the method comprises the following steps: placing a material on a lower grinding tool block (9), respectively starting a second driving cylinder (19) and a third driving cylinder (22), pushing a first clamping block (21) and a second clamping block (24) in opposite directions through the extension of a first telescopic column (20) and a second telescopic column (23), and clamping and fixing the material through a first clamping pad (25) and a second clamping pad (26);
step two: starting a first driving air cylinder (12) to enable a pressure head (13) to press down a first lifting column (14), enabling the first lifting column (14) to press down a second lifting column (15) through pressure to enable the second lifting column (15) to move downwards in an extending mode, and enabling an upper grinding tool block (17) to move downwards at a constant speed through further pressing down a third lifting column (16);
step three: stamping materials on the lower grinding tool block (9) through the upper grinding tool block (17) to manufacture a finished product, pulling up the first lifting column (14) through the pressure head (13), pulling up the second lifting column (15) through the first lifting column (14) through pulling force to enable the second lifting column (15) to contract upwards, and further pulling up the third lifting column (16) to enable the upper grinding tool block (17) to move upwards at a constant speed;
step four: the first clamping block (21) and the second clamping block (24) are pushed oppositely by the contraction of the first telescopic column (20) and the second telescopic column (23), the first clamping pad (25) and the second clamping pad (26) are separated from a finished product, by pressing the first pressing block (31) and the second pressing block (32) downwards and moving downwards through the contraction of the extension spring (36), the first positioning column (41) and the second positioning column (42), so that a concave area is formed between the product and the first and second adjusting blocks (28, 29), the finished product is stretched upwards through the concave area, so that the finished product is separated from the lower grinding tool block (9), the downward pressing of the first pressing block (31) and the second pressing block (32) is stopped, by the extension and the lifting of the extension spring (36), the first positioning column (41) and the second positioning column (42), so that the first pressing block (31) and the second pressing block (32) are restored to the original positions.
