Description

Technical Field

[0001] The present application relates to the field of pipe bending machines, and in particular to a stabilizing device for pipe bending machines. Background Art

[0002] The tires and body of most modern cars are connected by suspension. The body of the vehicle is actually suspended on the tires by the suspension. The suspension is usually composed of springs. The suspension can ensure that all the tires of the car are in contact with the ground when the car is driving on an uneven road. The impact force received by the car when driving on an uneven road will be buffered by the suspension, so that the actual impact force received by the car body is smaller, greatly improving driving comfort.

[0003] However, the success or failure of the car lies in the suspension. For the sake of comfort, the stiffness of the car suspension is relatively small, which causes the vehicle body to tilt in the direction of the turn when turning, posing certain safety hazards. Therefore, a stabilizer bar is installed between the two suspensions of the front wheels of the car. The stabilizer bar is formed by bending spring steel, and the two ends of the stabilizer bar are fixed on the left and right suspensions respectively. When the vehicle tilts during turning, the stabilizer bar will support the vehicle body and reduce the degree of tilt of the vehicle, thereby improving the safety of the vehicle while driving.

[0004] Usually, the bending and forming of automobile stabilizer bars is achieved by a pipe bending machine. During production, one end of the spring steel bar is coaxially clamped and fixed on the main clamp of the main clamp of the pipe bending machine, and then the pipe bending machine is started. The main clamp moves to drive one end of the spring steel bar to move to the wheel mold and fit with the side wall of the wheel mold. The guide mold of the pipe bending machine blocks and fixes one end of the spring steel bar, and then the clamping die of the pipe bending machine is started to push the spring steel bar to bend along the side wall of the wheel mold. After bending, the clamping die and the guide die are withdrawn, and the main clamp drives the spring steel bar to continue to move toward the wheel mold. At the same time, the main clamp drives the spring steel bar to rotate according to the designed angle, and then the clamping die and the guide die move forward to cooperate with the wheel mold to bend the spring steel bar. The above process is repeated many times until the overall bending and forming of the spring steel bar is completed.

[0005] However, since the material of the steel rod used to make the automobile stabilizer bar is spring steel and the spring steel rod is relatively slender, the spring steel rod will vibrate greatly during the bending process. During the bending process, if the guide die directly pushes the vibrating spring steel rod against the side wall of the wheel die for bending, the vibrating spring steel rod will have a greater impact on the guide die and the wheel die, resulting in a large gap between the actual service life and the theoretical service life of the guide die and the wheel die. Therefore, when using a pipe bender to bend the spring steel rod in the factory, the staff usually hold the spring steel rod with their hands to manually cushion the vibration of the spring steel rod.

[0006] However, in the process of manually stabilizing the spring steel bar, since the main clamp used to clamp and fix the spring steel bar needs to drive the spring steel bar to move toward the wheel mold, the worker's hands may be pinched by the cooperation between the main clamp and the wheel mold, and the worker's hands may be injured if the vibration of the spring steel bar is buffered by the hands for a long time, which is not conducive to the personal safety of the worker. Summary of the invention

[0007] In order to solve the problem that manual stabilization of a pipe bender when bending spring steel bars may cause injuries to workers, the present application provides a stabilizing device for a pipe bender.

[0008] The stabilizing device of a pipe bending machine provided in the present application adopts the following technical solution:

[0009] A stabilizing device for a pipe bending machine comprises a frame, a mounting frame is slidably mounted on the frame, the sliding direction of the mounting frame is parallel to the feeding direction of a spring steel bar when being bent on the pipe bending machine, a mounting rod is rotatably mounted on the mounting frame, the rotation plane of the mounting rod is vertical, a stabilizing mechanism for stabilizing the spring steel bar is arranged on one end of the mounting rod away from the mounting frame, a driving mechanism for driving the mounting frame to slide is arranged on the frame, and the mounting frame is provided with a driving motor for driving the mounting rod to rotate.

