Abstract

An improved forged wheel trimming die, including a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod. The improved forged wheel trimming die has the advantages that by adding two follow-up retainer plates to the stripper plate of the die, burrs of a forged wheel blank are constrained along the radial direction during the cutting, thereby avoiding breakage due to excessive deformation; in this way, the burrs can be protected from damage and knocked out successfully by the knockout rod after being cut off from the blank.

First claim

The invention claimed is:

1. An improved forged wheel trimming die, comprising:
a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod, wherein the lower die base lower plate is fixed on the bottom plate by bolted connection, the stripper guide pillar and the lower die base stiffened plate are fixed on the lower die base lower plate by bolted connection, the connecting rod is fixed on the knockout rod by bolted connection, the lower die base upper plate is fixed on the lower die base stiffened plate by bolted connection, the stripper plate is fixed on the connecting rod by bolted connection, the lower die is mounted on the lower die base upper plate by bolted connection, the follow-up retainer plates are fixed on the stripper plate by means of welding, the shearing blade is mounted on an upper die by bolted connection, and the ejector block is fixed below the knockout rod by bolted connection.

2. The improved forged wheel trimming die according to claim 1 , wherein the number of the follow-up retainer plates is two, and the two follow-up retainer plates symmetrically positioned on both sides of the improved forged wheel trimming die.
