Abstract
The invention provides an oil-quenching and air-quenching continuous vacuum furnace, including a feed space, a heating space and a discharge space, and the three spaces are provided in one furnace chamber. The furnace chamber is further divided into an air-quenching space, a heating space and an oil-quenching discharge space, and the three spaces co-use a set of big-power vacuum pumps. Encapsulated governor valves are provided when connecting the pipes, selectively in vacuum-pumping condition. In this way, when the parts are quenched in oil after heating, the feed space begins to charge and pump vacuum. Therefore, the heating space needn't reduce temperature which saves time.
Description
Technical field
The present invention relates to a kind of vacuum oven, especially oil-quenching gas-quenching continuous vacuum furnace.
Background technology
After each oil quenching of double-chamber vacuum oil-quenching air-cooling stove two Room of China finishes at present, wait until that workpiece temperature is reduced in the certain limit, just can open fire door,, heat again in case oxidation when making second batch of workpiece again, be evacuated down to technological standards again.The time and the energy have been wasted like this, inefficiency, cost height.Because gas is quenched and the grease chamber is same chamber, so the air cooling effect is bad, is subject to the pollution of oil gas.
Summary of the invention
Task of the present invention provides a kind of energy-conservation oil-quenching gas-quenching continuous vacuum furnace.
For achieving the above object, the scheme that is adopted is:
A kind of oil-quenching gas-quenching continuous vacuum furnace, comprise feed chamber, heating chamber, discharge chamber, it is characterized in that the merging of three Room is arranged in the furnace chamber, furnace chamber inside is respectively gas quench chamber, heating chamber, oil quenching discharge chamber again, the shared one group of high-power vacuum pump in three Room, when connecting tube, be added with sealed-regulating valve, optionally vacuumize.
Workpiece has heated the back when oil quenching like this, and feed chamber begins charging simultaneously and vacuumizes, and the heating chamber temperature need not to reduce, and has saved the time.
Embodiment
This novel three-eell furnace body is made up of quench chamber, heating chamber, oil quenching chamber, vacuum pump group of gas.All there is insulated door at the heating chamber two ends, and three pipelines of vacuum pump component lead to three Room, and sealed-regulating valve all is housed can selects to vacuumize.During first stove, workpiece is put into the gas chamber of quenching, push heating chamber then and put down charging basket, pull out truck, refill second charging basket locking fire door, insulated door is closed and is vacuumized and heat, after finishing, open oil quenching chamber door on one side earlier, truck also is housed in the oil quenching chamber, close the insulated door quench cooled after getting material, optionally the vacuum of cooling room is extracted into technological standards after getting material.The other side, second charging basket of little feed chamber selected for use push heating chamber heating automatically, fasten insulated door after taking out truck, open preceding fire door, reinstall the 3rd charging basket, vacuumize vacuum and reach technological standards, analogize in proper order, solved the expensive problem that vacuumizes and heat up and lower the temperature and bring because of waiting as long for.Can reach simultaneously the gas dual-purpose purpose of oil quenching of quenching.
Claims (3)
1. oil-quenching gas-quenching continuous vacuum furnace, comprise feed chamber, heating chamber, discharge chamber, it is characterized in that the merging of three Room is arranged in the furnace chamber, furnace chamber inside is respectively gas quench chamber, heating chamber, oil quenching discharge chamber again, the shared one group of high-power vacuum pump in three Room, when connecting tube, be added with sealed-regulating valve, optionally vacuumize.
2. according to claim 1, it is characterized in that the three-eell furnace body is made up of quench chamber, heating chamber, oil quenching chamber, vacuum pump group of gas.
3. according to claim 1, when it is characterized in that first stove, workpiece is put into the gas chamber of quenching, push heating chamber then and put down charging basket, pull out truck, refill second charging basket locking fire door, insulated door is closed and is vacuumized and heat, after finishing, open oil quenching chamber door on one side earlier, truck also is housed in the oil quenching chamber, closes the insulated door quench cooled after getting material, optionally the vacuum of cooling room is extracted into technological standards after getting material.The other side is selected second charging basket of little feed chamber for use to push heating chamber heating automatically, fastens insulated door after taking out truck, opens preceding fire door, reinstalls the 3rd charging basket, vacuumizes vacuum and reaches technological standards, analogizes in proper order.
