Compared with prior art, the present invention has the beneficial effects that
1, the open-and-close mechanism of the carrying mechanism of this vacuum brazing stove is able to drive two carrying bar foldings, and elevating mechanism drives
Bar lifting is carried, translation mechanism, which drives, carries bar translation, carries the movement of bar in three-dimensional space to realize, movement spirit
It is living, it is created condition for the multi-faceted support of tablet, resigning mouthful is provided on welding bench, the supporting part carried on bar moves to material
It on the downside of piece, is held up so as to which the tablet on the upside of welding bench will be fully located at, avoiding tablet both ends stretching welding bench causes to become
Shape.
2, it carries bar and welding booth is stretched out by carrying port, and be connected with open-and-close mechanism, not only realize indoor to welding
Tablet is carried, additionally it is possible to tablet is carried in welding booth, and the tablet being welded in welding booth is carried to welding
Outdoor does not need the bell opening being movable into and out for tablet can be realized in the welding process.
3, baffle moves in baffle mounting groove with the movement for carrying bar, so as in time close welding booth, keeps away
Protection gas leakage is exempted from, has reduced the consumption of protection gas, thereby reduce welding cost.
4, open-and-close mechanism is connected with the carrying and installation arm on the downside of welding booth, facilitates the connection for carrying bar.
5, folding power plant module pushes folding guide plate mobile, and the folding guide part for opening and closing guide plate passes through folding directive wheel
Two carrying bar synchronizations are pushed to move in the opposite direction, folding spring can make folding directive wheel compress folding guide plate always
Folding guide part, and then realize the folding of two carrying bars, facilitate the carrying of tablet, additionally it is possible to avoid carrying bar to taking out negative pressure
The work of module counteracts, and the stroke for carrying bar is stablized, and will not damage to end cap.
6, it carries lifting cylinder and pushes lifting guide pad translation, the lifting guide part for going up and down guide pad passes through lifting directive wheel
Translation mechanism lifting is pushed, and then realizes the synchronization lifting of two carrying bars, ensure that carrying bar lifting action stablizes, and rise
The stroke of drop determines, will not damage to welding booth.
7, heating zone can heat tablet, thus make tablet in negative pressure cavity can rapid welding complete, welding
Interior is filled with protection gas, and so as to avoid in heating process tablet from reacting with oxygen, cooling zone can carry out tablet
It is cooling, to keep the tablet temperature for removing welding booth low, that is, avoid tablet and be oxidized, and is convenient in time to the tablet being welded
It is handled, and to being not in since the excessively high mutability of tablet temperature leads to tablet in treatment process in web process
The problem of deforming, disqualification rate is caused to increase, tablet is directly contacted with heating zone or cooling zone, is realized by way of heat transfer
Heating and cooling, compared with using the heating method of radiation, substantially increases heating speed, tablet is enable quickly to heat up
And cooling, reduce the consumption of energy.
8, muti-piece heating plate is spliced into heating zone, and muti-piece coldplate is spliced into cooling zone, same in welding booth so as to make
Shi Rongna muti-piece tablet, heating zone simultaneously heat muti-piece tablet, so that tablet is rapidly achieved welding temperature, improve
Speed of welding.
9, it is equipped with electric heating tube and temperature sensor in every piece of heating plate, every piece of heating plate is made to realize independent temperature
Control, so as to gradually be heated to tablet in material handling process, avoid heating it is too fast cause tablet to deform, also
Avoid heating it is too fast cause tin cream to melt and flow out, lead to rejected product occur.
10, it is provided with intake tunnel and exhalant canal on every piece of coldplate, realizes and gradually cool down to tablet, keeps away
Exempt to cool down it is too fast cause the tin cream after solidification cracked, lead to chip and tablet poor contact, rejected product occur, also can
Tablet is avoided to deform.
11, cooling zone can be condensed the liquid to be formed and is discharged by liquid-collecting cover outlet tube by liquid-collecting cover.
12, each station two sides are provided with resigning mouthful, and supporting part is mounted in flexible module, and flexible module can be adjusted
The position of supporting part avoids the heated softening of tablet, by tablet so as to carry out support to tablet by the two sides of tablet
Tablet deforms and is detached from carrying mechanism when the support tablet of both ends, makes this soldering furnace that can also adapt to the weldering of the soft workpiece of matter
It connects, wide adaptation range, the operation is stable, and the workpiece that can be avoided welding deforms, and improves welding quality, reduces not
The generation of qualified product.
