Description

Technical Field

[0001] This utility model relates to the field of welding electrode processing technology, and in particular to a welding electrode baking device. Background Technology

[0002] Electrode baking is a pretreatment process for welding electrodes before use. It involves heating the electrodes to remove moisture and grease from the electrode coating and to promote a stabilization reaction of the coating components.

[0003] During the process, the heating temperature and time need to be controlled according to the type of welding rod. Generally, the welding rod is placed in a baking device, gradually heated to the specified temperature and then kept at that temperature before being slowly cooled. This process can enhance the dryness of the coating, avoid the formation of pores and cracks due to moisture evaporation during welding, and at the same time improve the bonding strength and stability of the coating, ensuring the smooth progress of the welding process and guaranteeing the mechanical properties and density of the weld.

[0004] A search revealed Chinese patent publication number CN206478957U, which describes a baking device for welding electrode production. The device includes a housing, with hot air flowing from left to right through three baking chambers. The side-entry baking method allows the side-intake of hot air to more easily remove moisture and other substances from the electrode coating. The hot air containing evaporated moisture from the electrode coating enters the hot air duct within the partition through a reversing fan, ensuring that both the upper and lower surfaces of the welding electrode are baked evenly. This results in a uniform baking area and avoids the problems of traditional welding electrode baking machines where the top is cold and the bottom is hot, or the area near the heating rod is hot while the area further away is cold. The demister absorbs moisture from the hot air and recirculates it into the blower, forming a hot air circulation that effectively saves energy. This utility model has a simple structure, saves energy, and provides uniform baking area and high baking efficiency for the welding rods. However, when placing the welding rods in bundles, the individual welding rods inside the bundles cannot fully contact the hot air. The side air intake and the baking effect on the upper and lower surfaces can only cover the outer layer of the welding rod bundle. The inner welding rods are blocked by the outer layer, resulting in insufficient heat exchange and the inability to effectively remove moisture and other substances. This leads to differences in the baking degree of the welding rods within the same bundle, making it impossible to achieve uniform baking of individual welding rods and affecting the consistency of the overall baking quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a welding rod baking device, which aims to improve the problem in the prior art where insufficient heat exchange and ineffective removal of moisture result in differences in the degree of baking of welding rods within the same bundle, making it impossible to achieve uniform baking of individual welding rods and affecting the consistency of overall baking quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a welding electrode baking device, comprising a shell, a baking chamber provided on the left side of the shell, a baking mechanism provided inside the baking chamber, the baking mechanism being used to bake the welding electrode evenly, a cooling chamber provided on the right side of the shell, a cooling mechanism being provided inside the cooling chamber, the cooling mechanism being used to slowly cool the welding electrode after baking, to avoid sudden cooling causing the coating to become brittle; The baking mechanism includes multiple mounting columns, which are fixedly connected to the four corners inside the baking mechanism. Multiple welding rod holders are fixedly connected at equal intervals inside the multiple mounting columns. Heat dissipation plates are fixedly connected to the bottom of each of the multiple welding rod holders. An electric heating rod is fixedly connected to the top of the inner side of the baking chamber. A circulation component is provided on the rear side of the outer shell.

[0007] The above technical solution provides a stable space for the welding rods by installing columns to support the multi-layer welding rod rack; heat dissipation plates assist in heat transfer, electric heating rods provide the heat source, and circulation components promote airflow, ensuring uniform heating of the welding rods. This solves the problem of large local temperature differences in traditional baking, ensures consistent baking quality between the welding rod coating and the core, and meets the requirements for welding rod pretreatment.

[0008] As a further description of the above technical solution: The cooling mechanism includes an insulated water tank, which is fixedly connected to the top right end of the outer shell. Circulating water pumps are fixedly connected to both the left and right sides of the top of the insulated water tank. Mounting brackets are fixedly connected to the bottom of each of the multiple heat dissipation plates. Circulating pipe I is fixedly connected inside each of the multiple mounting brackets. The input and output ends of the multiple circulating pipe I are respectively connected to the output end of the left circulating water pump and the left side of the insulated water tank. Two mesh plates are fixedly connected inside the cooling chamber. Circulating pipe II is fixedly connected to the bottom of each of the two mesh plates. The input and output ends of the two circulating pipe II are respectively connected to the output end of the right circulating water pump and the right side of the insulated water tank.

