Description

Technical Field

[0001] The present application relates to the field of metal rod bending, and in particular to an automated bending device for multi-angle single-shot forming of bent pipes and a control system thereof. Background Art

[0002] A bending machine is a kind of processing equipment for rod and plate metal, which is mainly used to bend metal materials into the required angle or shape. It is widely used in metal processing, construction, automobile manufacturing, aerospace and other fields. The main function of a bending machine is to apply pressure to metal materials to make them undergo plastic deformation within the elastic limit, thereby achieving bending.

[0003] The working principle of the bending machine is relatively simple. The position of the bending die of the bending machine is adjusted, and the metal material to be processed is placed on the workbench of the bending machine. The metal material is transported between the block and the bending die of the bending machine. It is controlled by a computer numerical control system to achieve precise bending of complex shapes.

[0004] Since the design and manufacture of bending machines need to consider many factors, for bending machines for rod-shaped metals, the single cooperation of the mold and the block of most bending machines can only perform a single bending of a single metal rod. Although the stability is sufficient, the efficiency still needs to be improved. In view of the above-mentioned related technologies, the inventor believes that the structure of the bending machine can be improved to enable it to simultaneously bend a single metal rod at multiple angles, greatly improving production efficiency.

[0005] Application Contents In order to improve the bending efficiency of rod-shaped metals and optimize the bending process of metal materials, the present invention provides an automatic bending device for single-shot forming of bent pipes at multiple angles and a control system thereof.

[0006] On the one hand, the present invention provides an automatic bending device for forming a pipe at multiple angles in a single step, which adopts the following technical solutions: An automatic bending device for forming a pipe at multiple angles in a single step and a control system thereof, comprising a conveying platform, a clamping member is arranged at one end of the conveying platform, and a main mandrel is arranged at the other end, characterized in that it also comprises: A rotating plate is horizontally arranged, and one edge of one side is rotatably connected to one end of the conveying platform close to the main spindle, and the rotating plate and the main spindle are rotated synchronously with the main spindle as the center of the circle; A first fixed arm is arranged on the rotating plate corresponding to the main spindle, and rotates around the main spindle as the rotating plate rotates, and a push block is arranged at one end of the first fixed arm close to the main spindle; A rotating core shaft is vertically arranged and rotatably connected to a side of the rotating plate away from the main core shaft. The rotating core shaft rotates around the core shaft as the rotating plate rotates. The second fixed arm is rotatably connected to the rotating plate and is arranged corresponding to the rotating core shaft. With the rotating core shaft as the center of the circle, the second fixed arm rotates synchronously with the rotating core shaft. A push block is arranged at one end of the second fixed arm close to the rotating core shaft.

[0007] By adopting the above technical solution, in order to adapt to the shape and length of the metal rod body, the conveying platform is distributed in a long and narrow rectangular block as a whole, and the axial direction of the metal rod body is conveyed on the conveying platform parallel to the length direction of the conveying platform until the main body of the metal rod body extends above the rotating plate surface; In the initial state, the line between the main core shaft and the rotating core shaft is parallel to the conveying platform, and the rotating core shaft can be regarded as an extension of the conveying platform in the length direction. After the above-mentioned metal rod body is conveyed to the top of the rotating plate, its multi-bend parts should be aligned with the main core shaft and the rotating core shaft respectively, which is the preset position; the first fixed arm is set corresponding to the main core shaft, and the curvature of the push block at its end is equal to the curvature of the outer wall of the main core shaft, that is, the curvature of the two is adapted, similarly, the second fixed arm is set corresponding to the rotating core shaft, and the curvature of the push block at its end is equal to the curvature of the outer wall of the rotating core shaft. In other words, when the first fixed arm and the second fixed arm rotate around the corresponding main core shaft and the rotating core shaft respectively, they show circular motion; Therefore, the metal rod body is transported to a preset position, that is, one bending point is transported to between the first fixed arm and the main core shaft, and the other bending point is transported to between the second fixed arm and the rotating core shaft. When the push block rotates around the main core shaft, the push block rotates around the rotating core shaft, and different bending parts of the metal rod body are bent at the same time, thereby improving processing efficiency; It should be noted that since the rotation of the rotating plate around the main axis makes the rotation angle of the second fixed arm need to take into account the linear displacement of the rotating plate. Therefore, the preset rotation angle between the second fixed arm and the rotating axis should be greater than the bending angle of the metal rod body, and the extra angle is the linear displacement of the rotating plate.

