Description

TECHNICAL FIELD

[0001] The utility model relates to punch processing technical field, concretely is a punch. BACKGROUND

[0002] Punching refers to punching various patterns on materials such as steel plates, leather, cloth and wood boards to meet different needs, and the parts formed by the hydraulic forming process have advantages such as material saving, cost reduction and good performance, and with the extensive use of hydraulic forming parts, the processing method of holes on the parts has attracted more and more attention from domestic and foreign scholars. Since the tubular hydraulic forming part is hollow, it cannot be punched by traditional processing methods, and is generally processed by laser cutting method, which can ensure good processing quality, but the equipment investment is expensive and is not conducive to cost reduction. Hydraulic punching, as a new type of blanking method, punches hollow parts and parts with curved axes, and has advantages that cannot be matched by traditional processing technology. Hydraulic punching does not need a concave die in the entire punching process, which has great advantages in solving the processing of parts with too small internal dimensions or curved axes that cannot accommodate a concave die.

[0003] The punch is a die mainly used for punching various shaped holes on a plate or blank, and it is a kind of stamping die. Pressure is applied by a press to make the punch and the concave die work together to punch off the part of the plate that is not needed, thereby forming the required hole type. When the slide of the press moves downward, the upper die part also moves downward, the punch first contacts the plate, and as the pressure increases, the punch gradually cuts into the plate. Under the combined action of the punch and the concave die, the plate material is separated by the shearing force of the punch, forming a hole. When the slide of the press moves upward, the punch leaves the plate, and the unloading device unloads the plate from the punch, completing a punching operation.

[0004] The existing punch is used for punching by the cooperation of the punch and the concave die, but when the side surface of the product needs to be punched, the orientation of the product needs to be adjusted, which cannot be formed at one time, thereby reducing the processing efficiency.
