Abstract
The utility model provides a pushing device for a sintered Nd-Fe-B magnetic core. The pushing device comprises a pushing board body, and the upper surface of the pushing board body is provided with three circles of oval grooves and a *-shaped groove formed by a longitudinal groove, a transverse groove and an inclined groove. The lower surface of the pushing board body is provided with two circles of oval grooves and a *-shaped groove formed by a longitudinal groove, a transverse groove and an inclined groove. The cross section of each oval groove, the cross section of each longitudinal groove, the cross section of each transverse groove and the cross section of each inclined groove are trapezoid. According to the pushing device for the sintered Nd-Fe-B magnetic core, specific grooves are formed in the pushing device, the width and the thickness of each groove are designed according to the practical test, and accordingly the service life of a pushing board can be prolonged to the maximum extent.
Description
technical field
The utility model relates to magnet and manufactures plant-scale equipment field, particularly a kind of sintered NdFeB magnetic core pushing equipment.
Background technology
Ndfeb magnet, has the advantages that volume is little, lightweight and magnetic is strong, is the magnet of ratio of performance to price the best up to now.Ndfeb magnet is as third generation rare earth permanent-magnetic material, there is very high performance, be widely used in the industries such as the energy, traffic, machinery, medical treatment, IT, household electrical appliances, particularly along with the development of the information technology kownledge economy that is representative, constantly bring new purposes to the functional materials such as rare earth permanent magnet neodymium iron boron industry, this brings more wide market prospects for neodymium iron boron industry.Ndfeb magnet is the tetragonal crystal being formed by neodymium, iron, boron (Nd2Fe14B).In nineteen eighty-two, the assistant river true man of Sumitomo particulate metal (Masato Sagawa) find neodium magnet.The magnetic energy product of this magnet (BHmax) is greater than SmCo magnet, is the whole world material of magnetic energy product maximum at that time.Afterwards, Sumitomo particulate metal developed successful powder metallurgic method (powder metallurgy process), and General Motors Corporation develops successful churning smelting process (melt-spinning process), can prepare ndfeb magnet.Ndfeb magnet can be divided into two kinds of Agglutinate neodymium-iron-boron and sintered NdFeBs.In fact bonding is exactly injection mo(u)lding, and sintering is to vacuumize by high-temperature heating moulding! Ndfeb magnet is the strongest permanent magnet of magnetic now, is also the rare-earth magnet (rare earth magnet) the most often using, is widely used in electronic product, for example hard disk, mobile phone, earphone and battery-powered instrument etc.Ndfeb magnet needs to carry out sintering processing in the course of processing, adds man-hour due in expanding with heat and contract with cold, so push pedal there will be fracture, and useful life is often limited.
Utility model content
For above problem, the utility model is a kind of sintered NdFeB magnetic core pushing equipment, have specified channel thereon, and test designs grooved width and thickness according to reality, thereby can improve to greatest extent the useful life of push pedal, for reaching this object, the utility model provides a kind of sintered NdFeB magnetic core pushing equipment, comprise push pedal main body, described push pedal main body upper surface has three circle oval groove and cannelures, transverse groove and skewed slot form rice word groove, described push pedal main body lower surface has two circle oval groove and cannelures, transverse groove and skewed slot form rice word groove, described oval groove, cannelure, transverse groove and skewed slot cross section are trapezoidal.
As further improvement of the utility model, described oval groove, cannelure, transverse groove and skewed slot groove depth are 2-3cm, and the utility model groove depth can not be excessively shallow, cross shallow effect bad, cross dark push pedal and easily rupture.
As further improvement of the utility model, described each surperficial every circle oval groove cross section is descending reduces gradually, because inner ring expands comparatively severely, outer ring is expanded less, so oval groove cross section is descending should reduce gradually.
The utility model is a kind of sintered NdFeB magnetic core pushing equipment, have according to certain rules multi-turn oval groove thereon, positive and negative oval groove dislocation design, each oval groove also has skewed slot to be connected by transverse groove, cannelure, and afterwards grooved width and thickness is carried out to effective limit after tested, after this design, the useful life of push pedal extends greatly.

Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail:
The utility model is a kind of sintered NdFeB magnetic core pushing equipment, has specified channel thereon, and test designs grooved width and thickness according to reality, thereby can improve to greatest extent the useful life of push pedal.
As a kind of specific embodiment of the utility model, the utility model provides and uses schematic diagram a kind of sintered NdFeB magnetic core pushing equipment as shown in Figure 1, comprise push pedal main body 1, described push pedal main body 1 upper surface forms rice word groove by three circle oval grooves 5 and cannelure 2, transverse groove 3 and skewed slot 4, described push pedal main body 1 lower surface forms rice word groove by two circle oval grooves 5 and cannelure 2, transverse groove 3 and skewed slot 4, and described oval groove 5, cannelure 2, transverse groove 3 and skewed slot 4 cross sections are trapezoidal.
As a kind of best specific embodiment of the utility model, the utility model provides and uses schematic diagram a kind of sintered NdFeB magnetic core pushing equipment as shown in Figure 1, comprise push pedal main body 1, described oval groove 5, cannelure 2, transverse groove 3 and skewed slot 4 groove depths are 2-3cm, the utility model groove depth can not be excessively shallow, cross shallow effect bad, crossing dark push pedal easily ruptures, described push pedal main body 1 upper surface has three circle oval grooves 5 and cannelure 2, transverse groove 3 and skewed slot 4 form rice word groove, described push pedal main body 1 lower surface has two circle oval grooves 5 and cannelure 2, transverse groove 3 and skewed slot 4 form rice word groove, described oval groove 5, cannelure 2, transverse groove 3 and skewed slot 4 cross sections are trapezoidal, described each surperficial every circle oval groove 5 cross sections are descending reduces gradually, because inner ring expands comparatively severe, outer ring is expanded less, therefore oval groove 5 cross sections are descending should reduce gradually.
The above; it is only preferred embodiment of the present utility model; be not the utility model to be done to the restriction of any other form, and according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
