Abstract
The utility model relates to a moulding device for a rare-earth permanent-magnet tile-shaped product, comprising a left pole column and a right pole column, wherein a female die is tightly clamped between the left and right pole columns; the innovative points are as follows: a lateral cylinder is connected to the left pole column or the right pole column, and the lateral cylinder can push the left pole column or the right pole column to horizontally move towards the female die or retreat; and the female die is formed by movably connecting a left half female die with a right half female die, and a reset spring for expanding the left and right half female dies is disposed at the boundary of the left half female die and the right half female die. The moulding device for a rare-earth permanent-magnet tile-shaped product disclosed by the utility model has the advantages that: in the case of pressing, a piston rod of the lateral cylinder pushes the left pole column or the right pole column to tightly clamp the female die to press; in the case of de-moulding, the lateral cylinder drives the left and right pole columns to slightly retreat, so that the left and right half female dies are slightly separated under the function of the reset spring; the resistance on a product by the female die is greatly reduced; in this way, the product is smoothly de-moulded, and the damage to the product is avoided.
Description
Technical field
The utility model relates to a kind of rare-earth permanent magnetic tile shape formed product device, the rare-earth permanent magnetic tile shape formed product device of fragile product not during the particularly a kind of demoulding.
Background technology
Along with the development and the maturation of PM technique, increasing material adopts PM technique to make.It becomes pie through powder shaping press with powder compaction earlier, makes final products through sintering again.Rare earth permanent-magnetic material is a kind of comparatively special material, and the alloy that it forms samarium, neodymium mixed rare-earth metal and transition metal (like cobalt, iron etc.) is with powder metallurgy process compacting die mould and sintering, a kind of magnetic material that after magnetizing in magnetic field, makes.The former of rare-earth permanent magnetic tile shape product clamps through symmetrically arranged left pole, right pole, during the demoulding, realizes the demoulding by the product in the former of having rushed to summit down.Because it is bigger that product receives the resistance of former, cracking, arrisdefect phenomenon usually appear in product when the demoulding, cause qualification rate to descend, the waste resource.
Summary of the invention
The rare-earth permanent magnetic tile shape formed product device of fragile product not when the technical problem that the utility model will solve provides a kind of demoulding.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of rare-earth permanent magnetic tile shape formed product device, comprise left pole, right pole, and clamping between the said left and right pole has former; Its innovative point is: be connected with a side cylinder on said left pole or the right pole, this side cylinder can promote left pole or right pole level and move or retreat to former; Said former is constituted by an active connection by a left side half former and right half former, and a said left side half former and right half former intersection are provided with the back-moving spring that left and right half former is strutted.
The advantage of the utility model is: during compacting, the piston rod of side cylinder promotes left pole or right pole is suppressed the former clamping.During the demoulding, the side cylinder drives left and right pole and retreats slightly, makes left and right half former under action of reset spring, separate slightly, significantly reduces the resistance of former to product, makes the smooth demoulding of product, avoids the damage of product.
Description of drawings
Fig. 1 is the utility model rare-earth permanent magnetic tile shape formed product apparatus structure sketch map.
Fig. 2 is a former vertical view in the utility model.
The specific embodiment
Shown in accompanying drawing, comprise left pole 1, right pole 2, former 3, side cylinder 4.
Clamping between above-mentioned left pole 1 and the right pole 2 has former 3, is provided with a side cylinder 4 in the outside of left pole 1, and the piston rod of this side cylinder 4 is connected with left pole 1 to be fixed, and can promote left pole 1 level after 4 startups of side cylinder and move or retreat to former 3.
As shown in Figure 2, former 3 is constituted by an active connection with right half former 32 by a left side half former 31, and left half former 31 and right half former, 32 intersections are provided with the back-moving spring 33 that a left side half former 31, right half former 32 are strutted.
During compacting; The piston rod of side cylinder 4 promotes left pole 1 former 3 clampings is suppressed, and during the demoulding, the side cylinder drives left pole 1 and retreats slightly; Make left half former 31 and right half former 32 under back-moving spring 33 effects, separate slightly; Significantly reduce the resistance of 3 pairs of products of former, make the smooth demoulding of product, avoid the damage of product.
