Description

Technical Field

[0001] The invention relates to the technical field of powder molding, and in particular to an automatic powder loading device for a conical mold. Background Art

[0002] Cold isostatic pressing (CIP) is a process at room temperature that uses rubber or plastic as the mold material and liquid as the pressure medium. It is mainly used for forming powder materials to provide a green body for further sintering, forging or hot isostatic pressing processes.

[0003] During the cold isostatic pressing process, metal powder needs to be loaded into the mold before the mold is placed in the pressure equipment. Different shapes of products will make the mold different, so the powder loading process will also have slight differences.

[0004] In the process of producing conical or other special-shaped pressed blanks by cold isostatic pressing, the powder is usually filled by manual compaction, that is, a fixed weight of metal powder is weighed and loaded from the loading port of the fixed conical (rubber sleeve and steel core) combination mold. The powder is first vibrated on a vibration platform. After most of the powder is filled, it is compacted and filled in small amounts multiple times, and the powder is compacted and filled repeatedly. Although the process of this manual powder filling method is relatively mature, different people use different forces and techniques to fill the powder, resulting in poor consistency in the powder filling quality. The shape of the combination mold after manual powder filling is irregular, the powder filling uniformity is poor, and manual powder filling is laborious and very inefficient.

[0031] Example

[0032] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 7As shown, the automatic powder loading device for the conical mold 112 in this embodiment includes an operating table 10, a support table 14 slidably arranged on the upper surface of the operating table 10, a support plate 19 arranged on the support table 14, a push rod 18 arranged below the support plate 19, an impact device for driving the push rod 18 to reciprocate in the vertical direction, a feeding device arranged at one end of the operating table 10, a powder pressing device arranged at the other end of the upper surface of the operating table 10, and a horizontal driving device for driving the support table 14 to move between the feeding device and the powder pressing device; the feeding device includes a bottom The base 22 comprises a vertical driving device for driving the base 22 to rise and fall, a powder bin 23 fixedly mounted on the base 22, a weighing device disposed below the outlet end of the powder bin 23, and a discharge hopper 26 disposed below the weighing device; the mold 112 is detachably fixed on the upper surface of the support plate 19; the weighing device and the discharge hopper 26 are both connected to the base 22; the powder pressing device comprises a first electric telescopic cylinder 42 and a bracket 41 for supporting the first electric telescopic cylinder 42, and a pressing head 43 disposed at the end of the first electric telescopic cylinder 42; the pressing head 43 is arranged downward. Specifically, when in use, the metal powder is first poured into the powder bin 23, and then the powder in the powder bin 23 is discharged into the weighing device as needed. After the weighing device weighs a certain amount of powder, the powder is discharged into the discharge hopper 26 below, and then the powder is discharged into the mold 112 below through the discharge hopper 26. Since the opening of the conical mold 112 is very small, a vertical drive device is required to drive the base 22 to move downward as a whole (the discharge hopper 26 is fixedly connected to the base 22, so it will move with the movement of the base 22), so that the end of the discharge hopper 26 is fully aligned with the entrance of the mold 112 before the powder is discharged into the mold 112, and then the vertical drive device drives the base 22 to move upward. At this time, the impact device is turned on, and the impact device repeatedly lifts the push rod 18, and the push rod 18 then lifts the support plate 19 and the mold 112. During the falling process of the mold 112, it hits the support platform 14 to compact the powder in the mold 112 (as shown in the attached figure). Figure 5-6 Therefore, artificial vibration is simulated), and the process is repeated to effectively compact the powder in the mold 112. In addition, the powder can be discharged into the mold 112 in batches to achieve batch compaction, thereby achieving a better compaction effect, making the powder distribution more uniform and the density better. In the later stage of powder filling, the operating table 10 can also be moved to the powder pressing device (such as the attached Figure 2 As shown in the figure, the first electric telescopic cylinder 42 in the powder pressing device pushes the pressing head 43 into the mold 112 to compact the powder in the mold 112, and then repeats the steps of powder filling, vibration, and compaction. Finally, a relatively ideal powder filling effect is achieved. In addition, the device can be fully automated, the operation process is more standardized than manual, and the quality of the finished product is more uniform. It should be noted that a screw feeder can be set at the bottom of the powder bin 23 to quantitatively discharge the material.

