Description

Technical Field

[0001] This invention relates to the field of profile roll forming technology, and more specifically, to a high-efficiency roll forming device and method for pre-embedded profiles in high-speed railway tunnels. Background Technology

[0002] In existing technologies, high-efficiency roll forming devices for pre-embedded profiles in high-speed railway tunnels typically employ multiple sets of forming rollers to continuously roll the profiles at high speeds to achieve mass production. However, as the rolling speed increases, the contact friction between the profile surface and the forming rollers increases significantly. This not only exacerbates roller wear and profile surface scratches but also affects the dimensional accuracy and mechanical properties of the profiles due to accumulated frictional heat. The most direct method to reduce friction in existing technologies is to apply lubricating oil. However, lubricating oil significantly reduces the coefficient of friction between the forming rollers and the profiles during high-speed rolling, causing the profiles to slip, deviate, or even fail to be fed smoothly under the action of rolling traction force. This severely damages the stability and consistency of roll forming.

[0003] The contradiction between lubrication and anti-slip has long remained unresolved in actual production. Operators often face a dilemma between "high wear and easy scratching" and "slippage and loss of control, unstable feeding." They either abandon lubrication, resulting in a significant reduction in the lifespan of rollers and profiles and drastic fluctuations in product quality, or they adopt inefficient solid lubrication or intermittent oil spraying to alleviate slippage. However, this forces the production line to reduce the roller speed to maintain basic stability, which directly restricts the processing efficiency and yield of embedded profiles, making it difficult to meet the urgent demand of high-speed railway tunnel projects for large quantities of high-quality embedded parts.

The hexagonal rod and the control tube are coaxially arranged.

[0006] Preferably, the lubrication mechanism further includes an internal spring disposed between the surfaces of the two telescopic tubes that are close to each other, and each telescopic tube is provided with an oil inlet groove, the two ends of which are connected to a plurality of diversion grooves and a transverse tube respectively.

[0007] Preferably, the lower ends of the plurality of adjustment frames are respectively provided with a plurality of drive shafts, and the plurality of drive shafts are respectively connected to drive components. Each drive shaft is respectively fixedly provided with a plurality of bottom rollers of different shapes, and the two adjacent surfaces inside the bottom rollers respectively abut against and adhere to the follower ball.

[0009] Preferably, each of the plurality of adjustment frames is provided with an adjustment component, and a pressure roller is provided between two symmetrical adjustment components, and the plurality of pressure rollers are respectively matched with the bottom roller at the lower end.

[0010] Preferably, the adjustment mechanism further includes a first one-way component and a second one-way component. One end of the first one-way component is connected to the side wall of the oil storage sleeve, and the other end of the first one-way component is connected to an external oil supply device. A second one-way component is provided on the end face of the oil storage sleeve away from the control pipe. One end of the second one-way component is connected to the inside of the oil storage sleeve, and the other end of the second one-way component is connected to the transverse pipe.

[0011] Preferably, the flow direction of the first unidirectional component is from the outside to the oil storage sleeve, and the flow direction of the second unidirectional component is from the oil storage sleeve to the horizontal pipe.

[0012] Preferably, a piston disc is slidably connected inside the oil storage sleeve, and multiple vent holes are opened on the adjacent surfaces of the oil storage sleeve and the control pipe. The piston disc is connected to the hexagonal rod, and a handle is provided at the end of the hexagonal rod, and a connecting groove is opened inside the hexagonal rod.

[0013] Preferably, a spring is provided on the threaded disc, and a push plate is provided at the connection between the hexagonal rod and the piston disc, with the spring abutting against the push plate.

