DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0026] like Figures 1 to 5 As shown, the utility model provides a cemented carbide cold isostatic pressing device with automatic loading and unloading, comprising a hydraulic mechanism 1, a crane 2 and at least one carrier 3, the crane 2 comprising a rotating mechanism 21, a lifting mechanism 22 and a hook 23, the rotating mechanism 21 is used to drive the hook 23 to rotate in a horizontal plane, the lifting mechanism 22 is used to drive the hook 23 to lift and lower, the hook 23 is used to pick up the carrier 3, the carrier 3 is used to accommodate the alloy, the hydraulic mechanism 1 is used to accommodate the carrier 3 and perform isostatic pressing on the alloy in the carrier 3.

[0027] When the utility model is in operation, the number of carriers 3 is preferably more than two, that is, after the staff puts the alloy into the carrier 3, the carrier 3 is lifted by the hook 23, and then the carrier 3 is driven to rise by the lifting mechanism 22, and then the rotating mechanism 21 rotates to the oil pressure mechanism 1, and then the lifting mechanism 22 drives the carrier 3 to descend, thereby achieving the effect of placing the carrier 3 into the cold isostatic pressing mechanism 1; while the oil pressure is being applied, the staff can take and place the alloy from another carrier 3, thereby further improving efficiency.

[0028] The utility model adopts a crane 2 to realize the transfer of the carrier 3, realizes the effect of automatically loading and unloading the carrier 3 to the hydraulic mechanism 1, and improves the efficiency.

[0029] In this embodiment, the crane 2 further includes a translation mechanism 24 , which is disposed at the output end of the lifting mechanism 22 , the lifting mechanism 22 is disposed at the output end of the translation mechanism 24 , and the hook 23 is disposed at the output end of the lifting mechanism 22 .

[0030] That is, the hook 23 is driven by the translation mechanism 24 to translate, thereby achieving the effect of lifting the carrier 3 and leaving the carrier 3; at the same time, through the cooperation of the translation mechanism 24, the rotation mechanism 21 and the lifting mechanism 22, the movement path of the hook 23 is more flexible, and the spatial layout of the carrier 3 and the hydraulic mechanism 1 is more flexible.

[0031] It should be noted that the lifting mechanism 22, the rotating mechanism 21 and the translation mechanism 24 described in this embodiment are all conventional structures and will not be described in detail herein.

[0032] In this embodiment, the hydraulic mechanism 1 includes a container 11, a top cover 12, a lifting module 13, a limit cover 14, a translation module 15 and an oil circuit module 16. The container 11 is used to accommodate the vehicle 3 and the hydraulic oil. The top cover 12 is used to cover the top opening of the container 11. The lifting module 13 is used to drive the top cover 12 to rise and fall. The oil circuit module 16 is arranged between the top cover 12 and the container 11. The oil circuit module 16 is used to transmit the hydraulic oil in the container 11. The translation module 15 is used to drive the limit cover 14 to translate. The limit cover 14 is used to press the top cover 12 when the top cover 12 covers the container 11.

[0033] When the hydraulic mechanism 1 is in action, the translation module 15 drives the limit cover 14 to move away from the top of the top cover 12, and then the lifting module 13 drives the top cover 12 to rise, so that the crane 2 can pick up and place the carrier 3 in the container 11; after the picking and placing is completed, the lifting module 13 drives the top cover 12 to cover the container 11 again, and then the translation module 15 controls the limit cover 14 to move again to the top of the top cover 12. At this time, the oil circuit module 16 works, and the oil circuit module 16 injects hydraulic oil into the container 11 through the top cover 12. Since a larger pressure is required, when the hydraulic oil in the container 11 is full, the oil circuit module 16 still has a tendency to inject hydraulic oil into the container 11 to ensure that the internal pressure of the container 11 is sufficient. At this time, the limit cover 14 presses against the top of the top cover 12, and the braking force of the lifting module 13 and the pressure of the limit cover 14 ensure that the top cover 12 will not be flushed open by the hydraulic oil.

[0034] Specifically, the lifting module 13 is a linear swing combination cylinder, that is, when the lifting module 13 rises to a certain height, it will rotate as the oil is injected, so that the top cover 12 can achieve the effect of first rising and then rotating, so that enough space can be left for the crane 2 to take and place the carrier 3 in the container 11.

[0035] Specifically, the hydraulic mechanism 1 also includes a recovery station 17, which is connected to the oil circuit module 16. The recovery station 17 is provided with a supporting mesh plate 18, which is used to support the carrier 3 and allow the hydraulic oil on the carrier 3 to flow to the oil circuit module 16 through the mesh holes of the mesh plate.

