Stamping die for axle tube parts

Abstract

The invention belongs to the field of part machining, and particularly discloses a stamping die for axle tube parts. The stamping die for the axle tube parts comprises a rack, a lower die base is fixed to the rack, an upper die base located above the lower die base is vertically connected to the rack in a sliding mode, clamping plates are transversely connected to the positions, located on the twosides of the upper end of the lower die base, of the rack in a sliding mode, gaps are formed between the lower ends of the clamping plates and the upper end of the lower die base, bristles are fixedto the lower ends of the clamping plates, and the lower ends of the bristles abut against the upper end of the lower die base; cavities are formed in the clamping plates, air outlet holes communicating with the cavities are formed in the lower ends of the clamping plates, air outlet one-way valves are mounted in the air outlet holes, air suction holes are formed in the opposite faces of the two clamping plates, the opposite sides of the air suction holes in the two clamping plates incline downwards, air suction one-way valves are mounted in the air suction holes, and through holes communicating with the cavities are formed in the upper ends of the clamping plates; and the upper ends of the clamping plates are detachably connected with blocking covers for blocking the through holes. By theadoption of the scheme, the problems that punching is affected by chippings on the lower die base, and the parts are prone to toppling over during die retreating can be solved.

Description

technical field [0001] The invention belongs to the field of parts processing, and in particular relates to a stamping processing die for shaft tube parts. Background technique [0002] In industrial products, shaft parts are suitable for maintenance operations of one or more CNC machine parts. Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and Bearing load, according to the different structural forms of shaft parts, it can be divided into solid shafts and hollow shafts (ie pipes). [0003] When the shaft parts are punched by the punching machine, such as when the rocker shaft is headed, the parts will be stuck in the upper or lower die of the punching machine, and the ejector rod is often used to eject the shaft parts when ejecting the mold. , when the shaft parts are ejected, in order to avoid the parts from being dumped and damaged, the operator needs to hold the part...
