The invention relates to the technical field of bamboo cylinder 
processing, in particular to a vertical bamboo board cylinder forming 
machine. The vertical bamboo board cylinder forming 
machine comprises a rack, a lifting adjusting mechanism, a supporting mechanism, a first forming 
assembly, a second forming 
assembly, a third forming 
assembly and a fourth forming assembly, wherein the lifting adjusting mechanism, the supporting mechanism, the first forming assembly, the second forming assembly, the third forming assembly and the fourth forming assembly are arranged on the rack respectively; the lifting adjusting mechanism comprises a lifting frame, a lifting oil cylinder and a heating die head; the supporting mechanism comprises a first mounting frame, a first heating roller, a second mounting frame and a second heating roller; the first forming assembly comprises a first oil cylinder and a first 
hot pressing plate; the second forming assembly comprises a second oil cylinder and a second 
hot pressing plate; the third forming assembly comprises a third oil cylinder and a third 
hot pressing plate; and the fourth forming assembly comprises a fourth oil cylinder and a fourth hot pressing plate. According to the vertical bamboo board cylinder forming 
machine, 
cracking of a bamboo board in the cylinder forming process and a formed bamboo cylinder is avoided, the 
mechanical property of the bamboo cylinder is improved, and the 
processing efficiency is improved while the fitting property of the bamboo board and a core die is improved.
