The driving components are symmetrically and fixedly installed on the upper surface of the support plate through bolts. The driving components include a servo motor, a turntable and a driving rod. A frame body is arranged on one side of the upper surface of the workbench close to the positioning column; in the utility model, the frame body is placed at a position on the surface of the workbench close to the positioning column, and the lengths of the two ends of the frame body extending are the same. Then, the positioning plate is pushed by an electric hydraulic push rod to move towards the frame body, and the position of the frame body is fixed by the positioning plate. Then, the servo motor is turned on, the turntable is driven to rotate by the servo motor, and at the same time, the driving rod is driven to rotate around the driving chute. Then, the rotating driving rod is used to push the frame body to bend around the axis of the positioning column, so as to bend the frame body into a U-shaped structure.

[0004] The above device can bend the headrest frame into shape at one time, but it cannot position the frame. When the frame is not in the middle position, the two sides of the frame are asymmetric after bending, and cutting or grinding is required, which affects the processing efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pipe bender for an automobile seat frame, which solves the problem that the existing pipe bender for the U-shaped headrest frame of an automobile seat cannot position the frame. When the frame is not in the middle position, the two sides of the frame are asymmetric after bending, and cutting or grinding is required, which affects the processing efficiency.

[0006] To achieve the above purpose, the utility model provides a pipe bender for an automobile seat frame, including a workbench, a limiting roller and a bending component. The limiting roller is installed on the workbench, and the bending component is arranged on the workbench. The pipe bender further includes a positioning component; the positioning component includes a mounting plate, a lifting seat, a positioning plate, a driving seat, a moving component and a pressing component. The mounting plate is fixedly connected with the workbench and is arranged on the workbench. The driving seat is slidably connected with the mounting plate and is located on one side of the mounting plate. The lifting seat is slidably connected with the mounting plate and is arranged on the mounting plate. The moving component is arranged on the lifting seat.

[0007] Wherein, the mounting plate includes a plate body and guide rods. The plate body is fixedly connected to the workbench, slidably connected to the driving seat, and is disposed on the workbench. The guide rods are fixedly connected to the plate body, slidably connected to the lifting seat, and penetrate through the lifting seat.

[0008] Wherein, the pressing member includes an electric push rod, a pressing plate and a connecting plate. The electric push rod is connected to the workbench and is located on one side of the workbench. The pressing plate is disposed on the electric push rod and is connected to the output end of the electric push rod.

[0011] When in use, for a tube bender for an automobile seat frame according to the present utility model, a steel tube to be processed is placed between the limiting rollers and the pressing member. At this time, the two positioning plates are located on the left and right sides of the steel tube. The moving member is used to drive the two positioning plates to approach each other, so that the two positioning plates can abut against both sides of the steel tube. During the movement of the two positioning plates, the steel tube is pushed to move, so that the midpoint of the steel tube is located at the central position of the two limiting rollers, thereby positioning the steel tube. At this time, the pressing member presses the steel tube against the limiting rollers. During the movement of the pressing member, the driving seat is driven to move, so that the driving seat moves away from the lifting seat. When the pressing member presses the steel tube tightly, the driving seat moves away from below the lifting seat. At this time, the lifting seat descends under the action of gravity, and then drives the positioning plate to descend, so that the positioning plate moves below the workbench, avoiding the interference of the positioning plate on the bending of the steel tube. Finally, the two sides of the steel tube are bent by the bending assembly, thereby achieving the purpose of positioning the steel tube and improving the processing efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] First Embodiment:

[0021] Please refer to Figures 1 to 4 , in which Figure 1 is the schematic diagram of the overall structure of the automotive seat frame pipe bender, Figure 2 is the schematic diagram of the structure of the positioning component, Figure 3 is the schematic diagram of the installation structure of the lifting seat, Figure 4 is the schematic diagram of the structure of the moving member.

