Description

Technical Field

[0001] This utility model relates to the field of bending auxiliary devices, and in particular to a bending auxiliary device for a circular water-stop copper sheet. Background Technology

[0002] After the excavation of the diversion (water intake) tunnel for the reservoir project is completed, shotcrete is used for support. The tunnel radius after shotcrete support is generally 2.15m. Reinforced concrete lining is then installed, with a lining thickness of approximately 40cm. The lining radius after lining is 1.75m, classifying it as a small-section tunnel construction. Multiple structural joints are constructed within the tunnel. Water-stopping copper sheets are required for these joints. The copper water-stopping type is W-shaped. Because the tunnel cross-section is circular, the required copper water-stopping sheets must be machined into a circular shape before use.

[0003] In the existing technology, during the preparation of circular waterstop copper sheets, the copper waterstop nose and flange are formed in one step in the factory using a punch press, and the entire waterstop is straight. However, if it is to bend into an arc shape, a specially customized mold is required for secondary stamping, which increases the cost. In addition, the transportation of circular waterstop copper sheets becomes more difficult and the transportation cost increases.

[0004] Therefore, it is necessary to provide a new auxiliary device for bending circular water-stop copper sheets to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the circular water-stop copper sheet bending auxiliary device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the structure from another angle is shown; Figure 3 for Figure 1 A partial structural diagram of the structure shown; Figure 4 for Figure 3 A partial structural diagram of the structure shown.

[0019] In the specific implementation process, such as Figures 1-4 As shown, the device includes a support device on which multiple concentric inner rings 1 are mounted. An unclosed outer ring 2 is positioned outside each inner ring 1. The outer ring 2 is welded to the inner rings 1 via multiple connecting steel bars 3. Multiple positioning posts 4 are welded onto the outer ring 2. Each positioning post 4 is fitted with a connecting ring 5. A positioning ring 6 is welded to all connecting rings 5. The positioning ring 6 is located inside the positioning posts 4 and can slide and lock relative to the positioning posts 4. The positioning ring 6 has an unclosed structure, with one end of the positioning ring 6... A fixed moving device is provided, which has two movable ends that can move in opposite directions. Each movable end is equipped with a pressing device. When processing the water-stop copper sheet, the height of the positioning ring 6 is first adjusted according to the size of the water-stop copper sheet. Then, one end of the water-stop copper sheet is fixed on the two pressing devices. The water-stop copper sheet is lifted and the "nose" is aligned with the positioning ring 6. It moves around the inner side of multiple positioning posts 4, and the entire water-stop copper sheet is bent into a ring shape. After completion, it can be taken out for lining. The bending process of the water-stop copper sheet is quick and labor-saving, and it is easy to process and shape. The moving device includes a moving column 7, a threaded rod 8, and two transmission plates 9. The moving column 7 has a receiving groove. The threaded rod 8 is rotatably connected to the moving column 7. The threaded rod 8 has a left thread and a right thread at both ends. The left thread and the right thread are threadedly connected to the transmission plates 9. The transmission plates 9 move through the insertion hole 15 opened in the inner wall of the receiving groove. The size of the transmission plates 9 is adapted to the size of the insertion hole 15. For ease of operation, a handle can be fixed to one end of the threaded rod 8 that extends out of the receiving groove. When in use, the distance between the two pressing devices is adjusted according to the length of the plates on both sides of the "nose" of the water-stop copper sheet. Turning the handle drives the threaded rod 8 to rotate. Since the two transmission plates 9 are limited by the insertion hole 15, the two transmission plates 9 move in opposite directions, thereby driving the pressing devices on them to move, thus realizing the adjustment of the distance between the two pressing devices. The pressing device includes a first upright plate 10, a second upright plate 11, a pressing plate 12, and a threaded frame 13. The first upright plate 10 and the second upright plate 11 are both fixed on the transmission plate 9. The threaded frame 13 is threadedly connected to the first upright plate 10. One end of the threaded frame 13 is rotatably connected to the pressing plate 12. One end of the pressing plate 12 is slidably disposed in the guide groove 14 opened in the transmission plate 9. The plate body on the "nose" side of the water-stop copper sheet is placed between the second upright plate 11 and the pressing plate 12. The threaded frame 13 is rotated. Since one end of the pressing plate 12 is slidably disposed in the guide groove 14 opened in the transmission plate 9, the pressing plate 12 moves towards the second upright plate 11 when the threaded frame 13 rotates. The pressing plate 12 and the second upright plate 11 achieve pressing and clamping of the plate body, so that the end of the water-stop copper sheet is not easily displaced during the subsequent bending process. At least three of the multiple positioning pins 4 have threaded sections, and the threaded sections are provided with limiting members for limiting the connecting ring 5. The three positioning pins 4 with threaded sections are respectively located at the two edges and the middle of the multiple positioning pins 4. The limiting members include a first nut 16 and a second nut 17, which are both threadedly connected to the threaded sections. The connecting ring 5 is located between the first nut 16 and the second nut 17. When adjusting the height of the positioning ring 6, the positioning ring 6 is moved, and the positioning ring 6 drives the multiple connecting rings 5 ​​to move on the multiple positioning pins 4. After moving to the appropriate position, the first nut 16 and the second nut 17 are rotated so that the first nut 16 is supported at the bottom of the connecting ring 5 and the second nut 17 is attached to the top of the connecting ring 5, thereby limiting the connecting ring 5. Thus, the position adjustment of the positioning ring 6 can be completed. The support device includes four vertical steel pipes 18 and four horizontal steel bars 19. The four vertical steel bars are arranged in a matrix. A horizontal steel bar 19 is welded on two adjacent vertical steel pipes 18. The stability of the entire device is effectively improved through this support device structure. The vertical steel pipes 18 have a specification of Φ48*3.5. The inner ring 1 is provided in three parts, and the radii of the three inner rings 1 are 0.5m, 1m and 1.5m respectively from small to large. All three inner rings 1 are made of steel bars with a diameter of 20mm. The outer ring 2 has a radius of 1.95m. There are 35 connecting steel bars 3. The positioning post 4 has a length of 15cm. It should be noted that in this application, the copper waterstop processing is carried out in two steps. The first step is to process the waterstop into a W shape using a punch press in the factory, and then process it into a straight line in sections. The second step is to transport it to the construction site and then use this device to make it into an arc shape.
