Description

Technical Field

[0001] This utility model relates to the field of high-strength steel production technology, specifically to a device for deformation correction and reinforcement of high-strength steel structures. Background Technology

[0002] In the field of traditional high-strength steel structure deformation correction, existing technologies mainly rely on manual operation or semi-mechanized equipment, which suffer from core problems such as low correction efficiency, insufficient precision and automation, and poor equipment adaptability. Traditional heating methods (such as open flame baking) are difficult to control the temperature and range precisely, which can easily lead to overheating or uneven softening of materials, requiring repeated adjustments and taking a long time. Manual handling and positioning of steel can easily introduce errors, and mechanical extrusion devices lack dynamic pressure feedback, with correction force relying entirely on experience, which can easily cause secondary deformation or material damage. For deformation of high-strength steel (such as welding residual stress and impact deformation), traditional equipment is difficult to meet the needs of correction and reinforcement simultaneously due to low heating efficiency and uncontrollable extrusion force. In view of this, in-depth research was conducted to address the above problems, which led to this case. Utility Model Content

[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0016] Please see Figure 1-3 In the field of traditional high-strength steel structure deformation correction, existing technologies mainly rely on manual operation or semi-mechanized equipment, which have the following core problems: Low correction efficiency: Traditional heating methods (such as open flame baking) are difficult to control the temperature and range accurately, which can easily lead to overheating or uneven softening of materials, requiring repeated adjustments and taking a long time; Insufficient precision and automation: Manual handling and positioning of steel can easily introduce errors, and mechanical extrusion devices lack dynamic pressure feedback, and the correction force depends entirely on experience, which can easily cause secondary deformation or material damage. Therefore, this application protects a high-strength steel structure deformation correction and reinforcement device. The device uses a transport robotic arm on a structural support to move steel to multiple support wheels 13. The position of the steel is adjusted by the support wheels 13. A pair of lifting adjustment hydraulic push rods 11 inside a pair of lifting convex grooves 10 operate, driving concave lifting support bearing blocks 12. These concave lifting support bearing blocks 12 then drive the support wheels 13, thus changing the height of the steel. A pair of thermoplastic screw modules 3 operate, driving movable clamping blocks 4. These movable clamping blocks 4 drive two pairs of thermoplastic electric push rods 5, which simultaneously extend and retract, driving concave-shaped mounting blocks. Multiple semi-circular spiral metals on it are driven to extend and retract relative to each other through pairs of concave-shaped sleeve blocks. Through the contact of multiple semi-circular spiral metals, the contact conductor 8 is activated, thereby combining multiple semi-circular spiral metals into a threaded metal rod, thus generating an inductive heating effect. The steel is heated by a pair of moving concave-shaped sleeve blocks. Then, the extrusion sleeve block 14 is driven by two pairs of extrusion screw modules. The extrusion sleeve block 14 is extended and retracted by the extrusion electric push rod 17 on its inner side, which drives the convex extrusion block 16 on it. The convex extrusion block 16 drives the extrusion concave bearing block 19 on it. The extrusion concave bearing block 19 drives the extrusion wheel 18 on it, which extrudes and shapes the hot melt softening process. In summary, the process involves a robotic arm placing the steel onto support wheels 13, and adjusting the height of these wheels using a lifting hydraulic push rod to achieve initial positioning. Subsequently, a pair of hot-melt screw modules 3 drive the moving clamping block 4, which in turn moves the hot-melt electric push rod 5 to adjust the position of the concave fitting block. This causes the semi-circular spiral metal rod 7 to contact and combine into a threaded conductor. When the contact conductor 8 is energized, it generates an inductive effect, locally heating and softening the deformed area of ​​the steel. A pressure sensor monitors the contact pressure in real time to ensure uniform heating. After heating, two pairs of extrusion screw modules drive the extrusion wheel 18 closer to the softened area. The electric push rod controls the extrusion force, applying mechanical pressure to the deformed area for correction and shaping. The equipment can cycle through the heating-extrusion process until the steel returns to its designed shape and is reinforced. Its core principle lies in combining inductive heating technology (using threaded conductors to generate eddy currents to achieve rapid softening) with an electromechanical integrated control system (screw module, electric push rod and hydraulic system work together to control positioning and force). It achieves efficient and precise correction through a composite mechanism of "thermal melting and softening - mechanical extrusion". At the same time, it relies on pressure feedback to optimize parameters, ensuring that the correction process is efficient and avoids material damage.
