Description

Technical Field

[0001] This application relates to the field of profile bending equipment technology, and in particular to a profile bending roller machine. Background Technology

[0002] In daily life, escalators are often installed at staircases where people travel. For the convenience of use, the ends of the escalator are often curved to a certain extent according to the inclination angle of the staircase. The curve is usually formed by the profiles used to manufacture the escalator using a rolling mill.

[0003] Large-angle bends in profiles typically require specialized rolling mills. However, depending on the application scenario and the angle of inclination of the stairs, the degree of bending of the escalator varies. When processing escalators with different bends, different types of profile bends require multiple adjustments to the current rolling mill. It is impossible to quickly adjust and change the bending curvature, which can easily lead to waste of profiles and long-term manual adjustment operations. Summary of the Invention

[0004] In order to improve the convenience of using a profile bending roller mill, this application provides a profile bending roller mill.

[0005] This application provides a profile bending roller mill, which adopts the following technical solution: A profile bending roller mill includes a frame, a conveying device for transporting profiles mounted on the frame, and a bending device for processing the curvature of the profiles mounted on the frame. The bending device includes a main pressure roller rotatably connected to the frame. A second motor for controlling the rotation of the main pressure roller is mounted on the frame. A second hydraulic cylinder is mounted on the frame, and the output shaft of the second hydraulic cylinder is fixedly connected to a second mounting plate. A support plate is connected to the second mounting plate. A first sliding groove is formed on the support plate, and a sliding plate is slidably connected to the support plate through the first sliding groove. A rotating rod is rotatably mounted on the sliding plate, and a secondary pressure roller is mounted on the rotating rod. A lead screw is rotatably connected to the support plate, and a first slider is threaded onto the lead screw. A push rod is hinged to the first slider, and the end of the push rod away from the first slider is hinged to the sliding plate.

[0006] By adopting the above technical solution, the profile is transported to the processing position using a conveying device. The second hydraulic cylinder pushes the auxiliary pressure roller closer to the main pressure roller, the second motor controls the rotation of the main pressure roller, and the conveying device controls the rollers to rotate and transport the profile between the main and auxiliary pressure rollers. When the profile passes the auxiliary pressure roller, it enters between the auxiliary and main pressure rollers. The extrusion pressure between the auxiliary and main pressure rollers causes the profile to deform and bend, which can quickly process the bending arc of the profile. When it is necessary to change the processing arc, the screw is rotated to control the first slider to move. The first slider drives the push rod to control the slide plate to move away from or closer to the main pressure roller, thereby changing the distance between the auxiliary and main pressure rollers, thus changing the degree of bending of the profile by the auxiliary and main pressure rollers. This is beneficial for the profile bending roller to process and manufacture profiles with different degrees of bending, and improves the convenience of using the profile bending roller.

[0007] In one specific implementation scheme, the main pressure roller has a first pressure groove that is the same as the outline of the profile, and the auxiliary pressure roller has a second pressure groove that is the same as the outline of the profile.

[0008] By adopting the above technical solution, when the profile passes through the main pressure roller and the auxiliary pressure roller, it enters between the first pressure groove and the second pressure groove. The first pressure groove and the second pressure groove match the outer contour of the profile, which can protect the profile and ensure that the profile passes smoothly through the main pressure roller and the auxiliary pressure roller to complete the curvature processing.

[0009] In one specific implementation, the lead screw is divided into two sections, the two sections of the lead screw are provided with threads of opposite directions, and the first slider is threadedly connected to both sections of the lead screw.

[0010] By adopting the above technical solution, setting a reverse thread on the lead screw, and installing two first sliders to simultaneously control the movement of the slide and support the slide, it is beneficial to improve the stability of the slide and increase its stability.

