Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding spatter shielding device. Background Art

[0002] Tungsten inert gas (TIG) welding is a welding technique that uses argon as a shielding gas, also known as argon gas shielded welding. In TIG welding, argon shielding gas is passed around the arc to isolate the air from the welding area and prevent oxidation of the welding area. It utilizes the protection of argon for the metal welding material, and through a high current, the welding material is melted into a liquid state on the base material to be welded to form a molten pool, enabling metallurgical bonding between the base metal and the welding material. Since argon does not chemically react with metals at high temperatures and does not dissolve in the molten metal, it can protect the weld from oxidation and contamination, thus obtaining high-quality welds.

[0003] Stainless steel washers are generally fixed on stainless steel parts by TIG welding. During the TIG welding process of stainless steel washers, spatter slag is generated, resulting in local slag on the product that cannot be completely removed. Moreover, the stainless steel washers are not clamped, there are gaps after welding, and the temperature at the welding point is relatively high, making it easy for workers to get scalded when taking the parts. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a welding spatter shielding device, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The welding spatter shielding device includes a tooling base. A clamp is provided on the tooling base, and a stainless steel part is clamped by the clamp. A stainless steel washer is arranged on the upper surface of the stainless steel part. A shielding cover is fixedly installed on the upper surface of the tooling base. A pressing mechanism is fixedly installed at the edge of the tooling base. The pressing mechanism includes a positioning base fixed on the tooling base, a positioning frame fixedly installed on the positioning base, a limiting pressure arm movably installed on the positioning frame, a pressing buckle movably installed above the limiting pressure arm. Heat dissipation air holes are opened on the tooling base, and a cooling mechanism is arranged in the heat dissipation air holes in the tooling base. The cooling mechanism includes a holding frame fixed in the heat dissipation air holes, a return spring arranged on the holding frame, a cooling iron block fixedly installed at the upper end of the return spring, and a thermoelectric cooler fixedly installed at the bottom of the cooling iron block. The thermoelectric cooler can reduce the temperature of the cooling iron block.

[0007] Furthermore, the pressing mechanism further includes a connecting pillar fixed at the end of the limiting pressure arm, a limiting pressure block fixedly installed at the lower end of the connecting pillar, and a handle fixedly installed at the upper end of the pressing buckle.

[0008] Furthermore, the limiting pressure block is installed at the output end of the limiting pressure arm through a connecting pillar. Both the buckle and the limiting pressure arm are provided with movable shafts, and both the buckle and the limiting pressure arm are movably installed on the positioning frame through the movable shafts. The limiting pressure arm will press down the stainless steel gasket.

[0009] Furthermore, bolts are provided at the four corners of the positioning base, and the positioning base is fixed on the tooling base through the bolts.

[0010] Furthermore, the cooling mechanism further includes heat dissipation fins fixed at the bottom of the semiconductor refrigeration chip. Positioning through holes are opened at the edges of both ends of the cage. An electromagnet is fixedly installed on one side of the reset spring on the cage, and the electromagnet will attract the cooling iron block to move downward.

[0011] Furthermore, screws are provided in the positioning through holes, and the cage is fixed in the heat dissipation air holes through the screws. The heat dissipation fins can dissipate heat through the heat dissipation air holes.

[0012] Furthermore, one end of the reset spring is fixed on the cage, the other end of the reset spring is fixed on the cooling iron block, the cold end of the semiconductor refrigeration chip is closely attached to the cooling iron block, the hot end of the semiconductor refrigeration chip is closely attached to the heat dissipation fins, and the cooling iron block is aligned with the solder joint on the stainless steel part up and down.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] During the use process, put down the limiting pressure arm. After putting down the limiting pressure arm, the limiting pressure block will fall on the stainless steel washer. After the limiting pressure block falls on the stainless steel washer, the buckle can be fastened. After fastening the buckle, the limiting pressure block at the end of the limiting pressure arm will press the stainless steel washer tightly on the stainless steel part, reducing the generation of gaps after welding. At the same time, the shielding cover can be blocked on one side of the stainless steel part to prevent the splashed welding slag from jumping onto the product during the welding process.

[0015] During the welding process, the semiconductor refrigeration chip can be started. After starting the semiconductor refrigeration chip, it will rapidly reduce the temperature of the cooling iron block. When the stainless steel washer is welded, turn off the electromagnet. After turning off the electromagnet, it will release the cooling iron block. The released cooling iron block will move upward under the action of the reset spring, making the cooling iron block closely attached to the lower part of the solder joint on the stainless steel part, rapidly reducing the temperature of the solder joint and reducing the occurrence of scalding accidents.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0022] As Figure 1 Figure 2 As shown, the welding spatter shielding device includes a tooling base 1, a clamp 8 is provided on the tooling base 1, a stainless steel part 5 is clamped by the clamp 8, a stainless steel washer 3 is provided on the upper surface of the stainless steel part 5, a shielding cover 4 is fixedly installed on the upper surface of the tooling base 1, a pressing mechanism 6 is fixedly installed at the edge of the tooling base 1, the pressing mechanism 6 includes a positioning base 601 fixed on the tooling base 1, a positioning frame 602 is fixedly installed on the positioning base 601, a limiting pressure arm 605 is movably installed on the positioning frame 602, a buckle 603 is movably installed above the limiting pressure arm 605, heat dissipation air holes 2 are formed in the tooling base 1, a temperature reduction mechanism 7 is provided in the heat dissipation air holes 2 in the tooling base 1, the pressing mechanism 6 can press the stainless steel washer 3 against the stainless steel part 5 to reduce the generation of gaps after welding, and the shielding cover 4 can prevent welding spatter from jumping onto the product, and the temperature reduction mechanism 7 can quickly reduce the temperature at the welding point to reduce the occurrence of scalding accidents.

