Description

Technical Field

[0001] The utility model belongs to the technical field of hot isostatic pressing, and specifically relates to a single-layer cylinder cooling device for a hot isostatic pressing device used in a closed container to apply high temperature and high pressure to the interior to complete the sintering or densification process of the internal product. Background Art

[0002] Hot isostatic pressing (HIP) is a process that applies high temperature and high pressure within a sealed container to sinter or densify the product. Therefore, it has strong production and processing capabilities in areas such as high-temperature alloys, titanium alloys, cemented carbide, engineering ceramics, and composite materials. Over the past decade, increasing operating pressures have placed higher demands on container materials and design. Prestressed wire winding barrels, due to their high structural fatigue strength, light weight, and ease of manufacturing, have gradually gained application in HIP machines. Low-cost manufacturing has steadily increased the profit margins of HIP containers. However, the HIP double-layer structure is cumbersome to manufacture, with poor cooling, inconvenient installation, and difficult handling, making it difficult to meet practical needs. Utility Model Content

[0003] The purpose of the utility model is to solve the problem of complicated installation and poor cooling effect of the hot isostatic pressing double-layer structure and to provide a single-layer sleeve cooling device for hot isostatic pressing device which adopts a single-layer sleeve cooling method, is easy to install, easy to load and unload, and is economical and practical.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a single-layer cylinder cooling device for a hot isostatic pressing device, comprising upper and lower semicircular beams, columns arranged between the upper and lower semicircular beams, and a single cylinder fixed between the upper and lower semicircular beams and the columns by upper and lower pads, an upper plug and a lower plug are respectively plugged in the upper and lower ports of the single cylinder, the upper plug and the lower plug are fixed by the upper and lower semicircular beams through the upper and lower pads arranged thereon, an external prestressed steel wire is wound between the upper and lower semicircular beams and the columns, and a single-cylinder prestressed steel wire is wound around the outside of the single cylinder, upper and lower water-through flanges are installed on the two ends of the single cylinder by screws, the single-cylinder prestressed steel wire is located between the upper and lower water-through flanges, and a semicircular plate is also provided on the single cylinder between the upper and lower water-through flanges; a single-cylinder annular water trough and a single-cylinder spiral water channel connected to the single-cylinder annular water trough are opened on the outer wall of the single cylinder, and the single-cylinder annular water trough is connected to the external cooling water pipeline through the water channel opened in the upper and lower water-through flanges.

[0005] The single-cylinder spiral water channel refers to a 45° spiral water channel opened on the outer circular wall of the single cylinder.

[0006] The utility model has the following positive effects: This device has a single-layer cylinder structure. The outer wall is prestressed by winding steel wire to prevent the inner cylinder from failing or losing stability during operation. The winding tension is controlled, the stress on the inner wall is uniform, and the total weight of the steel wire winding is reduced. A cooling water channel is designed on the outer wall of the single cylinder of this device for the purpose of cooling the cylinder. The water channel is annular water grooves machined at both ends of the single cylinder, and a spiral water channel is evenly distributed at 45° on the outer circumference of the cylinder. The annular grooves are connected to the evenly distributed spiral water channel. Cooling water is introduced through a water flange installed at the upper end of the single cylinder. The cooling water enters the annular groove on the outer circumference of the single cylinder. After the annular groove is filled with water, it enters the evenly distributed spiral water channel on the outer circumference of the single cylinder. The cooling effect is significant and thermal deformation is not easily caused. The steel wire wrapped around the outer wall of the single cylinder of this device is made of 65Mn, which has a high yield point and strength. Semi-circular plates are installed on the outer side of the steel wire of the single cylinder to support the upper and lower parts of the single cylinder. The semi-circular plates are made of stainless steel S30408, which is not corroded by cooling water and can effectively isolate the cooling water. Therefore, the utility model has the advantages of low material and processing costs, convenient operation, time and labor saving, and easy promotion. BRIEF DESCRIPTION OF THE DRAWINGS