[0011] In one specific implementation, the conveying device includes a first mounting frame, which is mounted on the frame. A first hydraulic cylinder is mounted on the first mounting frame, and the output shaft of the first hydraulic cylinder is fixedly connected to a first mounting plate. A set of transmission rollers is mounted on the first mounting plate. Each set of transmission rollers includes two rollers, which are vertically arranged in an up-down relationship. A first motor for controlling the rotation of the rollers is mounted on the first mounting plate.

[0012] By adopting the above technical solution, the profile is passed through the rollers, and the first motor controls the rotation of the rollers. The two rollers squeeze and transport the profile, which enables the profile to reach the processing position smoothly, which helps to improve the efficiency of the profile bending roller machine during use.

[0013] In one specific implementation scheme, a positioning component for positioning the profile is connected to the first mounting plate. The positioning component includes a connecting plate connected to the first mounting plate. The connecting plate has a sixth sliding groove and a fifth guide rod installed on it. The fifth guide rod is disposed within the sixth sliding groove, and a sixth slider is slidably mounted on the fifth guide rod. A third spring is sleeved on the guide rod, with one end connected to the sixth slider and the other end connected to the connecting plate. A positioning plate for positioning the profile is installed on the sixth slider. The positioning plate has a seventh sliding groove, through which the seventh slider is slidably mounted. A third mounting plate is mounted on the frame, and a fixing rod is mounted on it. A third pull rod is hinged to the fixing rod, with the end of the third pull rod away from the fixing rod hinged to the seventh slider.

[0014] By adopting the above technical solution, when transporting the profile, the conveying stops when the profile comes into contact with the positioning plate. The positioning plate positions the profile, which can quickly determine the length of the arc to be processed. After positioning, the connecting plate moves the positioning plate away from the fixed rod. The third pull rod rotates around the fixed rod, which moves the seventh slider at the bottom of the seventh slide, thereby pulling the positioning plate downward. When the profile reaches the processing position, the positioning plate moves below the profile to release it, which facilitates the rapid release of the profile and allows it to continue to move and be processed.

[0015] In one specific implementation scheme, the connecting plate has a second sliding groove, and a first guide rod is installed on the connecting plate. The first guide rod is disposed within the second sliding groove, and a second slider is slidably connected to the first guide rod. A first spring is sleeved on the first guide rod, with one end of the first spring connected to the second slider and the other end connected to the connecting plate. A first clamping plate is installed on the second slider, and a limiting plate is installed on the connecting plate to limit the displacement distance of the first clamping plate. A loading block is connected to the third mounting plate, and a fifth sliding groove is opened on the loading block. A fourth guide rod is installed on the loading block, disposed within the fifth sliding groove, and a fifth slider is slidably connected to the fourth guide rod. A second spring is sleeved on the fourth guide rod, with one end of the second spring connected to the fifth slider and the other end connected to the loading block. A second clamping plate is installed on the fifth slider.

[0016] By adopting the above technical solution, when the first mounting plate moves the connecting plate, the first clamping plate approaches the second clamping plate to clamp the profile. When the profile continues to be transported and processed, because the first clamping plate and the second clamping plate are in a holding state, the profile moves and drives the first clamping plate and the second slider to slide on the connecting plate. The second clamping plate and the fifth slider slide on the loading block, so that the first clamping plate and the second clamping plate always hold the profile tightly, separating the end of the profile with the arc shape to be processed from the end without the arc shape. By clamping the profile with the first clamping plate and the second clamping plate, the profile is kept in a straight state, reducing the impact on the profile transported behind when processing the arc shape. When the first clamping plate and the second clamping plate follow the profile to abut against the limiting plate, the continued movement of the profile is restricted, preventing the arc processing length from being too long.

[0017] In one specific implementation scheme, the first clamping plate and the second clamping plate are configured as arc-shaped plates, and the curvature of the arc-shaped plates is the same as the curvature of the profile outline.

[0018] By adopting the above technical solution, the first and second clamping plates are set as arc-shaped plates, which can better fit with the profile and clamp the profile, thereby improving the clamping degree of the first and second clamping plates on the profile.