[0010] By adopting the above technical solution, when the pipe bending machine is working, the driving mechanism drives the mounting frame to slide to a suitable position, and then the driving motor is started to drive the mounting rod to rotate until the stabilizing mechanism is located at the spring steel bar of the pipe bending machine, and then the stabilizing mechanism stabilizes the spring steel bar, so that when the pipe bending machine bends the spring steel bar, the staff does not need to stabilize the spring steel bar manually, and the staff's hands are not easily injured when operating the pipe bending machine, thereby protecting the staff's personal health.

[0011] Optionally, the stabilizing mechanism includes a stabilizing block mounted on an end of the mounting rod facing away from the mounting frame, two mounting plates are rotatably mounted on the stabilizing block, the rotation axes of the two mounting plates are parallel to each other and the two mounting plates can be rotated to be parallel to each other, shock-absorbing springs are provided on opposite sides of the two mounting plates, a clamping plate is installed on an end of the shock-absorbing spring away from the mounting plate, the clamping plate is provided with an arc groove, the axes of the arc grooves of the two clamping plates are parallel to the feeding direction of the pipe bending machine, the mounting rod can be rotated until the two clamping plates clamp the spring steel rod on the pipe bending machine, and a driving member for driving the mounting plate to rotate is provided on the stabilizing block.

[0012] By adopting the above technical solution, when the stabilizing block rotates to the top of the spring steel rod, the driving member starts to drive the two mounting plates to rotate until the abutting plate fits against the side wall of the spring steel rod, and when the spring steel rod vibrates, the vibration-damping spring connected to the abutting plate can buffer and absorb the vibration of the spring steel rod, so that the spring steel rod is maintained at a relatively stable level. Since the vibration-damping spring is used for buffering, the vibration of the spring steel rod in multiple directions can be absorbed by the vibration-damping spring, and since the spring steel rod is flexibly stabilized by the vibration-damping spring, when bending, if the straightness of the spring steel rod is low, the position of the spring steel rod at one end of the wheel mold will be offset, and the vibration-damping spring will compensate for the deviation of the spring steel rod, so that the abutting plate is not easily damaged.

[0013] Optionally, mounting grooves are provided on opposite sides of the two mounting plates, a fixed plate is slidably installed in the mounting groove, one end of the shock-absorbing spring on the mounting plate is installed on the fixed plate, an adjusting bolt is rotatably installed on the mounting plate, one end of the adjusting bolt is threadedly connected to the fixed plate, and the adjusting bolt is used to push the fixed plate to slide.

[0014] By adopting the above technical solution, when bending spring steel bars of different diameters, the bending machine needs to replace the mold, and the clamping plate also needs to be replaced. The clamping plate can be conveniently removed by turning the adjusting bolt to slide the fixed plate out of the installation groove. For spring steel bars of different diameters, the distance between the two clamping plates is also different. By turning the adjusting bolt to drive the two fixed plates to slide, the distance between the two clamping plates can be conveniently adjusted.

[0015] Optionally, the driving member includes a driving cylinder installed on the stabilizing block, the piston rod of the driving cylinder extends and retracts in a direction away from the two mounting plates, the piston rod of the driving cylinder is perpendicular to the rotation axis of the mounting plate, and a virtual triangle formed by three points, namely, one end of the piston rod of the driving cylinder away from the driving cylinder and the rotation axes of the two mounting plates, is an isosceles triangle, and a connecting rod is installed on each of the two mounting plates, and one end of the connecting rod away from the mounting plate is rotatably connected to the piston rod of the driving cylinder, and when the piston rod of the driving cylinder is extended, the piston rod of the driving cylinder pushes the two mounting plates to rotate to be parallel to each other through the two connecting rods.

[0016] By adopting the above technical solution, the two mounting plates are driven by the driving cylinder, so that the rotation of the two mounting plates is relatively fast and the rotation angle of the two mounting plates is relatively accurate and less prone to errors.

