A four-slide is a metalworking Machine Tool used in the high-volume manufacture of small stamped components from bar or wire stock. The press is most simply described as a horizontal stamping press that uses cams to control tools. The machine is used for progressive or transfer stamping operations.
A four-slide is much different than most other presses. The key of the machine is its moving slides that have tools attached, which strike the workpiece to form it. These slides are driven by four shafts that outline the machine. The shafts are connected by bevel gears so that one shaft is driven by an electric motor, and then that shaft’s motion drives the other three shafts. Each shaft then has cams which drive the slides, usually of a split-type. This shafting arrangement allows the workpiece to be worked for four sides, which makes this machine extremely versatile. A hole near the center of the machine is provided to expel the completed workpiece.
Items that are commonly produced on this machine include: automotive stampings, hinges, links, clips, and razor blades.
