[CN 201610984930.4] Thermal Roll Forming Device for Variable Section Thickness Thin Plate of Vertical Hydraulic Press
[CN 201610984930.4] Title of Variable Section Thickness Sheet Hot Roll Forming Device for Vertical Hydraulic Press: Application Number of Variable Section Thickness Sheet Hot Roll Forming Device for Vertical Hydraulic Press: CN 201610984930.4 Applicant: North University of China Application Date: 2016-11-3 Patent Type: Invention Application for Variable Section Thickness Sheet Hot Roll Forming Device for Vertical Hydraulic Press, This invention relates to the technical field of machinery; The upper end of the rack is clamped in a fixed plate, and a backing plate is provided between the fixed plate and the upper template, and the three are connected and fixed through a first screw, the rack meshes with the gear, and the gear is connected and fixed with both ends of the roller shaft through a key; The left and right ends of the roller shaft are inserted into the support plate, and an eccentric copper sleeve is arranged between the two, and a flange ring is arranged around the eccentric copper sleeve. The side wall of the support plate is connected with a guide sleeve through a second screw. The rack is arranged in the guide sleeve; the outer wall of the roller shaft is provided with a groove, which plays the role of automatic positioning of the blank, which is convenient for the whole rolling process to be carried out quickly. Solve the problems of producing thin plate parts with vertical extrusion machine, and improve the comprehensive mechanical properties of the parts, especially the strength in the rolling direction has been significantly improved, and effectively solve the problem of insufficient strength of machine parts.