[0023] As Figure 3 As shown, a shielding cover 4 is fixedly installed on the upper surface of the tooling base 1, the pressing mechanism 6 includes a positioning base 601 fixed on the tooling base 1, a positioning frame 602 is fixedly installed on the positioning base 601, a limiting pressure arm 605 is movably installed on the positioning frame 602, a buckle 603 is movably installed above the limiting pressure arm 605, the pressing mechanism 6 further includes a connecting pillar 606 fixed at the end of the limiting pressure arm 605, a limiting pressure block 607 is fixedly installed at the lower end of the connecting pillar 606, and a grip 604 is fixedly installed at the upper end of the buckle 603.

[0024] Specifically, during use, lower the limit pressure arm 605. After lowering the limit pressure arm 605, the limit pressure block 607 will fall on the stainless steel washer 3. After the limit pressure block 607 falls on the stainless steel washer 3, the buckle 603 can be buckled. After buckling the buckle 603, the limit pressure block 607 at the end of the limit pressure arm 605 will press the stainless steel washer 3 tightly against the stainless steel part 5, reducing the generation of gaps after welding. At the same time, the shielding cover 4 can be blocked on one side of the stainless steel part 5 to prevent the splashed welding slag from jumping onto the product during the welding process.

[0025] As Figure 4 shown, heat dissipation air holes 2 are provided on the tooling base 1. The temperature reduction mechanism 7 includes a cage 705 fixed in the heat dissipation air hole 2. A return spring 703 is provided on the cage 705. The upper end of the return spring 703 is fixedly installed with a temperature reduction iron block 701. A semiconductor refrigeration sheet 702 is fixedly installed at the bottom of the temperature reduction iron block 701. The temperature reduction mechanism 7 further includes heat dissipation fins 707 fixed at the bottom of the semiconductor refrigeration sheet 702. Positioning through holes 704 are provided at both ends of the cage 705. An electromagnet 706 is fixedly installed on the cage 705 on one side of the return spring 703.

[0026] Specifically, the semiconductor refrigeration sheet 702 can be started during the welding process. After starting the semiconductor refrigeration sheet 702, it will rapidly reduce the temperature of the temperature reduction iron block 701. After the stainless steel washer 3 is welded, turn off the electromagnet 706. After turning off the electromagnet 706, it will release the temperature reduction iron block 701. The released temperature reduction iron block 701 will move upward under the action of the return spring 703, making the temperature reduction iron block 701 closely attached to the lower part of the welding point on the stainless steel part 5, rapidly reducing the temperature of the welding point and reducing the occurrence of scalding accidents.

[0027] It should be noted that the present utility model is a welding spatter shielding device. During actual use, first, the stainless steel part 5 is clamped by the clamp 8. Then, the limit pressure arm 605 can be lowered. Since the limit pressure block 607 is installed at the output end of the limit pressure arm 605 through the connecting pillar 606, and both the buckle 603 and the limit pressure arm 605 are provided with movable shafts, the buckle 603 and the limit pressure arm 605 are movably installed on the positioning frame 602 through the movable shafts. Therefore, after the limit pressure arm 605 is lowered, the buckle 603 can be buckled to tightly press the stainless steel washer 3 on the stainless steel part 5, reducing the generation of gaps after welding. During the welding process, the shielding cover 4 will block on one side of the stainless steel part 5 to prevent welding slag from splashing onto the product. During the welding process, the semiconductor refrigeration sheet 702 can be started. After the semiconductor refrigeration sheet 702 is started, it will rapidly reduce the temperature of the cooling iron block 701. After the stainless steel washer 3 is welded, the electromagnet 706 is turned off. Since one end of the return spring 703 is fixed on the cage 705 and the other end of the return spring 703 is fixed on the cooling iron block 701, after the electromagnet 706 is turned off, it will release the cooling iron block 701. The released cooling iron block 701 will move upward under the action of the return spring 703, making the cooling iron block 701 closely adhere to the lower part of the welding point on the stainless steel part 5, rapidly reducing the temperature of the welding point and reducing the occurrence of scalding accidents. After the welding point cooling is completed, the electromagnet 706 can be restarted. After the electromagnet 706 is restarted, it will adsorb the cooling iron block 701 to reset the cooling iron block 701.
