Description
Technical field
The utility model relates to a kind of thermal treatment cooling apparatus, and particularly a kind of pre-treatment production line is with air-cooled.
Background technology
Air-cooled is one of type of cooling commonly used in the thermal treatment field.Often needing to adopt air blast cooling after some heat treatment of workpieces, is arts demand on the one hand, as the workpiece normalizing, often adopts air blast cooling to obtain comparatively ideal effect after the heating; On the other hand, adopt air blast cooling can under lower cost, can obtain evenly and fast cooling, as adopting air blast cooling after the workpiece tempering, not only make cooling more even, and accelerated speed of cooling, shortened process cycle.
Be example with the normalizing, there is following several respects problem in the traditional air cooling way after the heat treatment of workpieces more at present:
(1) workpiece is placed on the chassis or on the frock, adopts the powerful fan blowing to cool off around, and this not only can cause single work-piece cools inequality and produce very big stress, and the generation of stress will cause the probability of workpiece cracking, distortion to increase; And work-piece cools is inhomogeneous also can produce very big difference of hardness, is unfavorable for follow-up machining, also can cause the irregular deformation of the final thermal treatment of workpiece (as carburizing and quenching).And the workpiece hardness scattered error with batch processed is big, and different workpieces performance inequality causes follow-up machining difficulty to increase, and final thermal treatment (as carburizing and quenching) distortion is irregular.Simultaneously, because the high temperature workpiece is exposed to the workshop, human body is produced thermal radiation, also causes the workshop temperature to raise, severe exacerbation workman's Working environment.
(2) workpiece after will heating is hung oneself out from chassis or frock, bulk storage on the ground, or workpiece is placed on the easy cooling table, around with fan blowing cooling, though this mode has been improved the problem of work-piece cools inequality to a certain extent, but this mode still can cause a large amount of heat energy dissipations in the workshop, not only wastes energy but also worsens environment.
(3) the existing type of cooling, can not accurately control work-piece cools temperature and speed of cooling, need control the workpiece of cooling temperature for some, as workpiece is carried out isothermal normalizing, be that the workpiece heating is cooled off fast, carry out isothermal when being cooled to perlitic transformation district (between 600-650 ℃), treat that structural transformation fully after, carry out air cooling or air-cooled again.This workpiece pretreatment technology adopts the above-mentioned type of cooling to be difficult to realize, often needs specific equipment-isothermal normalizing production line, and this needs a very big investment, is unfavorable for the large-scale promotion utilization.
