Embodiment 1

[0025] Example one, please refer to figure 1 In this embodiment, a high-strength saw blade production process includes the following steps:

[0026] S1. Material selection: M42 high-speed steel is selected for sawtooth material, and X32 spring steel is selected for saw back material;

[0027] S2. Preliminary processing: The processing steps are cutting, welding, annealing, straightening and milling. According to the size of the saw blade produced, when cutting M42 high-speed steel and X32 spring steel, the cutting is carried out by a wire cutting machine. When the material is not deformed by force, and under the control of CNC commands, the machining accuracy is high, the cutting seam is narrow, and the material utilization rate is high; then the cut M42 high-speed steel and X32 spring steel are welded together, and the welding is high-frequency induction brazing Technology for welding, which uses the principle of induction heating to heat M42 high-speed steel and X32 spring steel...

Abstract

The invention discloses a high-strength saw blade production technology. The high-strength saw blade production technology sequentially comprises the steps of material selecting, primary processing, heat treatment and surface finishing. Surface finishing comprises the step of sand blasting treatment, specifically, a dry blasting technology is adopted for sand blasting treatment, after sand blasting treatment, smooth tooth tips are formed, grinding is not needed in the sawing process, and the tooth breakage probability of tooth parts is decreased; impact force of cutting and vibrating can be borne, uniform force bearing of a cutting tool is ensured, and the cutting life of the tooth parts of the cutting tool is prolonged; and after sand blasting, the fatigue life of a backing material is prolonged, the fatigue performance of the back of a saw blade in the working condition of cutting ordinary carbon steel is greatly exerted, and the service life of the saw blade is prolonged.

Description

Technical field [0001] The invention relates to the field of waste water disposal devices, in particular to a high-strength saw blade production process. Background technique [0002] The bimetal band saw blade is a sawing tool made of high-speed steel (tooth) and spring steel strip (back) through electron beam welding or laser welding, and then through a series of cold and hot processing processes. It has high efficiency, energy saving, and energy saving. The characteristics of materials are widely used in the machinery industry. During the sawing process, the bimetal band saw blade is subjected to periodic tensile stress, intermittent impact force and torsion force. The main failure modes are back fatigue fracture and tooth wear, so the fatigue strength of the back and the strong tooth Toughness is an important indicator of the overall performance of the saw blade. The existing saw blade production process cannot maximize the strength and toughness of the tooth material and t...
