Description

Technical Field

[0001] The invention relates to the technical field of electric welding machines, in particular to an electric welding machine with a constant temperature cooling function. Background Art

[0002] Electric welding machines can be divided into two types according to the type of output power: AC welding machines and DC welding machines. A DC welding machine is actually a high-power rectifier with positive and negative poles. When AC power is input, it is transformed by a transformer and then rectified by a rectifier, and then outputs power with a falling external characteristic.

[0003] In addition, electric welders can also be subdivided into various types according to different application fields and welding methods, such as AC arc welders, argon arc welders, carbon dioxide shielded welders, butt welders, spot welders, submerged arc welders, etc. These different types of electric welders have their own characteristics in welding process, welding materials, welding efficiency, etc., and can meet the welding needs of different fields. ; There are still the following defects in specific use: 1. Heat loss will cause the temperature of the welding area to drop, thus affecting the fusion and strength of the weld. Poor fusion of the weld may result in a loose weld joint and pose a safety hazard. In addition, in order to compensate for heat loss, it may be necessary to increase the welding current or extend the welding time to ensure that the weld reaches the required fusion and strength. This will increase energy consumption and reduce welding efficiency.

[0004] 2. Local overheating may cause changes in the structure of the weld metal, such as grain coarsening, which reduces the strength and toughness of the weld. Thermal stress is one of the main causes of welding deformation. When the weld is locally overheated, the area will expand thermally, while the surrounding area will not expand in time, thus generating thermal stress. When the weld cools, the area subjected to thermal stress will shrink, causing the weld to deform.

[0023] The complete working principle and steps of the above embodiment are as follows: Initial qualification: 1. Preparation for welding machine work Before starting work, first of all, it is necessary to ensure that the power connection of the welding machine body 1 is stable, and the parameters such as voltage and current meet the welding requirements. The operator needs to wear protective equipment, such as welding masks, protective gloves, work clothes, etc., to prevent the strong light, high-temperature spatter and harmful gases generated during welding from causing harm to the person. Then, according to the type, thickness and welding requirements of the material to be welded, select the appropriate welding rod 12 and electrode 13. The selection of welding rod 12 is directly related to the strength and quality of the weld, while the electrode 13 is responsible for conducting electrical energy to the welding rod to trigger the welding reaction.

[0024] 2. Startup and setting of welding machine body 1 The welding machine body 1 is the core of the entire welding system, which is responsible for converting the input electrical energy into an electrical energy form suitable for welding. Before starting the welding machine body 1, the welding current, welding time and other parameters need to be set through the control panel. For different types of electrodes and welding tasks, the setting of these parameters is crucial. For example, for thinner metal sheets, a smaller current and a shorter welding time are required to avoid excessive heat-affected zone causing material deformation; for thicker metal parts, the current needs to be increased and the welding time needs to be extended to ensure the penetration and strength of the weld.

[0025] 3. Operation of the rotating handle 11 and installation of welding rods The rotating handle 11 is the part that the operator directly controls. It allows the operator to flexibly adjust the position and angle of the welding rod 12 during the welding process to adapt to welds of different shapes and positions. Before use, it is necessary to ensure that the rotating handle 11 is firmly connected to the welding machine body 1, and at the same time check whether it rotates smoothly to ensure the accuracy and stability of the welding operation. The welding rod 12 is installed on the rotating handle 11 through a specific clamp. During installation, it is necessary to ensure that the welding rod 12 is in close contact with the electrode 13 so that the current can be smoothly transmitted to the tip of the welding rod 12.

[0026] 3. Welding process When everything is ready, the operator presses the start button on the welding machine body 1, and the current flows to the welding rod 12 through the electrode 13. Under the action of the current, the tip of the welding rod 12 quickly heats up to a molten state, and a strong arc light is generated. During this process, the welding core and the coating in the welding rod 12 undergo complex physical and chemical changes, releasing a large amount of heat and gas, which is used to melt the metal base material to be welded to form a molten pool. Under the blowing force of the arc, gravity, and manual adjustment of the operator, the molten metal in the molten pool gradually fills the weld and solidifies to form a firm metal connection.

