Description

Technical Field

[0001] This utility model relates to the field of cooling devices, and in particular to a cooling device for low alloy welding wire rods. Background Technology

[0002] Low-alloy welding wire rods refer to disc-shaped metal materials used to manufacture welding wires, containing a small amount of alloying elements (generally less than 5% in total content). These mainly include manganese (Mn), silicon (Si), chromium (Cr), nickel (Ni), and molybdenum (Mo). The addition of these alloying elements can improve the performance of the welding wire. For example, manganese can improve strength and toughness, silicon can increase strength and hardness, and chromium, nickel, and molybdenum can improve corrosion resistance and heat resistance. In the production process, cooling is a crucial step. Inappropriate cooling methods or parameters may lead to uneven internal structure of the wire rod, resulting in defects such as coarse grains and segregation, which in turn affect the performance of the welding wire, such as reduced strength, insufficient toughness, and poor welding performance.

[0003] There are two existing cooling methods: water cooling and air cooling. Low alloy welding wire rods have a high temperature after rolling and other processes. Water cooling can provide a highly efficient cooling effect, allowing the rods to cool down quickly. Compared with air cooling, it can greatly shorten the cooling time, improve production efficiency, and meet the requirements of large-scale industrial production.

[0004] Currently, water-cooling devices have the following problems: 1. Directly spraying cooling water onto the surface of the wire rod causes rapid cooling, which can easily generate significant thermal stress inside the wire rod. This thermal stress may lead to deformation or even cracking of the wire rod, seriously affecting product quality and consequently its welding and subsequent processing performance. 2. They are limited in function, only capable of cooling the wire rod and lacking additional functions, such as wire rod diameter detection. This requires the purchase of additional equipment, increasing manpower and material costs. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for low-alloy welding wire rods, in order to solve the problems mentioned in the background art, where direct spraying of cooling water onto the surface of the rod leads to rapid cooling and generates significant thermal stress inside the rod. This thermal stress can cause deformation or even cracking of the rod, seriously affecting product quality and consequently its welding performance and subsequent processing performance. Furthermore, the device is functionally limited, only capable of cooling the rod without additional functions such as rod diameter detection, requiring the purchase of additional instruments and increasing manpower and material costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low alloy welding wire rod cooling device, comprising a main body, a front baffle plate installed on the front surface of the main body, a rear baffle plate installed on the rear surface of the main body, a partition plate installed at the center of the interior of the main body, and through holes opened at the center of the front baffle plate, the rear baffle plate and the partition plate, wherein the front end and the rear end of the through holes are both designed with smooth arc surfaces.

[0007] A base is installed at the center of the partition plate, and a spring is installed on the base. Multiple springs are arranged symmetrically in a circle on the base. A first contact is installed on the base, a second contact is installed below the first contact, and a third contact is installed below the second contact. A pressing block is sleeved on the front end of the base, and a detection hole is opened on the pressing block. The diameter of the detection hole is slightly smaller than that of the through hole.

[0008] A support column is installed on the lower surface of the main body of the equipment, and a mixing box is installed below the main body of the equipment.

[0009] Preferably, an audible and visual alarm is installed on one side of the main body of the device. The first contact, the second contact, and the third contact are all electrically connected to the audible and visual alarm. The first contact is higher than the second contact, and the second contact is higher than the third contact.

[0010] Preferably, a water storage tank is installed on the upper surface of the main body of the equipment, a second pipe is installed on the front surface of the water storage tank, a cooling water pipe is installed at the rear of the water storage tank, a perforated filter plate is installed inside the water storage tank near the front, and an activated carbon filter plate is installed in front of the perforated filter plate.

[0011] Preferably, a front annular pipe is installed in front of the partition plate, a guide roller is installed in front of the front annular pipe, a rear annular pipe is installed behind the partition plate, a guide roller is installed behind the rear annular pipe, water troughs are provided on both sides of the front and rear annular pipes, and spray heads are installed on both the front and rear annular pipes. Multiple spray heads are provided and are symmetrically distributed in a circle.

[0012] Preferably, the second pipe is connected to the front annular pipe, and the cooling water pipe is connected to the rear annular pipe.

[0013] Preferably, the mixing box has a mixing chamber inside, a first slide is installed on the front surface of the mixing box, a second slide is installed on the rear surface of the mixing box, and a pull-out plate is installed on both the first and second slides, with filter holes provided on the pull-out plate.

