[0027] Please refer to Figure 1-2The utility model provides a technical solution: a one-time forming and bending machine for a hanging bar, comprising a processing table 1, a protective cover 2 is arranged on the top outer surface of the processing table 1, a mounting plate 3 is fixedly connected to the top outer surface of the processing table 1 inside the protective cover 2, a first driving device 4 is installed on the outer surface of the mounting plate 3, a mounting end of the first driving device 4 is fixedly connected to the left outer surface of the mounting plate 3, an output end of the first driving device 4 movably penetrates the outer surface of the mounting plate 3, a first mounting seat 5 is fixedly connected to the output end of the first driving device 4, a forming disk 6 is installed on the outer surface of the first mounting seat 5, a second mounting seat 7 is fixedly connected to the left end of the top outer surface of the processing table 1, and a first forming mold 8 is installed on the outer surface of the second mounting seat 7, such as Figure 3 As shown, two mounting frames 9 are fixedly connected to the right side of the second mounting seat 7, and second driving devices 10 are installed on the outer surfaces of the two mounting frames 9. The mounting ends of the two second driving devices 10 are respectively installed on the outer surfaces of the two mounting frames 9 away from the molding disk 6, and the output ends of the two second driving devices 10 are fixedly connected to the third mounting seat 11, and the outer surfaces of the two third mounting seats 11 are installed with second molding molds 12. The outer surface of the first molding mold 8 is provided with a molding semicircular groove 21, and the two second molding molds 12 are provided with molding grooves.

[0028] In the present embodiment, when it is necessary to process and shape the lifting ring reinforcement, a customized mold is used for the reinforcement to be processed, and the vertical steel bar is placed on the protective cover 2, and the forming disk 6 is facing one end of the first forming mold 8, and the first driving device 4 is turned on. The first driving device 4 drives the forming disk 6 to move, so that the forming disk 6 moves toward one end close to the first forming mold 8, so that one end of the forming disk 6 abuts against one end of the forming semicircular groove 21, and then the second driving device 10 is turned on, and the second driving device 10 drives the second forming mold 12, so that the two second forming molds 12 are close to each other, so that the two second forming molds 12 move to a position abutting against the forming disk 6, and one side of the steel bar is processed into an arc shape by the first forming mold 8, and the two ends of the steel bar are pressed together by the second forming mold 12, and the lifting ring reinforcement is processed and shaped. The processed lifting ring reinforcement is as shown in FIG. Figure 6 As shown in the figure, a welding gun is then used to weld the two end connections of the processed hanger bar. The entire process can be completed by a single worker, so that the steel bar is hydraulically extruded into a one-time molding, which significantly improves the processing efficiency and saves labor costs. At the same time, the size specifications of the processed hanger bar are more standardized and unified, which is convenient for actual construction on site.

[0029] Optionally, the driving device is a hydraulic cylinder.

[0030] like Figure 4-5As shown, a connecting groove 13 is opened inside the processing table 1, and the front and rear inner walls and the rear inner wall of the connecting groove 13 are rotatably connected with threaded rods 14, the outer surfaces of the three threaded rods 14 are threadedly connected with threaded blocks 18, and the top outer surfaces of the three threaded blocks 18 are installed with electric push rods 19, and the output end of the electric push rod 19 is fixedly connected with a push rod 20.

[0031] In this embodiment, when the threaded rod 14 rotates, it drives the threaded block 18 to move, adjusts the positions of the multiple push rods 20, and thus adjusts the outer diameters of the three push rods 20 to make them suitable for use with forming disks 6 of different sizes. The push rod 20 is driven by the electric push rod 19 so that the push rod 20 pushes out the formed hanging rod to facilitate unloading.

[0032] like Figure 5 As shown, a motor 15 is installed on the top inner wall of the connecting groove 13 , and a driving bevel gear 16 is fixedly sleeved on the output end of the motor 15 , and driven bevel gears 17 are fixedly sleeved on the outer surfaces of the threaded rods 14 , and the three driven bevel gears 17 are movably meshed with the driving bevel gear 16 .

[0033] In this embodiment, when the motor 15 is working, it drives the active bevel gear 16 to rotate, and the active bevel gear 16 drives the driven bevel gear 17 to rotate, so that the three threaded rods 14 rotate.

[0034] like Figure 5 As shown, the top outer surface of the processing table 1 and the outer surface of the protective cover 2 are both provided with three slide grooves corresponding to the top rod 20 .

[0035] In this embodiment, the width of the slide groove is greater than the diameter of the output rod of the electric push rod 19 and the push rod 20, and a channel is provided for the output end of the electric push rod 19 and the push rod 20 through the slide groove.

[0036] like Figure 5 As shown, the front and rear inner walls and the left inner wall of the slide groove are fixedly connected with slide rods, and the three threaded blocks 18 are movably sleeved on the outer surfaces of the three slide rods respectively.

[0037] In this embodiment, when the threaded rod 14 drives the threaded block 18 to move, the threaded block 18 slides on the outer surface of the slide rod, thereby preventing the threaded block 18 from rotating along with the rotation of the threaded rod 14 .

[0038] When the forming semicircular groove 21 is connected with two forming grooves, it is located on the edge line of the circular groove with the same center.

[0039] In this embodiment, a hanger bar with a better shape can be produced.

[0040] The forming plate 6 and the second mounting seat 7, the second mounting seat 7 and the first forming mold 8, and the third mounting seat 11 and the second forming mold 12 are all fixed by bolts.

[0041] In this embodiment, the above technical solution is adopted to disassemble the forming disc 6 and each forming mold by removing the bolts, so as to facilitate the replacement of the forming disc 6 and each forming mold.

[0042] After the processing of the suspension bar is completed, the second drive device 10 is retracted first, and then the first drive device 4 is retracted. The first drive device 4 drives the processed suspension bar to move. At this time, the ring suspension bar is wrapped around the forming disk 6. After the first drive device 4 is fully retracted, the electric push rod 19 is turned on. The electric push rod 19 drives the push rod 20 to move upward. When the push rod 20 contacts the bottom of the annular end of the suspension bar, as the electric push rod 19 moves upward, the processed ring suspension bar is separated from the forming disk 6, which is convenient for unloading, further improving the processing efficiency. According to the different sizes of the forming disk 6, the position of the three push rods 20 can be adjusted. At this time, the motor 15 works, and the motor 15 drives the active bevel gear 16 to rotate. The active bevel gear 16 drives the driven bevel gear 17 to rotate the threaded rod 14. The rotation of the threaded rod 14 drives the threaded block 18 to move, so that the push rod 20 moves, thereby adjusting the outer diameter of the three push rods 20 to make it suitable for the use of forming disks 6 of different sizes. The prepared suspension bar is as follows Figure 6 shown.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
