Description

Technical Field

[0001] This application relates to the field of steel processing equipment technology, specifically a welding device for steel. Background Technology

[0002] Steel structure engineering refers to structures primarily made of steel, mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets, and it is one of the major types of building structures. Currently, welding is commonly used to assemble several steel plates into H-shapes or other specific shapes, and this welding process is widely used in the steel processing industry.

[0003] Currently, most steel welding processes are carried out using manual continuous welding. However, this method has many drawbacks. On the one hand, manual welding requires welders to concentrate for a long time, resulting in high labor intensity and high labor costs. On the other hand, manual welding is inefficient, and the welding quality is greatly affected by factors such as the welder's skill level and fatigue level, making it difficult to guarantee the stability and consistency of welding quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a steel welding device that offers advantages such as high-efficiency and high-quality steel welding, solving the problems of high cost and low efficiency in existing manual steel welding.

[0005] To achieve the above objectives, this application provides the following technical solution: a welding device for steel, comprising a base, two symmetrical fixing plates fixedly connected to the inner side of the base, a welding power supply device fixedly connected to the upper surface of each of the two fixing plates, an angle adjustment assembly provided on the upper surface of each of the two fixing plates, a fixing seat provided above each of the two fixing plates, a hydraulic telescopic rod fixedly connected to the outer surface of each of the two fixing seats, a mounting plate fixedly connected to the output end of each of the two hydraulic telescopic rods, the mounting plate and the welding power supply device being electrically connected, a welding torch fixedly connected to the outer surface of each of the two mounting plates, two sets of clamping assemblies provided on the inner side of the base, and guide telescopic rods fixedly connected to the outer surface of each of the two fixing seats, with the telescopic end of the guide telescopic rod fixedly connected to the outer surface of the mounting plate.

[0006] The above solution enables automated welding of transported steel by setting up welding power supply equipment, mounting plates, and welding torches. This reduces manual operation and lowers labor costs. Furthermore, the extension length and angle of the welding torch can be adjusted by the angle adjustment component and hydraulic telescopic rod, allowing for adjustments to the height and angle of the welding torch according to actual conditions. This improves welding quality and enhances the applicability of the welding process. Moreover, the automated welding process eliminates the need for continuous manual welding, resulting in fast welding speeds and significantly improved production efficiency.

[0007] Furthermore, two symmetrical bearing seats are fixedly connected to the inner side of the machine base, and a drive wheel is rotatably connected to the inner wall of the two bearing seats. A drive motor is fixedly embedded on the outer surface of one of the bearing seats, and the output end of the drive motor is fixedly connected to one end of the drive wheel. A first driven roller is rotatably installed on the inner side of the machine base, and a second driven roller is rotatably installed on the inner side of the machine base.

[0010] The above scheme, through the use of cylinders, fixed frames, and rollers, can provide stable pressure to the conveyed steel, ensuring the stability of the steel during welding. Furthermore, the steel can be continuously conveyed while the rollers can compress it, thereby achieving stable and continuous welding.

[0011] Furthermore, the middle part of the roller is concave.

[0012] The above-mentioned design allows the rollers to be adapted to both T-shaped and H-shaped steel, thereby improving the practicality of the welding device.

[0013] Furthermore, the angle adjustment assembly includes two vertical plates, the bottom surfaces of which are fixedly connected to the upper surface of the fixed plate, and the inner walls of the two vertical plates are rotatably connected to a rotating shaft, and the inner wall of the fixed base is fixedly connected to the outer surface of the rotating shaft.

[0014] The above solution, by setting up a rotating shaft, can drive the fixed seat to adjust its angle, thereby allowing the welding torch to be adjusted according to the actual needs on site, thus improving welding quality and enhancing the applicability of the welding process.

[0015] Furthermore, one end of the rotating shaft extends through the outer surface of the vertical plate to the outside of the vertical plate, and a first sprocket is fixedly connected to one end of the rotating shaft. An extension shaft is rotatably connected to the inner wall of one of the vertical plates. A first servo motor is fixedly embedded on the outer surface of one of the vertical plates, and the output end of the first servo motor is fixedly connected to one end of the extension shaft. A second sprocket is fixedly connected to the outer surface of the extension shaft. A chain is sleeved on the outside of the second sprocket, and the second sprocket and the first sprocket are connected by the chain drive.

