Description

Technical Field

[0001] The invention relates to the technical field of plate forming, and in particular to an arc-shaped plate forming machine. Background Art

[0002] Plates are flat rectangular building material boards of standard size, used in the construction industry to make wall, ceiling or floor components. They also refer to metal plates that are forged, rolled or cast. At present, some wood plates or composite plates, when used, sometimes need to be bent into arcs by a plate rolling machine due to the usage scenarios and usage effect requirements.

[0003] In the prior art, a plate rolling machine is used to perform arc forming processing on a plate to meet different usage requirements and usage occasions. However, when a plate rolling machine in the prior art performs arc forming processing on a plate, it can only process a plate with good ductility. However, for plates that are not easy to bend, such as melamine plates and PE plates, arc processing is very difficult, and it is impossible to ensure uniform force during the bending process, resulting in poor bending effect, and even quality problems, which cannot meet the construction needs.
