Embodiment 1

[0026] In this embodiment, the cooling fluid used is low-temperature gas.

[0027] The integrated heating and cooling plate for glass hot bending has two parts: a plate body 1 and a cooling pipe 2, wherein the plate body 1 contains two layers of tube holes 11, and the diameter of the tube holes 11 matches the size of the existing heating tube. One layer of pipe holes 11 is used for placing heating pipes, and the other layer of pipe holes 11 is used for placing the outer pipe 21 of cooling pipeline 2 . Bolt holes for fixing are also provided outside the board body 1 .

[0028] The cooling pipeline 2 part includes a nozzle assembly 25, an inner pipe 22 and an outer pipe 21. The tank mouth assembly is provided with an inner pipe connection 23 and an outer pipe connection 24. There are a plurality of inner pipe connections 23 with The station that the inner pipe 22 is connected, and there are also a plurality of stations connected with the outer pipe 21 in the outer pipe connecti...

Embodiment 2

[0034] In this embodiment, the difference from Embodiment 1 is that the cooling medium used is cooling gas, and the cooling method is input from the inner pipe connecting channel 23 and output from the outer tube connecting channel 24 .

[0035] During the cooling cycle, the cooling gas is injected into each inner tube 22 from the inner tube connecting channel 23, and when the cooling gas reaches the end of the inner tube 22, a part of the gas will flow into the outer tube 21 through the gap between the arc columns, and the other part The air will directly contact the end of the outer tube 21 through the end of the opening. Due to the effect of air pressure, this part of the cooling gas will move to the connecting channel 24 of the outer tube, and take away the heat on the plate body 1 during the moving process. Thus, the cooling efficiency is improved.

Abstract

The invention discloses an integrated heating and cooling plate for glass hot bending. The integrated heating and cooling plate comprises a plate body and a cooling pipe, wherein pipe holes are formedin the plate body, and the cooling pipe is arranged in the pipe holes to be connected with the plate body. An existing simple heating plate is improved, the cooling pipe is added, cooling inside thecooling pipe is optimized through the structure of outer pipes and inner pipes, so that the cooling process is controllable, the problem of energy consumption during proofing in the glass hot bendingprocess is solved, the production efficiency can be improved, and the plate has great significance in the actual production process.

Description

technical field [0001] The invention relates to the field of designing mobile phone glass processing, in particular to a temperature regulating structure in a hot bending process. Background technique [0002] At present, in the production process of 3D curved glass, there are usually two processing methods: high-frequency furnace and precision furnace. The 3D curved glass itself is very thin, and the high-frequency furnace can quickly heat the glass to be bent through electromagnetic heating. Due to the nature of the glass itself, too fast heating can easily cause the thin glass that needs to be bent to break, and this processing method is not accurate. Under the current trend of increasing requirements for curved surface bonding, the scope of application is relatively wide. Small. [0003] As for the precision furnace, the glass is heated and bent by means of heat transfer. The temperature controllable precision is high, and the glass can be heated within the controllable...