[0017] Optionally, the stabilizing block is rotatably connected to the mounting rod via a connecting shaft, the connecting shaft is horizontal, and a rotating motor for driving the connecting shaft to rotate is provided on the mounting rod. A clamping block is provided on the piston rod of the driving cylinder, and the connecting rod is rotatably mounted on the clamping block. An arc groove is provided on a side wall of the clamping block facing away from the driving cylinder, and the axis of the arc groove is horizontal and both ends of the arc groove penetrate the opposite side walls of the clamping block. The mounting rod and the stabilizing block are rotatably adjusted until the clamping block faces the spring steel rod on the pipe bending machine. At this time, starting the driving cylinder can push the side wall of the arc groove to press against the side wall of the spring steel rod to press and fix the spring steel rod on the guide die of the pipe bending machine.

[0018] By adopting the above technical solution, when the spring steel bar is bent at the last section, the main clamp has loosened the remaining part of the spring steel bar and returned to its original position. At this time, the spring steel bar is clamped and fixed on the wheel die. Therefore, when the spring steel bar is bent at the last section, the rotating motor is started to drive the stabilizing block to rotate until the clamping block faces the spring steel bar, and then the driving cylinder is started to push the clamping block to clamp the spring steel bar, and the spring steel bar is clamped and fixed on the guide die, so that the spring steel bar will not fall directly from the pipe bender after the clamping die is withdrawn after the last section is bent, so that the staff is not easily injured by the spring steel bar when removing the bent spring steel bar from the pipe bender.

[0019] Optionally, the clamping block includes a connecting block and a fixed block, the connecting block is connected to the piston rod of the driving cylinder, a connecting groove is provided on the connecting block, one end of the fixed block is embedded in the connecting groove, the arc groove is provided on the fixed block, and a fixing piece for fixing the fixed block is provided on the connecting block.

[0020] By adopting the above technical solution, for spring steel bars of different diameters, the fixing block can be replaced to adapt to spring steel bars of different diameters, so that when the piston rod of the driving cylinder extends in the same shape, the fixing block can press against the spring steel bar to fix the spring steel bar on the guide die.

[0021] Optionally, a plurality of mounting holes are provided on the side wall of the connecting groove, a fixing ball is slidably installed in the mounting hole, a fixing spring is provided between the fixing ball and the bottom of the mounting hole, two ends of the fixing spring are respectively connected to the fixing ball and the bottom of the mounting hole, a plurality of fixing holes corresponding to the mounting holes are provided on the side wall of the fixing block, and when the fixing block is fitly embedded in the connecting groove, the fixing balls are fitly embedded in the fixing holes one by one.

[0022] By adopting the above technical solution, after one end of the fixing block is fitted and embedded in the connecting groove, the fixing block can be conveniently fixed to the connecting block through the fit between the fixing ball and the fixing hole.

[0023] Optionally, the driving mechanism includes a screw rod and a positioning motor mounted on the frame, the screw rod being rotatably mounted on the frame, the screw rod passing through the mounting frame and threadedly engaged with the mounting frame, the positioning motor being mounted on the frame, and the output shaft of the positioning motor being transmission connected to the screw rod, a positioning rod being provided on the mounting frame, one end of the positioning rod extending to a side of a main clamp of the pipe bender away from the frame, a receiver being mounted on one end of the positioning rod located on a side of the main clamp away from the frame, a laser transmitter being provided on the mounting frame, the laser emitted by the laser transmitter being obstructed by the main clamp of the pipe bender, a PLC module being provided on the frame, the PLC module being used to control the driving motor, driving cylinder, rotating motor and positioning motor, and a reset button being installed on the frame for starting the PLC module to reset the driving motor, driving cylinder, rotating motor and positioning motor.

[0024] By adopting the above technical solution, when the main clamp slides toward the wheel mold to block the laser transmitter, the PLC module receives the signal from the receiver and starts the positioning motor to drive the screw to rotate, thereby driving the mounting frame to slide, so that the stabilizing block is always in a more suitable position. When the number of signals received by the PLC module is the number of bending times required for one end of the spring steel bar, the driving cylinder is started to open the two mounting plates, the rotating motor is started to drive the mounting rod to reset, and the laser transmitter and receiver continue to count the number of bending times. When the count reaches the last time, the PLC module starts the rotating motor and the driving motor. The rotating motor drives the stabilizing block to rotate until the driving cylinder faces the end away from the mounting rod, and the rotating motor drives the mounting rod to rotate until the fixed block faces the spring steel rod, and then the driving cylinder is started to push the fixed block against the spring steel rod to complete the fixation of the spring steel rod. When the spring steel rod needs to be removed, hold the spring steel rod and press the reset button. After the auxiliary device is reset, the spring steel rod is removed and stored, which further reduces the difficulty of the staff's operation of the stabilizing device to maintain the stability of the spring steel rod.