[0008] Optionally, an adjustment groove is provided on the rotating plate corresponding to the rotating core shaft, the adjustment groove is perpendicular to the conveying direction of the metal rod body, and an adjustment slider adapted to the adjustment groove is formed at the bottom end of the rotating core shaft.

[0009] By adopting the above technical solution, the adjustment groove on the rotating plate is used to adjust the sliding movement of the slider, or to adjust the horizontal sliding movement of the rotating mandrel on the slider, and to adjust the position of the rotating mandrel perpendicular to the conveying direction of the metal rod body, specifically to align different sides of the rotating mandrel with different sides of the main mandrel; The length of the adjusting groove is greater than the length of the main core shaft, the rotating core shaft slides along the adjusting groove to one end of the adjusting groove, one side edge of the rotating core shaft is flush with one side edge of the main core shaft, and the metal rod body is transported to between one side edge of the main core shaft and one side edge of the rotating core shaft; the rotating core shaft slides along the adjusting groove to the other end of the adjusting groove, and at the same time changes the transport position of the metal rod body, and the metal rod body is transported to between one side edge of the main core shaft and the other side edge of the rotating core shaft; the bending direction requires that the metal rod body is on different side edges of the main core shaft, and the bending direction is the side of the metal rod body away from the main core shaft.

[0010] Optionally, also include: A pitch-adjusting screw is rotatably connected to the inside of the rotating plate, the rotating plate is provided with a screw groove corresponding to the pitch-adjusting screw, and the screw groove is connected to the adjusting groove; The pitch-adjusting slide plate is slidably connected to the lead screw groove, and the bottom end is threadedly connected and penetrates the lead screw. The top end of the pitch-adjusting slide plate is connected to the bottom end of the rotating core shaft, and the rotating core shaft slides along the lead screw groove as the lead screw rotates.

[0011] By adopting the above technical solution, the adjustment groove on the rotating plate is mainly used to adjust the distance between the rotating core shaft and the main core shaft, that is, different from the sliding of the rotating core shaft in another horizontal direction, the adjustment slider on the rotating core shaft slides along the adjustment groove, and the adjustment groove slides along the conveying direction of the metal rod body. By changing the distance between the rotating core shaft and the main core shaft, the distance between the bending angles of the metal rod body is changed, thereby adapting to the processing of metal rod bodies with different bending angles; The main adjustment method is to adjust the screw in the screw slot to rotate, drive the distance adjustment slide on it to slide, and then change the position of the rotating core shaft on the distance adjustment slide; Screw drive is a common transmission method. The advantages of its transmission are that it combines stability and precision, and has high self-locking performance. After stably sliding to the preset position, the screw is adjusted to stop rotating, so that the adjustable distance slide stops at the current position, which is suitable for the sliding requirements of the rotating shaft of this solution.

[0012] Optionally, also include: The height adjustment screw is vertically arranged between the core shaft and the conveying platform, and is rotatably connected to the end of the conveying platform. The core shaft is connected to the height adjustment screw. As the screw rotates, the core shaft rises and falls.

[0013] By adopting the above technical solution, the bending direction is realized by the sliding structure of the adjustment groove, and the bending point spacing is realized by the distance adjustment screw. In practical applications, the height adjustment screw is mainly used to adjust the height of the main core shaft and the rotating core shaft; Since the clamping member above the conveying platform needs to be rotated and extended along the length direction of the conveying platform in terms of structure, the additional active conveying member with a height change of the clamping member can easily reduce the operating cost of the bending equipment and reduce the structural stability of the clamping member during the conveying process of the metal rod; The two mandrels are disc metal parts with a certain thickness. Usually, circumferential grooves of different radii are usually opened at different heights on the main mandrel and the rotating mandrel. The circumferential grooves at the same height of the main mandrel and the rotating mandrel are adapted to change the bending angle of the bending parts of different metal rod bodies. When the bending angle changes, the lifting member changes the height of the main mandrel. When the height of the metal rod body remains unchanged, the height of the main mandrel and the rotating mandrel changes, so that the metal rod body is aligned with the circumferential grooves at different heights of the main mandrel and the rotating mandrel. Specifically, the height adjustment screw rotates to drive the rotating plate to rise and fall, thereby driving the main core shaft and the rotating core shaft on the rotating plate to rise and fall synchronously.

