Description

Technical Field

[0001] The present invention belongs to the technical field of workpiece turnover for operation and transportation, and particularly relates to a horizontal turnover device for machining flash of profiled steel rails during forging and its usage method. Background Art

[0002] In today's railway rail processing industry, especially among the four major domestic turnout processing enterprises, for the processing of rail components in rail forging and subsequent processes, the processes are basically the same. For the turnover of rails to adapt to rail processing, the adopted methods are relatively single. In the rail forging production line, turnover trolleys are generally used for the turnover of rail components (see the Chinese patent with the publication number CN202239466U and the patent name: Clamp Rotation Device of Precision Forging Process Production Line for Railway Turnouts), that is, the rail components with the rail bottom facing down in the storage area are taken with the rail bottom facing down according to the die state, turned over 90° laterally or 180° inverted and then put into the die. After forging, the materials are discharged again with the rail bottom facing down to complete the state control of the rail components; in other processes, due to the low degree of automation, manual material turning and prying methods are generally used to turn the rail components 90° laterally or 180° inverted.

[0003] A horizontal turnover device for machining flash of profiled steel rails involved in this patent is completely different from the existing forging production line. It is mainly used for flash machining and grinding operations in the transition section area after rail forging, and cooperates with the flash machining production line to control the state of rail components. The flash machining production line after rail forging has a total of 6 zones, and their functions are different. Specifically as Figure 1 、 Figure 2 shown: There are great differences between the technological process requirements of flash machining of rail components and the material turning state of rail components during rail forging. The biggest difference is that when machining the flash of rail components, after the rail bottom of the rail is turned over 180° with the rail bottom facing down and then facing up, the rail components with the rail bottom facing up need to be able to be horizontally and longitudinally transported in each operation station area without being affected by the turnover device, and at the same time, it does not affect the turnover and flash machining operations of other rail components at other stations.

[0004] The existing rail turnover device in the rail forging production line cannot meet this particularity of the flash machining operation of rail components. After the rail bottom is turned over, the turnover trolley and the rail component are rigidly connected and relatively stationary, and cannot be separated. The rail component with the rail bottom facing up after turning over cannot be separated from the trolley and operate independently. Therefore, the existing feeding trolley in the rail forging production line cannot meet the feeding and turnover requirements of the flash machining operation after rail forging. It is necessary to re - design, so the following technical solutions are proposed. Summary of the Invention

[0005] Technical problems to be solved by the present invention: Provide a horizontal turning device for machining flash of profiled steel rails and its usage method, and solve the technical problem that the existing rail turning device in the rail forging production line cannot meet the special and efficient continuous machining requirements of flash machining of rail parts.

[0006] Technical solution adopted by the present invention: A horizontal turning device for machining flash of profiled steel rails, the horizontal turning device for machining flash of profiled steel rails sequentially has a loading conveying station, a loading turning station, a loading connection station, a discharging connection station, a discharging turning station and a discharging conveying station; The loading conveying station is provided with a loading conveying mechanism, and a cylinder lateral positioning mechanism is arranged at the end of the loading conveying mechanism; At the execution end of the cylinder lateral positioning mechanism and beside the loading turning station, there is a first electric turning clamping mechanism; After the first electric turning clamping mechanism clamps the rail parts included in the clamping cavity up and down, the first electric turning clamping mechanism turns the rail parts clockwise by 180° to make the rail bottom face up and the rail head face down; And the rail parts after turning are connected by a connection mechanism arranged at the loading connection station on the right side of the first electric turning clamping mechanism; The end of the connection mechanism is the discharging connection station; The discharging connection station is connected with a second electric turning clamping mechanism; After the second electric turning clamping mechanism clamps the rail parts included in the clamping cavity up and down, it turns the rail parts clockwise by 180° to make the rail bottom face down again and the rail head face up again; And the working station after the second electric turning clamping mechanism turns is the discharging turning station; And the discharging turning station is connected with a discharging conveying mechanism.

[0007] The first electric turning clamping mechanism and the second electric turning clamping mechanism have the same structure and have a turning support, and an 180° turning body is installed on the turning support; The turning body includes a clamping cylinder fixedly installed vertically, and a pressing clamping plate is installed at the execution end of the clamping cylinder and drives the pressing clamping plate to perform a pressing clamping action; A clamping bottom plate is arranged directly above and below the pressing clamping plate; The pressing clamping plate and the clamping bottom plate apply clamping pressure up and down to clamp the rail parts; And a turning proximity switch is installed on the clamping bottom plate; The turning body further includes an electric drive turning assembly.

