[0012] Compared with the prior art, the advantages of the present utility model are as follows: it can fix the tube sheet and prevent the tube sheet from shaking during the welding of the tube sheet and the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings described below are only some embodiments recorded in the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.
[0014] Figure 1 The cross-sectional view of the tube sheet clamping tooling in the embodiment of the present utility model is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The following will combine the drawings in the embodiments of the present utility model to describe the technical solutions in the embodiments of the present utility model in detail. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0016] Combined with Figure 1 As shown, the tube sheet clamping tooling is used to clamp the tube sheet (not shown in the figure). The tube sheet includes a circular plate body and tube holes uniformly distributed on the surface of the circular plate body. It includes an annular plate body 100. A cylindrical cavity 101 is coaxially formed inside the annular plate body 100. The inner diameter of the cylindrical cavity 101 is smaller than the outer diameter of the tube sheet. An annular cavity 102 is concavely formed on the inner wall of the cylindrical cavity 101. The outer diameter of the annular cavity 102 is slightly larger than the outer diameter of the tube sheet. The thickness of the annular cavity 102 is slightly larger than the thickness of the tube sheet. A plurality of mounting holes 103 are formed along the circumferential direction on the outer side of the annular plate body 100.
[0017] During use, the annular plate body 100 is divided into two pieces along the diameter. After the outer periphery of the tube sheet is clamped into the annular cavity 102, the tube sheet is fixed, and the annular plate body 100 is fixedly installed through the mounting holes 103.
[0018] In this embodiment, the tube sheet can be fixed to prevent the tube sheet from shaking during the welding of the tube sheet and the pipeline.
[0019] Further, the outer diameter of the annular cavity 102 is 1.5 - 2.5 mm larger than the outer diameter of the tube sheet. The thickness of the annular cavity 102 is 0.4 - 0.6 mm larger than the thickness of the tube sheet. The thickness of the annular plate body 100 is 36 - 42 mm. The width of the annular cavity 102 is 40 - 50 mm. The distance from the annular cavity 102 to the proximal end face of the annular plate body 100 is 3 - 6 mm.
[0020] In this embodiment, since the outer diameter of the tube sheet is greater than 2 m, in order to ensure the accuracy, the above parameters are used to manufacture this clamping tooling to ensure that the tube sheet is not damaged and is stably fixed.
[0021] During the specific implementation, since the diameter of the tube sheet clamping tooling is relatively large, warping will occur when it is cut in half after processing, and the tooling plate needs to be solution-treated. This tooling can be formed by splicing 4 plates. First, the 4 plates are welded into shape. Then solution treatment is carried out. After the heat treatment is completed, turning is carried out to process each dimension, and after the processing is completed, it is cut into 2 pieces.
[0022] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.
[0023] The above are only specific implementation manners of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
