is fixedly connected to the top of the fixing plate, a top cover plate is fixedly connected to the top of the four-head bracket, and a plurality of corresponding through holes are opened on the inner circumference of the four-head bracket.

[0011] Through the above technical solution, the installation and fixing mechanism is used as an installation support structure, which is mainly used for the installation and fixing of four sets of automatic expansion and holding mechanisms. At the same time, under the rotation drive of the rotation replacement mechanism, the four-head bracket can drive the four sets of automatic expansion and holding mechanisms to rotate a certain angle according to the set program, thereby realizing the function of automatic material replacement.

[0012] Further, the automatic expansion mechanism includes a side mounting plate fixedly connected to the end of the mounting fixing mechanism, the outer side of the side mounting plate is fixedly connected to a mounting support, a second bearing is installed on the mounting support, an outer ring of the second bearing is fixedly installed, the outer side of the outer ring of the outer gear is fixedly connected to an inner mounting plate, a hollow shaft is fixedly connected to the outer center of the inner mounting plate, a plurality of groups of rectangular holes are provided on the circumference of the hollow shaft, an end fixing seat is fixedly installed on the other end of the hollow shaft, a limiting hole is provided in the middle of the end fixing seat, a clamping hydraulic cylinder is installed on the inner side of the side mounting plate, the telescopic end of the clamping hydraulic cylinder is fixedly connected to a first rotating connection assembly, the other end of the first rotating connection assembly is rotatably connected to a fixed shaft, a plurality of groups of first rotating supports are fixedly connected to the circumference of the outer wall of the fixed shaft, each of the first rotating supports is rotatably connected to a connecting rod, a plurality of arc expansion claws are provided on the outer side of the hollow shaft, two second rotating supports are provided on the inner side of each of the arc expansion claws, and the other end of each of the connecting rods is rotatably connected to the corresponding second rotating support.

[0013] Through the above technical scheme, the automatic expansion mechanism is mainly used for automatic clamping and fixing of silicon steel coils. When the operator sleeves the silicon steel coil on the outside of the multiple arc-shaped expansion claws, the piston rod of the clamping hydraulic cylinder will automatically extend outward, thereby synchronously driving the fixed shaft to slide in the limiting hole. During this process, the fixed shaft will also drive the multiple connecting rods to rotate, thereby synchronously driving the multiple arc-shaped expansion claws to expand outward until the multiple arc-shaped expansion claws clamp the inner hole of the silicon steel coil, thereby realizing the loading and fixing of the silicon steel coil; when the silicon steel coil at the working position is unloaded, the piston rod of the clamping hydraulic cylinder will automatically shrink, so that the multiple arc-shaped expansion claws will also automatically shrink inward at the same time, so that the coil shaft sleeve sleeved on the outside of the multiple arc-shaped expansion claws can be easily removed for subsequent replacement of new silicon steel coils; when the automatic expansion mechanism after loading is completed After the holding mechanism rotates to the working position, the automatic lifting mechanism will drive the rotary unloading mechanism to spirally descend, and make the unloading gear on the rotary unloading mechanism mesh with the outer gear ring. At this time, when the unloading gear rotates, it will drive the outer gear ring meshing with it to rotate, and the inner mounting plate, hollow shaft and other structures are fixed on the outer gear ring, so that the outer gear ring can drive the silicon steel coil to unload slowly. Since the telescopic end of the clamping hydraulic cylinder is connected to the fixed shaft through the first rotating connection component, the clamping hydraulic cylinder will not rotate with the silicon steel coil. In addition, under the speed control of the unloading motor, the unloading amount and tension of the coil can be controlled and adjusted to adapt to the process requirements of relatively stable output while the coil diameter changes. In the feeding process, it can effectively avoid the silicon steel sheets from being bent due to accumulation in the buffer zone due to a large number of rotations.

[0014] Furthermore, the number of each group of rectangular holes is two, and each connecting rod passes through the corresponding rectangular hole.

[0015] Through the above technical solution, the connecting rod passes through the corresponding rectangular hole, which not only facilitates the sliding of the connecting rod, but also the rectangular hole can limit the connecting rod.