[0019] In one specific implementation scheme, a third sliding groove is formed on the third mounting plate, a second guide rod is mounted on the third mounting plate, the second guide rod is disposed within the third sliding groove, a third slider is slidably connected to the second guide rod, and the third slider is connected to the connecting plate; a fourth sliding groove is formed on the third mounting plate, a third guide rod is mounted on the third mounting plate, the third guide rod is disposed within the fourth sliding groove, a fourth slider is slidably connected to the third guide rod, and the fourth slider is connected to the loading block; a rotating bar is rotatably mounted on the third mounting plate, the rotating bar is disposed between the third slider and the fourth slider, one end of the rotating bar is hinged to a first pull rod, the end of the first pull rod away from the rotating bar is connected to the third slider, and the other end of the rotating bar is hinged to a second pull rod, the end of the second pull rod away from the rotating bar is hinged to the fourth slider.

[0020] By adopting the above technical solution, the connecting plate drives the third slider to move closer to the fourth slider. The third slider pushes the first pull rod to make the rotating bar rotate. When the rotating bar rotates, the other end pulls the second pull rod to move. The second pull rod pulls the fourth slider to slide closer to the third slider on the third mounting plate, so that the second clamping plate becomes a movable clamping plate. When the first clamping plate approaches the second clamping plate, the second clamping plate also moves closer to the first clamping plate, making it easier for the profile to be clamped. This allows the first clamping plate and the second clamping plate to come together and quickly clamp and fix the profile.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The profile is transported to the processing position using a conveying device. The second hydraulic cylinder pushes the auxiliary pressure roller closer to the main pressure roller, the second motor controls the rotation of the main pressure roller, and the conveying device controls the rollers to rotate and transport the profile between the main and auxiliary pressure rollers. When the profile passes the auxiliary pressure roller, it enters between the auxiliary and main pressure rollers. The extrusion pressure between the auxiliary and main pressure rollers causes the profile to deform and bend, which can quickly process the bending arc of the profile. When it is necessary to change the processing arc, the screw is rotated to control the first slider to move. The first slider drives the push rod to control the slide plate to move away from or closer to the main pressure roller, thereby changing the distance between the auxiliary and main pressure rollers, thus changing the degree of bending of the profile under the extrusion pressure of the auxiliary and main pressure rollers. This is beneficial for the profile bending roller to process and manufacture profiles with different degrees of bending, and improves the convenience of using the profile bending roller.

[0022] 2. When transporting profiles, the conveying stops when the profile comes into contact with the positioning plate. The positioning plate positions the profile, which can quickly determine the length of the arc to be processed. After positioning, the connecting plate moves the positioning plate away from the fixed rod. The third pull rod rotates around the fixed rod, which moves the seventh slider at the bottom of the seventh slide, thereby pulling the positioning plate downward. When the profile reaches the processing position, the positioning plate moves below the profile to release it, which facilitates the rapid release of the profile and allows it to continue moving and being processed.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] Example: This application discloses a profile bending roller mill, referring to... Figure 1 It includes a frame 1, a conveying device 2 for transporting profiles installed on the frame 1, a positioning component 3 for positioning the profiles connected to the conveying device 2, and a bending device 4 for processing and bending the profiles installed on the frame 1.

[0033] The profile is transported to the processing position by the conveying device 2, and the profile is positioned by the positioning component 3 to determine the length of the arc to be processed. After positioning, the profile is processed by the bending device 4 to make the profile present an arc, which facilitates the rapid processing of the profile and improves the convenience of using the profile bending roller machine.

[0034] Reference Figure 1 and Figure 2The conveying device 2 includes a first mounting frame 21, which is fixedly mounted on the frame 1. A first hydraulic cylinder 22 is fixedly mounted on the first mounting frame 21. The output shaft of the first hydraulic cylinder 22 is fixedly connected to a first mounting plate 23. Three sets of transmission roller groups 24 are rotatably mounted on the first mounting plate 23. The three sets of transmission roller groups 24 are equidistantly arranged. Each set of transmission roller groups 24 includes two rollers 241, which are vertically arranged in an up-down relationship. Each roller 241 has a transport groove 2411 with the same shape as the profile. The upper and lower rollers 241 are connected by a synchronous pulley and a synchronous belt, respectively.

