Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a frame bending device. Background Technology

[0002] In the frame bending process, the shed frame, as a supporting component, typically needs to be bent into a U-shape to meet usage requirements. However, during transportation, to improve efficiency, the frame is usually in a straight shape. Bending is only performed after the frame arrives at the processing site.

[0003] Currently, the devices used for bending skeletons mainly include a transfer unit and a pushing unit. The transfer unit consists of multiple guide rollers and is responsible for pushing the skeleton to the designated position; the pushing unit consists of extrusion rollers and hydraulic components. The hydraulic components control the extrusion rollers to push the sides of the skeleton, thereby bending the moving skeleton into a preset shape.

[0004] However, the frame is usually made of metal and is quite heavy. When docking the frame with the transfer unit, the frame's straight-line direction needs to be adjusted to be at the same height and level as the transfer unit's conveying direction. Therefore, the frame also needs to be raised to a preset height before docking. This process not only increases the time required for bending the frame and reduces processing efficiency, but also, due to the frame's large mass, consumes time and effort during handling, further increasing the operational difficulty of the processing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a skeleton bending device that solves the problems of time-consuming and labor-intensive docking, low processing efficiency, and high operation difficulty in traditional skeleton bending devices when docking skeletons.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a skeleton bending device, comprising: The control panel has a support frame and a hydraulic rod on its lower side. The control panel is rotatably mounted on the upper end of the support frame, and the rotation angle of the control panel is controlled by the hydraulic rod. The transfer mechanism includes multiple guide wheels 1 mounted on the side of the operating table. The multiple guide wheels 1 are arranged in two rows, one above the other. The area between the two rows of guide wheels 1 is the transfer channel of the skeleton. One end of each row of guide wheels 1 is also provided with a guide wheel 2. A movable clamping wheel 3 is provided above the guide wheel 2. The clamping wheel 3 cooperates with the guide wheel 2 to clamp the skeleton and transfer it into the transfer channel. An extrusion roller, located at one end of the conveyor channel, is used for bending the skeleton; The detection mechanism is located on one side of the clamping wheel three and is used to detect the tilt angle of the skeleton clamped by the guide wheel two and the clamping wheel three. Clamping wheel three, in conjunction with guide wheel two, clamps the skeleton. At the same time, the detection mechanism detects the inclination of the skeleton. Subsequently, based on the detection data of the detection mechanism, the hydraulic rod controls the tilt angle of the operating table, so that the transmission channel of guide wheel one is consistent with the length direction of the skeleton.

[0007] As a further description of the above technical solution: the detection mechanism includes a support frame, one end of which is provided with a rotating frame that is rotatably assembled. The support frame and the rotating frame are connected in an elastic rotatable structure by a torsion spring. An inclination sensor is fixedly connected to the outer end of the rotating frame, and a bonding block is fixedly connected to the output end of the inclination sensor. The support frame moves with the clamping wheel three, and the bonding block is driven by the rotating frame to bond to the surface of the skeleton, so that the tilt sensor can detect the tilt of the skeleton.

[0008] As a further description of the above technical solution: a pull rope is connected to the upper side of the rotating frame, one end of the pull rope passes around the guide wheel on the upper side of the support frame and is connected to the side surface of the operating table, and one end of the pull rope is provided with a winding part.

[0009] As a further description of the above technical solution: the operating table includes a side plate one and a side plate two and a side plate three on one side. The middle of the side plate one and the side plate two and the side plate three is an assembly cavity. The side of the side plate one is rotatably connected to the upright. The lower end of the hydraulic rod is rotatably connected to the upright. The output end of the hydraulic rod is rotatably connected to the side plate one.

[0010] As a further description of the above technical solution: the inner assembly cavity of the operating table is provided with a drive assembly for driving the first guide wheel and the second guide wheel to rotate, and a motor for driving the drive assembly is provided on one side of the side plate.

[0011] As a further description of the above technical solution: the drive assembly includes: a main gear one coaxially mounted with the guide wheel one, and a main gear two coaxially mounted with the guide wheel two; The lower row of main gear 1 and main gear 2 are connected by a transmission structure through a secondary gear 2, and the two corresponding main gears 1 are connected by a pair of secondary gears 1.

[0012] As a further description of the above technical solution: the inner assembly cavity of the operating table is provided with a hydraulic component for controlling the movement of the clamping wheel three.

[0013] As a further description of the above technical solution: the inner assembly cavity of the operating table is provided with a hydraulic component two for controlling the movement of the extrusion wheel.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The tilt angle of the operating table is controlled by a hydraulic rod, ensuring that the conveyor channel of guide wheel one is aligned with the length direction of the skeleton. This guarantees that the skeleton can smoothly enter the conveyor channel, reducing adjustment time during skeleton loading. Furthermore, the tilting operating table can automatically unload the bent skeleton to one side, further improving production efficiency.

