滚压机加工出来的材料为什么会出现皱纹

https://www.mhtcnc.com/product/rolling-bending-machine/公共铁路的修建，管道的铺设，锅炉、桥梁、船舶等的建设都离不开卷板机的保密工作，随着卷板机技术的发展，人们越来越多地使用卷板机，但是有时候我们会发现卷板机加工出来的材料会有一些皱褶，这是为什么呢？

Research on Mannhardt (Guangdong) CNC machine tools shows that excessive or slow advance speed of the bending machine during use can cause wrinkles in the processed products. During the operation of the bending machine, if the pushing speed is too high, it will cause excessive combustion of the steel pipe, resulting in wrinkles. When the propulsion speed is too fast, the arc causes the curved part to collapse internally, resulting in wrinkling of the internal arc. Uneven heating temperature between internal and external arcs can also lead to wrinkles in the processed material. When the internal arc temperature of the pipe exceeds the allowable range, material accumulation and wrinkles will occur on the inner side. To ensure that the processed material does not have wrinkles, attention should be paid to the use of the bending machine.
