Description

Technical Field

[0001] The invention relates to the technical field of roll forming, and in particular to an online three-dimensional bending forming device and method for high-strength steel roll forming. Background Art

[0002] Currently, when automobile parts manufacturers produce three-dimensional curved profiles (such as guide groove processing), they mostly first process the sheet material into the required straight profile by roll forming, then cut it into the required length, and then bend the straight profile into a three-dimensional curved profile by a stretch-bending device.

[0003] The existing technology uses rolling equipment and bending equipment to complete the production of this guide groove method. Since the production efficiency of the bending equipment is inconsistent with that of the rolling forming, the semi-finished products need to be stored, and they need to be loaded during the bending process. This will reduce the utilization rate of the enterprise's equipment and cause waste. On the other hand, it is necessary to manually load the bending equipment again, which increases the production cost. In addition, the manual loading production efficiency is low, which is not conducive to the development of the enterprise. Since there are clip marks on the head of the bent profile, a part of the straight section of the head needs to be sawed, which greatly reduces the material utilization rate.

[0004] Therefore, technicians in this field are committed to developing an online three-dimensional bending forming device and method for high-strength steel roll forming, which is directly connected to the discharge end of the roll forming machine, and realizes the three-dimensional bending forming of the guide groove online, thereby improving production efficiency and material utilization, reducing the labor intensity of workers and production costs, and has good application prospects.
