Abstract
The invention provides a push rod-type continuous vacuum tempering and annealing multipurpose furnace, which is an annealing and tempering equipment used in the heat treatment industry and is a continuous annealing and tempering equipment. All existing tempering furnaces adopt a single-way and single-room working mode. A workpiece that is heated cannot be taken out until an entire heating room is cooled and the heating room needs to be reheated for a second tempering, resulting in a waste of energy. In addition to incontinuous working, and the tempering process time is more than twice the quenching time, therefore the production efficiency of the existing vacuum tempering furnace is too low to meet the high-volume production needs. The invention provides the annealing and tempering furnace which can achieve continuous working and is characterized in that: the overall operation adopts a raceway-type push rod structure, the furnace comprises a vacuumized feeding transfer room, a heating room, a rapid air-cooled room and a discharging transfer room, and is divided into four parts, wherein each part not only can be vacuumized at the same time but also can be vacuumized separately. The whole operating process can fully realize automation through PLC except for material feeding and discharging.
Description
Invention field:
The present invention is a kind of annealing and the tempering equipment of heat treatment industry, is a kind of annealing tempering equipment of continous way.
Background technology:
Present tempering stove all adopts the mode of single single chamber operation. after the workpiece heating finishes, need and workpiece can be taken out after the whole heating chamber cooling, heating chamber needs to restart heating again when second time tempering, wasted the energy. owing to do not work continuously, add that the tempering process time is more than the twice of cool time, so under vacuum tempering furnace production is originally renderd a service, do not have the requirements of large-scale production of adaptation.
Summary of the invention:
The present invention is a kind of temper annealing stove of working continuously realized, its overall operation adopts the rollaway type pusher structure, vacuumize the charging transfer chamber, the heating zone, compositions such as quick air-cooled district and discharging transfer chamber, integral body is divided into four parts, and each several part not only can vacuumize simultaneously but also can independently vacuumize separately. and the entire operation process can realize automatization by PLC fully except that charging and discharging.
Specific implementation method:
One-piece construction is made up of four parts, there is hydraulic ram the charging transfer chamber, the side door feeding gate, push rod, raceway, preceding slide valve insulated door is formed. and the transfer chamber need not be oversize, moving back bar can directly once push heating chamber with workpiece and get final product. and heating chamber has raceway, heating unit, the thermal convection blower fan, it is longer that back slide valve insulated door is formed entire structure, specifically can determine according to the time of need heating and the size of workpiece. and quick air-cooled district is by fast cold blast engine, interchanger, composition such as feed mechanism and flashboard valve. the discharging transfer chamber is made up of raceway and flashboard valve. and whole body of heater can adopt circular or square double-walled water-cooled, and pumped vacuum systems can be made up of two cover vacuum units, not only can vacuumize simultaneously but also can independently vacuumize separately in four Room. all mechanical actions, temperature controls etc. are controlled automatically by PLC, easy to operate high efficiency.
Claims (2)
1. with raceway and push rod workpiece is transported to each chamber and realizes tempering or annealed purpose.
2. entire structure is made up of main four parts: charging transfer chamber heating discharging transfer chamber, the quick air-cooled district of refined zone.
