Abstract. Research has been carried out on the process of plastic folding of bar stocks with round and barrel-shaped cross-sections. The dependence of the movement of the movable tool on the bending angle has been established. The force parameters of the deformation process and the stress-strain state in the bending workpiece are determined based on the results of finite element modeling of plastic bending.

“…Yang Lianhong [8] analyzed the mechanism underlying bonding behavior during hot rolling, discussed the hot rolling process conditions affecting the bonding behavior, and proposed the mechanism of bonding nucleation and growth. S I Platov et al [9] studied the operation of the roll system when a liquid lubricating material was applied during the hot rolling process, and demonstrated that the lubricating material reduced the wear of the work roller by 10-12%, effectively reducing the sticking phenomenon. Zhang Chi et al [10] discussed the behavior of sticking hot rolling deformation rollers, and suggested that sticking rollers occur due to a process of nucleation, growth, and saturation, and that micro-cracks are needed to provide the necessary nucleation position for adhesion of the roller surface.…”

In the process of copper alloy hot continuous rolling, the problem of copper sticking to the roller seriously affects the surface quality, performance, and service life of the copper products. Roll sticking occurs as the adhesion energy of Cu is lower than that of Fe and the Fe-Cu interface, and the severe surface deformation which forces the copper into direct contact with the roll during the process of profile rolling. Based on the copper deformation law and adhesion phenomenon in the hot continuous rolling process, a rolling deformation model and roll copper adhesion model or copper alloy hot continuous rolling were established, and their simulation was realized using finite element software. Through finite element modeling of the hot rolling deformation zone, the distribution of the temperature, contact normal stress, and exposure rate in the hot rolling deformation zone were obtained, which were consistent with the actual roll adhesion phenomenon and copper adhesion position. To address the copper sticking behavior of the rolls, the process optimization method of matching the motor speed with the elongation coefficient (the 1# and 2# motor speeds were adjusted to 1549 r/min and 1586 r/min, respectively), adjusting the roll gap to 7.9 mm, and increasing the number and pressure of roll spray nozzles were put forward, which effectively solved the problem of copper sticking to the roll, significantly improved the surface quality of the copper and the service life of the roll, and can be used in production.
