Description

Technical Field

[0001] The utility model relates to the field of pipe processing equipment, and particularly relates to a straightening machine. Background Art

[0002] At present, most welded pipe units in the industry adopt the ordinary W forming process. When the high-frequency straight seam welded pipe unit of this process produces products of different specifications, there are corresponding technical requirements for product pipes of different lengths and specifications. The whole unit includes a rough forming section, a fine forming section, a welding and extrusion section, and a sizing and straightening section. Therefore, whether the straightness of the product pipe meets the standard directly affects the production quality of the production line.

[0003] Generally, there will be a special person on the production line to dynamically and real-time monitor the straightness of the product pipe during production. If it is found that the straightness exceeds the standard, it is necessary to adjust the relative position of the two straightening machines relative to the rolling center line to eliminate the bending of the product pipe. When the special person adjusts the position of the straightening machine, the speed and simplicity of the straightening machine adjustment directly affect the number of unqualified pipes and the first-pass rate of the equipment. Moreover, the safety problem of equipment operation during the production process is of utmost importance. The existing straightening machine adjustment requires manual shutdown and adjustment, and the position of the entire straightening machine needs to be adjusted, which is very time-consuming and laborious. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a straightening machine with high adjustment efficiency and low energy consumption.

[0005] In order to achieve the above object, the utility model provides a straightening machine, which includes a base, on which a lifting mechanism is arranged. The lifting mechanism is connected with an integral lifting frame. Two parallel slide rails are arranged on the integral lifting frame. The slide rails are connected with a transverse movement frame through sliders. The transverse movement frame is connected with a transverse movement driving mechanism through a transition plate. The transverse movement driving mechanism is connected with the integral lifting frame; a straightening roll is fixed on the transverse movement frame.

[0006] Optionally, the transition plate is connected to the middle of one side of the transverse movement frame. The output shaft of the transverse movement driving mechanism is connected with the transverse movement frame. The transverse movement driving mechanism drives the transverse movement frame to move back and forth on the slide rails.

[0007] Optionally, the transverse movement driving mechanism includes a motor. The output shaft of the motor is connected with a speed reducer. The output shaft of the speed reducer is connected with the transition plate through a nut and screw.

[0008] Optionally, the lifting mechanism includes a lifting motor. The lifting motor is connected with a plurality of lifting rods. The lifting rods are respectively arranged around the integral lifting frame and are connected with the integral lifting frame.

[0011] Optionally, a plurality of guide rods are arranged around the overall lifting frame.

[0013] The beneficial effects of the present utility model compared with the prior art are as follows: The straightening roll of this straightening machine is installed on the transverse movement frame, and the transverse movement frame system contains a transition plate connected to the transverse movement elevator in the overall lifting frame system. When adjusting the relative position of the straightening roll relative to the rolling center line, only the relative position of the structure inside the transverse movement frame needs to be adjusted to complete the adjustment of the straightening machine, so as to adjust the straightness of the product, making the adjustment efficiency higher and the energy consumption lower.

[0020] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is merely for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings and thus should not be construed as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some of the terms mentioned in the specification of this application may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of this description.

[0021] Referring to Figures 1-3 , this embodiment provides a straightening machine, which includes a base 1, on which a lifting mechanism 2 is provided. The lifting mechanism 2 is connected to an overall lifting frame 3, and the overall lifting frame 3 is driven by the lifting mechanism 2 to move up and down as a whole, thereby adjusting the up and down position of the straightening machine.

[0022] In this embodiment, the lifting mechanism 2 includes a lifting motor 21. A plurality of lifting rods 22 are connected to the lifting motor 21. The plurality of lifting rods 22 are connected to each other through a coupling 23. The lifting rods 22 are respectively arranged around the overall lifting frame 3 and are connected to the overall lifting frame 3. By driving the motor 21 to drive the plurality of liftings 22 to move up and down, the entire lifting frame 3 is driven to move up and down, with fast adjustment and high stability.

[0023] In some other embodiments, the lifting mechanism 2 can also be a hydraulic rod, and the hydraulic rod is connected to the middle of the overall lifting frame 3. In addition, in order to ensure the stability during the adjustment process, a plurality of guide rods can be arranged around the overall lifting frame 3 to ensure the stability during the lifting process.

[0024] Further, two parallel sliding rails 4 are installed on the overall lifting frame 3. The sliding rails 3 are connected to a transverse movement frame 5 through sliders (not shown in the figure). The transverse movement frame 5 is connected to a transverse movement driving mechanism 7 through a transition plate 6. The transverse movement driving mechanism 7 is connected to the overall lifting frame 3. A straightening roll 8 is fixed on the transverse movement frame 5.

[0025] In this embodiment, the transition plate 6 is connected to the middle of one side of the transverse movement frame 5. The output shaft of the transverse movement driving mechanism 7 is connected to the transverse movement frame 5. The transverse movement driving mechanism 7 drives the transverse movement frame 5 to move back and forth on the sliding rails 4. During the use of the traditional overall transverse movement mechanism, it is necessary to drive the overall equipment to move to adjust the relative position of the four rolls of the straightening machine relative to the rolling center line. However, for the straightening machine provided in this embodiment, only the transverse movement frame 5 needs to be moved during use, without moving the overall equipment, which saves more space during use and reduces the energy consumption of the power device.

[0026] In this embodiment, the transverse movement driving mechanism 7 includes a motor 71. The output shaft of the motor 71 is connected to a speed reducer 72. The output shaft of the speed reducer 72 is connected to the transition plate 6 through a nut and screw (not shown in the figure).

[0027] In order to make the overall force of the straightening machine more uniform, the straightening roll 8 is installed in the middle of the transverse movement frame 5. In this way, during the process of adjusting the position and during the operation of the straightening machine, the force can be dispersed to the entire straightening machine, and the stability is high.

[0028] When the maintenance personnel maintain the straightening machine provided in this embodiment, they do not need to stand on the base table containing emulsified liquid and bend down to maintain the power device. They only need to stand beside the base to complete the maintenance and daily maintenance work, thereby improving the production capacity of the production line and reducing the power consumption of the straightening machine. Experiments show that for the same specification units, when using the improved overall transverse movement structure, the energy consumption of the transverse movement motor can be reduced by 20%, and the later maintenance time can be saved by 15%, and the maintenance operation is safer.

[0029] The straightening roll 8 of the straightening machine provided in this embodiment is installed on the transverse movement frame 5. The transverse movement frame 5 contains a transition plate 6 connected to the transverse movement driving mechanism 7 in the overall lifting frame 3. When adjusting the relative position of the straightening roll relative to the rolling center line, only the transverse movement frame 5 needs to be adjusted to complete the adjustment of the straightening machine to adjust the straightness of the product, and the force application point of the improved overall transverse movement structure of the straightening machine is more reasonable, while reducing the overall transverse movement power consumption.

[0030] The above is only the embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
