Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for static presses, specifically a production material basket for an ultra-high pressure isostatic press. Background Technology

[0002] Ultra-high pressure isostatic presses are widely used in the molding and processing of materials such as ceramics and metal powders. They achieve densification of the workpiece by applying uniform ultra-high pressure and high temperature to a closed cavity.

[0003] As a core component in ultra-high pressure isostatic presses that carries the workpieces to be processed, the structural design of the production material basket directly affects the forming quality of the workpieces, processing efficiency, and the operational stability of the equipment. For example, the utility model patent with announcement number CN222538360U discloses an isostatic press (hereinafter referred to as the prior art), which includes a cylinder, a cover, a pressurizing mechanism, a material rack, and a drying mechanism.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-3 This embodiment discloses a material frame for placing workpieces and materials, including a bottom plate 101, a side plate 102 and a top plate 103, wherein the top plate 103 and the bottom plate 101 are connected by the side plate 102.

[0034] The side plate 102 is provided with several mounting slots from top to bottom. A partition 104 is detachably installed in the mounting slot. A limiting mechanism 105 and a baffle assembly 106 are installed on both the partition 104 and the bottom plate 101. The partition 104 and the bottom plate 101 are detachably connected to the limiting mechanism 105.

[0035] The baffle assembly 106 is symmetrically installed at the front and rear ends of the partition 104 and the bottom plate 101. The bottom end of the bottom plate 101 and the partition 104 is provided with a first guide groove 107, and the top plate 103 is provided with a pressure relief groove 108.

[0036] In this embodiment, the upper and lower ends of the side plate 102 are respectively threaded to the top plate 103 and the bottom plate 101 by existing bolts to form the main structure. When the workpiece needs to be processed, the workpiece to be processed is placed on the bottom plate 101 and the partition plate 104. A placement area is formed between the limiting mechanism 105. The workpiece is placed in the placement area. The limiting mechanism 105 is used to limit the workpiece laterally to prevent lateral displacement. After placement, the baffle assembly 106 is rotated inward to block the workpiece longitudinally. When the pressure medium and heat transfer medium enter from the first guide groove 107 at the bottom of the basket, the medium is evenly distributed in the basket to ensure that all parts of the workpiece are subjected to uniform pressure and temperature. After the workpiece is processed, the ultra-high pressure isostatic press begins to depressurize. The high pressure medium in the basket is discharged through the pressure relief groove 108 on the top plate 103 to ensure that the workpiece is depressurized smoothly. After depressurization, the baffle assembly 106 is rotated outward to facilitate the removal of the workpiece from the placement area. By making the partition 104 detachably connected to the mounting groove on the side plate 102, the number and spacing of the partition 104 layers can be flexibly adjusted to accommodate workpieces of different sizes and quantities, thereby improving space utilization and production efficiency.

[0037] In some embodiments, the first guide channel 107 includes a central hole 109 and diversion holes 110. The central hole 109 is located at the center of the partition 104 and the bottom plate 101. There are a plurality of diversion holes 110, which are equally spaced around the circumference of the central hole 109. In this embodiment, the central hole 109 serves as the main inlet for the medium and is located at the geometric center of the partition 104 and the bottom plate 101. This allows the high-pressure medium to be injected quickly into the placement area, avoiding filling delays caused by excessively long paths when the medium flows from the edge to the center. By setting the diversion holes 110, the medium diffusion path can be shortened, increasing the medium filling speed. Furthermore, by setting the diversion holes 110, multi-point liquid and gas inlet can be achieved, diverting part of the medium flow rate and preventing the medium entering the central hole 109 from impacting the workpiece or causing turbulence due to medium disturbance.

