Research on a Kind of no Punch Hollow Part Hydraulic Pressure Expand Mould
Advanced Materials Research, 2014There are many kinds of expanding mould, and rubber punch is more than others. Of course there are many hydraulic pressure mould, but there are a litter of which can be multipurpose and be suit for many kinds of products. Through researching some kinds of products, using of a kind of called Half structure and a common use of die set, a kind of no punch

The concept is presented of a hydraulic short-stroke device that applies automatically a blank-holder force proportional to the punch force. The principle underlying the device is analyzed theoretically. The effects of various dimensions and the springs used on the punch force, the blank-holding force and the cycle time are determined.
