Abstract

The utility model discloses a sieve plate which comprises a plate body (1) and a handle (2). A plurality of through holes (3) are arranged in the plate body (1); and a closed baffle (4) is arranged at the edge of the body (1). Neodymium-iron-boron powder can be guaranteed to be uniformly added into a die; moreover, the powder on the sieve plate can be prevented from falling off from the edge of the sieve plate. The utility model belongs to the technical field of auxiliary equipment for dies.

Description

Sieve plate

Technical field

This practicality newly relates to a kind of sieve plate that material evenly falls of being convenient to.

Background technology

In the field of powder metallurgy, generally adopt the higher Nd-Fe-B magnetic material of magnetic to make magnetic product, in the prior art, most of mould that adopts comes the needed product of moulding.Such as when producing the strip product, the neodymium iron boron powder need be added in the middle of the mould, existing all is directly with spoon the neodymium iron boron powder to be added in the middle of the mould, the central neodymium iron boron powder of mould is inhomogeneous like this, the product defectiveness that final production is come out.

The utility model content

Technical problem to be solved in the utility model is: a kind of sieve plate is provided, can guarantees that the neodymium iron boron powder evenly is added in the mould.

Technical solution adopted in the utility model is: a kind of sieve plate, and it comprises plate body and handle, is furnished with a plurality of through holes on the described plate body, body edges is provided with closed guard.

The beneficial effects of the utility model are: the utility model sieve plate can guarantee that the neodymium iron boron powder evenly is added in the mould, and can also prevent that the powder on the sieve plate from dropping from the sieve plate edge.

Description of drawings

Fig. 1 is coated with the master mold schematic diagram for the utility model.

Among the figure, 1. plate body, 2. handle, 3. through hole, 4. baffle plate.

The specific embodiment

Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.

In conjunction with shown in Figure 1, a kind of sieve plate, it comprises plate body 1 and handle 2, is furnished with a plurality of through holes 3 on the described plate body 1, body 1 edge is provided with closed guard 4.Through hole 3 array settings on the described body 1, as shown in Figure 1.Handle 2 is fixedlyed connected with body 1, adopts screw bolt and nut that both are connected in the present embodiment.Baffle plate 4 is located at the edge of body 1, can find out as shown in Figure 1.

Operation principle of the present utility model is, is inverted the neodymium iron boron powder on sieve plate, and the operating personnel shakes sieve plate, and the neodymium iron boron powder will spill from the through hole on the body 13, enters in the corresponding mould.Owing to added sieve plate, so the neodymium iron boron powder in the mould will compare evenly, and the product quality that die sinking is at last come out is even.In addition, this practical sieve plate body 1 edge is provided with closed guard 4, promptly surrounds the ring of a sealing, therefore can also prevent that the powder on the sieve plate from dropping from the sieve plate edge.

Claims (1)

1. sieve plate, it is characterized in that: it comprises plate body (1) and handle (2), is furnished with a plurality of through holes (3) on the described plate body (1), body (1) edge is provided with closed guard (4).
