Description

Technical Field

[0001] This invention relates to the field of aluminum tube bending processing, and particularly to an automatic processing device for bending aluminum tubes for toilet lift pads. Background Technology

[0002] Toilet riser pads with matching aluminum grab bars are widely used in accessible bathrooms, elderly care facilities, and other scenarios, requiring specific and high technical standards for bending precision, structural strength, and aesthetic integrity. The core processing step for these aluminum grab bars is bending the aluminum tubes, which must be strictly guaranteed to have a regular curvature, no damage to the tube wall, and no obvious scratches to meet the requirements of subsequent assembly processes and the load-bearing safety standards during actual use. Currently, most automated processing equipment on the market for bending small aluminum grab bars focuses on optimizing core functions such as bending angle control and feeding positioning accuracy. Their overall processing flow often adopts a simple automated operation mode of feeding, bending, and unloading, lacking an effective pre-treatment step for the aluminum tubes before bending, especially the wiping and cleaning process for the tube surface.

[0003] Existing automated processing equipment for bending aluminum handrails generally lacks a corresponding wiping and cleaning mechanism at the front end of the bending station. During the initial cutting, transportation, and storage processes, dust, metal shavings, oil stains, and oxide layers easily adhere to the outer wall of the aluminum tube. These foreign objects are sent into the bending die along with the aluminum tube. During the bending process, these foreign objects can damage the surface of the aluminum tube, thereby affecting the product's appearance quality and reducing the automated processing efficiency of aluminum handrails for toilet lifters. Summary of the Invention

[0004] This invention addresses the common problem in existing technologies where a matching wiping and cleaning mechanism is not installed at the front end of the bending station. During the initial cutting, transportation, and storage processes, aluminum tubes are prone to accumulating foreign matter such as dust, metal shavings, oil stains, and oxide layers on their outer walls. These foreign matter are sent into the bending mold along with the aluminum tubes, resulting in a significant reduction in subsequent processing efficiency. This invention provides an automatic processing device for bending aluminum tubes for toilet lift pads.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An automatic processing device for bending aluminum toilet lifter tubes includes a base frame with two sets of automatic bending modules, a drive clamping module fixed to the top surface of the base frame for conveying the aluminum toilet lifter tubes to the automatic bending modules and bending them using the automatic bending modules, a cleaning module disposed on one side of the drive clamping module for surface cleaning of the aluminum toilet lifter tubes, and a positioning component for vertically limiting the aluminum toilet lifter tubes. It also includes: The cleaning module includes a hydraulic drive cylinder fixed to the top of the base frame by a bracket. An outer shell that can be fitted onto the outside of the aluminum handrail tube of the toilet lifter is installed on the outside of the output end of the hydraulic drive cylinder. The inner wall of the outer shell is provided with a second cleaning component that is in contact with the outer wall of the aluminum handrail tube of the toilet lifter and wipes its outer wall. A corrugated pipe is rotatably connected to the outer wall of the outer shell. An air passage and an air groove communicating with the inner cavity of the corrugated pipe are opened inside the outer shell. The outer wall of the output end of the hydraulic drive cylinder is equipped with a first cleaning component that is attached to the inner wall of the aluminum handrail tube of the toilet riser and wipes its inner wall. The hydraulic drive cylinder drives the first and second cleaning components to move axially along the aluminum grab handle tube of the toilet lift pad, so as to simultaneously clean the inner and outer walls of the tube.

[0006] The above solution enables simultaneous and comprehensive cleaning of the inner and outer walls of the aluminum grab handle tube of the toilet lift pad, effectively avoiding bending defects caused by foreign matter residue on the tube wall; the hydraulically driven cylinder provides a stable and adjustable clamping force, which can be adapted to the cleaning needs of aluminum grab handle tubes of different diameters, improving the versatility of the device.

[0007] Preferably, a pair of second electric telescopic rods are symmetrically installed on the side wall of the fixed end of the hydraulic drive cylinder, and the output end of the second electric telescopic rod is fixedly connected to a protrusion.

[0008] Using the above solution: the cooperation between the second electric telescopic rod and the protrusion can achieve auxiliary adjustment and locking of the overall position of the cleaning module.

[0009] Preferably, the outer casing has an annular groove on the side near the second electric telescopic rod to guide and limit the protrusion, and the protrusion and the annular groove are adapted to each other.

[0010] The above solution, with its shape-adaptive design of the protrusion and the annular groove, allows the second electric telescopic rod to form a precise annular limit and guide for the outer casing during the extension and retraction process. This prevents the outer casing from radially deflecting under the drive of the hydraulic cylinder, ensuring that the second cleaning component on the inner wall of the outer casing always fits against the outer wall of the aluminum handrail tube, thus improving cleaning accuracy.

