Description

Technical Field

[0001] The present invention relates to the technical field of isostatic presses, and particularly to a dry-bag isostatic press. Background Art

[0002] Isostatic pressing treatment is to place the object to be processed in a sealed container filled with liquid, and gradually apply pressure through a pressurizing system to apply equal pressure to each surface of the object, so as to reduce the intermolecular distance and increase the density without changing the appearance shape, thereby improving the properties of the material.

[0003] For example, a rotary switching type double-station double-cylinder dry-bag isostatic press with the publication number of CN112959713A can reduce labor costs, improve work efficiency, and has simple operation and reduced labor intensity. However, in actual use, when processing products by adopting a double-station method, when adding powder materials into the mold, and then applying pressure to the mold to make the product form, when filling the powder materials into the mold, due to the double-station setting, it is not convenient to vibrate and compact the powder materials. Subsequently, during the isostatic pressing process, the gap between the powder materials is too large, which will affect the production quality of the product. Another example is a bottom vibration compaction mechanism for woven bag packaging materials with the publication number of CN219077541U. By using a crankshaft drive structure, it drives the flap to rotate back and forth to beat and compact, realizing an efficient packaging vibration compaction effect for woven bag packaging materials. And the device structure has strong applicability. Through four columns, it can be easily matched with a variety of equipment to improve the applicability of the device; the vibration compaction structure uses compressed air as power, with clean and environmentally friendly energy, reducing pollution problems caused during the production process of woven bag packaging materials; this mechanism has a simple structure, is convenient for installation, maintenance and use, the connection strength between each part is high, and the service life is long. However, in actual use, the vibration compaction function is realized through the reciprocating rotation of the flap. When using a multi-station dry-bag isostatic press, due to the multi-station setting, if you want to vibrate and compact the materials in the mold, you need to stop the equipment or place the mold on the vibration compaction equipment for separate vibration compaction. Since the multi-station setting is mainly to save working time and improve work efficiency, if the mold is directly removed or the equipment is stopped, it will affect the continuity of the static pressure processing of the materials, reduce the work efficiency of multi-station processing, and make the multi-station setting unable to significantly improve work efficiency, there are certain defects in use.

[0004] Therefore, we propose a dry-bag isostatic press to solve the problems raised above. Summary of the Invention

[0021] Preferably, a telescopic tube is connected through the center of the top of the end cover, and the top end of the telescopic tube passes through the cross plate and is connected with a feed hose.

[0022] By adopting the above technical solution, it is convenient to fill the powder in the die.

