Description

Technical Field

[0001] The present invention relates to the technical field of metal chain welding, in particular to a metal chain welding device with a winding structure and a use method thereof. Background Art

[0002] Traditional welding relies on manual labor, which is susceptible to skill differences and leads to inconsistent quality. Metal chains, as transmission or load-bearing components, require extremely high welding strength and sealing. The increasing demand for lightweight chains in fields such as aerospace and automobiles has driven the upgrading of welding processes for high-strength steel and alloy materials. In addition, metal chains contain special-shaped chains and multiple welding points, which makes it difficult for traditional equipment to cover all angles, thus promoting the development of new welding equipment.

[0003] During the winding process of the metal chain after welding, the thermal stress and welding residue inside the metal chain will affect the winding process. The superposition of residual stress during winding and bending will cause stress concentration. The welding residue will scratch the surface of the metal chain during winding, reducing the quality of the metal chain.

[0004] Patent CN117506210B discloses an automatic welding device for ship anchor chains. The above patent improves the stability during the welding process while facilitating full contact between the horizontal axis and the metal ring.

[0005] The above patent sets two U-shaped plates one and two U-shaped plates two to cooperate with each other to limit the metal rings therein, so that the two adjacent metal rings are limited and fixed and remain parallel to the U-shaped plate one or the U-shaped plate two, which is convenient for placing the horizontal axis into the annular area of ​​the metal ring. While improving the stability during the welding process, it is convenient for the horizontal axis to maintain full contact with the metal ring, and makes the straight section of the horizontal axis and the metal ring perpendicular to each other, avoiding the smaller contact area between the metal ring and the horizontal axis due to the offset of the metal ring, which in turn leads to lower overall strength of the metal ring after welding. There is room for optimization in stress removal after metal chain welding.

[0006] To this end, the present application proposes a metal chain welding device with a winding structure for eliminating residual stress in the metal chain and a method for using the same. Summary of the Invention

[0053] The stress assembly includes: a vibrator 8, a heating box 9, a cooling box 10, a temperature sensor 11, a heater 12 and a cooling unit;

[0054] A heating box 9 is installed at the output end of the conveyor belt 3, a cooling box 10 is installed on the right side of the outer wall of the heating box 9, a vibrator 8 is installed on the lower side of the inner wall of the heating box 9 and the cooling box 10, heaters 12 are installed on the front and back sides of the inner wall of the heating box 9, temperature sensors 11 are installed on the left and right sides of the inner wall of the heating box 9, and cooling units are installed on the front and back sides of the inner wall of the cooling box 10. The vibrator 8, heater 12 and cooling unit are connected to the winding motor 7 through a connecting shaft, and the temperature sensor 11 is connected to the controller 2 through a signal line;

[0055] The cooling unit includes: a fan 31, a heat exchange chamber 32 and a heat exchange valve 33;

[0056] A heat exchange chamber 32 is installed on the lower side of the outer wall of the cooling box 10, a temperature sensor 11 is installed in the middle of the inner wall of the heat exchange chamber 32, a fan 31 is installed on the lower side of the outer wall of the heat exchange chamber 32, the fan 31 is connected to the winding motor 7 through a connecting shaft, and the fan 31 is connected to the switching valve 28 through a connecting pipe. Heat exchange valves 33 are installed on the upper and lower sides of the outer wall of the heat exchange chamber 32, and the heat exchange chamber 32 is connected to the heating box 9, the water tank 18 and the preheating box 30 through the heat exchange valve 33;

[0057] Furthermore, after the metal chain is welded, the conveying motor 4 drives the conveyor belt 3 to convey the metal chain into the heating box 9. The controller 2 controls the heater 12 to heat the inside of the heating box 9. The temperature inside the heating box 9 is collected by the temperature sensor 11 inside the heating box 9. The initial temperature is raised to 250℃~350℃ and kept warm for 30min~60min. Then, the heater 12 is controlled to raise the temperature inside the heating box 9 to 550℃~650℃ and kept warm for 60min~90min. Finally, the heating box 9 and the water tank 18 are connected through the heat exchange valve 33 to reduce the temperature inside the heating box 9 by 400℃~500℃. 0℃ to keep warm for 45min~60min, when the metal chain enters the heating box 9 for heat treatment to remove residual stress in three temperature stages, the controller 2 controls the vibrator 8 inside the heating box 9 to generate different vibration frequencies according to different temperature stages to assist in removing residual stress of the metal chain.