[0011] Preferably, a horizontal plate frame is fixedly connected to the end of the bellows away from the hydraulic drive cylinder, and a first spring sleeved on the outside of the bellows is fixedly connected to the end of the horizontal plate frame near the hydraulic drive cylinder. The end of the first spring away from the horizontal plate frame is fixedly connected to the bracket.

[0012] When the horizontal plate frame is blocked from moving laterally by the positioning member, the first spring will be compressed, causing the corrugated pipe to be compressed and the gas inside it to be blown through the air passage and air groove onto the surface of the aluminum handrail tube of the toilet lift pad to be bent.

[0013] The above solution is adopted: when the horizontal plate frame is blocked by the positioning component and cannot move laterally, the compression design of the first spring can automatically compensate for the displacement deviation during the positioning process of the pipe, and at the same time provide elastic restoring force for the corrugated pipe to ensure that the corrugated pipe and the end of the aluminum handrail pipe are fitted and sealed, thus ensuring the stability of the air supply to the air channel and air groove.

[0014] Preferably, the end of the first cleaning component away from the hydraulic drive cylinder is in a converged state towards the central axis, and the end of the outer casing away from the hydraulic drive cylinder is in an extended state extending outward.

[0015] The above solution is adopted: the converging end of the first cleaning component and the extended end of the outer shell component form a structural fit with the inner and outer walls of the tube. The converging first cleaning component can extend more accurately and smoothly to the inner wall of the aluminum handrail tube; the extended outer shell component can smoothly extend to the outer wall of the aluminum handrail tube, ensuring that all areas of the outer wall can be covered and cleaned by the second cleaning component, without any cleaning dead corners.

[0016] Preferably, the middle area between the second and first cleaning components is used to place the aluminum grab handle tube of the toilet riser to be bent; the outer casing is threadedly connected to the output end of the hydraulic drive cylinder.

[0017] The above solution uses the middle area between the second and first cleaning components as a placement reference for the pipe to be bent, ensuring that the pipe maintains a stable central axis during cleaning and transportation, thus avoiding pipe displacement that could lead to cleaning position deviation or bending positioning errors.

[0018] Preferably, the positioning component includes a frame bolted to the top surface of the base frame and located in the middle area between the cleaning module and the automatic bending module. A first electric telescopic rod is fixedly connected to the middle of the bottom surface of the frame, and a pad for supporting the aluminum handrail tube of the toilet riser to be bent is fixedly connected to the output end of the first electric telescopic rod.

[0019] The above solution is adopted: the positioning component drives the pad plate to rise and fall through the first electric telescopic rod to achieve precise vertical positioning of the pipe, ensuring that the pipe is always at the preset processing height during cleaning and bending, and avoiding incomplete cleaning or bending angle deviation due to pipe shaking or displacement. Preferably, the pad is arc-shaped, and the lateral spacing in the middle area of ​​the frame is greater than the diameter of the outer shell and the drive clamping module.

[0020] The above solution allows the arc-shaped pad to fit snugly against the outer curvature of the aluminum handrail tube, increasing the contact area, improving the stability of the tube support, preventing the tube from slipping or shaking during lifting or transport, and further ensuring positioning accuracy.

[0021] Preferably, an "L"-shaped abutment is fixed to the outer side of the output end of the first electric telescopic rod, and a stop is abutted at the top of the abutment. The baffle is in the shape of an inverted "L"; When the abutment is driven upward, it will contact the stop frame, causing the stop frame to rotate and thus blocking the middle area of ​​the frame.

[0022] Using the above solution: When the first electric telescopic rod drives the stop rod upward, it rotates by contacting the reverse "L"-shaped stop, which can quickly achieve the blocking and limiting of the middle area of ​​the frame. After the pipe is cleaned and before bending, the position of the pipe is locked in time to prevent the pipe from shifting during the bending process and ensure the accuracy of the bending angle.

[0023] Preferably, the stop is rotatably connected to the frame via a rotating shaft and a mounting base that are fixedly connected to each other. The frame is bolted to the frame, and a spring plate is installed at the connection end between the stop and the rotating shaft to allow the stop to elastically return to its original position.

[0024] The above solution involves a rotating connection between the stop and the mounting base via a pivot, which, combined with the elastic reset action of the spring plate, enables the stop to automatically reset.

