Description

Technical Field

[0001] This utility model relates to the field of stainless steel production and processing, and in particular to a welding insulation device for stainless steel forgings. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Some stainless steel forgings require welding after forging. To prevent deformation and cracking at the weld, maintain a stable temperature at the weld, and improve welding quality and efficiency, the welded product is usually kept at a certain temperature for a period of time.

[0003] In existing technologies, the common insulation method involves placing the product directly into an insulated box for a period of time. The insulated box itself uses heating wires to maintain the temperature of the welded product for a specific period. However, welding is done one product at a time, making it impossible to weld multiple products simultaneously and place them in the insulated box. Therefore, to address this issue, an inlet and outlet are typically provided on the insulated box, and a conveyor belt is placed inside. Products are fed into the insulated box through the inlet, insulated for a period, and then discharged through the outlet. This structure presents several problems: the heating wires are usually located close to the inner wall of the insulated box, while the inlet and outlet are exposed to outside air, leading to uneven temperature distribution within the box, affecting the insulation effect and thus the welding quality. Furthermore, it consumes relatively high energy. Therefore, improving the insulation effect and ensuring welding quality is a direction that those skilled in the art need to address. Summary of the Invention

[0004] The purpose of this utility model is to provide a welding insulation device for stainless steel forgings. By using this structure, the insulation effect is effectively improved, the welding quality of the product is guaranteed, and energy consumption and cost are saved.

[0008] The fan is installed on the heating box, and the air outlet of the fan is connected to the heating chamber. The outer wall of the heating box is provided with a plurality of heat outlets corresponding to the heating port, and the heat outlets are connected to the heating chamber.

[0009] It is also provided with a pipeline that matches the heating port, and each of the pipelines is connected to a heating port and a heat outlet at both ends.

[0010] In the above technical solution, multiple air guide plates are provided on the inner wall of the heating chamber at the air outlet of the fan, and air guide channels are formed between adjacent air guide plates.

One end of the U-shaped heating tube passes through the heating box and is connected to the power supply. The U-shaped heating tube is located directly below the air outlet of the fan.

[0012] In the above technical solution, the U-shaped heating tube is fitted with multiple fins, and the multiple fins are arranged at intervals on the U-shaped heating tube.

Relief cavity. Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: See Figure 1-4 As shown, a welding insulation device for stainless steel forgings includes an insulation box 1 and a heating mechanism. The insulation box 1 is provided with an insulation cavity 2. The outer wall of the insulation box 1 is provided with an inlet 3 and an outlet 4 that communicate with the insulation cavity 2.

[0028] The outer wall of the heat preservation box 1 is also provided with a plurality of heating ports 5 that communicate with the heat preservation cavity 2;

[0029] The heating mechanism includes a heating box 6, a fan 7, and a heating component 8. The heating box 6 is provided with a heating chamber 9, and the heating component 8 is disposed in the heating chamber 9.

[0030] The fan 7 is installed on the heating box 6, and the air outlet of the fan 7 is connected to the heating chamber 9. The outer wall of the heating box 6 is provided with a plurality of heat outlets 10 corresponding one-to-one with the heating port 5, and the heat outlets 10 are connected to the heating chamber 9.

[0031] It is also provided with a pipe 11 that matches the heating port 5, and each of the two ends of the pipe 11 is connected to a heating port 5 and a heat outlet 10 respectively.

[0032] In this embodiment, a conveyor line is installed in actual use. The middle of the conveyor line is located inside the insulation chamber, with one end passing through the inlet and the other end passing through the outlet, also outside the insulation chamber. The welded product is placed on the conveyor line, enters the insulation chamber through the inlet, is kept warm, and then exits through the outlet. This method achieves predetermined insulation time for the product based on the conveyor speed and the insulation temperature of the chamber, ensuring the welding quality. However, since the inlet and outlet are connected to the outside of the insulation chamber, cold air from outside may enter the insulation chamber through the inlet and outlet, thus affecting the insulation effect. Therefore, in this embodiment, a separate heating mechanism is also provided. A heating chamber is set inside the heating box, and a heating component is installed inside the heating chamber. A fan is installed on top of the heating box, and the air outlet of the fan is connected to the heating chamber. In use, the fan sends outside air into the heating chamber through the air outlet, and the heating component heats the air in the heating chamber. Since the air outlet is connected to the heating port of the insulation box through a pipeline, the air blown into the heating chamber by the fan can only be sent out from the air outlet and then sent into the insulation chamber through the pipeline and the heating port. This ensures that the hot air in the insulation chamber has a set temperature to keep the product warm. At the same time, since the heating box continuously supplies hot air to the insulation chamber, the hot air in the insulation chamber can only be sent out from the inlet and outlet. This prevents outside cold air from entering the insulation chamber from the inlet and outlet, ensuring that the temperature inside the insulation chamber remains relatively stable, thereby ensuring the insulation effect on the product.

