Ceramic particle filled composite wear-resistant sieve plate and manufacturing process thereof

Technical Field

The invention relates to the field of screening devices, in particular to a ceramic particle filled composite wear-resistant sieve plate and a manufacturing process thereof.

Background

The vibrating screen is a material grading device, which comprises an excitation device, a screen box, a screen plate and the like, wherein the screen box and the screen plate are driven to vibrate through the operation of the excitation device in the screening working process, material particles larger than the size of the screen holes are reserved on the screen surface, and material particles smaller than the size of the screen holes are screened out through the screen holes, so that the separation of materials is realized. The sieve plate is a key component in the vibration sieving equipment, and mainly plays a role in grading materials, and the abrasion is a main failure mode of the sieve plate.

In the commonly used sieve plate materials, high manganese steel is the most common metal material, and the high manganese steel material has the advantages that under the strong impact or heavy load working condition, due to the work hardening characteristic of the high manganese steel, the surface hardness of the high manganese steel is rapidly improved, but in the vibration sieving equipment, the impact force generated by the material is small, the work hardening effect is not obvious, the surface hardness of the high manganese steel is not enough to be obviously improved, and therefore under the sieving working condition, the high manganese steel material is quickly abraded due to insufficient hardness.

The polyurethane material is another common sieve plate material, and the polyurethane sieve plate is characterized by high wear resistance and long service life, but is expensive, and has lower sieving efficiency than a metal sieve plate due to lower opening rate than the metal sieve plate.

Therefore, it is necessary to develop a composite wear-resistant sieve plate with wear resistance, toughness, high overall strength and long service life.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides a ceramic particle filled composite wear-resistant sieve plate and a manufacturing process thereof, which can effectively prolong the service life of the sieve plate on the premise of maintaining higher sieving efficiency.

The purpose of the invention is achieved by the following technical scheme: the ceramic particle filled composite wear-resistant sieve plate mainly comprises a bottom plate and a wear-resistant layer, wherein a plurality of uniformly distributed round holes are punched on the bottom plate, bosses are formed on the edges of the round holes through flanging, flanges are machined on the periphery of the bottom plate through flanging, and cavities are formed between the bosses and the flanges and used for filling the wear-resistant layer.

The manufacturing process of the ceramic particle filled composite wear-resistant sieve plate comprises the following steps:

1. stamping: punching a plurality of uniformly distributed round holes on the bottom plate, flanging each round hole to form a boss, and flanging the periphery of the bottom plate to form a flange;

2. filling: uniformly stirring a mixture of ceramic ball particles and an adhesive, and filling the mixture into a cavity between the boss and the flange to form a wear-resistant layer;
