Abstract

The invention provides a welding and gas quenching integrated furnace for a lengthened cutter, and belongs to the technical field of equipment manufacturing. The problem that an existing lengthened cutter is short in service life is solved. The welding and gas quenching integrated furnace for the lengthened cutter comprises a welding bin, a gas quenching bin and a conveying device. The conveying device penetrates through the welding bin and the gas quenching bin, and a vacuum isolation device is arranged between the welding bin and the gas quenching bin. A carburization control system and a temperature sensor are arranged in the welding bin, the carburization control system is used for controlling the carbon potential of the lengthened cutter in the welding process of the lengthened cutter, and the temperature sensor detects the temperature of the lengthened cutter in the welding process of the lengthened cutter. When welding is finished and the temperature of the lengthened cutter is within the preset range, the conveying device is started, and the lengthened cutter is conveyed to the gas quenching bin through the vacuum isolation device. A nitrogen spraying device is arranged in the gas quenching bin and used for spraying nitrogen, and gas quenching is conducted on the lengthened cutter.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to an integrated welding and gas quenching furnace for extended cutters. Background technique [0002] With the rapid development of the equipment manufacturing industry, the demand for tool specifications and types is also more diverse. For example, extended knives of more than two meters also require higher quality. Limited by welding and heat treatment technology, the service life of extended tools is usually relatively short. [0003] The traditional knife production process is to assemble the blade, brazing filler metal and cutter body, put them into the coke furnace for heating and welding, and take out the cutter from the coke furnace after the brazing filler metal is melted visually, and press it on the press machine. The knife body is compacted and shaped, and then placed under an electric fan to cool down to achieve the purpose of heat treatment. This ap...
