The emergence and application of automotive hot forming technology have changed market demand. A car hot forming production line is generally equipped with 4-5 three-dimensional five axis laser cutting machines, and the market demand is developing explosively.
As of now, there are nearly 450 automotive hot forming production lines worldwide, and there are approximately 2000 sets of 3D five axis laser cutting machines produced along with supporting facilities. There are nearly 170 hot forming production lines in China, and approximately 700 sets of 3D five axis laser cutting machines are produced along with the supporting facilities.
Automobile manufacturers are fond of Thermoforming steel plates, and the demand for hot formed steel plates with higher yield strength is increasing. As a sharp tool for processing special-shaped surface parts, 3D five axis laser cutting machine plays an indispensable role in the industry.
The principle of 3D five axis laser cutting is to utilize the flexible and fast motion performance of industrial robots. Depending on the size of the workpiece being cut and processed by the user, the robot can be selected for front or reverse assembly to teach programming or offline programming for different products and trajectories. The sixth axis of the robot is loaded with fiber laser cutting heads to perform 3D cutting on irregular workpieces; The fiber laser cutting head is equipped with a follow-up device and a light path transmission device. The laser is transmitted to the cutting head using optical fibers, and then focused using a focusing system. Multiple sets of focusing systems have been developed for cutting various three-dimensional metal plates of different thicknesses in multiple directions.
In addition to the high applicability of cutting with a wide range of materials and complex shapes, coupled with suitable devices, machines can be developed with greater performance and applications, just like the HGLASER AUTOBOT3015 3D Five Axis Laser Cutting Intelligent Equipment for Automotive Hot Formed Parts:
In addition to completing three-dimensional cutting of workpieces, it can also be used for flat cutting. At the same time, the welding module can be switched on this platform, which can be extended to a laser welding platform to realize one machine with multiple functions. 24 hour uninterrupted and stable production, suitable for mass production.
1. In traditional joint robotic hands, each joint axis is interconnected and arranged sequentially from the fixed base of the robotic arm to the processing head, resulting in accumulated accuracy errors and geometric growth of the final processed product error. The axes of the three-dimensional five axis machining machine are independent of each other, and the gantry dual drive structure has high stability, which can ensure long-term high-speed, high-precision and stable cutting.
2. The structure of the gantry dual drive system features an integrated welded and formed bed with a high rigidity and dynamic response crossbeam. At the same time, it is driven by a dedicated guide rail base and a double sided gear rack dual motor of a linear guide rail. The effective cutting width can reach 6 * 4.5m, and can even be customized according to production needs.
3. In addition, in the processing of automotive parts, there are advantages that other cutting machines cannot match, such as the design and manufacturing of automotive bodies, which greatly reduces the investment risk of mold development. They are mainly used for developing new vehicle models, online cutting, and production of deformation vehicles, such as cutting sample vehicle parts, cutting holes and trimming of body cover parts, cutting steering wheel holes, body wind deflectors, roof cover bracket holes, safety airbag components, hydraulic formed components, etc, It is also a popular equipment for Huagong Laser in the automotive manufacturing industry.
