Description

Technical Field

[0001] The utility model belongs to the technical field of explosive column pressing production, in particular to an isostatic pressing system mold inlet and outlet cylinder hanging basket structure. Background Art

[0002] Due to the unique nature of the raw materials, traditional explosive charges are pressed using a hydraulic press with a die. This results in low production efficiency and allows only a single shot to be pressed at a time. The hydraulic press applies upward and downward force during pressing, resulting in a bulky and heavy die. Furthermore, the press is limited by the coaxiality and parallelism of the upper and lower dies, as well as the low control precision of large hydraulic presses. This can lead to uneven pressing force and unstable product quality. Using isostatic pressing to press explosive charges allows for the production of multiple shots at a time. Furthermore, the product is subjected to omnidirectional force, resulting in balanced force, stable quality, and a lightweight die.

[0003] But how to place the isostatic pressing mold into the cylinder body is an urgent problem to be solved. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a hanging basket structure for molds entering and exiting a cylinder in an isostatic pressing system.

[0005] The technical solution adopted by this utility model is:

[0006] A hanging basket structure for molds entering and exiting an isostatic pressing system includes a workbench with an isostatic pressing cylinder body installed in the workbench, an upper lifting mechanism is provided on the upper side of the workbench, the output end of the upper lifting mechanism is connected to a high-pressure upper head for sealing the upper opening of the isostatic pressing cylinder body, and a high-pressure lower head is provided on the lower side of the isostatic pressing cylinder body; a transverse driving mechanism is installed on the workbench, the output end of the transverse driving mechanism is connected to a hanging basket slide, and several layers of hanging baskets hung in sequence are placed on the hanging basket slide, the hanging baskets are used to place filled molds, and the topmost hanging basket is hung with the high-pressure upper head.

[0007] According to the depth of the isostatic cylinder and the height of the mold, different layers of hanging baskets are set up, and the layers are hung together. Before isostatic pressing, the mold and the hanging baskets are stacked layer by layer on the hanging basket slide. After the hanging baskets are stacked, the lateral drive mechanism drives the hanging basket slide to move horizontally, and the hanging basket is transferred to the top of the isostatic cylinder. Then the topmost hanging basket is hung with the high-pressure upper head. The upper lifting mechanism drives the high-pressure upper head upward, lifts the hanging basket, and moves the hanging basket slide out. The high-pressure upper head and the high-pressure lower head are respectively closed with the isostatic cylinder, and the hanging basket is encapsulated in the isostatic cylinder for isostatic pressing. After the molding is completed, the upper lifting mechanism lifts the hanging basket and transports the basket out through the hanging basket slide.

[0008] The utility model is characterized by the adjacent hanging baskets being connected, so that multiple hanging baskets can be sent into the isostatic cylinder at once, and multiple molds can be placed in each hanging basket, so that enough molds can be isostatically pressed at one time. The topmost hanging basket can be hung on the lower side of the high-pressure upper head, and the transverse driving mechanism can drive the multi-layer hanging baskets to move above the isostatic cylinder, and automatically connect the topmost hanging basket with the high-pressure upper head. When the upper lifting mechanism lowers the high-pressure upper head, several hanging baskets are sent into the isostatic cylinder. The mold-into-cylinder process is automatic, without the need for manual operation, and ensures the accuracy of the mold being sent in.

[0009] As a preferred solution of the present invention, a plurality of connecting lugs are provided on the upper side of the hanging basket, a partition is provided at the bottom of the hanging basket, a plurality of waist-shaped connecting holes are provided on the partition, and the connecting lugs on the lower hanging basket are hung with the waist-shaped connecting holes of the upper hanging basket.

[0010] The connecting lugs consist of a rounded cone, and the waist-shaped connecting holes consist of interconnected large and small holes. The diameter of the rounded cone is smaller than that of the large hole, and the diameter of the small hole is smaller than the diameter of the rounded cone. When connecting adjacent hanging baskets, the rounded cone of the lower hanging basket is inserted into the large hole of the upper hanging basket. After the two hanging baskets are rotated relative to each other by a certain angle, the rounded cone moves to the small hole, thus connecting the two hanging baskets.