[0016] Furthermore, the automatic lifting mechanism includes a first lifting hydraulic cylinder installed in the supporting frame and a limit seat fixedly installed at the top center of the supporting frame, the top end of the piston rod of the first lifting hydraulic cylinder is fixedly connected to the second rotating connection assembly, the top end of the second rotating connection assembly is rotatably connected to a rotating lifting shaft, the outer wall of the rotating lifting shaft is provided with two spiral grooves, a ball head bolt is threadedly connected to the outer wall of the limit seat, and the top end of the rotating lifting shaft is fixedly connected to a support block.

[0017] Through the above technical scheme, the automatic lifting mechanism is mainly used to drive the rotary unloading mechanism to perform spiral lifting. When the new silicon steel coil rotates to the loading position, the piston rod of the first lifting hydraulic cylinder will slowly contract, thereby driving the rotary lifting shaft to descend synchronously. At the same time, since the outer wall of the rotary lifting shaft is provided with two spiral grooves, and the ball head bolts threadedly connected on the outer wall of the limit seat are limited in the corresponding spiral grooves, the rotary lifting shaft will rotate along the two spiral grooves during the descent process under the limiting action of the two ball head bolts, so that the rotary unloading mechanism can realize rotary descent, and the unloading gear installed at the output end of the unloading motor can realize arc free cooperation with the outer gear ring, effectively avoiding the linear impact structure of the two gears, thereby extending the service life of the gears.

[0018] Furthermore, the rotary unloading mechanism includes a support plate fixed to the top of the automatic lifting mechanism, a unloading motor is installed on one side of the top front end of the support plate, and a unloading gear is installed at the output end of the unloading motor. The unloading gear can engage with the outer gear ring at the corresponding position in the working state.

[0019] Through the above technical scheme, the rotary unloading mechanism is mainly used to drive the automatic expansion and holding mechanism at the working position to rotate and unload. The four sets of automatic expansion and holding mechanisms are driven by only one unloading motor, which effectively reduces energy consumption and maintenance and operation costs. Specifically, when the new material coil is rotated into place, the support plate fixed on the top of the support block and the unloading motor will synchronously descend with the rotating lifting shaft. During the rotation and descent process, the unloading gear will slowly and freely cooperate with the outer gear ring to achieve circular arc, which can not only achieve safe and fast meshing, but also effectively avoid the collision of the two gears. During subsequent unloading, the unloading motor rotates by driving the unloading gear. The unloading motor adopts a servo reduction motor. The amount and tension of the coil can be controlled and adjusted under intelligent speed control, so as to further drive the silicon steel coil to perform stable automatic unloading.

[0020] Furthermore, the material roll lifting mechanism includes a lifting base, two lifting slide rails are provided on both sides of the inner wall of the lifting base, a lifting seat is slidably connected inside the lifting base, two corresponding lifting slide grooves are provided on both sides of the outer wall of the lifting seat, horizontal slide rails are fixedly installed on both sides of the top of the lifting seat, a horizontal slide is slidably connected between the two horizontal slide rails, a detachable material roll positioning seat is installed on the horizontal slide, handles are fixedly connected on both sides of the outer wall of the material roll positioning seat, and a second lifting hydraulic cylinder is installed on the top of the center of the lifting base, and the top of the piston rod of the second lifting hydraulic cylinder is in contact with the inner surface of the top of the lifting seat.

[0021] Through the above technical scheme, due to the heavy weight of the silicon steel coil, the traditional lifting method is used to directly and accurately put the silicon steel coil on the automatic expansion and holding mechanism, which is not only difficult to operate, but also very time-consuming and labor-intensive, and inefficient. By designing a coil lifting mechanism, in actual operation, the silicon steel coil can be first lifted by a lifting device and placed on the coil positioning seat, and then according to the position of the center hole, the piston rod of the second lifting hydraulic cylinder is controlled to lift the lifting seat upward. When the center hole of the silicon steel coil is roughly concentric with the axis of the automatic expansion and holding mechanism, the silicon steel coil can be pushed toward the automatic expansion and holding mechanism along two horizontal slide rails, and put on the outer wall of a plurality of arc-shaped expansion claws. After being placed in place, the second lifting hydraulic cylinder can be controlled to reset.