[0014] Optionally, also include: A conveyor rail is horizontally arranged on one side of the conveyor platform, and one end of the conveyor rail extends above the conveyor platform; The material conveying component is slidably connected to the material conveying rail, and is the part between the material conveying component and the core shaft.

[0015] By adopting the above technical solution, the setting of the feed rail and the feed assembly further improves the automation degree of the bending equipment in this solution. One end of the feed rail extends above the conveying table so that the feed assembly slides along the feed rail, and can clamp the metal rod body processed on the conveying table, maintain the clamping state, and transport the processed metal rod body to the conveying table along the end of the feed rail away from the conveying table; After the processing of a single metal rod is completed, the feed assembly transports a metal rod to be processed to the top of the conveyor table, and the clamping part feeds and clamps it. During the processing of the metal rod, the feed assembly is stably located at one end of the feed rail close to the conveyor table, waiting for the metal rod to complete a single processing.

[0016] On the one hand, the present invention provides a control system for an automated bending device for multi-angle single-shot forming of a bent pipe, which adopts the following technical solution: A control system for an automated bending device for forming a pipe at multiple angles in a single step, characterized in that it comprises a central control module, a front-end control module, a positioning acquisition module, and a display module; The central control module stores data files and instruction files pre-written by technicians. The central control module executes the instruction execution files in sequence and sends control instructions to the front-end control module, the positioning acquisition module, and the display module. The front-end control module stores a command execution file inside, receives the command of the central control module, and controls the rotation of the rotating plate and the second fixed arm; The positioning acquisition module acquires the positions and operation information of the rotating plate, the first fixed arm and the second fixed arm during the process of executing the instruction file of the front-end control module, and sends the acquisition results to the central control module; The display module is connected to the front-end control module and the positioning acquisition module to display the position and processing information of the metal rod.

[0017] By adopting the above technical solution, the central control module is the central control module in this solution, which has the data processing and computing capabilities and the ability to generate and issue instructions; the positioning acquisition module is usually a detection component set at the bending end of the automated bending equipment, which can use sensors, angle measuring instruments, etc.; the front-end control module is set one by one corresponding to the rotating plate and the rotating drive parts of the second fixed arm. Specifically, the front-end control module is mainly composed of control circuits of each rotating drive part; the display module is a control screen set inside the workshop, and the technicians can understand the various specific conditions of the equipment operation according to the display of the display module; Therefore, a complete feedback control chain is formed through the front-end detection of the positioning acquisition module, the data calculation and instruction generation of the central control module, and the specific control of the front-end calculation module to ensure the orderly operation of the automated bending equipment. Technicians can monitor the specific operation of the bending equipment through the display component.

[0018] Optionally, an alarm module is also included; The alarm module is connected to the positioning and collecting module. When the data collected by the positioning and collecting module is abnormal, the positioning and collecting module sends an alarm signal to the alarm module, and the alarm module issues an alarm according to the alarm signal.

[0019] By adopting the above technical solution, the alarm module is directly connected to the positioning acquisition module, and can instantly receive the data collected by the positioning acquisition module. When the data collected by the positioning acquisition module is abnormal, an alarm can be immediately generated; The alarm module can be connected to the display module, and when an alarm occurs, the display module will issue a prompt so that the technicians can obtain it immediately.

[0020] Optionally, a wireless module is also included; The wireless module is connected to the central control module, the front-end control module, and the positioning acquisition module, and is used for remote command transmission between the central control module and the front-end control module, and remote data transmission and reception between the central control module and the positioning acquisition module.