[0027] 4. Control and monitoring of welding quality During the entire welding process, the operator needs to pay close attention to the formation of the weld, and control the width, depth and appearance quality of the weld by adjusting the welding current, the moving speed of the electrode 12 and the angle of the rotating handle 11. At the same time, it is also necessary to avoid the generation of welding defects, such as slag inclusions, pores, cracks, etc. These defects will not only affect the strength of the weld, but may also cause safety hazards in future use. Therefore, when necessary, welding auxiliary equipment, such as welding gun preheating devices, gas protection devices, etc., can be used to optimize the welding environment and improve the welding quality.

[0028] 5. Completion of work and equipment maintenance After the welding task is completed, the power supply of the welding machine body 1 should be cut off first, and the equipment should be cleaned and maintained after it is completely cooled. This includes cleaning the residue of the welding rod 12, checking the wear of the electrode 13 and the rotating handle 11, and cleaning the dust and debris inside the welding machine body 1. Regular maintenance and care can extend the service life of the welding machine body 1 and ensure that it is always in good working condition; When using: The welding fire focusing mechanism is used to guide the sparks and spatters generated during welding to the welding point. Step 2: like Figure 3 to Figure 4 As shown, when the operator controls the welding direction of the welding rod 12 by twisting and adjusting the rotating handle 11 to weld the object, the operator first presses the controller switch fixedly connected to the top of the telescopic cylinder 22, so that the controller switch drives the inner rod 28 to move to one side and extend, so that the gathering plate 23 fixedly connected to the outer wall of one end of the inner rod 28 moves together with the inner rod 28, and at the same time, with the movement of the inner rod 28, the crank 25 on the outer wall of one end of the short rod 24 is pulled downward to be horizontal, and at the same time, the downward deflection of the crank 25 pulls the connecting rod 26 rotatably connected at one end thereof to be deflected downward to be horizontal, so that the sparks generated during the welding process are covered and gathered by the opposite horizontal movement of the symmetrically arranged gathering plates 23; Stress balancing mechanism to ensure that both sides of the weldment can be adequately heated and cooled so that the weldment is heated evenly 3 steps: like Figures 5 and 6 As shown in the figure, when the telescopic cylinder 22 moves horizontally and extends, the toothed bar 31 fixedly connected to its outer wall will move along with it, and then the small gear 32 meshing with it will rotate with the movement of the toothed bar 31, and the large gear 33 meshing with its left outer wall will also rotate with the rotation of the small gear 32, so that the connecting rod 38 rotatably connected to the outer wall of one side of the large gear 33 will swing with the rotation of the large gear 33, and the bottom obstacle column 37 fixedly connected to the outer wall of one end of the connecting rod 38 will be pushed and connected to the fixed wall with the swing of the connecting rod 38. The outer rod 35 on the outer wall of the fixed shaft 36 swings, and the swing of the outer rod 35 also pushes the inner shaft 34 clamped at its top end to drive the outer rod 39 to swing downward, so that the fixed plate 310 connected to the outer wall of the end of the outer rod 39 away from the inner shaft 34 will rotate with the rotation of the outer rod 39, thereby the placement plate 311 fixedly connected to the outer wall of the fixed plate 310 will deflect with the rotation of the fixed plate 310, thereby the objects placed on the inner surface of the placement plate 311 will be heated evenly on both sides of the welded parts as the placement plate 311 flips; The welding seat vibration mechanism is used to generate vibration and impact force to eliminate and reduce the residual stress generated in the welding area. 4 steps: like Figures 7 and 8 As shown, when the fixed disk 310 deflects, the turning handle 41 connected to the outer wall of one side thereof will rotate with the swing of the fixed disk 310, so that the barrier disk 43 connected to the outer wall of one end of the turning handle 41 will rotate, so that the protrusion provided on the outer wall of the barrier disk 43 will push the sleeve block 46 that contacts the outer wall, so that the downward movement of the sleeve block 46 will drive the rotating block 44 fixedly connected to one end thereof to rotate on the inner wall of the bottom end of the support column 42, so that the striking block 45 fixedly connected to one end of the rotating block 44 will move upward and swing, thereby realizing the hammering of the outer wall of the bottom end of the welding object; Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
