S1, the card hole (31) of absorbable-bone plate ontology (3) is directed at axis (211), and absorbable-bone plate ontology (3) level is put It sets on bone plate stationary fixture (2)；
S2, enable specified actuator (4) that connecting shaft (22) is driven to move up, thus what drive was correspondingly connected with connecting shaft (22) Two fixture joint units (21) form certain angle, and angle measuring sensor (8) detects two fixture joint units (21) Angle, and when angle reaches specified angle, actuator (4) stop motion；
The corresponding infrared heating device starting of S3, the connecting shaft moved up (22), with the profiling for absorbable-bone plate ontology (3) Deformation position provides heat, and maintains the temperature at 80-160 degrees Celsius, and heating time is -60 minutes 30 minutes；
S4, after infrared heating device heating specified time, enable motor (113) that cooling blower (6) is driven to be moved to deformation position Surface simultaneously provides 25-50 degrees Celsius of low temperature environment, and the low temperature time continues -40 minutes 20 minutes.
