Description

Technical Field

[0001] This utility model relates to the field of rapid lifting device technology, and in particular to a rapid lifting device for the straightening rollers of a straightening machine. Background Technology

[0002] A straightening machine typically consists of a set of straightening rollers, a drive system, a frame, and an adjustment device. The straightening rollers are the core component of the straightening machine; they straighten metal strips or sheets using pressure and compression to make them flat. The straightening process requires adjusting the vertical position of the straightening rollers to accommodate materials of different thicknesses and hardnesses, ensuring the straightening effect. Therefore, a rapid lifting and lowering device for the straightening rollers needs to be designed.

[0003] Existing straightening machines generally use manual adjustment, which results in slow lifting speed, affecting production efficiency, low adjustment accuracy, and inability to accurately control the position of the rubber rollers, thus affecting the straightening quality. Therefore, it is necessary to design a device that can quickly rotate and lift the straightening rollers via a threaded rod. Furthermore, existing straightening machines inevitably generate vibrations during production operation, which may affect the straightening position of the straightening rollers on the straightening machine, reducing the straightening accuracy and quality. Utility Model Content

Existing straightening machines generally use manual adjustment, which results in slow lifting and lowering speeds, affecting production efficiency, low adjustment accuracy, and inability to accurately control the position of the rubber rollers, thus affecting the straightening quality. Therefore, it is necessary to design a device that can rapidly lift and lower the straightening rollers by rotating a threaded rod. Furthermore, existing straightening machines inevitably generate vibrations during production operation, which may affect the straightening position of the straightening rollers on the straightening machine, reducing the straightening accuracy and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid lifting device for the straightening roller of a straightening machine, comprising a straightening machine, an adjusting frame installed above the straightening machine, an opening cavity inside the adjusting frame, a lifting mechanism rotatably connected inside the cavity, a straightening frame installed at the bottom of the straightening machine, and shock-absorbing mechanisms fixedly connected to both the left and right sides of the straightening frame. The lifting mechanism includes a rotating shaft rotatably connected inside the cavity of the adjusting frame, drive motors installed on the left and right sides of the rotating shaft, a connecting piece sleeved on the outside of the rotating shaft, a threaded rod rotatably connected to the bottom of the connecting piece, and a sliding column slidably connected to the outside of the threaded rod. The shock-absorbing mechanism includes shock-absorbing frames fixedly connected to the left and right sides of the straightening frame, a shock-absorbing telescopic rod fixedly connected to the top surface of the shock-absorbing frame, a damping contraction rod fixedly connected to the middle of the top surface of the shock-absorbing frame, and a shock-absorbing spring sleeved on the outside of the damping contraction rod.

[0006] As a further embodiment of this utility model, a straightener A is fixedly connected to the bottom of the threaded rod, and a straightening wheel A is rotatably connected to the middle of the straightener A. The straightener A serves to straighten the external pipe.

[0007] As a further embodiment of this utility model, a rotating component is rotatably connected to the top surface of the straightening frame, and a straightener B is fixedly connected to the top of the rotating component. The rotating component serves to adjust the straightening angle.

[0008] As a further embodiment of this utility model, a straightening wheel B is rotatably connected to the middle of the straightener, and a pressure sensor is installed on the right side of the straightening wheel B. The pressure sensor controls the straightening pressure and achieves precise straightening.

[0009] As a further embodiment of this utility model, a support frame is fixedly connected to the back of the straightening frame, and the top right side of the support frame is fixedly connected to the back of the adjusting frame. The support frame serves to provide support and shock absorption on both sides.

[0010] As a further embodiment of this utility model, the bottom of the adjustment frame is fixedly connected to columns around its perimeter, and the bottom of the columns is fixedly connected to the top perimeter of the straightening frame. The columns provide stable support in the middle.

[0011] As a further embodiment of this utility model, the bottom four corners of the shock absorber are fixedly connected with support legs, and the inner side of the support legs is fixedly connected with a reinforcing rod. The support legs help to maintain balance on both sides.

[0012] This utility model provides a rapid lifting device for the straightening rollers of a straightening machine, which has the following beneficial effects:

[0013] 1. The rapid lifting device for the straightening rollers of this straightening machine, through the setting of the lifting mechanism, has an adjusting frame installed above the straightening machine during straightening. A drive motor is installed on the top of the adjusting frame, and an adapter is installed below the drive motor. The middle of the adapter is connected to a rotating shaft. The rotating shaft is connected to the connecting part and the threaded rod at the bottom of the connecting part, so that the threaded rod can rotate rapidly. The rotation of the threaded rod causes the sliding column outside the threaded rod to move up and down, thereby driving the straightener A at the bottom to move up and down. This adapts to the need to straighten pipes of different sizes, achieving the function of precise lifting and lowering, and avoiding the reduction in the accuracy and quality of straightening due to the slow speed of manual lifting.

[0014] 2. The rapid lifting device for the straightening rollers of this straightening machine, through the setting of a shock-absorbing mechanism, addresses the vibration generated during the straightening process of the machine's normal operation. This vibration indirectly affects the straightening position of the straightener B above the straightening frame. Therefore, shock-absorbing frames are installed on both sides of the straightening frame. Inside the shock-absorbing frames are shock-absorbing telescopic rods and damping contraction rods, and outside the damping contraction rods are shock-absorbing springs. The setting of the shock-absorbing springs can effectively reduce and offset the vibration generated by the device, thereby mitigating the vibration and preventing the straightening device inside the straightening machine from lacking precise positioning due to vibration, which would result in poor straightening quality.
