Metal punching die

Abstract

The invention belongs to the technical field of dies, and particularly relates to a metal punching die. The metal punching die comprises a bottom plate, a lower die, an upper die, guide sleeves, connecting strips, a mounting plate, a first mounting hole, second mounting holes, a fixing sleeve, an electromagnet, a guide ring, a push block, a movable iron rod, a first spring, a material guide pipe,a second spring, a connecting pipe, a three-way pipe, a dust suction box, a side plate, a first rubber ring, a first filter screen, a handle, a circular ring, a discharge hole, guide rods, a punchingcavity, metal blocks, third springs, a pressing plate, a punching rod, a mounting frame, a centrifugal impeller, a motor, a baffle ring, a frame, a second rubber ring, a second filter screen and gas springs. The metal block punching device is reasonable in structure and suitable for punching and removing excess material on one side of the metal block; and during punching, the punching rod is in contact with the metal block, and the pressing plate and the multiple third springs are arranged, so that the pressing limit of the metal block can be carried out in advance, the stability of the metalblock during punching is improved, movement and upwarping are avoided, and the punching precision is improved.

Description

technical field [0001] The invention belongs to the technical field of dies, in particular to a metal stamping die. Background technique [0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts; during processing, part of the remaining material can be punched, or change its shape. [0003] When flushing out the remaining material of the metal workpiece, it may be necessary to use a stamping die for processing; some stamping dies carry the workpiece through the cavity, and there may be a gap between the workpiece and the cavity. When processing one side of the workpiece, and The workpiece may be irregular. When one side is under pressure, it may warp or move, which may affect the stability or accuracy of processing; after processing, manual cleaning and collection of residual materials and workpiece cleaning may be requi...
