Sliding block two-stage drawing die structure

The utility model relates to a slide block two-stage drawing die structure. When products with variable pipe diameters in pipes are machined at present, a traditional arc sliding block structure cannot be smoothly executed due to interference of a mold structure, and the quality of finished products is affected. The bottom sliding block comprises a bent pin and a fixed seat, and is characterized in that the bent pin is connected with the bottom sliding block and drives the bottom sliding block to slide, the bottom sliding block is connected with an arc sliding block, the outer end of the arc sliding block is connected with an arc sliding block head insert, and the arc sliding block head insert is opposite to a to-be-machined product. A connecting seat is arranged on the arc-shaped slidingblock, a connecting rod is arranged on the connecting seat, and the connecting rod is connected with the arc-shaped sliding block. A sliding block two-stage drawing structure is adopted, the bottom lower sliding block is driv
