Abstract
Description
Technical Field
[0001] The utility model relates to a half-type flange, in particular to a half-type flange which can be processed in half by adopting three paths, each linear cutting path is on the same plane, the cutting path becomes single, the processing efficiency is improved, and the processing-friendly half-type flange is easy to process. Background Art
[0002] The split-half flange connection is a common pipe connection method. Its main feature is that the flange is divided into two halves, making it easier to maintain and replace, reducing installation time and costs and improving work efficiency. The split-half flange connection method is suitable for connecting pipes of various specifications and is versatile, suitable for installation in various pressure and temperature conditions.
[0003] Split flange connections are widely used in piping systems in the fields of petroleum, chemical industry, steel metallurgy, pharmaceuticals, etc. Split flanges are widely used in engineering fields such as large chemical companies, oil and gas companies, and power plants.
[0004] The existing half-flange structure mainly includes: an upper half flange (3), a lower half flange (1), a first threaded hole (2), a second threaded hole (5), and a third threaded hole (4). The half-flange is a whole flange that is divided into two halves by wire cutting. In actual application, the upper half flange (3) and the lower half flange (1) are assembled into one piece by the first threaded hole (2), the second threaded hole (5) and bolts, and are used in conjunction with pipelines and bolt connections.
[0005] A split flange is made by cutting a single flange into two halves using wire cutting. The efficiency of wire cutting depends primarily on the geometry of the part and the complexity of the wire cutting path. Because the geometry of a split flange is relatively regular, the only factor affecting wire cutting efficiency is the cutting path.
[0006] from Figure 1 It can be seen that the existing half-type flange wire cutting paths are the first wire cutting path (6), the second wire cutting path (7), the third wire cutting path (8), the fourth wire cutting path (9), the fifth wire cutting path (10), and the sixth wire cutting path (11). Although the wire cutting paths of the first wire cutting path (6), the second wire cutting path (7), the third wire cutting path (8), the fourth wire cutting path (9), the fifth wire cutting path (10), and the sixth wire cutting path (11) are the same, since each wire cutting path is not on the same plane, the same wire cutting path needs to be cut twice, which greatly reduces the processing efficiency. Especially in mass production, the processing cost increases significantly. Utility Model Content

[0024] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to illustrate the technical solutions of the present invention in detail.
[0025] Figure 3 This is the main view of the structural diagram of the half-type flange proposed in the utility model. Figure 4 This is a three-dimensional diagram of the structural schematic diagram of the half-type flange proposed in the present invention. Figure 5 for Figure 4 A partial enlarged view of Figure 3-5As shown: The utility model proposes a half-type flange that is easy to process, which includes: an upper flange 3, a lower flange 1, a first threaded hole 2, a second threaded hole 5, and a third threaded hole 4; the upper flange 3 and the lower flange 1 are an integral flange that are divided into two halves through wire cutting, and the two joints of the upper flange 3 and the lower flange 1 are provided with steps that cooperate with each other.
[0026] The first threaded hole 2 and the second threaded hole 5 are located at two joints. The third threaded hole 4 is located on the circumference surrounded by the upper flange 3 and the lower flange 1, and does not include the threaded holes at the joint. There are three wire cutting paths between the upper flange 3 and the lower flange 1, and each wire cutting path of the upper flange 3 and the lower flange 1 is on the same plane.
[0027] The three wire cutting paths are: the first wire cutting path 6, the second wire cutting path 7, and the third wire cutting path 8. The first wire cutting path 6 and the third wire cutting path 8 are parallel to the axial direction of the upper flange 3, and the second wire cutting path 7 is perpendicular to the axial direction of the upper flange 3.
[0028] The cutting thickness of the first and third wire cutting paths 6 and 8 is equal, and the second wire cutting path 7 penetrates the integral flange. The second wire cutting path 7 is perpendicular to the first and third wire cutting paths 6 and 8 .
[0029] The cutting thicknesses of the first and third wire cutting paths 6 and 8 are equal, and the second wire cutting path 7 penetrates the integral flange.
[0030] The second wire cutting path 7 is perpendicular to the first wire cutting path 6 , and the second wire cutting path 7 is perpendicular to the third wire cutting path 8 .
[0031] The first threaded hole 2 and the second threaded hole 5 are located in the middle of the two joints. The upper flange 3 and the lower flange 1 are both provided with the first threaded hole 2 and the second threaded hole 5. After the upper flange 3 and the lower flange 1 are combined, the first threaded hole 2 and the second threaded hole 5 are combined into a through hole.
[0032] The diameters of the first threaded hole 2, the second threaded hole 5, and the third threaded hole 4 are all the same. The diameters of the first threaded hole 2, the second threaded hole 5, and the third threaded hole 4 are 1 / 4-1 / 2 of the overall flange width. In specific implementation examples, the above values can also be other parameters.
[0033] like Figure 2As shown in the figure, the wire cutting path has been optimized based on the original split-half flange. When wire cutting a split-half flange, the flange can be split into two halves using three paths: the first wire cutting path 6, the second wire cutting path 7, and the third wire cutting path 8. After optimizing the wire cutting path, each wire cutting path is aligned on the same plane, resulting in a single cutting path and improved processing efficiency.
[0034] The new half-flange structure optimizes the wire cutting processing path based on the original structure, so that each wire cutting path is on the same plane. The same wire cutting path only needs one cutting to complete the processing of the part, greatly improving the processing efficiency.
[0035] The specially designed half-flange structure of the utility model effectively avoids the problem of low processing efficiency during the production and processing process. Compared with the existing product structure, the structure of the utility model is more reasonable and reliable. Especially in large-scale production, it can greatly reduce the production and processing costs, thereby achieving the purpose of reducing costs and increasing efficiency.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