[0009] The above technical solution maintains the coolant temperature through an insulated water tank, and a circulating water pump drives the coolant to circulate in circulation pipe 1 and circulation pipe 2. Circulation pipe 1 absorbs the residual heat from the baking chamber, while circulation pipe 2 slowly cools the welding rods on the mesh plate, avoiding sudden cooling that could cause the coating to become brittle, ensuring stable welding rod performance, and improving subsequent welding results.

[0010] As a further description of the above technical solution: The circulation component includes a circulation box, which is fixedly connected to the rear side of the outer shell. The output end and input end of the circulation box are respectively connected to the top and bottom of the inner side of the baking chamber. Two fans are fixedly connected to the rear side of the inner side of the circulation box.

[0011] The above technical solution involves connecting the top and bottom of the baking chamber with the circulation box of the circulation component. The fan drives the air to form a circulation, which allows the hot air to spread evenly in the chamber and eliminates temperature dead zones. This ensures that the welding rods in different positions receive the same heating conditions, reduces local overheating or underheating, improves baking uniformity, and ensures the stable quality of each welding rod.

[0012] As a further description of the above technical solution: The baking mechanism also features a U-shaped groove, which is located on top of multiple welding rod holders.

[0013] Through the above technical solution: the U-shaped groove at the top of the welding rod holder can fix the welding rod and prevent it from rolling or shifting during the baking process; ensure that the welding rod is always in the preset heating position, avoid uneven heating caused by position changes, so that each welding rod can be baked evenly, ensure consistent baking effect, and reduce quality deviation.

[0014] As a further description of the above technical solution: The baking mechanism also includes heat dissipation holes, which are located on the top of multiple heat dissipation plates.

[0015] The above technical solution increases the contact area between hot air and welding rod through the heat dissipation holes on the top of the heat sink, allowing heat to be evenly diffused to the surface of the welding rod through the holes; it accelerates the heat exchange rate, shortens the baking time, ensures uniform heat transfer, further improves baking efficiency and uniformity, and optimizes the pretreatment effect of the welding rod.

[0016] As a further description of the above technical solution: Two hinges are fixedly connected to the left side and the middle of the front side of the outer shell, and a sealing door is fixedly connected to the right end of the two hinges on the left side and the two hinges on the right side.

[0017] Through the above technical solution: the hinges on the outer shell allow the sealed door to open and close flexibly, making it convenient to take out and put in the welding rod; after the sealed door is closed, it can reduce the loss of heat or cold in the chamber, maintain the stable environment required for baking and cooling, ensure stable temperature parameters, provide suitable conditions for welding rod processing, and ensure the processing effect.

[0018] As a further description of the above technical solution: Two pins are fixedly connected to the front right end of each of the two sealing doors, and fixing pins are fixedly connected to the front upper and lower ends and the right upper and lower ends of the outer shell.

[0019] The above technical solution allows the latch of the sealing door to cooperate with the fixing pin of the outer shell, which can firmly lock the sealing door and enhance the sealing performance of the chamber; reduce temperature fluctuations, ensure the stability of the baking and cooling processes, avoid energy loss and reduced processing effect due to poor sealing, and improve equipment reliability.

[0020] As a further description of the above technical solution: A temperature display is fixedly connected to the upper middle part of the front side of the sealing door on the left, and the temperature display is electrically connected to the electric heating rod.

[0021] Through the above technical solution: the temperature display on the left-side sealed door is electrically connected to the electric heating rod, which can provide real-time feedback on the temperature inside the baking chamber; this facilitates monitoring and adjustment by operators, ensuring that the baking temperature is accurately controlled within a suitable range, avoiding the impact of improper temperature on the quality of the welding rod, and improving the controllability of the baking process.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by placing the welding rod in the U-shaped groove of the welding rod placement rack, the electric heating rod heats the air, and the fan circulates the air through the circulation box. The hot air diffuses through the heat dissipation holes of the heat sink plate and fully contacts the welding rod to achieve uniform baking. This achieves stable placement and uniform heating of the welding rod during baking, reduces temperature differences, improves baking efficiency, ensures the quality of welding rod baking, and meets the pretreatment requirements before use of the welding rod.

