A bearing device for preventing diamond saw blades from sticking to each other

Abstract

The invention relates to a carrying device for avoiding the mutual bonding of diamond saw blades, which includes a supporting column and a limiting column fixedly arranged on the upper end of the supporting column. Rotating connecting frame, the outside of the connecting frame has a plurality of saw blade supporting structures distributed in equal circles, and the saw blade supporting structure includes a plurality of saw blade supporting assemblies distributed sequentially from top to bottom and synchronously driving a plurality of saw blade supporting assemblies to swing Drive assembly, a plurality of drive assemblies and a plurality of zigzagging runners are arranged correspondingly in sequence, and the plurality of saw blade support structures slide along the zigzag flow passages with the rotation of the connecting frame, thereby driving multiple blade support structures on each saw blade support structure. The two saw blade support components perform circular rotation and circumferential swing synchronously. The invention has the following advantages: effectively avoiding the mutual bonding of the diamond saw blades during the sintering process, ensuring the heating uniformity of each diamond saw blade, and improving the mechanical properties of the diamond saw blades.

Description

technical field [0001] The invention belongs to the field of diamond saw blade sintering, and in particular relates to a bearing device for avoiding mutual bonding of diamond saw blades. Background technique [0002] Diamond saw blade is a cutting tool, which is widely used in the processing of hard and brittle materials such as stone, concrete, prefabricated panels, ceramics, and new roads. In order to ensure the structural strength and cutting hardness of the diamond cutter head, the metal powder containing diamond powder is usually mixed uniformly and then pressed on the outer circumference of the substrate to form a diamond compact, and then sintered to form a diamond saw blade. [0003] The process of diamond compact sintering is the process of bonding between mixed metal particles in the compact. During sintering, the mixed metal particles undergo gas desorption, surface atom rearrangement, desorption of chemically adsorbed surface compounds, and internal recrystalliza...

AI Technical Summary

Problems solved by technology

[0003] The sintering process of diamond compacts is the process of bonding between mixed metal particles in the compact. During sintering, mixed metal particles undergo gas desorption, rearrangement of surface atoms, desorption of chemically adsorbed surface compounds, and internal recrystallization of metal particles. Therefore, when multiple diamond compacts are sintered, in order to prevent adjacent diamond compacts from contacting each other and causing sticking after sintering, multiple diamond compacts and graphite gaskets are usually arranged vertically at intervals. In the rod body of the sintering chamber, the contact surface between the diamond compact and the graphite gasket is relatively large. During sintering, the contact position between the diamond compact and the graphite gasket is blocked, and high-quality sintering cannot be achieved, and the diamond saw blade cannot be guaranteed. The uniformity of heating, so that the mechanical properties such as the structural strength of the diamond saw blade cannot be guaranteed