[0021] By adopting the above technical solution, the wireless module is used to replace the traditional wired data transmission, which improves the internal space utilization of the workshop and avoids the potential safety hazards caused by the entanglement of transmission lines; Correspondingly, the application space of wireless data modules is relatively small, so low-power, short-range wireless components can be selected to save costs.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a rotating plate and a first fixed arm and a second fixed arm that rotate synchronously with the main spindle, the tube can be bent at multiple angles in a single feeding process. This design significantly improves processing efficiency and ensures the consistency and accuracy of bending at various angles, thereby improving product quality; 2. By adopting the design of rotating mandrel and second fixed arm, bending operations at different angles can be completed without changing the bending die. This method not only reduces the need for manual intervention, but also ensures the stability and precision of each processing process, thereby improving the overall production efficiency; 3. The position of the rotating mandrel can be easily adjusted by using the adjusting slot and the adjusting slider. This adjustable design enables the equipment to better adapt to the processing needs of pipes of different sizes and shapes, greatly enhancing the application range and flexibility of the equipment and meeting various production and processing requirements.

The conveying platform 1 is integrally formed with the machine body and arranged at the top of the machine body. It is a long and narrow structure. A clamping member 11 for clamping and conveying a metal rod 6 is arranged on one side of the conveying platform 1. Since bending machines are relatively common, the clamping member 11 is varied. In this embodiment, the clamping member 11 is not limited, and a common rotatable and horizontally conveyable chuck can be used.

[0033] Reference Figure 1 and Figure 2 A feed rail 2 is provided on one side of the conveyor platform 1, and an electric clamp 22 is slidably connected to the feed rail 2. The feed rail 2 is horizontally arranged, and is supported by an integrally formed or fixed frame at the bottom, so that the rail surface height is higher than the table surface height of the conveyor platform 1. One end of the feed rail 2 extends above the table surface of the conveyor platform 1, so that the clamping end of the electric clamp 22 can contact the metal rod body 6; the clamping end of the electric clamp 22 is horizontally arranged, and the clamping ability of the electric clamp 22 is extended horizontally by the horizontal extension of the clamp. Specifically, the electric slide 21 is fixedly connected to the bottom of the body of the electric clamp 22, and the sliding of the electric slide 21 along the feed rail 2 drives the sliding of the electric clamp 22. Taking into account the structural interference of the metal rod body 6 during unloading, an electric cylinder is arranged between the top surface of the electric slide 21 and the bottom surface of the electric clamp 22.

The electric clamp 22 is driven to rise and fall in a horizontal state by extending and retracting the piston rod of the electric cylinder, thereby driving the metal rod body 6 that may have structural interference to rise and stay away from the metal processing workpiece.

[0034] Reference Figure 1 and Figure 2A lifting platform 12 is provided at one end of the conveying platform 1 away from the clamping member 11. The two sides of the lifting platform 12 are perpendicular to each other and are L-shaped. One side of the lifting platform 12 is vertical and the other side is horizontal. The vertically arranged side is in contact with the edge of the conveying platform 1. Two height adjustment screws 13 are vertically arranged on the edge of the conveying platform 1 corresponding to the vertically-adjusting side wall of the lifting platform 12. A slider is provided at the vertically-adjusting side edge of the lifting platform 12 corresponding to the two height adjustment screws 13. The slider is threadedly connected to the two height adjustment screws 13. The slider is driven to rise and fall by rotating the height adjustment screws 13, thereby driving the lifting platform 12 to rise and fall. The horizontal side of the lifting platform 12 is located at the top of its vertical side and extends to the side away from the conveying platform 1. The top of the horizontal side wall of the lifting platform 12 is rotatably connected with a rotating plate 5. The rotating plate 5 is arranged horizontally. The bottom edge of the vertical side of the lifting platform 12 is hinged with a support rod. The top of the support rod is fixedly connected to the plate surface of the rotating plate 5. During the rotation of the rotating plate 5, the support rod maintains a rotating contact effect on the rotating plate 5.

