Abstract

A revolving die cutting mechanism, which is comprised of pedestal, slide track, slide carriage, die cutter holder on the slide carriage, die cutter and power push rod. In detail, the power push rod is glidingly inserted into the die cutting oil cylinder, which is fastened together with pedestal. End of die cutter is connected with die cutter fixed shaft. The shaft can be reelingly deployed into the die cutter holder. In addition, the fixed shaft is coaxially configured with gear, which joggles with the racks that are set in the rack holder and can move vertically towards the die cutter rotating axis. During die cutting, the die cutter moves for cutting and reelingly lacerates edges of workpiece at the same time, thus ensuring neat surface of processed workpiece, avoiding leveling workpiece surface and boosting up working efficiency and product quality.

Description

The rotation punching mechanism

Technical field

The utility model relates to a kind of workpiece punching mechanism, is applicable to hole punching on workpiece.

Background technology

Existing workpiece punching mechanism, generally comprise: pedestal, be arranged on the described pedestal and the slide rail that extends along the horizontal plane direction, be slidingly arranged in slide on the described slide rail, regularly be arranged on stamping knife holder on the described slide, be arranged on stamping knife, power push-rod on the described stamping knife holder, an end of described power push-rod is inserted in the die-cut oil cylinder that is fixed in the pedestal outside slidably.When workpiece is carried out stamping-out, be fixedly connected on that power push-rod on the described slide drives described slide and the stamping knife holder moves to the workpiece direction, the stamping knife that is arranged in the stamping knife holder begins die-cut workpiece, the material of the surface of the work that stamping knife contacted is subjected to the cutting force of stamping knife and comes off at this moment, and the material around the workpiece that stamping knife contacted caves in because of receiving bending stress, so cause the outer surface injustice of the workpiece processed, need before next process carries out, carry out planarizing process by the outer surface to workpiece, therefore reduce the working (machining) efficiency of workpiece.

Summary of the invention

The utility model purpose provides a kind of rotation punching mechanism, can make the die cut surface of processed workpiece smooth, reduces this step of the outer surface of workpiece being carried out planarizing process, improves the working (machining) efficiency of workpiece.

The technical solution of the utility model is: a kind of rotation punching mechanism, comprise pedestal, the slide rail that is arranged on the described pedestal and extends along the horizontal plane direction, be slidingly arranged in the slide on the described slide rail, be arranged on the stamping knife holder on the described slide regularly, be arranged on the stamping knife on the described stamping knife holder, power push-rod, one end of described power push-rod is inserted in the die-cut oil cylinder slidably, described die-cut oil cylinder and described pedestal are provided with permanently, the end of described stamping knife is fixedly connected with the stamping knife fixed axis, described stamping knife fixed axis is arranged in the stamping knife holder rotationally, the coaxial gear that is set with on the described stamping knife fixed axis, described gear is meshed with the tooth bar that can move along the direction perpendicular to the rotating shaft of stamping knife that is arranged in the tooth bar holder.

Described stamping knife is a cylindrical work piece, and the top of described stamping knife is provided with at least one tip.

One side of described tooth bar holder is connected with the rotary oil cylinder that fixes setting with pedestal, is provided with piston in the described rotary oil cylinder slidably, and an end of described piston is fixedly connected on an end of described tooth bar.

The utility model compared with prior art has following advantage: described stamping knife advance die-cut in the rotation, make the tip of stamping knife scratch the outer surface of workpiece earlier, so the suffered bending stress of the material around the workpiece that contacted of stamping knife is less, and be unlikely to cave in, thereby the die cut surface of the workpiece that the utility model processed is smooth, reduce this step of the outer surface of workpiece being carried out planarizing process, improved operating efficiency and product quality.