[0022] Furthermore, a circular arc-shaped positioning groove is provided on the top of the material roll positioning seat.

[0023] Through the above technical solution, the arc-shaped positioning groove can provide stable support and positioning for the rolled silicon steel material to prevent it from shaking or displacement during the loading process.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention adopts four sets of automatic expansion and holding mechanisms for replacement, thereby avoiding the phenomenon of multiple stops for feeding in the middle of the process, ensuring the continuity of production and improving work efficiency; at the same time, under the speed control of the driving motor, the uniformity and stability of the feeding is ensured, and the phenomenon of silicon steel sheets being easily bent during the feeding process is avoided; (2) The present invention adopts a spiral automatic lifting structure. Under the limiting action of two ball head bolts, the rotating lifting shaft rotates along two spiral grooves during the descent process, so that the discharge gear can freely cooperate with the outer gear ring in a circular arc, effectively avoiding the two The gears have a linear impact structure, thereby extending the service life of the gears; (3) The four-head unloading rack of the present invention has changed the disadvantage that traditional equipment requires four reducers to provide power separately. The four heads are driven by only one drive motor, which greatly reduces energy consumption and maintenance and operation costs. In addition, the equipment occupies a small area, which is convenient for the installation and layout of the equipment, and can also meet the requirements of automated intelligent production processes; (4) The present invention designs a material coil lifting mechanism, which can more conveniently and quickly put the silicon steel material coil on the automatic expansion and holding mechanism. Not only is the difficulty of operation greatly reduced, but the operation is also more time-saving and labor-saving, and the work efficiency is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-Figure 14 As shown, a four-head unloading rack for a silicon steel sheet transverse shearing line of the present embodiment includes a supporting mechanism 1, wherein the supporting mechanism 1 includes a supporting frame 101, a fixing frame 102 is fixedly connected to the top of the supporting frame 101, and an inspection hole 103 is opened at the front end of the supporting frame 101, so that the rotating replacement mechanism 2 and the automatic lifting mechanism 5 can be routinely maintained and inspected through the inspection hole 103.

[0029] like Figure 5-Figure 8As shown, a rotating replacement mechanism 2 is installed on the top of the support mechanism 1, and the rotating replacement mechanism 2 includes a first bearing 201 installed on the outside of the fixed frame 102, and an inner gear ring 202 is also fixedly installed on the outside of the first bearing 201. A driving motor 203 is installed on the inner surface of the top of the support frame 101, and a driving gear 204 meshing with the inner gear ring 202 is installed on the top of the output shaft of the driving motor 203. The inner gear ring 202 and the top mounting and fixing mechanism 3 and multiple groups of automatic expansion and holding mechanisms 4 are driven by the driving motor 203 to rotate, thereby changing the working positions of the four groups of automatic expansion and holding mechanisms 4. Specifically, when the silicon steel material coil at the working position is unloaded, the driving motor 203 will start to work, thereby driving the driving gear 204 to rotate synchronously through its output shaft. When rotating, the driving gear 204 can drive the inner gear ring 202 meshing therewith to rotate 90 degrees, thereby rotating a group of automatic expansion and holding mechanisms 4 at the adjacent position to the working position, thereby realizing rapid and automatic replacement of new material coils, thereby greatly shortening the time required for material replacement.

[0030] like Figure 5-Figure 8 As shown, the top of the rotary replacement mechanism 2 is fixedly connected with an installation and fixing mechanism 3, and the installation and fixing mechanism 3 includes a fixing plate 301 fixed on the top of the rotary replacement mechanism 2, and the top of the fixing plate 301 is fixedly connected with a four-head bracket 302, and the top of the four-head bracket 302 is fixedly connected with a top cover plate 303. The inner circumference of the four-head bracket 302 is provided with a plurality of corresponding through holes 304. The installation and fixing mechanism 3 serves as an installation support structure, and is mainly used for the installation and fixing of four groups of automatic expansion and holding mechanisms 4. At the same time, under the rotation drive of the rotary replacement mechanism 2, the four-head bracket 302 can drive the four groups of automatic expansion and holding mechanisms 4 to rotate a certain angle according to the set program, thereby realizing the function of automatic material replacement.