[0011] As a preferred solution of the present invention, the partition is provided with a plurality of through holes. During the isostatic pressing process, high-pressure oil on the lower side of the hanging basket can enter the lower side of the mold through the through holes, thereby ensuring the same oil pressure everywhere.

[0012] As a preferred embodiment of the present invention, the top of the uppermost hanging basket is provided with a hanging lug, and a hanging platform is provided on the underside of the high-pressure upper head, to which the hanging lug is attached. The high-pressure upper head is provided with a pair of hooks with positioning slots formed on them to form a hanging platform. When the hanging basket slide moves, the hanging lug on the uppermost hanging basket slides directly into the hanging platform, connecting the hanging basket to the high-pressure upper head.

[0013] As a preferred embodiment of the present invention, the transverse drive mechanism includes a transverse drive motor mounted on a workbench. A lead screw is connected to the output end of the transverse drive motor, which is threadedly connected to the hanging basket slide. When the transverse drive motor rotates the lead screw, the lead screw drives the hanging basket slide in a linear motion. This lead screw can move multiple layers of hanging baskets to a specific position, and during this movement, the topmost hanging basket can automatically connect to the high-pressure upper head.

[0014] As a preferred solution of the present invention, the screw is staggered with the upper opening of the isostatic cylinder body to avoid the screw blocking the high-pressure upper head, ensuring that several layers of hanging baskets can be accurately delivered to the isostatic cylinder body, and ensuring that the high-pressure upper seal body can reliably seal the upper opening of the isostatic cylinder body.

[0015] As a preferred embodiment of the present invention, the hanging basket slide is slidably connected to the workbench. The hanging basket slide is provided with a placement groove, and the lowermost hanging basket is placed in the placement groove. The hanging basket slide can slide freely on the workbench, ensuring the stability of the hanging basket slide. The placement groove limits the hanging basket, ensuring the stable position of the hanging basket on the hanging basket slide.

[0016] As a preferred embodiment of the present invention, the upper lifting mechanism includes an upper hydraulic press, the high-pressure upper head is connected to the lower side of the upper hydraulic press, and the workbench is connected to the upper guide column, on which the upper hydraulic press is mounted. The upper hydraulic press can drive the high-pressure upper head to raise and lower, does not interfere with the hanging basket when it is moved into the hanging basket, and can accurately drive the high-pressure upper head to seal the isostatic cylinder after it is placed in the hanging basket.

[0017] As a preferred embodiment of the present invention, the high-pressure lower head is connected to a lower hydraulic mechanism, which includes a lower hydraulic press. The high-pressure lower head is connected to the upper side of the lower hydraulic press, and the workbench is connected to a lower guide post, which the lower hydraulic press is mounted on. The lower hydraulic press drives the high-pressure lower head to rise and fall, thereby driving the high-pressure upper head to accurately seal the lower opening of the isostatic cylinder.

[0018] As a preferred embodiment of the present invention, after the high-pressure upper and lower heads respectively seal the two sides of the isostatic cylinder, a gap is left between the lowest hanging basket and the high-pressure lower head. This ensures that high-pressure oil can flow freely within the isostatic cylinder, ensuring uniform oil pressure throughout the isostatic cylinder and facilitating oil return. A sensor is installed within the isostatic cylinder to prevent interference when a gap is left between the bottom of the lowest hanging basket and the high-pressure lower head.

