Abstract

The invention relates to the technical field of punching of rigid workpieces, in particular to a punching machine. The punching machine comprises a supporting plate. A punching hole is formed in the supporting plate. The punching machine further comprises an ejector mechanism, punching mechanisms and an oil storage cylinder for storing hydraulic oil. The oil storage cylinder communicates with a first branch pipe and a second branch pipe located below the first branch pipe. The oil storage cylinder is internally and slidably connected with a transverse piston. The transverse piston is connected with a piston rod. The ejector mechanism comprises an ejector plate and a buffer bucket connected with the lower portion of the ejector plate. The number of the punching mechanisms is two. Each punching mechanism comprises a punching head, a connecting rod, a vertical piston and an oil separating pipe. The sizes of the punching heads of all the punching mechanisms are different. According to the technical scheme, the punching machine is characterized in that punching head replacing and punched part picking are very convenient, and the punching efficiency is improved advantageously.

Description

technical field

[0001] The invention relates to the technical field of punching of rigid workpieces, in particular to a punching machine. Background technique

[0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. During the stamping process, traditional stamping machines can only stamp one type and specification of stamping parts, which seriously wastes the efficiency of stamping equipment.

[0003] The Chinese patent with the notification number CN206229899U discloses a stamping mac...
