Novel punching machine

Abstract

The invention relates to a novel punching machine. The novel punching machine comprises a rack, a driving device, a crank shaft, a first crank shaft connection rod, a second crank shaft connection rod, a first horizontal guide block, a second horizontal guide block, a first adapter coupling connection rod, a second adapter coupling connection rod, a first vertical guide connection rod, a second vertical guide connection rod, a first lever, a second lever, a first mold adjusting connection plate, a second mold adjusting connection plate, a first slide block connection rod, a second slide block connection rod, a slide block and a worktable, wherein the driving device is in driving connection with the crank shaft; the crank shaft is in drive connection with the first crank shaft connection rod, and the second crank shaft connection rod respectively; and the slide block is located above the worktable. The novel punching machine provided by the invention has the advantages of simple structure, small inertia and high precision; the staying time of a bottom dead center is long, a punching surface of a punched workpiece is smooth and the quality of the punched workpiece is improved; and a stressed reversed impact force is small, abrasion to equipment is small and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a novel punching machine. Background technique [0002] A punch press is a device used to stamp sheets. Existing punch presses include the following three categories: 1. crankshaft punch presses; 2. toggle punch presses; 3. multi-link punch presses. [0003] The crankshaft punch is easy to manufacture and low in cost. During the high-speed stamping process, the stamping die has a large inertia, the depth of stamping will change with the speed, and the precision is not easy to control. The time from the time of the workpiece to the stamping of the die to the set depth of the workpiece or the time from the point where the stamping force occurs to the end point of stamping) is short, resulting in poor metal fluidity of the workpiece to be processed, and it is easy to make the stamping surface rough. The quality of the stamping parts in the stamping process is poor. Th...
