"LP" link press can be first move the slide toward the work piece at high speed and get work done at low speed before quickly retrieving the slide. As the slide slows down upon moving to the walking zone during the stroke, the vibration, noise, and heat generated from the friction between the workpiece are much less when compared with other brand crank presses. Consequently, die molding service life is prolonged and operating environment is improved as well. Further, upon drawing, the effective working area is wider than crank press, thus reducing the time of the pressing processes. For example conventional cross – shift press require 2-3 processes to complete the deep joint, while the “LP” only needs 1-2 processes . This even increase the rigid of workpieces. Production rates are not adversely affected by the change of stroking rates.