[0038] In some embodiments, the pressure relief groove 108 includes a main pressure relief hole 111 and buffer holes 112. The main pressure relief hole 111 is located at the center of the top plate 103, and there are several buffer holes 112, which are evenly spaced along the circumference of the main pressure relief hole 111. In this embodiment, by setting the main pressure relief hole 111, the total pressure relief time can be shortened, and production efficiency can be improved. By setting several buffer holes 112 that are evenly spaced along the circumference of the main pressure relief hole 111, the flow rate of the medium can be controlled by multi-point diversion, the pressure relief rate of the main pressure relief hole 111 can be slowed down, and the pressure fluctuation during the pressure relief process can be balanced. This avoids the medium from converging from all sides to the center of the main pressure relief hole when a single main pressure relief hole 111 is depressurized, forming a vortex zone below the main pressure relief hole 111, which would cause the local impact force generated by the vortex to act on the workpiece and cause damage to the workpiece.

[0039] In some embodiments, a second guide groove 113 is provided on the side plate 102. In this embodiment, when the medium permeates upward from the bottom plate 101 and the partition 104, an axial pressure difference with a higher bottom and lower top is formed in the material basket due to the dynamic resistance of the material. At the same time, the material near the center of the bottom plate 101 and the partition 104 is directly affected by the medium, and the pressure is transmitted faster, while the material near the side plate 102 is more prone to radial pressure difference due to the slower medium permeation. The radial guiding effect of the second guide groove 113 allows the high-pressure medium to be replenished from the side plate 102 towards the center, establishing multiple pressure input channels in the radial direction. This avoids material near the side plate 102 from having uneven medium distribution, which could lead to differences in material forming quality.

[0040] In some embodiments, the limiting mechanism 105 includes a limiting frame 114 and a connecting member 115. The limiting frame 114 is detachably connected to the base plate 101 and the partition plate 104 via the connecting member 115. In this embodiment, the limiting frame 114 is detachably connected to the base plate 101 and the partition plate 104 via the connecting member 115. By adjusting the number and spacing of the limiting frames 114, the distance between adjacent limiting frames 114 can quickly adapt to the lateral limiting requirements of different numbers, sizes, and even irregularly shaped workpieces, significantly improving applicability, reducing production costs, and increasing production efficiency.

[0041] In some embodiments, the connector 115 is rotatably connected to the open end of the limiting frame 114, and the base plate 101 and the partition plate 104 are provided with threaded holes, and the limiting frame 114 is threadedly connected to the threaded holes through the connector 115. In this embodiment, the limiting frame 114 can be quickly and easily installed or removed simply by rotating the connector 115.

[0042] In some embodiments, the baffle assembly 106 includes a baffle body 116, a limiting mechanism 105, and a rotating shaft. The base plate 101 and the partition plate 104 are rotatably connected to the baffle body 116 via the rotating shaft. The limiting mechanism 105 includes a movable pin 118 and a spring 119. The movable pin 118 is slidably connected to the baffle body 116, and the baffle body 116 is connected to the movable pin 118 via the spring 119. The base plate 101 and the partition plate 104 are provided with fixing holes 117 for cooperating with the movable pin 118. In this embodiment, the rotating shaft is fixedly connected to the rotating end of the baffle body 116. The rotating shaft is rotatably connected to the base plate 101 and the partition plate 104 through a conventional bearing mechanism in the prior art. Before placing a workpiece, simply pull the moving pin 118 upward to move it, so that the spring 119 is compressed. After the moving pin 118 moves to the outside of the fixing hole 117, the baffle body 116 can be rotated outward by the rotating shaft, making it easy to pick up and place the workpiece. When high-pressure processing is required, the baffle body 116 is rotated inward, so that the moving pin 118 moves to the position corresponding to the fixing hole 117. Under the action of the spring 119, the moving pin 118 can move into the fixing hole 117, so that the baffle body 116 can once again longitudinally block the workpiece in the limiting area.

[0043] In some embodiments, the partition 104 is slidably connected to the mounting groove, and a locking element is threaded onto the mounting groove. In this embodiment, by making the partition 104 slidably connected to the mounting groove, the number and position of the partitions 104 can be freely adjusted according to the workpiece size, meeting the placement space requirements of different workpieces.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
