Description
Technical Field
[0001] This invention belongs to the field of elevator guide rail assembly cutting and processing, and particularly relates to an automatic cutting device for elevator guide rail assemblies. Background Technology
[0002] The elevator guide rail assembly is a crucial component of the elevator system, responsible for guiding the vertical movement of the elevator car and counterweight, ensuring smooth operation. The elevator guide rail assembly mainly consists of guide rails, guide rail supports, and guide shoes.
[0003] In electric propulsion guide rail assemblies, the angle iron inside the guide rail bracket is used to fix the guide rail to the building. When processing it, a long strip of steel is usually bent into shape, and then its surface is punched at predetermined intervals to form mounting holes. Then the whole section is cut to form an angle iron blank.
[0004] Currently, the automatic cutting of angle iron on guide rail brackets has the following defects: 1. After the long steel strip is bent into an L-shape, punching and cutting are carried out on different equipment. The steel needs to be loaded and unloaded at each step, and a lot of time is wasted when transferring it from one step to the next, so the efficiency needs to be improved; 2. When performing continuous whole-section cutting, the steel is generally conveyed by conveyor rollers at the same time. When cutting after reaching the designated position, since the lower part of the steel is supported by the conveyor rollers, conventional positioning devices have difficulty in effectively positioning the steel, thus affecting the cutting quality of the steel.

[0034] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.
[0035] Please see Figure 1An automatic cutting device for elevator guide rail components includes a frame 1, a conveying mechanism 2 on the upper part of the frame 1, a punching mechanism 3 on the upper front side and near the right side of the frame 1, a leveling mechanism 4 on the upper part of the frame 1 behind the punching mechanism 3, a first sliding mechanism 5 on the upper left side of the frame 1 near the punching mechanism 3, a horizontal plate 6 fixedly installed on the lower part of the frame 1, a second sliding mechanism 7 on the upper part of the horizontal plate 6 near the punching mechanism 3, a fixing mechanism 8 connected to both the first sliding mechanism 5 and the second sliding mechanism 7, and a driving mechanism 9 shared between the first sliding mechanism 5 and the second sliding mechanism 7, and a laser cutter 10 on the right side of the frame 1 near the punching mechanism 3. Angle iron 24, bent into an L-shape, is placed on conveying mechanism 2. One end of angle iron 24 passes through straightening mechanism 4, allowing angle iron 24 to be stably conveyed on conveying mechanism 2. When it is conveyed to punching mechanism 3, angle iron 24 is further positioned and fixed by first sliding mechanism 5 and second sliding mechanism 7 in conjunction with their respective fixing mechanisms 8. Then, punching and cutting are performed by punching mechanism 3 and laser cutter 10.
[0036] See Figure 1 and Figure 8 The conveying mechanism 2 includes multiple conveying rollers 201 rotatably mounted on the upper rear side of the frame 1 and multiple guide rollers 202 rotatably mounted on the upper front side of the frame 1. Any common end of any two adjacent conveying rollers 201 is connected via a first pulley system. A first motor 203 is fixedly mounted on the upper right side of the frame 1, and the output shaft of the first motor 203 is fixedly connected to the right end of the foremost conveying roller 201. The first motor 203 drives the conveying rollers 201 to rotate, thereby causing all conveying rollers 201 to rotate synchronously to convey the angle iron 24. When the angle iron 24 is conveyed to the vicinity of the punching mechanism 3, the guide rollers 202 support the angle iron 24.
