Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and examples.
[0025] In this embodiment, the nut stroke mold for high-speed nut forming machine used in the method and system for grinding the mold shell and the mold core together to form the taper of the mold surface is mainly suitable for 5-station and 6-station high-speed nut forming machines, and the range of nut specifications is The nuts produced by the cold heading process of M10~M24 in accordance with GB / T6170, GB / T6171, GB / T6172.1, GB / T6173, GB / T6174, GB / T56 and other national standards, due to the mold material and manufacturing process of this series The principles are the same and the parameters are similar. This embodiment mainly uses the M12 mold as an example for illustration.
[0026] In this example, if Figures 1 to 5 As shown, the nut stroke mold for a high-speed nut forming machine includes a stroke mold shell 1, an upper mold core 2, a lower mold ...
