Stainless Steel Disc Springs

Since the development of coil springs in turret tooling, engineers have been challenged to increase the productivity of turret presses even further. In a traditional press, the option of material type and material thickness is limited by the coil springs inability to produce a high force in a short linear distance. When this performance is necessary, coil springs will have a negative effect on the quality of the formed product and efficiency of the manufacturing process. SPIROL® Disc Springs are the solution to form thick materials, large extrusions, and more complex designs. When stacked in series, they are capable of providing a greater, more consistent stripping force than coil springs and require less space. They have become an instrumental component in the advancement of turret punch press tooling. Visit www.SPIROL.com to learn more!

The mechanical back-up design uses SPIROL® Disc Springs. Under normal circumstances, the hydraulic system holds a constant pressure on Disc Springs stacked in series. If pressure fails to be maintained, the stack of Disc Springs decompresses to actuate the braking mechanism. A compression spring or wave spring is not capable of providing the force required (in the space available) to actuate the brakes. The reliability of this safety system is dependent on the consistent performance of Disc Springs. In this critical application, the Disc Spring’s performance and level of predictability improves product quality and ensures overall safety. SPIROL® Disc Springs have a high capacity to consistently store releasable mechanical energy. Visit www.SPRIOL.com to learn more!

DEWALT’s lead design engineer for drills was tasked with designing a high power right angle drill that is lightweight, compact, and portable. The goal with the design was to maximize performance while minimizing the size of the tool. The design would incorporate a mechanical clutch built to limit maximum torque output to 70 ft-lbs. Absent the clutch, with the huge gear reduction of 75:1, the drill would be capable of producing a lock rotor torque at the spindle of 175 ft-lbs, transmitted directly to the operator of the tool. It was determined early on that the clutching thrust required in the space available could only be achieved by a Disc Spring design. Compared to conventional coil springs, Disc Springs offer a higher load capacity in less space. Additionally, longevity and reliability is a high measure of quality for professional tools used on a daily basis. The life and performance warranty of the tool was reliant on the Disc Spring design.

SPIROL offers Disc Springs pre-stacked in custom configurations (greased or ungreased) packaged in shrink wrap with a perforated tab for ease of insertion into the assembly. The Pre-Stacked Disc Springs are delivered intact which saves time, mistake-proofs the assembly process, and eliminates the mess associated with greasing the stack.
