Bending of Dump Truck Side Beams 自卸车边梁折弯加工

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米以内各种规格折弯钢梁。我们拥有自主研制12米全数控4000吨折弯机，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。

车箱边框所用折弯件一般为3~6mm厚，一般应用在自卸车的车箱侧板边框上，材质为Q235、Q345、高强板。

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 issues such as cracking and deformation during bending. The company provides custom processing services for numerous domestic original equipment manufacturers (OEMs) and modification plants.

Julong Steel’s bent and formed components made from wear-resistant and high-strength steel plates are widely used in new-generation dump trucks and U-shaped dump semi-trailers for export. We welcome your inquiries regarding potential partnerships!

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。

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，欢迎来电洽谈合作！

Cold-formed components are currently widely used in vehicle manufacturing overseas, particularly in U-shaped dump trucks and U-shaped dump semi-trailers. By utilizing special steel plates and cold-forming processes, these components create high-strength, integrated vehicle bodies that meet requirements for lightweight design, energy efficiency, and environmental protection. Jilong Steel has established partnerships in China with Sinotruk, Shaanxi Automobile, Foton, FAW, SAIC, XCMG, and CIMC, fully dedicated to serving China’s high-end equipment manufacturing industry.

冷弯成型件目前在国外被广泛用于车辆生产制造中，尤其是在U型自卸车和U型自卸半挂车上，采用特殊钢板及冷弯加工工艺，打造高强度一体化车身，从而达到轻量化，节能环保的要求，居龙钢铁目前在国内先后与多家商用车专用车制造集团合作，全力为中国高端装备制造业服务。
