The permanent magnet wet molding hydraulic machine comprises a mold and a mold base. The mold includes a female mold, a male mold and a mold cavity mold, and the mold cavity mold sleeves the periphery of the male mold, matches with the female mold and the male mold to form a mold cavity and is fixedly mounted on the mold base. Therefore, the height of the feed in the mold cavity can be controlled accurately, and the green bodies are good in uniformity, small in deviation and high in quality.
Description
Technical field
The utility model belongs to permanent magnetism Wet-pressing molding field, relates to a kind of permanent magnetism Wet-pressing molding hydraulic press specifically.
Background technology
China has become magnetic materials production big country, its output has accounted for more than 60% of the whole world, domestic have family surplus the permanent magnetism manufacturing enterprise 300 at present, the production of ferrite permanent-magnet materials has the preparation of hydrous slurry, Wet-pressing molding, sintering, mill processing, go-on-go, pack several big operations, wherein Wet-pressing molding is critical process, its investment will account for the over half of whole production line, the quality of moulding press is directly connected to the green compact performance, efficient and benefit, extremely manufacturing enterprise's concern of Wet-pressing molding press for this reason, 90 year initial stage, relevant large enterprise introduces Germany respectively, the forming hydraulic press that the U.S. and Japan produce, development to China's permanent magnetism industry has bigger facilitation, but for a long time, is that import or homemade Wet-pressing molding hydraulic press all are floating type moulding, be that upper cylinder compressing mold cavity floats downwards, lower die head maintains static, and forces the die cavity volume reducing, and the moisture in the permanent magnetism slip is extruded and moulding.
Yet existing Wet-pressing molding hydraulic press is difficult to accurately control the work loading height of slip in the die cavity because die cavity floats, and the green compact thickness deviation of moulding is bigger, and uniformity is poor.
The utility model content
For overcoming the defective that prior art exists, the utility model provides a kind of permanent magnetism Wet-pressing molding hydraulic press, has the green compact high conformity, deviation is little, the characteristics that quality is high.
For achieving the above object, the technical scheme that adopts of the utility model is:
Permanent magnetism Wet-pressing molding hydraulic press comprises mould and die holder, and described mould comprises die, punch and swaging die, and described swaging die is enclosed within the periphery of punch, cooperates with die and punch to form die cavity, and it is characterized in that: described swaging die is fixedly mounted on the die holder.
Further, described die holder is installed on the machine base.
Further, described mould is located at the pressure-bearing oil cylinder and stretch between the oil cylinder on the top, and the pressure-bearing oil cylinder is positioned at the mould top, and the top is stretched oil cylinder and is positioned at the mould below.
Further, described die is provided with at least one limbers, and described limbers is communicated with the negative pressure of vacuum jar.
Compared with prior art, the utlity model has following beneficial effect:
One, permanent magnetism Wet-pressing molding hydraulic press of the present utility model comprises mould and die holder, and mould comprises die, punch and swaging die; Swaging die is enclosed within the punch periphery, cooperates with die and punch to form die cavity, and swaging die is fixedly mounted on the die holder.The utility model can be controlled the work loading height of slip in the die cavity accurately, thereby make the green compact high conformity by swaging die is fixedly mounted on the die holder, and deviation is little, the quality height.
Two, the utility model is fixedly mounted on swaging die on the die holder, compares with existing floating type permanent magnetism Wet-pressing molding hydraulic press, has reduced mould bases, has reduced the labour intensity of die manufacturing cost and mould assembling level Installation and Debugging; Also reduced the height of permanent magnetism Wet-pressing molding hydraulic press complete machine simultaneously, our experiments show that, the floating type low 250-280mm of base aspect ratio that gets of the present utility model, active station just can be operated and be debugged on the ground, reduce the work of fabrication and installation hole and pedal, reduced cost.
Three, mould of the present utility model is located between pressure-bearing oil cylinder and the roof pressure oil cylinder, and the pressure-bearing oil cylinder is positioned at the mould top, and the top is stretched oil cylinder and is positioned at the mould below.In the time of Wet-pressing molding, the pressure-bearing oil cylinder is motionless, and the top is stretched oil cylinder and moved upward and finish Wet-pressing molding.By this lower top type Wet-pressing molding, material movement is identical with the direction that moisture is extruded, and magnetic shoe green compact inner arc surface reaches density earlier, outer arc reaches pressed density at last, and moisture is extruded and passed through easily, so molding time reduces, the corresponding minimizings of defective such as while blank crackle, quality and the efficient of blank production obviously improve, and the results showed, production efficiency of the present utility model enhances productivity 20% than floating type permanent magnetism Wet-pressing molding hydraulic press.
Four, die of the present utility model is provided with at least one charging hole, and the limbers is communicated with the negative pressure of vacuum jar, reaches self-draining purpose by the negative pressure of vacuum jar.