[0016] The above scheme, through the coordinated action of the first servo motor, extension shaft, first sprocket, second sprocket, and chain, enables the shaft to rotate automatically, thereby facilitating operation, reducing labor costs, and improving production efficiency.

[0017] Furthermore, the clamping assembly includes a mounting base fixedly connected to the inner side of the machine base. The outer surface of the mounting base has two T-shaped guide grooves. The inner walls of the two T-shaped guide grooves are slidably connected to a movable plate. The outer surface of the movable plate is fixedly connected to a connecting frame. The inner side of the connecting frame is rotatably mounted with two pressure rollers.

[0018] The above scheme, by setting the T-shaped guide groove, can limit and guide the movement of the moving plate, thereby enabling the moving plate and pressure roller to move in a precise direction, ensuring that the pressure roller can stably squeeze the steel.

[0019] Furthermore, a lead screw is rotatably connected to the inner wall of the mounting base, a second servo motor is fixedly embedded in the inner side of the mounting base, the output end of the second servo motor is fixedly connected to one end of the lead screw, a connecting seat is threaded onto the outer surface of the lead screw, and the bottom surface of the connecting seat is fixedly connected to the upper surface of the moving plate.

[0020] Through the above scheme, the aforementioned setting of the lead screw and the second servo motor can drive the moving plate to drive the pressure roller to squeeze the steel, thereby improving the stability and quality of welding.

The above-mentioned roller 20 design can be adapted to T-shaped steel and H-shaped steel, thereby improving the practicality of the welding device.

[0034] Please see Figure 1 , Figure 2 and Figure 5The clamping assembly 9 includes a mounting base 901 fixedly connected to the inner side of the base 1. Two T-shaped guide grooves 902 are formed on the outer surface of the mounting base 901. A movable plate 903 is slidably connected to the inner wall of the two T-shaped guide grooves 902. A connecting frame 904 is fixedly connected to the outer surface of the movable plate 903. Two pressure rollers 905 are rotatably mounted on the inner side of the connecting frame 904.

[0035] This embodiment of a steel welding device enables automated welding of transported steel by means of a welding power supply device 3, a mounting plate 7, and a welding torch 8. This reduces manual operation and lowers labor costs. Furthermore, the extension length and angle of the welding torch 8 can be adjusted by the angle adjustment component 4 and the hydraulic telescopic rod 6. This allows for adjustment of the height and angle of the welding torch 8 according to actual conditions, improving welding quality and enhancing the applicability of the welding process. Moreover, the automated welding process does not require continuous manual welding, and the welding speed is fast, greatly improving production efficiency.

[0036] It should be noted that the welding power supply device 3, hydraulic telescopic rod 6, welding torch 8, cylinder 18, first servo motor 405, and second servo motor 907 in this welding device are all electrically connected to an external controller. As a result, the operator can fully operate the welding device by controlling the controller. This method greatly reduces manual operation, lowers labor costs, and improves welding efficiency.

[0037] The working principle of the above embodiment is as follows: When using this device, the steel is first placed on the first driven roller 14 and the second driven roller 15 by hoisting, with one end of the steel placed on the drive wheel 12. At this time, the cylinder 18 is started to drive the roller 20 to squeeze the upper part of the steel. Then, the second servo motor 907 is started to drive the lead screw 906 to rotate. At this time, the lead screw 906 can drive the connecting seat 908 and the moving plate 903 to move. Under the limiting guidance of the T-shaped guide groove 902, the moving plate 903 can move in a precise direction. Then, while the moving plate 903 is moving, it drives the pressure roller 905 to squeeze and fix the side of the steel. Then, the drive motor 13 can drive the steel to move in a precise direction. The drive wheel 12 rotates, thereby driving the steel to be conveyed. At this time, under the action of the pressure wheel 905 and the roller 20, the steel can be conveyed while being squeezed. Finally, the first servo motor 405 can drive the extension shaft 404 to rotate. Under the transmission of the second sprocket 406, the first sprocket 403 and the chain 407, the rotating shaft 402 can rotate. At this time, the rotating shaft 402 can drive the fixed seat 5 to rotate, thereby adjusting the welding angle of the welding torch 8. Then, under the action of the hydraulic telescopic rod 6, the position of the welding torch 8 can be adjusted. Thus, the height and angle of the welding torch 8 can be adjusted according to the actual situation, improving the welding quality and enhancing the applicability of the welding.
