One-time dual-hole inward turning device

The invention relates to a one-time dual-hole inward turning device. A mold locking mechanism comprises a left locked mold. A left locked mold inclined plane is machined on the left side inside the left locked mold. A left inner mold is machined on the other side inside the left locked mold. A left locked mold spring base for fixing a spring is machined at the lower portion of the left inner mold. A left locked mold sliding strip is machined in the middle of the left locked mold. A left locked mold right sliding block and a left locked mold left sliding block are machined on the two sides of the lower portion of the left locked mold. A spring base is machined on the inner side of the left locked mold right sliding block. A lower mold spring is installed on the spring base. The one-time dual-hole inward turning device has the beneficial effects that mold locking is convenient due to the combined movement of the left locked mold and the right locked mold; mold stripping is easy, and the working efficiency is greatly improved; due to the fact that a stamping straight wedge block and a stamping flat wedge block are symmetrically installed, one-time dual-hole inward turning can be completed through one-time stamping; the concentricity obtained after dual-hole inward turning is ensured; and multiple positions of the device are reset through the spring, and the automation degree of the device is high.