After completing the heat treatment, the conveyor belt 3 moves the metal chain to the heating box 9 for heat treatment. The metal chain is sent into the cooling box 10 for cooling. The controller 2 controls the winding motor 7 to drive the fan 31 to rotate through the heat exchange valve 33 to connect the heating box 9 and the water tank 18. The heat in the heating box 9 is absorbed by the water flow heat exchange and converted into the wind generated by the rotation of the fan 31, so that the temperature of the wind blown into the cooling box 10 by the fan 31 increases. In the process of cooling the metal chain, the temperature of the cooling wind is adjusted by gradient, and the temperature change rate of the cooling wind is controlled within 150℃ / h. While the cooling wind cools the metal chain, the controller 2 controls the winding motor 7 to drive the vibrator 8 inside the cooling box 10 to vibrate at a frequency of 20Hz~50Hz. The rate of vibration is reduced to avoid stress generated inside the metal chain during the cooling process. After the metal chain is cooled and cleaned, the controller 2 controls the alignment roller 5 to adjust the angle of the metal chain to be consistent. Then the metal chain is wound under the action of the take-up roller 6 driven by the winding motor 7, thereby achieving the function of eliminating the residual stress of the metal chain and solving the problems of incomplete stress elimination, cold cracking risk and high winding damage rate. The residual stress inside the metal chain can be removed in a coordinated manner through heat treatment, vibration treatment and cooling treatment, thereby avoiding damage to the metal chain during winding and storage due to residual stress, improving the quality of the metal chain and improving the economic benefits of the device.

[0064] Furthermore, after the metal chain is cleaned, the controller 2 controls the conveying motor 4 to drive the conveyor belt 3 to convey the metal chain into the preheating box 30. Before conveying the metal chain into the preheating box 30, the visual sensor 13 collects information about the metal chain and transmits the information to the controller 2. The controller 2 identifies the material, size and other information of the metal chain based on the collected information. After the metal chain enters the preheating box 30, the controller 2 heats the metal chain to the corresponding temperature according to the type of the metal chain and continues to convey it forward. When it is conveyed to the fixer 14, the controller 2 controls the welding motor 17 to drive the telescopic rod 15 to push the fixer 14 so that the fixer 14 contacts the metal chain and generates pressure on the metal chain to fix the metal chain.

Then the controller 2 controls the conveying motor 4 to drive the slider 40 to move in the chute 39 to convey the metal chain. During the conveying process of the metal chain, the cleaning brush 19 and the grinding head 20 located above the chute 39 clean the metal chain under the action of the movable shaft 21 driven by the conveying motor 4. Before the cleaned metal chain is conveyed to the input end of the conveyor belt 3, the controller 2 controls the conveying motor 4 to drive the push rod 36 to move, and the metal chain is conveyed to the input end of the conveyor belt 3. The movable piston 35 moves back and forth in the pressurized chamber 34 to extract the water flow in the water tank 18 and then spray it out from the nozzle 24 to remove the residual cleaning liquid and impurities on the metal chain. During the movement of the piston 35, the balance pipe 37 is used to maintain the internal pressure of the pressurized chamber 34 stable. After the metal chain is welded, it enters the cleaning tank 22 from the cooling box 10, and is clamped by the supporting component. After the metal chain is cleaned, it is transported to the alignment roller 5 for winding of the metal chain, realizing the function of automatic cleaning of the metal chain, solving the problems of poor cleaning effect of the metal chain affecting the welding effect, low cleaning efficiency and deformation and wear of the metal chain during the cleaning process, and being able to quickly remove the oxide layer on the surface of the metal chain, thereby improving the cleaning efficiency and welding effect of the metal chain and reducing the possibility of cleaning wastewater polluting the environment.

[0075] A preheating box 30 is installed on the left side of the outer wall of the holder 14, and the preheating box 30 is connected to the heating box 9 through a connecting pipe. A protective cover 26 is installed on the right side of the outer wall of the holder 14, and a welding head 25 is installed on the upper part of the inner wall of the protective cover 26.

[0076] The cooling unit includes: a fan 31, a heat exchange chamber 32 and a heat exchange valve 33;

[0077] A heat exchange chamber 32 is installed on the lower side of the outer wall of the cooling box 10, a temperature sensor 11 is installed in the middle of the inner wall of the heat exchange chamber 32, a fan 31 is installed on the lower side of the outer wall of the heat exchange chamber 32, the fan 31 is connected to the winding motor 7 through a connecting shaft, and the fan 31 is connected to the switching valve 28 through a connecting pipe.

[0078] Furthermore, during the metal chain welding process, the welding head 25 generates a large amount of heat, which is connected to the water tank 18 through the circulation pipe 29 via the connecting pipe to exchange the heat generated by the welding head 25 to prevent the welding head 25 from being damaged due to excessive temperature. The water after heat exchange enters the water tank 18, and the preheating box 30 is connected to the heating box 9 through the connecting pipe.

