Description

Technical Field

[0001] This invention relates to the field of transformer core manufacturing technology, and in particular to a core stacking device used in the production of dry-type transformer cores. Background Technology

[0002] Commonly used transformer cores are generally made of silicon steel sheets. During the manufacturing process, multiple silicon steel sheets need to be stacked according to a predetermined path, which requires a stacking device.

[0003] Existing core stacking devices typically involve stacking multiple layers of silicon steel sheets to form a multi-layered core structure, thus creating the core product required for transformers. For example, CN202111297016.X provides a core stacking device for dry-type transformer core manufacturing, relating to the field of dry-type transformer core manufacturing technology. This device solves the problem that existing stacked silicon steel sheets are difficult to non-mechanically limit the lowest silicon steel sheet. However, the path block structure used in the above technology, which is narrow at both ends and wide in the middle, is insufficient for clamping and limiting cores of various types due to the different core models, thus hindering the accuracy and flexibility of processing. Therefore, we propose a core stacking device for dry-type transformer core manufacturing to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a core stacking device for dry-type transformer core manufacturing. This device primarily utilizes fixed inserts and bolt pads to centrally insert and fix silicon steel sheets. A threaded strip is driven by an end handle to move within the threaded groove, causing a moving plate and damping mechanism to move the center plate to a suitable clamping position. The center plate and vertically distributed rubber strips then conform to the sides of the silicon steel sheets. Next, two sets of first lifting blocks on the side groove plates, along with side support blocks connected to adjusting bolts, firmly adhere and fix the outer ends of the silicon steel sheets. This provides adaptive limiting and fixing for cores of various construction types, ensuring the processing accuracy of dry-type transformer core manufacturing.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 In this embodiment of the invention, a core stacking device for manufacturing dry-type transformer cores includes a base assembly 1 and a stacking mechanism 4. The inner top side of the base assembly 1 is provided with a bolt-assembled mounting component 2, the outer sides of both ends of the base assembly 1 are provided with bolt-assembled limiting mechanisms 3, and the upper two sides of the base assembly 1 are provided with stacking mechanisms 4.

[0029] The base assembly 1 includes a pressure-reducing pad 101, a cabinet 102, and a grooved platform 103. The cabinet 102 is provided on the top side of the pressure-reducing pad 101, and the grooved platform 103 is provided on the top side of the cabinet 102. The grooved platform 103 has an inner bottom and an outer height structure.

[0030] In an embodiment of the present invention, the equipment is placed on a flat processing location using a pressure-reducing pad 101 and a cabinet 102, and the mounting component 2, the limiting mechanism 3 and the stacking mechanism 4 are assembled sequentially using a slotted platform 103 provided on the top side of the cabinet 102.

[0031] The mounting component 2 includes a bolt base 201, a shock-absorbing pad 202, a lower insert plate 203, an upper connecting plate 204, a bolt pad 205, and a fixing rod 206. The bolt base 201 is located on the inner top side of the slotted platform 103. The shock-absorbing pad 202 is located above the bolt base 201, and the lower insert plate 203 is located on the top side of the shock-absorbing pad 202. The upper connecting plate 204 is bolted to the top side of the lower insert plate 203, and the fixing rod 206 is bolted to the top side of the upper connecting plate 204 through the bolt pad 205.

[0032] In the embodiments of the present invention, during the stacking process, since the lower insert plate 203 is connected to the bolt base 201 through the shock-absorbing pad 202, the shock-absorbing pad 202 can absorb and diffuse the vibration force generated by stacking, improve the stacking accuracy, and avoid damage to the equipment caused by the vibration force. After the stacking is completed, the iron core is removed by the upper connecting plate 204 in conjunction with the fixing rod 206 for the next stage of stacking.

[0033] The limiting mechanism 3 includes a bolt seat 301, an end side plate 302, a threaded groove 303, an end handle 304, a threaded strip 305, a movable piece 306, a shock-absorbing damper 307, a center plate 308, a rubber strip 309, a side groove plate 3010, a first lead screw 3011, a first lifting block 3012, a bolt connecting block 3013, and a side support block 3014. The end side plate 302 is bolted to the outer sides of both ends of the grooved platform 103 through the bolt seat 301. The inner side of the end side plate 302 is provided with a threaded groove 303, and the inner side of the threaded groove 303 is threadedly connected to the threaded strip 305 for installing the end handle 304.

