Multi-station precise full-automatic punching device

Abstract

The invention relates to a multi-station precise full-automatic punching device, comprising a bottom plate, wherein a vertical rod is fixed to the top of the bottom plate, a placement plate is fixed to the top of the vertical rod, a butt joint column is fixed to the top of the placement plate, a punching groove is formed in the center of the top of the butt joint column, a plurality of U-shaped grooves are formed in the top of the butt joint column, two moving blocks are connected into the U-shaped grooves in a sliding mode, second supporting rods are fixed to the tops of the moving blocks, ejector blocks are fixed to the tops of the second supporting rods, a second spring is fixed between the two moving blocks, two positioning rings are fixed in the U-shaped groove, the position of the positioning ring close to one side of the punching groove is higher than the position of the other positioning ring, and the two positioning rings are connected with the corresponding second supporting rods in a sleeving mode. According to the punching device, the ejector blocks on the outer side are used for firstly making contact with a workpiece to support the workpiece, then the second springs are extruded, the ejector blocks on the inner side are jacked up, the position nearby a punched hole is supported, and therefore the situation that the workpiece deforms due to the fact that the bottom is suspended in the air during punching is avoided.

Description

technical field [0001] The invention relates to the technical field of stamping processing, in particular to a multi-station precision full-automatic stamping device. 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. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity. [0003] When the traditional stamping device is working, the worker needs to reach out to put the workpiece on the stamping die. At the same time, after the stamping is completed, the workpiece needs to be removed manually. Not only is the process cumbersome, but there are als...
