Whether to improve ergonomics, increase production or if an applications set-up requires it, we often receive requests for a hand press that can attain full stroke with less handle rotation, particularly with longer stroke presses. Listening to needs of our customer base, we recently developed a solution to accomplish just that, a device that is adaptable to most manual SCHMIDT presses.rnrnNo magic. We simply take advantage of a gear ratio to provide the same ram travel with less handle rotation. The standard unit has a 2 to 1 reduction ratio. The handle rotation now is half as compared to a standard press to achieve the same ram travel. If necessary, this ratio can be customized to fit a particular application. The down sides are; the press head becomes a bit wider, pulling the handle has become a bit harder (overcome the return spring) and the force output of the press is reduced byrnthe same ratio.rnrnHere is an example: Our standard Nr 3 Manual press requires 220 degrees of handle rotation to achieve its full 70 mm / 2.76” of ram travel. Maximum force is 2.4 kN / 540 lbs with a 200 N/ 44 lbs force in the handle. A press equipped with a 2:1 ratio handle rotation reduction will achieve the same 70 mm / 2.76” of total stroke with only 110 degrees of handle rotation. The generated force on the ram now is reduced to 1.2 kN / 270 lbs, based on the same 200 N/ 44 lbs input force on the handle.rnrnThis handle rotation reduction system can be added to any new Manual press and most existing Manual presses. Some minor modifications to the press head are required, so a press that is already in the field would need to be returned to Schmidt Technology for this upgrade.rn

Please note that the actuator itself cannot bernoffered as food grade compatible since this requires the actuator to be made outrnof stainless steel or be coated in a food grade compatible coating or platingrnwhich we don’t offer as a special option.rnrnPlease see the following documents regarding the technical specification and thernmaterial safety data sheet (MSDS).rnrnClick Here to download the PDF

rnOverhang Load Length Informationrnnnrn

nnThe overhang load length provides a reference for an appropriate offset of the load from the slider at which the actuator can operate smoothly without generating undesirable vibration.nnrnTake note that if the overhang load length is exceeded, vibration may increase the positioning time, generate longer overshooting, lower the positioning repeatability, etc.nnrnVibration can also cause the guide to get pinched or receive uneven loads and eventually fail prematurely. Accordingly, be sure to observe the allowable overhang load length. (The load coefficient will change.)nnrnBased on our experience, the overhang load length should not exceed approx. 5 based on the expression “L / l,” where L represents the overhang load length and l represents the slider length. If “L / l > 5,” use a double-guide specification or take other appropriate measures to ensure a sufficient span.nnrnnn(Supplemental information)nnrnWith a measuring system equipped with a camera, the overhang load length may take a value of approx. 3 to 4. On the other hand, you can slightly increase the value of “L/ l” in applications where you only want your actuator to operate as intended.nnrnnnnnrnnnTIPS-090150 – Issue date: 12/28/09nnrnnnTo download the full TIPS-090150 PDF, please click here.
