High-quality and energy-saving gear-grinding jig saw and production process thereof

Abstract

The invention discloses a high-quality and energy-saving gear-grinding jig saw and a production process thereof, relating to the technical field of gear-grinding jig saws for cutting plates, in particular to an aspect of reducing the production cost on the premise of not reducing the quality. The problem of high production material cost of materials of the jig saw is solved. The high-quality and energy-saving gear-grinding jig saw comprises a main body and is characterized in that the main body comprises a saw back part made of a high-carbon steel (HCS) material and a saw teeth part made of a high-speed steel (HSS) material, wherein the saw back part made of the HCS material and the saw teeth part made of the HSS material are welded in an electron beam welding manner. The HCS material is used to replace the material of the saw back part of the traditional jig saw and is welded together with the saw teeth part made of the HSS material in the electron beam welding manner, so that the production cost is effectively saved. Due to the unique shape of the jig saw disclosed by the invention, the resistance is low when the jig saw is used, and the jig saw has the advantages of increased cutting speed and prolonged service life.

Description

technical field [0001] The invention relates to the technical field of a tooth-grinding curve saw for cutting boards, in particular to reducing production costs without reducing quality. Background technique [0002] At present, the jigsaws on the market are all made of HSS material (high-speed steel), and the HSS material on the back is not used for cutting, which is a waste of material; although the HSS material can still maintain high hardness and durability under high heat conditions (about 500°C), However, the heat treatment process of HSS materials is more complicated, and the production cost is significantly higher than that of HCS materials (high carbon steel). Although HCS materials are low in cost, they have poor wear resistance and are not suitable for direct use in the manufacture of jigsaws. Due to the high carbon content and poor thermal conductivity, it is not easy to weld, and there is a significant temperature difference between the welded area and the unhea...