[0015] 2. Clamping wheel three and guide wheel two work together to clamp the skeleton and convey it into the conveyor channel. Guide wheel one works with the extrusion wheel to bend the skeleton into a preset shape, ensuring the accuracy and quality of the skeleton bending. Simultaneously, the tilt sensor in the detection mechanism can detect the tilt angle of the skeleton in real time. The controller adaptively controls the hydraulic rod based on the real-time feedback data, further ensuring the accuracy of the skeleton bending. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0020] A skeleton bending device includes an operating table 10, and a transfer mechanism 20, a pressing wheel 30 and a detection mechanism 40 on one side of the operating table 10.

[0021] Combination Figure 1 and Figure 2 The operating platform 10 is provided with a support frame 14 and a hydraulic rod 15 on its lower side. The operating platform 10 is rotatably mounted on the upper end of the support frame 14, and the rotation angle of the operating platform 10 is controlled by the hydraulic rod 15.

[0022] Specifically, the operating table 10 includes a first side plate 11 and two side plates 12 and 13 on one side. The middle of the first side plate 11 and the second and third side plates 13 is an assembly cavity. The side of the first side plate 11 is rotatably connected to the upright frame 14. The lower end of the hydraulic rod 15 is rotatably connected to the upright frame 14. The output end of the hydraulic rod 15 is rotatably connected to the first side plate 11. By controlling the extension of the output end of the hydraulic rod 15, the operating table 10 can be controlled to rotate around a rotating shaft on one side.

[0023] Combination Figures 3 to 6 The transfer mechanism 20 includes multiple guide wheels 21 mounted on the sides of side plates 2 and 3. The guide wheels 21 are arranged in two rows, one above the other. The two rows of guide wheels 21 are respectively mounted on one side of side plates 2 and 3. The area between the two rows of guide wheels 21 is the transfer channel for the skeleton. When the skeleton is located in the transfer channel and is held by the two rows of guide wheels 21, the skeleton can be moved in a preset direction by controlling the rotation of the guide wheels 21 in the corresponding direction.

[0024] Additionally, one end of a row of guide wheels 21 on one side of side plate 3 13 is also equipped with guide wheel 22, and a movable clamping wheel 23 is provided above guide wheel 22. Guide wheel 22, clamping wheel 23 and guide wheel 23 are of the same specifications as guide wheel 21 so as to clamp the same size skeleton accordingly. Clamping wheel 23 works with guide wheel 22 to clamp the skeleton and convey it into the conveying channel.

[0025] Specifically, the inner assembly cavity of the control panel 10 is provided with a drive assembly 24 for driving the first guide wheel 21 and the second guide wheel 22 to rotate, and a motor 25 for driving the drive assembly 24 is provided on one side of the side plate 11.

[0026] The drive assembly 24 includes: a main gear 241 coaxially mounted with the first guide wheel 21, and a main gear 242 coaxially mounted with the second guide wheel 22. The output end of the motor 25 is coaxially connected to either the first main gear 241 or the second main gear 242.

[0027] On one side of side plate 212, a row of main gears 241 and 242 are connected by a secondary gear 244, which drives the corresponding meshing main gears 241 and 242 to rotate in the same direction.

[0028] The two corresponding main gears 241 are connected by a pair of auxiliary gears 243. When the main gear 241 on the side of the side plate 2 12 rotates, it drives the corresponding main gear 241 on the upper side to rotate in the opposite direction through the pair of auxiliary gears 243. In this way, when the two corresponding main gears 241 clamp the frame and rotate in opposite directions, they can push the frame to one side.

[0029] The inner assembly cavity of the operating table 10 is provided with a hydraulic component 231 for controlling the movement of the clamping wheel 23. The hydraulic component 231 includes a slide module and a hydraulic push cylinder. The hydraulic push cylinder is used to push the moving platform on the slide module to move. The clamping wheel 23 is rotatably mounted on one side of the moving platform of the slide module. The moving block is controlled by the hydraulic push cylinder to move, and the clamping wheel 23 can be controlled to move closer to or away from the guide wheel 22.

[0030] The extrusion roller 30 is located at one end of the conveying channel and is used for bending the skeleton. The inner assembly cavity of the operating table 10 is equipped with a hydraulic component 21 for controlling the movement of the extrusion roller 30. The structure of the hydraulic component 21 is the same as that of the hydraulic component 1231. The extrusion roller 30 is controlled to move in the same way to push the side of the skeleton and bend the skeleton.

