Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and in particular to a punching device capable of realizing upper and lower synchronous punching. Background Art

[0002] At present, with the increasingly fierce competition in the manufacturing industry, the requirements for the stamping accuracy and quality of workpieces by stamping machines are getting higher and higher. However, in the existing technology, some stamping machines can only stamp the workpiece through the mold on the upper slider, and cannot stamp the upper and lower sides of the workpiece through the upper mold and the lower mold respectively. Although some stamping machines can stamp the upper and lower sides of the workpiece through the upper mold and the lower mold, the upper mold and the lower mold are not synchronously linked to stamp the workpiece, resulting in poor processing quality of the workpiece, and even the phenomenon of scrapping the workpiece, which increases the loss of the enterprise.
