The invention relates to the technical field of
metal processing and manufacturing, and discloses a precision
stamping and
forging integration method which comprises the following steps: step 1, establishing a workpiece three-dimensional parameterized model, and predicting
material flow stress distribution; 2, a
servo motor is adopted to drive a
punching machine, and the temperature of a die is kept at 80 + / -5 DEG C in the
punching process; thirdly, the workpiece is placed in the environment with the vacuum degree smaller than or equal to 1 * 10 Pa; step 4, adopting a gradient cooling process, firstly keeping in a
nitrate bath at 180-220 DEG C for 5-8 minutes, and then cooling to
room temperature at the rate of 30-50 DEG C / s; and fifthly, the
surface roughness Ra is smaller than or equal to 0.6
micrometer through micro shot blasting treatment. Through the synergistic effect of three-
dimensional modeling and a dynamic compensation mechanism, in combination with
laser online detection and high positioning precision of a feeding mechanism,
dynamic control over a die gap, real-time monitoring of the workpiece size and accurate prediction of
material flow stress distribution are achieved, the problems of tearing belts and size fluctuation of traditional
stamping parts are solved, and the production efficiency is improved. And the product
assembly precision and batch consistency are ensured.