After the heat exchange, the hot air is detected by the temperature sensor 11. When the cooling air temperature of the set gradient is reached, it is passed into the cooling box 10 to cool the metal chain. When flushing the metal chain, normal temperature water may not achieve the flushing effect. The hot water after heat exchange can improve the flushing effect of the metal chain, realize the function of multi-level utilization of thermal energy, solve the problems of thermal energy dissipation, poor metal chain cleaning effect and too fast cooling rate, can reduce heat loss, improve energy utilization, reduce the production cost of the device, increase the service life of the device, and improve the metal chain cleaning effect.

[0079] Example 5: Please refer to Figure 1 、 Figure 2 and Figure 3 A metal chain welding device with a winding structure includes a base 1 and a winding module. A controller 2 is installed on the front side of the outer wall of the base 1, and the winding module is installed on the right side of the outer wall of the base 1. A conveyor belt 3 is installed at the input end of the winding module. A conveying motor 4 is installed in the middle of the inner wall of the base 1. The conveyor belt 3 is connected to the conveying motor 4 through a connecting shaft. The winding module and the conveying motor 4 are connected to the controller 2 through a signal line.

[0080] The winding module includes: an alignment roller 5, a take-up roller 6, a winding motor 7 and a stress component;

[0081] The output end of the conveyor belt 3 is equipped with a stress component, an alignment roller 5 is installed on the right side of the outer wall of the stress component, a take-up roller 6 is installed on the right side of the outer wall of the alignment roller 5, and a winding motor 7 is installed on the right side of the inner wall of the base 1. The alignment roller 5 and the take-up roller 6 are respectively connected to the winding motor 7 through a connecting shaft, and the winding motor 7 is connected to the controller 2 through a signal line;

[0082] The input end of the conveyor belt 3 is equipped with a visual sensor 13, which is connected to the welding module via a signal line. The welding module includes: a fixer 14, a telescopic rod 15, a rotating shaft 16, a welding motor 17 and a welding assembly;

[0083] A holder 14 is installed on the right side of the outer wall of the visual sensor 13. The holder 14 is 1 / 4 circular. A telescopic rod 15 is installed in the middle of the outer wall of the holder 14. Rotating shafts 16 are installed at both ends of the telescopic rod 15. A welding motor 17 is installed in the middle of the inner wall of the base 1. The telescopic rod 15 and the rotating shaft 16 are respectively connected to the welding motor 17 through connecting shafts. The welding motor 17 is connected to the controller 2 through a signal line.

[0084] Furthermore, during the welding process of the metal chain, a part of the metal chain is welded, and the controller 2 controls the winding motor 7 to drive the alignment roller 5 and the take-up roller 6 to rewind the metal chain. The other part of the metal chain is on the conveyor belt 3 waiting for welding. The controller 2 controls the welding motor 17 to drive the telescopic rod 15 to push the fixer 14 to fix the metal chain to be welded. Then the controller 2 controls the winding motor 7 to clamp the take-up roller 6 to rotate speed so that the metal chain is in a taut state. Then the welding assembly is controlled to weld the metal chain. After the welding is completed, the controller 2 controls the welding motor 17 to drive the telescopic rod 15 to move to cancel the fixation of the metal chain by the fixer 14. The conveying motor 4 drives the conveyor belt 3 and conveys the metal chain with the help of the winding motor 7 driving the take-up roller 6 to pull the welded metal chain. After the metal chain to be welded enters the welding assembly, the operation is repeated to make the metal chain being welded in a stretched state. By controlling the speed of the take-up roller 6 to adjust the speed of the take-up roller 6 by controlling the winding motor 7, the synergistic tension between the fixer 14 and the take-up roller 6 is between 2% and 5% of the yield strength of the metal chain, so that the metal chain fits tightly, reducing the fluctuation of the butt gap, and offsetting the thermal shrinkage stress generated during the welding process by stretching, so that the size deviation of the welded metal chain is smaller, thereby improving the yield rate of the finished metal chain.

[0085] Working principle: the operator puts the metal chain to be welded into the cleaning tank 22 at the input end of the conveyor belt 3, and the controller 2 controls the conveying motor 4 to drive the power rod 41 to push the clamping block 38 out to clamp the metal chain. The metal chain is immersed in the cleaning liquid in the cleaning tank 22, and the controller 2 controls the ultrasonic unit 23 to emit ultrasonic waves into the cleaning tank 22 to clean the metal chain. Then the controller 2 controls the conveying motor 4 to drive the slider 40 to move in the chute 39 to convey the metal chain. During the metal chain conveying process, the cleaning brush 19 and the grinding head 20 located above the chute 39 clean the metal chain under the action of the movable shaft 21 driven by the conveying motor 4. Before the cleaned metal chain is conveyed to the input end of the conveyor belt 3, the controller 2 controls the conveying motor 4 to drive the push rod 36 to move, and drives the piston 35 to make a reciprocating motion in the pressurized chamber 34 to extract the water flow in the water tank 18 and spray it out from the nozzle 24 to remove the residual cleaning liquid and impurities on the metal chain. During the movement of the piston 35, the balance pipe 37 is used to maintain the internal pressure of the pressurized chamber 34 stable.