[0025] Optionally, an alarm electrically connected to the PLC module is installed on the frame, and when the driving cylinder starts to push the fixing block to press the spring steel rod against the guide mold for more than a specified time, the PLC module activates the alarm.

[0026] By adopting the above technical solution, the alarm is used to remind the operator to remove the spring steel rod, which is conducive to improving work efficiency.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the pipe bender is working, the driving mechanism drives the mounting frame to slide to a suitable position, and then the driving motor starts to drive the mounting rod to rotate until the stabilizing mechanism is located at the spring steel bar of the pipe bender. Then the stabilizing mechanism stabilizes the spring steel bar, so that when the pipe bender is bending the spring steel bar, the staff does not need to stabilize the spring steel bar manually, and the staff's hands are not easily injured when operating the pipe bender, which protects the staff's personal health;

[0029] 2. When the spring steel bar is bent at the last section, the main clamp has loosened the remaining part of the spring steel bar and returned to its original position. At this time, the spring steel bar is clamped and fixed on the wheel die by the clamping die. Therefore, when the spring steel bar is bent at the last section, the rotating motor is started to drive the stabilizing block to rotate until the pressing block faces the spring steel bar, and then the driving cylinder is started to push the pressing block to press against the spring steel bar, and the spring steel bar is pressed and fixed on the guide die, so that the spring steel bar will not fall directly from the pipe bender after the clamping die is withdrawn after the last section of bending is completed, so that the staff is not easily injured by the spring steel bar when removing the bent spring steel bar from the pipe bender;

[0030] 3. When the main fixture slides toward the wheel mold to block the laser transmitter, the PLC module receives the signal from the receiver and starts the positioning motor to drive the screw to rotate, thereby driving the mounting frame to slide, so that the stabilizing block is always in a more suitable position. When the number of signals received by the PLC module is the number of bending times required for one end of the spring steel bar, the driving cylinder is started to open the two mounting plates, and the rotating motor is started to drive the mounting rod to reset. The laser transmitter and receiver continue to count the number of bending times. When the count reaches the last time, the PLC module starts the rotating motor and the driving motor. The rotating motor drives the stabilizing block to rotate until the driving cylinder faces the end away from the mounting rod, and the rotating motor drives the mounting rod to rotate until the fixed block faces the spring steel rod, and then the driving cylinder is started to push the fixed block against the spring steel rod to complete the fixation of the spring steel rod. When the spring steel rod needs to be removed, hold the spring steel rod and press the reset button. After the auxiliary device is reset, the spring steel rod is removed and stored, which further reduces the difficulty of the staff's operation of the stabilizing device to maintain the stability of the spring steel rod.

An adjusting bolt 323 is rotatably mounted on the opposite side of the mounting plates 32, and one end of the adjusting bolt 323 passes through the mounting plate 32 and is threadedly connected to the fixing plate 322.

[0042] Reference Figure 3 and Figure 4 A plurality of damping springs 33 are fixedly mounted on opposite sides of the two fixed plates 322.

[0043] Reference Figure 3 and Figure 4 Rotating the mounting rod 22 and the stabilizing block 31 can make the stabilizing block 31 rotate until the two mounting plates 32 are respectively located on both sides of the spring steel bar of the pipe bending machine. At this time, after the two mounting plates 32 are rotated to be parallel to each other, the side walls of the arc-shaped grooves 4 of the two abutting plates 34 are respectively in contact with the side walls on both sides of the length direction of the spring steel bar.

