Technical field
The utility model relates to a kind of magnet compacting tool set, particularly a kind of circular ring magnet compacting tool set.
Background technology
In recent years, along with the high speed development in the fields such as computer, video recording and communication apparatus, equipment is set up to the microminiaturized development of miniaturization, and the miniaturization of thing followed magnetic fittings and high-precision requirement are just more and more higher.Usually the production of magnetic material will be passed through the operations such as blank moulding, sintering, attrition process, air gap processing and just can obtain final finished product.In the blank operations for forming, normally adopt powder compressing through mould, this moment, mould action just seemed particularly important, misoperation can cause Lou material, pore, mix the problem that impurity etc. affects the magnet Performance and quality.
The utility model content
For addressing the above problem, the utility model discloses a kind of circular ring magnet compacting tool set, the external mold with the material chamber by arranging, be oppositely arranged on internal mold and core rod in the material chamber, not only effectively improved compacting efficient and the compacting quality of circular ring magnet blank, the core rod of also being convenient to simultaneously by changing different size changes the circular hole size of circular ring magnet.
The disclosed circular ring magnet compacting tool set of the utility model, comprise the external mold that is provided with square material chamber, be oppositely arranged on two internal molds and core rod in the external mold, described core rod is arranged on the center of bottom, material chamber, one end of described internal mold is that the square other end is the semicircle of indent, described internal mold all is movably arranged in the material chamber and the Mould Breadth of internal mold adapts with the width of expecting the chamber, a semicircular end of described internal mold all arranges relatively, and the length in described material chamber is greater than the length sum of two internal molds.The disclosed circular ring magnet compacting tool set of the utility model, the internal mold that adapts by the material chamber width that arranges with external mold, not only made things convenient for the compacting of magnet blank, easy to operate, can also be convenient to simultaneously adjust the size of blank circular hole by changing the core rod of different size, make things convenient for the compacting of mould to the different model product blank, improve the service efficiency of equipment, reduced the equipment cost of enterprise.
A kind of improvement of the disclosed circular ring magnet compacting tool set of the utility model, described material chamber bottom centre place also is provided with the draw-in groove with internal thread, and the lower end of described core rod is provided with connecting screw rod, and described draw-in groove and connecting screw rod are equipped with.This improvement arranges the connecting screw rod that is equipped with draw-in groove by the lower end at core rod, not only made things convenient for the fixing and location of core rod, also be convenient to as required core rod be changed, satisfy different product to the needs of the type in aperture and hole, improved flexibility and the practicality of mould compacting blank.
The disclosed circular ring magnet compacting tool set of the utility model, by external mold, internal mold and the core rod that arranges, made things convenient for the compacting of bar magnet blank with holes, simple in structure easy to operate, can also cross simultaneously and change as required the compacting that model adapts to the blank of different demands, improve the compacting quality of compacting precision and blank, also avoided simultaneously the waste of powder, reduced the production cost of enterprise.