[0037] See Figure 1 , Figure 4 , Figure 8 and Figure 9The straightening mechanism 4 includes two front and rear slide rails 401 fixedly mounted on the upper part of the horizontal plate 6. A screw 402 is rotatably mounted on the upper part of the slide rail 401. The screw 402 has two threaded sections with opposite thread directions, and each threaded section is threadedly connected to a slider 403. A first limiting plate 404 is fixedly connected between the two sliders 403 on the left side. An adjusting component 405 is mounted on each of the two sliders 403 on the right side. A second limiting plate 406 with an L-shaped structure is connected to the two adjusting components 405. Multiple left and right rotatably mounted limiting rollers 407 are mounted on the vertical and horizontal sections of the second limiting plate 406 and on the side wall of the first limiting plate 404. The right ends of the two screws 402 are connected by a sprocket set. A second motor 408 is fixedly mounted on the left end of any slide rail 401. The output shaft of the second motor 408 is fixedly connected to the left end of the corresponding screw 402. The adjustment assembly 405 includes a first connecting post 4051 whose lower end is fixedly connected to the corresponding slider 403 on the right side, a second connecting post 4052 whose upper end is threadedly connected to the first connecting post 4051, and a third connecting post 4053 with an L-shaped structure whose upper end is rotatably connected to the second connecting post 4052. The third connecting post 4053 is fixedly connected to the second limiting plate 406.
[0038] To facilitate stable feeding of the angle iron 24, the screw 402 is driven to rotate by the second motor 408, allowing the left and right sliders 403 to move closer or further apart. This allows the first limiting plate 404 and the second limiting plate 406 to move closer or further apart to adjust their spacing. This ensures that the limiting rollers 407 on the first limiting plate 404 and the vertical section of the second limiting plate 406 can respectively abut against the left and right sidewalls of the vertical section of the angle iron 24. Simultaneously, the two second connecting columns 4052 are rotated, changing the distance between the first connecting column 4051 and the third connecting column 4053. This changes the height of the second limiting plate 406, allowing the limiting rollers 407 on the horizontal section of the second limiting plate 406 to abut against the upper part of the horizontal section of the angle iron 24. This positions the angle iron 24 on the frame 1 according to a predetermined posture, and it is then conveyed by the conveying mechanism 2.
[0039] See Figure 1 , Figure 5 , Figure 7 and Figure 10The punching mechanism 3 includes an L-shaped mounting plate 301 fixedly mounted on the upper right side of the frame 1. Hydraulic rods 302 are fixedly mounted on the left side of the vertical section and the upper part of the horizontal section of the mounting plate 301. The output shaft of the hydraulic rods 302 is fixedly connected to two symmetrically arranged punching cutters 303. Push rods 25 are fixedly mounted on the upper right side of the frame 1, on both the front and rear sides of the mounting plate 301. The left end of the push rod 25 has a frustum-shaped structure. A movable hole 3031 is opened at the center of the punching cutter 303, and the movable hole 3031 is concentric with the corresponding push rod 25. An inclined receiving plate 26 is fixedly mounted on the upper part of the horizontal plate 6, below the punching cutter 303.
[0040] To facilitate the discharge of waste material after punching, the angle iron steel 24 is positioned by the fixing mechanism 8, and the corresponding punching cutter 303 is driven by the hydraulic rod 302 on the right side of the frame 1 to move towards the surface of the vertical section of the angle iron steel 24 and finally come into contact with it. The punching cutter 303 can cut off the corresponding part of the angle iron steel 24, and the waste material of the cut-off part is trapped inside the punching cutter 303. Then the hydraulic rod 302 on the right side retracts, driving the punching cutter 303 to reset. During the reset process of the punching cutter 303, the movable hole 3031 at the center of its interior will be inserted into the corresponding push rod 25, so that the push rod 25 is inserted into the interior of the punching cutter 303. As the punching cutter 303 moves, the push rod 25 can push out the waste material inside the punching cutter 303. After the waste material is pushed out, it falls onto the receiving plate 26 below and is discharged. Then the hydraulic rod 302 located above the center of the frame 1 is activated, moving the corresponding punching tool 303 toward the surface of the horizontal section of the angle iron steel 24 and finally contacting it. The punching tool 303 can cut off the corresponding part on the angle iron steel 24, and the cut-off waste material automatically falls onto the receiving plate 26 below under the action of gravity and is discharged.
