Description

Technical Field

[0001] This invention relates to the technical field of magnetic core fabrication. More specifically, this invention relates to a pressing and molding apparatus for magnetic cores used in power grids. Background Technology

[0002] Magnetic cores are key components in electrical equipment, widely used to enhance magnetic fields and improve inductance. Their manufacturing process typically involves: thoroughly mixing various powdered raw materials, pressing them into a mold to form a cylindrical semi-finished magnetic core, transferring the semi-finished product to the material holes of a receiving tray, and then feeding the entire core into a sintering furnace for high-temperature sintering to harden and solidify it.

[0003] However, in the current process, after the semi-finished magnetic cores are demolded from the mold, they must be manually picked up one by one and inserted into the various holes of the receiving plate. This operation is cumbersome, time-consuming, and has a low degree of automation, resulting in low production efficiency. At the same time, the newly pressed semi-finished magnetic cores have low structural strength and are brittle. When manually inserted into the holes of the receiving plate, their edges and corners are very easy to bump against the holes, causing chipping or damage, which seriously affects the product yield and final performance.

[0009] More preferably, it also includes spring three; the pressure block one located in the upper middle part is fixedly connected to the top plate, and the other pressure blocks one located in the upper part are all slidably connected to the top plate; the pressure block one located in the lower middle part is fixedly connected to the connecting block one, and the other pressure blocks one located in the lower middle part are all slidably connected to the connecting block one; several spring three are fixedly connected between each pair of corresponding pressure blocks one.

[0010] More preferably, it also includes a protective component, which includes a spring four and a round rod three; several spring fours are fixedly connected to each pressure block one; a round rod three is fixedly connected to each spring four, and the round rod three is in a damped sliding connection with the corresponding pressure block one.

[0015] Compared with the prior art, the present invention has the following advantages: First, by cooperating with movable plate one, movable plate two, pressure block one and round rod one, after extrusion molding, the entire row of semi-finished magnetic cores can be simultaneously inserted into the material hole of the bearing block by manually moving movable plate one.

At the same time, spring three, which is used to bring the pressure blocks one closer together under normal conditions, can be used to shake off the clumps of impurities remaining on the pressure blocks one, so as to avoid interfering with the subsequent pressing and molding operation.

[0018] Fourth, the combination of spring four and round rod three-phase protection provides buffer protection for pressure block one, preventing it from loosening and deforming due to long-term impact, thereby avoiding interference with the extrusion molding operation. Attached Figure Description

[0032] The extrusion assembly includes a telescopic cylinder 201, a pressure block 202, and a positioning block 203; two telescopic cylinders 201 are bolted to the top of the inner side of the housing 1; the telescopic ends of all telescopic cylinders 201 are welded with the pressure block 202; four positioning blocks 203 are welded on the connecting plate 2, and the positioning blocks 203 are made of wear-resistant material; four through slots 92 are opened on the connecting block 4, and the through slots 92 cooperate with the positioning blocks 203 to position the connecting block 4; each positioning block 203 contacts the corresponding movable plate 7, and the movable plate 7 is limited by the positioning block 203.

[0033] It also includes auxiliary components, including connecting block 204, connecting block 305, movable block 206, spring 1 207, linkage block 208, spring 209, and round rod 2010; two connecting blocks 204 are bolted to the connecting plate 2, and the connecting blocks 204 are made of alloy material; one connecting block 3 205 is bolted to each connecting block 204; two movable blocks 206 are slidably connected to each connecting block 3 205; and two springs are fixed to each movable block 206. Spring 207 is fixedly connected to the corresponding connecting block 205; a linkage block 208 is slidably connected to each connecting block 205; the contact surfaces of the movable block 206 and the linkage block 208 are both set as inclined surfaces; both the movable block 206 and the linkage block 208 are made of wear-resistant material; a spring 209 is fixedly connected between each connecting block 205 and the corresponding linkage block 208; a round rod 2010 is welded to each movable plate 7; two through slots 293 are opened on the connecting block 4.

[0034] It also includes a moving component, which includes an electric slide rail 2011, an electric slider 2012, and a receiving plate 2013; two electric slide rails 2011 are bolted to the connecting plate 2; an electric slider 2012 is slidably connected to each electric slide rail 2011; all electric sliders 2012 are fixedly connected to the receiving plate 2013, and the receiving plate 2013 is moved horizontally by the electric sliders 2012.

