Prior art is compared, the present invention adopts patrix to comprise upper shuttering, be embedded at the pressing block bottom upper shuttering, can change in time when pressing block to be crossed and to affect cold forging effect for a long time service time, the counterdie cavity placing processing parts is provided with in counterdie, the logical rod that processing parts can be ejected from counterdie cavity is vertically provided with in described counterdie cavity, described logical rod can slide up and down to the bottom of extending counterdie through the through hole of counterdie, the outside counterdie of counterdie cavity is provided with the neck edger of processing parts, after processing parts puts into counterdie cavity, patrix moves down and extrusion process part top under drive unit drives, processing parts is moved down and enters counterdie cavity, conical neck is by the colored tooth part cutting into setting flower tooth of neck edger, the advantage of this structure is, processing parts is cut by neck edger at patrix effect inferior pyramidal neck, the one-shot forming of flower tooth, speed is fast, effective, the lower end of processing parts is inconsistent with logical rod, avoid the horizontal displacement of processing parts, process more steady, after completing cut-flower tooth, move back mould also more convenient.
Summary of the invention
Technical problem to be solved by this invention provides for above-mentioned prior art present situation that a kind of structure is simple firm, cold-heading process steady, the non-damageable part neck cold-heading cut-flower stamping die causing type for part pressure of mould.
The present invention solves the problems of the technologies described above adopted technical scheme: this part neck cold-heading cut-flower stamping die, comprise upper die and lower die, described patrix can be moved up and down relative to counterdie by drive unit, it is characterized in that: described patrix comprises upper shuttering, be embedded at the pressing block bottom upper shuttering, the counterdie cavity placing processing parts is provided with in described counterdie, the logical rod that processing parts can be ejected from counterdie cavity is vertically provided with in described counterdie cavity, described logical rod can slide up and down to the bottom of extending counterdie through the through hole of counterdie, the outside counterdie of counterdie cavity is provided with the neck edger of processing parts, after processing parts puts into counterdie cavity, patrix moves down and extrusion process part top under drive unit drives, processing parts is moved down and enters counterdie cavity, conical neck is by the colored tooth part cutting into setting flower tooth of neck edger.
As improvement, described counterdie includes die sleeve shell, internal mold, described internal mold is placed in die sleeve shell, the middle top surface of described internal mold is convexly equipped with protuberance, described neck edger is placed on the periphery of protuberance closely, and described counterdie cavity is positioned at protuberance, and the gear cutter of the setting flower tooth of described neck edger is positioned at counterdie cavity top, described neck edger and die sleeve shell fix, and described logical rod extends the bottom of counterdie from the through hole of internal mold.
Further improvement, described neck edger neighboring is provided with the reinforcing ring that can improve neck edger location stability and strengthen neck edger intensity, and circumferential lateral surface and the die sleeve shell of described reinforcing ring fix.
As improvement, the bottom surface of described pressing block is mutually concordant with the bottom surface of upper shuttering.
As improvement, the gap between described logical rod and counterdie through hole is 0.02 ~ 0.03mm.
As improvement, the bottom of described logical rod is provided with the boss entering counterdie through hole bottom the anti-stop-pass rod of energy.