[0019] The beneficial effects of the utility model are:

[0020] The utility model is characterized by the adjacent hanging baskets being connected, so that multiple hanging baskets can be sent into the isostatic cylinder at once, and multiple molds can be placed in each hanging basket, so that enough molds can be isostatically pressed at one time. The topmost hanging basket can be hung on the lower side of the high-pressure upper head, and the transverse driving mechanism can drive the multi-layer hanging baskets to move above the isostatic cylinder, and automatically connect the topmost hanging basket with the high-pressure upper head. When the upper lifting mechanism lowers the high-pressure upper head, several hanging baskets are sent into the isostatic cylinder. The mold-into-cylinder process is automatic, without the need for manual operation, and ensures the accuracy of the mold being sent in. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0031] like Figures 1 to 7As shown, the isostatic pressing system mold in-and-out cylinder basket structure of this embodiment includes a workbench 1, an isostatic pressing cylinder body 2 is installed in the workbench 1, an upper lifting mechanism 3 is provided on the upper side of the workbench 1, and the output end of the upper lifting mechanism 3 is connected to a high-pressure upper head 21 for sealing the upper opening of the isostatic pressing cylinder body 2, and a high-pressure lower head 22 is provided on the lower side of the isostatic pressing cylinder body 2; a transverse driving mechanism 4 is installed on the workbench 1, and the output end of the transverse driving mechanism 4 is connected to a basket slide 5, and several layers of hanging baskets 6 are placed on the basket slide 5, and the hanging basket 6 is used to place the filled mold 7, and the topmost hanging basket 6 is hung with the high-pressure upper head 21.

[0032] According to the depth of the isostatic cylinder 2 and the height of the mold 7, different layers of hanging baskets 6 are set, and the layers are connected. Before isostatic pressing, the mold 7 and the hanging basket 6 are stacked layer by layer on the hanging basket slide 5. After the hanging basket 6 is stacked, the lateral drive mechanism 4 drives the hanging basket slide 5 to move horizontally, and the hanging basket 6 is transported to the top of the isostatic cylinder 2. Then the topmost hanging basket 6 is connected to the high-pressure upper head 21. The upper lifting mechanism 3 drives the high-pressure upper head 21 upward, lifts the hanging basket 6, and moves the hanging basket slide 5 out. The high-pressure upper head 21 and the high-pressure lower head 22 are respectively closed with the isostatic cylinder 2, and the hanging basket 6 is encapsulated in the isostatic cylinder 2 for isostatic pressing. After the molding is completed, the upper lifting mechanism 3 lifts the hanging basket 6 and transports the hanging basket 6 out through the hanging basket slide 5.

[0033] The adjacent hanging baskets 6 of the present invention are connected, and multiple hanging baskets 6 can be sent into the isostatic cylinder 2 at once, and multiple molds 7 are placed in each hanging basket 6, so that enough molds 7 can be isostatically pressed at one time. The uppermost hanging basket 6 can be hung on the lower side of the high-pressure upper head 21, and the transverse driving mechanism 4 can drive the multi-layer hanging baskets 6 to move above the isostatic cylinder 2, and automatically connect the uppermost hanging basket 6 with the high-pressure upper head. When the upper lifting mechanism 3 lowers the high-pressure upper head 21, several hanging baskets 6 are sent into the isostatic cylinder 2. The process of the mold 7 entering the cylinder is automatic, without the need for manual operation, and ensures the accuracy of the mold 7 being sent into the cylinder.

[0034] Specifically, a plurality of connecting ears 61 are provided on the upper side of the hanging basket 6, a partition 62 is provided at the bottom of the hanging basket 6, and a plurality of waist-shaped connecting holes 63 are provided on the partition 62. The connecting ears 61 on the lower hanging basket 6 are hung with the waist-shaped connecting holes 63 of the upper hanging basket 6.

[0035] The connecting lug 61 includes a truncated cone, and the waist-shaped connecting hole 63 includes a large hole and a small hole that are interconnected. The diameter of the truncated cone is smaller than the diameter of the large hole, and the diameter of the small hole is smaller than the diameter of the cone. When connecting adjacent hanging baskets 6, the truncated cone of the lower hanging basket 6 is inserted into the large hole of the upper hanging basket 6. After the two hanging baskets 6 are rotated relative to each other by a certain angle, the truncated cone moves to the small hole, thereby connecting the two hanging baskets 6.

