Description

The continuous glass bending furnace of a kind of horizontal cyclic formula

Technical field

The utility model relates to a kind of glass working machine, particularly a kind of circulation continuous glass bending furnace.

Background technology

All to use glasswork in many occasions.Some glasswork has special shape, as arc or angle, to satisfy the needs of different purposes.Because the singularity of glass smelting technology and the diversity of glasswork, above-mentioned difform glasswork can not be with regard to moulding when glass is smelted, but finishes by processing behind glass ware forming again.Bend the used machinery of glass and be called glass bending furnace, it is commonly used is circulating continuous structure up and down, the technology comparative maturity, and the hot bending glass that is used to make even heating bends vehicle glass, building glass etc. as being used to, and efficient and yield rate are higher.But the bending furnace of this structure then is not suitable for when the processing hot bending glasswork of local heating such as tea table, fish jar glass, non-uniform temperature glass often occurs and bursts phenomenon.Therefore, in order to satisfy diversity requirement, be badly in need of existing bending furnace is improved to glasswork.

Summary of the invention

The purpose of this utility model provides the continuous glass bending furnace of a kind of horizontal cyclic formula, is used to bend the hot bending glasswork of local heating, has overcome the defective that glass that existing bending furnace exists easily bursts, and has improved the yield rate of hot bending glasswork.

Realize that the technical scheme that the purpose of this utility model is taked is such.The continuous glass bending furnace of a kind of horizontal cyclic formula, comprise body of heater in the structure, body of heater has thermal insulation layer, in body of heater inner bottom part parallel arranged two row mould vehicle tracks are arranged, in the middle of two row mould vehicle tracks, be arranged at intervals with the insulation column along the track direction, the interval that two-phase is faced between the insulation column is long together with mould vehicle, be positioned at the furnace bottom middle part, be provided with between the two row tracks and track insulated wall in the same way, the body of heater inner bottom part has the nichrome wire of heating usefulness, have vertical respectively and the close vertical reversing track of track at the outside two ends of body of heater with the intravital two row tracks of stove, on two row reversing tracks, the reversing car is arranged, the reversing car is by reversing car traverse rod, perpendicular rail of reversing car and roller are formed, reversing car traverse rod and the intravital mould vehicle parallel track of stove, the reversing car laterally moves on the reversing track by roller, and mould vehicle is led commentaries on classics from two mould vehicle interorbitals.Mould vehicle in the traction apparatus that the traction mould vehicle is arranged at the outside two ends of body of heater respectively and the body of heater on the two mould vehicle tracks links to each other, draws mould vehicle and moves.

Described glass bending furnace is characterized at mould vehicle one end thermal insulation layer being arranged.

Described glass bending furnace, its further characteristics are positions that nichrome wire is arranged on insulated wall.

The principle of work of the continuous glass bending furnace of horizontal cyclic formula of the present utility model is described below:

The mould vehicle that is loaded with glass to be processed enters in the body of heater from the mould vehicle track two ends of fire door respectively under the traction apparatus traction successively relatively, when mould vehicle runs to the nichrome wire position at body of heater middle part, glass to be processed is heated, glass continues to move ahead with mould vehicle after being curved desired shape, meanwhile, mould vehicle on the siding track is entered the body of heater middle part too, the mould vehicle that is loaded with glass to be processed that has just entered body of heater on glass mold car behind the hot bending on such siding track and another track is met and carry out thermal exchange and cooling gradually in operation or stop process, finish heating, glass mold car behind the hot bending has just entered the intravital cold glass mold car of stove with unnecessary heat transferred, owing to be furnished with the insulation column in two row mould vehicle track intermediate section, end in every joint mould vehicle has thermal insulation layer, when every joint mould vehicle enters in the body of heater, in glass mold car when heating at position, mediate, two face mutually the mould vehicle of insulation between the column with to the mould vehicle on the siding track almost in a seal cavity, realize heat exchange, unnecessary heat is fully utilized, thereby has realized energy-conservation purpose.Finish heating, hot bending, the cooled glass mold car of lowering the temperature arrives body of heater one port, unload processed good glasswork, the car that will reverse moves to and the intravital mould vehicle rail end of stove, reversing car traverse rod and mould vehicle track are joined, mould vehicle after the unloading is forwarded on the reversing car, then, parallel mobile reversing car, make it move on to opposite side mould vehicle rail end, again load onto glass to be processed, reversing car traverse rod and this side mold Car Track are joined, mould vehicle is forwarded on this side mold Car Track, continue to enter in the body of heater after articulating with the mould vehicle of front end.Operating process and aforesaid operations to side are identical.Realized that the glass process that bends carries out continuously under the horizontal cyclic condition.

The technique effect that the utility model is obtained is: furnace binding is simple, uniformity of temperature profile in the heating chamber, and the glass cooling behind the hot bending, annealing process are carried out in proper order, the heat gradient exchange, glass is difficult for bursting, and unnecessary Btu utilization is abundant, and energy-conservation order effect is remarkable.
