Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a welding temperature reduction device. Background Art

[0002] The engine thermal management module is an important part of the modern automobile engine system. Its main function is to control and manage the engine's operating temperature to ensure that the engine can operate within the most suitable temperature range and improve the vehicle's performance and fuel efficiency. The engine thermal management module is usually composed of the following parts: water tank and water pump, radiator and fan, temperature sensor, temperature control valve, electronic control module (ECU). Among them, the temperature control valve controls the opening and closing of the cooling system according to the data collected by the temperature sensor to adjust the circulation flow speed and direction of the coolant, thereby adjusting the engine's operating temperature. The electronic control module (ECU) is responsible for the overall control and monitoring of the engine thermal management module. According to the feedback information from the temperature sensor, it controls the working status of the water pump, fan and temperature control valve to ensure that the engine operates within the optimal temperature range. When manufacturing the temperature control valve, the actuator needs to be installed in a sealed housing and welded by laser hot melt. The two half shells are welded together in a certain way. Since the two half shells are made of polymer materials, the current products will have the phenomenon of weld charring and weld paste after welding. The main reason is that the heat per unit area is not transferred to the welding ribs in time, and the heat on the surface of the product increases suddenly, causing the surface of the product material to reach the melting point and ignition point, resulting in weld charring and weld paste. After the product is laser welded, due to the product material, the welding power is high, the time is long, and the temperature at the position of the welding rib is very high. The next workstation of the product is airtight testing. Since the temperature is too high, it will affect the airtight test results. The present application provides a welding cooling device, which can locally cool the welding point during the welding process to avoid long-term excessively high local temperature, and cool the entire device after welding to avoid affecting subsequent airtight testing.

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.

[0023] Example 1

[0024] like Figure 1-6 As shown, a welding cooling device is used for the laser sealing welding process of the temperature control valve actuator housing of the automotive engine thermal management module. The welded part refers to the actuator housing and the internal motor and transmission gear installed. The welding track is a continuous track located at the edge of the welded part. The welding cooling device includes a high heat removal cooling module and a waste heat removal cooling module.

[0025] The high-heat removal and cooling module is used to cool the welding point during the welding process. The high-heat removal and cooling module includes a blowing device 1 installed on the welding fixture 1. The blowing device 1 has an air outlet 13 that matches the welding track. Specifically, the blowing device 1 includes a mounting port processed on the welding fixture 1. The mounting port is located directly below the welding piece. The side wall of the mounting port corresponds to the welding track. An air supply channel 5 is processed on the side wall of the mounting port. In this embodiment, the welding fixture 1 itself has a positioning port that matches the welding piece. The positioning port also forms a mounting port. No additional opening is required, and the manufacturing is convenient. The mounting port is installed with a An air guide ring 2 is provided, and an air outlet 13 is formed between the air guide ring 2 and the side wall of the installation port. In this embodiment, a step 6 is processed at the installation port, and the air guide ring 2 is connected with a connecting plate 3, and the connecting plate 3 is sealed and connected to the step 6, so that air can be discharged in one direction. An air joint 4 connected to an air supply channel 5 is installed on the bottom plate, and then connected to an air source. The air guide ring 2 does not extend upward beyond the welding fixture 1, so that the airflow flows out from the middle position of the installation port without overflowing upward, thereby avoiding interference with welding and concentrating the airflow at the same time. The air outlet 13 is close to the welding position, so that the heat generated during welding can be quickly taken away, thereby avoiding the welding track being in a high temperature state for a long time.

[0026] The waste heat removal and cooling module is used to cool the weldment as a whole after welding. The waste heat removal and cooling module includes an air blowing device 2 installed on the conveying channel. The air blowing device 2 is processed with an air outlet 2 9 facing the weldment. Specifically, the air blowing device 2 includes a connecting seat, and the connecting seat is processed with an air supply channel 2 12. The air outlet 2 9 is connected to the air supply channel 2 12. For the convenience of manufacturing, the connecting seat includes a substrate 7, and the substrate 7 is processed with a mounting hole 8, which is then installed in the conveying channel, specifically installed on conveying components such as a manipulator and a conveyor belt. During the conveying process, air flow is continuously blown to the weldment for cooling. The air supply channel 2 12 is processed in the substrate 7, specifically processed by drilling. An air inlet hole 10 and a connecting hole 11 are processed on the substrate 7. The air joint is connected through the air inlet hole 10, and the connection between multiple substrates 7 is achieved through the connecting hole 11. When a single substrate 7 is used, the connecting hole 11 can be blocked.
