Description

Technical Field

[0001] This utility model relates to the field of steel profile production technology, and in particular to a top straightening device. Background Technology

[0002] In the fields of metal processing and machinery manufacturing, round tubes are widely used as important basic components in industries such as construction, automobiles, and aerospace. However, during transportation, storage, or preliminary processing, round tubes are highly susceptible to bending and deformation due to external forces, affecting their subsequent performance and assembly accuracy. Therefore, round tube straightening has become an indispensable and critical process.

[0003] Currently, the industry commonly uses hoisting methods to straighten bent circular tubes. This method primarily involves using cranes or other hoisting equipment to lift the bent tube, and then, with the aid of manual operation or simple tooling, repeatedly adjusting the bent portion of the tube using gravity and manually applied external force. This process not only consumes a significant amount of time for lifting, positioning, and adjusting the tube, but also only allows for straightening a single tube at a time, making batch processing difficult. Furthermore, hoisting straightening is highly dependent on the operator's experience and skill level; the tube's posture is difficult to control precisely during operation, resulting in low straightening efficiency and failing to meet the demands of modern large-scale industrial production. In addition, frequent hoisting operations pose safety hazards, increasing the risk factor in the production process, and the substantial investment of manpower and equipment resources further drives up production costs.

[0004] Currently, no effective solutions have been proposed for the problems of cumbersome operation, low correction efficiency, high safety risks, and high production costs in related technologies. Utility Model Content

[0161] The drive element 501 is activated, and the third abutment element 401 is driven by the transmission element 502 to gradually approach the bent part of the workpiece to be corrected.

[0162] While the third abutting element 401 abuts against the bent portion of the workpiece to be corrected, the driving element 501 continues to operate until the workpiece to be corrected is corrected.

[0163] When the workpiece to be corrected is corrected, stop the drive element 501 and maintain the current state for a preset time;

[0168] The technical effects of this utility model are as follows:

[0169] 1) Compared with traditional hoisting and straightening, there is no need for a complicated hoisting mechanism to transfer the workpiece. The input and output of the workpiece can be completed using a common conveying structure, which improves efficiency;

[0170] 2) It is simple and quick to operate, and can be applied to workpieces of different specifications to meet on-site production requirements.

[0171] Example 2

[0172] This embodiment is a modified embodiment of embodiment 1.

[0173] like Figure 8As shown, the top straightening device also includes a first adjustment unit 600, a second adjustment unit 700, and a third adjustment unit 800. The first adjustment unit 600 is connected to the frame unit 100 and the first abutment unit 200, respectively, and is used to adjust the position of the first abutment unit 200. The second adjustment unit 700 is connected to the frame unit 100 and the second abutment unit 300, respectively, and is used to adjust the position of the second abutment unit 300.

[0175] Furthermore, to prevent unforeseen circumstances, the first adjustment unit 600, the second adjustment unit 700, and the third adjustment unit 800 can be locked, such as by locking the adjustment structures of the first adjustment unit 600, the second adjustment unit 700, and the third adjustment unit 800 to prevent them from operating. This locking method is a conventional technical means in this field (such as mechanical locking methods, including but not limited to bolt locking, nut locking, blocking structures, and snap-fit ​​mechanisms), and will not be elaborated further here.