[0034] In an embodiment of the present invention, during the palletizing process, the adjusting end handle 304 outputs power to drive the threaded bar 305 on the inner side of the threaded groove 303 to run, so that the movable piece 306 provided at one end of the threaded bar 305 moves to the clamping and fixing position.

[0035] One end of the threaded strip 305 is provided with a movable piece 306, and the inner side of the movable piece 306 is provided with a shock-absorbing damper 307. One side of the shock-absorbing damper 307 is provided with a center plate 308, and the inner side of the center plate 308 is attached with a rubber strip 309.

[0036] In the embodiments of the present invention, when the threaded bar 305 drives the movable piece 306 to the clamping and fixing position, the stacking mechanism 4 and the mounting component 2 can absorb and diffuse the vibration force generated by the descent of the iron core through the rubber strip 309 provided on one side of the center plate 308 when stacking the products, thus avoiding the effect of vibration force on the stacking instability of the iron core.

[0037] A side groove plate 3010 is provided on the outer side of the center plate 308, and a first lead screw 3011 is provided inside the side groove plate 3010. The first lead screw 3011 is threadedly connected to a first lifting block 3012, and a side support block 3014 is bolted to one side of the first lifting block 3012 through a bolt connecting block 3013.

[0038] In an embodiment of the present invention, when the iron core is stacked higher, the first lead screw 3011 outputs power to drive the first lifting block 3012 to adjust to the optimal height in sequence. The side support block 3014, which is bolted to the first lifting block 3012 by the bolt connecting block 3013, limits and fixes the iron core set on the mounting component 2, so as to improve the stability of the iron core stacking and the number of stacking layers.

[0039] The palletizing mechanism 4 includes a horizontal compartment 401, a gearbox 402, a first motor 403, a transverse lead screw 404, a slider 405, a straight slot frame 406, a top rod 407, a second motor 408, a sensor probe 409, a second lead screw 4010, a second lifting block 4011, an electric articulated seat 4012, a first boom 4013, a second boom 4014, a swing arm 4015, and a pneumatic clamp 4016. The horizontal compartment 401 is bolted to the upper two sides of the slotted platform 103. One end of the horizontal compartment 401 is provided with a gearbox 402 connected to the output end of the first motor 403, and the output end of the gearbox 402 passes through the horizontal compartment 401 and is connected to the transverse lead screw 404. The transverse lead screw 404 is threadedly connected to the slider 405.

[0040] In an embodiment of the present invention, during use, the first motor 403 is started to output power to drive the output end of the first motor 403 to run. After the output end of the first motor 403 outputs power, the speed is changed through the gearbox 402, so that the power drives the transverse lead screw 404 inside the transverse chamber 401 to run. The transverse lead screw 404 drives the slider 405 to the processing location. At this time, the sensing probe 409 below the top rod 407 senses the location of material picking.

[0041] The outer end of the slider 405 is provided with a straight groove frame 406, and the top of the straight groove frame 406 is provided with a bolt-connected top rod 407. A second motor 408 is provided above both ends of the top rod 407, and an array of sensing probes 409 are provided on the inner bottom side of the top rod 407.

[0042] In an embodiment of the present invention, after reaching the material picking location, the second motor 408 is started to output power to drive the second lead screw 4010 inside the straight groove frame 406 to run, so that the second lead screw 4010 drives the second lifting block 4011 to the material picking height. Then, the electric hinge seat 4012 is started to output power to drive the first boom 4013 to run, so that the first boom 4013 drives the second boom 4014 to a suitable position. The operation of the second boom 4014 drives the swing arm 4015 to run to the material picking location. When the swing arm 4015 runs to the material picking location, the pneumatic clamp 4016 at one end of the swing arm 4015 is used to clamp the iron core.

