Abstract
The utility model discloses a die of magnetic-field formed square billets for sintering neodymium iron boron. The die comprises front and rear magnetic conductive plates and left and right side plates. The inner side faces of two ends of the front and rear magnetic conductive plates are respectively provided with grooves, two ends of the left and right side plates are respectively and correspondingly inserted into the grooves of the inner side faces of two ends of the front and rear magnetic conductive plates to form the die cavity, and the inner sides of the front and rear magnetic conductive plates and left and right side plates are respectively provided with front, rear, left and right wear resistant layers which are assembled or formed integrally to form an annular structure and which around the periphery of the die cavity; the lengths of the front and rear wear resistant layers are equal to the length of the die cavity, the lengths of the left and right wear resistant layers are larger than the width of the die cavity. The die is reasonable in structure, the shapes of the wear resistant layers are changed in a manner of assembling or forming integrally, the wear resistant layers on the inner sides of the side plates are enlarged, the widths of the wear resistant layers are larger than the width of the die cavity, and the magnetic-field defects at the corners when square billets are formed are optimized, and defects formed at the edges and corners of products are avoided.
Description
Technical field
The utility model relates to the mould of a kind of sintered NdFeB pressing under magnetic field square material base.
Background technology
Sintered NdFeB, need to be through the technical process of melting-powder process-pressing under magnetic field-sintering in the time making.Wherein, in the time that pressed by powder becomes blank, complementary field to complete magnetic orientation, be called pressing under magnetic field.Due to the requirement of pressing under magnetic field, side plate that the magnetic conductive board (mild steel) that its compressing mould is generally made up of soft magnetic materials and non-magnet_conductible material (stainless steel) form forms, and mould intracavity wall is inlayed the service life that the material of hardness high abrasion improves product.
In prior art, the shortcoming of this mould is: in the time of pressing under magnetic field, the magnetic line of force of square material base edge is non-parallel in the direction of magnetic field orientating, makes the edge of product form defect.
Utility model content
The purpose of this utility model is to provide the mould of a kind of sintered NdFeB pressing under magnetic field square material base, adopt splicing or integrated mode to change the shape of wearing layer, extend the wearing layer of side plate inner side, make its length exceed the width of die cavity, to improve the magnetic direction of square material base in moulding Shi Qi corner, the defect of avoiding product edge to form.
The technical solution of the utility model is as follows:
The mould of pressing under magnetic field square material base for a kind of sintered NdFeB, before including, rear magnetic conductive board and a left side, right plate, before described, on the medial surface at rear magnetic conductive board two ends, be respectively equipped with fluting, a described left side, the two ends corresponding intercalation of difference of right plate is front, in fluting on the medial surface of rear magnetic conductive board two ends and surround die cavity, it is characterized in that: before described, rear magnetic conductive board and a left side, before the inner side of right plate has respectively, after, left, right wearing layer, before described, after, left, right wearing layer is by mutual splicing or one-body molded formation loop configuration and be centered around the surrounding of die cavity, wherein, the length of rear wearing layer equals the length of die cavity, left, the length of right wearing layer is greater than the width of die cavity.
The mould of pressing under magnetic field square material base for described sintered NdFeB, is characterized in that: the thickness of described front, rear, left and right wearing layer is 0.01-20mm.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, adopt splicing or integrated mode to change the shape of wearing layer, the wearing layer of prolongation side plate inner side, makes its length exceed the width of die cavity, improve the magnetic field defect of square material base in moulding Shi Qi corner, the defect of having avoided product edge to form.