[0022] The utility model provides an automobile seat frame bending machine, which comprises a workbench 101, a limiting roller 102, a bending assembly 103 and a positioning assembly 104. The positioning assembly 104 comprises a mounting plate 105, a lifting seat 106, a positioning plate 107, a driving seat 108, a moving member 109 and a pressing member 110. The mounting plate 105 comprises a plate body 111 and a guide rod 112. The pressing member 110 comprises an electric push rod 113, a pressing plate 114 and a connecting plate 115. The moving member 109 comprises a bidirectional screw 116, a driving motor 117 and a threaded sleeve 118. By driving the two positioning plates 107 to approach each other through the moving member 109, and then abutting against the two ends of the steel pipe, the steel pipe can be positioned. It can be understood that the foregoing solution can be used for positioning the steel pipe to be bent, and can also be used to lower the positioning plate 107 below the workbench 101 to avoid interference of the positioning rod during the bending of the steel pipe.

[0023] For this specific embodiment, the limiting roller 102 is installed on the workbench 101, the bending assembly 103 is arranged on the workbench 101, and there are two limiting rollers 102 and two bending assemblies 103. The two sides of the frame are bent by the two bending assemblies 103, so that the frame forms a U shape, achieving the purpose of one-time bending and forming and improving the processing efficiency.

[0024] Among them, the mounting plate 105 is fixedly connected to the workbench 101 and is arranged on the workbench 101. The driving seat 108 is slidably connected to the mounting plate 105 and is located on one side of the mounting plate 105. The lifting seat 106 is slidably connected to the mounting plate 105 and is arranged on the mounting plate 105. The moving member 109 is arranged on the lifting seat 106. The positioning plate 107 is connected to the lifting seat 106 through the moving member 109. The pressing member 110 is arranged on the workbench 101. There are two positioning plates 107. The moving member 109 can drive the two positioning plates 107 to approach or move away from each other. The pressing member 110 can press the skeleton against the limiting roller 102 and can also drive the driving seat 108 to move. There are mutually cooperating inclined surfaces on the driving seat 108 and the lifting seat 106, so that the movement of the driving seat 108 can drive the lifting seat 106 to lift and lower. During use, the steel pipe to be processed is placed between the limiting roller 102 and the pressing member 110. At this time, the two positioning plates 107 are located on the left and right sides of the steel pipe. The moving member 109 is used to drive the two positioning plates 107 to approach each other, so that the two positioning plates 107 can abut against both sides of the steel pipe. During the movement of the two positioning plates 107, the steel pipe is pushed to move, so that the midpoint of the steel pipe is located at the central position of the two limiting rollers 102, thereby positioning the steel pipe. At this time, the steel pipe is pressed against the limiting roller 102 through the pressing member 110. During the movement of the pressing member 110, the driving seat 108 is driven to move, so that the driving seat 108 moves away from the lifting seat 106. When the pressing member 110 presses the steel pipe, the driving seat 108 moves away from below the lifting seat 106. At this time, the lifting seat 106 descends under the action of gravity, and then drives the positioning plate 107 to descend, so that the positioning plate 107 moves below the workbench 101, avoiding the positioning plate 107 from interfering with the bending of the steel pipe. Finally, the bending assembly 103 bends both sides of the steel pipe, thereby achieving the purpose of positioning the steel pipe and improving the processing efficiency.

[0025] Secondly, the plate body 111 is fixedly connected to the workbench 101, is slidably connected to the driving seat 108, and is arranged on the workbench 101. The guide rod 112 is fixedly connected to the plate body 111, is slidably connected to the lifting seat 106, and penetrates through the lifting seat 106. There are four guide rods 112. The movement of the lifting seat 106 is guided through the guide rods 112, so that the lifting seat 106 can only lift and lower in the vertical direction along the guide rods 112.