[0023] Compared with the prior art, the beneficial effect of the present invention is that for this dry-bag isostatic press, two sets of compaction assemblies are symmetrically arranged on the top of the turntable. After the powder is filled into the die, the powder can be compacted as the turntable rotates, avoiding affecting the subsequent production quality. At the same time, while ensuring multi-station continuous operation, downtime can be avoided, ensuring the continuity of work, avoiding the reduction of the work efficiency of the multi-station mode due to compaction, and improving the practicability; 1. When static pressure is applied to the powder material, the mold is filled with the material. After the powder material is filled into the mold, the upper cover is removed. Then, the driving motor is started to drive the driving gear to rotate, so that the turntable can be driven to rotate a quarter of a circle by meshing with the internal gear ring, and the just-filled mold is rotated to one side of the static pressure mechanism. During the rotation of the mold, the rotating rod can be rotated. After the rotating rod rotates, the two connecting plates can be pushed away from each other by two sets of bumps, so that the movable rod moves and stretches the telescopic spring. After the bumps leave the connecting plates, the movable rod is reset under the action of the telescopic spring, so that the rotation of the rotating rod can drive the movable rod to reciprocate. After the movable rod reciprocates, the sliding rod can be pushed to reciprocate through the support frame, so that the rotating sleeve rotates reciprocally on the support block, and the sliding rod can slide on the rotating sleeve. Furthermore, the compaction head can continuously swing. Through the swinging of the compaction head, the outside of the mold can be knocked and compacted. Therefore, during the process of rotating the mold to one side of the static pressure mechanism after it is filled, the mold is continuously compacted, making the powder material more compact, avoiding affecting the subsequent static pressure effect. Then, the upper cover is covered on the top of the mold. Then, the tray arranged on the static pressure mechanism can eject the turntable from the top of the mold base, and then the tray rises and enters the static pressure mechanism. Then, the mold can be extruded. Four workstations are arranged on the turntable for filling, static pressure, removal, and placement respectively, which can ensure the continuity of the static pressure. Through the compaction component, after the powder material is filled into the mold, it can be compacted as the turntable rotates, avoiding affecting the subsequent production quality. At the same time, while ensuring the continuous operation of multiple workstations, downtime can be avoided, the continuity of the work can be ensured, and the work efficiency of the multi-station mode can be prevented from being reduced due to compaction, improving the practicability; 2. During the process of controlling the turntable to rotate to the side of the static pressure mechanism, the rotation of the turntable causes the rotating shaft to perform circular rotation. During the circular rotation of the rotating shaft, the rotating gear can rotate by meshing with the first teeth on the outer side of the first mounting ring, enabling the connecting shaft to rotate through the cooperation of the positioning strip and the positioning groove. Then, the rotating rod is driven to rotate through the meshing of the first bevel gear and the second bevel gear. During the rotation of the connecting shaft, the threaded rod (the thread direction of the threaded rod in the attached drawing is only for illustration) can be driven to rotate through the cooperation of the first belt pulley and the second belt pulley. After the threaded rod rotates, the U-shaped frame can be driven to move downward through the threaded connection with the L-shaped frame, causing the telescopic plate to retract. The downward movement of the U-shaped frame can change the vibration compacting position, thereby enabling uniform vibration compaction of the mold. After the static pressure of the mold is completed, it is re-placed on the turntable, and then the turntable continues to rotate. At this time, the rotating gear can mesh with the second teeth on the second mounting ring, causing the rotating shaft to rotate in the reverse direction. At the same time, the vibration compaction head can strike the mold to assist in demolding the products in the mold. Moreover, after the rotating gear meshes with the second teeth, the rotation direction changes, causing the threaded rod to rotate in the reverse direction, which can drive the U-shaped frame to move upward to assist in resetting the U-shaped frame, facilitating subsequent processing. Therefore, the mold can be vibration compacted and assisted in demolding through the rotation of the turntable, ensuring the continuity of processing while avoiding affecting the processing quality and improving the practicality; 3. The turntable controls the mold to rotate under the end cover. Then, the end cover can be driven to move downward by the electric push rod, so that the end cover covers the top of the mold. The powder is fed into the feeding hose through the pump body, and then the material enters the mold through the telescopic tube. When the powder is filled into the mold, it can be blocked by the end cover to prevent the powder from dispersing during the filling process and avoid polluting the working environment, thus improving the practicality.

Moreover, a vertical rod 107 is rotatably connected to the center of the turntable 103, and the vertical rod 107 is fixedly connected to the column 102; A compaction assembly 2, symmetrically arranged on the top of the turntable 103, and the compaction assembly 2 includes a telescopic plate 201; The telescopic plates 201 are symmetrically installed at the top of the turntable 103 and on both sides of the working station. At the top of the two telescopic plates 201, a U-shaped frame 202 is fixedly installed. A rotating rod 203 is rotatably connected inside the U-shaped frame 202. Mounting frames 204 are symmetrically installed inside the U-shaped frame 202. Inside the two mounting frames 204, movable rods 205 are slidably connected. On the side where the two movable rods 205 are close to each other, connecting plates 207 are fixedly installed on both sides; The movable plate 208 is fixedly installed on the side where the two movable rods 205 are away from each other. On the outer part of the rotating rod 203, two groups of convex blocks 206 are symmetrically installed between the two connecting plates 207. The convex blocks 206 are slidably connected with the connecting plates 207. On the outer parts of the two movable rods 205, between the movable plate 208 and the mounting frames 204, telescopic springs 209 are sleeved. The two ends of the telescopic springs 209 are respectively fixedly connected with the mounting frames 204 and the movable plate 208; On one side of the two mounting frames 204 of the U-shaped frame 202, support blocks 210 are symmetrically installed. Between the two support blocks 210 on each side, a rotating sleeve 211 is rotatably connected. Inside the rotating sleeve 211, a sliding rod 212 is slidably connected. At one end of the sliding rod 212, a vibrating head 214 is fixedly installed. On one side of the movable plate 208, support frames 213 are symmetrically installed. The sliding rod 212 is hinged with the two support frames 213; At the bottom of the turntable 103, an internal gear ring 108 is fixedly installed. Above one side of the column 102, a driving motor 109 is fixedly installed. At the output end of the driving motor 109, a driving gear 110 is fixedly installed. The driving gear 110 is meshed with the internal gear ring 108. At the bottom of the turntable 103, an annular groove 111 is opened outside the internal gear ring 108. Outside the driving motor 109 on the outer part of the column 102, two groups of support rods 112 are symmetrically installed. The two support rods 112 are both slidably connected with the annular groove 111.

