By utilizing the residual heat after forging, the high temperature quenching and forging are combined to form a continuous production line organicly, therefor the utility model has the advantage of enery saving, less land occupation, fewer time in heat treatment producing, high production efficiency, lower production cost, reducing the radiation pollution to the workshop environment, better heat treatment quality.
Description
Technical field
The utility model relates to a kind of novel thermal process device of spindle, belongs to the Equipment for Heating Processing technical field.
Background technology
Spindle common used material 40Cr or 40MnB, conventional modified process of thermal treatment is: will forge postcooling and be heated to 850 ℃ quenching temperature to the steering knuckle of room temperature, begin to heat and time of being incubated is 2h from normal temperature, going into quenching tank after the heat quenches, reinstall tempering in the tempering stove, 560 ℃ of tempering temperatures, tempering heating and soaking time 2-5h.Many quenching process furnace, casting chain slab furnace or multipurpose furnace production line are adopted in conventional modifier treatment, and investment is big, production efficiency is low; Be heated to quenching temperature from room temperature again after the forging cooling, power consumption is big, occupation of land is big, pollute workshop condition; And do not have equal Hot-air fan when 1050 ℃ of process furnace heating, the workpiece heating is inhomogeneous, and the crystal grain thinning after forging is grown up, and modified back hardness is inhomogeneous, and metallographic does not reach requirement, makes the heat treatment of workpieces quality very unstable.
Chinese patent ZL03269188.2 has disclosed a kind of device that utilizes the forging waste heat to heat-treat, by vibration feeding machine forging is sent on the intravital chain type conveying belt of stove, heating unit carries out heat tracing to the forging that has waste heat, by the chain type conveying belt forging is sent into dichotomous discharge bucket again.But this device uses through process furnace of long strip shape and rectangle quenching tank, and the quenchant cooling system is placed on indoor, and floor space is big; Used the chain type conveying belt in the through process furnace, every one week of circulation of chain type conveying belt, can be in vain behind the bottom of coming out of the stove fall the most of calorific loss of conveying belt, also need reheat after entering fire door again; And can not be adapted to the equal heat request of steering knuckle of different shapes, size.
Summary of the invention
The utility model is at the deficiency of heat quenching technology in conventional modified thermal treatment of existing spindle and the ZL03269188.2 Patent equipment, and a kind of high temperature soaking quenching heat treatment device that the spindle forging is reheated of not needing is provided.This device with quench hot with forge organically form tinuous production, the treatment production time is short, production efficiency is high, take up an area of less, more energy-conservation, reduce production costs, thermal treatment quality is good.
The utility model is achieved through the following technical measures.
This device mainly comprises: the slideway that is connected with clipping press, the slideway the other end connects stepless speed regulation revolving ring type soaking pit, soaking temperature by temperature control unit control soaking pit, the revolving ring type soaking pit is provided with the discharging slideway, the discharging slideway connects quenching tank, quenchant in the quenching tank adopts the outdoor recycle system to recycle, and stepless speed regulation chain-plate type lift is installed in the quenching tank, and the workpiece after lift will quench is lifted out quenching tank and sends into charging basket.
Described stepless speed regulation revolving ring type soaking pit mainly is made up of revolving ring type body of heater, stepless speed regulation transmission rig and temperature control unit.The effect of revolving ring type soaking pit mainly is after the forging more than 900 ℃ rotates a week with stove in addition with the back of cutting edge, all to reach 850 ℃ quenching temperature equably.Its furnace bottom heating intensity should be consistent with the forging productive temp with velocity of rotation, can guarantee consistent quenching temperature again.The furnace bottom heating intensity guarantees that by furnace bottom change area and heating unit velocity of rotation is guaranteed by stageless transmission mechanism.According to the size of steering knuckle forging, in stove, rotate a week as long as 12-15 minute.Big steering knuckle is adorned fewly, and little steering knuckle is adorned manyly, so the adjusting of temperature control unit is very easily.
The outdoor recycle system of described quenchant mainly is made up of quenching tank, quenchant and the outdoor recycle system.Quenching tank is made drum, interior dress quenchant, have the quenchant cooling tank in the outside, workshop, link to each other with indoor quenching tank with pipeline by pump, take the quenchant of heat to outdoor media slot, by pump cooled quenchant is delivered to indoor quenching tank, guarantee quenching needed medium temperature, thereby guaranteed the quenching technology requirement of workpiece.
Described stepless speed regulation chain-plate type lift is to drive the chain-plate type lift by stepless speed-regulating motor the quenching workpiece is come out by lifting in the quenching tank.Its design feature is the size according to the steering knuckle forging, all can guarantee the cool time of workpiece in quenchant.And this cool time requirement is consistent with the beat of converter and forging production.
Compared with prior art, the utlity model has following advantage:
1. adopted circular pit and circular quenching tank, the quenchant cooling system is placed on outdoor, has saved factory building widely and has produced area.
2. adopted the revolving ring type soaking pit, furnace bottom turns round in burner hearth all the time, and any heat can not scatter and disappear.
3. change stove and quenching lift having been adopted stepless speed regulation, not only organically cooperated the soaking time requirement of forging the beat of producing but also having satisfied different steering knuckles, is the thermal treatment unit of a flexibility.
Adopt the utility model, the soaking time of soaking heat treatment technique only is 0.3 hour, and be 3 hours quenching heat-up time of conventional thermal treatment process, therefore saved the energy greatly, improved production efficiency.