[0086] After the metal chain is cleaned, the controller 2 controls the conveying motor 4 to drive the conveyor belt 3 to convey the metal chain into the preheating box 30. Before conveying the metal chain into the preheating box 30, the visual sensor 13 collects information about the metal chain and transmits the information to the controller 2. The controller 2 identifies the material, size and other information of the metal chain based on the collected information. After the metal chain enters the preheating box 30, the controller 2 heats the metal chain to the corresponding temperature according to the type of the metal chain and continues to convey it forward. When it is conveyed to the fixer 14, the controller 2 controls the welding motor 17 to drive the telescopic rod 15 to push the fixer 14 so that the fixer 14 contacts the metal chain and generates pressure on the metal chain to fix the metal chain. When the visual sensor 13 detects that the metal chain fixed by the fixer 14 is sliding, the controller 2 controls the welding motor 17 to drive the rotating shaft 16 at the connection between the fixer 14 and the telescopic rod 15 to rotate, thereby fixing the metal chain. The angle of the fixer 14 is adjusted so that the fixer 14 fits the contact surface of the metal chain, and then the controller 2 controls the welding head 25 to weld the metal chain. When the angle of the metal chain needs to be adjusted, the controller 2 controls the welding motor 17 to drive the rotating shaft 16 at the other end of the telescopic rod 15 to rotate, and adjust the angle of the metal chain so that the welding head 25 can weld metal chains with complex angles. When inert gas is needed to protect the metal chain welding, the controller 2 controls the switching valve 28 to connect the gas box 27 and the protective cover 26, and selects a suitable inert gas according to the type of metal chain collected by the visual sensor 13. After the welding is completed, the fan 31, the protective cover 26 and the switching valve 28 are connected. Driven by the winding motor 7, the fan 31 generates suction, and the inert gas in the protective cover 26 and the gas generated during welding are sucked into the space in the gas box 27 for storing the mixed gas;

[0087] After the metal chain is welded, the conveying motor 4 drives the conveyor belt 3 to convey the metal chain into the heating box 9, and the controller 2 controls the heater 12 to heat the inside of the heating box 9. The temperature inside the heating box 9 is collected by the temperature sensor 11 inside the heating box 9. The initial temperature is raised to 250℃~350℃ and kept warm for 30min~60min. Then the heater 12 is controlled to raise the temperature inside the heating box 9 to 550℃~650℃ and kept warm for 60min~90min. Finally, the heating box 9 and the water tank 18 are connected through the heat exchange valve 33 to reduce the temperature inside the heating box 9 by 400℃~500℃ to keep warm for 45min~60min. When the metal chain enters the heating box 9 for heat treatment to remove residual stress in three temperature stages, the controller 2 controls the vibrator 8 inside the heating box 9 to generate different vibration frequencies according to different temperature stages to assist in removing residual stress of the metal chain. In the 250℃~350℃ stage, the vibrator 8 vibrates The vibration frequency is 20Hz~40Hz, the vibration frequency of the vibrator 8 in the 550℃~650℃ stage is 50Hz~100Hz, and the vibration frequency of the vibrator 8 in the 400℃~500℃ stage is 30Hz~60Hz. After the heat treatment is completed, the conveyor belt 3 sends the metal chain into the cooling box 10 for cooling. The controller 2 controls the winding motor 7 to drive the fan 31 to rotate through the heat exchange valve 33 to connect the heating box 9 and the water tank 18. The heat in the heating box 9 is absorbed by the water flow heat exchange and converted into the wind generated by the rotation of the fan 31, so that the temperature of the wind blown into the cooling box 10 by the fan 31 increases. In the process of cooling the metal chain, the temperature of the cooling wind is adjusted by gradient, so that the temperature change rate of the cooling wind is controlled within 150℃ / h. While the cooling wind cools the metal chain, the controller 2 controls the winding motor 7 to drive the vibrator 8 inside the cooling box 10 to vibrate at a frequency of 20Hz~50Hz to avoid stress inside the metal chain during the cooling process.

[0088] After the metal chain completes stress relief and enters the cleaning tank 22 from the cooling box 10, the controller 2 controls the alignment roller 5 to adjust the angle of the metal chain to be consistent, and then the metal chain completes the winding work under the action of the receiving roller 6 driven by the winding motor 7.