[0014] Preferably, a No. 1 pipe is installed inside the mixing chamber, and a water pump is installed on the rear surface of the main body of the equipment. The output end of the water pump is connected to a water storage tank through a pipe.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. The water storage tank and mixing tank set in this utility model are used in the process of the wire rod carrying a large amount of heat energy after the wire rod has just undergone rolling and other processes. This heat energy is quickly absorbed by the cooling water, and the temperature of the cooling water will rise significantly in a very short time. The originally low temperature water is heated into a higher temperature hot water. The hot water enters the No. 1 slide through the lower water tank and flows into the mixing tank. Then the annular pipe is connected to the external cooling water pipe to ensure that the water sprayed out by the rear annular pipe is always cooling water. The cold water flows into the mixing tank through the lower water tank and forms warm water in the mixing tank. The warm water is pumped out by the water pump and sent into the front annular pipe. This realizes the recycling of water resources and the gradual cooling of the wire rod.

[0017] 2. The separator, pressing block, and detection hole provided in this utility model can trigger an alarm during use via an audible and visual alarm. When the pressing block is subjected to changes in force, triggering different contact points, the audible and visual alarm will sound, allowing operators to quickly learn of any abnormalities in the wire rod diameter and adjust the rolling process parameters in a timely manner to ensure the stability of product quality. At the same time, the different contact points can also issue different levels of alarms based on the degree of deviation in wire rod diameter, making it convenient for operators to quickly determine the severity of the problem and take appropriate measures.

[0025] This utility model provides a technical solution; please refer to the appendix. Figure 1 - Appendix Figure 5 As shown, the device includes a main body 1, a front baffle 6 installed on the front surface of the main body 1, and a rear baffle 10 installed on the rear surface of the main body 1. The main body 1, the front baffle 6, and the rear baffle 10 together form a relatively enclosed cooling space, which can not only effectively block external impurities from interfering with the cooling process, but also reduce heat loss to the surrounding environment to a certain extent, thereby improving cooling efficiency.

[0026] Specifically, a partition plate 21 is installed at the center of the main body 1 of the equipment. A through hole 7 is opened at the center of the front baffle 6, the rear baffle 10 and the partition plate 21. The front and rear ends of the through hole 7 are designed with smooth arc surfaces, which provides a precise travel channel for the wire rod, ensuring the stable operation of the wire rod in the device and ensuring the continuity of the cooling process.

[0027] Furthermore, a base 27 is installed at the center of the partition plate 21, and a spring 28 is installed on the base 27. Multiple springs 28 are arranged symmetrically in a circle on the base 27. A first contact 24 is installed on the base 27, a second contact 25 is installed below the first contact 24, and a third contact 26 is installed below the second contact 25.

[0028] Specifically, a pressing block 22 is fitted onto the front end of the base 27. The pressing block 22 has a detection hole 23, the diameter of which is slightly smaller than that of the through hole 7. When the wire rod passes through the detection hole 23, if the wire rod diameter is abnormal, the pressing block 22 will be subjected to varying degrees of compression. This design enables preliminary detection of the wire rod diameter, real-time monitoring of the wire rod diameter, and timely detection of possible rolling dimension deviations during the production process. This avoids the generation of more defective products due to wire rod diameter issues in subsequent processing, reduces material waste, and lowers production costs.

[0029] Considering the potential for abnormal wire rod diameter, an audible and visual alarm 9 is installed on one side of the main body 1. Contacts 24 (number 1), 25 (number 25), and 26 (number 3) are electrically connected to the alarm 9. Contact 24 is higher than contact 25, and contact 25 is higher than contact 26, forming a complete alarm system. When the pressure block 22 is subjected to a change in force, triggering different contacts, the alarm 9 sounds, allowing operators to quickly identify any abnormalities in the wire rod diameter and adjust rolling process parameters accordingly to ensure product quality stability. Furthermore, the different contact settings can issue different levels of alarms based on the degree of wire rod diameter deviation, facilitating rapid assessment of the problem's severity and enabling appropriate action. When the pressure block 22 touches contact 24, indicating a minor diameter error, contact 24 activates the optical module of the alarm 9, flashing an indicator light to alert the operator. When the pressure block 22... When contact point 25 is touched, it indicates that the diameter error is large. Contact point 24 activates the optical module of the audible and visual alarm 9, and contact point 25 activates the sound module of the audible and visual alarm 9, which alerts the staff by flashing lights and making sounds.