[0026] Meanwhile, the electric push rod 113 is connected to the workbench 101 and is located on one side of the workbench 101; the pressing plate 114 is arranged on the electric push rod 113 and is connected to the output end of the electric push rod 113; the connecting plate 115 is fixedly connected to the pressing plate 114, is fixedly connected to the driving seat 108, and is arranged on the pressing plate 114; the electric push rod 113 drives the pressing plate 114 to move, so that the pressing plate 114 can press the steel pipe to be bent against the limiting roller 102; during the movement of the pressing plate 114, the connecting plate 115 is also driven to move, so that the connecting plate 115 drives the driving seat 108 to move, thereby achieving the purpose of driving the driving seat 108 to move.

[0027] In addition, the bidirectional screw rod 116 is rotatably connected to the lifting seat 106 and is located inside the lifting seat 106; the driving motor 117 is connected to the lifting seat 106 and is located on one side of the lifting seat 106, and the output end of the driving motor 117 is connected to the bidirectional screw rod 116; the threaded sleeve 118 is threadedly connected to the bidirectional screw rod 116, is slidably connected to the lifting seat 106, and is fixedly connected to the positioning plate 107; the thread directions on both sides of the bidirectional screw rod 116 are opposite, and two threaded sleeves 118 are arranged and are respectively located on both sides of the bidirectional screw rod 116 and are connected to the two positioning plates 107. By driving the bidirectional screw rod 116 to rotate through the driving motor 117, the bidirectional screw rod 116 drives the two threaded sleeves 118 to approach each other, thereby driving the two positioning plates 107 to approach each other.

[0028] When using the elbow pipe machine for automobile seat frames of this embodiment, place the steel pipe between the limiting rollers 102 and the pressing plate 114, and then start the driving motor 117 to drive the bidirectional screw 116 to rotate. The bidirectional screw 116 drives the two thread sleeves 118 to approach each other, and the two thread sleeves 118 drive the two positioning plates 107 to approach each other. Further, the positioning plate 107 pushes the steel pipe to move, so that the midpoint of the steel pipe is located at the central position of the two limiting rollers 102. At this time, start the electric push rod 113 to drive the pressing plate 114 to move, so that the pressing plate 114 presses the positioned steel pipe against the limiting rollers 102. During the movement of the pressing plate 114, it also drives the connecting plate 115 and the driving seat 108 to move, so that the driving seat 108 moves away from below the lifting seat 106. At this time, the lifting seat 106 descends under the action of gravity, and further drives the thread sleeve 118 and the positioning plate 107 to descend, so that the positioning plate 107 descends below the workbench 101, avoiding the positioning plate 107 interfering with the bending of the steel pipe. After the bending of the steel pipe is completed, the electric push rod 113 drives the pressing plate 114 to reset. At this time, it is convenient to take out the formed steel pipe. During the reset process of the pressing plate 114, it drives the connecting plate 115 and the driving seat 108 to reset, so that the driving seat 108 drives the lifting seat 106 to rise, and further drives the thread sleeve 118 and the positioning plate 107 to rise, thus facilitating the positioning of the next steel pipe to be processed, achieving the purpose of positioning the steel pipe and improving the processing efficiency.

The bending assembly 103 of this embodiment includes a support frame 201, a rotating motor 202, a rotating plate 203 and a bending roller 204.

[0031] For this specific embodiment, the support frame 201 is fixedly connected to the workbench 101 and is located on one side of the workbench 101; the rotating motor 202 is connected to the support frame 201 and is arranged on the support frame 201; the rotating plate 203 is arranged on the rotating motor 202 and is connected to the output end of the rotating motor 202; the bending roller 204 is rotatably connected to the rotating plate 203 and is located on one side of the rotating plate 203. By driving the rotating plate 203 to rotate through the rotating motor 202, and further driving the bending roller 204 to rotate around the limiting roller 102 as the center, the steel pipe is bent. The steel pipe is bent into a U shape at one time by the two bending assemblies 103, achieving the purpose of improving the processing efficiency.
