DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4As shown, the utility model provides a cooling device, which includes a first shell 1, a normal temperature water tank 5 and a constant temperature water tank 6 are fixedly installed inside the first shell 1, and the constant temperature water tank 6 includes a cooling device, a heating resistor and a temperature sensor head. A control panel 10 is installed on the outer surface of the first shell 1, a processing table 3 is fixedly installed on the top of the first shell 1, and a second pipeline 33 is buried inside the processing table 3. A first pipeline 4 is fixedly installed inside the second shell 2, and the input end of the first pipeline 4 is fixedly installed on the output end of the second pipeline 33. The second shell 2 Two first fans 21 are installed on the side of the interior away from the first shell 1, and an air inlet 22 is between the second shell 2 and the first shell 1. The output end of the first pipe 4 is fixedly installed on the normal temperature water storage tank 5, and the second pipe 33, the first pipe 4, and the normal temperature water storage tank 5 are connected in sequence. A water pump 9 is fixedly installed on the upper surface of the constant temperature water storage tank 6, and the input end of the water pump 9 is connected to the interior of the constant temperature water storage tank 6 through a pipe, and the output end of the water pump 9 is connected to the input end of the second pipe 33 through a pipe, and the constant temperature water storage tank 6, the water pump 9, and the second pipe 33 are connected in sequence.

[0023] The welding temperature directly affects the quality and strength of the weld. If the welding temperature is too high or too low, the weld quality will be reduced. During the welding process, too high a temperature will cause the weld to overheat, resulting in excessive growth of metal grains, thereby significantly reducing the strength of the weld. Too low a temperature will easily cause cold cracking of the weld, thereby reducing the strength and toughness of the weld. Therefore, choosing an appropriate welding temperature is very important for weld quality.

[0024] Most traditional cooling devices use coolant circulation for cooling, and cool the coolant through the external room temperature before cooling the workpiece. This method will cause the coolant temperature to be too low when the external ambient temperature is low, causing the weld to cool down suddenly. The large temperature difference can easily cause cracks in the weld joint, thus affecting the overall welding quality. When the device is working, the water pump 9 will transport the constant temperature water inside the constant temperature water tank 6 to the second pipe 33. The second pipe 33 takes away the temperature of the workpiece surface and is driven to circulate into the first pipe 4. At this time, the first fan 21 works, sucking in the external normal temperature air from the air inlet 22 and then blowing it out from the other side. The first pipe 4 is set in a spiral shape, so that the first pipe 4 can quickly cool to room temperature, and then be driven by the water pump 9 to enter the normal temperature water tank 5. At this time, the inside of the normal temperature water tank 5 What is stored is room temperature liquid. Then, under the continuous operation of water pump 9, the room temperature liquid inside normal temperature water storage tank 5 will enter the interior of constant temperature water storage tank 6. The temperature sensing head can sense the real-time temperature inside constant temperature water storage tank 6. When the temperature is lower than the set temperature, the heating resistance wire works to heat the interior of constant temperature water storage tank 6. When the temperature is higher than the set temperature, the cooling device works to lower the temperature inside constant temperature water storage tank 6. After many tests, it is known that the welding seam cooling effect is best when the coolant temperature is 20℃-25℃. Therefore, a normal temperature water storage tank 5 and a constant temperature water storage tank 6 are set to avoid the sudden cooling of the weld caused by the excessively low temperature of the coolant, and the weld will not crack coldly. While ensuring the cooling effect, the cooling is also made more stable, the occurrence of defective products is reduced, product quality is improved, and material waste is reduced.

[0025] A plurality of evenly distributed air outlet holes 31 are provided at one end of the processing table 3, a plurality of evenly distributed air suction holes 32 are provided at one end of the processing table 3 away from the air outlet holes 31, the output end of the normal temperature water storage tank 5 is fixedly connected to the input end of the constant temperature water storage tank 6, a second bucket-shaped pipe 8 is fixedly installed on the side of the lower surface of the processing table 3 close to the air outlet holes 31, and the second bucket-shaped pipe 8 is connected to the plurality of air outlet holes 31, a first bucket-shaped pipe 7 is fixedly installed on the side of the lower surface of the processing table 3 close to the air suction holes 32, and the first bucket-shaped pipe 7 is connected to the plurality of air suction holes 32.

[0026] A plurality of third pipes 71 are fixedly installed on the lower surface of the first bucket-shaped pipe 7, a suction assembly 72 is provided below the first bucket-shaped pipe 7, the plurality of third pipes 71 are all fixedly installed on the suction assembly 72, the plurality of third pipes 71 are all connected to the interior of the suction assembly 72, a plurality of fourth pipes 73 are installed below the suction assembly 72, the plurality of fourth pipes 73 are all connected to the interior of the suction assembly 72.

[0027] A plurality of fifth pipes 81 are fixedly installed on the lower surface of the second bucket-shaped pipe 8, an air supply assembly 82 is provided below the second bucket-shaped pipe 8, the plurality of fifth pipes 81 are all fixedly installed on the air supply assembly 82, the plurality of fifth pipes 81 are all connected to the interior of the air supply assembly 82, a plurality of sixth pipes 83 are fixedly installed below the air supply assembly 82, the plurality of sixth pipes 83 are all connected to the interior of the air supply assembly 82.

[0028] The air suction assembly 72 and the air supply assembly 82 both include a first main pipe 721, a filter plate 722 is fixedly mounted at the bottom end of the first main pipe 721, a second fan 723 is fixedly mounted at the bottom end of the filter plate 722, and a second main pipe 724 is fixedly mounted at the bottom end of the second fan 723.

[0029] A seventh pipe 84 is connected to the lower part of the sixth pipe 83 . One end of the seventh pipe 84 away from the sixth pipe 83 is connected to the corresponding fourth pipe 73 . The seventh pipe 84 is located inside the constant temperature water storage tank 6 .

[0030] In actual use, the device is installed inside the welding chamber of the laser welding machine. When the laser welding is working for a long time, the internal temperature of the welding chamber will rise, which may cause the weld to cool slowly and cause unstable welding. If the environment is too cold, it will take a long time to warm up the laser welding, which will not only affect the welding efficiency, but also cause poor welding permeability and substandard welding quality. When using the device, the suction component 72 works to absorb the gas inside the welding chamber through the air outlet 31 and the third pipe 71, and then discharge it to the inside of the seventh pipe 84 through the fourth pipe 73, because the seventh pipe 84 is located inside the constant temperature water storage tank 6, and there are multiple seventh pipes 84. The seventh pipe 84 can quickly drop to a constant temperature state. The air supply component 82 will absorb the constant temperature gas inside the seventh pipe 84 through the sixth pipe 83, and transport it to the inside of the welding bin through the fifth pipe 81 and the air outlet 31, so that the temperature inside the welding bin is always kept constant. Therefore, by setting the suction component 72 and the air supply component 82, the device can keep the temperature inside the welding bin at a constant temperature, reduce the impact of the environment on welding, and use water cooling and air cooling to reduce the temperature, so that the cooling efficiency is higher, thereby increasing the output.

[0031] Using a cooling device and a heating resistor wire can perform water cooling and air cooling at the same time, reducing the demand for refrigeration and heating devices, making the manufacturing cost of the cooler lower and able to adapt to the actual needs of more companies.