[0035] The profile is placed in the transport groove 2411 of the roller 241, and the profile is squeezed and transported by the rollers 241 on the upper and lower sides. The profile is positioned in the transport groove 2411 and prevented from falling off the roller 241 during the transport process, so that the profile has stability during the transport process.

[0036] Reference Figure 3 and Figure 4 The positioning component 3 includes a connecting plate 31, which is fixedly connected to the first mounting plate 23. A second sliding groove 311 is provided on the connecting plate 31. A first guide rod 312 is fixedly installed on the connecting plate 31 and is disposed in the second sliding groove 311.

A fourth sliding groove 324 is formed on the third mounting plate 32, located on the side of the third sliding groove 321 near the bending device 4. A third guide rod 325 is fixedly mounted on the third mounting plate 32, positioned within the fourth sliding groove 324. A fourth slider 326 is slidably mounted on the third guide rod 325. A rotating bar 341 is rotatably mounted on the third mounting plate 32. The center of the rotating bar 341 is rotatably connected to the third mounting plate 32. The rotating bar 341 is positioned between the third slider 323 and the fourth slider 326. A first pull rod 342 is hinged to the end of the rotating bar 341 near the connecting plate 31. The end of the first pull rod 342 away from the rotating bar 341 is hinged to the third slider 323. A second pull rod 343 is hinged to the end of the rotating bar 341 away from the connecting plate 31. The end of the second pull rod 343 away from the rotating bar 341 is hinged to the fourth slider 326.

[0038] A loading block 33 is fixedly installed on the fourth slider 326. A fifth sliding groove 331 is provided on the loading block 33. A fourth guide rod 332 is fixedly installed on the loading block 33. The fourth guide rod 332 is disposed in the fifth sliding groove 331. A fifth slider 333 is slidably installed on the fourth guide rod 332. A second spring 334 is sleeved on the fourth guide rod 332. One end of the second spring 334 is fixedly connected to the fifth slider 333, and the other end is fixedly connected to the loading block 33. A second clamping plate 335 is fixedly installed on the fifth slider 333. In this embodiment, the first clamping plate 315 and the second clamping plate 335 are set as arc-shaped plates and the curvature is the same as the curvature of the profile outline.

[0039] Reference Figure 4 and Figure 5The connecting plate 31 has a sixth sliding groove 351. A fifth guide rod 352 is fixedly installed on the connecting plate 31. The fifth guide rod 352 is vertically set in the sixth sliding groove 351. A sixth slider 353 is slidably installed on the fifth guide rod 352. A third spring 354 is sleeved on the fifth guide rod 352. One end of the third spring 354 is fixedly connected to the sixth slider 353, and the other end is fixedly connected to the connecting plate 31. A positioning plate 355 is fixedly connected to the sixth slider 353. A seventh slide groove 3551 is provided on the positioning plate 355. The seventh slide groove 3551 is located on the side of the connecting plate 31 near the third slider 323. A seventh slider 356 is slidably connected to the positioning plate 355 through the seventh slide groove 3551. A fixing rod 357 is fixedly installed on the third mounting plate 32. The fixing rod 357 is located on the side of the connecting plate 31 away from the second clamping plate 335. A third pull rod 358 is hinged to the fixing rod 357. The end of the third pull rod 358 away from the fixing rod 357 is hinged to the seventh slider 356.

[0040] Reference Figure 3 and Figure 5 The positioning plate 355 is raised to the top of the sixth slide groove 351 by the support of the sixth slider 353 by the third spring 354. At this time, the seventh slider 356 is at the bottom of the seventh slide groove 3551. When transporting the profile, the profile passes between the first clamping plate 315 and the second clamping plate 335 and stops transporting when it finally comes into contact with the positioning plate 355. The positioning plate 355 positions the profile, which can quickly determine the length of the arc of the profile processing.

