The isostatic pressing process is to add raw materials to a mold, and the mold material is generally polyurethane or rubber with certain elasticity. In the isostatic pressing machine, the mold is subjected to uniform pressure of tens to hundreds of megapascals in all directions, so that the raw materials in the mold are compacted and formed.

[0060] The technical solutions in the embodiments of the present application will be clearly and completely explained below with reference to the drawings.

[0061] Embodiment one

[0062] As Figures 1-12 shown, a charging device for improving the performance of isostatic pressing products, comprising:

[0063] A transmission mechanism 1 drives the charging barrel 001 to move backward;

[0064] A discharging mechanism 2 is installed above the transmission mechanism 1 and is used to control the release of the powder;

[0065] A surrounding mechanism 3 is installed around the discharging mechanism 2 and comprises a blocking ring 31 arranged in close contact with the side wall of the charging barrel 001 and a moving assembly 32 fixedly connected above the blocking ring 31, the blocking ring 31 is used to isolate the powder from the side wall of the charging barrel 001 when the discharging mechanism 2 discharges; the moving assembly 32 comprises a rotating ring 321 fixedly connected above the blocking ring 31, a lifting unit 322 installed on the transmission mechanism 1 and used to control the lifting of the rotating ring 321, and a rotating unit 323 installed on the lifting unit 322 and used to control the rotation of the rotating ring 321;

[0066] A knocking mechanism 4 is symmetrically arranged on both sides of the transmission mechanism 1 and is used to knock the charging barrel 001 when discharging in cooperation with the lifting of the surrounding mechanism 3;

[0067] A pressing groove mechanism 5 is installed between the surrounding mechanism 3 and the discharging mechanism 2 and is used to press the discharged powder into a groove and discharge other powder.

[0068] In the embodiment, the knocking mechanism 4 and the groove pressing mechanism 5 are capable of moving according to the movement of the blocking mechanism 3 by setting the blocking mechanism 3, the knocking mechanism 4 and the groove pressing mechanism 5 in cooperation, the knocking assembly 41 is capable of knocking the charging barrel 001 when the blocking ring 31 in the blocking mechanism 3 moves upward, after the blocking mechanism 3 moves upward by a certain height, the groove pressing mechanism 5 pushes the powder out of a groove and fills into other powder.

[0069] In detail, the transmission mechanism 1 moves the charging barrel 001 to the lower end of the discharging mechanism 2, the discharging mechanism 2, the blocking mechanism 3 and the groove pressing mechanism 5 all move downward to the inside of the charging barrel 001, the discharging mechanism 2 discharges, after a certain amount of powder is released, the blocking ring 31 in the blocking mechanism 3 moves upward and the knocking mechanism 4 works, so as to avoid that the blocking ring 31 is hung with powder on the surface in the process of moving upward, the blocking ring 31 stops rising after moving upward by a certain height, the groove pressing mechanism 5 starts to work, pushes the powder out of a groove, pushes the powder to the two sides of the groove, so that the powder can fill into the gap left by the blocking ring 31 and fill other powder in the groove.

[0070] It should be noted that the thickness of the blocking ring 31 is very thin, which can tightly adhere to the inner side wall of the charging barrel 001, the powder is in a loose state after being discharged from the discharging mechanism 2, the groove left by the groove pressing mechanism 5 downward pressing extrudes the excess powder to the two sides, so that the powder fills into the gap left by the blocking ring 31, since the downward pressing of the groove pressing mechanism 5 will change the local density of the powder, therefore, the pressure applied by the groove pressing mechanism 5 should be less than the pressure generated by the isostatic pressing in the subsequent processing process.

[0071] It is worth mentioning that the blocking ring 31 is in a rotating state in the process of moving upward, and cooperates with the knocking of the knocking assembly 41 to the charging barrel 001, so that the blocking ring 31 tightly adhering to the inner side wall of the charging barrel 001 also vibrates, thereby avoiding that the blocking ring 31 is adhered with powder on the surface.