[0044] Reference Figure 3 and Figure 4 A PLC module 86 is provided on the frame 1, and the PLC module 86 is used to drive the rotation motor 56 and the drive motor 21 to start and stop. A driving member 5 is provided on the stabilizing block 31, and an embedding groove is provided on one side wall of the stabilizing block 31 where the connecting shaft 55 is installed.

[0045] Reference Figure 3 and Figure 4A connecting rod 52 is provided on each of the two mounting plates 32, and a cylindrical rotating rod 53 is provided on one end of the connecting rod 52. The rotating rod 53 is parallel to the rotation axis of the mounting plate 32. A T-shaped slot 54 is provided on the opposite side of the two mounting plates 32. The length direction of the T-shaped slot 54 is arranged along the vertical direction of the rotation axis of the mounting plate 32. One end of the connecting rod 52 provided with the rotating rod 53 slides through the T-shaped slot 54, and the rotating rod 53 is slidably installed in the T-shaped slot 54.

[0046] Reference Figure 3 and Figure 4 A clamping block 6 is fixedly installed on the piston rod of the driving cylinder 51, and the end of the connecting rod 52 away from the mounting plate 32 is rotatably connected to the clamping block 6, and the rotation axes of both ends of the connecting rod 52 are parallel to the rotation axis of the mounting plate 32.

[0047] Reference Figure 3 and Figure 4 When the piston rod of the driving cylinder 51 is retracted, the two connecting rods 52 on the piston rod of the driving cylinder 51 push the two mounting plates 32 to rotate until the two abutting plates 34 are in contact with the side walls of the spring steel rod. At this time, the adjusting bolt 323 can be rotated to push the two fixing plates 322 to slide toward each other, so that the abutting plates 34 abut against the side walls of the spring steel rod. The distance between the two abutting plates 34 can be adjusted by adjusting the bolt 323 to drive the fixing plates 322 to slide, so as to adapt to spring steel rods of different diameters. At the same time, it is also convenient to disassemble and replace the abutting plates 34 of different diameters for adaptation when spring steel rods of different diameters are used.

[0048] Reference Figure 1 and Figure 2 A positioning rod 83 is fixedly installed on the mounting frame 2, one end of the positioning rod 83 extends to the side of the main clamp of the pipe bending machine away from the frame 1, a laser transmitter 85 is fixedly installed on the mounting frame 2, and a receiver 84 is fixedly installed on the end of the positioning rod 83 away from the mounting frame 2 for receiving the laser signal of the laser transmitter 85, and the receiver 84 is electrically connected to the PLC module 86.

[0049] Reference Figure 2 and Figure 3When the pipe bender has finished bending the spring steel bar once, the main fixture drives the spring steel bar to move toward the wheel die to the position of the next bending. At this time, the main fixture blocks the laser emitted by the laser transmitter 85. After the receiver 84 detects that the signal disappears, it transmits the signal to the PLC module 86. The PLC module 86 starts the positioning motor 82 to drive the screw rod 81 to rotate, thereby pushing the mounting frame 2 to slide toward the wheel die. At the same time, the driving cylinder 51 is started to extend the piston rod of the driving cylinder 51, and the two mounting plates 32 rotate in opposite directions to separate the clamping plate 34 from the spring steel bar. When the mounting frame 2 slides to the receiver 84 and receives the signal from the laser transmitter 85 again, the positioning motor 82 stops, the piston rod of the driving cylinder 51 is retracted, and the clamping plate 34 is pressed against the side wall of the spring steel bar again for stability.

[0050] Reference Figure 2 and Figure 3 When the PLC module 86 detects through the receiver 84 that the bending times of one end of the spring steel bar reaches the specified times, that is, after one end of the spring steel bar is bent, the driving cylinder 51 is started to drive the two mounting plates 32 to rotate away from each other and open, and then the driving motor 21 is started to drive the mounting rod 22 to rotate to vertical, and the stabilizing block 31 leaves the spring steel bar. Since the length of the section of the spring steel bar to be bent is shorter at this time, the vibration generated during the bending is smaller, and there is no need to stabilize the spring steel bar at this time.