[0033] The feeding device in this embodiment also includes a shaking material plate 24 disposed between the powder bin 23 and the weighing device; the side of the shaking material plate 24 close to the weighing device is an open side; the open side of the shaking material plate 24 is disposed directly above the weighing device; the shaking material plate 24 is connected to a first vibration motor 25. Specifically, after a certain amount of material in the powder bin 23 is discharged according to a set program, the shaking material plate 24 is driven to vibrate continuously by the first vibration motor 25, so that the powder slowly enters the weighing device from the open side of the shaking material plate 24, so that the amount of powder entering the weighing device can be well controlled to avoid exceeding the predetermined amount. The height of the open side of the shaking material plate 24 needs to be slightly lower than the other side, so as to facilitate the flow of powder.

[0034] The weighing device in this embodiment includes a weighing device arranged inside the base 22, a connection frame 311 connected to the weighing device, a weighing box 31 with an opening at the lower end, a baffle hinged at the lower end of the weighing box 31, and an opening and closing driving device for driving the baffle to open and close; the end of the connection frame 311 away from the weighing device passes through the base 22 and is fixedly connected to the weighing box 31 through the connection plate 32; the upper end of the weighing box 31 is arranged directly below the shaking plate 24, and the lower end of the weighing box 31 is arranged directly above the discharge hopper 26. Specifically, the weighing device can be regarded as a part for measuring, and the weighing box 31 can be regarded as a tray structure for accommodating powder. The weighing device and the weighing box 31 are arranged horizontally, so that the powder can be better discharged into the discharge hopper 26 below after being weighed.

[0035] The baffle in this embodiment includes a first baffle 33 and a second baffle 34 respectively arranged on opposite sides of the lower end of the weighing box 31; the opening and closing driving device includes a first connecting rod 35 fixedly connected to the first baffle 33, a second connecting rod 37 fixedly connected to the second baffle 34, a third connecting rod 39 for connecting the first connecting rod 35 and the second connecting rod 37, a pull rod 310 connected to the second baffle 34, a pair of triangular plates 312 respectively hinged to opposite sides of the connecting frame 311, a fixing rod 313 for connecting the pair of triangular plates 312, a first driving motor 314 arranged inside the base 22, and an L-shaped shifting rod 315; the middle of the first connecting rod 35 is provided with a There is a first rotating shaft 36, and the first connecting rod 35 is hinged to the outer wall of the weighing box 31 through the first rotating shaft 36; a second rotating shaft 38 is provided in the middle of the second connecting rod 37, and the second connecting rod 37 is hinged to the outer wall of the weighing box 31 through the second rotating shaft 38; one end of the third connecting rod 39 is hinged to the first connecting rod 35, and the other end is hinged to the second connecting rod 37; the end of the pull rod 310 away from the second baffle 34 is hinged to one of the triangular plates 312, the output shaft of the first drive motor 314 passes through the side wall of the base 22 and is arranged in the connecting frame 311, and the lever 315 is fixedly connected to the output shaft of the first drive motor 314; the lever 315 is used to move the fixed rod 313 up and down. Specifically, as shown in the attached Figure 4 and attached Figure 7 As shown, the specific operation steps of the structure are as follows: the first driving motor 314 rotates, causing the lever 315 to rotate. During the rotation of the lever 315, the lower side of the fixed rod 313 is supported and lifted upward. The upward movement of the fixed rod 313 causes the triangular plate 312 to rotate along the hinge with the connecting frame 311, thereby pulling the pull rod 310 to move upward. The pull rod 310 directly pulls open the second baffle 34, and the second baffle 34 pulls open the first baffle 33 through the three-link structure formed by the first connecting rod 35, the second connecting rod 37 and the third connecting rod 39. In this way, the powder in the weighing box 31 is discharged into the discharge hopper 26. In this process, the weighing box 31, the first baffle 33, the second baffle 34, the first connecting rod 35, the second connecting rod 37, the third connecting rod 39, the connecting plate 32, the pull rod 310, the triangular plate 312 and other structures are directly or indirectly connected to the connecting frame 311, so the weighing machine directly weighs the total weight of the above structures. And when the baffle does not need to be opened, the lever 315 will not be connected to the fixed rod 313, so the first drive motor 314 and the lever 315 will not affect the weighing of the weighing machine, making the weighing more accurate.

