Description

Technical Field

[0001] The utility model relates to the technical field related to stress elimination, in particular to a device for eliminating residual stress in steel structures. Background Art

[0002] During the manufacturing and processing of steel structures, operations such as welding, cutting, and cold working will inevitably generate residual stress inside the components. These residual stresses may cause deformation, cracking, and reduced fatigue life of the steel structure, seriously affecting the safety and reliability of the steel structure. Residual stress elimination of steel structures is to reduce or eliminate these harmful residual stresses through specific methods and techniques. Common elimination methods include thermal aging, vibration aging, and ultrasonic impact. Thermal aging heats and cools the steel structure to cause the atoms inside the material to rearrange, thereby reducing the residual stress. Vibration failure uses the energy of vibration to change the crystal structure inside the steel structure to achieve the purpose of eliminating residual stress. Impact applies high-frequency impact force on the surface of steel structure, causing local plastic deformation, thereby reducing residual stress. Adding an adjustment mechanism to the steel structure residual stress elimination equipment enables the equipment to flexibly adapt to various complex steel structure shapes and installation environments. The direction, angle and height of the equipment can be accurately adjusted to ensure that the stress elimination operation acts accurately on the target position, greatly improving the effect and efficiency of residual stress elimination. At the same time, the versatility and applicability of the equipment are enhanced. Whether it is at high altitude, narrow space or irregular steel structure, it can be easily operated, reducing the difficulty of construction and providing a stronger guarantee for the safety and stability of steel structure. Therefore, there is a special need for a steel structure residual stress elimination equipment.

[0003] However, the existing steel structure residual stress elimination equipment is very limited in its use angle, and there is no way to further eliminate local residual stress, and the clamping effect is not very good during the elimination process. Utility Model Content

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a steel structure residual stress elimination device, comprising a placement plate and a placement block, wherein the placement block is mounted on the upper surface of the placement plate, an adjustment mechanism is provided above the placement plate, and a clamping mechanism is provided above the placement plate;

[0006] The adjustment mechanism includes a first electric slide, a second electric slide, a third electric slide, a placement rack and a Hawken impact head. The first electric slide is installed on the upper surface of the placement block, the upper surface of the first electric slide is slidably connected to the second electric slide, one side surface of the second electric slide is slidably connected to the third electric slide, and one side surface of the third electric slide is slidably connected to the placement rack.

[0007] Preferably, a Hawking impact head is installed on the upper surface of the placement rack.

[0008] Preferably, the third electric slide is connected to the Hawking impact head via a placement frame to form a sliding structure.

[0009] Preferably, the first electric slides are provided in two groups and are symmetrically distributed.

[0010] Preferably, the clamping mechanism includes a motor, a connecting rod, a mounting plate, a cylinder, a telescopic rod and a rubber pad. The inner surface of the placement plate is fixedly connected to the motor, the upper surface of the motor is connected to the connecting rod, the upper surface of the connecting rod is fixedly connected to the mounting plate, the upper surface of the mounting plate is installed with a cylinder, and one side surface of the cylinder is connected to the telescopic rod.

[0011] Preferably, a rubber pad is attached to one side surface of the telescopic rod.

[0012] Preferably, the cylinders are provided in four groups and are symmetrically distributed.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: after the steel structure residual stress elimination device is placed on the mounting plate, the cylinder is started, and the cylinder drives the rubber pad to clamp the steel material through the extension and contraction of the connecting rod. This clamping method is stable and reliable, and can ensure that the steel material is firmly fixed in the specified position during the residual stress elimination process, and will not be displaced or shaken due to various forces in the elimination operation, providing a solid foundation for accurately eliminating residual stress. At the same time, the use of the rubber pad effectively avoids hard contact between the steel material and the clamping component, prevents damage to the surface of the steel material, and protects the steel material. The motor is started, and the motor drives the mounting plate to rotate through the connecting rod, so that the steel material can be fully The steel material is azimuthally processed by the Hawken impact head. This rotating design expands the processing range, ensures that all parts of the steel material can be fully relieved of residual stress, and improves the uniformity and comprehensiveness of the elimination effect. Start the first electric slide to drive the second electric slide to adjust forward and backward, and then start the second electric slide to drive the third electric slide to adjust up and down. Finally, the third electric slide drives the Hawken impact head through the placement rack to accurately locate different parts of the steel material. This multi-dimensional precise adjustment function can perform personalized operations according to the shape, size and residual stress distribution of the steel material, ensuring that the Hawken impact head can accurately act on the key parts that need to eliminate stress.