[0008] The electric drive turning assembly includes a turning power motor, and the turning power motor drives the upper through-turning main shaft to rotate through a chain drive; The through-turning main shaft drives the sleeve to rotate through a keyway; The sleeve is fixedly connected with the turning body as a whole to realize the rotation of the turning body.

[0009] It also includes upper and lower material pushing claws and a cylinder lateral positioning detection proximity switch; The upper and lower material pushing claws are respectively used for pushing the rail parts of the loading conveying mechanism and the discharging conveying mechanism; The cylinder lateral positioning detection proximity switch is used to trigger the cylinder lateral positioning mechanism to perform a material pushing action after the rail parts reach the position.

[0010] The butt joint mechanism includes a multi-station shuttle car, longitudinal feeding rollers for steel rails, and a liftable inverted support; the multi-station shuttle car is equipped with a shuttle car track.

[0011] It also includes a bearing part, which is used to lubricate the flipping of the flipping body.

[0012] It also includes a guide groove and a guide groove cover plate; the guide groove provides linear guidance for the vertical downward pressing of the downward pressing clamping plate; the guide groove cover plate is used to increase the structural support strength of the downward pressing clamping plate.

[0013] The cylinder lateral positioning mechanism includes a double-stroke cylinder and a cylinder pusher head that are horizontally and transversely fixedly installed at the tail of the feeding conveyor mechanism; the cylinder pusher head is fitted with the bottom of the rail member to push the rail member into the feeding flipping station.

[0014] The inverted support is lifted by a cylinder or an oil cylinder; the inverted support uses a three-sided constraint method at the bottom and on the left and right sides to constrain and fix the rail member with the rail head facing down and the rail bottom facing up after flipping.

[0015] The present invention also claims protection for a method of using a horizontal flipping device for processing flash on profiled steel rails, including the horizontal flipping device for processing flash on profiled steel rails described in any one of the above, and the method of using the device includes the following steps:

[0016] S1. Pushing by the feeding pusher claw: After starting the operation, the feeding pusher claw at the feeding station pushes the rail member to the feeding flipping station;

[0017] S2. Cylinder pushing and positioning: When the rail member reaches the feeding flipping station, the proximity switch of the cylinder lateral positioning detection sends a signal, the feeding pusher claw stops pushing, and the cylinder lateral positioning mechanism performs the pushing action;

[0018] S3. Clamping by the clamping plate: After the rail member is pushed to the extreme position by the cylinder lateral positioning mechanism, the turning material proximity switch sends a signal, the clamping cylinder drives the downward pressing clamping plate to perform the downward pressing and clamping action, and clamps the rail member between the downward pressing clamping plate and the clamping bottom plate; at the same time, the feeding pusher claw at the feeding station retracts to the storage area to prepare to push the next rail member;

[0019] S4. Flipping: When the pressure of the clamping cylinder reaches the set value, the flipping power motor is started, driving the flipping body to flip clockwise by 180°, and when the flipping power motor reaches the set flipping angle, the flipping power motor stops operating, completing the flipping of the rail member;

[0020] S5. Butt joint and material receiving: The liftable inverted support in the multi-station shuttle car is lifted. After reaching the set height, the clamping cylinder of the first electric flipping and clamping mechanism releases the pressure to loosen the rail member, the rail member descends and falls into the inverted support. After the downward pressing clamping plate is completely opened, the multi-station shuttle car starts to move horizontally;

[0021] S6, docking and feeding: the multi-station shuttle vehicle starts horizontally to the processing area and moves the flipped rail parts out of the loading docking station;

[0022] S7, flip back to zero: the second electric flip clamping mechanism flips the rail piece 180° clockwise and then resets it to zero position, waiting for the next rail piece to flip;

[0023] S8, unloading and conveying: The turned and reset rail parts are conveyed along the unloading and conveying station by the unloading and conveying mechanism.