[0072] Further, the lifting unit 322 includes a lifting plate 3221 located below the rotating ring 321 and rotationally connected with the rotating ring 321, a plurality of lifting rods 3222 arranged in an array around the lifting plate 3221 and slidingly connected with the lifting plate 3221, a fixing frame 3223 located outside the lifting plate 3221 and used for fixing the lifting rods 3222, a threaded rod 3224 rotationally connected with the fixing frame 3223 and threadedly connected with the lifting plate 3221, and a first motor 3225 fixedly installed on the fixing frame 3223 and having an output shaft fixedly connected with the threaded rod 3224.

[0073] In the embodiment, the threaded rod 3224 is capable of driving the lifting plate 3221 to move up and down by setting the lifting plate 3221 in cooperation with the threaded rod 3224, and since the threaded rod 3224 has the characteristics of driving, the distance of the lifting plate 3221 moving up and down is easy to control and has high precision.

[0074] Specifically, the first motor 3225 drives the threaded rod 3224 to rotate, and the threaded rod 3224 drives the lifting plate 3221 to move up and down.

[0075] It should be noted that during the entire working process, the lifting plate 3221 needs to be lowered first and then raised in sections, so the first motor 3225 needs to be accurately controlled, and a motor of appropriate specifications needs to be selected.

[0076] It is worth mentioning that the threaded rod 3224 is driven by the motor to drive the lifting plate 3221 to move up and down, the working process is stable and reliable, and the up and down movement distance of the lifting plate 3221 is easy to control.

[0077] Further, the rotating unit 323 includes a first gear ring 3231 fixedly connected to the rotating ring 321, a first gear 3232 engaged with the first gear ring 3231, a first bevel gear 3233 fixedly connected to the first gear 3232, a second bevel gear 3234 engaged with the first bevel gear 3233, a second gear 3235 fixedly connected to the second bevel gear 3234, and a first rack 3236 engaged with the second gear 3235.

[0078] In this embodiment, by setting the first gear ring 3231 to cooperate with the first rack 3236, the rotation of the first gear ring 3231 can be associated with the lifting and lowering of the lifting plate 3221, so that the first gear ring 3231, the rotating ring 321 and the blocking ring 31 are driven to rotate when the lifting plate 3221 is lifted, reducing the amount of powder that the surface of the blocking ring 31 hangs when it is lifted.

[0079] Specifically, when the lifting plate 3221 is lowered, the second gear 3235 is driven to rotate, the second gear 3235 is moved downward relative to the first rack 3236 to rotate the second gear 3235, the second gear 3235 drives the second bevel gear 3234 to rotate, the second bevel gear 3234 drives the first bevel gear 3233 and the first gear 3232 to rotate, and the first gear 3232 drives the first gear ring 3231 and the rotating ring 321 to rotate.

[0080] It should be noted that the first rack 3236 is vertically fixedly installed on the fixed frame 3223.

[0081] It is worth mentioning that the rotation of the rotating ring 321 is associated with the up and down movement of the lifting plate 3221, and the transmission ratio can be adjusted through the gear and rack transmission to keep the rotation speed of the rotating ring 321 and the blocking ring 31 at an appropriate size, avoiding too small or too large rotation speed of the blocking ring 31, which affects the purpose of reducing the amount of powder hanging on the wall.

[0082] Further, the feeding mechanism 2 is fixedly installed on the lifting plate 3221, and the feeding mechanism 2 comprises a spraying machine 21 and a diffusion assembly 22, the diffusion assembly 22 comprises a flattening frame 221 rotatably connected to the outside of the spraying machine 21, a third gear 222 fixedly connected to the upper end of the flattening frame 221, a fourth gear 223 rotatably connected to the outer shell of the spraying machine 21 and engaged with the third gear 222, and a second motor 224 fixedly connected with the output shaft and the fourth gear 223.

