Description

Technical Field

[0001] The invention belongs to the technical field of straightening production of aluminum profile steel, and in particular relates to a straightening device for producing aluminum profile steel for railway construction. Background Art

[0002] During railway construction, aluminum profiles are important building materials. Their straightness and surface quality have a vital impact on the safety and stability of the railway. However, due to various factors during production, transportation or storage, aluminum profiles often bend or deform to varying degrees. Therefore, straightening aluminum profiles is an essential step before railway construction.

[0003] Traditional aluminum profile straightening devices usually use fixed straightening speeds and straightening forces, and cannot be adaptively adjusted according to the actual curvature of the aluminum profile. As a result, during the straightening process, for aluminum profiles with larger curvatures, the straightening effect may not be ideal, requiring multiple straightening attempts or increased straightening force, thereby increasing production costs and time. For aluminum profiles with smaller curvatures, excessive straightening force may cause material damage or over-straightening. Summary of the Invention

The adjustment structure is connected to the adaptive transmission mechanism and the moving component through a first oil pipe, and the adaptive transmission mechanism is connected to the moving component through a second oil pipe. The adaptive transmission mechanism is also provided with a driving component.

[0051] In this embodiment, specifically, the adaptive transmission mechanism further includes: a roller 201, which is rotatably connected to the lower end of the sliding column 202; an oil chamber shell 203, which is arranged at one end of the surface bracket of the support platform 1, and one end of the sliding column 202 is slidably connected to the oil chamber shell 203, and one end of the oil pipe 205 is connected to the upper end of the oil chamber shell 203, and one end of the oil pipe 212 is connected to the lower end of the oil chamber shell 203; a spring 204, the upper end of which is fixedly arranged on the oil chamber shell 203 and the lower end of which is fixedly arranged on the lower end of the sliding column 202, and is used to reset the sliding column 202 through the rebound effect of the spring 204;

[0052] It should also be understood that a limit plate is provided in the middle of the oil chamber housing 1 203 for limiting one end of the piston of the slide column 1 202 . When one end of the piston of the slide column 1 202 moves upward, the hydraulic oil in the upper end of the oil chamber housing 1 203 is squeezed into the oil pipe 1 205 . At the same time, when the upper end of the slide column 1 202 moves upward, the hydraulic oil in the oil pipe 2 212 is simultaneously drawn into the lower end of the oil chamber housing 1 203 .

[0053] A sealing gasket is provided at the sliding portion between the sliding column 202 and the lower end of the oil chamber housing 203 to ensure the sealing of the interior of the oil chamber housing 203.

When the conical disk 1 209 approaches the conical disk 211, the conical surfaces of the conical disk 1 209 and the conical disk 211 squeeze the one end of the belt 1 217, thereby increasing the diameter of the one end of the belt 1 217.

[0056] The connecting column 208 is slidably connected to the rotating shaft 210, and a sealing gasket is provided at the sliding connection between the second sliding column 207 and the second oil chamber housing 206.

[0058] A sealing gasket is provided at the connection between the displacement slide 214 and the displacement oil chamber 213 to ensure the sealing of the displacement oil chamber 213;

[0059] In this embodiment, the driving components include: a power source 215, the base of which is slidably connected to a slide groove provided on the support platform 1; one end of the displacement slide 214 is fixedly arranged on the base of the power source 215; a pulley 1 216, which is fixedly arranged at the output end of the power source 215 and is used to drive the rotating shaft 210 on the conical disk 1 209 and the conical disk 211 to rotate via a belt 1 217;

[0060] Among them, a protective shell is provided on the outside of the driving component, and the upper cover of the protective shell is connected by bolts to facilitate subsequent disassembly and maintenance. A vent is provided on one side of the protective shell, and a filter is provided in the vent;

[0061] In this embodiment, specifically: the straightening structure further includes: a straightening roller 303, which is arranged on the straightening roller 304 and is used to cooperate with the straightening roller 304 to straighten the aluminum steel; a support frame 301, which is used to support the straightening roller 303, and the straightening roller 303 is rotatably connected to the support frame 301, and the central axis of the straightening roller 303 is slidably connected to the through groove provided on the support frame 1 surface; a threaded rod 302, the lower end of which is rotatably provided in a T-shaped groove provided on the upper end of the support frame 1 surface, and is used to drive the support frame 301 to rise and fall, and the threaded rod 302 is threadedly connected to the support frame 301;

[0062] In this embodiment, the transmission assembly includes:

[0063] Pulley 2 305 is fixedly arranged on the rotating shaft 210, and pulley 2 305 drives pulley 3 307 to rotate via belt 2 306;

[0064] Among them, there are four groups of straightening rollers 304. The straightening rollers 304 of the group close to the roller 201 are fixedly arranged on the rotating shaft 210, and the pulley 307 is fixedly arranged on the central axis of the group of straightening rollers 304 far away from the roller 201. The other two groups of straightening rollers 304 are arranged between the two groups of transmission straightening rollers 304 and are rotatably connected to the bracket on the surface of the support platform 1.