[0030] Furthermore, a support column 8 is installed on the lower surface of the main body 1, a mixing tank 3 is installed below the main body 1, and a water storage tank 2 is installed on the upper surface of the main body 1.

[0031] Specifically, a second pipe 18 is installed on the front surface of the water storage tank 2, and a cooling water pipe 12 is installed at the rear of the water storage tank 2. A perforated filter plate 19 is installed inside the water storage tank 2 near the front, and an activated carbon filter plate 20 is installed in front of the perforated filter plate 19. The perforated filter plate 19 and the activated carbon filter plate 20 in the water storage tank 2 perform dual purification of the cooling water. The perforated filter plate 19 can filter out larger particulate impurities, while the activated carbon filter plate 20 further adsorbs small particles, organic matter, and odors in the water to ensure the purity of the cooling water.

[0032] Furthermore, a front annular pipe 15 is installed in front of the partition plate 21, and a guide roller 14 is installed in front of the front annular pipe 15. The guide roller 14 provides stable guidance for the wire rod, ensuring that the wire rod maintains the correct position and posture when passing through the spray area, avoiding wire rod deviation, making spray cooling more uniform and effective, and also reducing friction between the wire rod and other internal components of the device, protecting the surface quality of the wire rod. A rear annular pipe 16 is installed behind the partition plate 21, and the guide roller 14 is installed behind the rear annular pipe 16. Water troughs are opened on both sides of the front annular pipe 15 and the rear annular pipe 16. Spray heads 17 are installed on both the front annular pipe 15 and the rear annular pipe 16. Multiple spray heads 17 are arranged in a symmetrical circular pattern, which can achieve all-round and uniform spray cooling of the wire rod. This uniform cooling method effectively avoids the problem of local cooling being too fast or too slow, greatly reduces the generation of internal thermal stress in the wire rod, reduces the risk of wire rod deformation and cracking, and improves product quality.

[0033] Specifically, pipe 18 is connected to the front annular pipe 15, and cooling water pipe 12 is connected to the rear annular pipe 16.

[0034] Please see the appendix Figure 6 As shown, the mixing chamber 3 has a mixing cavity 30 inside. A first slide 4 is installed on the front surface of the mixing chamber 3, and a second slide 5 is installed on the rear surface of the mixing chamber 3. Pull-out plates 29 are installed on both the first slide 4 and the second slide 5. The pull-out plates 29 have filter holes, which can perform preliminary sedimentation and filtration on the used cooling water to remove larger impurities in the water.

[0035] Specifically, a first pipe 11 is installed inside the mixing chamber 30, and a water pump 13 is installed on the rear surface of the main body 1. The output end of the water pump 13 is connected to the water storage tank 2 through a pipe. When the wire rod enters the front annular pipe 15, since the wire rod has just undergone rolling and other processes, it carries a large amount of heat energy. This heat energy is quickly absorbed by the cooling water, and the temperature of the cooling water will rise significantly in a very short time. The originally low-temperature water is heated into hot water at a higher temperature. The hot water enters the first slide 4 through the lower water tank and flows into the mixing box 3. Then, the annular pipe 16 is connected to the external cooling water pipe 12 to ensure that the water sprayed from the rear annular pipe 16 is always cooling water. The cold water flows into the mixing box 3 through the lower water tank at the rear, forming warm water in the mixing box 3. The water pump 13 is used to extract the warm water and send it into the front annular pipe 15. In this way, both the recycling of water resources and the gradual cooling of the wire rod are realized.

[0036] During use, the low-alloy welding wire rod, which is at a high temperature after rolling and other processes, first passes through the through hole 7 of the front baffle 6 and enters the equipment body 1. The guide roller 14 guides the wire rod, keeping it in the correct direction of travel, and smoothly enters the area of ​​the front annular tube 15. As the wire rod continues to travel, it passes through the detection hole 23 on the pressing block 22. When a wire rod of normal diameter passes through, the pressing block 22 is subjected to normal force; if the wire rod diameter is abnormal, the force on the pressing block 22 changes, triggering the first contact 24, the second contact 25, or the third contact 26 at different heights below. The audible and visual alarm 9, which is electrically connected to these contacts, will then sound an alarm, reminding the operator to adjust the rolling process in time and take appropriate measures.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
