Description

Automatic feeding and discharging manipulator of punch press TECHNICAL FIELD

[0001] The present application belongs to the technical field of manipulators, in particular relates to an automatic feeding and discharging manipulator of punch press. BACKGROUND

[0002] The punch press is a kind of mechanical equipment used for processing metal materials, which is usually used for punching, shearing, forming, punching and other operations on metal plates or other metal workpieces according to specific design requirements. The punch press mainly applies pressure to the workpiece through a punch, thereby forming the required hole or shape on the metal. The working principle of the punch press is to drive the mechanical transmission system by the motor to make the punch reciprocate vertically, and the workpiece is impacted by this movement. The size and capacity of the punch press can be different according to the needs, from small single punch press manually operated to large automatic numerical control punch press.

[0003] However, the prior art still has great deficiencies, such as:

[0004] In the prior art, during the use of the punch press, most of the time, the manipulator will take the workpiece to be processed from the conveying belt or storage area according to the program, accurately place it in the processing position of the punch press, and after processing, the processed workpiece will be taken away. At present, when the manipulator takes and places the workpiece, most of the time, a suction cup is used to adsorb the workpiece. However, in order to ensure that the workpiece does not fall off during movement, multiple suction cups are usually used to adsorb the workpiece. However, due to the fixed position of the multiple suction cups, the position cannot be adjusted according to the size, weight and shape of the workpiece, resulting in poor effect during use.
