Description

Technical Field

[0001] The invention relates to the technical field of graphite production, in particular to a pressing device for processing high-temperature gas-cooled reactor nuclear graphite materials. Background Art

[0002] High-temperature gas-cooled reactor nuclear graphite material has become a key material in high-temperature gas-cooled reactors due to its excellent neutron moderation performance, high purity, low impurity content, high heat resistance, good thermal conductivity and radiation resistance. It is often processed into spherical, cylindrical, irregular shapes, etc., and used in important components such as fuel element matrix, moderator, and reflector layer.

[0003] The prior art discloses a graphite product pressing and forming device with publication number CN118721842A, which drives the pressing frame to slide up and down through the output end of the hydraulic cylinder, and the connecting rod synchronously drives the sliding frame to slide on the inner wall of the device base. After the pressing block cooperates with the mold to press and form the graphite product, the push rod pushes out the pressed and formed graphite product on the sliding plate, which is convenient for rapid material extraction of graphite products and improves the production efficiency of graphite products. The limit block and the limit groove are used in combination to improve the sliding stability of the push rod and the situation where the sliding plate tilts and causes the graphite product to fall. The scraper scrapes the inner wall of the mold as it slides on the sliding plate, reduces the adhesion of residual material on the inner wall of the mold, and scrapes the residual material into the collection tank for collection, thereby improving the quality of the graphite product pressing and forming.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] In actual use, it was found that after the high-temperature gas-cooled reactor nuclear graphite material pressing device completed the pressing and molding and pushed out the workpiece, it could not automatically place the workpiece neatly in the material box, and required manual secondary placement. This manual placement method not only increased labor costs, but also reduced production efficiency. In batch production, the speed of manual placement was much lower than the speed of machine production, resulting in serious restrictions on the efficiency of the entire production process, which could not meet the requirements of modern industrial production for efficiency, precision, and automation. In order to solve the above problems, the following structure was specially invented.

[0030] like Figures 1-8The pressing device for processing high-temperature gas-cooled reactor core graphite materials shown in the figure includes a pressing machine base 1, on which is provided a pressing assembly 2 for pressing graphite materials. The pressing assembly 2 mainly presses graphite products of the shape and performance required for the high-temperature gas-cooled reactor core by mixing graphite powder with a binder, pre-pressing and forming, heating and curing, and then calcining and graphitizing. The side wall of the pressing machine base 1 is fixedly connected to an L-shaped plate 3, on which a collection box 4 is provided, the top of the pressing machine base 1 is fixedly connected to a fixed plate 5, the side wall of the fixed plate 5 is fixedly connected to a main push electric telescopic cylinder 6, and the pressing machine base 1 is provided with an upper U-shaped plate 7. A pair of straight blocks 8 are provided on the upper U-shaped plate 7. The side walls of the straight blocks 8 are fixedly connected to the oblique blocks 9. The tops of the straight blocks 8 and the oblique blocks 9 are penetrated by extrusion grooves 10. A main push frame 11 is provided on the inner side of the upper U-shaped plate 7. Side push plates 12 are provided at both ends of the inner side of the upper U-shaped plate 7. Extrusion rods 13 are provided on the side push plates 12. The extrusion rods 13 are inserted into the inner side of the extrusion groove 10. T-slots are provided on the sides of the straight blocks 8 that are close to each other. The two ends of the inner side of the main push frame 11 are slidably connected to the telescopic plates 25. The tops of the telescopic plates 25 that are away from each other are fixedly connected to the T-blocks 14. The T-blocks 14 are slidably connected to the inner sides of the T-slots.

[0031] The side wall of the L-shaped plate 3 is fixedly connected to a displacement electric telescopic cylinder 17, the output end of the displacement electric telescopic cylinder 17 passes through the side wall of the L-shaped plate 3 and is fixedly connected to an insertion frame 18, and the side wall of the collection box 4 is fixedly connected to an insertion block 19 for inserting into the insertion frame 18;

[0032] A pair of lower U-shaped plates 15 are fixedly connected to the side walls of the upper U-shaped plate 7, and a secondary electric telescopic cylinder 16 is fixedly connected to the side walls of the lower U-shaped plate 15. The output end of the main electric telescopic cylinder 6 passes through the side wall of the fixed plate 5 and is fixedly connected to the side wall of the upper U-shaped plate 7. The output end of the secondary electric telescopic cylinder 16 passes through the inner side of the lower U-shaped plate 15 and is fixedly connected to the adjustment frame 21. The straight blocks 8 are all slidably connected to the inner side of the adjustment frame 21.

