Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, and in particular to a steel plate conveying roller mechanism. Background Art

[0002] At present, the hot forming line mainly heats the steel plate at high temperature before hot forming. After heating, it is transported out of the furnace mouth, placed on the mold, and then transported out after being formed by the press. The heating temperature of the steel plate reaches 900℃ or above. Manual transportation has the problems of high workload and low work efficiency for workers, and workers are easily tired during the operation, resulting in unstable working state and increased work danger. In addition, the heat radiation of high-temperature steel plates is also very dangerous to the human body. It is very easy to cause damage to the workpiece and the staff during the material handling process. With the development of automation, robots have emerged. Therefore, robots can be used instead of manual labor to transport steel plates. After the steel plates come out of the furnace mouth, corresponding conveying mechanisms are required to cooperate with the robots to realize the transportation. Summary of the invention