[0036] That is, the carrier 3 just taken out of the container 11 must be attached with hydraulic oil. At this time, the crane 2 places the carrier 3 on the recovery station 17, allowing the hydraulic oil to fall under the action of gravity, and then enter the oil circuit module 16 through the mesh of the supporting mesh plate 18, achieving the recovery effect.

[0037] It should be noted that the oil circuit module 16 of the present invention has a conventional structure and will not be described in detail herein.

[0038] In this embodiment, the carrier 3 includes a frame 31. Along the height direction of the frame 31, a plurality of trays 32 are arranged in the frame 31 at intervals. The trays 32 are provided with sponges 33. The sponges 33 are used to hold the alloy. A detachable mounting structure 34 is provided between the trays 32 and the frame 31. The mounting structure 34 is used to support the trays 32.

[0039] When in use, the staff places the alloy on the sponge 33 of the tray 32, and the sponge 33 supports the alloy; then the crane 2 picks up the frame 31 and puts the frame 31 into the container 11, and then the oil circuit module 16 injects hydraulic oil into the container 11 and pressurizes it, so that all alloys are immersed in the oil and are continuously pressurized by the oil, so as to achieve the effect of making the internal density of the alloy uniform through the oil pressure; because the sponge 33 can absorb oil, part of the hydraulic oil contacts the alloy through the sponge 33, so that the contact surface between the alloy and the sponge 33 will also be pressurized, ensuring that the alloy is pressurized in all directions; after the oil pressure ends, the robot only needs to pick up the frame 31 to take out all the alloys together, thereby improving efficiency.

[0040] In this embodiment, the mounting structure 34 includes at least three screws 341 screwed to the frame 31, the ends of the screws 341 protrude into the frame 31, and the at least three screws 341 cooperate to hold the tray 32. That is, the staff can increase or decrease the tray 32 by disassembling the screws 341 as needed, so as to adjust the number of alloys of the utility model to be placed at one time according to the height of the alloy and make the utility model adapt to the height of the alloy, so that the application of the utility model is more flexible.

[0041] Specifically, the frame 31 includes a bottom plate 311, a top plate 312, and at least three connecting columns 313. The two ends of the connecting columns 313 are fixedly connected to the bottom plate 311 and the top plate 312, respectively. The plurality of trays 32 are located between the bottom plate 311 and the top plate 312. Along the height direction of the frame 31, the connecting columns 313 are provided with n screw holes 314 at intervals, and the screws 341 are screwed to the screw holes 314.

[0042] n is a natural number and n>1.

[0043] Specifically, the optimal number of screw holes 314 is 10-20, which can ensure that the strength of the connecting column 313 is not greatly affected. By setting as many screw holes 314 as possible, the height and number of the tray 32 can be more flexible.

[0044] That is, the staff can adjust the distance between adjacent trays 32 to achieve adaptation in addition to disassembling the tray 32 according to the height of the alloy. At the same time, the number of the connecting columns 313 is at least three because the triangle has stability. Only when there are more than two connecting columns 313, the number of screws 341 supporting the tray 32 is guaranteed to be sufficient, so that the tray 32 can be prevented from tipping over or moving under the action of oil.

[0045] Specifically, a sponge 33 is disposed on the top of the bottom plate 311 , that is, the bottom plate 311 not only serves as one of the skeleton structures of the frame 31 , but is also used to place the alloy.

[0046] Specifically, the frame 31 is provided with a lifting ring 315, specifically, the top of the top plate 312 of the frame 31 is fixedly connected with the lifting ring 315, and the lifting ring 315 is used to allow an external manipulator to pass through to drive the frame 31 to move. The lifting ring 315 is an upright structure, and the staff can use the crane 2 to hook the lifting ring 315 to achieve the picking up and moving of the utility model, so as to ensure that there is enough force to stably transfer the utility model with the alloy placed therein.

[0047] Specifically, the bottom plate 311 , the top plate 312 and at least three connecting columns 313 are fixed by welding, thereby ensuring the overall stability of the frame 31 and preventing it from falling apart.

[0048] Specifically, the sponge 33 is detachably mounted on the top of the tray 32, and the sponge 33 is provided with a clearance groove 331 for making way for the connecting column 313. The width or diameter of the tray 32 can be small, so that it can be stably placed in the tray 32; and the width of the sponge 33 is preferably larger than that of the tray 32, that is, the sponge 33 can be partially extended out of the frame 31 to achieve a limiting effect, and prevent the sponge 33 from easily detaching from the tray 32 and the frame 31.

[0049] In this embodiment, the tray 32 is provided with a plurality of through holes 321 for allowing the oil to pass through and enter the interior of the sponge 33 , thereby penetrating the sponge 33 and contacting the alloy.
