Description

Technical Field

[0001] This utility model relates to the field of rail forging technology, specifically a rail forging feeding system. Background Technology

[0002] To achieve transitional connections between different types of rails, such as connecting 50AT1, 60AT1, and 60AT2 rails with mainline rails, the rail heel ends need to be forged. For ease of processing and to ensure production efficiency, roller conveyors are typically used to feed the rails to the press. Therefore, ensuring the safe and stable transport of the rails during feeding, while maintaining their straightness with the center of the rail head die, is a problem that urgently needs to be solved. Utility Model Content

[0003] This utility model addresses the problems and defects existing in the above-mentioned background technology by providing a rail forging and feeding system. This feeding system ensures that the rail is smoothly fed to the press and can maintain the same straightness with the center of the rail head die.

[0004] To achieve the above objectives, this utility model provides a rail forging and feeding system, including a feeding roller conveyor. A blocking device and a guiding device are provided on the frame of the roller conveyor. The guiding device is located at one end of the roller conveyor near the press. The guiding device includes a plurality of guide wheels arranged at intervals and symmetrically on both sides of the roller conveyor. Each guide wheel corresponds to the rail web on the roller conveyor. The guide wheels on both sides of the roller conveyor form a rail web channel for the rail web to pass through, so that the outer surface of each guide wheel contacts the rail web on the roller conveyor during the feeding process. The blocking device includes a stop wheel. A plurality of parallel stop wheels are arranged at intervals along the length of the roller conveyor and are located on both sides of the roller conveyor to form a rail channel. The top surface of each stop wheel is higher than the tread surface of the rail, so that the outer surface of each stop wheel contacts the corresponding side of the rail head during the feeding process. This technical solution achieves safe and stable transport of the rails by setting a material blocking device on the roller conveyor; and by setting a guiding device at the end of the roller conveyor near the press, it guides the rail web to ensure that the straightness of the rail and the center of the rail head die is consistent, thereby improving the processing accuracy.

[0005] Furthermore, the material blocking device also includes a guide wheel seat mounted on the frame. The guide wheel is rotatably mounted on the guide wheel seat via an axle. The guide wheels are symmetrically arranged on both sides of the frame. The guide wheels are cylindrical and arranged vertically.

[0006] Furthermore, guard plates are provided on both sides of the retaining wheel. These guard plates have a trapezoidal structure, wider at the top and narrower at the bottom, such that the upper part of the retaining wheel extends beyond the corresponding guard plate by a greater width than the lower part of the retaining wheel extends beyond the guard plate. The guard plates prevent the rail from damaging the retaining wheel, ensuring its service life.

[0007] Furthermore, the guiding device also includes a guide wheel seat mounted on the frame, wherein the guide wheel is rotatably mounted on the guide wheel seat, and the guide wheel is disc-shaped and horizontally arranged.

[0008] Furthermore, reinforcing blocks are provided on both the upper and lower surfaces of the guide wheel. The reinforcement blocks increase the contact area between the guide wheel and the axle, thereby improving the durability of the axle.

[0009] Furthermore, the rail forging and feeding system also includes a limiting device, which is located at one end of the roller conveyor near the press.

[0010] Furthermore, the limiting device includes at least a pair of opposing wedges adapted to the rail web. These wedges are telescopically positioned on both sides of the roller conveyor at the rail web corresponding to the rail on the roller conveyor, and are inserted into and wedged into the rail web under the drive of a telescopic rod. The limiting device prevents the rail from moving during the forming process, thereby ensuring processing accuracy.

[0011] Furthermore, the wedge block is detachably mounted on one end of the telescopic rod via a connecting plate.

[0012] Compared with the prior art, the present invention has the following technical effects:

[0013] 1. The rail forging and feeding system of this utility model achieves safe and stable rail transportation by setting a baffle device on the roller conveyor. The baffle device contacts the side of the rail head through the baffle wheel, which can prevent the rail from tipping over during transportation and also plays a guiding role to ensure the stability of rail transportation.

[0014] 2. This utility model uses a guiding device installed at one end of the roller conveyor near the press to guide the rail web, ensuring that the straightness of the rail and the center of the rail head die are consistent, thereby improving processing accuracy;

[0015] 3. This utility model provides guard plates on both sides of the retaining roller. The guard plates adopt a trapezoidal structure that is larger at the top and smaller at the bottom, so that the upper part of the retaining roller exceeds the width of the corresponding guard plate by more than the lower part of the retaining roller exceeds the width of the guard plate. This prevents the rail from damaging the retaining roller when it enters between the two retaining rollers, especially the retaining roller located at the end of the roller conveyor away from the press, thus ensuring the service life of the retaining roller. This utility model is highly practical.

