TECHNICAL FIELD

[0001] The present application relates to the technical field of punch machine tools, in particular to a protective self-feeding plate punching machine tool. BACKGROUND

[0002] In modern industrial production, punch machine tools, as an important processing equipment, are widely used in the processing and manufacturing process of metal plates. Traditional punch machine tools usually need manual feeding and discharging when stamping workpieces. This manual operation method has many problems, such as high labor intensity, low work efficiency, and is prone to safety accidents due to human error during operation. Especially when facing large quantities of plate processing tasks, the tediousness of manual feeding and discharging is more prominent, which seriously affects the production efficiency and processing quality.

[0003] In addition, the traditional punch machine tool lacks effective automatic protection devices during stamping. The operator needs to frequently enter and exit the stamping area when feeding and discharging, which not only increases the labor intensity of the operator, but also has high safety hazards. If the operator is careless during stamping, it may cause damage to the stamping die, and even endanger personal safety. Therefore, how to improve the automation level of the punch machine tool, realize automatic feeding and discharging function, and ensure the safety of the operation process is a problem to be solved in the current punch machine tool technical field.
