Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology for steel strips, and more specifically, to a strip seam welding device for a hot-dip galvanizing production line for steel strips. Background Technology

[0002] Hot-dip galvanizing of steel strip is a process in which steel strip is immersed in molten zinc to form a zinc coating. The temperature of the zinc bath affects the quality of the coating. It is available in continuous and batch galvanizing methods and is used in construction and other fields to make the steel strip strong and corrosion-resistant. Steel strip seam welding equipment uses roller electrodes to apply pressure and electricity for welding. It is fast and produces high strength and is used in the manufacture of metal containers to ensure reliable and stable connections.

[0003] Publication No. (CN220679872U) discloses a strip seam welding device for a hot-dip galvanizing production line, including a support frame. A transmission roller is movably connected evenly to the upper part of the inner cavity of the support frame. A transmission shaft is fixedly connected to the middle of the inner cavity of the transmission roller. A driving device is located on the left side of the front end face of the support frame and is movably connected to the left transmission shaft. Vertical plates are evenly fixedly connected to the left and right sides of the upper end face of the support frame. A first servo motor is fixedly connected to the left end face of the rear left vertical plate. The end of a first lead screw is movably connected to the left end face of the rear right vertical plate. Moving blocks are sleeved on the outside of the first lead screw and the limiting rod. Locking devices are fixedly connected to the opposite faces of the moving blocks. A welding device is located at the lower part of the support frame. This device has a simple structure, is easy to operate, and effectively improves production efficiency.

[0004] However, the strip seam welding device in this hot-dip galvanizing production line has the following drawbacks: Weld slag will appear at the weld joint of the steel strip after welding. In the hot-dip galvanizing process, a uniform and dense zinc coating needs to be formed on the surface of the steel strip to achieve functions such as corrosion protection. The presence of weld slag will hinder the uniform adhesion of the zinc liquid to the weld joint, resulting in uneven zinc coating thickness, reduced adhesion, and even missed galvanizing. Furthermore, it is impossible to clean the weld slag immediately after welding. The weld slag adheres to the surface of the weld joint, forming protrusions, burrs, or uneven surfaces, severely affecting the appearance quality of the steel strip. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a strip seam welding device for a hot-dip galvanizing production line of steel strip, so as to solve the problem that the welding slag that appears after welding cannot be cleaned at the same time after welding in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a strip seam welding device for a hot-dip galvanizing production line, comprising...

[0007] The system includes a bracket, a first motor, and a second motor. The first motor has a lead screw fixedly connected to its drive end, and a fixed bracket is threaded onto the outside of the lead screw. The bracket has a support block fixedly connected to its outside.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a strip seam welding device for a hot-dip galvanizing production line, including a support 1, a first motor 2, and a second motor 6. The drive end of the first motor 2 is fixedly connected to a lead screw 4, and the lead screw 4 is externally threaded to a fixing frame 5. The support block 3 is externally fixedly connected to the support 1. The drive end of the second motor 6 is fixedly connected to a rotating column 7, and a connecting plate 10 is slidably connected to the inner wall of the rotating column 7. A locking pin 11 is rotatably connected to the end of the connecting plate 10 away from the rotating column 7. A cleaning plate 12 is externally fixedly connected to the locking pin 11. The second motor 6 is externally fixedly connected to the outside of the fixing frame 5, the first motor 2 is externally fixedly connected to the outside of the supporting block 3, the lead screw 4 is externally rotatably connected to the inner wall of the supporting block 3, and the fixing frame 5 is externally slidably connected to the outside of the support 1.

[0025] By starting motor 2, the lead screw 4 in the support block 3 is rotated, causing the fixed frame 5 to move and the welding head to be adjusted to a suitable position for welding the steel strip. This allows for welding adjustments based on the welding point, resulting in a simple structure, low cost, and significant effect. At this time, by starting motor 6, the rotating column 7 is rotated, causing the cleaning plate 12 to clean the welding slag generated after welding.

[0026] Example 2: Based on Example 1, in order to make it easier to swing the cleaning plate 12 to clean stubborn welding slag, a pressure plate 9 is fixedly connected to the end of the connecting plate 10 away from the locking pin 11, and an S-shaped elastic element 8 is fixedly connected to the end of the pressure plate 9 away from the connecting plate 10. A sliding groove 13 is opened on the inner wall of the rotating column 7, and the outside of the S-shaped elastic element 8 is fixedly connected to the inner wall of the sliding groove 13. The outside of the pressure plate 9 is slidably connected to the inner wall of the sliding groove 13.

[0027] During the welding process of steel strip, a large amount of welding slag will adhere to the weld joint after welding. At this time, the motor 6 is started, which drives the rotating column 7 to rotate. The cleaning plate 12 in the rotating column 7 will clean the welding slag. When the cleaning plate 12 comes into contact with more stubborn welding slag, the cleaning plate 12 can impact the stubborn welding slag by swinging, making it easier to clean the welding slag and improving work efficiency.

[0028] Example 3: Based on Example 2, in order to make the cleaning plate 12 adhere closely to the welding slag for effective cleaning, the end of the S-shaped elastic element 8 away from the pressure plate 9 is fixedly connected to the inner wall of the rotating column 7. The inner wall of the cleaning plate 12 is provided with a movable groove 14, the inner wall of the bracket 1 is provided with a collection groove 15, the outer side of the pressure plate 9 is slidably connected to the inner wall of the rotating column 7, and the end of the connecting plate 10 away from the pressure plate 9 is movably connected to the inner wall of the movable groove 14.

[0029] When the cleaning plate 12 comes into contact with thick or stubborn welding slag, the cleaning plate 12 will be under pressure. The pressure plate 9 connected by the connecting plate 10 will squeeze the S-shaped elastic element 8. The S-shaped elastic element 8 will deform under pressure, which satisfies the cleaning plate 12 to clean the stubborn and thick welding slag.

[0030] The working process of this utility model is as follows:

[0031] First, by starting motor 2, the lead screw 4 in support block 3 is rotated, causing the fixing frame 5 to move and adjust the welding head to a suitable position for welding the steel strip. This allows for adjustments based on the welding point, resulting in a simple structure, low cost, and significant effect. During the welding process, a large amount of weld slag will adhere to the weld joint after welding. At this point, starting motor 6 drives the rotating column 7 to rotate. The cleaning plate 12 in the rotating column 7 will then clean the weld slag. When the cleaning plate 12 comes into contact with thicker or stubborn weld slag... At this time, the cleaning plate 12 will be under pressure, and the pressure plate 9 connected to the connecting plate 10 will squeeze the S-shaped elastic element 8. The S-shaped elastic element 8 will deform under pressure, which satisfies the cleaning plate 12 to clean the stubborn and thick welding slag. When the rotating column 7 rotates, the cleaning plate 12 will swing outside the connecting plate 10 with the locking pin 11 as the fulcrum. When the cleaning plate 12 comes into contact with the stubborn welding slag, the cleaning plate 12 can cause a certain impact on the stubborn welding slag by swinging, making it easier to clean the welding slag and improving work efficiency.