[0065] It should also be understood that there are five sets of straightening rollers 1 303 , all of which are rotatably connected to the support frame 301 , and that the straightening rollers 1 303 and the straightening rollers 2 304 are arranged in a trapezoidal shape;

[0066] Wherein, the transmission component is arranged in the protective shell.

[0067] Working principle or structural principle: When in use, first turn on the power source 215, the power source 215 drives the pulley 1 216 to rotate, the pulley 1 216 drives the conical disk 1 209 and the conical disk 2 211 to rotate through the belt 1 217, the conical disk 211 and the conical disk 1 209 drive the rotating shaft 210 to rotate on the bracket on the surface of the support platform 1, the rotating shaft 210 drives a group of straightening rollers 2 304 to rotate, and at the same time, the rotating shaft 210 drives the pulley 2 305 to rotate, the pulley 2 305 drives the belt 2 306 to rotate, the belt 2 306 drives the pulley 3 307 to rotate, and the pulley 3 307 drives another group of straightening rollers 2 304 to rotate on the bracket on the surface of the support platform 1, and at the same time, the rotating shaft 210 drives the connecting column 208 on the conical disk 1 209 to rotate at one end of the sliding column 207;

[0068] Then, according to the thickness of the aluminum profile, the threaded rod 302 is screwed and rotated on the upper end of the support platform 1. The threaded rod 302 drives the support frame 301 to rise and fall through the threaded connection. The support frame 301 drives the five sets of straightening rollers 1 303 to slide in the through grooves on the support platform 1. When the distance between the straightening roller 1 303 and the straightening roller 2 304 is adjusted according to the thickness of the aluminum profile, it is ready.

[0069] Then, the aluminum profile that needs to be straightened is placed on the bracket of the support platform 1, and then the aluminum profile is pushed to move. When one end of the aluminum profile is located on the first set of straightening rollers 1 303 and the second set of straightening rollers 304, the rotation of the second set of straightening rollers 304 drives the aluminum profile to be conveyed;

[0070] When the larger curved surface on the aluminum steel material contacts the roller 201, the curved surface causes the roller 201 to drive the slide column 1 202 to slide upward in the oil chamber shell 1 203 and compress the spring 204. The slide column 1 202 is connected to the oil chamber shell 1 203 via a piston, squeezing the hydraulic oil at the upper end of the oil chamber shell 1 203 into the oil pipe 1 205, and then into the oil chamber shell 2 206 through the oil pipe 1 205. The hydraulic oil then pushes the slide column 2 207 in the oil chamber shell 206 to one side.

[0071] Sliding post 207 pushes connecting post 208 to slide within rotating shaft 210. Connecting post 208 drives conical disc 1 209 to slide on the slide groove of rotating shaft 210. By reducing the distance between conical disc 1 209 and conical disc 211, one end of belt 1 217 is squeezed, making the diameter of one end of belt 1 217 larger than the diameter of one end of upper belt 1 217 of pulley 1 216, thereby reducing the transmission ratio of belt 1 217.

[0072] At the same time, when the piston end of the slide column 202 moves upward, the hydraulic oil in the displacement oil chamber 213 is pumped into the lower end of the oil chamber shell 1 203 through the oil pipe 212. When the hydraulic oil in the displacement oil chamber 213 is extracted, the hydraulic oil drives the piston end of the displacement slide column 214 to move to one side, and the displacement slide column 214 drives the power source 215 to move synchronously on the slide groove on the support platform 1, thereby adjusting the distance between the pulley 1 216 and the conical disk 2 211 when adjusting the diameter of one end of the belt 1 217, maintaining the transmission of the power source 215, thereby reducing the transmission speed when the curvature of the aluminum steel surface is large, ensuring that the straightening roller 1 303, the straightening roller 2 304 and the aluminum steel have sufficient contact time and force, thereby achieving effective straightening;

[0073] The rotating shaft 210 simultaneously drives the second pulley 305 to rotate, the second pulley 305 drives the second belt 306 to rotate, the second belt 306 drives the third pulley 307 to rotate, and the third pulley 307 drives another set of second straightening rollers 304 to rotate, thereby ensuring the continuous transmission of the aluminum steel. The trapezoidal arrangement of the first straightening roller 303 and the second straightening roller 304 causes the aluminum steel to be subjected to multi-point contact pressure when passing through, thereby generating a reverse bending moment to offset the original bending. The bottom of the first straightening roller 303 and the second straightening roller 304 are provided with a conical receiving hopper for discharging debris and impurities generated by the straightening of the aluminum steel.

[0074] When the curvature of the aluminum steel surface is small, the sliding column 202 is reset by the rebound effect of the spring 204, and the sliding column 202 is reset to the middle position of the oil chamber shell 203 by the limit plate in the oil chamber shell 203. The conical disk 1 209 is reset by the reset of the sliding column 202, and the power source 215 is reset on the slide groove on the support platform 1. The transmission ratio of the pulley 1 216 and the conical disk 2 211 and the conical disk 1 209 is restored to the initial state through the reset, thereby accelerating the transmission speed when the curvature of the aluminum steel surface is small, which not only improves production efficiency but also avoids material damage caused by excessive straightening.

[0075] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
