[0002] In the field of elevator chain production, due to the different conveying materials and capacities, the chain also has many structural shapes. For large-sized chains, in order to increase the stability of fastening, the six-hole plate is often made into a bent form to improve the rigidity and bearing capacity of the chain plate. This shape of chain plate can be achieved through casting, die forging, hot bending deformation and other methods. Therefore, the use of hot bending deformation in small batch production can save costs, but during the production process, the operator needs to move back and forth constantly to load the workpiece into the heating furnace one by one, and then take the workpiece out of the heating furnace one by one, which is labor-intensive. At the same time, the heating of the workpiece can only be judged by the experience of the operator whether it is heated to the approximate bending temperature for bending. If the estimate is insufficient, the workpiece will melt due to excessive heat or crack due to insufficient heat, resulting in a large amount of scrap. Summary of the invention
