Abstract
A heat treatment device for steel wheel products includes a frame equipped with a spraying circle and a water pipe joint at the top; the water pipe joint connects the water source; the workpiece of heat treatment steel wheel products is placed in the frame, the cove side of which faces the spraying circle. The utility model is characterized in that the spraying time can be controlled by adjusting the residue heat and the hardness and depth of quenching can be regulated within limits by controlling the residual heat, which does not require the complicated and expensive treatment equipment and auxiliary equipments or tempering in the furnace once again, obvious energy saving, easy and convenient operation; in addition, the utility model can reduce two processing procedures, thereby reducing production costs.
Description
Technical field
The utility model relates to the steel wheel series products as fortune ore deposit dolly wheel, the thermal treatment unit of driving wheel etc.
Background technology
The performance characteristics of steel wheel class spare part has determined its face of spoiling of taking turns that higher wear resistance must be arranged, and requires its surperficial hardness about HRc45, and hardened layer also must not be too shallow, and the general degree of depth requires more than 5mm.Convenient for guaranteeing operating safety and precision work, require the intensity height of its matrix, the plasticity good toughness, so adopt medium carbon structure steel casting or forging usually, its metalworking complex process,---modified---semi-finishing---wheel is spoilt face thermal treatment (intermediate frequency or power frequency heat hardening add tempering)---precision work that flow process is: roughing.
Summary of the invention
The purpose of this utility model just provides a kind ofly can make that manufacturing procedure is simple, heat treatment operation is convenient, energy consumption is low, the thermal treatment unit of the steel wheel series products that can reduce production costs.
The thermal treatment unit of steel wheel series products of the present utility model comprises frame, and the end of frame is provided with water spray ring and water pipe head, and water pipe head and water source join, and heat treated steel wheel series products workpiece is placed in the frame, and workpiece is spoilt face and faced water spray ring.
The heat treating method of steel wheel series products of the present utility model is to whole workpiece heating, spoils the face spray quenching, and its Heating temperature, soaking time are identical with common process.The part that water spray only hardens to need during quenching is cooled off fast, the heat of this part of taking, other parts of workpiece also have a large amount of heats, when hardened depth is enough, stop water spray, these heats will be slowly to the part diffusion of hardening, partly play the tempered effect to hardening, its metallographic structure is: " tempering troostite ", the speed of cooling of rest part are greater than air cooling, and the metallographic structure that obtains is: " normalizing sorbite ".
The thermal treatment unit characteristics of steel wheel series products of the present utility model are that the control water spraying time is regulated surplus heat, just can regulate the quenching hardness and the degree of depth by the control surplus heat in certain limit, it makes thermal treatment process not need complicated, valuable Equipment for Heating Processing and utility appliance, do not need to advance once more the stove tempering, energy-conservation obvious, simple to operation, and can reduce by two manufacturing procedures, thus reduce production costs.
Description of drawings
Fig. 1 is the utility model structural representation.