[0036] The opening and closing driving device in this embodiment further includes a spring 316, one end of which is connected to the triangular plate 312, and the other end is connected to the connecting frame 311. Specifically, although the baffle can be pressed back by the weight of the triangular plate 312, the fixing rod 313 and the pull rod 310, the spring 316 is used to pull the triangular plate 312, and the triangular plate 312 and the fixing rod 313 can more stably support the baffle to avoid leakage.

[0037] The outer wall of the discharge hopper 26 in this embodiment is fixedly connected with a second vibration motor 27, and the second vibration motor 27 is fixedly connected to the base 22. Specifically, since the fluidity of metal powder is not strong, the second vibration motor 27 is arranged on the outer wall of the discharge hopper 26 to better shake the powder into the mold 112. In addition, the second vibration motor 27 can be started intermittently as needed to discharge the material in the discharge hopper 26 into the mold 112 in batches.

[0038] In this embodiment, a slide groove 15 is provided on the side of the support platform 14, and a slide rail 11 is provided on the operating platform 10; the slide groove 15 cooperates with the slide rail 11; a plurality of slide bars 110 are fixedly provided on the upper surface of the support platform 14, and a plurality of slide holes are provided on the support plate 19, and a slide bar 110 is slidably provided in a slide hole. Specifically, the cooperation between the slide rail 11 and the slide groove 15 makes the operation of the support platform 14 more stable. The cooperation between the slide bar 110 and the slide hole enables the support plate 19 to move up and down more stably and smoothly.

[0039] In this embodiment, a plurality of buffer blocks 111 are fixedly disposed on the lower surface of the support plate 19. Specifically, the buffer blocks 111 may be made of hard rubber material, so as to avoid a hard collision between the support plate 19 and the support platform 14, which causes the support plate 19 to bounce on the support platform 14, thereby loosening the powder in the mold 112.

[0040] The impact device in this embodiment includes a second drive motor 12 disposed below the support platform 14, and an eccentric wheel 13 disposed on the output shaft of the second drive motor 12. Specifically, the eccentric wheel 13 is preferably a combination of two semicircles with different diameters, so that the effect of slowly lifting the push rod 18 and the support plate 19 and then suddenly dropping them can be well achieved.

[0041] The horizontal drive device in this embodiment includes a third drive motor 16 fixedly connected to the support platform 14, and a gear 17 arranged on the output shaft of the third drive motor 16. The operating table 10 is provided with a rack along the length direction, and the gear 17 is meshed with the rack; it also includes a vertically arranged housing 21, and a base 22 is slidably arranged at the upper end of the housing 21; the vertical drive device includes a second electric telescopic cylinder arranged inside the housing 21 (not shown in the drawings); the telescopic rod of the second electric telescopic cylinder is connected to the base 22. Specifically, since the mold 112 needs to be able to accurately align with the discharge hopper 26 or the pressure head 43, the third drive motor 16 needs to use a servo motor with higher operating accuracy.

[0042] In summary, the automatic powder loading device of the conical mold 112 of the present embodiment can effectively compact the powder in the mold 112. In addition, the powder can be discharged into the mold 112 in batches to achieve batch compaction, so as to achieve a better compaction effect, and make the powder distribution more uniform and the density better. In the later stage of powder loading, the operating table 10 can also be moved to the powder pressing device by a horizontal drive device, and the first electric telescopic cylinder 42 in the powder pressing device pushes the pressure head 43 to be pressed into the mold 112, and the powder in the mold 112 is compacted, and then the steps of filling powder, vibrating, and compacting are repeated. Finally, a more ideal powder filling effect is achieved. And the device can be fully automated, the operation process is more standardized than manual, and the quality of the finished product produced is more uniform.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