[0033] Side plates 22 are slidably connected to both sides of the outer wall of the upper U-shaped plate 7 relative to the position next to the main push frame 11. The setting of the side plates 22 can push the unmerged graphite to move, ensuring that the graphite is stably pushed to the side of the collection box 4. A stop block 24 is fixedly connected to the inner side of the upper U-shaped plate 7. The setting of the stop block 24 can limit the sliding position of the main push frame 11.

[0034] In the process of pressing the high-temperature gas-cooled reactor nuclear graphite, the pressed graphite material is first placed in the pressing tank, and then the pressing assembly 2 is started to press the graphite material. After the pressing is completed, the formed graphite is ejected by the jacking assembly on the pressing machine base 1, and then the main push electric telescopic cylinder 6 can be controlled to start and drive the upper U-shaped plate 7 to move, and then the inner side of the upper U-shaped plate 7 moves to the side of the ejected cylindrical graphite and is located next to the main push frame 11. Then, under the continued drive of the main push electric telescopic cylinder 6, the main push frame 11 and the side plate 22 will simultaneously push the graphite to move, and move the graphite to the side of the collection box 4. Then, the secondary push electric telescopic cylinder 16 can be controlled to start and drive the adjustment frame 21, the straight block 8 and the oblique block 9 to move;

[0035] At this time, the extrusion rod 13 on the side push plate 12 is inserted into the oblique groove in the extrusion groove 10, and then with the lateral movement of the straight block 8 and the oblique block 9, the inclined end of the extrusion groove 10 will push the extrusion rod 13 to move, and at the same time drive the two side push plates 12 to move toward the middle, thereby pushing the graphite in the upper U-shaped plate 7 to move toward the middle, until the graphite on both sides and the graphite in the middle are merged together (it should be noted here that, since the graphite is first pushed to the side of the collection box 4 by the main push frame 11, the graphite is close to the main push frame 11 and the side plate 22 during the pushing process of the side push plate 12, and then during the pushing process of the side push plate 12, The graphite will move toward the middle along the main push frame 11 without tilting), and at the same time, the extrusion rod 13 slides from the oblique groove of the extrusion groove 10 to the straight section, thereby releasing the extrusion of the extrusion rod 13, and in this process, the T-block 14 on the telescopic plate 25 will slide in the T-slot, so that when the graphite is squeezed together, the T-block 14 will move to the end of the T-slot, and then move with the straight block 8, thereby pushing the main push frame 11 and the telescopic plate 25 to move, pushing the merged graphite to move into the collection box 4, thereby realizing automatic sorting of the graphite, and then repeating the reverse operation to reset;

[0036] Finally, after the main push electric telescopic cylinder 6 has run multiple times and pushed multiple groups of graphite into the collection box 4, the displacement electric telescopic cylinder 17 can be controlled to start and drive the insertion frame 18 to move. Since the insertion block 19 is inserted in the insertion frame 18, it will pull the collection box 4 to move at the same time, thereby changing the collection position of the collection box 4, which is convenient for the subsequent automatic collection of graphite. Finally, when the graphite in the collection box 4 is full, lift the collection box 4 and pull the insertion block 19 out of the insertion frame 18, then insert the insertion block 19 on the new collection box 4 into the insertion frame 18, and control the displacement electric telescopic cylinder 17 to reset.

[0037] In order to improve the stability of the device during operation, the side walls of the side push plate 12 are fixedly connected with a guide rod 20, and the guide rod 20 is set through the outer wall of the upper U-shaped plate 7. Through the setting of the guide rod 20, the guide rod 20 can be driven to move together during the movement of the side push plate 12, thereby guiding the sliding of the side push plate 12, thereby improving the stability of the device during operation. At the same time, the guide rod 20 is located on the inner side of the upper column of the pressing assembly 2 and will not be hindered by the column.

[0038] When the straight block 8 is reset, the T-shaped block 14 can be pulled back together with the main push frame 11 by the magnet 27. After the T-shaped slot is gradually moved to the side of the T-shaped block 14, the T-shaped block 14 will be pulled to the inside of the T-shaped slot by the suction force of the magnet 27. Then, under the continued movement of the straight block 8, the T-shaped block 14, the telescopic plate 25 and the main push frame 11 can be pushed to move together, thereby pushing the merged graphite to move. It should be noted here that when the magnet 27 is able to be adsorbed on the T-shaped block 14, the extrusion rod 13 has moved from the inclined part of the extrusion groove 10 to the straight section, and the side push plate 12 has completed the merging of the graphite. Therefore, in the subsequent reset process, when the straight block 8 is reset, the T-shaped block 14 can be pulled back together, and after the main push frame 11 is reset, it will be restricted by the stop block 24 and cannot be reset with the straight block 8, thereby pulling the T-shaped block 14 out of the magnet 27.