[0024] The advantages of the present invention compared with the prior art are:

[0025] The present invention is used for turning over and controlling the position of special-shaped rails, and can be particularly applied to intelligent manufacturing of turnouts. It is used to turn over the rails by ±180° from the rail bottom downward during flash processing, thus meeting the production requirements of rail bottom flash processing, inspection, and synchronous and efficient operation of multiple rail parts. It realizes the continuous turning over of multiple rail parts during flash processing, and properly solves the problem of automated turning over of rail bottom upward processing in the industry for more than 30 years.

[0026] The present invention arranges two groups of turning devices in the flash processing production line, one group on the loading side and one group on the unloading side; the turning device on the loading side is mainly used to prepare the turning and loading operation of the rail parts to be processed. After the rail parts are turned over, they enter the processing waiting area for flash processing sorting; the turning device on the unloading side is mainly used to complete the flash processing and check and confirm the processing quality after the flash processing rail parts are prepared for unloading operations. After the rail parts are turned over, they are promptly stored in the unloading area for storage, which is convenient for other subsequent operations such as the circulation of the rail parts.

[0027] Between the feeding group turning device and the unloading turning device of the present invention, after the rail is turned over, an independent rail docking device promptly removes the operating rail from the feeding turning position, and the feeding turning device performs subsequent rail turning operations, replenishes and turns materials in time, and ensures continuous turning production operations at the feeding station.

[0028] The side entry method of the present invention is completely different from the existing feeding production line in the rail processing industry. The lateral rail turning can effectively ensure that the rail bottom of the rail piece faces upward and flows to each workstation after turning. The direction of the rail bottom surface always remains open without interference from mechanical mechanisms, which is convenient for the turning mechanism to disengage and the rail piece to be taken out of each workstation.

[0029] When the present invention is applied specifically, the staggered longitudinal arrangement of loading, turning and connecting as shown in the figure, combined with the setting of four turning stations for the flipping operation, effectively solves the problems of preparation, clamping, connecting, turning and signal control connection with the position status of the rail as the node for rail turning; this flipping method is the first of its kind in the industry, and it provides a solution and application precedent for automatic loading operations for each process of rail bottom-up processing, and has a positive demonstration effect.

[0030] The structure of the present invention is reasonable, simple and practical, with strong versatility, convenient installation and maintenance, facilitating design and construction, applicable to the production of steel track switches, and can be widely used in the fields of automatic feeding and turning of rail parts; the present invention is fully applicable to working conditions such as high temperature, high oil fume, high daily output, high noise, high vibration, high frequency, long-distance vision, and long duration of labor intensity, and is suitable for popularization.

Detailed implementation method

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached Figure 3-16 drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] The present invention claims a method for using a horizontal tipping device for machining flash of profiled steel rails during forging, including the horizontal tipping device for machining flash of profiled steel rails, and the method comprises the following steps:

[0050] (As Figure 15 shown) A method for using a horizontal tipping device for machining flash of profiled steel rails related to the present invention, including the horizontal tipping device for machining flash of profiled steel rails, and the method comprises the following steps:

[0051] (As Figure 9 shown) S1. Pushing the material by the feeding push claws: After starting the operation, the feeding push claws at the feeding conveying station 1 push the rail parts to the feeding tipping station 2.

[0052] (As Figure 9 shown) S2. Positioning the material by the cylinder pusher: When the rail parts reach the feeding tipping station 2, the cylinder lateral positioning detection proximity switch 12 sends a signal, that is, the cylinder lateral positioning detection proximity switch 12 detects that the rail parts are in place, and then sends a signal to make the feeding push claws stop pushing the material, and the cylinder lateral positioning mechanism 8 performs the pushing action.

[0053] (as shown in Figure 9 Figure) S3. Clamping by splint: After the rail member is pushed to the extreme position by the cylinder lateral positioning mechanism 8, the approaching switch 905 for turning over the material at the extreme position sends a signal, triggering the clamping cylinder 902 to drive the downward pressing clamping plate 903 to perform the downward pressing and clamping action, clamping the rail member between the downward pressing clamping plate 903 and the clamping bottom plate 904; at the same time, the feeding pusher claw at the feeding conveying station 1 retracts to the storage area to prepare for pushing the next rail member.

[0054] (as shown in Figure 12 Figure) S4. Turning over: When the pressure of the clamping cylinder 902 reaches the set value, the turning power motor 906 starts, driving the turning body 9011 to turn clockwise by 180°, and when the turning power motor 906 reaches the set turning angle, the turning power motor 906 stops operating, completing the turning over of the rail member.