[0041] Reference Figure 1 , Figure 3 and Figure 4 After positioning, the first hydraulic cylinder 22 pushes the first mounting plate 23 to bring the profile closer to the bending device 4. The first mounting plate 23 drives the connecting plate 31 to move. The connecting plate 31 drives the third slider 323 to move closer to the fourth slider 326. The third slider 323 pushes the first pull rod 342 to make the rotating bar 341 rotate. When the rotating bar 341 rotates, the other end pulls the second pull rod 343 to move. The second pull rod 343 pulls the fourth slider 326 to slide on the third mounting plate 32 towards the third slider 323, so that the first clamping plate 315 and the second clamping plate 335 come together and clamp and fix the profile.

[0042] Reference Figure 3 , Figure 4 and Figure 5While the first clamping plate 315 and the second clamping plate 335 come together to clamp the profile, the connecting plate 31 drives the positioning plate 355 to move away from the fixed rod 357. The third pull rod 358 rotates around the fixed rod 357, driving the seventh slider 356 located at the bottom of the seventh slide groove 3551 to move, thereby pulling the positioning plate 355 downward. When the profile reaches the processing position, the positioning plate 355 moves below the profile to release the profile.

[0043] During the processing of the profile, the profile continues to be transported. Because the positioning plate 355 is located below the profile, the profile moves above the positioning plate 355 during transport. At this time, because the first clamping plate 315 and the second clamping plate 335 are in a holding state for the profile, the profile moves and drives the first clamping plate 315 and the second slider 313 to slide on the connecting plate 31, while the second clamping plate 335 and the fifth slider 333 slide on the loading block 33. This ensures that the first clamping plate 315 and the second clamping plate 335 always hold the profile tightly, separating the end of the profile with the arc shape that does not need to be processed from the end with the arc shape. By clamping the profile with the first clamping plate 315 and the second clamping plate 335, the profile is kept in a straight state, reducing the impact of processing the arc shape on the profile transported behind. When the first clamping plate 315 and the second clamping plate 335 follow the profile to abut against the limiting plate 316, the continued movement of the profile is restricted to prevent the arc processing length from being too long.

[0044] After the profile is processed into an arc shape, the first hydraulic cylinder 22 pulls the first mounting plate 23 to move the profile away from the processing position. The first mounting plate 23 drives the connecting plate 31 to move. The connecting plate 31 drives the third slider 323 to move away from the second clamping plate 335. The third slider 323 pulls the rotating bar 341 to rotate. The rotating bar 341 pushes the fourth slider 326 to move the second clamping plate 335 away from the first clamping plate 315 to unlock the profile. Simultaneously, the connecting plate 31 will drive the third pull rod 358 to move. The third pull rod 358 rotates around the fixed rod 357. The third pull rod 358 pushes the seventh slider 356 to slide on the positioning plate 355. When the connecting plate 31 returns to the initial position with the first mounting plate 23, the third pull rod 358 pushes the seventh slider 356 to slide to the top of the seventh slide groove 3551. Because the profile has not yet been removed from the connecting plate 31, the positioning plate 355 is still below the profile due to the obstruction of the profile. After the profile is removed, the third spring 354 pushes the sixth slider 353 to slide upward on the fifth guide rod 352, thereby driving the positioning plate 355 to slide upward to prepare to block and position the next profile. When the positioning plate 355 slides upward, the third pull rod 358 and the seventh slider 356 remain stationary. When the positioning plate 355 returns to the initial position, the seventh slider 356 moves back to the bottom of the seventh slide groove 3551.

