Description

Technical Field

[0001] The utility model relates to the technical field of energy storage machine welding equipment, in particular to a transformer used for energy storage machine welding equipment. Background Art

[0002] The energy storage welding machine transformer is a pulse transformer with high power output. It is designed to cooperate with the energy storage welding machine for efficient and reliable welding operations. It is significantly different from the power frequency transformer used in other welding machines in structure and function. The working principle of the energy storage welding machine transformer is based on the instantaneous discharge of the capacitor bank. Before welding, the capacitor bank is charged by a rectifier to store electrical energy. During welding, the capacitor bank discharges the primary winding of the welding transformer to generate a high-energy pulse current. This pulse current is output through the secondary winding of the transformer and is used to weld the workpiece. Energy storage welding machine transformers are widely used in industrial fields that require high-quality and high-efficiency welding, such as automobile manufacturing, machinery manufacturing, aerospace, etc.

[0003] For example, the Chinese patent "Capacitor Energy Storage Welding Machine Transformer Structure" with announcement number CN202291816U includes several transformers, the secondary coils of the several transformers are connected in series in pairs and then in parallel as a whole, wherein the output ends of the secondary coils of the first transformer and the last transformer are connected to the secondary output copper busbar, and the secondary coils of two adjacent transformers among the several transformers are connected in series through the connecting copper busbar, and the transformer is a 500KVA energy storage discharge transformer.

[0004] Although the above-mentioned prior art can realize the discharge of the transformer, in actual use, on the one hand, the heat dissipation of the transformer is not timely enough, and the transformer will generate a large amount of heat during use, causing the generated heat to accumulate on the transformer body, thereby reducing the working performance of the transformer. On the other hand, the transformer is not convenient to move. When the welding equipment is moved, the transformer as a whole needs to be moved, resulting in the operator having to move the transformer every time the transformer is moved, thereby reducing the efficiency of the welding operation. Therefore, it does not meet the existing needs. In this regard, we propose a transformer for energy storage machine welding equipment. Utility Model Content

[0005] The utility model aims to provide a transformer for energy storage machine welding equipment to solve the problems of insufficient heat dissipation of the transformer and inconvenient movement of the transformer proposed in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a transformer for energy storage machine welding equipment, comprising a base, a transformer housing is fixedly arranged on the upper end of the base, and a cooling chamber is arranged above the inside of the transformer housing; and further comprising:

[0007] A liquid outlet pipe is arranged on one side of the outside of the transformer housing, and one end of the liquid outlet pipe is communicated with the cooling chamber, and a water pump is arranged at the other end of the liquid outlet pipe, and the water pump is communicated with the liquid outlet pipe;

[0008] The liquid inlet pipe is arranged on the other side of the transformer housing, and one end of the liquid inlet pipe is connected to the cooling chamber. The other end of the liquid inlet pipe and the other end of the water pump are fixedly provided with a liquid distributor, and the liquid distributor is respectively connected to the liquid inlet pipe and the water pump.

[0009] Preferably, a heat dissipation cavity is provided at the lower part of the transformer housing, five cooling tubes are equidistantly provided between the liquid distributing tubes on both sides, and the cooling tubes penetrate the heat dissipation cavity and are connected with the liquid distributing tubes.

[0010] Preferably, a motor is fixedly arranged inside the base, and the output shaft of the motor extends into the heat dissipation cavity, and fan blades are fixedly arranged outside the output shaft of the motor located inside the heat dissipation cavity, and the fan blades are located below the cooling pipe.

[0011] Preferably, a plurality of fixing rods are fixedly provided on the outside of the cooling tube, and the upper ends of the fixing rods are fixedly connected to the upper end of the heat dissipation cavity.

[0012] Preferably, a fixing seat is fixedly provided at each of the four corners of the lower end of the base, a mounting ear plate is provided at the lower end of the fixing seat, and the mounting ear plate is rotatably connected to the fixing seat.

[0013] Preferably, a connecting rod is fixedly provided inside the mounting ear plate, a pulley is provided outside the connecting rod, the pulley is rotatably connected to the connecting rod, and the lower end of the pulley is in contact with the ground.

