Straight Side Double Crank Presses

Superior Stability for Progressive Tooling: When running wide progressive dies or transfer line operations, maintaining perfectly parallel ram descent is critical. Used straight side double crank presses, frequently referred to as 2-point presses, utilize dual pitman connections to suspend the slide. This two-point architecture drastically reduces ram tipping and cocking when tooling applies off-center loads across a wide bed.

The Mechanics of Double Crank and 2-Point Stamping Presses

Managing Off-Center Loads

In modern stamping, a multi-station progressive die rarely distributes tonnage perfectly in the center of the bed. A heavy drawing station on the left side of the tool creates an off-center load. If a single point press were used, the ram would tip, causing the punches to enter the die matrix at an angle, leading to catastrophic tool failure. A 2-point stamping press utilizes a crankshaft or eccentric gear setup that drives two separate pitmans. This dual suspension forcibly maintains ram parallelism from left to right, safely absorbing unbalanced tonnage.

Ideal Applications for 2-Point Mechanical Presses

Investing in a used double crank press is the standard procedure for facilities focused on:

  • Progressive Die Stamping: Feeding coil stock through multiple stations for blanking, piercing, and forming.
  • Large Panel Fabrication: Producing wide, relatively shallow parts like appliance doors or automotive body skins.
  • Transfer Press Automation: Utilizing automated transfer rails to move parts across a wide bolster plate.

Integration Insight: When pairing a used straight side double crank press with a servo roll feeder, pay close attention to the press's "windows" (the openings between the side columns). Larger side windows allow for easy integration of automated coil feeding equipment and efficient scrap removal.
