[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] like Figures 1 to 8 One specific embodiment of the condensation bending processing device shown includes: multiple first cylindrical parts of different diameters, a circular base plate 1, two rotating parts, two support structures 2, and multiple handles 3. The condensation bend of this application is mounted on a pressure gauge, which can be used in the technical fields of nuclear power plants, thermal power plants, wind power generation, and hydropower generation.
[0035] like Figure 1 and Figure 3 As shown, multiple first cylindrical members with different diameters are arranged in ascending order of diameter. The flat surfaces of adjacent first cylindrical members are connected, specifically by welding. The central axes of the multiple first cylindrical members are located on the same horizontal line. The diameter of the first cylindrical member is the same as the diameter of the condensation bend to be processed. The circular base plate 1 is connected and disposed on the flat surface outside the first cylindrical member with the largest diameter. The diameter of the circular base plate 1 can be approximately 30 cm larger than the diameter of the first cylindrical member with the largest diameter. The center of the circular base plate 1 is located on the central axis of the first cylindrical member. Second cylindrical members 13 are provided near the edge of the flat surface of the first cylindrical members (excluding the smallest diameter members) and also near the edge of the circular base plate 1. All second cylindrical members 13 are oriented towards the flat surface outside the first cylindrical member with the smallest diameter. The central axes of all second cylindrical members 13 are located on the same straight line. The second cylindrical member 13 is a short column, which can be welded and connected to the first cylindrical member or the circular base plate 1. One end of each of the two rotating components is fixedly connected to the center of the first cylindrical component with the smallest diameter and the center of the circular base plate 1, respectively; the central axes of the two rotating components coincide with the central axis of the first cylindrical component, and the central axes of the two rotating components are parallel to the ground 9; the other ends of the two rotating components are rotatably connected to two supporting structures, respectively; such as Figure 2 and Figure 4 As shown, multiple handles 3 are evenly spaced around the outer periphery of the circular base plate 1.
[0036] Specifically, the first cylindrical component is a stainless steel tube with a closed open end; the circular base plate 1 is a steel plate.
[0037] Specifically, such as Figure 1 and Figure 3 As shown, there are three first cylindrical components, arranged in ascending order of diameter as a first stainless steel tube 4, a second stainless steel tube 5, and a third stainless steel tube 6. Circular plates are welded to the open ends of each stainless steel tube; these circular plates are steel plates. The distance between the outer arc surface of the second cylindrical component and the corresponding outer arc surface of the first cylindrical component is greater than the diameter of the tube 12 to be processed for condensation bending; alternatively, the distance between the outer arc surface of the second cylindrical component 13 and the corresponding outer arc surface of the first cylindrical component may be slightly greater than the diameter of the tube 12 to be processed for condensation bending.
[0038] Specifically, such as Figure 2 and Figure 4 As shown, there are four handles 3 that are evenly and symmetrically arranged.
[0039] Furthermore, a non-slip rubber sleeve is provided on the handle 3.
[0040] Specifically, the rotating component is a supporting circular tube 7.
[0041] Specifically, such as Figures 1 to 4 As shown, the support structure 2 includes: multiple support legs 8, a support plate 10, and an annular member 11. The bottom ends of the multiple support legs 8 are separated and stand on the ground 9; the support plate 10 is fixedly connected to the top surface of the multiple support legs 8. The annular member 11 is fixed to the top surface of the support plate 10, and the rotating member is located inside the annular member 11. The annular member 11 is a U-shaped member with its opening facing downwards, welded to the top surface of the support plate 10. The internal dimension of the annular member 11 is larger than the outer diameter of the rotating member, or the internal dimension of the annular member 11 may be slightly larger than the outer diameter of the rotating member; the number of support legs 8 is two.
[0042] The working process of the condensation bending processing device described in this application is briefly described as follows: Figure 3 As shown, one end of the pipe fitting 12 to be processed is wedged into the gap between the outer arc surface of the first cylindrical component and the outer arc surface of the second cylindrical component 13, and the other end of the pipe fitting 12 is pulled downward along the outer arc surface of the first cylindrical component, as shown. Figure 3 As shown, the arrow indicates the direction in which the pipe fitting 12 is pulled downwards. Figure 4 As shown, the arrow on the left indicates the direction to pull the pipe fitting 12, and then follow... Figure 4 Rotate handle 3 in the direction indicated by the arrow on the right. When the rotation angle of handle 3 is 180 degrees, pipe fitting 12 forms a U-shaped bend; when the rotation angle of handle 3 is 360 degrees, pipe fitting 12 forms a circular bend; when the rotation angle of handle 3 is 480 degrees, pipe fitting 12 forms a condensation bend. The above rotation angles of handle 3 are empirical data and are for reference only. In actual operation, adjustments can be made according to the material of pipe fitting 12 and the type of finished product. When the rotation of handle 3 is complete, the following shape is formed: Figure 5The semi-finished condensation bend shown. Remove the semi-finished condensation bend and locate the two intersection points where the condensation bend of fitting 12 intersects with the two ends of fitting 12. The two intersection points are as follows: Figure 6 The circles at both ends of the vertical line are shown. One intersection point is positioned within the gap between the outer arc surface of the first cylindrical member and the outer arc surface of the second cylindrical member 13. The handle 3 is rotated in the opposite direction, causing the extended end of the tube 12 to bend in the opposite direction. Similarly, the other intersection point is positioned within the gap between the outer arc surface of the first cylindrical member and the outer arc surface of the second cylindrical member 13. The handle 3 is rotated in the opposite direction, causing the other extended end of the tube 12 to bend in the opposite direction, forming a shape as shown. Figure 7 The state shown. The final condensation bend finished product is as follows. Figure 8 As shown.
[0043] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