[0036] The partition plate 62 is provided with a plurality of through holes 64. During the isostatic pressing process, the high-pressure oil on the lower side of the hanging basket 6 can enter the lower side of the mold 7 through the through holes 64, thereby ensuring that the oil pressure is the same everywhere.

[0037] The top of the uppermost hanging basket 6 is provided with a hanging lug 65, and a hanging platform 211 is provided on the lower side of the high-pressure upper head 21. The hanging lug 65 is hung on the hanging platform 211. The high-pressure upper head 21 is provided with a pair of hooks with positioning grooves on them, forming the hanging platform 211. When the hanging basket slide 5 moves, the hanging lug 65 on the uppermost hanging basket 6 slides directly into the hanging platform 211, thus connecting the hanging basket 6 with the high-pressure upper head 21.

[0038] Specifically, the transverse drive mechanism 4 includes a transverse drive motor 41 mounted on the workbench 1. The output end of the transverse drive motor 41 is connected to a lead screw 42, which is threadedly connected to the hanging basket slide 5. When the transverse drive motor 41 drives the lead screw 42 to rotate, the lead screw 42 drives the hanging basket slide 5 to move linearly. Driven by the lead screw 42, multiple layers of hanging baskets 6 can be moved to a predetermined position, and the topmost hanging basket 6 can be automatically connected to the high-pressure upper head 21 during the movement.

[0039] It should be noted that the screw 42 is staggered with the upper opening of the isostatic cylinder 2 to prevent the screw 42 from blocking the high-pressure upper head 21, ensure that several layers of hanging baskets 6 can be accurately delivered to the isostatic cylinder 2, and ensure that the high-pressure upper head can reliably seal the upper opening of the isostatic cylinder 2.

[0040] The hanging basket slide 5 is slidably connected to the workbench 1. The hanging basket slide 5 is provided with a placement groove 51, and the lowermost hanging basket 6 is placed in the placement groove 51. The hanging basket slide 5 can slide freely on the workbench 1, ensuring the stability of the hanging basket slide 5. The placement groove 51 limits the hanging basket 6, ensuring that the position of the hanging basket 6 on the hanging basket slide 5 is stable.

[0041] Specifically, the upper lifting mechanism 3 includes an upper oil press 31, the high-pressure upper head 21 is connected to the lower side of the upper oil press 31, and the workbench 1 is connected to an upper guide column 32, and the upper oil press 31 is sleeved on the upper guide column 32. The upper oil press 31 can drive the high-pressure upper head 21 to rise or lower, and does not interfere with the hanging basket 6 when it is moved into the hanging basket 6. After being placed in the hanging basket 6, it can accurately drive the high-pressure upper head 21 to seal the isostatic cylinder 2.

[0042] The high-pressure lower end cap 22 is connected to a lower hydraulic mechanism 8. The lower hydraulic mechanism 8 comprises a lower hydraulic press 81. The high-pressure lower end cap 22 is connected to the upper side of the lower hydraulic press 81. The workbench 1 is connected to a lower guide post 82, on which the lower hydraulic press 81 is sleeved. The lower hydraulic press 81 drives the high-pressure lower end cap 22 upward and downward, thereby driving the high-pressure upper end cap 21 to accurately seal the lower opening of the isostatic cylinder 2.

[0043] It should be noted that after the high-pressure upper head 21 and the high-pressure lower head 22 respectively seal the two sides of the isostatic cylinder 2, a gap is left between the bottommost hanging basket 6 and the high-pressure lower head 22 to ensure that the high-pressure oil can flow freely within the isostatic cylinder 2, ensuring that the oil pressure is consistent throughout the isostatic cylinder 2 and facilitating oil return. A sensor is installed within the isostatic cylinder 2, and when a gap is left between the bottom of the bottommost hanging basket 6 and the high-pressure lower head 22, interference can be avoided.

[0044] The present invention is not limited to the above-mentioned optional implementation methods. Anyone can derive various other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention shall fall within the scope of protection of the present invention.