[0028] Example 1: As Figures 1-6As shown in the figure, when static pressure is applied to the powder material, the mold 104 is filled with the powder material. After the powder material is filled into the mold 104, the upper cover 105 is removed. Then, the driving motor 109 is started to drive the driving gear 110 to rotate, so that the turntable 103 can be driven to rotate a quarter of a turn by engaging with the internal gear ring 108, and the just-filled mold 104 is rotated to one side of the static pressure mechanism 101. During the rotation of the mold 104, the rotating rod 203 can be rotated. After the rotating rod 203 rotates, two connecting plates 207 can be pushed away from each other by two sets of bumps 206, so that the movable rod 205 moves and stretches the telescopic spring 209. After the bumps 206 leave the connecting plates 207, the movable rod 205 is reset under the action of the telescopic spring 209, so that the rotation of the rotating rod 203 can drive the movable rod 205 to reciprocate. After the movable rod 205 reciprocates, the sliding rod 212 can be pushed to reciprocate through the support frame 213, so that the rotating sleeve 211 rotates reciprocally on the support block 210, and the sliding rod 212 can slide on the rotating sleeve 211. Furthermore, the compaction head 214 can continuously swing. Through the swinging of the compaction head 214, the outside of the mold 104 can be knocked and compacted. Therefore, during the process that the mold 104 filled with the powder material rotates to one side of the static pressure mechanism 101, the mold 104 is continuously compacted, making the powder material more compact, avoiding affecting the subsequent static pressure effect. Then, the upper cover 105 is covered on the top of the mold 104. Then, the tray arranged on the static pressure mechanism 101 can push out the turntable 103 from the top of the mold base 106, and then the tray rises and enters the static pressure mechanism 101. Then, the mold 104 can be extruded. Four working stations are arranged on the turntable 103, namely filling, static pressure, removal, and placement, which can ensure the continuity of the static pressure. After the powder material is filled into the mold 104 by the compaction assembly 2, the powder material can be compacted as the turntable 103 rotates, avoiding affecting the subsequent production quality. At the same time, while ensuring the continuous operation of multiple working stations, it can avoid shutdown, ensuring the continuity of the work, avoiding reducing the work efficiency of the multi-station mode due to compaction, and improving the practicability.