[0083] In the embodiment, the flattening frame 221 is matched with the spraying machine 21, so that the flattening frame 221 can flatten the sprayed powder when the spraying machine 21 works, thereby avoiding powder accumulation and enabling the powder to be uniformly filled into the charging barrel 001.

[0084] In detail, when the spraying machine 21 works, the second motor 224 is started, the second motor 224 drives the fourth gear 223 to rotate, the fourth gear 223 drives the third gear 222 to rotate, the third gear 222 drives the flattening frame 221 to rotate, and the powder sprayed by the spraying machine 21 is accumulated below the flattening frame 221, so that the flattening frame 221 rotates to push the powder in the middle to the outside, so that the powder is more uniformly filled.

[0085] It should be noted that the lower end of the flattening frame 221 is provided with a plurality of arc-shaped scraping rods, which can push the excess powder when the rotating frame rotates, and the powder is pushed to the outside by centrifugal force, thereby avoiding the condition that the powder is high in the middle and low around.

[0086] It is worth mentioning that the flattening frame 221 makes the powder around more loose through rotation, thereby avoiding the adhesion between the powders, which affects the work of the subsequent groove pressing mechanism 5.

[0087] Further, the knocking mechanism 4 comprises a knocking assembly 41 and a control assembly 42;

[0088] The knocking assembly 41 comprises:

[0089] The knocking hammer 411 is provided with two groups of knocking hammers 411 above and below, and each group of knocking hammers 411 is fixedly connected, and the two groups of knocking hammers 411 are rotatably connected to the two ends of the rotating shaft;

[0090] The sliding block 412 is fixedly connected to the rotating shaft at one end and slidably connected to the transmission mechanism 1;

[0091] The movable rod 413 is used for fixedly connecting the two knocking hammers 411 above;

[0092] The connecting frame 414 is rotatably connected to the movable rod 413 at one end and provided with a sliding groove at the other end;

[0093] A push rod 415 is horizontally and slidingly connected to the sliding block 412 and slidingly connected to a sliding groove of the connecting frame 414 at one end of the connecting frame 414, and the push rod 415 slides up and down relative to the connecting frame 414;

[0094] A control rod 416 is slidingly connected to the middle of the push rod 415 at the upper end and rotatably connected to the sliding block 412 at the lower end;

[0095] A swing rod 417 is rotatably connected to a sliding block at the upper end, and the sliding block is slidingly connected to the middle of the control rod 416;

[0096] A first pulley 418 is fixedly connected to the lower end of the swing rod 417 and rotatably connected to the sliding block 412.

[0097] In this embodiment, the push rod 415 pushes the knocking hammer 411 to regularly knock the outer side wall of the charging barrel 001 through the cooperation of the knocking hammer 411, the sliding block 412, and the push rod 415, thereby causing the vibration of the charging barrel 001 and the blocking ring 31, so that the blocking ring 31 avoids the powder from adhering to the blocking ring 31 during movement.

[0098] In detail, the first pulley 418 rotates to drive the swing rod 417 to rotate, the sliding block on the swing rod 417 controls the control rod 416 to reciprocate, the control rod 416 reciprocates to drive the push rod 415 to horizontally reciprocate, the horizontal reciprocation of the push rod 415 drives the connecting frame 414 and the movable rod 413 to move, thereby realizing the back-and-forth swing of the knocking hammer 411 around the rotating shaft, and the knocking hammer 411 located at the upper end and the knocking hammer 411 located at the lower end knock the outer side wall of the charging barrel 001, respectively.

[0099] It should be noted that the knocking hammer 411, the movable rod 413, the connecting frame 414, the push rod 415, the control rod 416, the swing rod 417, and the first pulley 418 are all installed on the sliding block 412, and the knocking hammer 411 can only swing to knock the charging barrel 001 after the sliding block 412 slides to approach the charging barrel 001.

[0100] It is worth mentioning that two groups of four knocking hammers 411 are arranged to expand the knocking area, so that the vibration caused by knocking can be expanded to the charging barrel 001 on this side, and the placement of a single knocking hammer 411 is avoided to cause the charging barrel 001 to deform greatly and affect the distribution of the internal blocking ring 31 and the powder.