[0041] See Figure 1 , Figure 4 , Figure 11 and Figure 12 The fixing mechanism 8 includes a U-shaped connecting frame 801. The front and rear pin ends of the connecting frame 801 are respectively fixedly provided with a positioning component 802 and a support base 803. The positioning component 802 includes a connecting plate 8021 fixedly connected to the pin ends of the connecting frame 801. Two sleeves 8022 are fixedly provided on the side of the connecting plate 8021 near the angle iron 24. A first spring 8023 is fixedly provided inside the sleeve 8022. A positioning post 8024 matching the end face of the punching tool 303 is fixedly connected to one end of the first spring 8023 near the port of the sleeve 8022. The positioning post 8024 is slidably provided inside the sleeve 8022. The surface of the support base 803 is provided with a through hole 8031 that is symmetrical and matches the end face of the punching tool 303. A limit stop 11 is fixedly provided on the front side of the connecting frame 801 near the second sliding mechanism 7.
[0042] To improve the stability of the angle iron 24 during processing, the angle iron 24 moves towards the limiting stop 11 via the conveying mechanism 2 and comes into contact with it. At this point, the angle iron 24 is in position, and then the first sliding mechanism 5 and the second sliding mechanism 7 are driven by the driving mechanism 9 to move. This allows the fixing mechanisms 8 on the first sliding mechanism 5 and the second sliding mechanism 7 to move towards the angle iron 24. The two positioning posts 8024 on the fixing mechanism 8 can be inserted into the two mounting holes that have been opened on the side wall of the angle iron 24. After the four positioning posts 8024 on the two fixing mechanisms 8 are simultaneously inserted into the corresponding mounting holes, the angle iron 24 can be positioned in the front-back direction. In addition, the support seat 803 on the fixing mechanism 8 can also be synchronously attached to the preset punching position on the surface of the angle iron 24. When the punching tool 303 on the punching mechanism 3 moves to this position, the support seat 803 can support the angle iron 24 from the other side, improving the quality of punching.
[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 7 The first sliding mechanism 5 includes two first toothed plates 501 that are slidably disposed on the upper left side of the frame 1 and are symmetrical front and back. The two first toothed plates 501 are fixedly connected to the connecting frame 801 on the corresponding fixing mechanism 8. A first rotating shaft 502 is rotatably disposed on the upper left side of the frame 1 above the first toothed plates 501. Two first gears 503 are fixedly disposed on the first rotating shaft 502. The two first gears 503 respectively mesh with the corresponding first toothed plates 501 below. A first worm gear assembly 504 is disposed at the front end of the first rotating shaft 502. A first groove is provided on the first toothed plate 501 located on the rear side. A first electromagnet 12 is fixedly installed in the first groove. A first limiting block 13 is slidably installed on the upper left side of the frame 1 near the first electromagnet 12. The first limiting block 13 is in slidable contact with the first groove. A guide sleeve 14 is slidably fitted on the surface of the first limiting block 13. The guide sleeve 14 is fixedly installed on the upper part of the frame 1. A second spring 15 is fixedly connected to the front side of the first limiting block 13. The end of the second spring 15 away from the first limiting block 13 is fixedly connected to the upper part of the frame 1.
[0044] The first worm gear assembly 504 is driven to rotate by the drive mechanism 9, which in turn drives the first shaft 502 to rotate the two first gears 503. The rotation of the two first gears 503 causes the corresponding first toothed plate 501 to move. The movement of the first toothed plate 501 causes the fixing mechanism 8 located on the left side of the angle iron 24 to contact and position itself with the angle iron 24. At the same time, after the first toothed plate 501 moves into position, the first slide groove is aligned with the first limiting block 13. The first electromagnet 12 is energized, attracting the first limiting block 13 and moving it into the first slide groove. Thus, the first limiting block 13 is inserted into the first slide groove, limiting and locking the first toothed plate 501. When the punching mechanism 3 applies pressure to the support base 803, the first toothed plate 501 will be pushed by the support base 801. Since the first toothed plate 501 is locked, it will not move at this time. When the first toothed plate 501 needs to move, the first electromagnet 12 is de-energized, causing the first limiting block 13 to reset under the action of the second spring 15, thus releasing the limitation on the first toothed plate 501.