[0055] (as shown in Figure 13 Figure) S5. Connecting and receiving: The liftable inverted support 1003 in the multi-station connecting vehicle 1001 lifts. After reaching the set height (not reaching the height of contacting the rail, the difference in distance from the rail member can be set to 3 - 10 mm), the clamping cylinder 902 of the first electric turning and clamping mechanism 9-1 releases the pressure to loosen the rail member, and the rail member descends and falls into the inverted support 1003. After the downward pressing clamping plate 903 is fully opened, the multi-station connecting vehicle 1001 starts to move horizontally.

[0056] (as shown in Figure 14 Figure) S6. Connecting and moving: The multi-station connecting vehicle 1001 starts to move horizontally to the processing area, moving the turned-over rail member out of the feeding connecting station 3.

[0057] S7. Returning the turning to zero: The second electric turning and clamping mechanism 9-2 turns the rail member clockwise by 180° and then resets to the zero position, waiting for the turning of the next rail member.

[0058] S8. Downward feeding and conveying: The rail member after turning and resetting is conveyed by the downward feeding conveying mechanism 13 along the downward feeding conveying station 6.

[0059] A horizontal turning device for machining the flash of profiled steel rails; (as shown in Figure 3 Figure) It successively has a feeding conveying station 1, a feeding turning station 2, a feeding connecting station 3, a downward feeding connecting station 4, a downward feeding turning station 5, and a downward feeding conveying station 6 from left to right.

[0060] In the above embodiment, further: The feeding conveying station 1 is provided with a feeding conveying mechanism 7, and the feeding conveying mechanism 7 is used for feeding and conveying the rail member. The transmission chain of the feeding conveying mechanism 7 is installed with the above-mentioned upper and lower feeding pusher claws 11. The feeding conveying mechanism 7 can be a chain drive mechanism combined with a transmission roller structure.

[0061] A cylinder transverse positioning mechanism 8 is provided at the end of the feeding and conveying mechanism 7; the cylinder transverse positioning mechanism 8 is used to push the rail into the clamping cavity. A first electric flip clamping mechanism 9-1 is provided at the execution end of the cylinder transverse positioning mechanism 8 and beside the feeding and flipping station 2; the first electric flip clamping mechanism 9-1 clamps the rail placed in the clamping cavity up and down; the first electric flip clamping mechanism 9-1 flips the rail 180° clockwise so that the bottom of the rail faces upward and the head of the rail faces downward. Afterwards, the flipped rail is docked by the docking mechanism 10 provided at the feeding and docking station 3 on the right side of the first electric flip clamping mechanism 9-1; the docking mechanism 10 is used to receive the flipped rail, process the burrs of the flipped rail, and transport the rail after processing.

[0062] The end of the docking mechanism 10 is the material unloading docking station 4; the material unloading docking station 4 is connected to the second electric flip clamping mechanism 9-2; the second electric flip clamping mechanism 9-2 is used for the re-flipping and resetting operation of the rail. That is, the rail is restored to the rail head facing up and the rail bottom facing down. After the second electric flip clamping mechanism 9-2 clamps the rail part inserted into the clamping cavity up and down, it flips the rail part 180° clockwise to turn the rail bottom down again and the rail head up again.

[0063] The workstation after the flipping of the second electric flipping clamping mechanism 9-2 is the blanking flipping workstation 5, and the blanking flipping workstation 5 is connected to the blanking conveying mechanism 13. The blanking conveying mechanism 13 is used to continue to convey the rail piece that has been flipped and reset to zero position to the next process.

[0064] In the above embodiment, further: the first electric flip clamping mechanism 9 - 1 and the second electric flip clamping mechanism 9 - 2 have the same structure.

[0065] In specific implementation, the first electric flip clamping mechanism 9-1 and the second electric flip clamping mechanism 9-2 respectively have a flipping support 901 (such as Figure 5 , Figure 6 , Figure 7 The material turning support 901 is made of profiles welded together. The material turning support 901 is installed with a 180° turning body 9011. The turning body 9011 includes an electric drive turning component and a turning clamping component.

