Problems solved by technology

Equipment is expensive, and welding quality is easily affected by equipment stability and raw material quality
[0006] 2. During the welding process, the weld position is continuously heated, and the heat-affected zone of the weld position is large, which is prone to some undesirable deformations;
During processing, most of the high-speed steel is removed as chips, resulting in a lot of waste of high-speed steel

Embodiment Construction

[0027] A method for processing a bimetallic band saw blade is characterized in that it comprises the following steps:

[0028] 1) Process the band saw blade body 1, and process a plurality of arcs on the welding surface at the top of the band saw blade body along the length direction of the band saw blade body 1;

[0029] 2) Preset a high-speed steel particle 2 on each welding surface arc of the band saw blade body 1, and the welding surface arc radius R 1 with a spherical HSS particle radius R 2 The relationship between is: R 2 ≤R 1 ≤R 2 +0.5;

[0030] The center O of the arc of the welding surface of the band saw blade body 1 1 Placed on the band saw blade body 1 below the line BG between the front and rear blade faces and close to the rake face, and O 1 The distance a from BG in the length direction of the band saw blade 1 Meet: 0.1R 2 ≤a 1 ≤0.3R 2 ;

[0031] o 1 The distance a from BG in the width direction of the band saw blade 2 Meet: 0.5R 2 ≤a 2 ≤0.8R...

Abstract

The invention relates to a method for machining a double-metal band saw blade. The method includes the steps that a high-speed steel particle is preset on each weld face arc of a band saw blade body, and the relation between the weld face arc radius R1 and the high-speed steel particle radius R2 is that R2<=R1<=R2+0.5. According to the method for machining the double-metal band saw blade, waste of high-speed steel material in the saw tooth forming process of traditional double metal is avoided, arc lines are adopted for weld faces in use, the length of weld seams is larger than that of a traditional double metal saw blade, and the weld face arcs and the high-speed steel particles are arranged in space positions, so that the saw blade body can generate a base support effect, saw tooth cutting force is transmitted to the saw blade body more easily, and the saw blade bears larger cutting force. The diameter of the weld face arcs is larger than that of the high-speed particles, and when compressive deformation is generated, the bonding of the weld faces is more reliable.

Description

technical field [0001] The invention relates to a method for processing bimetallic band saw blades. Background technique [0002] As the main method of metal cutting, band saw cutting has been widely used in various industries of metal processing. In terms of materials, the commonly used band saw blades for metal cutting are made of high-speed steel or cemented carbide for the cutting edge of the teeth, and alloy steel with high strength, good toughness and excellent fatigue performance is used for the body part, which is the so-called double blade. Metal band saw blade. The commonly used manufacturing method of bimetallic band saw blades usually adopts high-energy welding technology to compound the back material steel strip and the tooth material steel wire, then milling and forming, and then process it through processes such as tooth division and heat treatment. [0003] At present, there are few reports on the method of welding the back material with teeth particles, an...