[0045] See Figure 2 and Figure 7 The drive mechanism 9 includes a third motor 901 fixedly mounted on the front side of the frame 1. The third motor 901 is a dual-axis motor, and its left output shaft is connected to the worm in the first worm gear assembly 504 via a second pulley assembly 902. The forward rotation of the third motor 901, in conjunction with the second pulley assembly 902, drives the first worm gear assembly 504 to rotate, thus driving the first rotating shaft 502 to rotate.
[0046] See Figure 1 , Figure 5 , Figure 6 and Figure 7The second sliding mechanism 7 includes a vertical plate 701 fixedly mounted on the horizontal plate 6. A second rotating shaft 702 is rotatably mounted on the vertical plate 701. A second gear 703 is fixedly mounted at the rear end of the second rotating shaft 702. A second toothed plate 706 meshes with the second gear 703. The second toothed plate 706 is fixedly connected to the horizontal section of the corresponding connecting frame 801. Guide posts 704 are fixedly mounted on both the front and rear sides of the second toothed plate 706 on the upper part of the horizontal plate 6. The guide posts 704 are slidably connected to the horizontal section of the corresponding connecting frame 801. A second worm gear assembly 705 is mounted at the front end of the second rotating shaft 702. The right output shaft of the third motor 901 is fixedly connected to the worm in the second worm gear assembly 705. A guide groove is provided on the left side wall of the second toothed plate 706. A guide plate 16 is slidably connected in the guide groove. The lower end of the guide plate 16 is fixedly connected to the upper part of the horizontal plate 6. A second sliding groove is provided in the front side of the guide plate 16 near the lower part. A third spring 17 is fixedly installed in the second sliding groove. A second iron limiting block 18 is fixedly connected to one end of the third spring 17 near the port of the second sliding groove. The second limiting block 18 is slidably installed in the second sliding groove and is in movable contact with the lower surface of the second toothed plate 706. A movable cavity communicating with the second sliding groove is provided inside the guide plate 16. A second electromagnet 19 is fixedly installed in the movable cavity.
[0047] The third motor 901 drives the second worm gear assembly 705 to rotate, causing the second shaft 702 to rotate. This, in turn, rotates the second gear 703, causing the second toothed plate 706 to move towards the corresponding fixing mechanism 8 and make contact with the angle iron 24 for positioning. Simultaneously, after the second toothed plate 706 is in position, the second electromagnet 19 is de-energized, causing the previously compressed third spring 17 to release its pressure and reset. This causes the second limiting block 18 to move out of the second groove, with its upper part contacting the lower part of the second toothed plate 706, thus locking the second toothed plate 706 in place.
[0048] See Figure 5 A guide seat 20 is fixedly installed on the right side of the frame 1 near the second toothed plate 706. A third toothed plate 21 is movably installed inside the guide seat 20. The upper part of the third toothed plate 21 is fixedly connected to the laser cutter 10. A third rotating shaft 22 is rotatably installed on the upright plate 701. A third gear 23 is fixedly installed at the rear end of the third rotating shaft 22. The third gear 23 meshes with both the second gear 703 and the third toothed plate 21.
[0049] To improve the cutting efficiency of angle iron steel 24, after the two fixing mechanisms 8 fix the angle iron steel 24, the hydraulic rod 302 on the right side of the frame 1 drives the punching cutter 303 to punch the angle iron steel 24 and reset it. Then, the hydraulic rod 302 above the center of the frame 1 drives the punching cutter 303 to punch the angle iron steel 24 again. At this time, the two punching cutters 303 are inserted into the horizontal section side wall of the angle iron steel 24 to position the angle iron steel 24. Then, the third motor 901 reverses, causing the first sliding mechanism 5 and the second sliding mechanism 901 to reverse. Mechanism 7 simultaneously drives its respective fixing mechanism 8 to reset. At the same time, the third rotating shaft 22 rotates synchronously, driving the third gear 23 to rotate and causing the third toothed plate 21 to move downward. During the downward movement of the third toothed plate 21, the laser cutter 10 at its upper end works to cut the angle iron steel 24. After the cutting is completed, the hydraulic rod 302 located above the center of the frame 1 resets, resetting the two punching tools 303 that were originally inserted into the side wall of the horizontal section of the angle iron steel 24, so that the angle iron steel 24 is released from the limit and continues to be transported and processed through the conveying mechanism 2.
