[0024] Please see Figure 1-4 This utility model provides an embodiment of a bending device for a crossarm of an electric railway accessory, comprising a base 1, a support frame 3 fixedly connected to the left side of the top of the base 1, a reserved groove 4 opened at the bottom of the support frame 3, a workbench 2 provided at the top of the base 1, a pressure plate 5 provided at the top of the workbench 2, a limit frame 23 provided at the right side of the top of the base 1, a first hydraulic cylinder 24 on the left side of the limit frame 23, a connecting block 28 installed on the left side of the first hydraulic cylinder 24, a second hydraulic cylinder 26 installed at the top of the connecting block 28, an mounting plate 17 provided at the top of the second hydraulic cylinder 26, a first connecting frame 15 on the right side of the pressure plate 5, guide rollers 14 respectively provided between the first connecting frame 15 and the second connecting frame 19, a scale 18 machined on the top of the front end of the workbench 2, a limit groove 25 fixedly connected to the bottom of the limit frame 23, rolling grooves 27 opened on both sides of the connecting block 28, and ball bearings 29 provided inside the rolling grooves 27.

[0025] The bottom end of the connecting block 28 is set inside the limiting slide groove 25. The bottom end of the connecting block 28 slides left and right inside the limiting slide groove 25. The guide roller 14 is provided with two sets, and the ball 29 rolls inside the rolling groove 27.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when it is necessary to adjust the distance between the guide rollers 14, the first hydraulic cylinder 24 is activated. Since the second hydraulic cylinder 26 is installed at the top of the connecting block 28, the first hydraulic cylinder 24 can drive the guide rollers 14 between the second connecting frames 19 to move left and right through the connecting block 28. Adjusting the distance between the guide rollers 14 can make it easy to bend the crossbeam into different angles. After adjustment, the second hydraulic cylinder 26 is activated. The second hydraulic cylinder 26 drives the guide rollers 14 between the second connecting frames 19 to rise. When the connecting block 28 moves, the ball bearings 29 at the bottom of the connecting block 28 will slide inside the rolling groove 27 and the limiting slide groove 25, thereby improving the stability of the movement of the connecting block 28.

[0027] A mounting bracket 9 is installed at the top of the support frame 3. A drive motor 10 is installed inside the mounting bracket 9. A drive rod 11 is fixedly connected to the output end of the drive motor 10. A rotating block 12 is fixedly connected to the bottom of the front end of the drive rod 11. A frame 8 is provided outside the rotating block 12. A connecting rod 7 is fixedly connected to the bottom end of the frame 8. A pressure plate 5 is fixedly connected to the bottom end of the connecting rod 7. A limit rod 6 is fixedly connected to the top of the left side of the support frame 3. The right side of the limit rod 6 is located outside the connecting rod 7. The connecting rod 7 slides up and down on the right side of the limit rod 6.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, when the drive motor 10 is started, the drive motor 10 drives the rotating block 12 to rotate inside the frame 8 through the drive rod 11. This allows the frame 8 to drive the pressure plate 5 to descend through the connecting rod 7, thereby limiting and fixing the crossbeam at the top of the workbench 2 to prevent the crossbeam from shifting during processing and affecting the bending accuracy. The limiting rod 6 can limit the connecting rod 7 to prevent the connecting rod 7 from driving the pressure plate 5 to move left and right.

[0029] A mounting plate 17 is fixedly connected to the right side of the pressure plate 5, a fixing plate 16 is fixedly connected to the left side of the first connecting frame 15, a first connecting plate 20 is fixedly connected to the bottom end of the second connecting frame 19, and a second connecting plate 21 is installed at the top end of the second hydraulic cylinder 26. Mounting grooves 13 are respectively opened at the upper and lower ends of the fixing plate 16 and the mounting plate 17. Mounting bolts 22 are installed inside the mounting grooves 13. The mounting grooves 13 are machined on the left and right sides of the front and rear ends of the first connecting plate 20 and the second connecting plate 21. The first connecting plate 20 and the second connecting plate 21 are installed and fixed by the mounting bolts 22 and the mounting grooves 13. The fixing plate 16 and the mounting plate 17 are fixed by the mounting grooves 13 and the mounting bolts 22. The fixing plate 16 and the mounting plate 17 are the same size.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, when installing the guide roller 14, the fixing plate 16 on the left side of the fixing plate 16 is placed on the right side of the mounting plate 17. Then, the mounting groove 13 inside the fixing plate 16 and the mounting groove 13 inside the mounting plate 17 are aligned. After alignment, the mounting bolts 22 are screwed into the mounting grooves 13 inside the fixing plate 16 and the mounting plate 17. The guide roller 14 between the first connecting frame 15 and the first connecting frame 15 is installed. After the first connecting frame 15 is installed, the first connecting plate 20 is placed on the top of the second connecting plate 21. During the placement process, the mounting grooves 13 are aligned as well. Then, the mounting bolts 22 are screwed into the inside of the mounting grooves 13 to limit and fix the second connecting frame 19. The guide roller 14 between the second connecting frames 19 is then installed.

[0031] Working Principle: In use, the fixing plate 16 on the left side of the fixing plate 16 is placed on the right side of the mounting plate 17. The mounting grooves 13 inside the fixing plate 16 and the mounting plate 17 are then aligned. After alignment, the mounting bolts 22 are screwed into the mounting grooves 13 inside the fixing plate 16 and the mounting plate 17. The guide rollers 14 between the first connecting frame 15 and the first connecting frame 15 are then installed. After installing the first connecting frame 15, the first connecting plate 20 is placed on top of the second connecting plate 21. During placement, the mounting grooves 13 are aligned again. Then, the mounting bolts 22 are screwed into the mounting grooves 13 to limit and fix the second connecting frame 19. The guide rollers 14 between the second connecting frames 19 are then installed. After installation, the crossbeam to be bent is placed on top of the workbench 2. After placement, the drive motor 10 is started. The drive motor 10 drives the rotating block 12 to rotate inside the frame 8 via the drive rod 11, thereby allowing the frame to be bent. The frame 8 lowers the pressure plate 5 via the connecting rod 7, limiting and fixing the crossbeam at the top of the workbench 2 to prevent it from shifting during processing and affecting the bending accuracy. The limiting rod 6 can limit the connecting rod 7 to prevent it from moving the pressure plate 5 left or right. When it is necessary to adjust the distance between the guide rollers 14, the first hydraulic cylinder 24 is activated. Since the second hydraulic cylinder 26 is installed at the top of the connecting block 28, the first hydraulic cylinder 24 can move the guide rollers 14 between the second connecting frames 19 left or right through the connecting block 28. Adjusting the distance between the guide rollers 14 can easily bend the crossbeam to different angles. After adjustment, the second hydraulic cylinder 26 is activated, which drives the guide rollers 14 between the second connecting frames 19 to rise, thus bending the crossbeam. When the connecting block 28 moves, the ball bearings 29 at the bottom of the connecting block 28 slide inside the roller groove 27 and the limiting slide groove 25, which can improve the stability of the movement of the connecting block 28.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