[0031] like Figure 1-Figure 11As shown, the peripheral side of the mounting and fixing mechanism 3 is equipped with multiple groups of automatic expansion and holding mechanisms 4, specifically four groups, and the automatic expansion and holding mechanisms 4 include a side mounting plate 401 fixedly connected to the end of the mounting and fixing mechanism 3, a mounting support 402 is fixedly connected to the outer side of the side mounting plate 401, a second bearing 403 is installed on the mounting support 402, an outer ring of the second bearing 403 is fixedly installed with an outer gear ring 404, an inner mounting plate 405 is fixedly connected to the outer side of the outer gear ring 404, a hollow shaft 406 is fixedly connected to the outer center of the inner mounting plate 405, and the peripheral side of the hollow shaft 406 A plurality of rectangular holes 407 are provided, an end fixing seat 408 is fixedly installed at the other end of the hollow shaft 406, a through-limiting hole 409 is provided in the middle of the end fixing seat 408, a clamping hydraulic cylinder 410 is installed on the inner side of the side mounting plate 401, a first rotating connection component 411 is fixedly connected to the telescopic end of the clamping hydraulic cylinder 410, a fixed shaft 412 is rotatably connected to the other end of the first rotating connection component 411, a plurality of first rotating supports 413 are fixedly connected to the outer wall circumference of the fixed shaft 412, and each first rotating support 413 is rotatably connected to the first rotating support 413. The hollow shaft 406 is connected to a connecting rod 414, and a plurality of arc-shaped expansion claws 415 are arranged on the outside of the hollow shaft 406. The inner side of each arc-shaped expansion claw 415 is provided with two second rotating supports 416. The other end of each connecting rod 414 is rotatably connected to the corresponding second rotating support 416. The automatic expansion mechanism 4 is mainly used for automatic clamping and fixing of the silicon steel coil. When the operator puts the silicon steel coil on the outside of the plurality of arc-shaped expansion claws 415, the piston rod of the clamping hydraulic cylinder 410 will automatically extend outward, thereby synchronously driving the fixed shaft 412 to slide in the limiting hole 409. During the process, the fixed shaft 412 will also drive the multiple connecting rods 414 to rotate, thereby synchronously driving the multiple arc-shaped expansion claws 415 to expand outward, until the multiple arc-shaped expansion claws 415 clamp the inner hole of the silicon steel coil, thereby realizing the loading and fixing of the silicon steel coil; when the silicon steel coil at the working position is unloaded, the piston rod of the clamping hydraulic cylinder 410 will automatically shrink, so that the multiple arc-shaped expansion claws 415 will also automatically shrink inward at the same time, so that the coil sleeves sleeved on the outer sides of the multiple arc-shaped expansion claws 415 can be easily removed, so as to replace the new silicon steel coil later; In this embodiment, when the automatic expansion mechanism 4 rotates to the working position after the loading is completed, the automatic lifting mechanism 5 will drive the rotary unloading mechanism 6 to spirally descend, and make the unloading gear 603 on the rotary unloading mechanism 6 mesh with the outer gear ring 404. At this time, when the unloading gear 603 rotates, it will drive the outer gear ring 404 meshing with it to rotate, and the inner mounting plate 405, the hollow shaft 406 and other structures are fixed on the outer gear ring 404, so that the outer gear ring 404 can drive the silicon steel coil to rotate. The material is discharged slowly. Since the telescopic end of the clamping hydraulic cylinder 410 is connected to the fixed shaft 412 through the first rotating connection component 411, the clamping hydraulic cylinder 410 will not rotate with the silicon steel coil. In addition, the discharge volume and tension of the coil can be controlled and adjusted under the speed control of the discharge motor 602 to adapt to the process requirements of relatively stable output volume while the coil diameter changes. During the feeding process, it can effectively avoid the silicon steel sheets from being bent due to accumulation in the buffer zone due to a large amount of rotation.

