[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a clamping and straightening device for steel structure production, including a straightening frame 1. The top of the straightening frame 1 has a pressing part, and the inner side of the straightening frame 1 has a straightening part. The straightening part includes an inlet / outlet 111, a lower roller 21 below the inlet / outlet 111, side rollers 23 on the left and right sides of the inlet / outlet 111, and a moving roller 22 above the inlet / outlet 111. The cross-section of the inlet / outlet 111 intersects with the lower roller 21 and the side rollers 23, respectively. A steel column can be inserted into the inlet / outlet 111, and the steel column is tangent to the lower roller 21 and the side rollers 23, respectively. The pressing part includes sliding plates 33 located on both sides of the moving roller 22. The axis of the moving roller 22 is perpendicular to the plane of the sliding plates 33. The sliding plates 33 can drive the moving roller 22 downward. The pressing part includes an electric cylinder 32. The straightening frame 1 includes... The upper plate 12 is included, and the electric cylinder 32 is vertically installed on the top of the upper plate 12. The output rod of the electric cylinder 32 passes through the upper plate 12 and points downward. The output rod of the electric cylinder 32 cannot drive the slide plate 33 to move upward. An elastic rubber pad is fitted on the side of the electric cylinder 32 output rod facing the moving roller 22. The spring 34 and the elastic rubber pad below the electric cylinder 32 output rod can reduce the impact of the internal thread rod of the electric cylinder 32 caused by the rolling of the steel column, thus extending its service life. The inlet and outlet 111 can hold the steel column that needs to be corrected. The lower roller 21, the moving roller 22, and the side roller 23 clamp the steel column from four sides to fix it. The lower roller 21, the moving roller 22, and the side roller 23 are in contact with the steel column to achieve correction. The cross section of the inlet and outlet 111 intersects with the lower roller 21 and the side roller 23 respectively, which facilitates the feeding and discharging of materials at the inlet and outlet 111.

[0023] Please see Figures 1-4In this embodiment, the correction frame 1 also includes a side plate 11 located at the bottom of the upper plate 12. The side plate 11 is connected to the upper plate 12 by high-strength bolts. The side plate 11 has an opening 113 near the upper plate 12. A column 1131 is provided on the side of the opening 113 facing the upper plate 12. A movable plate 31 that can move along the axis of the column 1131 is provided on the column 1131. The movable plate 31 has a sliding hole 311 corresponding to the column 1131. An elastic rubber pad sleeved on the output rod of the electric cylinder 32 can contact the movable plate 31. The side plate 11 and the upper plate 12 are connected by high-strength bolts. 2. To increase the robustness of the equipment, high-strength bolts of grade 10.9 are used to ensure that the seismic fortification intensity of the device reaches six to eight degrees. The column 1131 can restrict the movement direction of the moving plate 31. A spring 34 is fitted on the column 1131 between the opening 113 and the moving plate 31. The spring 34 can lift the moving plate 31 and spring it up. When the electric cylinder 32 is retracted, it is convenient for the inlet and outlet 111 to feed and discharge materials. The opening 113 is also provided with a downwardly extending groove 1132. A sliding plate 33 is provided at the bottom of the moving plate 31 corresponding to the position of the groove 1132. The sliding plate 33 can... The slide plate 11 is capable of moving within the chute 1132. A rotating hole 112 is provided on the side plate 11. Rotating shafts 211 are provided on both sides of the lower roller 21, the moving roller 22, and the side roller 23 along their axial directions. The rotating shafts 211 of the lower roller 21 and the side roller 23 can pass through the rotating hole 112, and the rotating shaft 211 of the moving roller 22 can pass through the rotating hole 331. The chute 1132 restricts the movement and lowering of the slide plate 33, preventing the moving roller 22 from shifting and causing its axis to be non-parallel to the axes of the lower roller 21 and the side roller 23. The axial deviation of the lower roller 21, the moving roller 22, and the side roller 23 is less than or equal to ten millimeters. Gear 1 212 is mounted on the rotating shaft 211 on one side. On the side plate 11 near gear 1 212, motor 1 24 is mounted on the side away from gear 1 212. Gear 2 241 is mounted on the output shaft of motor 1 24. Gear 1 212 and gear 2 241 are connected by chain 25. The accuracy of steel column straightening is ensured by the axial deviation of lower roller 21, moving roller 22 and side roller 23 being less than or equal to 10 mm, and the steel column is prevented from bending. Only motor 1 24 drives lower roller 21 to rotate, so that side roller 23 and moving roller 22 rotate passively, reducing the number of motors 1 24.

[0024] Please see Figures 2-5In this embodiment, the perpendicularity of the lower roller 21 and the side roller 23 to the side plate 11 is less than or equal to one-thousandth of the height of the lower roller 21. By ensuring that the lower roller 21 and the side roller 23 are perpendicular to the side plate 11, the steel structure can be accurately clamped, preventing the straightness of the steel column after correction. The perpendicularity of the moving roller 22 to the sliding plate 33 is less than or equal to one-thousandth of the height of the moving roller 22. By ensuring that the moving roller 22 is perpendicular to the sliding plate 33, the straightness of the steel column can be accurately corrected after the moving roller 22 moves down.

[0025] During operation, the previous station or a worker inserts the steel column through the inlet / outlet 111 into the equipment. Simultaneously, the electric cylinder 32 is activated, causing the output rod of the electric cylinder 32 to press down, pushing the moving plate 31 downward. At this time, the spring 34 is compressed, and the slide plate 33 slides downward in the slide groove 1132, driving the moving roller 22 to press the steel column. At this time, the lower roller 21, the moving roller 22, and the side roller 23 are tangential to the steel column to achieve clamping. Then, the motor 24 is activated, which causes the gear 241 to rotate. Through the chain 25, the gear 212 is driven to rotate together, and the lower roller 21 also begins to rotate. Since the lower roller 21, the moving roller 22, and the side roller 23 are in close contact with the steel column, the lower roller 21, the moving roller 22, and the side roller 23 rotate together to achieve the function of clamping and straightening.

[0026] Through the above steps, the elastic rubber pads under the spring 34 and the output rod of the electric cylinder 32 can reduce the impact of the rolling of the steel column on the internal thread rod of the electric cylinder 32, thus extending its service life. The inlet and outlet 111 can hold the steel column that needs to be corrected. The lower roller 21, the moving roller 22, and the side roller 23 clamp the steel column from four sides to fix it. The lower roller 21, the moving roller 22, and the side roller 23 fit against the steel column to achieve correction. The cross-section of the inlet and outlet 111 intersects with the lower roller 21 and the side roller 23 respectively, which facilitates the feeding and discharging of materials at the inlet and outlet 111. This solves the problem that the existing device cannot correct the steel column. In the process of correcting the steel structure, the rigidity of the movement of the uneven parts of the steel structure is transmitted to the lead screw, which can easily damage the lead screw of the adjustment structure.