[0025] This invention, by employing the above technical solutions, achieves significant technical advantages: Through the coordinated action of the first and second cleaning components, it enables simultaneous and comprehensive cleaning of the inner and outer walls of the aluminum handrail tube to be bent, effectively resolving automatic processing defects caused by foreign matter residue. A hydraulically driven cylinder provides a stable and adjustable driving force, propelling the first cleaning component into the tube. Combined with the positioning support of the second electric telescopic rod, this ensures a tight fit with the inner wall, efficiently removing foreign matter. Simultaneously, the outer casing moves and rotates, causing the second cleaning component to wipe the outer wall from all directions, thoroughly removing hard debris and oil stains, ensuring the smoothness of the tube and preventing bending defects.

[0026] Furthermore, as the outer casing moves towards the bending station, the horizontal frame is blocked by the positioning component, thereby compressing the first spring and the bellows. The internal gas is then blown outwards from the aluminum tube via the air passage and air groove. This pre-blowing can remove loose foreign objects in advance, reduce the wiping load, prevent foreign objects from being pressed into the tube wall, and simultaneously dry residual oil and moisture, reducing bending friction resistance, ensuring uniform stress, effectively avoiding bending defects, and improving the product qualification rate.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 10 As shown, the present invention provides an automatic processing device for bending aluminum toilet lifter tubes, including a base frame 100 with two sets of automatic bending modules 200 installed, a drive clamping module 300 fixed to the top surface of the base frame 100 for conveying the aluminum toilet lifter tube to the automatic bending module 200 and bending it using the automatic bending module 200, a cleaning module 500 disposed on one side of the drive clamping module 300 for surface cleaning of the aluminum toilet lifter tube, and a positioning member 400 for vertically limiting the aluminum toilet lifter tube, and further including: The cleaning module 500 includes a hydraulic drive cylinder 520 fixed to the base frame 100 via a bracket 510. The outer side of the output end of the hydraulic drive cylinder 520 is equipped with a housing 570 that can be fitted onto the outer side of the aluminum handrail tube of the toilet riser. The inner wall of the housing 570 is provided with a second cleaning component 580 that is in contact with the outer wall of the aluminum handrail tube of the toilet riser and wipes its outer wall. The outer wall of the housing 570 is rotatably connected to a corrugated pipe 5120. The interior of the housing 570 is provided with an air passage 5130 and an air groove 590 that communicate with the inner cavity of the corrugated pipe 5120. A first cleaning component 530 is installed on the outer wall of the output end of the hydraulic drive cylinder 520, which is attached to the inner wall of the aluminum handrail tube of the toilet riser and wipes its inner wall. The hydraulic drive cylinder 520 drives the first cleaning component 530 and the second cleaning component 580 to move axially along the aluminum grab handle tube of the toilet lift pad, so as to simultaneously clean the inner and outer walls of the tube.

[0031] It should be noted that the inner and outer walls of the aluminum handrail tube can be cleaned simultaneously. The hydraulic drive cylinder 520 can be adapted to different tube diameters, improving versatility. Combined with the corrugated pipe 5120, air passage 5130 and air groove 590 to blow away impurities, a dual cleaning effect is formed, which solves the defects such as tube wall scratches and flattening caused by not cleaning before bending from the root.

[0032] A pair of second electric telescopic rods 540 are symmetrically installed on the side wall of the fixed end of the hydraulic drive cylinder 520, and a protrusion 550 is fixedly connected to the output end of the second electric telescopic rod 540.

[0033] It should be noted that the second electric telescopic rod 540 and the protrusion 550 can assist in adjusting and locking the position of the cleaning module 500 to ensure its coaxiality with the pipe; at the same time, they provide lateral support for the hydraulic drive cylinder 520 to prevent it from deviating during operation and ensure cleaning consistency and reliability.

[0034] The outer casing 570 has an annular groove 560 on the side near the second electric telescopic rod 540 to guide and limit the protrusion 550, and the protrusion 550 and the annular groove 560 are adapted to each other.

[0035] A horizontal plate frame 5100 is fixedly connected to the end of the bellows 5120 away from the hydraulic drive cylinder 520. A first spring 5110 is fixedly connected to the end of the horizontal plate frame 5100 near the hydraulic drive cylinder 520 and sleeved on the outside of the bellows 5120. The end of the first spring 5110 away from the horizontal plate frame 5100 is fixedly connected to the bracket 510.

[0036] When the horizontal frame 5100 is blocked from moving laterally by the positioning member 400, the first spring 5110 will be compressed, which will compress the bellows 5120 and cause the gas inside it to blow through the air passage 5130 and the air groove 590 onto the surface of the aluminum handrail tube of the toilet lift pad to be bent.

[0037] It should be noted that when the horizontal plate frame 5100 is blocked, the compression of the first spring 5110 can compensate for the displacement deviation and ensure the air supply of the bellows 5120. The airflow, together with the second cleaning component 580, forms a double cleaning, which thoroughly removes impurities and reduces the defect rate. At the same time, it protects the bellows 5120 and extends the service life of the device.