[0045] Reference Figure 6 and Figure 7The bending device 4 includes a rotating shaft 41, which is rotatably mounted on a frame 1. A second motor 42, which controls the rotation of the rotating shaft 41, is fixedly mounted on the frame 1. A main pressure roller 43 is fixedly mounted on the rotating shaft 41, and a first pressure groove 431 with the same outline as the profile is formed on the main pressure roller 43. A second hydraulic cylinder 44 is mounted on the frame 1. The output shaft of the second hydraulic cylinder 44 is fixedly connected to a second mounting plate 45. A support plate 451 is fixedly mounted on the second mounting plate 45. A first sliding groove 4511 is formed on the support plate 451. A sliding plate 452 is slidably mounted on the support plate 451 through the first sliding groove 4511. A rotating rod 453 is rotatably mounted on the sliding plate 452. A secondary pressure roller 454 is fixedly mounted on the rotating rod 453, and a second pressure groove 4541 with the same outline as the profile is formed on the secondary pressure roller 454. A lead screw 455 is rotatably mounted on the support plate 451. The lead screw 455 is divided into two sections in the middle. The two sections of the lead screw 455 are set with threads in opposite directions. A first slider 456 is threadedly connected to different sections of the lead screw 455. A push rod 457 is hinged to the first slider 456. The end of the push rod 457 away from the first slider 456 is hinged to the slide plate 452.

[0046] Once the profile is positioned, the second hydraulic cylinder 44 pushes the auxiliary pressure roller 454 closer to the main pressure roller 43, causing the side of the auxiliary pressure roller 454 closest to the main pressure roller 43 to protrude from the profile's transport path. The second motor 42 controls the rotating shaft 41 to rotate, which in turn drives the main pressure roller 43 to rotate. At this time, the first motor 242 continues to control the roller 241 to rotate, transporting the profile between the main pressure roller 43 and the auxiliary pressure roller 454. When passing the auxiliary pressure roller 454, the profile enters the second pressure groove 4541 of the auxiliary pressure roller 454 and the first pressure groove 431 of the main pressure roller 43. The profile is deformed and bent by the squeezing force between the auxiliary pressure roller 454 and the main pressure roller 43.

[0047] When it is necessary to change the curvature of the profile, the screw 455 is rotated to control the two first sliders 456 on the screw 455 to move closer or further apart; when it is necessary to increase the curvature of the profile, the first slider 456 pulls the push rod 457 to drive the slide plate 452 to move away from the main pressure roller 43 on the support plate 451. When the second hydraulic cylinder 44 pushes the auxiliary pressure roller 454 closer to the main pressure roller 43, the distance between the auxiliary pressure roller 454 and the main pressure roller 43 will increase, thereby reducing the degree of compression of the profile by the auxiliary pressure roller 454 and the main pressure roller 43, and reducing the curvature of the profile. When it is necessary to reduce the curvature of the profile, the first slider 456 pushes the push rod 457 to move the slide plate 452 on the support plate 451 toward the main pressure roller 43. When the second hydraulic cylinder 44 pushes the auxiliary pressure roller 454 toward the main pressure roller 43, the distance between the auxiliary pressure roller 454 and the main pressure roller 43 will decrease, thereby increasing the degree of compression of the profile by the auxiliary pressure roller 454 and the main pressure roller 43, and increasing the curvature of the profile.

[0048] The implementation principle of this application embodiment is as follows: The profile is transported to the processing position via the conveying device 2. During the transport, the profile passes between the first clamping plate 315 and the second clamping plate 335, and the conveying stops when it finally comes into contact with the positioning plate 355. The positioning plate 355 positions the profile, which can quickly determine the length of the arc to be processed. After positioning, the first clamping plate 315 and the second clamping plate 335 move closer together and clamp the profile. While the first clamping plate 315 and the second clamping plate 335 move closer together to clamp the profile, the positioning plate 355 moves downward. When the profile reaches the processing position, the positioning plate 355 moves below the profile to release it. When the profile approaches the main pressure roller 43, the bending device 4 processes the profile to make it bend, which facilitates rapid processing of the profile and improves the convenience of using the profile bending roller machine.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
