According to the draft tubes and the lifting structure, labor power is saved and labor intensity is relieved, so that quality of processed workpieces improved.
Description
Technical field
The present invention relates to a kind of well formula tempering furnace, be particularly suited for lifting and the structure of body of heater inner draft tube of bell.
Background technology
Existing well formula tempering furnace is made up of body of heater, bell, furnace cover lifting mechanism, body of heater inner draft tube etc., and bell passes through chain sling
Being connected with crane, crane is connected with lifting shaft, and lifting shaft is connected with screw lift.When bell needs to open, start silk
Bar elevator, screw lift drives lifting shaft and crane to hoist, and crane drives bell to hoist by chain sling again, and bell rises
Being raised to specified altitude, then drive bell to open to direction, side by the handle on crane, this manual mode opens bell,
Need at least two people to operate just can complete.Shortcoming: one is waste of manpower, two is that manipulation strength is bigger.
Body of heater is built with guide shell, and blower fan is to be bolted on bell, during blower fan work, and the hot blast in body of heater
It is circulated by guide shell, owing between guide shell and body of heater, air channel is less, affects hot air circulation, cause temperature uniformity to reach
Less than design requirement, thus affect the quality of product.Additionally easily touch guide shell during workpiece turnover burner hearth, cause guide shell to be sent out
Raw displacement, affects the size in surrounding air channel, thus affects hot air circulation.
Summary of the invention
The task of the present invention is to propose a kind of furnace cover lifting to complete with opening a people；It is less that guide shell rocks gap.Improve and produce
Guide shell on the well formula tempering furnace of quality and lift structure.
The task of the present invention is done in such a way that it includes body of heater, burner hearth, it is characterised in that: it is welded with axle in fixed mount
Bearing, is provided with roller bearing in bearing block, be equipped with rotating shaft in described roller bearing, is installed with arm by hanging in described rotating shaft
Arm seat plate is fixed, and the electric pushrod motor on electric pushrod is fixed on support, described arm built with sprocket wheel, each sprocket wheel it
Between connected by chain, be lifted with bell below one end of chain, the other end of chain is connected with electric pushrod, electric pushrod
End is connected with the head end of arm equipped with arm-tie, handle, and the switch that handle is arranged electrically connects with the control line on electric pushrod
Connecing, equipped with guide shell in described burner hearth, described guide shell is suspended on flange, and the inner ring of flange is welded with inner support, inner support
Caving in towards flange inner ring, at the upper end open of described guide shell, companion flange inner ring is provided with boss.Described fixed mount is fixed
In a side of body of heater, described inner support is generally evenly distributed on the inner ring of flange.The boss arranged on guide shell is suspended on
The recess of flange inner ring, the bottom of guide shell is welded with the i-beam frame of ventilation, and shape is M shape.
The present invention has the effect that the bell that the present invention relates to, by bearing manual unlocking, is saved manpower, reduced work
Intensity；The guide shell installed in body of heater is difficult to rock, and body of heater increases with guide shell assemblage gap, increases thermal cycle, thus improves
Process workpiece quality.