[0014] Preferably, the front and rear ends of the upper outer end of the transformer shell are both provided with current ports, and the current ports are welded and fixed to the transformer shell, and the transformer body is fixedly provided inside the cooling cavity.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can extract the coolant in the cooling chamber through the liquid outlet pipe and the water pump. When heat is dissipated, the cooling chamber is filled with the coolant. The heat generated when the transformer body is working is absorbed by the coolant. At this time, the water pump is turned on to extract the coolant in the cooling chamber. At this time, the coolant flows into the liquid distribution pipe and the cooling pipe on one side in sequence through the water pump, and then flows back to the cooling chamber through the liquid distribution pipe and the liquid inlet pipe on the other side. When the coolant passes through the cooling pipe, it is first cooled and then flows back to the cooling chamber, so as to avoid the overheated coolant flowing directly back to the cooling chamber without cooling. At the same time, the transformer body is cooled, thereby improving the performance of the transformer body.

[0017] 2. The utility model can make the use of the transformer more convenient through the pulley and the mounting ear plate. When the transformer needs to be moved, the operator pushes the transformer casing, and the mounting ear plate rotatably arranged at the lower end of the fixed seat adjusts its position according to the force direction until the mounting ear plate is adjusted to a suitable position. At this time, the transformer casing is continued to be pushed to make the pulley arranged inside the mounting ear plate roll on the ground, and the base is driven to move together with the transformer casing through the pulley until the transformer is moved to a suitable position before welding operation is performed, thereby avoiding the need for the operator to move the transformer when it needs to be moved, thereby simplifying the moving process of the transformer.

[0018] 3. The utility model can accelerate the cooling of the coolant in the cooling pipe through the fan blades and the motor. When the coolant after absorbing heat is pumped out by the water pump, it flows into the cooling pipe from the liquid distribution pipe. At this time, the coolant with higher temperature transfers the heat to the pipe wall of the cooling pipe. Then the motor is turned on to make the output shaft of the motor drive the fan blades to rotate. When the fan blades rotate, the air below the fan blades flows upward and forms an airflow. At this time, the airflow with lower temperature contacts the cooling pipe with higher temperature. When the airflow blows the cooling pipe, the airflow takes away the heat on the cooling pipe, avoiding the coolant from being cooled in time and being transported to the cooling chamber, thereby preventing the cooling effect of the coolant from decreasing.

[0028] During use, when heat is dissipated, the cooling chamber 15 is filled with coolant, and the heat generated when the transformer body 16 is working is absorbed by the coolant. At this time, the water pump 6 is turned on to allow the water pump 6 to extract the coolant in the cooling chamber 15. At this time, the coolant flows into the liquid distributor 7 and the cooling pipe 9 on one side through the water pump 6 in sequence, and then flows back to the cooling chamber 15 through the liquid distributor 7 and the liquid inlet pipe 5 on the other side. When the coolant passes through the cooling pipe 9, it is first cooled and then flows back to the cooling chamber 15.

[0030] See also Figure 1 and Figure 2 A motor 11 is fixedly installed inside the base 1, and the output shaft of the motor 11 extends into the heat dissipation cavity 8. The motor 11 is located inside the heat dissipation cavity 8, and fan blades 10 are fixedly installed outside the output shaft, and the fan blades 10 are located below the cooling pipe 9, so that the fan blades 10 can be driven to rotate through the base 1.

After the coolant has absorbed the heat, it is extracted through the water pump 6 and flows from the liquid distribution pipe 7 into the cooling pipe 9. At this time, the coolant with a higher temperature transfers the heat to the pipe wall of the cooling pipe 9, and then the motor 11 is turned on, so that the output shaft of the motor 11 drives the fan blades 10 to rotate. When the fan blades 10 rotate, the air below the fan blades 10 flows upward and forms an airflow. At this time, the airflow with a lower temperature contacts the cooling pipe 9 with a higher temperature. When the airflow blows the cooling pipe 9, the airflow takes away the heat on the cooling pipe 9.
