Abstract
The utility model discloses a vacuum sintering press vacuum chamber which comprises an upper and a lower meta-locked circular cover with water-cooling intermediate layer. The circular cover is provided with a doorway which has a door thereon. Due to the application of the above structure, this utility model has the following advantages: simple and rational structure of round vacuum chamber, simple structure and reliable performance for cooling system and sealing vacuum chamber; the simple structure of electrically conducting parts as circular vacuum copper plate and graphite pressure head, etc. which has the advantages as low energy consumption in conductive chain, better processing rigidity, and high manufacture precision, etc. During the low temperature sintering process, this device may open the door for smoke extraction and reduce the pollution of the vacuum system by the exhaust gas. This utility model is also applicable to take out the processed item and exhaust smoke which could operate conveniently and save times. As upper and lower vacuum cover maintain the meta-locking state all the time during the operation, the sealing ring between the two circular cover can not easily be contaminated and fall off, and the performance is more reliable for dynamic sealing.
Description
Technical field
The utility model relates to a kind of sintering press, especially relates to a kind of vacuum-sintering press vacuum chamber.
Background technology
At present, the vacuum-sintering press vacuum chamber that is used to make sintered metal products such as diamond tool both at home and abroad mainly contains circular vacuum chamber, two kinds of versions of square vacuum chamber.
Circular vacuum chamber structure is made up of the circular enclosure of two band water-cooled interlayers up and down, last cover is fixed and diameter covers greater than following, following cover can move up and down, workpiece is contained between two covers, conductive copper plate is contained in the cover end face respectively and covers the bottom surface down, copper coin and insulation between the cover up and down, the graphite pressure head directly is installed on the copper coin in cover, in last cover, between circle and the following cover cylindrical sealing ring is arranged, the compacting workpiece covers rising at present, be buckled together the formation movable sealing with last cover, can produce mobilely between covering up and down when workpiece is compressed, move up and down by four guide pillars.
Its cooling system structure of circle vacuum chamber is reasonable, succinct, and fax guiding elements such as copper coin and graphite pressure head are simple in structure, the path short, make that the conductive chain energy consumption is little, is equipped with good rigidly when four guide pillars are feasible to be suppressed, and processing and manufacturing is relatively easy, and easily guarantees high accuracy.Vacuum seal leakage link is few, owing to cooling is abundant, makes to seal reliably.Shortcoming one is to pick and place the workpiece inconvenience, vacuum (-tight) housing is broken away from fully and leave certain distance after just can send into or take away workpiece.The 2nd, must two covers fasten in when heating that push-down head could connect on the back, flue gas is bigger during low temperature, and unnecessary vacuum, can only be discharged fume by vacuum system on this equipment, easy contaminated vacuum system.In addition, because two covers need to throw off fully, make that sealing ring between the two is easily contaminated.
Summary of the invention
The purpose of this utility model just is to provide a kind of and picks and places the workpiece inconvenience, is difficult for contaminated vacuum system and the vacuum-sintering press vacuum chamber of sealing ring between two covers up and down.
The purpose of this utility model can realize by following measure:
The utility model comprises the circular enclosure of two band water-cooled interlayers up and down that snaps together, and offers door opening on circular enclosure, and door opening is provided with door.
On the door in the utility model the glass observation window is housed, also adpting flange can be set.Door opening is to be opened on the circular enclosure or down on the circular enclosure.Between door and the door opening flange sealing strip is arranged.At last cover and between covering down sealing ring is housed.Last vacuum (-tight) housing is fixed on the upper beam, and diameter is greater than following cover, and play cover and following copper coin are installed on the sliding beam.Be provided with a neck between door opening on the circular enclosure and the door, certainly, also can not establish a neck.
The utility model promptly offers door opening owing to adopt said structure on circular enclosure, door opening is provided with door.Thereby make it to have following advantage:
1. kept that circular vacuum chamber structure is rationally succinct, cooling system and vacuum seal structure is succinct, the advantage of dependable performance.Kept fax guiding elements such as circular vacuum chamber structure copper coin and graphite pressure head simple in structure, the conductive chain energy consumption is little, compacting good rigidly, accuracy of manufacture advantages of higher.
2. during low-temperature sintering, the smoke evacuation of can opening the door has reduced the pollution of flue gas to vacuum system.
3. can pick and place workpiece and smoke evacuation from door, make easy to operate, save time.
Upper and lower vacuum (-tight) housing remains buckle state during 4. owing to work, makes that the sealing ring between two vacuum (-tight) housings is difficult for polluting, coming off, and movable sealing is more reliable.