[0043] The output end of the second motor 408 is connected to the top rod 407 and the straight groove frame 406 by a second lead screw 4010, and the second lead screw 4010 is threadedly connected to a second lifting block 4011. An electric hinge seat 4012 is provided on one side of the second lifting block 4011, and a first boom 4013 is provided on one side of the electric hinge seat 4012. A second boom 4014 is provided at one end of the first boom 4013, and a swing arm 4015 for mounting a pneumatic clamp 4016 is provided at one end of the second boom 4014.

[0044] In an embodiment of the present invention, after the pneumatic clamp 4016 clamps the iron core, the first motor 403 is started to output power to drive the output end of the first motor 403 to run, so that the transverse lead screw 404 drives the slider 405 to the stacking position. At this time, the second motor 408 outputs power to drive the second lead screw 4010 inside the straight slot frame 406 to run, so that the second lead screw 4010 drives the second lifting block 4011 to the stacking height. Then, the electric hinge seat 4012 outputs power to drive the first boom 4013 to run, so that the first boom 4013 drives the second boom 4014 to a suitable position. Through the adjustment of the second lifting block 4011 by the second lead screw 4010, the iron core is inserted into the fixing rod 206 set on the bolt pad 205 to achieve the effect of stacking layer by layer.

[0045] The working principle of this invention is as follows: In use, the first motor 403 is started, outputting power to drive the output end of the first motor 403. After the output end of the first motor 403 outputs power, the speed changes through the gearbox 402, causing the power to drive the transverse lead screw 404 inside the transverse chamber 401. The transverse lead screw 404 drives the slider 405 to the processing location. At this time, the sensing probe 409 below the top rod 407 senses the material picking location. After reaching the material picking location, the second motor 408 is started, outputting power to drive the second lead screw 4010 inside the straight groove frame 406. The second lead screw 4010 drives the second lifting block 4011 to the material picking height. Then, the electric articulation seat 4012 is started, outputting power to drive the first boom 4... Operation 013 initiates the process, causing the first boom 4013 to drive the second boom 4014 to a suitable position. The movement of the second boom 4014 then drives the swing arm 4015 to the material-collecting location. Once the swing arm 4015 reaches the location, a pneumatic clamp 4016 at one end of the swing arm 4015 clamps the iron core. After the pneumatic clamp 4016 clamps the iron core, the first motor 403 is activated, outputting power to drive its output end. This causes the transverse lead screw 404 to drive the slider 405 to the stacking position. At this time, the second motor 408 outputs power to drive the second lead screw 4010 inside the straight slot frame 406, causing the second lead screw 4010 to drive the second lifting block 4011 to the stacking position. The height is then adjusted by using the electric articulation seat 4012 to drive the first boom 4013, which in turn drives the second boom 4014 to a suitable position. The second lead screw 4010 adjusts the second lifting block 4011, allowing the iron core to be inserted into the fixed insert 206 on the bolt pad 205 to achieve a layered stacking effect. During stacking, the adjusting handle 304 outputs power to drive the threaded strip 305 on the inner side of the threaded groove 303, causing the movable piece 306 at one end of the threaded strip 305 to move to the clamping and fixing position. Once the threaded strip 305 has driven the movable piece 306 to the clamping and fixing position, the stacking mechanism 4 and the mounting component 2 stack the products. The vibration force generated by the descent of the iron core can be absorbed and diffused by the rubber strip 309 on one side of the center plate 308, avoiding the unstable stacking effect caused by the vibration force. When the iron cores are stacked, the first lead screw 3011 outputs power to drive the first lifting block 3012 to adjust to the optimal height in sequence. The side support block 3014, which is bolted to the first lifting block 3012 by the bolt connecting block 3013, limits and fixes the iron cores set on the mounting component 2, thereby improving the stability of the iron core stacking and the number of stacked layers. During the stacking process, since the lower insert plate 203 is connected to the bolt base 201 through the shock-absorbing pad 202, the shock-absorbing pad 202 can absorb and diffuse the vibration force generated by the stacking, improving the stacking accuracy.To avoid damage to the equipment from vibration, after stacking is complete, the iron core is removed using the upper connecting plate 204 and the fixing rod 206, in order to proceed to the next stage of stacking.