[0029] One end of the rotating rod 203 passes through the U-shaped frame 202 and is fixedly installed with a first bevel gear 215. And a positioning frame 216 is fixedly installed below the first bevel gear 215 on the outside of the U-shaped frame 202. And a connecting shaft 217 is rotatably connected inside the positioning frame 216. At the same time, a second bevel gear 218 is fixedly installed at the top of the connecting shaft 217. Moreover, the second bevel gear 218 is meshed and connected with the first bevel gear 215; A connection groove 221 is formed inside the connecting shaft 217, and a rotating shaft 220 is slidably connected inside the connection groove 221. Positioning bars 222 are symmetrically installed inside the connection groove 221. At the same time, positioning grooves 223 are symmetrically formed above the outer part of the rotating shaft 220. Moreover, the positioning bars 222 are slidably connected with the positioning grooves 223. A limiting frame 219 is fixedly installed below the outer part of the rotating shaft 220, and the limiting frame 219 is fixedly connected with the turntable 103; A rotating gear 224 is fixedly installed at the bottom end of the rotating shaft 220. Two groups of mounting rods 225 are symmetrically installed below the outer part of the vertical rod 107. The tops of each group of two mounting rods 225 are respectively fixedly installed with a first mounting ring 226 and a second mounting ring 228. At the same time, a number of first teeth 227 are fixedly installed on the outer side of the first mounting ring 226. Moreover, a number of second teeth 229 are fixedly installed on the inner side of the second mounting ring 228. The number of the first teeth 227 is equal to that of the second teeth 229. The rotating gear 224 is meshed with the first teeth 227 and the second teeth 229; One side of the top of the limiting frame 219 is fixedly installed with an L-shaped frame 230. A threaded rod 231 is threadedly connected to one side inside the L-shaped frame 230. The top of the threaded rod 231 is rotatably connected with the U-shaped frame 202. At the same time, a first pulley 232 is fixedly installed above the outer part of the connecting shaft 217. A second pulley 233 is fixedly installed above the outer part of the threaded rod 231. Moreover, the second pulley 233 is rotationally connected with the first pulley 232 through a belt.

[0030] Embodiment Two: As Figures 1-5 and Figures 7-8As shown, during the process of rotating the control turntable 103 to the side of the static pressure mechanism 101, the rotation of the turntable 103 causes the rotating shaft 220 to perform a circular rotation. During the circular rotation of the rotating shaft 220, the rotating gear 224 can rotate by meshing with the first teeth 227 on the outer side of the first mounting ring 226, so that the connecting shaft 217 can be driven to rotate through the cooperation of the positioning strip 222 and the positioning groove 223. Then, the rotating rod 203 is driven to rotate through the meshing of the first bevel gear 215 and the second bevel gear 218. During the rotation of the connecting shaft 217, the threaded rod 231 can be driven to rotate through the cooperation of the first belt pulley 232 and the second belt pulley 233. After the threaded rod 231 rotates, the U-shaped frame 202 can be driven to move downward through the threaded connection with the L-shaped frame 230, so that the telescopic plate 201 retracts. The downward movement of the U-shaped frame 202 can change the vibration compacting position, and then the mold 104 can be evenly vibration compacted. After the static pressure of the mold 104 is completed, it is placed on the turntable 103 again. Then, the turntable 103 continues to rotate. At this time, the rotating gear 224 can mesh with the second teeth 229 on the second mounting ring 228, so that the rotating shaft 220 rotates in the reverse direction. At the same time, the vibration compacting head 214 can strike the mold 104 to assist in demolding the product in the mold 104. Moreover, after the rotating gear 224 meshes with the second teeth 229, the rotation direction changes, so that the threaded rod 231 rotates in the reverse direction, which can drive the U-shaped frame 202 to move upward to assist the U-shaped frame 202 to reset, facilitating subsequent processing. Furthermore, the mold 104 can be vibration compacted and assisted in demolding through the rotation of the turntable 103, ensuring the continuity of processing while avoiding affecting the processing quality and improving the practicability.

[0031] The filling component 3 is arranged above one side of the vertical rod 107; The filling component 3 includes a cross plate 301 fixedly installed above the vertical rod 107. One side of the top of the cross plate 301 is fixedly installed with an electric push rod 302, and the movable end of the electric push rod 302 is fixedly installed with an end cover 303. At the same time, one side of the top of the end cover 303 is fixedly installed with a guide rod 304, and the guide rod 304 is slidably connected with the cross plate 301; A telescopic tube 305 is connected through the center of the top of the end cover 303, and the top end of the telescopic tube 305 passes through the cross plate 301 and is connected with a feeding hose 306.

[0032] Embodiment 3: As Figures 1-3 and Figure 9As shown in the figure, the turntable 103 controls the mold 104 to rotate under the end cap 303. Then, the electric push rod 302 can drive the end cap 303 to move downward, so that the end cap 303 covers the top of the mold 104. The powder material is fed into the feeding hose 306 through the pump body. Then, the material enters the mold 104 through the telescopic tube 305. When the powder material is filled into the mold 104, it can be blocked by the end cap 303, avoiding the dispersion of the powder material during the filling process, preventing the pollution of the working environment, and improving the practicability.

