Abstract

The invention provides quenching equipment for a chain hinge pin with high static load bending strength, and belongs to the technical field of hinge pin thermal treatment equipment. The quenching equipment for the chain hinge pin with the high static load bending strength comprises a treatment box body, a connecting pipeline, an oil storage tank, a water storage tank and a servo motor, a fixed disc is arranged in the interior of the treatment box body, a communicating opening is formed in the interior of the fixed disc, and the communicating opening is in a vertical linear shape. The equipment can accurately control the time point of double-liquid conversion, then the internal stress of martensite conversion of the hinge pin can be effectively reduced, the tendency of deformation and cracking of a workpiece is reduced, the structural performance of the workpiece is optimized, used water and oil can be well classified and collected, and meanwhile, the production efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of heat treatment equipment for pin shafts, in particular to quenching equipment for chain pin shafts with high static load bending strength. Background technique [0002] The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), keep it warm for a period of time to make it fully or partially austenitized, and then cool it at a temperature greater than the critical cooling rate. The heat treatment process of rapid and rapid cooling to below Ms (or isothermal near Ms) for martensite (or bainite) transformation. Usually, the solid solution treatment of aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials or the heat treatment process with rapid cooling process is called quenching. [0003] In the traditional quenching method, there is rarely dual-medium quenching, because the disadvantage of ...