[0016] 4. This utility model uses a limiting device to limit the rail movement during the forming process, preventing displacement and ensuring processing accuracy. Furthermore, it employs a wedge block that engages with the rail web to hold it in place. The wedge block contacts the side of the rail web, the lower surface of the rail head, and the upper surface of the rail base. This large contact area not only increases the friction between the wedge block and the rail, thus limiting the rail movement, but also makes the rail more stable during the forging process. Compared to a smaller contact area, this reduces the chance of rail damage and is safer. Attached Figure Description

[0024] This utility model provides a rail forging and feeding system, such as Figure 1 As shown, when using this feeding system, the feeding system is arranged on one side of the press 200, so as to feed the heel end of the rail 300 onto the worktable of the press 200.

[0025] The following is in conjunction with the appendix Figure 1 , 2 Sections 3 and 4 provide a detailed description of the embodiments of this utility model:

[0026] Example 1: As Figure 1 and 2As shown, the rail forging feeding system of this embodiment includes a feeding roller conveyor 100, which is fixed to the workshop floor by adjusting bolts 700. A material blocking device 400 and a guiding device 500 are provided on the frame 110 of the roller conveyor 100. The guiding device 500 is located at one end of the roller conveyor 100 near the press 200. The guiding device 500 includes guide wheels 510 arranged symmetrically on both sides of the roller conveyor 100. The guide wheels 510 correspond to the rail web of the rail 300 on the roller conveyor 100. The guide wheels 510 on both sides of the roller conveyor 100 form a rail web channel for the rail web to pass through, so that the outer surface of each guide wheel 510 contacts the rail web of the rail 300 on the roller conveyor 100 during the feeding process, thereby playing a guiding role, ensuring that the straightness of the rail and the center of the rail head die is consistent, and improving the accuracy of the forming.

[0027] In this embodiment, the material blocking device 400 includes a guide wheel 410. A plurality of material blocking devices 400 are arranged at intervals along the length of the roller conveyor 100 and are located on both sides of the roller conveyor 100 to form rail head channels. That is, material blocking devices 400 are provided on both sides of the entire roller conveyor 100. The material blocking devices 400 not only prevent the rails from tipping over during transmission but also play a certain guiding and limiting role. The top surface of the guide wheel 410 is higher than the tread surface of the rail 300 so that during the feeding process, the outer circumference of each guide wheel 410 contacts the corresponding side of the rail head of the rail 300.

[0028] In this embodiment, the roller conveyor 100 includes feeding rollers 120 and a frame 110. A plurality of spaced feeding rollers 120 are rotatably mounted on the frame 100. Roller conveyors, also known as roller conveyor lines, are commonly used conveying equipment; their structural composition will not be detailed here. See [link to relevant documentation]. Figure 3 The material blocking device 400 also includes a guide wheel seat 420 mounted on the frame 110. The guide wheel 410 is rotatably mounted on the guide wheel seat 420 via a wheel axle 411. The guide wheels 410 located on both sides of the frame 100 are symmetrically arranged. The guide wheels 410 are cylinders and are arranged vertically.

[0029] like Figure 3As shown, the structure of the wheel stop seat in this embodiment is as follows: The wheel stop seat 420 includes a vertically arranged upright plate 422. A fixing plate 423 is fixedly connected to the bottom of the upright plate 422 and is perpendicular to it. Reinforcing ribs 424 are provided on both sides of the fixing plate 423 to connect the fixing plate 423 and the upright plate 422. The reinforcing ribs 424 improve the stability of the connection between the upright plate 422 and the fixing plate 423, thereby improving the stability of the wheel stop seat 420. Mounting holes are provided at the four corners of the fixing plate 423. The wheel stop seat 420 is connected to the frame 110 through the mounting holes on the mounting plate 423 and the bolts installed in the mounting holes. An elongated hole is provided on the frame 110. This design facilitates the adjustment of the position of the wheel stop seat 420. On the upright plate 422, above the fixed plate 423, there are parallel lower mounting plates 425 and upper mounting plates 426. The lower mounting plates 425 and upper mounting plates 426 are connected to the upright plate 422. The height of the lower mounting plate 425 is higher than the upper surface of the rail base of the rail 300 to prevent interference with the rail. The upper and lower ends of the retaining wheel 410 are respectively mounted on the upper mounting plate 426 and lower mounting plate 425 via axles 411. Both ends of the retaining wheel 410 are connected to the axles 411 via bearings. The upper and lower ends of the axles 411 are fixedly connected to the upper mounting plate 426 and lower mounting plate 425, respectively. For ease of assembly, the upper mounting plate 426 is connected to the upright plate 422 by bolts.

