Description

Technical Field

[0001] The present invention belongs to the technical field of mooring chain welding, and particularly relates to a mooring chain welding machine with a preheating tooling. Background Art

[0002] Mooring chains are essential key components in important marine equipment such as ships, offshore platforms, and port facilities. They are mainly used to fix the positions of ships or platforms. Mooring chains are usually made of high-strength steel, and their manufacturing process requires extremely high precision and quality to ensure good load-bearing capacity, corrosion resistance, and wear resistance during use. In the manufacturing process of mooring chains, welding is one of the most critical processes. During the welding process, the welded parts need to have sufficient strength, toughness, and corrosion resistance to ensure the long-term stable use of mooring chains. During the welding of the cross bars in the middle of mooring chains, due to the temperature change in the welding area and the contact of different materials, problems may occur in the performance of the welded metal. Especially when welding high-strength steel, cracks, welding defects, etc. are likely to occur in the welded parts, thus affecting the welding quality and the overall performance of mooring chains. Therefore, in order to improve the welding quality and avoid welding defects, the preheating technology has emerged. During the welding of high-strength steel, too large a temperature difference in the welded parts will cause phenomena such as cracks and stress concentration during welding, affecting the welding quality. Preheating can effectively reduce the thermal gradient during welding, reduce the stress and thermal deformation generated during welding, prevent the material from cooling prematurely, and make the temperature of the welded metal and the base material closer, thereby reducing the risk of welding defects. Summary of the Invention

[0003] The purpose of the present invention is to ensure the firm and stable clamping of the mooring chain during the welding process through the coordinated action of the moving clamping device and the first and second clamping and welding devices, enabling the mooring chain to be accurately positioned during the welding process, avoiding welding deviation or unevenness. The heating device can preheat the mooring chain before welding to ensure that the metal material during the welding process remains within an appropriate temperature range, thereby improving the welding quality and reducing stress concentration, and avoiding problems such as welding defects.

This design not only avoids the influence of impurities on the welding quality, but also reduces the workload of subsequent cleaning and improves the production efficiency;

[0017] 4. The cooling design of the mobile clamping device and the welding head (through the air blowing cooling port) can effectively cool down, prevent the equipment from overheating, and extend the service life of the welding machine. In addition, the temperature control design of the clamping device enables the equipment after welding to cool down in time, thus avoiding the damage to the equipment caused by high temperature;

[0042] During operation, in the initial working state of the system, the lifting ceiling 1 first performs vertical lifting through the motor lifting device 13 to adjust the height for processing the mooring chain. The motor rotating hanging disc device 15 drives the rotation and connection of the mooring chain conveying device 16 to move the mooring chain above the heating device. The heating device 4 pre-heats the mooring chain through the burner 44 in the refractory box 42. In this process, the high-temperature gas is guided to the surface of the mooring chain through the evenly distributed second connecting pipe 43 to provide suitable temperature conditions for welding. The refractory box can withstand high temperatures to ensure safety and efficiency during the heating process. After heating, the mooring chain rotating conveying device 2 is responsible for driving the mooring chain to be transported horizontally. This device drives the mooring chain to rotate and move smoothly within the clamping device through an electric drive system, so as to ensure that the mooring chain can accurately reach the predetermined welding position. After the mooring chain reaches the welding area, the moving clamping device 3 adjusts its position through the moving device 32 to ensure that the clamping device can accurately clamp the mooring chain. The moving device 32 drives the slider 326 on the slide rail 325 through the rotating motor 322 and the lead screw 323 to achieve precise control of the clamping device. The first clamping and welding device 33 and the second clamping and welding device 34 provide support for completing the welding task. The first clamping and welding device 33 adjusts its clamping force and position through the first telescopic cylinder 332 to ensure the stability of the mooring chain. The second clamping and welding device 34 continues to accurately clamp the mooring chain to ensure that the welding process is not interfered. Each first clamping head 3351 and second clamping head 3451 provides precise welding head positioning through the motor-driven lead screw system to ensure the welding position and quality. During the welding process, the cleaning device 35 regularly removes the residues and welding slag on the welding fixture through the air jet head 353 to avoid the influence of these impurities on the welding quality. The design of the U-shaped support frame 351 and the air jet head 353 enables effective removal of these impurities to ensure the smooth progress of the welding process. After the clamping device precisely fixes the mooring chain, the first welding head 3356 and the second welding head 3456 perform precise forward and backward, up and down movements through the longitudinal and transverse lead screw motor moving devices of the control system to ensure the accuracy of welding. The automatic adjustment function of the welding head can adjust the welding depth and angle according to needs, thus ensuring the welding quality. After welding, the air blowing cooling port 312 on the clamping device cools the welding part quickly through air flow to prevent welding defects caused by overheating. The cooling process ensures the stability of the welded mooring chain. After welding and cooling, the completed mooring chain is transported to the final position by the conveying device, ready for the next step of processing or transportation.
