Description
Technical field
The utility model belongs to rare earth permanent magnet manufacturing equipment field, particularly relates to a kind of fully-automatic sealing press for neodymium-iron-boron rare earth permanent magnet.
Background technology
Nd-Fe-B rare-earth permanent magnet generally is divided into sintered magnet and bonded permanent magnet two classes, refers to sintered Nd-Fe-B permanent magnet here.Sintered Nd-Fe-B permanent magnet was invented in nineteen eighty-three, and suitability for industrialized production was in 1985.China and Japan are world sintered NdFeB majoies country of production.The characteristics of NdFeB magnetic powder are that easy oxidation, agglomeration are strong, mobile poor, so be difficult to realize accurate mass automation compacting.Patent CN1323915A (" powder pressing appts and use the manufacture method of the rare-earth magnet of this device ") provides a kind of volumetric method drawing-in device, the mass transport seal of tube, solved the anti-oxidation problem in the material conveying process, but material boots, press cartridge and former are exposed to directly in the air unreasonable.Because the material boots have magnetic and spill in the process of moving forward and backward unavoidablely, former is exposed to and means in the air that magnetic also is exposed in the air, and the meaning of the front mass transport seal of tube will reduce greatly like this.Owing to be subjected to the restriction of the mobile difference of NdFeB magnetic powder, the volume feed method can't be accomplished even, consistent between each mould weight at all.
Patent CN 101486096A (" oil press for automatically moulding rare-earth magnetic powder ") adopts complete closed inert gas shielding method to solve the problem of the easy oxidation of NdFeB magnetic powder.This patent adopts methods such as weight method, automatic die lubricate, and can realize automation feeding and compacting.But also there is open defect in this patent: 1) no sub-material middle transition cabin; 2) directly feeding is moved in vibration; 3) powder that weighs up is transferred to feeding boots and feeding by telescoping tube.
During no sub-material middle transition cabin, when the powder bucket hour (for example less than a 10kg) underlying material be subjected to gravity effect less, to weighing the influence of accuracy and uniformity less, but because the additional virgin material of bucket that will often reload, so efficient is too low.If there is not sub-material middle transition cabin, adopt big charging basket (about 200kg or about 500kg, to need not often to reload bucket again; the efficient height), underlying material is subjected to gravity effect bigger, and top layer and bottom powder density are inconsistent; very difficult realization is accurately weighed, and uniformity is also bad, is prone to the mistake of weighing.
Because the agglomeration of Nd-Fe-B powder is stronger, directly reconstructed image very easily appearred in the vibration feeder scales/electronic balance weighing, caused the outer batch turning of tolerance.
Because NdFeB magnetic powder very thin (3～5 μ m) easily sticks on the tube wall, the powder that weighs up very easily causes the phenomenon of " weigh accurately, but actual feeding being inaccurate " when being transferred to feeding boots and feeding by telescoping tube.
Summary of the invention

Hopper comb type micro mist constant-current stabilizer is installed on the described oscillating feeder, and comb type micro mist constant-current stabilizer links to each other with position sensor and motor, the position of conveniently adjusted comb type micro mist constant-current stabilizer.After adding this constant-current stabilizer, weighing device is regulated easily when changing the compacting specification each time, and error rate is low when weighing, accuracy is high.
Described weighing system is arranged on after the hopper comb type micro mist constant-current stabilizer, described oscillating feeder includes charging aperture, discharging opening, hopper comb and electromagnetic shaker, wherein the discharging opening place is provided with that drawer type connects material and feeding hopper, described feed system be arranged on that drawer type connects material and feeding hopper after, before the dc source Magnetic field press, described dc source Magnetic field press top is provided with the compression moulding system, the releasing agent sprayer unit is installed on the press of compression moulding system, and compression moulding system below is provided with the blank ejecting device.
Described hopper comb type micro mist constant-current stabilizer inside is provided with waveform current stabilization structure, and described weighing system includes electronic balance.
Described drawer type connects material and feeding hopper comprises the drawer type material receiver of round barrel shape feeding hopper and below thereof, and its material is a polishing stainless steel.Simplicity of design, no material adhesion.
Described releasing agent sprayer unit following spray sprayer unit.Releasing agent after the atomizing can evenly be coated in cavity surface, need not manually to smear, no drip phenomenon, and the releasing agent consumption is few, saves cost.
The front portion of described blank ejecting device is equipped with padded coaming, finishes the efficient height during release with feeding.Pressed compact is pushed directly on the conveyer belt, takes bagging area to by conveyer belt.
Beneficial effect
