Description

Technical Field

[0001] This utility model relates to a welding cooling water tank, belonging to the field of welding tooling technology. Background Technology

[0002] In the field of mechanical manufacturing, welding of shaft parts is a key process, widely used in various mechanical equipment such as screw conveyors and mixing equipment. During the welding process of shaft parts, the rapid increase in local temperature and uneven heat distribution at the welding point easily generate significant thermal stress. This thermal stress not only leads to defects such as deformation and cracks in the welded shaft parts, but also significantly reduces the mechanical properties and service life of shaft parts such as screw shafts, thereby affecting the operational stability and reliability of the entire mechanical equipment.

[0003] Currently, traditional methods mostly involve natural cooling or simple spray cooling after welding. Natural cooling is too time-consuming and cannot effectively control temperature changes during the welding process, making it difficult to meet the demands of high-efficiency production. While spray cooling can accelerate the cooling rate, the coolant only acts on the surface of the shaft parts, failing to achieve all-round, uniform cooling of the shaft. This still cannot prevent the performance degradation of shaft parts caused by thermal stress concentration. In addition, existing cooling methods lack effective designs for cooling the rotating parts of shafts, making it difficult to ensure uniform heating of all parts of the welded area. Neither natural cooling nor spray cooling can cool the shaft to be welded in a timely manner during the welding process, and neither can achieve efficient and uniform cooling. Utility Model Content

[0004] The purpose of this invention is to provide a welded cooling water tank to solve the above-mentioned technical problems.

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

[0006] A welding cooling water tank includes a water tank mounted on support legs and a welding positioner disposed on one side of the water tank; a support roller frame for supporting the welded workpiece is disposed inside the water tank; one end of the welded workpiece is located on the support roller of the support roller frame, and the other end is connected to the chuck of the welding positioner through a connecting shaft.

[0007] A further improvement to the technical solution of this utility model is that baffles are provided on the inner sides of both ends of the water tank, and through grooves are provided on the baffles.

[0008] A further improvement to this utility model is that a drain outlet is provided at the bottom of the water tank, and the drain outlet is sealed with a plug.

[0009] A further improvement to the technical solution of this utility model is that 2-3 drain outlets are provided, and the drain outlets are distributed along the axial direction of the water tank.

[0010] A further improvement to the technical solution of this utility model is that the cross-section of the water tank is semi-circular.

[0011] A further improvement to the technical solution of this utility model is as follows: the welding positioner includes a frame, a power mechanism and a speed transmission mechanism mounted on the frame; the chuck is mounted on the output shaft of the speed transmission mechanism.

[0012] A further improvement to the technical solution of this utility model is that the chuck is a three-jaw chuck.

[0013] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows:

[0014] This invention relates to a welding cooling water tank, which allows welded shaft components to rotate within the tank, which is filled with coolant. During the welding process, the tank provides timely cooling, ensuring uniform heating across all areas and preventing performance degradation of the screw shaft due to thermal stress.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] This utility model is a welding cooling water tank. When the welded parts are placed in the water tank, they can be cooled in real time during the welding process, effectively solving the problem of deformation of the welded parts.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the welding cooling water tank includes a water tank 1, support legs 2, and a welding positioner 4. The water tank 1 can be filled with water, coolant, or a mixture of water and coolant. The water tank is fixedly mounted on the support legs 2, with at least two support legs 2 spaced apart to ensure effective and stable support for the water tank 1. A welding positioner is located on one side of the water tank 1. The welding positioner is used to rotate the workpiece during the welding process and is suitable for welding components on a spiral shaft, where rotation of the spiral shaft is required during welding.

[0024] A roller support frame 3 is installed inside the water tank 1. The roller support frame 3 has two rollers rotatably mounted on it, typically two parallel rollers. These rollers can rotate on the roller support frame 3. The rollers on the roller support frame 3 lift and rotate the spiral shaft, which, placed on the rollers of the roller support frame 3, can slowly rotate under the drive of the welding positioner. Specifically, one end of the weldment is placed on the roller of the roller support frame 3, and the other end of the weldment is connected to the chuck of the welding positioner 4 via a connecting shaft 5.

[0025] like Figure 1 As shown, baffles 6 are provided on the inner sides of both ends of the water tank 1, and through grooves are provided on the baffles 6. In specific implementations, the cross-section of the water tank 1 is preferably set as a semi-circle.

[0026] like Figure 2 As shown, a drain outlet 7 is provided at the bottom of the water tank 1. During normal use, the drain outlet 7 is sealed with a plug. When the coolant needs to be replaced, the plug is removed, and the coolant in the water tank 1 is drained through the drain outlet 7 before new coolant is added. Multiple drain outlets 7 are typically provided, usually 2-3, distributed axially along the bottom surface inside the water tank 1. The multiple drain outlets allow for rapid drainage.

[0027] The welding positioner used in this technical solution was purchased and is a commonly used piece of equipment in welding. During use, the rotation speed of the welding positioner can be adjusted as needed.

[0028] The welding positioner 4 mainly consists of a frame, a power mechanism, and a speed transmission mechanism. The power mechanism is externally powered and drives the speed transmission mechanism, which mounts the chuck on its output shaft. In practice, the chuck is typically a three-jaw chuck. The output speed of the welding positioner can be adjusted as needed.

[0029] When using the water tank of this utility model, two-thirds of the spiral shaft is generally immersed in cold water. The thermal conductivity of metal is used to cool the welded parts, so that the temperature of the heat-affected zone of the weld is uniform, thereby enhancing the metal restraint, reducing the movement of metal atoms near the heat source, and ultimately achieving the purpose of controlling the welding deformation of the spiral shaft.

[0030] During use, a sealing box needs to be installed on the side plate of the water tank on one side of the welding positioner, and an exposed skeleton rotary oil seal needs to be installed in the sealing box to ensure that the cooling liquid does not flow out of the water tank. Mount the spiral shaft to be welded onto the roller support frame at one end, and connect the other end to the connecting shaft. Use shims to adjust the welding positioner to the same height as the center of the spiral shaft, so that the three-jaw chuck of the welding positioner clamps the connecting shaft; pour cold water and rust inhibitor into the water tank until the water depth reaches the upper 2 / 3 of the spiral shaft circumference.

[0031] This invention ensures that a portion of the spiral shaft remains immersed in the cooling solution throughout the welding process, allowing for timely cooling and ensuring uniform heating across the shaft. This prevents performance degradation caused by thermal stress. Applying this invention to the welding of spiral shafts improves product quality and performance.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
