Description

Alloy bearing device

Technical Field

The utility model belongs to the technical field of the frock utensil technique and specifically relates to an alloy bears device.

Background

Cemented carbide is the most widely used material for cutting tools, wear parts, mining tools, and is also called "industrial teeth" because of its high hardness, high strength, and high wear resistance. The main production process of the hard alloy comprises three procedures of preparation of raw materials, compact forming and sintering. The sintering process is the last process in the production of the hard alloy, which means that the hard alloy compact is subjected to high-temperature reaction at the temperature of 1350-. Because the temperature in the sintering process is too high, the hard alloy pressed compact is easy to chemically react with sintering devices of various common contact materials, so that the product structure is fundamentally changed, and the product quality is unqualified.

At present, in order to prevent bonding, one or more layers of anti-bonding materials are brushed on the surface of a blank sintering bearing device (used for bearing a hard alloy compact in the sintering process) of the hard alloy. Several layers of chemical coatings are manually brushed on the surface of the alloy bearing device, and the chemical coatings are adhered to the alloy bearing device after being naturally air-dried. Generally, drill teeth with different shapes and sizes are mounted on a drill according to the size and the specification of the drill, so that hard alloy parisons are different in size, but alloy bearing devices are generally set to be uniform in specification for convenience in management, inventory check and production and manufacturing cost saving in a production workshop, so that the conventional alloy bearing devices are difficult to adapt to sintering of hard alloy parisons with various sizes.
