Laser Cutting and Bending of High-Strength Steel Plates 高强板上横梁激光下料折弯加工，材质700，厚度4mm。

Recently, JULONG STEEL custom-manufactured a batch of 4mm-thick, 10-meter-long crossbeams for dump semi-trailers for a domestic specialty vehicle manufacturer. The project required the precise drilling of mounting holes in strict accordance with the drawings, entailing high manufacturing standards and strict dimensional control.

近日居龙钢铁为国内专用车企定制加工一批4mm厚，长度10米的自卸半挂车上横梁。同时要完全按图纸预留工艺安装孔，加工要求高，尺寸必须严格控制。

High-efficiency laser cutting is used to minimize material deformation and pre-cut the required process holes.

采用高效激光切割下料，减少材质变形量并提前将预留工艺孔切割好。

Using a 12-meter, 4,000-ton fully CNC press brake designed and manufactured in-house by JULONG STEEL, we carefully match the upper and lower dies to achieve one-step bending and forming, ensuring machining precision.

利用居龙钢铁自主设计制造12米4000吨全数控折弯机，匹配好上下模，一次性折弯成型，保证加工精度。

The product passed the customer inspection on the first attempt. After final assembly, the vehicle fully met the design specifications and improved production efficiency.

客户检验一次性通过验收，整车组装后，完全达到设计要求，提高生产效率。

JULONG STEEL is currently capable of bending full-size sheets of various specifications up to 12 meters in length. We operate a 12-meter, fully CNC-controlled 4,000-ton press brake developed in-house, as well as a 12-meter, 2,000-ton LVD-HD press brake from Belgium, both equipped with specialized CNC systems from the Dutch company DELEM. German linear encoders provide real-time detection, feedback, and correction, along with full closed-loop control. The machines feature multi-step programming capabilities, enabling automated operation to complete multi-step parts in a single pass, thereby improving production efficiency.

居龙钢铁目前可加工12米以内各种规格整板折弯。我们拥有一台自主研制12米全数控4000吨折弯机和一台黄锻12米2000吨折弯机，都采用荷兰DELEM公司折弯机专用数控系统，德国光栅尺实时检测反馈校正、全闭环控制，具有多工步编程功能，可实现多自动运行，完成多工步零件一次性加工，提高生产效率。

In the cold-forming of wear-resistant and high-strength steel plates, JULONG STEEL has continuously developed a set of highly efficient and practical processing techniques that effectively address cracking issues during plate bending. The company provides custom processing services to clients both domestically and internationally, earning widespread recognition from its customers.

居龙钢铁在耐磨板、高强板冷弯加工中，不断探索出一套高效实用的加工工艺，可以解决钢板折弯中的开裂、变形等问题，为国内多家主机厂改装厂进行配套加工，得到客户一致认可。

居龙钢铁耐磨板、高强板折弯成型件广泛用于新型渣土自卸车、出口U型自卸半挂车，深受各大专用车厂的一致好评。欢迎来电洽谈合作！