[0032] Furthermore, in this embodiment, the number of each group of rectangular holes 407 is two, and each connecting rod 414 passes through the corresponding rectangular hole 407 . The connecting rod 414 passing through the corresponding rectangular hole 407 not only facilitates the sliding of the connecting rod 414 , but also the rectangular hole 407 can limit the connecting rod 414 .

[0033] like Figure 4-Figure 13 As shown, an automatic lifting mechanism 5 is installed between the supporting mechanism 1 and the mounting and fixing mechanism 3. The automatic lifting mechanism 5 includes a first lifting hydraulic cylinder 501 installed in the supporting frame 101 and a limiting seat 502 fixedly installed at the top center of the supporting frame 101. The top end of the piston rod of the first lifting hydraulic cylinder 501 is fixedly connected with a second rotating connection component 503. The top end of the second rotating connection component 503 is rotatably connected with a rotating lifting shaft 504. The outer wall of the rotating lifting shaft 504 is provided with two spiral grooves 505. A ball head bolt 506 is threadedly connected on the outer wall of the limiting seat 502. The top end of the rotating lifting shaft 504 is fixedly connected with a supporting block 507. The automatic lifting mechanism 5 is mainly used to drive the rotating discharge mechanism 6 to perform spiral lifting. When the new silicon steel coil rotates to the loading position, After reaching the position, the piston rod of the first lifting hydraulic cylinder 501 will slowly contract, thereby driving the rotary lifting shaft 504 to descend synchronously. At the same time, since the outer wall of the rotary lifting shaft 504 is provided with two spiral grooves 505, and the ball head bolts 506 threadedly connected on the outer wall of the limiting seat 502 are limited in the corresponding spiral grooves 505, the rotary lifting shaft 504 is limited by the two ball head bolts 506. During the descent, it will rotate along the two spiral grooves 505, thereby enabling the rotary discharge mechanism 6 to realize rotary descent, and also enabling the discharge gear 603 installed at the output end of the discharge motor 602 to realize free arc cooperation with the outer gear ring 404, effectively avoiding the linear impact structure of the two gears, thereby extending the service life of the gears.

[0034] like Figure 1-Figure 3 As shown, the top of the automatic lifting mechanism 5 is fixedly connected with a rotating feeding mechanism 6, and the rotating feeding mechanism 6 includes a support plate 601 fixed to the top of the automatic lifting mechanism 5, and a feeding motor 602 is installed on one side of the front end of the top of the support plate 601, and a feeding gear 603 is installed on the output end of the feeding motor 602. The feeding gear 603 can mesh with the outer gear ring 404 at the corresponding position in the working state. The rotating feeding mechanism 6 is mainly used to drive the automatic expansion and holding mechanism 4 at the working position to rotate and discharge. The four groups of automatic expansion and holding mechanisms 4 are driven by only one feeding motor 602, thereby effectively reducing energy consumption and maintenance and operation costs. Specifically, when the new After the material coil is rotated into place, the support plate 601 fixed on the top of the support block 507 and the unloading motor 602 will descend synchronously with the rotating lifting shaft 504. During the rotation and descent process, the unloading gear 603 will slowly and freely cooperate with the outer gear ring 404 in a circular arc, which can not only achieve safe and fast meshing, but also effectively avoid the collision of the two gears. During subsequent unloading, the unloading motor 602 drives the unloading gear 603 to rotate. The unloading motor 602 adopts a servo reduction motor. The unloading amount and tension of the coil can be controlled and adjusted through intelligent speed control, so as to further drive the silicon steel coil to perform stable automatic unloading.

