Automatic punching machine and stamping method

Abstract

The invention discloses an automatic punching machine. The automatic punching machine comprises a machine body, a lifting block, a stamping air cylinder, a stamping head, a workbench, a material moving mechanism and a discharging mechanism, wherein the material moving mechanism comprises a translation bottom plate and a material moving frame, the material moving frame is arranged on the translation bottom plate in a left-right horizontal moving mode, plate materials are fed through roller shaft sets, a discharging hopper can move left and right in a notch, a stamping base is fixedly installedon the translation bottom plate, the stamping head comprises a sleeve and a stamping body, wherein the sleeve and the stamping body are fixed on the lifting block, the upper part of the stamping bodyis connected with the sleeve through a buffer spring, a first electromagnet on the stamping body and a second electromagnet on the sleeve are attracted together when the stamping body moves upwards, stamping knives are mounted at the bottom of the stamping body along the peripheral wall of the stamping body, and a rectangular groove is formed in the center of the bottom of the stamping body. The automatic punching machine is compact in structure, can carry out automatic feeding and discharging on the plate materials and enables the plate materials to be stamped into annular rings, the use is quite convenient, the labor intensity of workers is greatly reduced, and the safety of the stamping operation is improved.

Description

Technical field [0001] The invention relates to the field of mechanical equipment, in particular to an automatic punching machine and a stamping method. Background technique [0002] Punch is a stamping press, mainly for sheet metal. In national production, the stamping process has the advantages of saving materials and energy, higher efficiency than traditional mechanical processing, low technical requirements for operators, and making products that cannot be achieved by mechanical processing through various mold applications. It has more and more uses. [0003] However, currently some smaller companies mostly use semi-automatic processing punches. However, during the processing, the operator needs to manually put the sheet to be punched under the punching head, and the annular ring formed by the punching needs to be removed manually, which is relatively labor intensive for workers who work for a long time and poses great safety risks. Summary of the invention [0004] The purpo...