[0101] Further, the control assembly 42 comprises a sliding piece 421 for controlling the sliding of the sliding block 412 and a driving piece 422 for controlling the knocking of the knocking hammer 411. The sliding piece 421 comprises a second rack 4211 fixed on the sliding block 412, a fifth gear 4212 engaged with the second rack 4211, a worm wheel 4213 fixedly connected with the fifth gear 4212, a worm 4214 engaged with the worm wheel 4213, a third bevel gear 4215 fixedly connected above the worm 4214, a fourth bevel gear 4216 engaged with the third bevel gear 4215, a sixth gear 4217 fixedly connected with the fourth bevel gear 4216, and a third rack 4218 which can be engaged with the sixth gear 4217 and is fixedly connected on the lifting plate 3221.

[0102] In the embodiment, the sliding of the sliding block 412 is associated with the up-down movement of the lifting plate 3221 by setting the worm wheel 4213 and the worm 4214 in cooperation. When the lifting plate 3221 starts to descend, the sliding piece 421 drives the sliding block 412 to move close to the charging barrel 001, and before the lifting plate 3221 ends to ascend, the sliding piece 421 drives the sliding block 412 to move away from the charging barrel 001.

[0103] In detail, when the lifting plate 3221 starts to descend, the third rack 4218 fixed on the lifting plate 3221 also descends, the third rack 4218 engages the sixth gear 4217, the sixth gear 4217 rotates, the sixth gear 4217 drives the fourth bevel gear 4216 to rotate, the fourth bevel gear 4216 drives the third bevel gear 4215 to rotate, the third bevel gear 4215 drives the worm 4214 to rotate, the worm 4214 drives the worm wheel 4213 and the fifth gear 4212 to rotate, the fifth gear 4212 drives the second rack 4211 and the sliding block 412 to slide, the sliding block 412 slides to a predetermined position, the third rack 4218 continues to descend and disengages the sixth gear 4217, the position of the sliding block 412 is fixed, and before the lifting plate 3221 ends to ascend, the third rack 4218 engages the sixth gear 4217 again, the sixth gear 4217 reversely drives the sliding block 412 to move away from the charging barrel 001.

[0104] It should be noted that when the knocking mechanisms 4 on both sides of the transmission mechanism 1 are fixed, the charging barrel 001 may collide when moving on the transmission mechanism 1, which is not conducive to the production work. Therefore, the knocking mechanisms 4 on both sides need to be moved away when the charging barrel 001 moves to avoid collision.

[0105] It is worth mentioning that by adopting the transmission mode of the worm wheel 4213 and the worm 4214, a self-locking function is realized to a certain extent, which avoids that the reverse force of the knocking hammer 411 in the knocking process pushes the sliding block 412 away from the charging barrel 001, affecting the vibration effect.

[0106] Further, the driving member 422 comprises a second pulley 4221 connected with the first pulley 418 and rotatably connected to the sliding block 412, a ratchet wheel 4222 fixedly connected to the second pulley 4221, a seventh gear 4223 fixedly connected to the outer side of the ratchet wheel 4222, and a fourth rack 4224 fixedly connected to the lifting plate 3221 and capable of being engaged with the seventh gear 4223.

[0107] In the embodiment, the fourth rack 4224, the seventh gear 4223 and the ratchet wheel 4222 are matched to realize the association of the lifting plate 3221 and the knocking assembly 41, so that the lifting plate 3221 can drive the knocking assembly 41 to work when it moves up, and the knocking assembly 41 does not work when it moves down or is static, thereby reducing energy consumption.

[0108] In detail, when the lifting plate 3221 moves up, the fourth rack 4224 moves up to drive the seventh gear 4223 to rotate, and the seventh gear 4223 transmits power to the second pulley 4221 through the ratchet wheel 4222, and the second pulley 4221 drives the first pulley 418 to rotate through the transmission belt to drive the knocking assembly 41 to work. When the lifting plate 3221 moves down, the ratchet wheel 4222 cannot transmit power to the second pulley 4221, and the knocking assembly 41 does not work.

