Description

Technical Field

[0001] This utility model is designed for the metal processing industry, specifically relating to a cold isostatic pressing device. Background Technology

[0002] Cold isostatic pressing (COP) is a molding method that uses a liquid medium to apply uniform pressure to materials in all directions at room temperature. It is mainly used in powder metallurgy and ceramic manufacturing. COP can produce blanks with complex shapes and uniform density. However, for some heavy workpieces, the placement and removal of the elastic mold from the liquid medium requires auxiliary tooling. Traditionally, a basket is used to hold the workpiece or material powder wrapped in the elastic mold and then placed in the basket for pressurization in the isostatic liquid medium. This method is inefficient, wastes space, and has high production costs for heavy products.

[0003] For example, Chinese utility model patent CN220826750U provides a mold loading fixture for a cold isostatic press. This solution can be used in multiple stations, but it is not suitable for large-sized products. Chinese utility model patent CN221565508U provides an isostatic pressing hoisting fixture. This fixture can be used for large-sized products, but the workpiece placement is difficult, and it only has one station, resulting in significant space waste and high production costs. Utility Model Content

[0004] To address the problem that existing cold isostatic pressing fixtures cannot simultaneously accommodate the use of large-sized products, multiple workstations, and rapid placement and removal of workpieces, this utility model provides a cold isostatic pressing device with multiple workpiece workstations, suitable for both large and small workpieces, and enabling convenient and quick placement and removal of workpieces.

[0005] To achieve the above-mentioned technical effects, this utility model proposes: A cold isostatic pressing apparatus, comprising: The suspended platform includes several workpiece placement layers and a top plate. Each workpiece placement layer includes a partition. The partitions and the top plate are connected and fixed by screws and nuts. The top plate has lifting rings. A lifting platform is installed at the bottom of the suspended platform to adjust the horizontal height of the suspended platform; A loading platform, comprising a loading plate and a support, wherein the loading plate is provided with guide blocks; The transport vehicle, in conjunction with the guide blocks, transports the workpiece to the suspended basket.

[0006] The suspended platform has multiple workpiece placement layers, allowing for the simultaneous placement of both large and small workpieces, making full use of the cold isostatic pressure hydraulic chamber space. The platform is positioned above a lifting platform, which can raise or lower the platform to arbitrarily change its horizontal height. Any placement layer within the platform can be aligned with the loading platform, where a transport vehicle moves to move the workpiece to the corresponding placement layer.

[0007] The partition is circular, with a positioning hole at its center and several liquid holes on its surface.

[0008] The partition has three limiting blocks and a detachable block on one side surface. The limiting blocks are strip-shaped and enclose a workpiece inlet. The detachable block is strip-shaped and fits into the workpiece inlet to close it.

[0009] The screw includes three screws, and the positioning hole has a circular or rectangular shape.

[0010] The lifting platform includes a support plate and a folding lifting frame. The support plate is provided with a positioning block, the shape of which corresponds to the shape of the positioning hole. The folding lifting frame is driven by a hydraulic cylinder.

[0011] Both the support plate and the feeding plate are equipped with water baffles.

[0012] The feeding plate is provided with a mating interface, which is arc-shaped.

[0013] The guide rail includes two guide blocks, which are arranged parallel to each other on the surface of the feeding plate and extend to the interface.

[0014] The transport vehicle includes a main body and wheels disposed below the main body.

[0015] The transport vehicle is equipped with side wall guide wheels on its opposite side walls, with two guide wheels on each of the opposite side walls.

[0016] The beneficial effects of this utility model are: 1. The placement layer can be set according to different workpiece sizes, and can hold workpieces of various sizes; 2. The lifting platform, together with the loading platform and transport vehicle, makes it convenient and quick to place or remove workpieces to the corresponding placement layer; 3. Improve the utilization rate of the hydraulic chamber of cold isostatic pressing. Attached Figure Description