[0014] This invention provides a high-efficiency roll forming method for pre-embedded profiles in high-speed railway tunnels, comprising the following steps: Step one is the plate positioning and preliminary rolling stage. The operator places the plate to be processed between the bottom roller and the pressure roller, starts the drive assembly to drive multiple drive shafts and the bottom roller to rotate, and at the same time adjusts the downward pressure of the pressure roller by adjusting the assembly, so that the plate gradually produces the predetermined deformation in multiple rolling stations to form the preliminary shape of the required profile. Step two is the lubrication and anti-slip sealing stage. During the high-speed rolling process, the lubricating oil in the transverse tube enters the distribution groove in the sleeve through the oil inlet groove, and evenly fills the oil outlet groove on the follower ball. When the follower ball rotates with the bottom roller, it applies the lubricating oil to the end face of the adjacent bottom roller. The lubricating oil is then carried to the upper part of the roller surface to contact the plate to reduce friction. At the same time, the plate is pressed down, causing the belt to be pressed into the belt groove. The belt elastically deforms and fits tightly with the groove wall to form a seal, preventing the lubricating oil from flowing to the drive surface and ensuring that the transmission friction between the belt and the belt groove is not affected. Step three is the oil supply pressure adjustment and continuous rolling stage. The operator adjusts the axial position of the threaded disc in the control tube by turning the handle, changes the initial compression of the spring to set the required oil supply pressure, and the lubricating oil in the oil storage sleeve enters the transverse tube through the second one-way component under the spring thrust to achieve quantitative oil supply. When the oil storage sleeve is emptied, the handle is pulled back to move the piston disc backward, and the first one-way component draws in the lubricating oil to complete the oil replenishment. Under continuous and stable lubrication and anti-slip conditions, the efficient rolling forming of the profile is completed.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a high-efficiency roll forming device and method for pre-embedded profiles in high-speed railway tunnels, which has the following beneficial effects: This invention achieves precise and continuous lubrication of the bottom roller end face through an innovative follower ball lubrication structure, fundamentally solving the problems of roller surface wear and profile scratches caused by excessive friction during high-speed rolling. The follower ball in the lubrication mechanism is always in contact with the end faces of the two adjacent bottom rollers under the preload of the internal spring and rotates synchronously with the bottom rollers. The oil outlet groove opened on the outer wall of the follower ball carries the lubricating oil supplied by the transverse tube to the contact area during rotation and evenly applies it to the end face of the bottom roller. The lubricating oil is then carried to the upper part of the roller surface and contacts the plate to form a friction-reducing oil film as the bottom roller rotates. This follower oiling method makes the supply of lubricating oil automatically synchronized with the rolling movement, and applies a quantitative amount only to the parts that need lubrication, avoiding the oil waste and pollution spread caused by the traditional overall application method.

[0016] The belt pressing and sealing structure constructed in this invention not only achieves effective lubrication but also completely eliminates the transmission slippage problem caused by the migration of lubricating oil to the drive surface. A belt is installed in the groove opened on each bottom roller. When the sheet is pressed into the roller gap, the weight of the sheet and the pressure of the roller cause the belt to be pressed into the groove. The elastic deformation of the belt makes it form a tight fit and seal with the groove wall, thereby effectively isolating the drive surface from the end face lubrication area and preventing lubricating oil from flowing from the end face of the bottom roller to the groove and drive surface area. This ensures that the friction between the belt and the groove remains stable, so that the profile always obtains reliable traction during high-speed rolling. This fundamentally solves the contradiction between "lubrication and slippage" in traditional technology.

[0017] The adjustment mechanism of this invention achieves stepless adjustment of oil supply pressure and automatic oil replenishment through the cooperation of spring preload and one-way valve. This allows the device to flexibly match the supply of lubricating oil according to different profiles and rolling speeds. The operator can change the initial compression of the spring by turning the handle to move the threaded disc axially within the control tube, thereby adjusting the thrust of the piston disc on the lubricating oil in the oil storage sleeve. The greater the thrust, the higher the oil supply pressure and the greater the oil output, and vice versa. This mechanical pressure adjustment method is intuitive, reliable, and requires no external energy. At the same time, the alternating opening and closing of the first and second one-way components allows the oil storage sleeve to be automatically replenished by pulling the handle backward after being emptied, ensuring the continuous oil supply capacity of the lubrication system and providing a stable guarantee for long-term continuous high-speed rolling production.

[0018] This invention integrates three major functions—lubrication, sealing, and oil supply regulation—into a compact roll forming device. It achieves synergistic optimization of lubrication and transmission during high-speed roll forming. The rolling contact between the follower ball and the bottom roller end face converts sliding friction into rolling friction, significantly reducing wear in the contact area. The belt-pressed sealing structure achieves dynamic sealing using the pressure of the plate itself without adding additional sealing elements. The spring-adjustable oil supply mechanism allows the operator to quickly adjust the oil volume according to actual working conditions. The synergistic effect of these three functions enables the device to achieve good surface quality and dimensional accuracy while maintaining high roll forming speed. The service life of both the rollers and the profiles is significantly extended, while production interruptions caused by slippage or wear are reduced. This provides reliable technical support for the mass, high-efficiency, and high-quality production of pre-embedded profiles for high-speed railway tunnels. Attached Figure Description

A push plate 313 is provided at the connection between the hexagonal rod 35 and the piston disc 38, and one end of the spring 312 abuts against the threaded disc 34 and the other end abuts against the push plate 313.