[0030] In this embodiment, to prevent the rail head from damaging the stop roller 410 when it passes over it during use, guard plates 421 are provided on both sides of the stop roller 410. The guard plates 421 have a trapezoidal structure that is wider at the top and narrower at the bottom, such that the upper part of the stop roller 410 extends beyond the corresponding guard plate 421 by a greater width than the lower part of the stop roller 410 extends beyond the guard plate 421. The bottom of the guard plate 421 is fixedly connected to the lower mounting plate 425, and its side is fixedly connected to the inner surface of the vertical plate 422. The guard plate 421 is bolted to the upper mounting plate 426 (not shown in the figure).

[0031] In this embodiment, as Figure 1As shown, the guiding device 500 also includes a guide wheel seat 520 mounted on the frame 110. The guide wheel 510 is rotatably mounted on the guide wheel seat 520. The guide wheel 510 is disc-shaped and horizontally arranged. Reinforcing blocks 530 are provided on both the upper and lower surfaces of the guide wheel 510. The reinforcing blocks 530 increase the contact area between the guide wheel 510 and the guide wheel shaft, and also facilitate bearing installation. The reinforcing blocks 530 are bolted to the guide wheel 510. The guide wheel seat 520 consists of two vertically arranged vertical plates and a portal-shaped structure connected to the top surface of the two vertical plates. Its bottom is bolted to the frame 110. A support plate 540 is provided between the two vertical plates of the guide wheel seat. The two ends of the support plate 540 are fixedly connected to the two vertical plates of the guide wheel seat. The horizontal plate at the top of the portal-shaped guide wheel seat is bolted to the two vertical plates. The guide wheel 510 and the reinforcing blocks 530 disposed on its upper and lower surfaces are disposed on the support plate 540 and between the two vertical plates and the horizontal plate of the guide wheel seat 520. The two ends of the guide wheel shaft are connected to the support plate 540 and the horizontal plate, respectively. The diameter of the reinforcing block 530 is smaller than the diameter of the guide wheel 510, and the width of the guide wheel 510 is larger than the width of the guide wheel seat 520, so that the guide wheel 510 extends out of the guide wheel seat 520 and contacts the rail web.

[0032] When the conveying system of this embodiment uses the press 200 to convey the rails, the stop device 400 prevents the rails 300 on the roller conveyor 100 from tipping over during the conveying process, and at the same time limits the rail head. The guide device 500 is set at one end of the roller conveyor 100 near the press. In this embodiment, there are two guide devices 500, which are arranged at intervals to limit and guide the rail web of the rail 300 so that the straightness of the rail and the center of the rail head mold is consistent.

[0033] Example 2: To prevent the rail from shifting backward during the forging process, this example adds a limiting device 600 based on Example 1. The specific structure of the limiting device 600 is as follows: See Figure 1A limiting device 600 is located at one end of the roller conveyor 100 near the press 200. The limiting device includes at least one pair of opposing wedges 610, which are adapted to the rail web. The wedges 610 are telescopically positioned on both sides of the roller conveyor 100 at the rail web corresponding to the rail on the roller conveyor 100, so as to insert and wed the rail web under the drive of the telescopic rod 620. The cross-sectional shape of the wedges 610 is consistent with the cross-sectional shape and size of the rail 300. Specifically, the telescopic rod 620 is mounted on the frame 110 via an L-shaped fixing bracket. The telescopic rod 620 is horizontally arranged, and one end is connected to the wedges 610 via a connecting plate 640. One end of the telescopic rod 620 is fixedly connected to the connecting plate 640, and the wedges 610 are bolted to the connecting plate 640 for easy replacement of the wedges 610 to meet the production of different rail models. The length and width of the connecting plate 640 are both smaller than the length and width of the connection surface with the wedges 610. In this embodiment, when the rail 300 stops advancing, the telescopic rod drives the wedge block 640 to wedge into the rail web, thereby limiting the rail 300 and preventing it from rolling back. In this embodiment, the telescopic rod 620 is a hydraulic cylinder, which is fixedly mounted on the fixing frame 630. In other embodiments, the hydraulic cylinder can be replaced by a screw, in which case the screw is threadedly connected to the fixing frame. In this embodiment, when the rail 300 stops advancing, the telescopic rod drives the wedge block 640 to extend into the rail web, wedging it in place, thereby limiting the rail 300 and preventing it from rolling back, ensuring processing accuracy.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
