This application relates to a stamping die and a stamping method. A first and second unloading member are spaced apart along the y-axis and form a processing groove for placing a sheet to be processed. A second preforming component, a second shaping component, and a second unloading member are movable with a limiting component along the x-axis. The first or second preforming component is movably inserted into the processing groove along the y-axis. The first shaping component is pressed against at least a portion of the preforming section along the y-axis, and the at least a portion of the preforming section is sandwiched between the first shaping component and the second unloading member. Alternatively, the second shaping component is pressed against at least a portion of the preforming section along the y-axis, and the at least a portion of the preforming section is sandwiched between the second shaping component and the first unloading member. The stamping die and stamping method provided by this application solve the problem that during the processing of a heat sink, the stamped portion is prone to twisting, deformation, or even rolling.