[0050] See Figures 1-12 In specific operation, the angle iron steel 24 is first pre-treated: a long section of the formed angle iron steel 24 is placed from the rear end of the frame 1 onto the conveying mechanism 2. At the same time, the angle iron steel 24 is guided and limited by the first limiting plate 404 and the second limiting plate 406 of the straightening mechanism 4. Driven by the conveying mechanism 2, the angle iron steel 24 moves toward the position of the limiting stop bar 11 until the front side of the angle iron steel 24 abuts against the limiting stop bar 11 and stops moving. The driving mechanism 9, in conjunction with the first sliding mechanism 5 and the second sliding mechanism 7, drives the fixing mechanism 8 to move toward the angle iron steel 24. Since no mounting holes are opened on the surface of the angle iron steel 24, after the positioning post 8024 abuts against the surface of the angle iron steel 24, it will be compressed into the sleeve 8022. Then, the hydraulic rod 302 located on the left side of the frame 1 drives the corresponding two punching blades. The tool 303 punches holes in the angle iron steel 24. Then, the hydraulic rod 302 above the center first drives the two punching tools 303 to cut two mounting holes in the lower part of the angle iron steel 24. At this time, the punching tools 303 do not reset and are inserted into the side wall of the horizontal section of the angle iron steel 24. Then, the drive mechanism 9 drives the first sliding mechanism 5 and the second sliding mechanism 7 to move in opposite directions, so that the fixing mechanism 8 is disengaged from the angle iron steel 24. The third rotating shaft 22 rotates synchronously with the second rotating shaft 702. The third gear 23 drives the third toothed plate 21 to move down. During the downward movement of the third toothed plate 21, the laser cutter 10 at its upper end works to cut the angle iron steel 24. Then, the two punching tools 303 that were originally inserted into the horizontal section of the angle iron steel 24 reset. At this time, four initial mounting holes are cut on the angle iron steel 24, completing the pre-processing of the angle iron steel 24.
[0051] Automatic continuous punching and cutting, and whole-section cutting: The angle iron steel 24 is driven to continue moving by the conveying mechanism 2. The main body of the angle iron steel 24 moves towards the limiting stop 11. At this time, the limiting stop 11 is below the horizontal section of the angle iron steel 24. During the movement of the angle iron steel 24, the part to be cut will move along with the main body of the angle iron steel 24 until the main body of the angle iron steel 24 is close to the limiting stop 11 at a certain distance. Then the cut part will automatically fall off the guide roller 202, and the limiting stop 11 will reset. The main body of the angle iron steel 24 will continue to move towards the limiting stop 11 and finally abut against the limiting stop 11. At this time, the driving mechanism 9, together with the first sliding mechanism 5 and the second sliding mechanism 7, controls the corresponding fixing mechanism 8 to move towards the main body of the angle iron steel 24. Finally, the positioning post 8024 on the fixing mechanism 8 is inserted into the pre-closed mounting hole on the main body of the angle iron steel 24 to position the main body of the angle iron steel 24. Then, the punching mechanism 3 punches holes in the vertical and horizontal sections of the angle iron steel 24 body. After punching the horizontal section of the angle iron steel 24 body, the two cutting tools 303 remain inserted in the angle iron steel 24 body. Then, the fixing mechanism 8 resets and no longer positions the angle iron steel 24 body. At the same time, the limit stop 11 moves again to the bottom of the horizontal section of the angle iron steel 24 body, so as not to obstruct its movement. During the reset process, the laser cutter 10 cuts the angle iron steel 24 body from top to bottom. At this time, the two cutting tools 303 are used to position the angle iron steel 24 body to ensure the cutting quality. The cut part is the angle iron blank. Then, the two cutting tools 303 that were originally inserted in the angle iron steel 24 body body are reset. At this time, the angle iron steel 24 body body is released from the limit and continues to move through the conveying mechanism 2. The cut angle iron blank falls from the guide roller 202. This cycle is repeated to process the next angle iron blank.