[0035] Reference Figure 1 and Figure 3A main core shaft 51 is arranged on one side edge of the rotating plate 5 close to the conveying platform 1 and on the top side of the connection between the rotating plate 5 and the lifting platform 12. The main core shaft 51 is a cylindrical boss structure. A circumferential groove 53 is opened on the top of the main core shaft 51. A plurality of circumferential grooves 53 are opened at different heights. The bottom surface of the circumferential groove 53 is an arc shape, which is adapted to the outer wall of the metal rod body 6 and is used for bending the metal rod body 6. The circumferences of the circumferential grooves 53 at different heights on the main core shaft 51 are different. The lifting platform 12 drives the rotating plate 5 to rotate so that the metal rod body 6 is aligned with different circumferential grooves 53. A rotary cylinder 55 is arranged below the lifting platform 12 corresponding to the main core shaft 51. The cylinder body of the rotary cylinder 55 is fixed on the table surface of the lifting platform 12. The piston rod of the rotary cylinder 55 passes through the lifting platform 12 and is connected with the rotating plate 5 and the main core shaft 51, serving as a rotating driving member for the main core shaft 51 and the rotating plate 5. A first fixed arm 3 is fixedly connected to the side wall of the main core shaft 51, and the first fixed arm 3, the main core shaft 51 and the rotating plate 5 rotate synchronously. The top surface of the first fixed arm 3 is horizontally arranged, and a push block 58 is slidably connected to the first fixed arm 3. The push block 58 is horizontally arranged, and an arc groove 57 is horizontally opened at one end of the push block 58 close to the main core shaft 51. The bottom of the arc groove 57 is adapted to the curvature of the outer wall of the metal rod body 6 and is used to clamp the metal rod body 6; the top end of the first fixed arm 3 is slidably connected to an electric slide 21 as a sliding drive component to drive the push block 58 to slide toward the side close to the main core shaft 51, until the arc groove 57 on the push block 58 clamps the metal rod body 6, and pushes the metal rod body 6 to move toward the circumferential groove 53 on the main core shaft 51, until the metal rod body 6 is restricted by the push block 58 and the main core shaft 51. In order to improve the stability of the metal rod body 6, an auxiliary arm 7 is provided on one side of the first fixed arm 3. The auxiliary arm 7 is arranged parallel to the first fixed arm 3. A push block 58 which is the same as the first fixed arm 3 is arranged above the auxiliary arm 7 and is also provided with an arc groove 57 adapted to the metal rod body 6. The auxiliary arm 7 and the push block 58 above the first fixed arm 3 are fed synchronously to fix the metal rod body 6 between the main core shaft 51 and the push block 58.

[0036] Reference Figure 1 and Figure 4 , a rotating shaft 52 is vertically arranged at one end of the rotating plate 5 away from the main shaft 51, the rotating shaft 52 is vertically arranged, and a plurality of circumferential grooves 53 are provided at the top of the rotating shaft 52, and the circumferential grooves 53 on the rotating shaft 52 correspond to the circumferential grooves 53 on the main shaft 51 one by one, and the circumferential grooves 53 corresponding to each other on the main shaft 51 and the rotating shaft 52 are equal in circumference and height, and the metal rod 6 can be fixed in the corresponding circumferential grooves 53 on the main shaft 51 and the rotating shaft 52 at the same time. A second fixed arm 4 is fixedly connected to the side wall of the rotating shaft 52, and a push block 58 similar to that on the first fixed arm 3 is slidably connected above the second fixed arm 4, and a circular arc groove 57 is also provided thereon, and similar to the auxiliary arm 7 on one side of the first fixed arm 3, an auxiliary arm 7 is also provided on one side of the second fixed arm 4. The repeated structure is not repeated.

