The friction plate powder blanking equipment provided by the utility model, when blanking, firstly, there are more powder raw materials in the hopper 1, and it can be replenished manually or by equipment as the use increases. Secondly, when workers need to use powder raw materials, they only need to manually rotate the outer blanking baffle 5, and make the blanking baffle 5 on one side of the limit plate 7 rotate downward; wherein the powder is under the action of gravity It can fall into the space formed by the limit plate 7 and part of the blanking baffle 5, and when the blanking baffle 5 is turned, part of the powder can be allowed to fall downwards and be taken over by the worker; due to the adjacent The space enclosed between the two blanking baffles 5 and the blocking plate 8 is relatively close, so after each rotation of the blanking baffle 5 is rotated, powders with a relatively close quality can be dropped, thereby better Guarantee the quality of friction plate blanks.

Simultaneously because the worker only needs to rotate the external blanking baffle plate 5 to make the powder material fall, therefore the speed of powder material measurement is improved, that is, the production speed is improved. Among them, during the blanking process, a space with certain airtightness can be formed between the blanking baffle plate 5, the edge plate 6, the limit plate 7 and the blocking plate 8, so that the powder can only fall downwards and prevent the powder from falling. Floating everywhere; secondly, the damping plate 9 and the edge plate 6 have a close force, so when the blanking baffle 5 is not rotated, the edge plate 6 at this time can be pressed by the damping plate 9, It cannot be rotated, so it can prevent the powder from falling spontaneously. Simultaneously, the minimum distance between the blanking baffle plate 5 and the blocking plate 8 is less than 2mm, which can be set to be tangent or fit between the track of the spacer plate 7 and the blanking baffle plate 5 according to actual conditions, so it can be further improved Reduce the powder falling out. Simultaneously in actual production, unavoidably have powder to spill out, therefore also can be provided with receiving container or dedusting pipe below the blanking baffle 5. At the same time, the support columns 3 are externally connected with brackets for supporting them, and the support columns 3 and the brackets are fixedly connected by bolts, that is, the support columns 3 cannot rotate.

The accommodating portion 1a has a larger cross section, so it can add more powder at one time, reducing the total number of times of adding powder, and at the same time ensuring that the powder can continue to fall out. Secondly, the cross-section of the transition part 1b is small, and the powder does not have good fluidity like water, so when the cross-section is small, and it is V-shaped or S-shaped, it can better transfer the powder The pressure is transmitted to the inner wall of the transition part 1b, and the pressure of the powder on the blanking baffle 5 is reduced, ensuring that the blanking baffle 5 can maintain positional stability when it does not rotate. At the same time, the dispersion column 10 can not only support the powder, slow down the falling speed of the powder, and improve the strength of the accommodation part 1a, but also can separate the powder. If the powder is agglomerated, it can It is not that the dispersing column 10 is dispersed and then dropped.

When the powder falls out from the blanking plate, it falls into the top opening of the material guide shell 11 after being guided and limited by the blanking plate and the limiting plate 7, the blocking plate 8 and the edge plate 6, And fall out from the bottom of the material guide shell 11 to the outside, after the worker uses the container below to accept, transfer to the required mold place. Wherein the bottom opening of the material guide shell 11 is relatively small, which can make the powder fall into the container better and reduce the powder from being emitted to the outside.

Among them, in actual use, the edge plate 6 is driven by the blanking baffle 5 to rotate; and the matching hole 13 in the middle of the edge plate 6 is limited by the anti-rotation groove 12, so it cannot rotate; so during use , the edge plate 6 can realize relative sliding between the damping plates 9 . Moreover, since the elastic member 15 is continuously in a compressed state, the pressure exerted by the solid damping plate 9 on the edge disk 6 also exists objectively and continuously.

As the use time increases, the elastic force of the elastic member 15 weakens. At this time, after the positioning nut is removed, the positioning bolt is taken out, and then the stopper 14 is slid along the length direction of the anti-rotation groove 12 until the elastic force of the elastic member 15 is suitable. Finally, pass the positioning bolt through the positioning hole 16 on the stopper 14 and the positioning hole 16 on the support column 3, and connect the positioning nut, and the adjustment is completed. If there is no suitable positioning hole 16 on the support column 3 at a certain position, continue to move the stopper 14 toward the direction of compressing the elastic member 15 until there is a suitable positioning hole 16 . Such an elastic member 15 can have a longer service life, reducing the number or frequency of discarding or replacing the elastic member 15 .

Wherein the quantity of the blanking baffle 5 in the present embodiment can be selected according to actual processing situation and personal operating habit; If select the blanking baffle 5 that quantity is less, such as 4-6, when rotating to certain After the angle is adjusted, the powder that is rotated to fall can fall down faster. However, if you choose a large number of blanking baffles 5, such as 10-12, when the bottom powder is received once, put an empty container under the material guide shell 11, and then directly rotate the blanking After the baffle 5 reaches a certain angle, other operations are performed directly; while other operations are being performed, the powder can slowly fall out from between the blanking baffles 5, and the next time the worker needs to use the powder again , at this time the falling powder has all fallen out.

It should be noted that each embodiment in this specification is described in a progressive manner, each embodiment focuses on the differences from other embodiments, and the same and similar parts of each embodiment can be referred to each other.

The above description is only a description of the preferred embodiments of the present utility model, and is not any limitation to the scope of the present utility model. Any changes and modifications made by those of ordinary skill in the field of the utility model according to the above disclosures all belong to the protection scope of the claims .
