Description

Technical Field

[0001] This utility model relates to the field of strip steel production line technology, specifically a two-dimensional cutting and welding platform for a high-precision laser welding machine in a strip steel production line. Background Technology

[0002] Thin steel sheets are widely used in many important fields, including basic construction, engineering machinery, transportation, energy and environmental protection, and national defense. For example, in the transportation sector, thin steel sheets are used in automobile manufacturing, requiring high strength, good processability, and impact energy absorption capacity. Furthermore, thin-gauge ultra-high-strength heat-treated steel sheets are key raw materials for large-scale equipment manufacturing. As equipment manufacturing develops towards larger, more advanced, and lighter designs, the demand for thin-gauge ultra-high-strength steel sheets continues to increase. The production and welding of thin strip steel also places increasingly higher demands on equipment precision. Traditional laser welding equipment, due to its lower precision, cannot form reliable welds on thin strip steel during continuous production, resulting in welding failures or insufficient weld strength. This leads to low welding success rates and even strip breakage on the production line, causing losses and impacting production. Utility Model Content

[0003] The purpose of this invention is to provide a two-dimensional cutting and welding platform for a high-precision laser welding machine in a strip steel production line, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-dimensional cutting and welding platform for a high-precision laser welding machine in a strip steel production line, comprising a crossbeam support, a track crossbeam, and a track trolley. Track crossbeams are installed on both sides above the crossbeam support, and a track trolley is installed above the track crossbeams. A first cylinder is installed on the outer side of the track trolley. A laser welding head is installed below the first cylinder on the left side, and a laser cutting head is installed below the first cylinder on the right side. A support frame is installed in the middle position below the crossbeam support. A worktable is installed on the inner side above the support frame, and a fixed bracket is installed on the outer side above the support frame. Multiple second cylinders are installed on the inner wall of the fixed bracket, and the lower parts of the multiple second cylinders are all installed above a pressing plate.

[0005] Preferably, the crossbeam support is U-shaped, and the crossbeam support and the track crossbeam are fixedly connected.

[0006] Preferably, the track beam and the track trolley are slidably connected, and the track trolley and the first cylinder are fixedly connected.

[0007] Preferably, the output end of the first cylinder on the left is fixedly connected to the laser welding head, and the output end of the first cylinder on the right is fixedly connected to the laser cutting head.

[0008] Preferably, the two track beams are arranged parallel to each other, and the track beams and the first cylinder are arranged perpendicular to each other.

[0009] Preferably, the support frame is fixedly connected to the worktable and the fixed bracket, and the worktable and the fixed bracket are arranged perpendicular to each other.

[0010] Preferably, the fixed bracket is fixedly connected to the second cylinder, and the output end of the second cylinder is fixedly connected to the pressing plate.

[0011] Preferably, the pressing plate and the worktable are arranged parallel to each other.

[0012] Preferably, the pressing plate has a rectangular structure, and a rubber pad is provided below the pressing plate.

[0013] Preferably, the rubber pad and the pressing plate are tightly fitted together.

[0014] Compared with existing technologies, the beneficial effects of this utility model are:

[0015] By setting up a crossbeam support, a track beam, and a track trolley, when processing the welded strip steel, the strip steel to be welded is first placed on the worktable. The second cylinder is activated, moving the pressing plate downwards. The rubber pad under the pressing plate fits tightly against the strip steel surface, fixing the strip steel to the worktable and preventing displacement during welding or cutting. Next, the control panel sends a command to activate the left-side first cylinder, which moves the laser welding head downwards to maintain an appropriate distance from the strip steel surface. Then, the control panel sends another command, and the track trolley, driven by a servo motor, slides along the track beam. The track trolley moves the laser welding head connected to the left-side first cylinder, emitting laser light to weld the strip steel. During welding, the track trolley moves slowly along the track beam, ensuring the continuity and precision of the welding trajectory. When processing cut strip steel, the same operation is performed, ensuring the continuity and precision of the cutting trajectory, reducing weld seam breakage, and significantly lowering production costs.

[0016] The device achieves automatic fixing and release of strip steel through the coordinated operation of the control panel and the second cylinder, reducing manual operation and improving production efficiency. In addition, the equipment integrates laser welding and laser cutting functions, which can meet the various needs of strip steel production lines and improve equipment utilization.