[0037] Reference Figure 5 and Figure 6 A screw groove 54 is provided inside the rotating plate 5 on the side away from the conveying platform 1. A pitch-adjusting screw 541 is rotatably connected in the screw groove 54. The axial direction of the pitch-adjusting screw 541 is parallel to the conveying direction of the metal rod body 6. A pitch-adjusting slide plate 542 is threadedly connected and penetrated on the pitch-adjusting screw 541. The height of the pitch-adjusting slide plate 542 is adapted to the height of the screw groove 54, so that the pitch-adjusting slide plate 542 can slide and stably slide in the screw groove 54 with the rotation of the pitch-adjusting screw 541. The length direction of the pitch-adjusting slide plate 542 is perpendicular to the axial direction of the pitch-adjusting screw 541. The pitch-adjusting slide plate 542 is provided with a slide groove along its length direction, and a pitch-adjusting slider is correspondingly provided. The top height of the pitch-adjusting slider is higher than the plate surface of the rotating plate 5 and is connected to the bottom end of the rotating core shaft 52. Therefore, the sliding of the pitch-adjusting slide plate 542 itself and the sliding of the pitch-adjusting slider along the slide groove realize the sliding of the two perpendicular directions in the horizontal plane of the rotating core shaft 52. An adjusting groove 56 is provided on the surface of the rotating plate 5, or on the top wall of the screw groove 54. The adjusting groove 56 is penetrated through the screw groove 54 so that the adjusting groove 56 and the screw groove 54 are connected, or the screw groove 54 is connected to the outside through the adjusting groove 56. The width of the adjusting groove 56 is the same as the width of the pitch-adjusting slider, so that the sliding of the pitch-adjusting slider is limited by the adjusting groove 56. In this embodiment, a driving frame 543 is fixedly connected between the top of the pitch-adjusting slider and the bottom of the rotating core shaft 52. The bottom of the driving frame 543 is fixedly connected to the pitch-adjusting slider, and the top of the driving frame 543 is fixedly connected to the rotating core shaft 52. The driving frame 543 is hollowed out and provided with a rotary cylinder 55 for driving the rotating core shaft 52. The rotary cylinder 55 is vertically arranged, and its piston rod is connected to the bottom end of the rotating core shaft 52 to drive the rotating core shaft 52 to rotate independently, thereby driving the second rotating arm to rotate. In order to improve the stability of the second rotating arm, the side edge of the rotating plate 5 close to the rotating core shaft 52 is set in an arc shape, and an arc groove adapted to the arc edge of the rotating plate 5 is opened at the bottom end of the second rotating arm. The stability of the second rotating arm is improved by the clamping connection between the arc groove and the arc edge of the rotating plate 5.

[0038] The implementation principle of an automated bending device for single-forming multi-angle pipe bending and its control system in an embodiment of the present application is as follows: during a single bending process, the electric clamp 22 clamps the metal rod 6 and slides along the feed rail 2 to the top of the conveyor platform 1, and docks with the clamping member 11 above the conveyor platform 1.

[0039] The clamping member 11 conveys the metal rod body 6 until the two bent parts of the metal rod body 6 are aligned with the main core shaft 51 and the rotating core shaft 52 respectively, and the first fixed arm 3, the second fixed arm 4 and the two auxiliary arms 7 are fed simultaneously to fix the metal rod body 6 on the circumferential groove 53; then the rotating plate 5 rotates, and the first rotating arm rotates around the main core shaft 51 to bend the metal rod body 6, and at the same time, the second rotating arm rotates around the rotating core shaft 52 to bend another part of the metal rod body 6, thereby realizing simultaneous bending of multiple parts of the metal rod body 6 and single-time forming.

[0040] The technicians can adjust the distance between the main core shaft 51 and the rotating core shaft 52 by adjusting the distance screw 541; adjust the height of the lifting platform 12 by raising the screw 13, so that the metal rod body 6 corresponds to different circumferential grooves 53, and change the bending angle; change the position of the rotating core shaft 52 by adjusting the groove 56, so that the rotating core shaft 52 and the main core shaft 51 are respectively located on both sides of the metal rod body 6 or on the same side to change the bending direction of the metal rod body 6.

[0041] On the one hand, the embodiment of the present application discloses a control system for an automated bending device for forming a pipe at multiple angles in a single shot, which is used to control the automated bending device for forming a pipe at multiple angles in a single shot.

[0042] The central control module 8 stores data files and instruction files pre-written by technicians. The central control module 8 executes the instruction execution files in sequence and sends control instructions to the front-end control module 83, the positioning acquisition module 84, and the display module 81. In this embodiment, the central control module 8 selects a computer or a single-chip microcomputer with data processing and instruction sending and receiving functions, or a control component integrated in an automated machine tool. The front-end control module 83 stores instruction execution files, receives instructions from the central control module 8, controls the rotation of the rotary cylinder 55 of the rotating plate 5, the piston rod of the control cylinder of the second fixed arm 4, and controls the operation of the control components of the pitch adjustment screw 541 and the height adjustment screw 13.

[0043] The display module 81 is connected to the front-end control module 83 and the positioning acquisition module 84, and displays the control process of the front-end control module 83 and the various data collections of the positioning acquisition module 84. The display module 81 is directly connected to the central control module 8. In actual applications, the display module 81 generally selects a display component integrated on a computer or a machine tool control box.
