Full servo automatic press

Abstract

The invention discloses a full servo automatic press. The full servo automatic press comprises a rack, wherein a charging bucket, a powder weighing device, a feeding device and a molding device are hermetically arranged on the rack, the charging bucket is arranged above the powder weighing device, the molding device comprises a molding die, a guide pillar, a top plate, a base plate, an upper punch, a lower punch and a magnetic field coil, the top plate and the base plate are fixedly arranged at the upper end and the lower end of the guide pillar, the die is arranged on the base plate by virtueof a die set, the upper punch and the lower punch are respectively located at the upper end and the lower end of the molding die, the magnetic field coil is located beside the molding die, the upperpunch comprises an upper electric cylinder and an upper die, the upper electric cylinder is fixedly arranged on the top plate, the output end of the upper electric cylinder is connected with the upperdie, the upper die is located above the molding die, the lower punch comprises a lower electric cylinder and a lower die, the lower electric cylinder is fixedly arranged on the base plate, the outputend of the lower electric cylinder is connected with the lower die, and the lower die is located below the molding die. The full servo automatic press disclosed by the invention has the advantages that hydraulic oil cylinders are replaced by virtue of the electric cylinders, using effect is good, control accuracy is high, pressing effect is good, defects are hardly produced, and rejection rate islow.

Description

technical field [0001] The invention relates to the technical field of forming presses, in particular to a full-servo automatic press. Background technique [0002] The magnetic field molding press mainly includes a sealed frame, which is equipped with a powder weighing device, a feeding device and a molding device. The NdFeB powder first enters the powder weighing device through the barrel, and the powder weighing device weighs the quantitative NdFeB powder. Then put it into the feeding device, and finally push it to the molding device by the feeding device, and put the NdFeB powder into the molding mold, and then press the NdFeB powder. [0003] The powder weighing device is an important part of the NdFeB powder magnetic field forming press. The feeding process of the NdFeB forming press includes: the NdFeB powder first enters the weighing device through the barrel, and the weighing device weighs the quantitative NdFeB The powder is then loaded into the powder feeding dev...