[0109] It should be noted that the second pulley 4221, the ratchet wheel 4222 and the seventh gear 4223 in the driving member 422 are all mounted on the sliding block 412, and when the sliding block 412 moves to a position close to the charging barrel 001, the seventh gear 4223 is located on the path of the up-and-down movement of the fourth rack 4224, and the seventh gear 4223 is engaged with the fourth rack 4224 as the fourth rack 4224 descends.

[0110] It is worth mentioning that the work of the knocking assembly 41 is associated with the lifting of the lifting plate 3221, so that the knocking assembly 41 only knocks the charging barrel 001 when the lifting plate 3221 and the blocking ring 31 are lifted, avoiding the vibration of the blocking ring 31 when it is not lifted, so that the powder in the inner side of the blocking ring 31 is squeezed, the gap caused by the blocking ring 31 is enlarged, and the working effect of the pressure groove mechanism 5 is affected.

[0111] Further, the pressure groove mechanism 5 comprises an executing member 51 and a pressing member 52, and the executing member 51 comprises

[0112] a limiting ring 511 which is annular and has an annular groove in the middle;

[0113] a limiting rod 512 which is fixedly connected to the limiting ring 511 at the lower end and fixedly connected to the rotating ring 321 at the upper end;

[0114] A pressing ring 513 is arranged in the annular groove of the limiting ring 511 and is in sliding connection with the limiting ring 511;

[0115] A connecting block 514 is fixedly connected to the pressing ring 513 and has an upper end in sliding connection with the limiting rod 512;

[0116] A spring 515 is sleeved on the limiting rod 512 and is located between the connecting block 514 and the limiting ring 511;

[0117] An extension frame 516 is fixedly connected to the upper end of the pressing ring 513 and has an annular upper end;

[0118] A material tank 517 is arranged on the pressing ring 513, and a material outlet of a material pipe is arranged on the pressing ring 513.

[0119] In the embodiment, the pressing ring 513 cooperates with the limiting ring 511 to extrude the powder, a groove is extruded from the flattened powder, and the pushed-away powder is filled into the gap left by the upward movement of the blocking ring 31, so that the powder in the loading barrel 001 is filled more fully.

[0120] In detail, the pressing ring 513 is controlled by the pressing member 52 to move downward to extrude the powder, and at the same time, the limiting ring 511 rotates with the rotating ring 321 to prevent the pressing ring 513 and the limiting ring 511 from being adhered to the powder, the pushed-away powder is extruded into the gap left by the upward movement of the blocking ring 31, the loading barrel 001 is filled fully, the pressing member 52 stops pressing the pressing ring 513, the pressing ring 513 is popped up by the spring 515, the groove is separated, the material tank 517 on the pressing ring 513 is opened, the material pipe releases other powder, the material tank 517 fills other powder into the groove with the rotation of the pressing ring 513, and the strength of the product is improved by cooperating with the subsequent pressure reduction step.

[0121] It should be noted that the pressing ring 513 is in sliding connection with the limiting ring 511, the pressing ring 513 can slide up and down relative to the limiting ring 511, and the contact position of the pressing ring 513 and the limiting ring 511 is closely attached to avoid the powder from being inserted into the gap between the two during the pressing process of the pressing ring 513.

[0122] It is worth mentioning that the limiting ring 511 is located on both sides of the pressing ring 513 to prevent the pressing ring 513 from causing the powder to rise when being pressed downward, so that the powder cannot be filled into the gap of the side wall.