[0035] like Figure 2 and Fig.14As shown, a material coil lifting mechanism 7 is also provided at the rear end of the support mechanism 1 for lifting the silicon steel material coil so as to put the silicon steel material coil on the corresponding automatic expansion and holding mechanism 4. The material coil lifting mechanism 7 includes a lifting base 701. Two lifting slide rails 702 are provided on both sides of the inner wall of the lifting base 701. A lifting seat 703 is slidably connected inside the lifting base 701. Two corresponding lifting slide grooves 704 are provided on both sides of the outer wall of the lifting seat 703. Horizontal slide rails 705 are fixedly installed on both sides of the top of the lifting seat 703. A horizontal slide 706 is slidably connected between the two horizontal slide rails 705. A detachable material coil positioning seat 707 is installed on the horizontal slide 706. Handles 708 are fixedly connected on both sides of the outer wall of the material coil positioning seat 707. A second lifting hydraulic cylinder 709 is installed on the top of the center of the lifting base 701. The top end of the piston rod is in contact with the inner surface of the top of the lifting seat 703. Due to the heavy weight of the silicon steel coil, the traditional lifting method is used to directly and accurately put the silicon steel coil on the automatic expansion and holding mechanism 4. It is not only difficult to operate, but also very time-consuming and labor-intensive, and inefficient. By designing the coil lifting mechanism 7, in actual operation, the silicon steel coil can be first lifted and placed on the coil positioning seat 707 using a lifting device, and then, according to the position of the center hole, the piston rod of the second lifting hydraulic cylinder 709 is controlled to lift the lifting seat 703 upward. When the center hole of the silicon steel coil is roughly concentric with the axis of the automatic expansion and holding mechanism 4, the silicon steel coil can be pushed toward the automatic expansion and holding mechanism 4 along the two horizontal slide rails 705, and is put on the outer wall of the multiple arc-shaped expansion claws 415. After being placed in place, the second lifting hydraulic cylinder 709 can be controlled to reset.

[0036] In this embodiment, a circular arc positioning groove is further provided on the top of the coil positioning seat 707. The circular arc positioning groove can provide stable support and positioning for the rolled silicon steel coil to prevent it from shaking or displacement during the loading process.

[0037] Furthermore, the material coil lifting mechanism 7 can also be installed on both sides according to actual production needs or on-site layout requirements, and can be freely adjusted according to actual conditions; in addition, since the overall mass of the silicon steel coil is heavy, in order to further reduce the workload of operators, an automatic propulsion mechanism can also be designed on the lifting seat 703, so that the silicon steel coil can be pushed to the designated position instead of manually.

[0038] Furthermore, in this embodiment, the four-head unloading rack of the present invention changes the disadvantage that the traditional equipment needs four reducers to provide power separately, and the equipment occupies a small area, which is convenient for the installation and layout of the equipment, and can also realize the requirements of automated intelligent production process.

[0039] The working principle of this embodiment is as follows: when the silicon steel coil at the working position is unloaded, the first lifting hydraulic cylinder 501 will drive the rotary unloading mechanism 6 to spirally rise, so that the unloading gear 603 and the corresponding outer gear ring 404 are slowly separated. After the rotary unloading mechanism 6 rises to the specified position, it sends a signal to the information processing center, and the information processing center provides instructions to the rotary replacement mechanism 2, and the rotary replacement mechanism 2 starts to rotate, thereby driving a group of automatic expansion and holding mechanisms 4 at adjacent positions and the new silicon steel coil to rotate to the working position; After the new silicon steel coil is rotated into place, the automatic lifting mechanism 5 will drive the rotary unloading mechanism 6 to spirally descend, and make the unloading gear 603 on the rotary unloading mechanism 6 mesh with the outer gear ring 404. When the unloading gear 603 rotates, it will drive the meshing outer gear ring 404 to rotate, so that the outer gear ring 404 can drive the silicon steel coil to be unloaded slowly; During the unloading process, the operator can use the coil lifting mechanism 7 at the rear of the equipment to prepare new coils. When working, the silicon steel coil can be hoisted by the hoisting device and placed on the coil positioning seat 707, and then the piston rod of the second lifting hydraulic cylinder 709 is controlled to lift the lifting seat 703 upward according to the position of the center hole. When the center hole of the silicon steel coil is roughly concentric with the axis of the automatic expansion and holding mechanism 4, the silicon steel coil can be pushed toward the automatic expansion and holding mechanism 4 along the two horizontal slide rails 705, and the outer wall of the multiple arc expansion claws 415 is sleeved. By replacing the four groups of automatic expansion and holding mechanisms 4, the original phenomenon of multiple stops for loading is effectively avoided, ensuring the continuity of production and improving work efficiency.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