[0026] Example 1 Reference Appendix Figures 1 to 6 The cold isostatic pressing device in this embodiment includes a suspended basket 100, a lifting platform 200, a loading platform 300, and a transport vehicle 400. The suspended basket 100 includes two workpiece 500 placement layers 101 and a top plate 102. Each workpiece 500 placement layer 101 includes a partition 103. The two partitions 103 and the top plate 102 are connected and fixedly connected by screws 104 and nuts 105. The top plate 102 is provided with lifting rings 106 for hoisting. The lifting platform 200 is located at the bottom of the suspended basket 100 and is used to adjust the horizontal height of the suspended basket 100. The loading platform 300 includes a loading plate 302 and a support 301. The loading plate 302 is provided with guide rails 303. The transport vehicle 400 is mounted on the loading plate 302. The transport vehicle 400, in conjunction with the guide rails 303, transports the workpieces 500 to the placement layers 101 of the suspended basket 100.

[0027] In this embodiment, the partition 103 is circular in shape, with a positioning hole 109 at its center for positioning with the lifting platform 200. Several liquid holes 108 are formed on the surface of the partition 103. When the basket 100 is removed from the cold isostatic pressure hydraulic chamber, excess liquid is drained through the liquid holes 108.

[0028] In this embodiment, the surface of the partition 103 where the workpiece 500 is placed is provided with three limiting blocks 110 to limit the transport vehicle 400, confining the transport vehicle 400 containing the workpiece 500 to the partition 103. In this embodiment, the three limiting blocks 110 form a U-shape, and its opening serves as the workpiece inlet 112 for the transport vehicle 400 to enter. The workpiece inlet 112 needs to extend to the edge of the partition 103 for docking with the loading platform 300.

[0029] For details, please refer to the appendix. Figure 3 A removable stop block 111 is provided to close the U-shaped workpiece inlet 112, preventing the transport vehicle 400 carrying the large workpiece 500 from accidentally moving out. The length of the removable stop block 111 corresponds to the inner dimension of the workpiece inlet 112, allowing the removable stop block 111 to snap into the workpiece inlet 112. The limiting stop block 110 is welded to the partition plate 103. Two liquid holes 108 are provided on the outer side of the U-shape formed by the three limiting stops 110, and five liquid holes 108 are provided on each of the two opposite sides of the inner side of the U-shape.

[0030] It should be noted that the number of liquid holes 108 can be set multiple times, provided that the transport vehicle 400 can be stably placed on the partition 103, so as to achieve the effect of rapid liquid drainage after the basket 100 is taken out from the cold isostatic hydraulic chamber.

[0031] The spacing between the two side partitions 103 and the spacing between the partition 103 and the top plate 102 are set according to the height of the workpiece 500 to be placed, so that the workpiece 500 can be smoothly transported into the placement layer 101 by the transport vehicle 400.

[0032] In this embodiment, a screw hole 107 is provided on the outer side of the U-shaped bottom formed by the limiting block 110, and a screw hole 107 is provided on each of the two outer sides of the workpiece inlet 112. In this embodiment, the two partition plates 103 and the top plate 102 are connected in series by three screws 104 and fixedly connected by nuts 105.

[0033] In this embodiment, the lifting platform 200 includes a support plate 202 and a folding lifting frame 201. The support plate 202 is equipped with a positioning block 203, which is located in the middle of the support plate 202 and its shape corresponds to the shape of the positioning hole 109. The positioning hole 109 and the positioning plate cooperate to position the suspended platform 100. In this embodiment, both the positioning hole 109 and the positioning block 203 are circular. The folding lifting frame 201 is driven and controlled by a hydraulic cylinder, and has the function of providing support for the support plate 202 while changing the horizontal height of the support plate 202.

[0034] It should be noted that in this embodiment, the lifting platform 200 uses a folding lifting frame 201 to control the horizontal height of the support platform. In other embodiments of this embodiment, a hydraulic cylinder can be used to directly drive the support platform. The folding lifting frame 201 has a wide adjustable horizontal height range and a relatively simple structure.

[0035] In this embodiment, the support plate 202 includes a loading plate 302 and a bracket 301. The loading plate 302 is provided with a guide rail 303, which consists of two guide blocks 304. The bracket 301 supports the loading plate 302, which in turn supports the transport vehicle 400 and guides the transport vehicle 400 stably to the workpiece inlet 112 of the partition 103 via the guide blocks 304.

