[0002] In railway construction and maintenance, rail fastenings are key components to ensure the stability and safety of rails. These fasteners require precise size and shape to fit the connection between rails and sleepers. Track stoppers are an important component of rail fastenings, which are located between the rails and the track bed to support and position the rails.

[0003] At present, when processing track baffles, the track baffles are usually placed manually and bent using a bending device. However, the accuracy of the manual placement of the track baffle bending device is affected by the skill level of the operator and is prone to errors. In addition, during the manual placement of the track baffle bending device, the operator is prone to contact with mechanical equipment, which poses certain safety hazards. Based on the above problems, this application document proposes a bending device for track fastener processing to improve the above problems. Utility Model Content

[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1 , Figure 2 , Figure 4 and Fig. 9As shown, a bending device for processing rail fasteners includes a frame 10, a load-bearing plate 11 is fixed inside the frame 10, a lower die 13 is fixed to one side of the upper end of the load-bearing plate 11, an upper die 14 is fixed to the upper end of the frame 10, and a bending knife 15 is fixed to the lower end of the upper die 14. The device is characterized in that: a first square groove is provided at the lower end of the upper die 14, a first sliding plate 16 is slidably connected to the first square groove, and both ends of the first sliding plate 16 away from the upper die 14 are provided with fixed columns 17, cavities are provided inside the two fixed columns 17, and sliding plates 16 are slidably connected to the two cavities. The movable rod 18, the lower ends of the two movable rods 18 are fixedly connected by an upper clamping plate 19, a second support plate 21 is fixed on one side of the upper mold 14 and at the lower end of the first sliding plate 16, a second square groove is opened in the middle of the second support plate 21, and the second square grooves opened in the first sliding plate 16 and the second support plate 21 are connected by threads, a plurality of circular holes are opened at the upper ends of the two fixed columns 17, positioning pins 22 are penetrated at both ends of the first sliding plate 16, and the positioning pins 22 penetrate the circular holes at the upper ends of the two fixed columns 17, and springs 20 are fixed inside the two fixed columns 17.

[0028] In the above embodiment, when the track baffle is bent, the upper mold 14 pushes the bending knife 15 to move downward. Because the second support plate 21 and the first sliding plate 16 are connected by threads, fixed columns 17 are fixed on both sides of the first sliding plate 16, and the lower end of the fixed column 17 is slidably connected with a moving rod 18, and the lower end of the moving rod 18 is fixed with an upper clamping plate 19. Therefore, when the track baffle is bent, the first sliding plate 16 starts to move downward, and the first sliding plate 16 drives the upper clamping plate 19 to fix the track baffle. It should be noted that before the track baffle is bent, the upper clamping plate 19 is located at the lower end of the bending knife 15, so when the track baffle is fixed, the upper clamping plate 19 first fixes the track baffle. At the same time, the upper mold 14 continues to descend, and the moving rod 18 squeezes the spring 20 to fix the track baffle.

[0029] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, one side of the load-bearing plate 11 is equipped with a moving mechanism 25, and the moving mechanism 25 includes a moving block 26, a support seat 27, a threaded rod 28, a lower clamping plate 29 and a handwheel 30. A T-shaped groove is opened on one side of the load-bearing plate 11, and one side of the moving block 26 is slidably connected in the T-shaped groove. Two support seats 27 are fixed to one side of the load-bearing plate 11 and are located at both ends of the T-shaped groove. The threaded rod 28 is rotatably connected between the two support seats 27, and the threaded rod 28 is rotatably connected to the moving block 26. The lower clamping plate 29 is fixed to the upper end of the moving block 26, and the lower clamping plate 29 is located at the bottom end of the upper clamping plate 19. The handwheel 30 is fixed to one end of the threaded rod 28.

[0030] In the above embodiment, by rotating the hand wheel 30, the hand wheel 30 can drive the threaded rod 28 to rotate, and the rotation of the threaded rod 28 can drive the moving block 26 to move. Because the lower clamping plate 29 is fixed to the upper end of the moving block 26, after the track baffle is placed on the lower clamping plate 29, it can be moved to the lower end of the bending knife 15 of the same size by rotating the hand wheel 30, avoiding the need to replace different bending knives 15 when bending track baffles of various shapes.

[0031] Furthermore, the ends of the lower clamping plate 29 and the upper clamping plate 19 that are close to each other are both provided with anti-slip surfaces, and the anti-slip surfaces are both made of rubber.

[0032] In the above embodiment, the anti-slip surface of the rubber material can increase the friction between the upper clamping plate 19 and the lower clamping plate 29 and the track baffle, preventing the track baffle from sliding due to vibration or other external forces during use. The anti-slip surface of the rubber material can reduce the direct contact between the upper clamping plate 19 and the lower clamping plate 29 and the track baffle, thereby reducing wear and extending the service life of the equipment.

[0033] like Figure 3 and Figure 8 As shown, a first support plate 12 is fixed to the upper end of the load-bearing plate 11, a telescopic motor 31 is fixed to the upper end of the first support plate 12, a fixed plate 32 is fixed to the output end of the telescopic motor 31, a limit plate 33 is fixed to the lower end of the fixed plate 32, and the limit plate 33 is located at the upper end of the first support plate 12, a second sliding plate 34 is fixed to the end of the limit plate 33 close to the hand wheel 30, and a scale 35 is fixed to the upper end of the second sliding plate 34.

[0034] In the above embodiment, the telescopic motor 31 can push the fixed plate 32 to move, the fixed plate 32 can drive the limit plate 33 to move, the limit plate 33 can limit the track baffle, and the setting of the limit plate 33 and the second sliding plate 34 can effectively limit the moving range of the track baffle, avoid errors caused by the movement of the track baffle during bending, and improve the accuracy of adjustment.

[0035] Furthermore, a third groove is formed at one end of the second sliding plate 34 close to the first supporting plate 12 , and a slide rail is formed at one end of the first supporting plate 12 close to the second sliding plate 34 , and the third groove is matched with the slide rail.

[0036] In the above embodiment, the cooperation between the third groove and the slide rail can ensure that the second sliding plate 34 remains stable during the movement and the deviation is reduced.

[0037] Furthermore, a plurality of scale marks are evenly arranged on the upper end of the ruler 35 .

[0038] In the above embodiment, a plurality of scale marks are evenly arranged on the upper end of the ruler 35, so that data can be measured and read quickly and accurately. This design reduces the error when the track baffle is bent and improves the working accuracy.

[0039] The working principle of the utility model is:

[0040] When the track baffle is to be bent, the track baffle to be bent is placed on the lower clamping plate 29. The track baffle placed on the lower clamping plate 29 can be moved to the lower end of the bending knife 15 of the required specification by rotating the hand wheel 30. The distance between the limit plate 33 and the track baffle can be adjusted by the telescopic motor 31. When the ruler 35 is moved to the appropriate position, the first sliding plate 16 is adjusted to be located directly above the lower clamping plate 29. The first sliding plate 16 and the second supporting plate 21 are threadedly connected through the second square groove by bolts. Because the fixing column 17 is fixed on the first sliding plate 16, the fixing column 17 moves downward. When the fixing column 17 moves downward, it squeezes the spring 20, and the spring 20 squeezes the moving rod 18. The moving rod 18 pushes the upper clamping plate 19. The upper clamping plate 19 and the lower clamping plate 29 fix the track baffle. At this time, the bending knife 15 bends the track baffle on the lower mold 13.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