[0039] To sum up, through the design of the above structure, the three cylindrical graphite workpieces that have been pressed can be automatically pushed out and the three graphite pieces can be pushed together. Then, the main push frame 11 is driven to push the three graphite pieces into the collection box 4 for collection and processing, thereby realizing automatic sorting and unloading of the pressed graphite. There is no need for workers to place the formed graphite workpieces one by one into the collection box 4, which greatly improves the convenience of the device.

[0040] Based on the above embodiments, it was found during use that if the above structure is a fixed structure, it can only sort and cut cylindrical graphite of the same size, which cannot meet user needs. In order to solve the above problem, the above structure was further improved.

[0041] A pair of limit frames 23 are slidably connected to the top of the upper U-shaped plate 7, and the straight block 8 is slidably connected to the inner side of the limit frame 23. A connecting block 26 is fixedly connected between the limit frame 23 and the top of the side plate 22. The setting of the limit frame 23 and the connecting block 26 can limit the position of the side plate 22, ensuring that when the spacing between the straight blocks 8 is adjusted, the side plate 22 can be driven to move by the limit frame 23 and the connecting block 26, and the position of the side plate 22 is adjusted to avoid hindering the normal movement of the telescopic plate 25. A scale groove 31 is opened at the top of one of the side plates 22. The setting of the scale groove 31 makes it easy to accurately know the adjusted spacing of the straight blocks 8, and accurately adjust according to the diameter of the graphite, thereby improving the convenience of the device.

[0042] A bidirectional screw rod 29 is rotatably connected to the inner side of the adjustment frame 21. The side wall of the bidirectional screw rod 29 passes through the outer wall of the adjustment frame 21 and is fixedly connected to a rotating block 30. The setting of the rotating block 30 facilitates the rotation of the bidirectional screw rod 29 to adjust the spacing between the straight blocks 8. The bidirectional screw rod 29 is threadedly connected to the inner wall of the straight block 8.

[0043] Three lower springs 32 are fixedly connected between the telescopic plates 25. A slide groove is provided at the top of the side push plate 12, and a plurality of positioning grooves 33 are equidistantly provided at the bottom of the slide groove. The bottom end of the extrusion rod 13 is slidably connected to the inner side of the slide groove. A circular hole is provided at the top of the extrusion rod 13, and a positioning rod 34 is slidably connected in the circular hole. The bottom end of the positioning rod 34 is inserted into the inner side of one of the positioning grooves 33. A positioning spring 28 is fixedly connected between the top of the extrusion rod 13 and the outer wall of the positioning rod 34.

[0044] When changing the size of the pressed graphite, first replace the mold on the pressing machine base 1 and the pressing parts on the pressing assembly 2, then pull the positioning rod 34 upward to pull the bottom end of the positioning rod 34 out of the positioning groove 33, and at the same time stretch the positioning spring 28 to release the sliding restriction of the extrusion rod 13, and then rotate the rotating block 30 to drive the bidirectional screw rod 29 to rotate, thereby driving the threaded straight block 8 to move to both sides, and at the same time driving the oblique block 9 to move, and because the T-block 14 is inserted in the T-slot, it will pull the T-block 14 and the telescopic plate 25 to move, and gradually compress the lower spring 32 , and in this process, the movement of the straight block 8 will drive the limit frame 23 to move, and then the side plate 22 will be driven to move at the same time through the connecting block 26, changing the position of the side plate 22, and at the same time, the movement of the oblique block 9 will push the extrusion rod 13 to slide in the slide groove through the extrusion groove 10, changing the position of the extrusion rod 13 on the side push plate 12. After the adjustment is completed, the positioning rod 34 is released, and the bottom end of the positioning rod 34 is inserted into the corresponding positioning groove 33 under the elastic force of the positioning spring 28 to limit the position of the extrusion rod 13, thereby completing the adjustment of the extrusion spacing of the side push plate 12.

[0045] In summary, through the design of the above structure, the distance that the three pieces of extruded graphite move toward the middle can be adjusted according to the diameter of the pressed cylindrical graphite, and the length of the main push frame 11 can be changed at the same time, so that cylindrical graphite of different diameters can be pushed into the collection box 4, thereby sorting and collecting graphite of various plans, greatly improving the universal performance of the device.

[0046] The basic principles, main features and advantages of the present invention are shown and described above.

[0047] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
