Abstract
The utility model relates to a quenching tank with an improved structure. The quenching tank with the improved structure comprises a quenching tank and is characterized in that a high-pressure gas pipe is arranged inside the lower part of the quenching tank, gas holes are uniformly distributed on the wall of the outer circle of the high-pressure gas pipe, and the high-pressure gas pipe is connected with an external high-pressure gas pipe valve by a pipeline; and a high-pressure water pipe is arranged inside one side of the quenching tank, water spray nozzles are uniformly distributed on the wall of the outer circle of the high-pressure water pipe, and the high-pressure water pipe is connected with an external high-pressure self-priming water pump by a pipeline. High-pressure gas and the high-pressure water pump form general circulation flow to quenching liquid, so that complete hardenability of a workpiece is improved and the phenomenon that a heat crack is caused on the local part of the workpiece as the quenching liquid stagnates is prevented. According to the quenching tank with the improved structure, the workpiece is quenched with circulated quenching liquid, so that tensile strength of the workpiece is improved by 10%, impact toughness of the workpiece is improved by 5%, and hardness HRC is improved by 10%.
Description
Technical field
The utility model relates to a kind of quenching bath, especially a kind of quenching bath of texture improvement.
Background technology
Traditional quenching technology is the hardening liquid of packing in quenching bath.Because hardening liquid remains static, can have following defective: 1. static quenching hardening capacity is poor, easily makes workpiece produce the quenching hot tearing under the state of Quench, causes workpiece to scrap; 2. mechanical property and the friction durability of quenching workpiece have been reduced.
Summary of the invention
The utility model provides a kind of quenching bath of texture improvement, and is simple in structure, improved mechanical property and the friction durability of quenching workpiece.
The technical solution of the utility model is: a kind of quenching bath of texture improvement, comprise quenching bath, it is characterized in that: high-pressure air pipe is built in the bottom of quenching bath, is evenly equipped with pore on the cylindrical wall of high-pressure air pipe, and high-pressure air pipe is connected with external high-pressure air pipe valve by pipeline; High-pressure water pipe is built in a side of quenching bath, is evenly equipped with water jet on the cylindrical wall of high-pressure water pipe, and high-pressure water pipe is connected with external high-pressure self-priming water pump by pipeline.
Further improvement to above-mentioned technical scheme is provided with expanded metal lath above described high-pressure air pipe.
Beneficial effect: before workpiece quenching, hardening liquid in quenching bath must be put in the scope of regulation, then open high pressured water circuling pump and opening high pressure tracheae valve, in the zone that stipulate the workpiece unloading in quenching furnance in the quenching bath this moment, because forming systemic circulation to hardening liquid, high pressure gas and high-pressure hydraulic pump flow in this zone, thereby improved the complete hardening capacity of workpiece, prevented the local phenomenon of hot tearing of stopping workpiece is caused because hardening liquid is stagnant.The utility model quenches to workpiece by the hardening liquid that circulates, and makes tensile strength raising 10%, impelling strength raising 5%, the hardness HRC of workpiece improve 10%.