[0031] Combination Figure 4 and Figure 5 The detection mechanism 40 is set on one side of the clamping wheel 23 and is used to detect the tilt angle of the skeleton clamped by the guide wheel 22 and the clamping wheel 23.

[0032] Specifically, the detection mechanism 40 includes a support frame 41, which is fixedly mounted on one side of the movable stage of the hydraulic assembly 231 for rotating the clamping wheel 23. One end of the support frame 41 is equipped with a rotating frame 42 for rotating assembly. The support frame 41 and the rotating frame 42 are elastically rotatably connected by a torsion spring. The elastic potential energy of the torsion spring causes the rotating frame 42 to rotate towards the skeleton. An inclination sensor 43 is fixedly connected to the outer end of the rotating frame 42, and a contact block 44 is fixedly connected to the output end of the inclination sensor 43. As the support frame 41 moves with the clamping wheel 23, the contact block 44 is driven by the rotating frame 42 to contact the skeleton surface, allowing the inclination sensor 43 to detect the inclination of the skeleton.

[0033] It should be noted that the tilt sensor 43 has an internal level structure, which measures the tilt of the frame using the horizontal plane as a reference. Therefore, when the tilt sensor 43 moves downward with the rotating frame 42, causing a change in the angle of the tilt sensor 43 body, its measurement of the tilt of the frame based on the horizontal plane is not affected.

[0034] The working principle of the above mechanism is as follows: Before the skeleton is fed into the conveying channel of guide wheel 21, one end of the skeleton is placed on the upper side of guide wheel 22. Then, the clamping wheel 23 is lowered, so that clamping wheel 23 and guide wheel 22 clamp one end of the skeleton. At the same time, the support frame 41 on one side of clamping wheel 23 is lowered, causing one end of rotating frame 42 to adhere to the side surface of the skeleton via the mating block 44 connected by tilt sensor 43. At this time, the tilt angle of mating block 44 detected by tilt sensor 43 corresponds to the tilt of the skeleton. Subsequently, based on the detection data of tilt sensor 43, the tilt angle of operating table 10 is controlled by hydraulic rod 15, so that the conveying channel of guide wheel 21 is aligned with the length direction of the skeleton. Figure 7 As shown.

[0035] Once the adjustment is complete, the drive assembly 24 can be driven by the motor 25 to rotate the guide wheel 21 and the guide wheel 22, causing the skeleton to fully enter the conveying channel of the guide wheel 21. Then, the guide wheel 21 cooperates with the extrusion wheel 30 to bend the skeleton into the preset shape.

[0036] It should be noted that the coordination between the tilt sensor 43, hydraulic rod 15, hydraulic assembly 231, hydraulic assembly 31 and motor 25 is controlled by the controller.

[0037] When the hydraulic rod 15 controls the rotation angle of the operating table 10, the tilt angle of the frame, which rests on the upper side of the clamping wheel 23, also changes dynamically. Therefore, the controller adaptively controls the hydraulic rod 15 based on the real-time feedback data from the tilt sensor 43, ultimately ensuring that the tilt angle of the frame is consistent with the tilt angle of the side plate 11, so that the frame can smoothly enter the conveying channel of the operating table 10.

[0038] After the angle of the operating table 10 is adjusted, the skeleton is fed into the conveyor channel by rotating the clamping wheel 23. During this process, the inclination of the skeleton will change. In actual processing, the operating table 10 can be selectively controlled by the hydraulic rod 15 according to the range of inclination change.

[0039] In addition, combined Figure 8 and Figure 9 When the skeleton is bent and discharged from the other side of the operating table 10, the hydraulic rod 15 can control one end of the operating table 10 to rotate upward, so that the bent part of the skeleton is kept at a suitable height. On the one hand, this can prevent the bent part of the skeleton from having excessive swing, which would affect the bending effect of the clamping wheel 23. On the other hand, tilting the operating table 10 can automatically discharge the bent skeleton to one side, further improving production efficiency.

[0040] Combination Figures 2 to 5 A pull rope 45 is connected to the upper side of the rotating frame 42. One end of the pull rope 45 passes around the guide wheel on the upper side of the support frame 41 and is connected to the side surface of the operating table 10. One end of the pull rope 45 is provided with a winding part 451.

[0041] Specifically, when the support frame 41, which rises with the clamping wheel 23, tightens the pull rope 45, the continued rise of the support frame 41 can pull up the outer end of the rotating frame 42, causing the fitting block 44 to move away from the side of the frame. This action facilitates the subsequent placement of one end of another frame on the upper surface of the clamping wheel 23, making subsequent operations easier.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
