The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass. 1. A device for processing columnar curved tempered glass , characterized by mainly comprising a glass heating furnace , a glass bending mechanism and a glass tempering mechanism connected sequentially , wherein the relative vertical position of each supporting roller of the glass supporting rollers in the glass bending mechanism is adjustable , and the supporting rollers are arranged in a curve corresponding to the shape of the glass to be formed so as to enable the supported glass to suffer bending deformation , and a conveying mechanism for outputting the formed curved glass in the axial direction of the supporting roller is arranged at the clearance of the rollers of the bending mechanism.2. The device according to claim 1 , wherein the conveying mechanism is constituted by rollers or a conveying belt.3. The device according to claim 1 , wherein the curved glass subjected to bending undergoes tempering treatment in a passing-through ...
