Problems solved by technology

[0002]At present, the production of high-speed steel pre-hardened materials is generally heated by ordinary salt bath furnaces. The disadvantage is that it is difficult to control the temperature, and the workpiece is easy to overheat or burn. The liquid surface causes the workpiece to form a wavy bend. The straightening machine used generally adopts the washboard type. For workpieces with a diameter of less than or equal to 4mm, the straightening effect of the workpiece is poor because the workpiece is not easy to roll, and some are not perpendicular to the transverse grain of the washboard. "Twist bends" are formed, and the straightening length is limited. Generally, the length is not more than 500mm. The longer the straightening effect is, the worse the straightening effect must be. Manual straightening is necessary. Many "wave bends" are formed during manual straightening. The tempering furnace used Due to the large amount of furnace loading and uneven furnace gas circulation, the tempering degree of each workpiece is inconsistent, resulting in uneven performance of the workpiece

Abstract

The invention discloses a device for producing a high-speed steel pre-hardening material. The device is formed by connecting a paying out reel, a first straightening machine, a quenching furnace, a quenching machine, a second straightening machine, a first tempering furnace, a first cooler, a third straightening machine, a second tempering furnace, a second cooler, a fourth straightening machine and a hauling and cutting machine in sequence, the sequential joint positions are connected by sealed channels. The invention has the characteristics that quenching, tempering, and straightening are combined to form a consecutive production line, a workpiece can be produced on line, the processing conditions of all parts in producing the workpiece are the same, and the quality of the workpiece is stable.

Description

technical field [0001] The invention belongs to the technical field of steel material deep processing equipment, and in particular relates to a high-speed steel pre-hardened material production device. Background technique [0002] At present, the production of high-speed steel pre-hardened materials is generally heated by ordinary salt bath furnaces. The disadvantage is that it is difficult to control the temperature, and the workpiece is easy to overheat or burn. When heating, the workpiece cannot be absolutely perpendicular to the liquid surface, causing the workpiece to form a wavy bend. The washboard type is adopted. For workpieces with a diameter of less than or equal to 4mm, the straightening effect of the workpiece is poor because the workpiece is not easy to roll. No more than 500mm. The longer the straightening effect is, the worse the straightening effect must be. Manual straightening is necessary. Many "wave bends" are formed during manual straightening. The deg...