[0123] Furthermore, the clamping member 52 includes a cam 521 arrayed above the extension frame 516 and rotatably connected to the lifting plate 3221, a fifth bevel gear 522 fixedly connected to the cam 521, a bevel ring 523 meshing with all the fifth bevel gears 522, a second tooth ring 524 fixedly connected to the bevel ring 523 and rotatably connected to the lifting plate 3221, an eighth gear 525 meshing with the second tooth ring 524, a third pulley 526 fixed above the eighth gear 525, and a fourth pulley 527 belt-connected to the third pulley 526 and fixedly connected to the first bevel gear 3233.

[0124] In this embodiment, by setting cam 521 to cooperate with bevel ring 523, the rotation of multiple cams 521 is synchronously controlled. The rotation of cam 521 controls the downward movement of pressure ring 513, thus associating the rotation of cam 521 shaft with the upward movement of lifting plate 3221.

[0125] In detail, when the lifting plate 3221 rises, the first bevel gear 3233 drives the fourth pulley 527 to rotate. The fourth pulley 527 drives the third pulley 526 and the eighth gear 525 to rotate via the transmission belt. The eighth gear 525 drives the second gear ring 524 and the bevel gear ring 523 to rotate. The bevel gear ring 523 drives all the fifth bevel gears 522 to rotate. The fifth bevel gears 522 drive the cam 521 to rotate. When the protruding part of the cam 521 rotates to the bottom, it presses down the extension frame 516, causing the pressure plate to move down and extrude the powder.

[0126] It should be noted that the protruding parts of all cams 521 should be kept on the same horizontal plane so that the extension frame 516 can remain vertically sliding down when pressed by the cams 521. At the same time, the transmission relationship between the rising height of the lifting plate 3221 and the rotation of the cam 521 should be adjusted so that the fixed height that the lifting plate 3221 rises each time makes the cam 521 rotate exactly one revolution. The initial position of the cam 521 should be located at the position where the extension frame 516 is about to be pressed down but has not yet been pressed down.

[0127] It is worth mentioning that, since the lifting plate 3221 is moving upward at this time, the extension frame 516 can be pressed down and disengaged quickly through the cam 521, reducing the time occupied by the pressing groove step.

6. The production process of a charging device for improving the performance of isostatic pressing products according to claim 5, characterized in that, Includes the following steps: Step 1: Preparation process. The material barrel (001) is moved to the bottom of the material feeding mechanism (2) and the enclosure mechanism (3) through the transmission mechanism (1). The lifting plate (3221) of the enclosure mechanism (3) drives the enclosure, the material feeding mechanism (2) and the pressing mechanism (5) to move down into the material barrel (001). The retaining ring (31) is close to the side wall of the material barrel (001). Step 2: Feeding process. The retaining ring (31) moves to the bottom of the loading barrel (001), and the feeding mechanism (2) starts feeding. The diffusion component (22) spreads the powder evenly in the loading barrel (001). After a certain amount of powder is fed, the lifting plate (3221) moves up, driving the feeding mechanism (2) and the retaining ring (31) to move up. During the upward movement, the rotating unit (323) controls the retaining ring (31) to rotate. At the same time, the hammer (411) in the striking unit strikes the outer surface of the loading barrel (001) under the action of the driving component (422), causing the loading barrel (001) and the retaining ring (31) to vibrate. With the rotation of the retaining ring (31), the retaining ring (31) is prevented from carrying away the powder during the upward movement. Step 3: Grooving process. When the lifting plate (3221) rises, the pressure ring (513) and the limiting ring (511) rotate synchronously under the drive of the rotating ring (321). The cam (521) in the clamping part (52) of the grooving mechanism (5) rotates under the action of the gear. The rotation of the cam (521) drives the extension frame (516) and the pressure ring (513) to move down. As the pressure ring (513) rotates, it moves down and pushes the powder out of a groove. At the same time, under the action of the limiting ring (511), the pushed powder fills the gap left in the loading bucket (001) after the inlet ring (31) is removed. As the cam (521) rotates, the pressure ring (513) bounces up under the action of the spring (515). At this time, the pressure ring (513) continues to rotate, and the material tank (517) opens to fill the groove with other powder.