[0033] See Figure 2 , 3 As shown, multiple air guide plates 12 are provided on the inner wall of the heating chamber 9 at the air outlet of the fan 7. Adjacent air guide plates 12 form an air guide channel 13. The multiple air guide channels 13 are arranged sequentially along the extension direction of the heating component 8, and the air guide channels 13 are located directly above the heating component 8.

[0034] In this design, the air outlet of the fan is shorter than the length of the heating element. To ensure that the cold air blown out by the fan (or the air whose temperature has not yet reached the temperature required by the insulation cavity) is heated as soon as possible, and to prevent cold air from being directly sent out of the heat outlet, while also slowing down the flow rate of the cold air in contact with the heating element and improving the heating effect of the heating element on the cold air, a guide plate is set up to form multiple air guide channels. The lower width of the air guide channel is greater than the upper width of the air guide channel, so that the wind speed of the air blown out of the fan outlet will gradually slow down. Furthermore, the air guide plate provides some obstruction and slows down the wind speed, allowing the cold air to contact the heating element at a slower speed. After being heated by the heating element, it is then sent out of the heat outlet.

[0035] See Figure 2 ,3 As shown, the heating component 8 includes a U-shaped heating tube 14, which is installed in the middle of the heating chamber 9. One end of the U-shaped heating tube 14 passes through the heating box 6 and is connected to the power supply. The U-shaped heating tube 14 is located directly below the air outlet of the fan 7.

[0036] In this embodiment, the U-shaped opening of the U-shaped heating tube faces right, and the left end of the U-shaped heating tube is located near the left inner wall of the heating chamber. The front and rear ends of the right side of the U-shaped heating tube pass through the heating box and are located outside the heating box, connected to the power supply. The power supply provides power to the U-shaped heating tube, causing it to be heated. The heat outlets are spaced from left to right on the rear wall of the heating box, with the bottom plane of the heat outlet below the bottom plane of the U-shaped heating tube. The top plane of the heat outlet is also as close as possible to, or below, the bottom plane of, the bottom of the air guide channel is close to the U-shaped heating tube. This ensures that the delivered hot air contacts the U-shaped heating tube as quickly as possible, preventing cold air from leaking through the U-shaped heating tube and exiting through the heat outlet, thus guaranteeing the heating effect on the cold air.

[0037] See Figure 2 , 3 As shown, the U-shaped heating tube 14 is fitted with a plurality of fins 15, and the plurality of fins 15 are arranged at intervals on the U-shaped heating tube 14.

[0038] To improve the heating effect of the air delivered by the fan and the heating area of ​​the U-shaped heating tube, thereby enhancing the heating efficiency of cold air and increasing energy utilization, multiple fins are spaced apart on the U-shaped heating tube. When the U-shaped heating tube generates heat, the heat is transferred to the fins, which also act as heat conductors, increasing the contact area with the air, improving heating efficiency and effect, and saving energy and reducing costs.

[0039] See Figure 2 , 3 As shown, a support block 16 is also provided at the bottom of the heating chamber 9, and the bottoms of the plurality of fins 15 abut against the support block 16. The right end of the U-shaped heating tube is connected to the heating box, and the support block is set near the left side of the U-shaped heating tube. In this way, the left end of the U-shaped heating tube can be supported by the support block, while the right end is positioned by the heating box, so that the U-shaped heating tube is suspended and will not deform.

[0040] The outer cover of the insulation box 1 is provided with a first insulation sleeve 17. The first insulation sleeve will make way for the inlet and outlet of the material to avoid affecting the entry and exit of the product. The first and second insulation sleeves will cover the connection between the pipeline and the heating port to minimize the heat loss of the insulation box, ensure the insulation effect, save energy and reduce costs.

[0041] The heating box 6 is equipped with a second insulation sleeve 18 on its outer cover; the second insulation sleeve also covers the connection between the pipeline and the heat outlet, further improving the insulation effect, saving energy and reducing costs.

[0042] See Figure 4 As shown, the top of the second insulation sleeve 18 is provided with a relief cavity 19, and the bottom of the fan passes through the relief cavity and is installed on the top surface of the heating box. The relief cavity facilitates the installation of the fan.
