Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, and more specifically, relates to a grinding equipment for diamond-reinforced metal matrix composite materials. Background Technology

[0002] Diamond-reinforced metal matrix composites are a type of composite material formed by adding diamond particles into a metal matrix and then preparing it through specific processes. They combine the excellent properties of diamond, such as high thermal conductivity, high hardness, and high strength, with the good machinability and toughness of the metal matrix, thus demonstrating outstanding application performance in many fields. When grinding this composite material, appropriate grinding tools are necessary. However, in reality, most existing grinding tools only have one grinding cycle, which makes it difficult to achieve a uniform and thorough grinding effect. Furthermore, these grinding tools generally lack the function of screening grinding particles. As a result, the size control of the particles added to the metal matrix is ​​not strict enough, which can easily have an adverse effect on the properties of diamond-reinforced metal matrix composites. Utility Model Content

The lower end of the drive shaft extends out of the lower circular plate of the coarse grinding disc and is connected to the coarse grinding motor. The coarse grinding motor is fixed to the protective shell by fasteners.

[0006] Furthermore, a collection groove is provided on the side of the lower disc of the coarse grinding disc, and six sets of through holes are opened on the bottom surface of the collection groove, with a set of fine grinding discs correspondingly arranged below each set of through holes.

[0007] Furthermore, a feed inlet is provided in the middle of the upper disc of the fine grinding disc, and a drive shaft is provided in the middle of the feed inlet. The drive shaft is fixed to the upper disc of the fine grinding disc by six sets of connecting rods.

[0011] 2. This utility model uses gear meshing on the fine grinding discs, and only one motor is needed to drive six fine grinding discs. In this way, the overall structure can be reasonably simplified, which not only makes operation convenient, but also saves resources.

[0012] 3. This utility model uses a sieve to sieve the ground material particles. The material particles that meet the particle size standard can be discharged through the discharge cylinder, while those that do not meet the particle size standard are left on the upper side of the sieve. They are then removed and ground again. This method helps to improve the precision of the material particles. Attached Figure Description

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a diamond-reinforced metal matrix composite grinding equipment, including: a support leg 1; a protective shell 2 is provided above the support leg 1, and a feed trough 3 is provided above the protective shell 2. Three sets of crushing rollers 4 are installed inside the feed trough 3. The two ends of the three sets of crushing rollers 4 extend outward from the feed trough 3, and both ends are connected to a crushing motor 401. A discharge port 301 is provided at the lower end of the feed trough 3. A coarse grinding disc 6 is provided below the discharge port 301. A fine grinding disc 7 is provided below the coarse grinding disc 6. A discharge shell 5 is provided below the fine grinding disc 7. A discharge pipe 501 is provided on the front side below the discharge shell 5.

[0021] Among them, such as Figures 3 to 5As shown, a circular plate is provided at the middle position of the discharge port 301. This circular plate is fixed to the discharge port 301 of the feed trough 3 by six sets of connecting rods. A feed port 701 is provided at the middle position of the upper circular plate of the coarse grinding disc 6, and a drive shaft 601 is provided at the middle position of the feed port 701. The upper end of the drive shaft 601 overlaps with the lower side of the circular plate and is fixed to the upper circular plate of the coarse grinding disc 6 by six sets of connecting rods. The lower end of the drive shaft 601 extends out of the lower circular plate of the coarse grinding disc 6 and is connected to the coarse grinding motor 602. The coarse grinding motor 602 is fixed to the protective shell 2 by the fixing member 10. A collection groove 9 is provided on the side of the lower circular plate of the coarse grinding disc 6. Six sets of through holes 901 are provided on the bottom surface of the collection groove 9, and a set of fine grinding discs 7 are provided below each set of through holes 901. A feed port 701 is provided at the middle position of the upper circular plate of the fine grinding disc 7. A drive shaft 601 is located in the middle of the feed inlet 701. The drive shaft 601 is fixed to the upper disc of the fine grinding disc 7 by six sets of connecting rods. One set of drive shafts 601 located at the rear extends out of the lower disc of the fine grinding disc 7 and is connected to the fine grinding motor 801. The other drive shafts 601 extend out of the lower disc of the fine grinding disc 7 and are connected to the support bearing 802. The support bearing 802 is fixed to the protective shell 2 by the fixing member 10. By setting up crushing rollers, coarse grinding discs and fine grinding discs, the material is ground in a graded and progressive manner, which helps to improve the grinding accuracy. Gears 8 are set on the side of the upper disc of the fine grinding disc 7, and the gears 8 mesh with each other. Only one motor is needed to drive the six fine grinding discs 7. In this way, the overall structure can be simplified reasonably, which not only makes the operation convenient, but also saves resources.

[0022] Among them, such as Figure 2 and Figure 4 As shown, a screen 11 is provided in the middle of the rear side of the discharge shell 5, and a baffle 502 is provided on the discharge shell 5 behind the screen 11 to perform a sieving operation on the ground material particles. Material particles that meet the particle size standard can be discharged through the discharge cylinder, while those material particles that do not meet the particle size standard are left on the upper side of the screen, and then taken out and ground again. This practice helps to improve the precision of the material particles.

[0023] The specific usage and function of this embodiment are as follows: In this invention, all motors are turned on, and the material to be ground is poured into the feed trough 3. The crushing roller 4 performs initial crushing on the material. The crushed material enters the coarse grinding disc 6 through the discharge port 301 and the feed port 701 of the coarse grinding disc 6 for grinding. The ground material falls into the collection trough 9 and enters the fine grinding disc 7 through the through hole 901 and the feed port 701 of the fine grinding disc 7 for grinding again. The ground material falls into the discharge shell 5. The excessively coarse feed particles are left on the upper side of the screen 11, and the particles that meet the standard are discharged from the discharge cylinder 501. After grinding is completed, the baffle 502 is removed to collect the excessively coarse feed particles and grind them again.