[0038] In this embodiment, side wall guide wheels 403 are provided on opposite sides of the transport vehicle 400 body, with two wheels provided on each side wall of the transport vehicle 400. The side wall guide wheels 403 enhance the guiding and limiting function of the guide rail 303 on the transport vehicle 400, and it is necessary to ensure that both sides of the side wall guide wheels 403 of the transport vehicle 400 abut against the guide block 304.

[0039] In this embodiment, both the support plate 202 of the lifting platform 200 and the loading plate 302 of the loading platform 300 are provided with water baffles 306 on their outer edges.

[0040] The steps for handling workpiece 500 in the cold isostatic pressing apparatus of this embodiment are as follows: Set both placement layers 101 of the suspended platform 100 as placement layers 101 for large-sized workpieces 500. Hoist the suspended platform 100 onto the lifting platform 200, ensuring that the positioning block 203 aligns with the positioning hole 109. (See attached document) Figure 7 Adjust the height of the lifting platform 200 so that the partition 103 is flush with the loading plate 302, ensuring that the partition 103 is aligned with the interface 305 and the workpiece inlet 112 is aligned with the guide rail 303. Position the transport cart 400 between the two guide blocks 304. Place the workpiece 500 on the transport cart 400, remove the detachable block 111, and transport the transport cart 400 along the guide rail 303 and workpiece inlet 112 to the bottom of the U-shaped limiting block 110. Reinstall the detachable block 111 at the workpiece inlet 112. Adjust the height of the lifting platform 200 and align the other partition 103 with the interface 305. Repeat the above steps to position the other workpiece 500. Hoist the cage into the cold isostatic pressing hydraulic chamber for processing. After processing, hoist the cage back onto the lifting platform 200, and the large and small workpieces 500 can be taken out sequentially.

[0044] In this embodiment, the surface of the partition 103 where the workpiece 500 is placed is provided with three limiting blocks 110 to limit the transport vehicle 400, confining the transport vehicle 400 containing the workpiece 500 to the partition 103. In this embodiment, the three limiting blocks 110 form a U-shape, and its opening serves as the workpiece inlet 112 for the transport vehicle 400 to enter. The workpiece inlet 112 needs to extend to the edge of the partition 103 for docking with the loading platform 300.

[0045] Specifically, the placement layer 101 for placing small workpieces 500 only requires three limiting blocks 110 forming a U-shape to meet the limiting requirements. For large workpieces 500, a removable block 111 is also needed to close the U-shaped workpiece inlet 112 to prevent the transport vehicle 400 carrying the large workpiece 500 from accidentally moving out. The length of the removable block 111 corresponds to the inner dimension of the workpiece inlet 112, allowing the removable block 111 to snap into the workpiece inlet 112. The limiting blocks 110 are welded to the partition plate 103. Two liquid holes 108 are provided on the outer side of the U-shape formed by the three limiting blocks 110, and five liquid holes 108 are provided on each of the two opposite sides of the inner side of the U-shape.

The support plate 202 is equipped with a positioning block 203, which is located in the middle of the support plate 202 and its shape corresponds to the shape of the positioning hole 109. The positioning hole 109 and the positioning plate cooperate to position the suspended platform 100. In this embodiment, both the positioning hole 109 and the positioning block 203 are circular. The folding lifting frame 201 is driven and controlled by a hydraulic cylinder, and has the function of providing support for the support plate 202 while changing the horizontal height of the support plate 202.

[0048] It should be noted that in this embodiment, the lifting platform 200 uses a folding lifting frame 201 to control the horizontal height of the support platform. In other embodiments of this embodiment, a hydraulic cylinder can be used to directly drive the support platform. The folding lifting frame 201 has a wide adjustable horizontal height range and a relatively simple structure.

[0049] In this embodiment, the support plate 202 includes a loading plate 302 and a bracket 301. The loading plate 302 is provided with a guide rail 303, which consists of two guide blocks 304. The bracket 301 supports the loading plate 302, which in turn supports the transport vehicle 400 and guides the transport vehicle 400 stably to the workpiece inlet 112 of the partition 103 via the guide blocks 304.