[0038] The first cleaning component 530 is in a convergent state towards the central axis at the end away from the hydraulic drive cylinder 520, while the outer casing 570 is in an outwardly extending state at the end away from the hydraulic drive cylinder 520.

[0039] It should be noted that: the first cleaning component 530 gathers at the inner wall of the pipe, and the outer casing 570 expands the coverage of the outer wall. The two work together to allow the pipe to enter smoothly into both the inner and outer walls.

[0040] The middle area between the second cleaning component 580 and the first cleaning component 530 is used to place the aluminum grab handle tube of the toilet riser to be bent; the outer casing 570 is threadedly connected to the output end of the hydraulic drive cylinder 520.

[0041] The positioning component 400 includes a frame 410 bolted to the top surface of the base frame 100 and located in the middle area between the cleaning module 500 and the automatic bending module 200. A first electric telescopic rod 420 is fixedly connected to the middle of the bottom surface of the frame 410. A pad 430 for supporting the aluminum handrail tube of the toilet riser to be bent is fixedly connected to the output end of the first electric telescopic rod 420.

[0042] It should be noted that the first electric telescopic rod 420 drives the pad 430 to lift, which can be adapted to different pipe diameters and bending heights, and accurately limits vertical movement.

[0043] The pad 430 has an arc shape, and the lateral spacing in the middle area of ​​the frame 410 is greater than the diameter of the outer shell 570 and the drive clamping module 300.

[0044] An "L"-shaped abutment 440 is fixed to the outer side of the output end of the first electric telescopic pole 420. The top of the abutment 440 abuts against a stop 450. The stop 450 is in the reverse "L" shape. When the abutment 440 is driven upward, it will cause the stop 450 to rotate by abutting against the stop 450, so that the stop 450 blocks the middle area of ​​the frame 410.

[0045] The stop 450 is rotatably connected to the frame 410 via a rotating shaft 460 and a mounting base 470 that are fixedly connected to each other. The frame 410 is bolted to the frame 410. A spring plate 480 is installed at the connection end between the stop 450 and the rotating shaft 460 to allow the stop 450 to elastically return to its original position.

[0046] It should be noted that: the spring plate 480 enables the stop 450 to automatically reset, which facilitates subsequent pipe feeding and realizes the cycle of the limit process; the bolt connection of the mounting base 470 facilitates maintenance, and the spring plate 480 has adjustable elasticity to ensure continuous and efficient operation of the device.

[0047] Working principle and usage process of this invention: First, place the aluminum handrail tube of the toilet riser to be bent in the middle area of ​​the frame 410 and on the top surface of the pad 430. Start the first electric telescopic rod 420 so that its output end can drive the pad 430 and the aluminum handrail tube of the toilet riser to be bent to move upward and move to the same level as the cleaning module 500. Secondly, when the output end of the first electric telescopic rod 420 is running, it will contact the stop frame 450 through the abutment rod 440 and rotate around the pivot 460. At this time, the stop frame 450 will block the middle area of ​​the frame 410. The hydraulic drive cylinder 520 and the second electric telescopic rod 540 are activated respectively, causing the first cleaning component 530 and the second cleaning component 580 to move towards the inner and outer walls of the aluminum handrail tube of the toilet riser to be bent. The output end of the hydraulic drive cylinder 520 will clean and wipe the inner wall of the aluminum handrail tube of the toilet riser to be bent through the first cleaning component 530. Next, the output end of the second electric telescopic rod 540 is quickly pushed to move the outer shell 570 on the output end of the hydraulic drive cylinder 520. The outer shell 570 will rotate. The rotating outer shell 570 and the second cleaning member 580 clean and wipe the outer wall of the aluminum handrail tube of the toilet lift pad to be bent. Then the horizontal plate frame 5100 will be blocked by the frame body 410 and the corrugated pipe 5120 will be compressed, so that the gas inside the corrugated pipe 5120 will blow onto the surface of the aluminum handrail tube of the toilet lift pad to be bent through the air passage 5130 and the air groove 590. Finally, when the cleaning module 500 finishes cleaning and is reset, with the assistance of the operator, the cleaned aluminum handrail tube of the toilet riser pad to be bent is placed into the inside of the output end of the drive clamping module 300 through the pad plate 430 for fixed positioning; and then automatically bent by the automatic bending module 200.

[0048] It should be noted that the first cleaning component 530 and the second cleaning component 580 can be wiping cloths with wiping properties, and the connecting area is detachable and can be replaced by operators regularly. The specific cleaning material and parts used can be selected according to the actual application.

[0049] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