[0033] Working principle: When using this dry bag isostatic press, first, according to Figures 1-9 As shown in the figure, when static pressing the powder material, the mold 104 is filled with the powder material. After the powder material is filled into the mold 104, the upper cover 105 is removed. Then, the driving motor 109 is started to drive the driving gear 110 to rotate, so that the turntable 103 can be driven to rotate a quarter of a circle by engaging with the internal gear ring 108, making the just-filled mold 104 rotate to one side of the static pressing mechanism 101. During the rotation of the mold 104, the rotating rod 203 can be rotated. After the rotating rod 203 rotates, the two connecting plates 207 can be pushed away from each other by the two sets of convex blocks 206, so that the movable rod 205 moves and stretches the telescopic spring 209. After the convex block 206 leaves the connecting plate 207, the movable rod 205 is reset under the action of the telescopic spring 209, so that the rotation of the rotating rod 203 can drive the movable rod 205 to reciprocate. After the movable rod 205 reciprocates, the sliding rod 212 can be pushed to reciprocate through the support frame 213, so that the rotating sleeve 211 rotates reciprocally on the support block 210, and the sliding rod 212 can slide on the rotating sleeve 211. Furthermore, the compaction head 214 can continuously swing. Through the swinging of the compaction head 214, the outside of the mold 104 can be knocked and compacted. Thus, during the process that the mold 104 after being filled rotates to one side of the static pressing mechanism 101, the mold 104 is continuously compacted, making the powder material more compact, avoiding affecting the subsequent static pressing effect. Then, the upper cover 105 is covered on the top of the mold 104. Then, the tray set on the static pressing mechanism 101 can push out the turntable 103 from the top of the mold base 106, and then the tray rises and enters the static pressing mechanism 101. Then, the mold 104 can be extruded. Four workstations are set on the turntable 103 for filling, static pressing, removing, and placing respectively, which can ensure the continuity of static pressing. During the process of controlling the turntable 103 to rotate to the side of the static pressure mechanism 101, the rotation of the turntable 103 causes the rotating shaft 220 to perform circular rotation. During the circular rotation of the rotating shaft 220, the rotating gear 224 can rotate by meshing with the first teeth 227 on the outer side of the first mounting ring 226, so that the connecting shaft 217 can be driven to rotate through the cooperation of the positioning strip 222 and the positioning groove 223. Then, the rotating rod 203 is driven to rotate through the meshing of the first bevel gear 215 and the second bevel gear 218. During the rotation of the connecting shaft 217, the threaded rod 231 can be driven to rotate through the cooperation of the first belt pulley 232 and the second belt pulley 233. After the threaded rod 231 rotates, it can drive the U-shaped frame 202 to move downward through the threaded connection with the L-shaped frame 230, so that the telescopic plate 201 retracts. The downward movement of the U-shaped frame 202 can change the vibration position, and then the mold 104 can be vibrated evenly. After the static pressure of the mold 104 is completed, it is placed on the turntable 103 again. Then, the turntable 103 continues to rotate. At this time, the rotating gear 224 can mesh with the second teeth 229 on the second mounting ring 228, so that the rotating shaft 220 rotates in the reverse direction. At the same time, the vibrating head 214 can strike the mold 104, which can assist the product in the mold 104 to be demolded. And after the rotating gear 224 meshes with the second teeth 229, the rotation direction changes, so that the threaded rod 231 rotates in the reverse direction, which can drive the U-shaped frame 202 to move upward to assist the U-shaped frame 202 to reset, which is convenient for subsequent processing. Furthermore, the mold 104 can be vibrated and assisted in demolding through the rotation of the turntable 103, which ensures the continuity of processing and avoids affecting the processing quality. The turntable 103 controls the mold 104 to rotate under the end cover 303. Then, the end cover 303 can be driven to move downward by the electric push rod 302, so that the end cover 303 covers the top of the mold 104. The powder is introduced into the feeding hose 306 through the pump body. Then, the material enters the mold 104 through the telescopic tube 305. When the powder is filled into the mold 104, it can be blocked by the end cover 303 to avoid the dispersion of the powder during the filling process.