[0035] First, the top plate 6 is manually moved upwards, causing the movable plate 8, pressure block 9, and round rod 10 on it to move upwards, exposing the cavity 91. Then, the powder mixture is manually poured into the cavity 91. Next, the top plate 6 is reinserted onto the upper side of the connecting block 4, and the movable plate 8 is reinserted onto the upper side of the movable plate 7. Then, the telescopic cylinder 201 moves the pressure block 202 downwards, causing it to contact the upper center of the top plate 6. The pressure block 202 then pushes the top plate 6 downwards. Plate 6 drives the upper pressure block 9 downwards, thereby extruding the mixed powder in cavity 91 to produce a cylindrical magnetic core semi-finished product. Then, the connecting block 4 and its parts are manually moved upwards away from the connecting plate 2, and the side plate 5 is removed to expose the end of the magnetic core semi-finished product. Then, the connecting block 4 and its parts are rotated 90 degrees so that the exposed end of the magnetic core semi-finished product faces downwards. Finally, the connecting block 4 and the side plate 5 are inserted into the movable block 206. At this time, the positions of the connecting block 4 and its parts are as follows: Figure 7As shown, the electric slide rail 2011 and electric slider 2012 are activated. The electric slider 2012 drives the receiving plate 2013 to move to the right, and the receiving plate 2013 drives the firing block 11 to move to the right, so that the first row of material holes on the far right of the firing block 11 moves to below the semi-finished magnetic core. Then, the two movable plates 7 are manually moved in opposite directions. The movable plates 7 drive the pressing blocks 9 located at the lower ends to move. At the same time, the movable plates 7 drive the movable plates 8 to move, and the movable plates 8 drive the pressing blocks 9 located at the upper ends to move. That is, the pressing blocks 9 located at the upper and lower ends move in opposite directions at the same time. During this process, the pressing blocks 9 and the round First, rod 10 slides relative to each other. When the relative movement reaches its limit, pressure block 9 pulls rod 10 to move, and rod 10 pulls the corresponding pressure block 9 to move, thus causing the pressure blocks 9 in the same row to unfold relative to each other. The pressure blocks 9 in the upper and lower rows unfold synchronously, thus separating each magnetic core semi-finished product and aligning each magnetic core semi-finished product with the material hole of the firing block 11 below it. During this process, movable plate 7 also drives rod 2010 to move, causing rod 2010 to pass through through slot 293 and contact linkage block 208. Then, rod 2010 pushes linkage block 208 and compresses spring 209. Simultaneously, spring 209 forces the corresponding two movable blocks 206 to move in opposite directions and compresses spring 207. Movable blocks 206 drive connecting block 4 and side plate 5 to move in opposite directions, causing the two rows of pressing blocks 9 to move in opposite directions. This stops pressing blocks 9 from limiting the semi-finished magnetic cores. At this time, the entire row of semi-finished magnetic cores falls simultaneously into the material hole of the sintering block 11, completing rapid material placement. It should be understood that during the extrusion molding process, to avoid the formation of connected thin sheets between adjacent semi-finished magnetic cores, the semi-circular cavities on each pressing block 9 should be set close enough. During sintering, to ensure that each semi-finished magnetic core... The finished product can be heated fully and evenly. The material holes on the bearing block 11 should be spaced a certain distance apart so that the semi-finished magnetic cores inserted into the bearing block 11 can be spaced apart from each other. In use, the movable plate 7, movable plate 8, pressing block 9 and round rod 10 cooperate to allow the entire row of semi-finished magnetic cores to be inserted into the material holes of the bearing block 11 simultaneously by manually moving the movable plate 7 after extrusion molding. There is no need to remove the semi-finished magnetic cores from the pressing mold one by one and insert them into the material holes of the bearing block 11, which greatly improves production efficiency and eliminates the problem of edge and corner cracking caused by manual insertion of semi-finished magnetic cores, thus ensuring product quality.

[0036] After inserting the semi-finished magnetic core into the bearing block 11, the movable plate 7 is manually pushed back to its original position. The movable plate 7 then moves the movable plate 8 and the pressing block 9 back to their original positions. Next, the connecting block 4 and its components are removed from the movable block 206. The side plate 5 is then inserted back into the connecting block 4. The through slot 92 of the connecting block 4 is then fitted onto the outside of the four positioning blocks 203, allowing the connecting block 4 to rest on the connecting plate 2. At this point, the four through slots 92 and the four positioning blocks 203 work together to position the connecting block 4 and its components, aligning the center of the top plate 6 with the center of the pressing block 202. During the pressing process, the pressing block 202 applies pressure to the center of the top plate 6, ensuring that the top plate 6 applies uniform force to each pressing block 9, which improves the uniformity of the pressing process. Furthermore, the positioning blocks 203 pass through the through slots 92 and the four positioning blocks 203. After slot 92, it will contact the side of movable plate 7. At this time, the positioning block 203 blocks and limits movable plate 7, thereby blocking and limiting movable plate 8 and pressing block 9 in the horizontal direction. This prevents pressing block 9 from shifting horizontally due to pressure during the pressing process, thus avoiding interference with the molding of the magnetic core semi-finished product. In use, the through slot 92 and positioning block 203 cooperate to position connecting block 4 and its parts, so that pressing block 202 can apply pressure to the middle of top plate 6, thereby making the top plate 6 apply force evenly to each pressing block 9, which helps to improve the uniformity of pressing. At the same time, positioning block 203 is also used to block and limit pressing block 9 in the horizontal direction, preventing pressing block 9 from shifting horizontally due to pressure during the pressing process, thus avoiding interference with the molding of the magnetic core semi-finished product.