[0066] The flipping clamping assembly of the flipping body 9011 includes a clamping cylinder 902 which is fixedly installed vertically. The clamping cylinder 902 performs the end installation of the pressing clamping plate 903 and drives the pressing clamping plate 903 to perform the pressing clamping action.

[0067] A clamping bottom plate 904 is provided directly above and below the pressing and clamping plate 903. The pressing and clamping plate 903 and the clamping bottom plate 904 apply clamping pressure in the up and down directions to clamp the rail member. The clamping bottom plate 904 is equipped with a turning material proximity switch 905. The turning material proximity switch 905 is used to detect whether the rail member has completely fallen into the clamping and fixing cavity. Once the rail member has fallen in, the turning material proximity switch 905 triggers the execution of the turning action.

[0068] The turning body further includes an electric drive turning assembly. In the above embodiment, preferably, the electric drive turning assembly includes a turning power motor 906. The turning power motor 906 drives the rotation of the upper through-turning main shaft 907 through chain drive (combined with Figure 4 the isometric drawing); the through-turning main shaft 907 drives the rotation of the bushing 908 through a keyway (see Figure 6 ); the keyway transmission method is adopted, with a simple structure, convenient processing, and reliable transmission. The bushing 908 is fixedly connected to the turning body as a whole to realize the rotation of the turning body 9011.

[0069] It can be seen that the function of the turning body is to realize the overall clamping and turning of the rail. The turning body is a key structure. The turning material proximity switch 905 provided at the bottom is used to determine whether the rail member has completely fallen into the clamping cavity and trigger the execution of the turning action for the rail member that has completely fallen into the clamping cavity. The clamping cylinder 902 is used to execute the clamping action. The clamping and fixing method of the rail member adopts the method of applying pressure from above and below. After the rail is pushed into the clamping cavity of the turning material mechanism by the cylinder, the proximity switch at the bottom of the rail bottom plate of the turning component sends a signal, and the clamping cylinder presses down, applying pressure through the rail top to tightly press the rail bottom of the rail member on the clamping bottom plate to achieve fixation.

[0070] (as Figure 16 shown) As for the turning power group: that is, the mechanism used to realize the turning action of the rail member. When the rotation direction shown in the figure is clockwise, the synergistic effect of the cylinder lateral positioning mechanism 8 and the clamping mechanism can be effectively utilized to form a stable side pressing and turning vertical surface, thereby forming the support on the side and upper and lower sides of the rail bottom of the rail member.

[0071] (see again Figure 16 the embodiment state) The turning vertical surface is located in the pushing and feeding direction of the cylinder lateral positioning mechanism 8 of the loading rack, serving as the final positioning and clamping position for lateral pushing, that is, the cylinder pushing head of the cylinder lateral positioning mechanism 8 clamps the rail laterally and sidewise, cooperating with the detection sensor, and forming a three-sided clamping effect during the horizontal push to achieve horizontal static positioning, and combined with the rapid turning action, to achieve alternating turning and conveying.

[0072] It should be emphasized and stated that: the purpose of the synergistic effect of the cylinder lateral positioning mechanism 8 and the clamping mechanism is: even if the pressure of the clamping cylinder or oil cylinder is relieved, it can ensure that the rail member is always located in the turning cavity during the initial turning process to prevent accidental dropping.

[0073] The process is as follows: when turning over, the turning face is always on the lower side of the rail. When clamped normally, the proximity switch of the rail bottom turning device always sends a signal to indicate that the rail is clamped normally. When the clamping cylinder is depressurized, the rail will be separated from the rail bottom plate during the turning process and fall to the turning face. Since the turning face is always on the lower side of the rail, it will take over the clamping of the rail to a certain extent, and the proximity switch of the rail bottom turning device will send a signal to stop. This mechanism can effectively ensure the turning safety of the rail, so it is safer and more reliable.

[0074] In the above embodiments, further: Embodiment 1: also includes a sliding sleeve, and the sliding sleeve is used to lubricate the flipping of the flip body 9011.

[0075] Embodiment 2: It also includes a bearing member, and the bearing member is used to lubricate the flipping of the flip body 9011.

[0076] In the above embodiment, further: the pressing clamping plate 903 further includes a guide groove 909 and a guide groove cover plate 910; (such as Figure 6 The guide groove 909 provides a linear guide for the vertical downward pressing of the pressing clamping plate 903; the guide groove cover plate 910 is used to increase the structural support strength of the pressing clamping plate 903. The guide groove cover plate 910 is welded with profiles to form an inverted U-shaped structure.

