Description
The technical field is as follows:
the utility model relates to a curved field of glass heat, specifically speaking is a curved stove of glass heat.
Background art:
the traditional glass hot bending technology uses a resistance furnace to heat the glass in the furnace integrally, is slow in time and low in heating efficiency, cannot selectively heat a specific area, and may have certain influence on the performance of other areas of the glass. The microwave heating technology has the advantages of high heating rate, low power consumption and selective heating. However, the existing microwave hot bending furnace has the problems of complex structure, inconvenience in use, single process, low hot bending efficiency and the like.
The utility model has the following contents:
the utility model provides a glass hot bending furnace for overcoming the defects in the prior art.
The application provides the following technical scheme:
a glass hot bending furnace comprising; the furnace body, its characterized in that: the glass furnace is characterized in that a material inlet is formed in one end of the furnace body, a material outlet is formed in the other end of the furnace body, a group of microwave generators and thermocouples are arranged in the furnace body, a glass supporting plate is arranged in the furnace body, a female die is arranged in the furnace body on one side of the glass supporting plate, and a forming device correspondingly matched with the female die is arranged in the furnace body.
On the basis of the technical scheme, the following further technical scheme can be provided:
and an infrared thermometer which is correspondingly distributed with the female die is also arranged in the furnace body below the female die.
The glass supporting plate is horizontally distributed and made of stainless steel, and the concave die is made of silicon carbide or graphite.
The forming device comprises a hydraulic pump arranged on the furnace body, one end of an output shaft of the hydraulic pump is inserted into the furnace body, a lower pressing head is arranged at the end part of the output shaft of the hydraulic pump, and a male die which corresponds to the female die and is matched with the lower pressing head is arranged on the lower pressing head.
Utility model advantage:
the utility model discloses simple structure, convenient to use have adopted microwave heating's mode, and rate of heating is high, and the scope is little to improve the curved efficiency of heat, practiced thrift the heating energy consumption. In addition, the arrangement of the heating resistance wires can keep the temperature in the oven cavity at a certain temperature in advance, so that the glass is prevented from being broken due to too fast heating rate under microwave heating or too fast cooling when the microwave is turned off.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in FIG. 1, a glass hot bending furnace includes; the furnace body 1 made of stainless steel is provided with a feed inlet 6 at one end of the furnace body 1 and a discharge outlet 7 at the other end of the furnace body 1.
The furnace body 1 close to one side of the feed inlet 6 is internally provided with horizontally distributed glass supporting plates 5, and the glass supporting plates 5 are made of stainless steel. A group of microwave generators 2 are fixedly connected above the glass supporting plate 5 and on the inner wall of the furnace body 1 which is sent down. The inner wall of the furnace body 1 is also fixedly connected with a thermocouple 10 and an electric heater 9, and the electric heater 9 is a heating resistance wire.
A concave die 4 made of graphite is arranged in the furnace body 1 between the glass supporting plate 5 and the discharge hole 7. A forming device 11 which is correspondingly matched is arranged on the furnace body 1 above the concave die 4. The forming device 11 comprises a hydraulic pump 11a arranged on the outer wall of the furnace body 1, one end of an output shaft of the hydraulic pump 11a is inserted into the furnace body 1, a lower pressing head 11b is fixedly connected to the end part of the hydraulic pump, and a male die 11c made of graphite is fixedly connected to the lower end of the lower pressing head 11b, so that the male die 11c and the female die 4 are correspondingly matched.
An infrared thermometer 8 which is distributed corresponding to the concave die 4 is fixedly connected in the furnace body 1 below the concave die 4. The microwave generator 2, the electric heater 9, the infrared thermometer 8, the thermocouple 10 and the forming device 11 are matched with a control console which is not shown in the figure in an electric signal control mode through leads.
The working process is as follows:
firstly, turning on an electric heater 9, raising the temperature in the furnace body 1 to the annealing temperature suitable for the glass 12 to be processed, preserving the heat, and monitoring the temperature in the furnace body 1 through a thermocouple 10;
secondly, opening a feeding hole 6, putting glass 12 to be processed into the furnace body 1 from the feeding hole 6 by a mechanical arm of an industrial robot not shown in the figure, placing most of the glass on a glass supporting plate 5, calibrating the position until the position where the glass 12 is to be bent is placed on a concave die 4, withdrawing the mechanical arm of the industrial robot from the furnace body 1, and then closing the feeding hole 6;
thirdly, the microwave generator 2 is started through the control console, and the male die 11c and the female die 4 are both made of graphite, so that the male die 11c and the female die 4 are heated by microwaves;
fourthly, monitoring the temperature of the female die 4 through an infrared thermometer 8, and adjusting the microwave power through a control console to keep the temperature stable after the temperature of the female die 4 reaches the softening temperature suitable for the glass to be processed;
starting the hydraulic pump 11a through the console to enable the glass to be tightly formed with the male die 11c and the female die 4, and then closing the microwave generator 2;
sixthly, continuously annealing, finishing the hot bending operation of the glass 12 after the annealing is finished, then controlling the male die 11c to rise through the console, opening the mechanical arm of the industrial robot at the discharge port 7, stretching into the furnace body 1, and taking out the glass 12 from the discharge port 7;
and seventhly, repeating the second step to the sixth step, and continuing the production flow.