[0023] 2. In this utility model, the coolant from the insulated water tank is delivered to the first circulation pipe by the left circulating water pump, and then flows back after absorbing the residual heat from the heat dissipation plate; the coolant is delivered to the second circulation pipe by the right circulating water pump, and then flows back after cooling the welding rod on the mesh plate. The two circuits are independently temperature controlled, which realizes the slow cooling after the welding rod is baked, avoids the embrittlement of the coating due to sudden cooling, and at the same time handles the residual heat in the baking chamber, ensures cooling stability, improves the quality of the welding rod, and meets the requirements for subsequent use.

The electric heating rod 34 is powered on to generate heat, which heats the air in the baking chamber 2. The fan 352 in the circulation box 351 is started, which draws the cold air at the bottom of the baking chamber 2 into the circulation box 351 and delivers it to the top of the baking chamber 2 through the circulation box 351 to form an air circulation. During the circulation process, the hot air is evenly diffused through the heat dissipation holes 37 at the top of the heat dissipation plate 33 and comes into full contact with the welding rod to achieve uniform baking of the welding rod. During the baking process, the design of the U-shaped groove 36 ensures that the welding rod is stably placed on the welding rod holder 32, preventing it from rolling; the setting of the heat dissipation plate 33 and heat dissipation holes 37 increases the contact area between hot air and welding rod, improving baking efficiency; the circulation component 35 ensures that the temperature distribution in the baking chamber 2 is uniform, reducing temperature differences; The mounting column 31 provides support for the electrode holder 32, the electric heating rod 34 serves as a heat source, the circulation component 35 promotes airflow, and the U-shaped groove 36 and heat dissipation holes 37 optimize the baking conditions; thus, the electrode is baked evenly in the electrode baking scenario, ensuring the quality of the electrode.

[0033] Reference Figure 2 , Figure 4 and Figure 6 The cooling mechanism 5 includes an insulated water tank 51, which is fixedly connected to the top right end of the outer shell 1. Circulating water pumps 52 are fixedly connected to the top left and right sides of the insulated water tank 51. Mounting brackets 53 are fixedly connected to the bottom of multiple heat dissipation plates 33. Circulating pipes 54 are fixedly connected inside the multiple mounting brackets 53. The input and output ends of the multiple circulating pipes 54 are respectively connected to the output end of the left circulating water pump 52 and the left side of the insulated water tank 51. Two mesh plates 55 are fixedly connected inside the cooling chamber 4. Circulating pipes 56 are fixedly connected to the bottom of the two mesh plates 55. The input and output ends of the two circulating pipes 56 are respectively connected to the output end of the right circulating water pump 52 and the right side of the insulated water tank 51. Specifically, the insulated water tank 51 of the cooling mechanism 5 is fixedly connected to the top right end of the outer shell 1, and circulating water pumps 52 are fixedly connected to both the left and right sides of the top; mounting brackets 53 are fixedly connected to the bottom of multiple heat dissipation plates 33, and circulating pipes 54 are fixedly connected inside the multiple mounting brackets 53. The input and output ends of the multiple circulating pipes 54 are respectively connected to the output end of the left circulating water pump 52 and the left side of the insulated water tank 51; two mesh plates 55 are fixedly connected inside the cooling chamber 4, and circulating pipes 56 are fixedly connected to the bottom of the two mesh plates 55. The input and output ends of the two circulating pipes 56 are respectively connected to the output end of the right circulating water pump 52 and the right side of the insulated water tank 51. When the welding rods need to be cooled after baking, the left circulating water pump 52 starts, delivering the coolant in the insulation water tank 51 to the first circulation pipe 54. The coolant flows in the first circulation pipe 54, absorbing the residual heat on the welding rod placement rack 32 through the heat dissipation plate 33, and then flows back to the insulation water tank 51. The right circulating water pump 52 starts simultaneously, delivering the coolant in the insulation water tank 51 to the second circulation pipe 56. The coolant flows in the second circulation pipe 56, cooling the baked welding rods placed on the mesh plate 55, and then flows back to the insulation water tank 51. The insulated water tank 51 maintains the coolant within a suitable temperature range to prevent the welding rod from cooling down too quickly due to excessively low coolant temperature; the first circulation pipe 54 and the second circulation pipe 56 form an independent circulation loop to regulate the temperature of the baking chamber 2 and the cooling chamber 4 respectively; the mesh plate 55 enables the welding rod and coolant to exchange heat through thermal radiation and thermal conduction, achieving slow cooling. Mounting bracket 53 provides fixed support for circulation pipe 54, ensuring it is in close contact with heat sink 33; circulating water pump 52 provides power to drive the coolant to circulate within the system; insulated water tank 51 ensures the stability of coolant temperature; The first circulation pipe 54 pre-cools the residual heat in the baking chamber 2, and the second circulation pipe 56 performs the main cooling of the welding rod in the cooling chamber 4. This achieves the effect of slowly cooling the welding rod after baking in the welding rod baking scenario, avoiding the embrittlement of the coating caused by sudden cooling, and ensuring the quality of the welding rod.