[0077] In the above embodiment, further: it also includes upper and lower material pushing claws 11 and a cylinder lateral positioning detection proximity switch 12.

[0078] The cylinder transverse positioning detection proximity switch 12 is used to detect whether the rail has reached the push positioning position. When the rail reaches the push positioning position, the cylinder transverse positioning mechanism 8 is triggered to perform the push positioning operation. That is, the upper and lower material pushing claws 11 are used to push the rails of the upper material conveying mechanism 7 and the lower material conveying mechanism 13 respectively; the cylinder transverse positioning detection proximity switch 12 is used to trigger the cylinder transverse positioning mechanism 8 to perform the pushing action after the rail is in place.

[0079] (like Figure 3 In the above embodiment, preferably: the cylinder lateral positioning mechanism 8 includes a two-way stroke cylinder 801 and a cylinder pushing head 802 which are fixedly installed horizontally and laterally at the conveying tail of the feeding conveying mechanism 7.

[0080] The cylinder pusher 802 is a vertical structure perpendicular to the horizontal direction. The cylinder pusher 802 is used to fit the rail bottom to push the rail into the loading and flipping station 2. That is, when the rail arrives at the pushing station, the bidirectional stroke cylinder 801 is triggered to perform the pushing action, thereby pushing the rail into the clamping and fixing cavity.

[0081] (likeFigure 3 In the above embodiments, further: The butt joint mechanism 10 includes a multi-station shuttle car 1001, a longitudinal rail feeding roll 1002, and a liftable inverted support 1003.

[0082] The multi-station shuttle car 1001 is equipped with a shuttle car ground rail 10011 (as Figure 4 , Figure 8 shown). The multi-station shuttle car 1001 can move along the shuttle car ground rail 10011.

[0083] In addition, the inverted support 1003 is driven to lift by a lifting cylinder or an oil cylinder to restrain the rail member. That is, the inverted support 1003 is fixedly connected to the top of the lifting cylinder or the oil cylinder and rises and falls with the lifting cylinder or the oil cylinder, so as to restrain the inverted rail member on three sides through the inverted support 1003.

[0084] In the above embodiments, further: The inverted support 1003 is lifted by a cylinder or an oil cylinder; the inverted support 1003 restrains and fixes the rail member with the rail head facing down and the rail bottom facing up in a way of three-sided restraint at the bottom and on the left and right sides.

[0085] It can be found from the above description that: The present invention is used for the turning and position control of special-shaped steel rails, especially can be applied to the intelligent manufacturing of turnouts; during the flash machining process, the steel rail is turned by ±180° with the rail bottom facing down to meet the production requirements of flash machining, inspection, and synchronous and efficient operation of multiple rail members; during the flash machining operation, continuous turning operations of multiple rail members are realized, and the automation turning operation problem of machining with the rail bottom facing up in the industry for more than 30 years is properly solved.

[0086] The working principle needs to be combined with Figure 16 the technical solutions and embodiments: Two sets of turning devices are arranged in the flash machining production line of the present invention, one set on the loading side and one set on the unloading side; the turning device on the loading side is mainly used for preparing the turning and loading operation of the rail member to be processed. After the rail member is turned, it enters the processing waiting area for flash machining sorting; the turning device on the unloading side is mainly used for preparing the unloading operation of the flash machined rail member after completing the flash machining and checking and confirming the machining quality. After the rail member is turned, it is timely stored in the unloading area for storage, which is convenient for subsequent operations such as the transfer of the rail member.

[0087] Between the loading group turning device and the unloading turning device of the present invention, after the rail member is turned, an independent rail member butt joint device timely removes the working rail member from the loading turning position. The loading turning device performs subsequent rail member turning operations, timely replenishes and turns the materials to ensure continuous turning production operations at the loading station.

[0088] The side-in position mode of the present invention is completely different from the feeding production line in the existing rail processing industry. The side rail turning can effectively ensure that the rail bottom of the rail piece faces upward during the transfer of each working station, and the direction of the rail bottom surface always remains open without mechanical interference, which is convenient for the turning mechanism to disengage and the rail piece to be picked up at each working station.
