Abstract

The invention discloses a wear-resisting screw reamer. The wear-resisting screw reamer is characterized in that a material collecting segment, a conveying segment and an extrusion segment are included; the material collecting segment, the conveying segment and the extrusion segment are sequentially connected from top to bottom; screw blades are arranged on the material collecting segment, the conveying segment and the extrusion segment; and the screw blades are fixedly connected with a center shaft through electric welding. The wear-resisting screw reamer has the advantages that the work angle and width of the screw blades are improved, so that the work efficiency of the screw reamer is improved, and production is accelerated; and meanwhile, wear-resisting layers are arranged on the surfaces of the screw blades, so that the service life of the screw blades is prolonged, and the use rate of the screw blades is increased.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a wear-resistant spiral reamer. Background technique [0002] A reamer is a rotating tool with one or more teeth used to remove a thin layer of metal from the machined surface of a hole. The reamed hole can obtain precise size and shape after reaming. The reamer is used to ream the drilled (or reamed) hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce its surface roughness. It is a tool for finishing and semi-finishing the hole , The machining allowance is generally very small. Reamers used to process cylindrical holes are more commonly used. The reamer used to process tapered holes is a tapered reamer, which is relatively rare. According to the use situation, there are hand reamers and machine reamers, and machine reamers can be divided into straight shank reamers and tapered shank reamers. Hands are of straight handle type. [0003] The sp...
