All-electric presses get direct-drive upgrade.The Elma all-electric machine series from Negri Bossi USA, Newark, Del., has been renamed and upgraded for faster injection, more precise and repeatable movements, and reduced maintenance. In particular, direct-drive clamping has been extended to larger models. The new Canbel VE line will make its worldwide debut at the upcoming NPE NPE NullPointerException (Java) NPE Network Processing Engine NPE National Policy on Education NPE National Plastics Exposition NPE Natural Penis Enlargement NPE Nutrition Program for the Elderly show in Chicago in June. The series includes 11 models from 77 to 935 tons. Each model has four Siemens servo An electromechanical device that uses feedback to provide precise starts and stops for such functions as the motors on a tape drive or the moving of an access arm on a disk. motors, one each for the clamp and ejection ejection /ejec·tion/ (e-jek´shun) 1. the act of casting out or the state of being cast out, as of excretions, secretions, or other bodily fluids. 2. something cast out. 3. , while the injection unit has two servo motors arranged one behind the other and coupled directly to the screw. Negri Bossi now also uses direct drive on the toggle To alternate back and forth between two states. toggle - To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from "toggle switches", such as standard light switches, though the word "toggle" actually refers to clamp of machines from 300 tons on up (previously it was used only on smaller models). Direct drive provides higher clamp speeds than before on the larger presses. The servo motors have an "energy return system," which recaptures energy used while braking (decelerating) the motor. Negri Bossi says this provides a 2.3% energy return. The Canbel VE series is reportedly unique in having separate lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of systems for the ballscrew and toggle, which allows using different lubricants lubricants preparations for the lubrication of passages to reduce frictional injury, e.g. oily preparations, including petroleum jelly, lanolin or water-soluble preparations such as methyl cellulose. appropriate to each function. Controls have been upgraded to allow users to create custom-configured screens. The Canbel line uses the same base frame as Negri Bossi's Canbio hydraulic machines, which reduces the overall cost of the new press line. It also allows customers to combine features of the Canbio and Canbel presses to yield hybrid designs. Tel: (302) 737-8001 * PT Direct: 259XF |
