Abstract
The numerical control hydraulic pressure double action stretcher is a kind of equipment to complete the metals lamella to pull to stretch, belonging to grind to press the machine technique realm.
That machine mainly includes the stretching and beading oil urn which respectively installing in the top of the machine and a bottom of the machine, the pillar and installing in sign pillar of pressing the side bedplate, to link piston pole of descending the oil urn under the work pedestal and hydraulic system。Five-pivot, double-curved bar, oblique arrangement, mode-locked device, fast toggle speed, no shock. The work is divided into four steps: press the side, pull to stretch, return journey and open the mold.
Mainly it is applicable to various metals lamella to pull to stretch to take shape, and pull to stretch to model the craft deeply such as the different materials, like aluminum plank, coin and the stainless steel plank...etc.
