Abstract
The utility model relates to a glass tempering furnace with a temperature control device. The glass tempering furnace comprises a tempering furnace body, heating furnace wires and a porcelain transmission roller, wherein a heat-proof baffle plate is arranged at the edge part of the heating area of the tempering furnace body, and is arranged above the porcelain transmission roller; the distance between the heat-proof baffle plate and heating furnace wires at the upper part of the area is 5 to 10 mm; and the distance between the heat-proof baffle plate and the porcelain transmission roller is 50 to 60 mm. Through the arrangement of the heat-proof baffle plate, part of the heat of the heating furnace wires at the upper part of an area is separated, and the heat convection between the area and the whole heating area is reduced, so that the furnace temperature of the area at the edge part can be reduced stably, the process requirements of lower temperature of narrow edges of tempered glass can be met, the problem in adjusting partial furnace temperature in a heating chamber can be solved, and the temperature of the area can be adjusted stably. The glass tempering furnace can be used in various horizontal tempering furnaces, has the advantages of simple structure, economical and practical use, and convenient popularization, and facilitates product quality improvement.
Description
Technical field
The utility model relates to a kind of glass tempering furnace, particularly a kind of glass tempering furnace that has temperature control unit.
Background technology
Toughened glass is building materials, furniture, the indispensable material of vehicle glass, in recent years, China's toughened glass output ranks first in the world always, along with the continuous progress of production technology, the Application Areas of toughened glass is increasingly extensive, and the kind of toughened glass, specification get more and more.The production of annealing furnace unit is the important component part of China's conventional equipment production, electronic product, and present state of the art, output all occupy first place in the world.
Hole according to the design needs dig out different shape on toughened glass become sophisticated processing technology, and its narrow limit in the tempering process of the glass after digging a hole often is difficult to satisfy technical requirements, and subject matter is to produce defectives such as wavy edge, flounce.Trace it to its cause, produce the toughened glass temperature low 20-50 degree of narrower its temperature of toughened glass of width than stock size, and conventional annealing furnace temperature control unit adopts computer control, the mode of taking to increase or reduce process furnace silk power is come controlled temperature, this method particularly obviously exists not enough in application process in the toughened glass process that processing is dug a hole, can not well solve the temperature isolation in the heating region, cause temperature control to lose efficacy, and then cause the defective of product.Improve front glass annealing furnace such as Fig. 1, shown in Figure 3.
Summary of the invention
The technical problems to be solved in the utility model: overcome defective of the prior art, a kind of simple in structure, glass tempering furnace of having temperature control unit is provided.
The technical solution of the utility model:
A kind of glass tempering furnace that has temperature control unit comprises annealing furnace body, process furnace silk, transmission porcelain roller, and portion is provided with thermal baffle on the heating region limit of annealing furnace body, and thermal baffle is positioned at the top of transmission porcelain roller.
Described thermal baffle is the 5-10 millimeter apart from the distance of top process furnace silk, apart from transmission porcelain roller 50-60 millimeter.
Described thermal baffle is placed on the support, and is fixed on the annealing furnace body by support.
The preferred insulating cotton plate of described thermal baffle, preferred thick 15 millimeters of the specification of insulating cotton plate, long 800 millimeters of wide 200 millimeters, every joint.
The beneficial effects of the utility model:
1. the utility model is by being provided with thermal baffle in the heating region limit of glass tempering furnace portion, the part heat that cuts off this top, zone process furnace silk, reduce the convection current of this zone heat and whole heating region heat simultaneously, reach the purpose of this limit portion zone furnace temperature of steady decrease, satisfied the lower processing requirement of narrow limit temperature of toughened glass, solve the partly-adjusting difficult problem of furnace temperature in the heating chamber well, guaranteed the regulation domain temperature-stable.
2. the utility model can be used for the various horizontal annealing furnaces in home and abroad, the toughened glass of digging a hole especially for annealing furnace unit production abnormal shape, toughened glass as occasions such as public transit vehicle lathe, furniture, household electrical appliances, laboratories, the narrow limit of the toughened glass outward appearance of producing is good, has avoided narrow limit to produce defectives such as wavy edge, flounce.
3. the utility model is simple in structure, and cost is low, and is economical and practical, helps improving the quality of products, and is convenient to promote.

Fig. 3: the side schematic view that improves the front glass annealing furnace;
Fig. 4: the side schematic view that improves the back glass tempering furnace.
Among the figure, 1 is top process furnace silk, and 2 are the transmission porcelain roller, and 3 is top process furnace silk, and 4 is thermal baffle, and 5 is support, and 6 is the preheating zone, and 7 is the heating zone, and 8 is shaping area, and 9 are the cold blowing district.
Embodiment
Embodiment one: referring to Fig. 2, Fig. 4, a kind of glass tempering furnace that has temperature control unit, comprise annealing furnace body, top process furnace silk, lower heating stove silk, transmission porcelain roller, portion is provided with thermal baffle on the heating region limit of annealing furnace body, and thermal baffle is positioned at the top of transmission porcelain roller.Divide preheating zone, heating zone, shaping area and cold blowing district in the annealing furnace body.
Described thermal baffle can adopt the insulating cotton plate, preferred thick 15 millimeters, wide 200 millimeters of the specification of insulating cotton plate, 800 millimeters of the every joint length of insulating cotton plate.Thermal baffle is the 5-10 millimeter apart from the distance of top process furnace silk, apart from 50 millimeters of transmission porcelain rollers.The insulating cotton plate is placed on the support, and is fixed on the annealing furnace body by support.
The principle of work of temperature control unit: utilize the physical constraints mechanism of heat insulation to cut off heating source, the local heat convection current that cuts off room temps makes the temperature-stable of control area in lower level.Treat that the narrow limit of toughened glass back and forth runs on the overlay area of thermal baffle in the heating zone, satisfied the lower processing requirement of narrow limit temperature of toughened glass.Other production processes are consistent with common toughened glass.
Use this glass tempering furnace can make the power of top process furnace silk reduce 10%-15%, the glass temperature temperature reduces the 20-30 degree.
Embodiment two: and embodiment one is basic identical, and difference is:
The thermal baffle of glass tempering furnace is 8 millimeters apart from the distance of top process furnace silk, apart from 55 millimeters of transmission porcelain rollers.
