Stamping equipment for guard plate of computer case

Abstract

The invention discloses stamping equipment for a guard plate of a computer case. The stamping equipment realizes simultaneous stamping machining of a plurality of blank plates at one time, adopts a manipulator for automatic transferring, and improves the efficiency of blank transferring and stamping. According to the stamping equipment, anti-backlash-dislocation mechanisms are arranged, when the blank plates located on the lower layer and forming dies located on the lower layer generate backlash acting force on forming dies and the blank plates above the same to enable the blank plates to be dislocated at the moment when a stamping hydraulic cylinder stamps the plurality of blank plates simultaneously, the anti-backlash-dislocation mechanisms can prevent adverse effects generated when theplurality of blank plates are stamped simultaneously effectively, each anti-backlash-dislocation mechanism comprises an anti-backlash driver and a detection and triggering mechanism, and the detectionand triggering mechanisms are arranged so that the driving action time of the anti-backlash drivers can be located at the moment after the action of the stamping hydraulic cylinder to prevent the influence of the backlash effect of the backlash force on the stamping hydraulic cylinder from causing the influence of dislocation between the forming dies and the blank plates.

Description

technical field [0001] The invention specifically relates to a stamping equipment for a computer case guard plate, belonging to the technical field of stamping equipment. Background technique [0002] For the protective plate of the computer case, since it is a sheet metal part, when it is formed, it is generally formed by stamping. The current stamping equipment generally uses stamping dies and stamping hydraulic cylinders for stamping and forming. Although this stamping and forming method is simple, it generally requires manual loading during stamping, and each stamping can only realize the stamping of one workpiece. This results in lower punching efficiency, and if a plurality of stamping dies are simply stacked up and down together, when stamping, due to the stamping hydraulic cylinder pressing down, due to the setting of the multi-layer stamping die and the blank, the stamping die will After pressing, the stamping die in the lower part will produce a large recoil force...

Problems solved by technology

The current stamping equipment generally uses stamping dies and stamping hydraulic cylinders for stamping and forming. Although this stamping and forming method is simple, it generally requires manual loading during stamping, and each stamping can only realize the stamping of one workpiece. This results in lower punching efficiency, and if a plurality of stamping dies are simply stacked up and down together, when stamping, due to the stamping hydraulic cylinder pressing down, due to the setting of the multi-layer stamping die and the blank, the stamping die will After pressing, the stamping die in the lower part will produce a large recoil force on the stamping die in the upper part. The superposition of the recoil force in multiple layers will cause the stamping hydraulic cylinder to move downward to the maximum stroke and there will be a large recoil retraction. , this recoil retraction stroke will cause a dislocation between the stamping die and the blank. This dislocation will deform and twist the formed workpiece under the continuous relative displacement of the lower stamping die, affecting the quality and effect of the workpiece forming