[0037] It also includes spring 3 2014; the upper middle pressure block 9 is fixedly connected to the top plate 6, and the other upper pressure blocks 9 are slidably connected to the top plate 6; the lower middle pressure block 9 is fixedly connected to the connecting block 4, and the other lower middle pressure blocks 9 are slidably connected to the connecting block 4; two springs 3 2014 are fixedly connected between each pair of corresponding pressure blocks 9, and the pressure blocks 9 are reset by the springs 3 2014.

[0038] During the process of filling the cavity 91 with powder mixture, manually removing the top plate 6 and its parts, and inserting the top plate 6 back into its original position, it is necessary to deliberately control all the pressure blocks 9 on the top plate 6 to be in a close fit and always in the center of the top plate 6. At the same time, after inserting the semi-finished magnetic core into the bearing block 11, before installing the connecting block 4 and its parts back into the pressing position, it is necessary to press the movable plate 7 to prevent the pressure blocks 9 from shifting or loosening. The operation is relatively difficult. Therefore, springs 3014 are set on the pressure blocks 9, and the pressure block 9 located in the upper center is fixed to the top plate 6, while the other pressure blocks 9 above are slidably connected to the top plate 6. The pressure block 9 located in the lower center is fixed to the connecting block 4, while the other pressure blocks 9 below are slidably connected to the top plate 6. Sliding connection with connecting block 14, under normal conditions, spring 32014 is in a stretched state. The elastic force of spring 32014 pulls each pressure block 9 together and positions the entire row of pressure blocks 9 in the middle of connecting block 14 (or top plate 6). No manual control is required. During expansion, the movable plate 17 and movable plate 28 pull the pressure block 9 to move. The pressure block 9 stretches spring 32014, allowing the pressure block 9 to separate smoothly. In use, under normal conditions, the elastic force of spring 32014 can pull each pressure block 9 together and position the entire row of pressure blocks 9 in the middle of connecting block 14 (or top plate 6). No manual control or adjustment is required, greatly reducing the difficulty of manual operation and improving convenience.

[0039] After inserting the semi-finished magnetic core into the bearing block 11, there will be clumps of impurities remaining on the pressing block 9. After manually removing the connecting block 4 and its parts from the movable block 206 and before inserting the side plate 5 back into its original position, manually move the two movable plates 7 in opposite directions to expand the pressing block 9 and stretch the spring 2014. Then stop moving the movable plates 7. At this time, the spring 2014 rebounds and causes the pressing block 9 to quickly move closer together and collide. Repeat this process of moving the movable plates 7 multiple times to shake off the clumps of impurities remaining on the pressing block 9, so as to avoid interfering with the subsequent pressing and molding operation. In use, the spring 2014, which is used to bring the pressing blocks 9 closer together under normal conditions, can be used to shake off the clumps of impurities remaining on the pressing block 9, so as to avoid interfering with the subsequent pressing and molding operation.

[0040] Example 2, based on Example 1, such as Figure 10 As shown, it also includes a protective component, which includes spring four 2015 and round rod three 2016; four spring four 2015 are fixedly connected to each pressure block one 9; a round rod three 2016 is fixedly connected to each spring four 2015, and the round rod three 2016 is damped and slidably connected to the corresponding pressure block one 9.

[0041] A camera is installed inside the casing 3, which can be used to monitor the production and processing operations.

[0042] A vacuum cleaner is installed inside the cover 3 to clean the dust inside the cover 3.

[0043] The cover 3 is provided with a dust-free operation window to prevent dust and impurities from the external environment from drifting into the inside of the cover 3.

[0044] Both the chassis 1 and the cover 3 are coated with an anti-corrosion layer to prevent rust and extend their lifespan.

[0045] During the process of shaking off residual powder, the pressure block 9 is prone to deformation and loosening due to prolonged impact, which can interfere with extrusion molding. Therefore, a protective component is installed on the pressure block 9. When the pressure block 9 unfolds in a back-to-back motion, the spring 4 2015, initially in a compressed state, rebounds and moves the round rod 3 2016, causing the end of the round rod 3 2016 to extend out of the pressure block 9. As the pressure block 9 continues its back-to-back motion, the spring 4 2015 rebounds to its limit, causing the pressure block 9 to move simultaneously with the spring 4 2015 and the round rod 3 2016, thus separating the two adjacent round rods 3 2016. During the powder removal process, the spring 3 2014 rebounds and moves the pressure block 9 towards each other, causing the pressure block 9 to move with the spring 4 2015 and the round rod 3 2016. The movement causes two adjacent round rods 32016 to collide and compress the spring 42015. At this time, the round rods 32016 can move inward into the pressure block 9 with damping. That is, in the final stage, the pressure block 9 slowly approaches, which can avoid the pressure block 9 from being deformed by impact. When the two round rods 32016 collide, the pressure block 9 can still be subjected to a large vibration effect under the action of the damping force between the round rods 32016 and the pressure block 9. Repeatedly moving the movable plate 7 in this way will shake off the powder impurities remaining on the pressure block 9. In use, the spring 42015 and the round rods 32016 work together to buffer and protect the pressure block 9, preventing the pressure block 9 from loosening and deforming due to long-term impact, thereby avoiding interference with the extrusion molding operation.
