Description
Technical field
The utility model belongs to technical field of heat treatment, relates generally to the laser heating process of longaxones parts.
Background technology
At present, as the longaxones parts such as the gear-shift shaft that the compact internal combustion engine such as motorcycle uses need to carry out to quench, tempering heat treatment, such as steel quenching time need to be heated to critical temperature Ac3(hypoeutectoid steel) or Ac1(hypereutectoid steel) more than a certain temperature, interior tissue carries out austenitic abundant transformation.The quenching temperature of different steel is not identical, quenching part generally to reach 850 DEG C ~ 930 DEG C, quenching needs the time of more than 30MIN.When tempering again from quenching temperature quick refrigeration to self tempering temperature (about 160 DEG C ~ 250 DEG C), just there is the phenomenon of expanding with heat and contract with cold.The size of linear (axis) also can be thereupon elongated and shorten along with the rising of temperature and reduction.So the size of part when thermoforming will increase corresponding swell increment on final size, after waiting quenching to shrink, obtain final size.Quenching, the whole process of tempering at least need the time of more than 3 hours, and quenching strain is also comparatively large, because the complete period needs more than 3.5 hours.
Processing longaxones parts thermoforming quenching at present, tempering process realize on different devices both at home and abroad, namely on an equipment, thermoforming is carried out, and on an other equipment, carry out integral quenching, namely workpiece needs a dead lift to tempering equipment through heating after cooling settings, so just cause efficiency low, the production management problems such as easy batch mixing.
Utility model content
The heat-treatment production line that the utility model is intended to provide a kind of Continuous maching, reduces manpower.
Heat-treatment production line in this programme, comprises mechanical feed, heating installation, quenching apparatus and tempering stove that the outlet of mechanical feed connects successively, and heating installation comprises process furnace, and the outlet of this process furnace is connected with quenching apparatus by automatic transmission chain; Quenching apparatus comprises quenching chamber, and this quenching chamber is connected by pipeline with hardening liquid packing groove; The outlet of quenching chamber is connected with tempering stove by automatic transmission chain.
The beneficial effects of the utility model are: workpiece enters heating installation through mechanical feed, the workpiece completing austenitizing after diathermanous is sent to quenching chamber through automatic transmission chain and quenches, because quenching chamber is connected with hardening liquid packing groove, the circulation of hardening liquid can be realized, improve the effect of quenching, workpiece after quenching is delivered in tempering stove through automatic transmission chain, carries out tempering.The utility model structure is simple, can realize workpiece heat, the carrying out continuously of Quench and temper, and the efficiency of processing is high and batch mixing is less likely to occur.
Further, be provided with interior cooling tank in described quenching chamber, this interior cooling tank is connected with hardening liquid packing groove by hardening liquid dispatch tube, hardening liquid recovery tube, and described hardening liquid dispatch tube, hardening liquid recovery tube are equipped with water pump.The workpiece completing austenitizing after diathermanous is sent to interior cooling tank by automatic transmission chain, and realize quick Cooling Quenching in transmission, cooling fluid circulates between interior cooling tank and hardening liquid packing groove, and cooling performance is even, is conducive to Reducing distortion amount.
Further, hardening liquid packing groove is connected by pipeline with hardening liquid cooling tower, and circulate between cooling tank and hardening liquid packing groove, cooling tower in cooling fluid, cooling performance is better.
Further, tempering stove is net belt type tempering stove, tempering better effects if.
Further, interior cooling tank is provided with temperature control system, the temperature in monitoring in cooling tank, thus the hardening liquid output speed controlling water pump.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model heat-treatment production line embodiment.
Embodiment
Reference numeral in Figure of description 1 comprises: mechanical feed 1, intermediate-frequency heating furnace 2, quenching chamber 3, tempering stove 4, hardening liquid packing groove 5, hardening liquid cooling tower 6, automatic transmission chain 7, hardening liquid dispatch tube 8, hardening liquid recovery tube 9, workpiece 10.
As shown in Figure 1: the invention provides a kind of heat-treatment production line, mechanical feed 1, intermediate-frequency heating furnace 2, quenching chamber 3, tempering stove 4 and hardening liquid packing groove 5, hardening liquid cooling tower 6 is comprised.
Intermediate-frequency heating furnace, quenching chamber and tempering stove that the outlet of mechanical feed connects successively, mechanical feed, intermediate-frequency heating furnace, quenching chamber are connected with tempering stove by automatic transmission chain 7, and workpiece 10 is placed on automatic transmission chain successively through techniques such as heating, Quench and temper.
Ruhmkorff coil mechanism being installed in intermediate-frequency heating furnace, when passing into the exchange current of certain frequency in ruhmkorff coil, namely producing alternating magnetic field around.The electromagnetic induction effect of alternating magnetic field makes to produce closed induced current and eddy current in workpiece.Induced current is very high in workpiece surface current density, inwardly reduce gradually, the converting electric energy of workpiece surface high-density current is heat energy, the temperature on top layer is raised, after reaching loss of excitation point, the penetration depth of eddy current will enlarge markedly, and eddy current penetration depth is now than much larger times of thin layer eddy current penetration depth before loss of excitation point.This eddy current continuous internally " infiltration " heats workpiece, and the upper layer of workpiece also can not be overheated, can realize quick diathermanous heating, reaches the austenitizing requirement needed for workpiece.
In quenching chamber, be provided with interior cooling tank, automatic transmission chain runs through this interior cooling tank.Hardening liquid packing groove and hardening liquid cooling tower is had outside quenching chamber, interior cooling tank is first connected with hardening liquid packing groove by hardening liquid dispatch tube 8, be connected with hardening liquid cooling tower again, hardening liquid dispatch tube is provided with water pump, hardening liquid in interior cooling tank can be made first through hardening liquid packing groove, then enter in hardening liquid cooling tower.Hardening liquid cooling tower is first connected with hardening liquid packing groove by hardening liquid recovery tube 9, be connected with interior cooling tank again, hardening liquid recovery tube is provided with water pump, and the hardening liquid in hardening liquid cooling tower is back in interior cooling tank through hardening liquid packing groove, and in realizing, cooling tank circulates.The outlet of interior cooling tank carries out tempering by automatic transmission chain by workpiece transfer to tempering stove.
The present embodiment is completely in induction diathermanous and cooling fast automatically fast, shorten heat treatment cycle, Quench heating completes to cooling only need less than 10MIN, add tempering 2.5 hours, full heat treatment cycle shortens more than prior heat treatment line, efficiency improves, and because the good uniformity of rapid heating and cooling fast, so thermal treatment after strain amount is less than prior heat treatment line.
The foregoing is only the detailed description of the utility model preferred embodiment, be not used for limiting the utility model, all embodiments complying with the similar change that creation spirit of the present utility model is done, all should be contained among the utility model protection domain.