[0051] Reference Figure 2 and Figure 5 The abutting block 6 on the driving cylinder 51 includes a rectangular connecting block 61 and a rectangular fixing block 62. The connecting block 61 is fixedly mounted on the piston rod of the driving cylinder 51. Both connecting rods 52 are rotatably mounted on the connecting block 61. A connecting groove is provided on the end surface of the connecting block 61 away from the driving cylinder 51. One end of the fixing block 62 is fitted and embedded in the connecting groove. The connecting block 61 is provided with a fixing member 7. The fixing member 7 includes a plurality of mounting holes 71 provided on the side wall of the connecting groove. A fixing ball 72 is slidably installed in the mounting hole 71. The fixing ball 72 is fixedly connected to the bottom of the mounting hole 71 by a fixing spring 73. A plurality of fixing holes 74 corresponding to the mounting holes 71 are provided on the side wall of the fixing block 62. The fixing ball 72 is fitted and embedded in the fixing hole 74.

[0052] Reference Figure 2 and Figure 3An arc groove 4 is provided on a side wall of the fixed block 62 away from the mounting block, the axis of the arc groove 4 is horizontal and parallel to the axis of the spring steel bar on the pipe bender. When the spring steel bar is bent for the last time, the PLC module 86 starts the rotating motor 56 and the driving motor 21, and the mounting rod 22 and the stabilizing block 31 are respectively driven by the driving motor 21 and the rotating motor 56 until the arc groove 4 of the fixed block 62 faces the spring steel bar on the pipe bender. At this time, the driving cylinder 51 starts to extend the piston rod, and the side wall of the arc groove 4 of the fixed block 62 fits tightly against the spring steel bar. The spring steel bar is tightly fixed on the guide die 10 by the fixed block 62, so that the spring steel bar will not fall directly from the pipe bender after the last bending of the spring steel bar is completed.

[0053] Reference Figure 1 An alarm 9 is fixedly installed on the rack 1, and a reset button is fixedly installed on the rack 1. The reset button is electrically connected to the PLC module 86. The reset button is used to reset the mechanism on the rack 1. When the spring steel bar is bent, if the reset button is not pressed within a certain period of time, the PLC module 86 activates the alarm 9 to remind the staff to remove the spring steel bar.

[0054] The implementation principle of a stabilizing device for a pipe bending machine in an embodiment of the present application is as follows: when the pipe bending machine is started, the PLC module 86 is started synchronously, and the PLC module 86 drives the mounting frame 2 to slide to the specified position through the positioning motor 82, and then drives the mounting rod 22 to rotate through the driving motor 21 and drives the stabilizing block 31 to rotate through the rotating motor 56, so that the two mounting plates 32 are respectively located on both sides of the spring steel rod, and then the driving cylinder 51 is started to push the two mounting plates 32 to rotate through the two connecting rods 52 to fit the clamping plate 34 against the side wall of the spring steel rod, thereby completing the stabilization of the spring steel rod.

[0055] After the spring steel bar is bent once, the main clamp drives the spring steel bar to slide while blocking the laser of the laser transmitter 85, and the receiver 84 sends a signal. The PLC module 86 starts the positioning motor 82 to drive the mounting frame 2 to slide to the next specified position, and repeats this process until one end of the spring steel bar is bent. The PLC module 86 resets the mounting rod 22 and the stabilizing block 31, and at the same time, the PLC module 86 continues to drive the mounting frame 2 to move synchronously with the main clamp through the positioning motor 82.

[0056] When the last bending of the spring steel bar is detected through the cooperation between the laser transmitter 85 and the receiver 84, the PLC module 86 rotates the mounting rod 22 and the stabilizing block 31 to the specified position by the rotating motor 56 and the driving motor 21, and then starts the driving cylinder 51. The driving cylinder 51 pushes the fixing block 62 to press the spring steel bar against the guide mold 10 and starts timing. When the timing ends, the alarm 9 issues a completion alarm prompt, and the staff presses the reset button to reset the structure on the frame 1 and removes the bent automobile stabilizer bar.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
