Description

Ceramic grinding wheel compression molding device

Technical Field

The utility model belongs to emery wheel processing production facility field, in particular to vitrified grinding wheel press forming device.

Background

The grinding wheel is also called a consolidation grinding tool, and is a consolidation grinding tool which is formed by consolidating common grinding materials into a certain shape (mostly circular, with a through hole in the center) by a binding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classifications of binders, ceramic grinding wheels, resin grinding wheels and rubber grinding wheels are common. The ceramic bond diamond grinding wheel has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, difficult heating and blockage in the grinding process and small thermal expansion.

In the production process of the ceramic grinding wheel, the materials are required to be pressed and formed after the materials are mixed. The general molding and pressing equipment performs compression molding by pressing a pressing head after filling materials into a die. For example, CN203495787U discloses a grinding wheel press forming machine, which includes a frame, a guide rail frame disposed above the frame, a power device connected to the guide rail frame, and a plurality of grinding wheel forming molds disposed between the guide rail frame and the frame, wherein the guide rail frame includes longitudinal guide rails disposed on both sides of the frame, and a transverse guide rail disposed between the longitudinal guide rails and moving up and down relative to the longitudinal guide rails, and the transverse guide rail is provided with a movable slide block; the grinding wheel forming die comprises a die sleeve with a core rod and a lower cover plate and an upper cover plate arranged above the die sleeve, and the upper cover plate is fixedly connected with the movable sliding block. The power device comprises a first air cylinder connected with the movable sliding block and a second air cylinder connected with the transverse guide rail.

However, after the conventional press forming equipment completes the pressing, the press formed grinding wheel blank is not easy to take out, and the grinding wheel blank is easy to damage when being taken out.

When the material powder is poured into the mold, the material is too concentrated and is not easy to be uniformly distributed. The conventional surface scraping can only ensure that the powder on the surface is scraped off, the uniformity of the material on the lower layer cannot be ensured due to the bridge phenomenon, the material on the place with a possibly serious bridge is virtual, the material on other places is real, and the non-uniformity of the virtual and real materials can directly cause the non-uniformity of the strength and the hardness of the product, so that the product quality is unstable.