[0034] Reference Figure 1 and Figure 2 Two hinges 6 are fixedly connected to the left side and the middle of the front side of the outer casing 1. Sealing doors 7 are fixedly connected to the right ends of the two hinges 6 on the left side and the two hinges 6 on the right side. Two pins 8 are fixedly connected to the right front ends of the two sealing doors 7. Fixing pins 9 are fixedly connected to the upper and lower front ends and the upper and lower right ends of the outer casing 1. A temperature display 10 is fixedly connected to the upper middle part of the front side of the left sealing door 7. The temperature display 10 is electrically connected to the electric heating rod 34. Specifically, the sealing door 7 can rotate around the hinge 6 to open and close the baking chamber 2 and the cooling chamber 4; when the sealing door 7 is closed, the latch 8 can be inserted into the corresponding fixing pin 9 to lock the sealing door 7, ensuring the airtightness of the baking chamber 2 and the cooling chamber 4 and reducing the loss of heat or cold. Because the temperature display 10 is electrically connected to the electric heating rod 34, it can display the temperature inside the baking chamber 2 in real time when the electric heating rod 34 is working; the operator can understand the temperature status inside the baking chamber 2 by observing the value of the temperature display 10. The rotational characteristics of hinge 6 ensure smooth opening and closing of the sealed door 7; the mating structure of the latch 8 and the fixing pin 9 ensures the stability of the sealed door 7 after it is closed; the temperature display 10 provides intuitive information for temperature monitoring.

[0035] Working principle: Before the device is put into operation, the operator opens the sealing door 7 around the hinge 6 and places the welding rod to be baked in the U-shaped groove 36 at the top of the welding rod placement rack 32 in the baking mechanism 3. The U-shaped groove 36 can prevent the welding rod from rolling and ensure its stable placement. After placement, the sealing door 7 is closed and the pin 8 is inserted into the fixing pin 9 to seal the baking chamber 2 and reduce heat loss. When the baking mechanism 3 is activated, the electric heating rod 34 generates heat to heat the air inside the baking chamber 2. At the same time, the fan 352 of the circulation component 35 on the rear side of the outer shell 1 is activated, drawing the cold air from the bottom of the baking chamber 2 into the circulation box 351, and then transporting it to the top of the baking chamber 2 through the circulation box 351 to form an air circulation. During the circulation process, the hot air is evenly diffused through the heat dissipation holes 37 on the top of the heat dissipation plate 33, making full contact with the welding rod to achieve uniform baking. The temperature display 10 displays the temperature inside the baking chamber 2 in real time, making it easy for the operator to monitor the baking status. After baking is complete, open the sealed door 7 of the baking chamber 2, take the welding rod from the welding rod rack 32 and place it on the mesh plate 55 in the cooling chamber 4; close the sealed door 7 of the cooling chamber 4 and lock it with the latch 8 and the fixing pin 9 to ensure the stability of the cooling environment; When the cooling mechanism 5 is activated, the circulating water pumps 52 on the left and right sides of the top of the insulated water tank 51 start simultaneously. The left circulating water pump 52 delivers the coolant in the insulated water tank 51 to the first circulation pipe 54. The coolant flows in the first circulation pipe 54, absorbs the residual heat in the baking chamber 2 through the heat dissipation plate 33, and then flows back to the insulated water tank 51. The right circulating water pump 52 delivers the coolant in the insulated water tank 51 to the second circulation pipe 56. The coolant flows in the second circulation pipe 56, exchanges heat with the welding rod through the mesh plate 55, slowly cools the welding rod, and then flows back to the insulated water tank 51. The insulated water tank 51 maintains the coolant within a suitable temperature range to prevent the coating of the welding rod from becoming brittle due to sudden cooling. After cooling is complete, open the sealed door 7 of the cooling chamber 4 and take out the cooled welding rod; if baking is required again, repeat the above process.
