Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the production process of the saw blade is to weld the hard alloy particles one by one to the outer periphery of the saw blade body through flame surfacing welding. Since the dimensional accuracy of the flame surfacing welding is uncontrollable, the surfacing welding efficiency is relatively low. In addition, due to the low efficiency of this method, generally only cemented carbide particles of the same size and particle size are welded during flame surfacing, so the gap between two adjacent cemented carbide particles is relatively possible Larger, resulting in poor compactness of the working part of the entire saw blade, affecting product quality and service life, and a high-efficiency multi-layer brazed diamond saw blade production process is proposed

Abstract

The invention discloses a production process of an efficient multi-layer brazed diamond saw blade. The production process comprises the following steps that raw materials of abrasive blocks are added into a stainless steel reaction kettle to be mixed for 2 hours; a plurality of sets of conical holes are evenly formed in a base plate, then the mixed abrasive blocks are poured into the conical holes in the base plate and stricken to be flat, then the base plate is put into an oven to be baked, and after baking is finished, the base plate is taken out and cooled at the room temperature; and the side wall of the saw blade base body is coated with an adhesive layer, then a conical abrasive block is fixed to the surface of the saw blade base body through an upper abrasive block device, brazing is conducted, and the efficient multi-layer brazing diamond saw blade is obtained. According to the production process, the layer-brazed diamond saw blade is prepared through the processes of abrasive block preparing, abrasive block forming, abrasive block feeding and braze welding on the diamond saw blade; and the abrasive blocks in the saw blade are distributed on the saw blade base body in a multi-layer mode, so that the efficient multi-layer brazed diamond saw blade body has high strength and long service life in the using process.

Description

technical field [0001] The invention belongs to the technical field of saw blades, in particular to a production process of high-efficiency multi-layer brazing diamond saw blades. Background technique [0002] A saw blade is a general term for thin, circular knives used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting; high-speed steel saw blades for metal material cutting (not inlaid with carbide blades); for solid wood, furniture, wood-based panels, aluminum alloys, aluminum profiles Carbide saw blades for cutting radiators, plastics, plastic steel, etc. [0003] In the prior art, the production process of the saw blade is to weld the hard alloy particles one by one to the outer periphery of the saw blade body through flame surfacing welding. Since the dimensional accuracy of the flame surfacing welding is uncontrollable, the surfacing welding efficiency is low. In addition, Due to the low efficiency of this method, generally o...