[0028] 3. Working process and principle of the device The working process and principle of the high-speed railway tunnel pre-embedded profile high-efficiency roll forming device are as follows: During profile roll forming, the sheet material to be processed is placed between the bottom roller 212 and the pressure roller 217. The drive assembly 12 is started to drive multiple drive shafts 211 and the bottom roller 212 to rotate. At the same time, the downward pressure of the pressure roller 217 is adjusted by the adjustment assembly 216 so that the sheet material gradually undergoes predetermined deformation in multiple roll forming stations, and finally forms the required profile. In order to reduce the friction between the bottom roller 212 and the sheet material during high-speed roll forming, lubricating oil needs to be applied to the adjacent end faces of the bottom rollers 212. The follower ball 26 in the lubrication mechanism 21 Under the preload of the internal spring 29, the ball 26 is always in contact with the end faces of the two adjacent bottom rollers 212. When the bottom roller 212 rotates, the follower ball 26 rotates accordingly. The lubricating oil with a certain pressure in the transverse tube 22 enters the diversion groove 28 in the sleeve 25 through the oil inlet groove 210, and then evenly fills the multiple oil outlet grooves 27 on the follower ball 26. When the follower ball 26 rotates, the lubricating oil in the oil outlet groove 27 is carried to the contact area between the follower ball 26 and the end face of the bottom roller 212 and applied to the end face of the bottom roller 212. The lubricating oil is then carried to the upper part of the roller surface and contacts the plate with the rotation of the bottom roller 212, thereby effectively reducing friction.

[0029] To prevent lubricating oil from flowing onto the drive surface 215 and affecting the transmission friction of the belt 214, a belt 214 is installed in the groove 213 on each bottom roller 212. When the sheet material is pressed onto the bottom roller 212, the belt 214 is pressed into the groove 213 by the sheet material. The elastic deformation of the belt 214 makes it fit tightly against the groove wall of the groove 213 to form a seal, thereby preventing lubricating oil from flowing from the end face of the bottom roller 212 to the drive surface 215 area, ensuring that the friction between the belt 214 and the groove 213 is not affected, and ensuring the traction stability of roll forming.

[0030] The regulating mechanism 31 is used to control the supply pressure of lubricating oil. Initially, the oil reservoir 32 is filled with lubricating oil. The spring force of the spring 312 pushes the push plate 313 and piston plate 38 forward, forcing the lubricating oil in the oil reservoir 32 into the transverse tube 22 via the second one-way component 37. The first one-way component 36 is in the closed state. The compression of the spring 312 determines the oil supply pressure. The operator turns the handle 310, causing the hexagonal rod 35 and threaded disc 34 to rotate. Because the threaded disc 34 is threadedly connected to the control tube 33, the axial position of the threaded disc 34 changes, thereby adjusting the oil supply pressure. The initial compression of the spring 312 increases the distance between the threaded disc 34 and the push disc 313, thus increasing the compression of the spring 312 and raising the oil supply pressure. Conversely, the oil supply pressure decreases. After the lubricating oil in the oil reservoir 32 is emptied, the operator pulls the handle 310 backward to move the piston disc 38 backward, generating a negative pressure in the oil reservoir 32. The first one-way component 36 opens to draw in external lubricating oil, and the second one-way component 37 closes to complete the oil replenishment. Throughout the process, the connecting groove 311 and the exhaust port 39 in the hexagonal rod 35 remain connected to the atmosphere, ensuring that there is no air pressure obstruction when the piston disc 38 moves.

[0031] Working principle summary: This invention achieves precise lubrication of the end face of the bottom roller 212 through the rotational coating of the follower ball 26 and the oil outlet groove 27 in the lubrication mechanism 21. The elastic fit and sealing of the belt 214 and the groove 213 effectively isolates the lubricating oil from contaminating the drive surface 215. The stepless adjustment of the oil supply pressure is achieved through the cooperation of the threaded disc 34 and the spring 312 in the adjustment mechanism 31. The three work together to ensure that the high-speed roll forming process is adequately lubricated while maintaining stable traction transmission, which significantly improves processing efficiency and product quality.

A method for efficient roll forming of pre-embedded profiles for high-speed railway tunnels, employing the efficient roll forming device for pre-embedded profiles for high-speed railway tunnels as described in any one of claims 1-9, characterized in that: Includes the following steps: Step 1 is the plate positioning and preliminary rolling stage. The operator places the plate to be processed between the bottom roller (212) and the pressure roller (217), starts the drive assembly (12) to drive multiple drive shafts (211) and the bottom roller (212) to rotate, and at the same time adjusts the downward pressure of the pressure roller (217) by adjusting the assembly (216) so that the plate gradually produces the predetermined deformation in multiple rolling stations to form the preliminary shape of the required profile. Step two is the lubrication and anti-slip sealing stage. During the high-speed rolling process, the lubricating oil in the transverse tube (22) enters the distribution groove (28) in the sleeve (25) through the oil inlet groove (210), and evenly fills the oil outlet groove (27) on the follower ball (26).
